Fixing device for part

Abstract

The invention discloses a fixing device for a part. The fixing device comprises a bottom plate, a fixed clamping block, a movable clamping block and a pushing device, wherein the bottom plate is strip-shaped; the fixed clamping block is fixed at one end of the bottom plate; sliding grooves are formed in the two sides of the bottom plate in the length direction of the bottom plate; two sliding blocks respectively matched with the different sliding grooves are arranged on the movable clamping block; matching surfaces formed by the side surfaces of the sliding grooves and the bottom surfaces of the sliding blocks are arc-shaped surfaces; in the depth directions of the sliding grooves, the highest position points of the arc-shaped surfaces are positioned between the opening ends of the sliding grooves and the bottom ends of the sliding grooves; two sliding grooves are formed in each side of the bottom plate; the two sliding grooves positioned on the same side of the bottom plate are respectively positioned at the upper end and the lower end of the bottom plate; the widths of the upper end and the lower end of the bottom plate are not equal; and the fixed clamping block and the pushing device are detachably connected with the bottom plate. According to the fixing device, when the part is clamped, the uniformity of stress of all points on a clamping surface is facilitated, and the stability of the relative position of the fixed clamping block and the movable clamping block is facilitated; and the service life is long.

Description

technical field [0001] The invention relates to the field of mechanical processing equipment, in particular to a component fixing device. 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 tim...

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 the parts is damaged, the invention provides a part fixing device
