Drawing of clamps for guitar. Do-it-yourself quick-release clamp. DIY corner clamps

Anyone who has had to do something with their own hands in the direction of improving their own home does not need to talk about the importance various kinds clamps and clamps. Without their presence, it is impossible to imagine both carpentry and plumbing. To properly process any part, you need a clamp. You can easily make it yourself at home using the most basic tools.

Types and types of clamps

Mechanical clamping devices differ both in purpose and in the material from which they are made. Main starting materials are and wooden beam.

Sometimes clamps are assembled in a rather complex spatial configuration: they provide both horizontal and vertical compression of the workpiece being processed. For assembly when constant supervision is required right angle, the corner clamp is very convenient. It’s quite possible to do it yourself, but it’s better to practice on less complex structures.

Clamps also differ in the type of elements that create mechanical compression. The most common are clamps based on a screw mechanism. But anything that can provide the necessary compression force can be suitable for the design. Even those cut from old car cameras.

Why not just buy them?

In any tool store, clamps are presented in a more or less wide range. And any master has a sufficient number of them in his arsenal. What usually stops a craftsman from buying another one? Firstly, the price - quality tool cannot be cheap by definition. Secondly, it is not always possible to find what you need. A self-made clamp to perform a specific task ensures the process of assembling the product on an individual basis. This is not always possible to achieve using a universal clamp from a tool store.

Disadvantages of the standard tool

On construction market You can find a lot of clamps that look like real ones and are expensive, but they only work for a very short time. They are usually made in China. They will have to be thrown away along with the money that was paid for them. Most often it fails; it is made from a cheap, low-quality alloy. If you don’t want to throw money away, then you should think about how to make a clamp with your own hands. This will not only result in another useful thing in the master’s instrumental arsenal, but also an increased level of skill and self-esteem.

DIY clamp: what is needed to make it

First of all, you need to acquire a high-quality timber made of hardwood or a piece of rolled metal profile (preferably a channel section) - this is the basis on which the stop and screw mechanism should be mounted. The most important element clamps is exactly it. A bolt with a large thread profile nut is best suited. To assemble the structure into a single whole, you will need a drill with attachments and standard bolt fasteners. Making clamps with your own hands does not require outstanding qualifications, but you should still have basic carpentry and plumbing skills.

Making a clamp

The most important advantage of a homemade clamp is its narrow focus on providing a specific technological operation. That is why it is necessary to carefully measure everything and sketch out a schematic drawing of the future product. A self-made clamp can and should last a very long time, but this will only happen if it is competently designed and assembled correctly.

A stop and a screw mechanism must be mounted on the supporting frame beam. The free movement of the screw provides sufficient force for compression. The fastening of the stop and the screw with the nut must prevent them from being pulled out of their fixed position when technological force is applied. An important point is the presence of a flywheel mounted on the head of the process screw. If it is not provided for and not carried out, then the compression of the clamp will have to be done with the help of which is neither productive nor functional.

For the purpose of possible use of the clamp as much as possible more operations, the emphasis on it is usually performed in the form of a removable block, which can be placed in several fixed positions. For assembling large wooden planes, it makes sense to construct a more complex clamp in the form of a system of two or more screws mounted on the same frame base. The efforts invested in the manufacture of a technological tool always give the proper return when using it.

Repair and manufacture of furniture, various wooden or metal products not possible without the use of clamps. Modern tool stores offer large selection these products. Conventionally, they can be divided into two large groups. The first combines clamps using threaded parts. Clamps of this group are called screw clamps. They can have a stationary bracket of one size or another or a sliding one.

The second group includes clamps that are based on wire or flat springs and are called spring clamps, respectively.

Any craftsman may need up to several dozen different clamps for his work. Purchasing such a number of tools will require a sufficient amount cash. It is much more economical to make the clamps yourself. About how to make various types DIY clamps will be discussed later.

Making a screw clamp

A simple screw clamp can be made by having a steel sheet 8-10 millimeters thick, a ready-made M8 or M10 threaded rod and several nuts of the same size.

First, using a template or other ready-made clamp, mark the bracket on the selected workpiece. In this case, it is possible to take into account the requirements of the specific operating conditions of the clamp and produce a bracket of the required size.

