Clamping tool favorable for uniform distribution of clamping force

Abstract

The invention discloses a clamping tool which is beneficial to the uniformity of the clamping force distribution, comprising a base plate, a fixed block, a movable block and a pushing device for pushing the movable block to move toward the side of the fixed block, the bottom plate is strip-shaped , the fixed block is fixed on one end of the bottom plate, the pushing direction of the pushing device is along the length direction of the bottom plate, both sides of the bottom plate are provided with chute along the length direction of the bottom plate, and the movable block is provided with Two sliders that are matched 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 highest point of the arc surface is at Between the open end of the chute and the bottom end of the chute. When the parts are clamped, the structure is beneficial to the uniformity of force on each point on the clamping surface and to the stability of the relative positions of the fixed clamping block and the movable clamping block.

Description

technical field [0001] The invention relates to the field of mechanical processing equipment, in particular to a clamping tool that facilitates the uniform distribution of clamping force. 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 accu...

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 clamping tool that is beneficial to the uniformity of the clamping force distribution
