摘要

Recently, high-precision positioning is increasingly required in precision manufacturing, measuring instrument and so on. The purpose of this study is to develop a new type mechanism which is capable of fine positioning with five DOF, high rigidity and heavy load capability. It consists of three plates and six piezoelectric actuators. Each actuator has a flexible end which is deformed and inclined to perform the motions of X,Y,Z, α and β with controlled piezo expansion. Since this mechanism has neither guide way nor lubrication, it is operated without friction, wear and backlash.