The next stage is cutting out the workpiece. Thickness and geometric shape blanks for the future clamp makes it problematic to use an angle grinder for this type of work. In this case, it is better to use an acetylene torch or gas cutter.

At the stage of grinding the edges of the resulting bracket, an angle grinder can also be used. Align the edges according to the marking line and remove the corner burrs.

For a screw clamp, weld several M8 or M10 nuts on the short side of the bracket. Instead, you can use a piece of hexagonal rod 40-50 millimeters long with an internal thread of the appropriate diameter.

To operate the clamp, select a round rod with the appropriate thread of the required length. Weld a transverse handle to it at one of the ends.

To protect the finished clamp from corrosion, coat the surface of the product with any oil or nitro paint.

Manufacturing a screw clamp with a sliding frame

If necessary, it is not difficult to make a clamp with a sliding frame.

For work you will need the following materials:

steel strip with a cross section of 40x (8-10) mm;
threaded rod 10-150 mm long;
several nuts and round washers.

The tools you should prepare are a grinder, a drill and welding machine, gas or electric.

The first stage is cutting the strip into pieces of the required length. We will need a stand 500 - 800 mm long, a support bar 200 mm long and a movable bar of the same length.

Using welding, attach a stationary stop to one of the ends of the long part. To ensure maximum structural strength, try to obtain a high-quality seam and select the correct welding modes.

The next stage is processing the sliding bar. It is necessary to mark and make two holes in it, one of which is round, and the second rectangular shape.

Making cylindrical holes using an electric drill or drilling machine will not be a problem. You just need to select a drill of the appropriate diameter, securely clamp it in the tool chuck and drill. The diameter of the round hole must be larger than the diameter of the threaded rod.

Making a rectangular hole will require a lot of time and energy. Stepping back from the edge of the bar 25 millimeters, along center line mark a rectangle 11x41 mm. A small gap will be needed for the plate to move freely along the rack. Next, mark the centers of the holes, retreating 5 millimeters from the edge of the groove and 10 millimeters from each other. To prevent the drill from slipping, the centers of the holes must be pre-punched. Drill four holes with a diameter of 10 millimeters. Give the final shape of the groove by hand using a square or rectangular file.

Over round hole sliding bar, weld a nut with a thread corresponding to the rod. Weld a cross handle to one end of the screw, and a round washer of sufficient thickness to the other. Clean the edges of all parts from metal burrs sandpaper and assemble the clamping fixture.

Making a corner clamp with your own hands

The manufacturing process of a number of products, such as door frames, requires joining parts at right angles. For reliable fixation constituent elements of wood or metal structures corner clamps are used.

A similar clamp can also be made from scrap materials yourself. You will need two pieces of steel angle 40x40, 50x50 or 30x50, 200 millimeters each, a piece of 10x50 strip 250 millimeters long, and two ready-made screw clamps.

Using a bench square without a block to control squareness, install all structural parts in accordance with the photo.

Using a welding machine, attach the corners to the strip with reverse side.

Also welding seam Attach clamps to bases for secure fastening.

Thus, you will get a convenient and reliable device that will repeatedly help you out when performing a number of jobs.

Dear readers, if you have any questions, please ask them using the form below. We will be glad to communicate with you;)

Every craftsman who makes products and parts made of metal or wood cannot do without homemade clamps. Previously, such a tool was produced in various modifications, from specialized to universal. The main task is to fix the workpiece for processing and joining operations. Let's look at how to make a quick-release clamp with your own hands in various variations.

Angle clamp

This type of do-it-yourself metal clamp is designed to fix two objects at right angles and connect them to each other using any methods, however, the main purpose is as a jig for welding metal parts at the angle required for work. To make it properly , you will need the following components:

Corners should be welded at 90 degrees to metal or steel plates. We fasten the worm-type structure by welding, and screw a pin-collar into the working nut in order to assemble a stop at the end. The stop must turn freely. Then we need to drill a hole on the back side where we insert a metal rod as a lever. Incredible simple design and practicality of use have become the key to the popularity of such a clamp among everyone who works with metal and products made from it.

Carpenter's clamp

Such designs, used in carpentry, there are the following types:

Standard clamp, which is the most popular or simple;
In the form of a caliper for small parts and quick fixation;
Self-clamping clamp for milling processes and working with workpieces of various heights.

