Abstract

The invention is mainly applied to clamping of precise workpieces of lathes in mechanical machining, and particularly relates to a damage-proof clamp for a lathe chuck. The damage-proof clamp comprises clamping jaw assemblies, wherein each clamping jaw assembly comprises a fixing sleeve, the fixing sleeve is a rectangular hollow clamping sleeve, the inner end of the fixing sleeve is fixedly connected with an arc-shaped adjusting spring piece, the outer end of the fixing sleeve is provided with a pressing bolt, and the inner side face of the fixing sleeve is provided with a rubber wear-resistant layer. According to the design of the damage-proof clamp, the contact area is increased, so that the friction factor is increased, the clamping force is properly reduced, the clamping requirement ismet, and the damage to the workpiece is avoided.

Description

technical field [0001] The invention relates to an anti-pinch fixture for a lathe chuck, which is mainly used for clamping precision workpieces on a lathe during mechanical processing. Background technique [0002] During the turning process, when the three-jaw (four-jaw) chuck of the lathe clamps the workpiece, because the contact area is too small and the clamping force is too large, it is easy to cause damage to the surface of the workpiece, especially for precision workpieces, which directly affects the quality of the parts. Accuracy and surface quality, even lead to part scrapping. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an anti-pinch fixture for lathe chucks which solves the problem of excessive clamping force of the original chuck, causing damage to the surface of the workpiece or even scrapping the workpiece, and improves work efficiency. [0004] The lathe chuck anti-pinch fixture according to t...
