Fixture for machining

Abstract

The invention discloses a fixture for machining. The fixture comprises a bottom plate, a fixed clamping block, a movable clamping block and a pushing device for pushing the movable clamping block to move to one side of the fixed clamping block, wherein the bottom plate is bar-shaped; the fixed clamping block is fixed to one end of the bottom plate; the pushing direction of the pushing device is in the length direction of the bottom plate; sliding grooves in the length direction of the bottom plate are respectively formed in two sides of the bottom plate; two sliding blocks respectively matched with different sliding grooves are arranged on the movable clamping block. According to the fixture, when clamping parts and components is completed, uniform stressing of each point on a clamping surface is facilitated.

Description

technical field [0001] The invention relates to the field of machining equipment, in particular to a jig for machining. 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 p...

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 fixture for machining
