Problems solved by technology

[0003] When the traditional arc-shaped or diamond-shaped fixed jaw clamps are used for clamping operations, they can only adapt to circular connectors within a certain diameter range. For connectors smaller than their minimum clamping diameter, fillers can only be used to fill the gaps. Decrease the stability of clamping and affect the assembly efficiency at the same time

Abstract

The invention provides a clamp which is used for clamping a round workpiece and comprises a clamp frame, an upper fork clamp and a lower fork clamp. The clamp frame is of a frame structure and surrounds the upper fork clamp and the lower fork clamp. One end of the upper fork clamp is connected with the clamp frame, and an upper V-shaped claw is fixed at the other end of the upper fork clamp; one end of the lower fork clamp is connected with the clamp frame, and a lower V-shaped claw is fixed at the other end of the lower fork clamp; the upper V-shaped claw and the lower V-shaped claw are oppositely arranged to form a rhombic area for clamping the cylindrical surface of the workpiece; and the rhombic area is defined by four planes facing the workpiece in sequence, and the size of the rhombic area can be adjusted. By means of the clamp, by adjusting the size of the rhombic area, the clamp can adapt to workpieces with large-range diameter changes, and the cost is reduced; and the structure is simple and stable, and efficiency is improved.

Description

technical field [0001] The invention relates to the field of workpiece clamping equipment, in particular to clamps. Background technique [0002] Many circular parts and equipment need to be clamped, such as circular connectors. Circular connectors are commonly used connector types in the military and aerospace fields. When welding and binding circular connectors, etc., it is necessary to fix the connectors with clamps so that the assemblers can operate with their hands free. Get a stable operating environment. [0003] When the traditional arc-shaped or diamond-shaped fixed jaw clamps are used for clamping operations, they can only adapt to circular connectors within a certain diameter range. For connectors smaller than their minimum clamping diameter, fillers can only be used to fill the gaps. The stability of the clamping is reduced, and the assembly efficiency is affected at the same time. [0004] Based on the above problems, there is an urgent need for a fixture tha...
