摘　　要：在重型车床工件装卡过程中,卡爪卡紧力的大小对工件的定位影响极为重要。如何在有限的空间内,设计出具有更大卡紧力和高保持性的卡爪,同时降低操作者的劳动强度,是设计者备受关注的重要问题。本文推荐一种新型的双腔液压增力卡爪,可同时实现内外卡紧功能,大大提高卡爪的保持性。The clamping force of claws is very important to the positioning of the work-piece during the loading process of heavy lathe. It is the most important point that how to design the claws with greater clamping force and high security and reduce the labor intensity of the operator in limited space. In this paper, we introduce a new type of double cavity hydraulic pressure card claw which can realize the function of bidirectional clamping, and improve the greatly retention.