The first type is made from two pine blocks, a locking nut, rods, threaded wing nuts and thrust washers. The manufacturing process is very simple:

We cut out the working pliers from the bars, drill holes for the studs, taking into account a small amount of play;
We screw in the studs and lock them using appropriate methods;
We ensure alignment with nuts, made either in the form of wings or standard nuts for improved tension.

The second option is used when prompt fixation of small parts is necessary. Production is carried out from small bars and thin-sheet plywood. Furniture nuts and collar pins act as a worm system. One stop is stationary; we attach it to the end of the guide rail, in which we cut out recesses to fix the moving mechanism.

There are both portable and stationary versions of this design, where grooves are cut for movement with the fastening of fixed stops. The clamp is a furniture nut, a hairpin and a knob. Due to this, you can work with workpieces of any size.

The self-clamping design has a lever with an eccentric at the rotating end. We turn it at a certain angle, a quick clamp is automatically obtained. The height is adjusted with a pin on the workbench. It is made individually for each matrix, depending on its purpose and the purpose of the work being carried out.

Pipe clamp

Welding metal pipes end to end is a complex operation. It is considered simpler to weld the pipe to ready-made system. The design for such cases is made of metal corner and steel plates. The halves of such a device should be fixed traditional method, namely threaded studs. As a result, you can get a fairly simple and effective design, which will greatly facilitate the work when welding pipes with various designs.

There are other types of designs, including cam mechanisms, tape and wire clamps, which can be useful for working with specific structures, including particularly fragile and thin ones. However, their production is the subject of separate master classes and articles on specialized resources.

Homemade clamps are indispensable assistants for any craftsman working with metal and wooden parts and products. Making them is quite simple and very exciting. Here it is important to follow the manufacturing technology, find optimal instructions and videos. You can buy clamps, but they may ultimately not be suitable due to the specificity of the workpiece or work. This is why you should make your own clamps. Good luck working with various workpieces and making homemade quick-release clamps!

The clamp is an auxiliary tool , which is used to fix the boards when they are connected in a given position. The clamp is also suitable for holding boards while sawing them, for routing hacksaw blade, connections of various elements. Parts that require machining can be inserted into the tool. Then, using a movable element, they are clamped with jaws and begin to work. To securely hold parts in in the right position It is recommended to use two or more clamps.

Homemade clamps are often made of metal or wood, and in terms of their characteristics they are not much inferior to purchased, factory-assembled ones. Since the design of the clamping device is simple, it will not be difficult to understand the principle of its operation in order to make it yourself.

Making a metal screw clamp

Before starting work you will need to prepare necessary materials. For the base of the structure, a steel sheet one centimeter thick, or any even trim of the same thickness, is suitable. The length of the workpiece is arbitrary, but they try to choose it taking into account the working distance of the clamp.

Main materials of manufacture:

steel sheet;
long bolts;
nuts

A drawing is being drawn up. The future body of the tool is marked on the workpiece material, which in appearance resembles the letter “C”. Instead of steel sheet you can use a section of profiled pipe, bent in the shape of the letter “C”. Special requirements no to the thickness of the workpiece, but the design must be reliable. The choice of length is made taking into account the dimensions working area, processed parts.

After marking is applied, the part is cut out of metal. At home preparations small sizes can be cut using a grinder. But when making clamps of large dimensions, it is recommended to use a gas cutter or an acetylene torch. The next stage is processing and polishing the workpiece. All sharp edges and sagging formed when working with gas welding equipment are knocked off with a file, and the surface is sanded with sandpaper. This must be done so that when clamping the workpieces, you do not cut yourself on sharp edges.

Having prepared long bolts M 8, M 10, proceed to fastening the moving element. Why are nuts welded on one side of the workpiece under the selected bolts? If there are no bolts, you can select hexagons or steel rods of the required length with pre-cut threads.

At the inner working end of the screw, a flat, even part is welded, on which the function of the jaws is assigned. On the back side of the screw, a lever is attached by welding from scraps of a stud. Its presence will speed up the process of clamping workpieces , further reducing the amount of effort applied. This completes the assembly of the clamp with your own hands.

Corner clamp device

When making corner tools for furniture assembly, it is important to accurately maintain a right angle of 90°. Main available materials are corners with steel strips. To work you will need:

40 mm steel angle 3-4 mm thick;
steel plates 40-50 mm;
threaded studs;
rods for gates;
nuts;
welding machine;
electric drill, taps.

