摘　　要：设计了一种无杆双活塞气缸与浮动式杠杆-铰杆-斜楔机构复合的三向夹紧系统,分析了系统的结构和工作原理,并给出力学计算公式。由于在无杆活塞中采用有自位作用的浮动块结构,使得夹紧力输出传动链在实现力放大的同时,又可以自动补偿各路输出的行程误差。系统中所采用的双平行杠杆高副传力方式,使得单侧两路输出传动链自成体系,互不干扰,不仅实现了三向夹紧,而且可以通过调整增力机构的参数,实现水平方向和铅垂方向夹紧力大小的调整。Designed a three-direction clamping system consisting of a rodless double-piston cylinder and a floating lever- hinge rod- wedge ramp mechanism, analyzing the structure and working principle, as well as introducing the mechanics formula. Because of the application of the self-positioned floating module in the rodless piston, the clamping system can increase the force while adjusting the process errors. The way that a double-parallel lever transmitting force used in this system had made the two transmission chain in one side independently so that it can be clamped in the three directions. Meanwhile it can adjust the force in the horizontal and vertical directions by changing the parameters of the force amplifying mechanism.
