Clamp body

Abstract

The invention discloses a pliers body, which comprises a bottom plate, a fixed block, a movable block and a pushing device for pushing the movable block to move toward the fixed block. The bottom plate is strip-shaped, and the fixed block is fixed on the bottom plate. The pushing direction of the pushing device is along the length direction of the bottom plate, and both sides of the bottom plate are provided with chutes along the length direction of the bottom plate, and the movable block is provided with two pieces respectively matched with different chute Slider; each side of the base plate is provided with two slide grooves, and the two slide grooves on the same side of the base plate are respectively located at the upper end and the lower end of the base plate; Both devices are connected to the bottom plate in a detachable connection form. When the structure completes the clamping of parts, it is beneficial to the uniformity of force on each point on the clamping surface, and at the same time has a long service life.

Description

technical field [0001] The invention relates to the field of machining equipment, in particular to a pliers body. Background technique [0002] In the process of mechanical manufacturing, the device used to fix the processing object so that it occupies the correct position to accept construction or inspection is generally called a fixture, also known as a jig. In a broad sense, any process in the process of workpiece production, inspection or maintenance, the device used to quickly, conveniently and safely install the workpiece can be called a fixture. Such as welding fixtures, inspection fixtures, assembly fixtures, machine tool fixtures, etc. [0003] In the prior art, a bench vise is a kind of universal fixture, and is an indispensable clamping device on a fitter's bench. Although the bench vise can clamp larger workpieces and provide sufficient clamping force, for parts with high dimensional accuracy, the bench vise clamp During the holding time, the different positio...

AI Technical Summary

Problems solved by technology

[0004] In the above-mentioned prior art, for parts with high dimensional accuracy, when the parts are clamped by the bench vise without using other cushioning objects to wrap the parts, the force on the jaws of the bench vise is uneven at different positions. It is easy to cause the problem that the dimensional accuracy of parts is damaged, the invention provides a pliers body
