What Is a Bench Clamp?

Vices, also known as vices and vices, are a tool that holds and fixes workpieces for processing, and is widely used. It also has more varieties. The vice is a necessary tool for the fitter, and also the reason for the name of the fitter, because most of the work of the fitter is done on the vise, such as sawing, filing, hoeing, and assembling and disassembling of parts. The vise is installed on the bench, and the width of the jaw is used as the standard specification. The common specifications are from 75mm to 300mm. ^[1]

Vice, also known as vice, is commonly known as vice. The vice is an essential tool for electricians. The appearance of the vice is shown in Figure 1.

The structure is mainly a movable clamp body, a fixed clamp body, and a base. Screws and other parts. The movable clamp body is installed on the fixed clamp body, and the movable clamp body is driven to move in the groove of the fixed clamp body through a lead screw with a trapezoidal thread, so that the jaw can be opened and closed. The fixed clamp body is connected to the base, and the base is fixed on the bench by bolts. There are two types of vise, which are fixed on the bench and can not rotate freely and can rotate freely. The general picture shows the types that can rotate freely. Rotate the jaws to the proper position to lock the vise position by the locking handle.

The handle drives the movement of the tong body by driving the screw rod. It has two force-increasing mechanisms. One is the force-enhancing force of the handle and the force-enlarging force of the trapezoidal thread drive. , Can reliably fix the workpiece, thereby ensuring that the workpiece will not move in any way when a large force is exerted on the workpiece when the fitter works. But it is also because the clamping force is too large, which may damage the workpiece surface. When clamping the workpiece surface to protect it from damage, you need to pad something softer than the workpiece between the workpiece and the vise jaw to protect the workpiece. Such as paper or soft metal.

Vice vise

Bench vices are also known as vices and vices. It is installed on the workbench, used to clamp the workpiece, and used for assembly, repair and processing by the fitter. It is a commonly used clamping tool.

Bench vise can be divided into three types: fixed type, turntable type and table rolling type.

1. Fixed bench vise: This bench vise consists of a movable vise body, a fixed vise body, a jaw iron, a screw rod, a guide nut, a compression ring, a base and a rocker handle. The lower part of the movable vise body of the bench vise is square, which is installed in the square hole of the fixed vise body and can be moved. The jaw iron (also known as the clamping surface) is made of prismatic teeth, and is fixed on the movable jaw and the fixed jaw with the hexagonal screws. The jaw iron can be replaced after it is damaged or worn. The screw rod is made of trapezoidal thread. It passes through the eyelet of the movable pliers body. One end is restrained by the washer on the movable pliers body. The other end is screwed into the guide nut. The screw rod is shifted back and forth in the guide nut, and the movable tong body is caused to move correspondingly in the fixed tong body, so that the two jaws are closed or opened. When the movable jaw is closed to the fixed jaw, the workpiece is clamped, and the workpiece can be taken out when opened. An eyelet is made on each side of the base of the fixed vise body so that the device can be fixed with bolts to fix the entire vise on the workbench. ^[1]

Bench vise

2. Rotary table vise: also known as rotary table vise and flexible table vise. The structure of this bench vise is basically the same as that of the fixed bench vise, except that there is an extra seat under the base, and the bench vise is fixed on the workbench by this seat. The vise can be rotated to any desired angle, and then the screw is tightened to fix the bench vise. When the shape of the workpiece is irregular or the workpiece is not suitable for processing in the direction of the vertical bench, use this bench The vice is more convenient. ^[1]

3, table roll-type bench vise: it is used to be called a table vise. The structure is basically similar to the fixed bench vise, except that it has a small vise body and a screw clamping device is made under the fixed vise body. This kind of bench vise is characterized by convenient installation, easy to carry and carry, and is mostly used in the occasions with large working fluidity and processing small workpieces. ^[1]

Vice vise hand vise

The hand vise is also called a hand-held vise and a hand vise. It is a hand-held tool designed for holding small workpieces or sheets for processing. When filing long and thin workpieces, it is necessary to clamp the workpiece with a vice and then place it on a bench vice for processing. It is also suitable for holding workpieces for welding and drilling.

Hand vise

There are two types of hand vise: ordinary and with handle. The common one is common on the market. The two clamping surfaces of the jaws of ordinary hand vise are not parallel, the tails of the two jaws are connected by pins, and there is a piece of spring in the middle of the two jaws so that the jaws are in an open state. The bolts are passed through the eyelets of the two pliers bodies and then connected with the wing nuts. The closing and opening of the two jaws is achieved by the wing nuts. ^[1]

The structure of a hand vise with a handle is slightly different from that of an ordinary hand vise. The handle is hollow to facilitate the work piece to pass through. There is no spring device in the middle of the two pliers, which is automatically opened by the elasticity of the round ends of the two pliers. The size of the opening of the two pliers is also adjusted by the wing nut. ^[1]

The specifications of the hand vise are expressed by the length of the jaw. The common specifications of the ordinary hand vise are 25 mm, 40 mm, and 50 mm. The common specifications of handle vise with handle are 6mm, 10mm and 15mm.

Vise pipe vise

Pipe bench vise is also called gantry rolling head, pipe pressure, pipe rolling, gantry bench vise. It consists of a base, a bracket, a pressure plate, a pull hook, a fixed jaw, a movable jaw, a screw, a wrench handle and other parts. It is a clamping tool specially designed for the device to tighten pipes or other cylindrical workpieces on the workbench for hinge threading or other processing. It is widely used in pipeline installation and pipeline maintenance. ^[1]

Pipe bench vise

Pipe bench vise can be divided into two types: fixed and movable according to different structures. The market is usually fixed.

The base of the fixed pipe bench vise is provided with eye holes for the screw to fix it on the workbench. In the middle of the base, two toothed blocks with V-notches are fastened with bolts, which are fixed jaws. One side of the bracket is fixedly connected with the base by a bolt, and the other side is movable, and the hook must be hooked on the base to be fixed. The screw rod can be rotated and moved up and down in the bracket. A wrench handle is inserted into the head of one end of the screw rod for operation, and the other end of the screw is embedded in the pressure plate. Both sides of the pressure plate can be moved up and down on the guide rail of the bracket. The lower part of the pressure plate also has a toothed plate with a V-shaped notch fastened with a screw. This is a movable jaw and is perpendicular to the center line of the fixed jaw. When the plate handle is rotated, the movable jaw moves up and down correspondingly with the screw rod and the pressure plate, and the distance moved is the opening size of the jaw. ^[1]

The structure of the movable pipe bench vise is basically the same as the fixed pipe bench vise, except that a screw clamping device is added below the base. The entire vise is fixed on the workbench by the flat block under the base, and the fixed screw is loosened To move the entire vise together.
