摘　　要：采用摩擦驱动工作原理设计了大行程、高分辨率的步进式进给机构,该机构是压电陶瓷驱动的、滚珠丝杠传动并结合空气静压导轨实现微量进给;采用柔性4杆机构设计了压电陶瓷驱动的可调式预压装置;用有限元方法分析了柔性铰链的静态特性;对微进给机构的传动特性进行了详尽分析。based on friction driving principle, designed a long stroke length and high resolution walking micro - feeding device that is driven by piezoelectric ceramic elements and combined with the screw shaft and aerostatic guide way. The adjustable preloading device driven by piezoelectric was designed by using flexible four - bar linkage. The static properties of the flexible linkage device are analyzed with FEM. The transmission characteristics of the micro - feeding device are exhaustively analyzed.
