Abstract

The invention discloses a caliper body, which comprises a bottom plate, a fixed clamping block, a movable clamping block and a push device used for pushing the movable clamping block to move to one side of the fixed clamping block. The bottom late is of a strip shape; the fixed clamping block is fixed at one end of the bottom plate; the push direction of the push device is along the length direction of the bottom plate; two sides of the bottom plate are both provided with chutes along the length direction of the bottom plate; the movable clamping block is provided with two sliding blocks respectively matched with different chutes; each side of the bottom plate is provided with two chutes, and the two chutes located in the same side of the bottom plate are respectively positioned at the upper end and the lower end of the bottom plate; the upper end and the lower end of the bottom plate are unequal in width, and the connection modes of the fixed clamping block and the push device with the bottom plate are both detachable connection forms. The structure is beneficial to the homogeneity of stress of all points on a clamped surface during finishing clamping of parts, and at the same time the service life is long.

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...

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
