A DIY clamp makes the craftsman’s work easier and saves him money. A clamp is a clamping device for fastening parts

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 figure out how it's made quick clamp with your own hands in various variations.

Angle clamp

This type of do-it-yourself metal clamp is designed for fixing two objects at right angles and connecting each other using any methods, however, the main purpose is as a welding jig 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 with reverse side it is necessary to drill a hole 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 parts small size and operational 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:

1. We cut out the working pliers from the bars, drill holes for the studs, taking into account a small amount of play;
2. We screw in the studs and lock them using appropriate methods;
3. 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 the finished system. The design for such cases is made of a metal angle and steel plates. The halves of such a device should be fixed using the traditional method, namely with threaded rods. 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 irreplaceable 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 the best 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!

Reading time ≈ 5 minutes

A clamp is a tool that resembles hand vice, which is used for securely fixing or gluing two elements. For example, in carpentry it is used to connect two planes while drying. adhesive solution. However, this tool is not always at hand, so you can resort to making a quick-release design yourself. To properly make a metal clamp with your own hands, you need to follow step-by-step instructions with photos and video master classes.

Design Features

A clamp can quickly fail, which is why it is so important to know how to make homemade instrument. Components This metal structure consists of a lever part, a frame, clamp lips and a moving part.

What are the advantages of clamping tools:

The clamp can also be made from wood, however metal structure more practical and reliable. Its production does not require special knowledge and skills; you only need the use of welding equipment, a hacksaw and a torch. The whole process with step by step instructions shown in the video.

Models of clamping tools are divided into the following classes based on the operation of mechanisms and structural features:

Manufacturing technology

A do-it-yourself metal clamp is much more reliable and practical. wooden structure. For the manufacture of homemade units required welding equipment and locksmith units.

Tools for making any type of clamp

1 option

Following the instructions, you can make a homemade clamp from metal reinforcement.

Option 2

To make an angle clamp tool with your own hands, we will need following materials: steel trim from corner 40*40, 50*50 and 30*50 200 mm each, 2 F-shaped clamps and a strip 10*50 up to 250 mm long.

Let's get started:

Purchasing clamps in hardware stores is quite expensive. Everyone wants to rid themselves of extra costs, if there alternative options. You may need several such tools at once, this is especially true when assembling, manufacturing or repairing furniture. Homemade clamps will replace your hand vice, as you can choose the model, type and size of the tool. By following the instructions in the photo and video, you can quickly understand the manufacturing mechanism and quickly make a manual clamp from scrap materials.

A clamp is a tool that allows you to fix a part during processing. Masters often use different kinds clamps in their work. Whether you are a carpenter or a mechanic who processes metal, there is always a need to use it.

This device is available in different options, from universal to specialized. Relatively recently, a new modification has appeared: a quick-release clamp. Develops compression force up to 450 kg.

The task for all types is common - to fix the workpieces for processing or connecting to each other.

Like any other tool, clamps can be purchased at the store or made yourself. The second option is often chosen by professionals. It’s easier to come up with your own design than to look for an option for individual tasks.

Homemade clamps - varieties and manufacturing technologies

Angle clamp

Such devices are used to fix two objects (not necessarily the same size) at right angles, to connect them together in any way. It can be wooden blanks when gluing or assembling using corners and confirmat.

However, most often, an angle clamp is used as a jig for welding metal parts at right angles.

For production you will need:

• steel corner 40 mm, thickness 3-4 mm;
• steel plates 40-50 mm wide;
• threaded studs, preferably hardened;
• rods for gates;
• nuts for the worm gear;
• welding machine;
• drill, taps.

We weld the corners to the steel plates at a strictly 90° angle.

We attach a worm structure to each side by welding. This is the same corner with a welded-on thrust nut or thickening, in which a thread is cut in accordance with the collar pin. The width of the working gap is selected according to the potential workpiece.

IMPORTANT! If the range of sizes of the parts being processed is too wide, it is better to make several clamps. Too much movement of the knob does not contribute to a strong fixation.

A collar pin is screwed into the working nut, after which a stop is assembled at its end. As a rule, this is a design of two metal washers different sizes. The stop should rotate freely on the pin.

Anyone who has had to do something with their own hands in the direction of improving their own home, there is no need to talk about the importance of various types of 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 They differ both in purpose and in the material from which they are made. The main starting materials are wooden beams.

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 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. Do-it-yourself clamp made for execution specific task, provides 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 the 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 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 the 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.

In order to possible application Clamps in as many operations as possible, the emphasis on it is usually made 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.

In order to speed up and simplify the work process, for example when working with metal products, you will need a couple of corner clamps! In addition, after welding, the metal clamped into the clamp does not move as it would without it, and the angle remains 90 degrees.
It’s not difficult to make a corner clamp with your own hands; it’s enough to have small leftovers on hand profile pipe, a stud, and, of course, bolts and nuts, which I think everyone has.

Visually, the clamp can be divided into two parts: the base and the clamping part.

First of all, we make a base from a 25*60 corrugated pipe as shown in the photo.

Base made of profile pipe 25*60

First, you can assemble it using tacks, then completely weld the seams and clean them well with a grinder.

Then, from the same 25*60 pipe, we cut two 160 mm sections and weld them along the edges. You only need to cook from the outside and the ends, because... With inside the workpiece will be pressed and the seam may interfere.

We weld the outer jaws 90 degrees to each other.

The outer and inner clamps must be exactly 90 degrees relative to each other; after welding, make sure that they do not move or move away.

The next step is to make a mount for the clamping part.

We cut a piece from a 40*40 pipe 30 mm long and cut off one of the sides, making it the letter “P”, then weld it to the base. To attach the screw, we need to drill two holes at 8 and the third (lower) hole at 10 so that the socket wrench would fit into it (you will understand why later).

We make a fastening for the screw.

We're done with the first part, now let's move on to the second.

From the same 25*60 pipe we make internal clamps (jaws), according to external parties I got 105 mm.

We press them with clamps to the external clamps and weld them together.

We make internal clamps.

We cut out two triangles 2 mm thick and weld them to the internal clamps at the top and bottom. We drill a through hole (in two triangles) for 8.

We weld two triangles and drill a hole.

To fasten the screw in one and the other part, we weld nuts 8 and 14 together (as shown in the photo). We make two pairs.

We make a fastening for the screw.

We screw one nut onto the screw, and for the second you need to prepare it.

We grind the screw in a circle slightly larger than the width of the nut and cut the thread at the end to 8. We put a washer on it, the main thing is that it is smaller diameter than the screw thread, put on a fastener welded from three nuts and tighten the bolt. The fastening should rotate freely, and the groove was made so that when the screw rotates, the nut does not screw onto it, but rotates freely.