The corner clamp is the most difficult to manufacture, but when carrying out some types of work you cannot do without it. At the initial stage, corners are welded to the steel plates at right angles, and nuts are welded to each corner, which will serve to create a worm-type structure. Another option is to drill a hole in the corner and cut it using a tap. internal thread. The width of the working gap is selected taking into account the size of potential workpieces, but too large a stroke of the clamping wheel reduces the strength of their fixation.

For processing parts various sizes It is recommended to prepare several clamps!

The stud is screwed into the welded nut. At its end there is a stop made of metal washers various diameters, which should scroll freely when the pin rotates. On the back side of the knob, a hole is drilled for a metal rod. Used as a lever, it will transmit more force, so it will hold workpieces more reliably.

Wooden clamp - made from leftover boards

The most popular is a wooden quick-release clamp, but a tool of a similar design can also be made of metal. Despite the simplicity of the design, it is very convenient when performing various tasks.

The presence of two identical clamps expands the scope of their application!

For assembly you will need to prepare the following materials:

pieces of boards;
studs with pre-cut threads;
nuts and wings corresponding to the threads of the studs;
slats.

First, two studs of the same diameter with threaded threads are prepared. They must be 200 mm long. The nuts are matched to the threads of the studs. Two slats are prepared, preferably made of wood hard rocks. Best choice there will be oak, beech, birch, ash. The slats are adjusted to the same size. To do this, the excess length is sawed off and the cut is sanded. After this, two holes are drilled in each of the slats with a small tolerance. Moreover, the locations of the holes on each of the workpieces must match perfectly, and their diameter must correspond to the diameter of the studs.

Strips of plywood can be glued to the surface of the slats. They are customized to size wooden blanks, drill holes. The studs are inserted into the holes obtained and securely fixed with nuts on one of the rails on both sides. To prevent material from pushing through, washers are placed under the nuts. This bar will always be stationary, but the other one will be able to move freely along the guides in the form of pins.

Another bar is installed. To do this, thread it through the studs and push it into place. The clamping is carried out using ordinary nuts and an open-end wrench, but for convenience and increased performance it is necessary to install wing nuts. Check the movement of the fastener; if it is difficult or additional adjustment of parts is required, or other defects are found, then they are eliminated. The work on assembling the clamping device from wood can be considered completed; all that remains is to test it in action.

Properly assembled clamping devices allow you to securely fasten wooden parts during carpentry work. The designs of the listed types of fasteners are popular and are so simple that they can be made independently from scrap materials using minimum quantity tools.

A clamp is a tightening clamping device that is used in working with wood and metal, paper and leather. In carpentry workshops, using clamps, parts, boards and panels are glued together, when welding work ah clamp tightly parts of metal products. In office work they are used when filing documents for archiving, and in auto repair shops they clamp parts of the mechanism when repair work. The shoemaker uses it to glue the soles together better.

A clamp is also a necessary part for household use. They can be used to attach a pencil sharpener to your desk or table lamp to the bedside table. Even when replacing the battery in a good expensive watch, you will need the help of a clamp to tightly close the back cover. After all, with high-quality tightness, it closes very tightly.

You can buy a ready-made clamp in a store, but usually production requires several different products at once, and they are quite expensive, so most craftsmen are starting to think about making a clamp with their own hands.

Types of clamps

Required for work different types such clamping devices. They are made of metal or durable wood. They happen different shapes: F and G-shaped, tape, edge, pipe, quick-clamp, screw, corner or mounting. But no matter how the clamps differ in their design and appearance, the purpose of all devices is the same: to firmly fix the products for further processing or connecting parts together.

Metal corner clamp

By making such a structure yourself, you can firmly connect not only wooden but also metal parts together. These clamps are used for welding.

To work, you need a steel corner with a thickness of 4 mm and a size of 40 mm, 50 mm plates, threaded rods, nuts, washers and rods, a welding machine, and a drill.

At an angle of 90 degrees you need to weld the plates to the corners. On each side, also attach a worm-type structure by welding, which is a small piece of an angle with a welded thrust nut, into which a crank with a hole for a metal lever is screwed on top. On the opposite side, a thrust mechanism consisting of two washers is assembled. The stop rotates freely on the pin.

