Component fixing device

Abstract

The invention discloses a component fixing device, which comprises a bottom plate, a fixed block, a movable block and a pushing device. The bottom plate is strip-shaped, and the fixed block is fixed at one end of the bottom plate. The chute in the direction of the chute, the movable block is provided with two sliders that cooperate with different chute respectively, the mating surface formed by the side of the chute and the bottom surface of the slider is an arc surface, and in the depth direction of the chute, the arc The highest point of the shape surface is located between the opening end of the chute and the bottom end of the chute; two chutes are provided on each side of the bottom plate, and the two chute on the same side of the bottom plate are respectively located at the upper end and the lower end of the bottom plate ; The width of the upper end and the lower end of the bottom plate is not equal, and the connection mode between the fixed block and the pushing device and the bottom plate is a detachable connection form. When the parts are clamped, the structure is beneficial to the uniformity of the force on each point on the clamping surface; it is beneficial to the stability of the relative positions of the fixed clamping block and the movable clamping block, and has a long service life.

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
