一、前言在气动夹具中,夹紧力的传递有两种方法:(1)直接从活塞杆传给夹紧元件(图一);(2)间接从活塞杆经过增力机构再传给夹紧元件。直接传递的方法常用于夹紧力要求不大时；或者需要大的夹紧力而允许增大气刚直径时。但这时不要 I. Introduction In the pneumatic clamp, the clamping force is transmitted in two ways: (1) directly from the piston rod to the clamping element (Figure 1); (2) indirectly from the piston rod through the force-transmitting mechanism and then to the clamp Tight components. The method of direct delivery is often used when the clamping force is less demanding, or when large clamping force is required to increase the air-to-air diameter. But this time do not