This corner clamp is reliable fastening parts at right angles, which can be used not only for welding, but also in a carpentry workshop when working with wood or plywood.

A simple model for gluing corners

To make such a clamp with your own hands, you will need four steel corners of the same size, a threaded rod, two wing nuts, a drill, and a welding machine.

Two corners are welded together at right angles, obtaining an even square in cross-section. The next step will be welding threaded studs inserted into the drilled hole along the same diameter. It is also necessary to drill holes in the remaining corners. The finished clamp is easy to assemble. To do this, you just need to clamp the glued wooden parts using wing nuts.

If it is necessary to glue large planes, you can take steel corners longer length and install additional studs at the bottom of the clamp.

Homemade band clamp

This type of clamp is often used to make picture or photo frames. This clamp is a universal mobile mechanism that can be used to glue the corners of frames of various sizes.

To make such convenient device You will need 6 mm plywood, a wooden block, thick plywood 10-15 mm, a jigsaw, a screwdriver, a metal square, a simple pencil, thick tape with a clamp, bolts, washers, wing nuts.

The first step is to make a “table”. To do this, take a rectangular sheet of plywood and screw two wooden blocks from the bottom on two opposite sides. Next, you need to clearly measure and draw the diagonals along which the slots for the structure will be cut with a jigsaw.

The next step is to make four frame holders from thick plywood. First you need to cut out 4 identical pieces of rectangular plywood, then use a metal triangle to outline identical right angles on one side and cut them out. You also need to make a slot for the bolt so that the clamp has mobility and can move left and right. To prevent the tensioned tape from slipping off, you can cut a recess on the opposite side of the corner.

Quick clamp

This type of clamping mechanism is designed for work that does not require particularly strong and tight compression of parts, since it does not have a strong connecting effect. With such a clamp you can temporarily and quickly fix a part, for example, when cutting. It works due to an eccentric located in the middle of one of the parts of the clamping device.

For production you will need wooden blocks or thick plywood, metal plate, self-tapping screws, screws, bolts, drill, circular saw, sandpaper.

The first step is to prepare the wooden blocks. Their shape can be different, at the request of the master. It doesn't matter much. A cut is made in the rear part, approximately 6-7 cm. A metal plate with pre-preliminary drilled holes and bolted securely. On the moving part, the fasteners do not pass through the plate, but are located along the edges. The bar should move up and down.

Then work continues on the moving part. A longitudinal cut is made on the saw, leaving a thin strip at the bottom. It will act as a clamp and should move. The cut is also made for the eccentric, which is screwed into the upper part of the part.

The eccentric is easy to perform. Using a compass, draw a semicircle on paper, the ends of which are connected by an angle. The result is a drop shape. Transfer the dimensions onto thin plywood and cut with a saw. In order for this part to fulfill its role and exert pressure on the moving part of the bar, we shift the center of the semicircle by 1 cm and drill a hole, attaching it to top bar with a screw. When the eccentric is turned, the part is tightly fixed and quickly clamped.

Table Clamp

The table clamp is very convenient to use and easy to implement. Take a wooden beam, a piece of plywood, bolts, a drill, a threaded rod and a metal stick for leverage. Two bars are bolted onto a sheet of plywood and placed motionless on the table. Then the clamping device itself is installed.

A hole is drilled in one of the bars, into which a threaded pin is inserted, securely screwed into the smaller bar at a right angle. A lever is inserted onto the free end for convenience. Very quick and easy, even a beginner can do it.

Simple wooden clamp

This G-shaped structure is designed to hold two planes when gluing. Having made several copies, you can fix all the corners. To work you will need a wooden beam, plywood, a threaded rod, a nut, and screws.

Having twisted three identical pieces of wooden beams, we firmly fix them with two rectangular pieces of plywood. Next we drill a hole for the stud. To make it move well, you can tightly drive a nut into a wooden beam, on which the pin will rotate freely. The handle can be made at your discretion either wooden, or by inserting a simple lever from a metal stick.

Installation of the lamp

Using the clips, you can move the table lamp to a place convenient for reading: on desk, bed, nightstand or hanging shelf. The lamp on a clamp is easy to use, which is why it is popular.

Quick-release devices such as clamps can be used in all areas of life and production. Making them with your own hands is not difficult, you just need to allocate a little time and have the desire. Good luck!
