Abstract

A fast clamping mechanism for sheet part is composed of supporter, connecting screw, connecting plate, handle connecting screw, pressing plate and universal joint bearing arranged in the central hole of pressing plate. Its advantage is high pressure uniformity.

Description

technical field [0001] The invention relates to a quick clamping mechanism, in particular to a quick clamping mechanism for clamping thin plate parts. Used in the field of mechanical engineering. Background technique [0002] Historically, the shape of the final force-applying part of various clamping mechanisms is a block structure. In design calculations and other applications, the applied force of the block-shaped force-applying part is usually simplified to a point, referred to as a point pressure head. . In the practical application of welding test, it is necessary to clamp thin metal test plate and in the practical application of welding production, it is necessary to clamp thin metal stamping parts. If a point pressure head is used, only the welding deformation around the stress point is controllable. Usually there will be a large welding deformation in the remaining part. Due to manufacturing errors, the surface of the thin metal plate assembly and the surface of ...
