众所周知 ,螺旋夹紧机构是应用最广的一种夹紧机构 ,它主要是利用螺纹直接夹紧工件 ,或者是与其他元件或机构组成复合夹紧机构来夹紧工件。螺旋夹紧机构具有结构简单、制造容易、夹紧可靠、增力比大、行程不受限制等优点。但同时也具有夹紧动作慢、辅助时间长、效率低等缺点 ,?
As we all know, spiral clamping mechanism is the most widely used a clamping mechanism, which is mainly used to directly clamp the workpiece thread, or with other components or mechanisms to form a complex clamping mechanism to clamp the workpiece. Helical clamping mechanism has the advantages of simple structure, easy manufacture, reliable clamping, large power ratio and unlimited travel. But at the same time also has a slow clamping action, aids a long time, low efficiency and other shortcomings,?
