Piezoelectric drive mechanism

Abstract

Abstract PURPOSE:To improve the drive efficiency of a clamping body by extending and moving a clamping drive section by longitudinal-effect strain and shifting the relative position of a tongue section along a shaft in the direction of the nose coupling section for a sliding section. CONSTITUTION:A clamping body 12 has a clamping drive section 121 with a shaft in the same direction as a shaft 91, a sliding section 124 and a tongue section 125. The noses of the sliding section 124 and the tongue section 125 are coupled by a nose coupling section 126. When the clamping drive section 121 is extended by applying voltage, the tongue section 125 extrudes the nose coupling section 126 through a piezoelectric element holding section 123. The two clamping bodies 12 are driven alternately and repeat holding and release, a shaft driver 93 repeats expansion and contraction, and a relative position between the shaft driver 93 and the shaft 91 is moved in a stepped manner.
