Summary: | The utility model provides a novel three-degree-of-freedom positioning platform driven by a piezoelectric actuator based on a flexible hinge, which comprises a novel four-steady-state mechanism, a novel bridge type amplifying mechanism, a double-rocker mechanism, a motion reverse compensation mechanism, a bridge type amplifying mechanism, a central micro-motion platform, a piezoelectric actuator, a fixed end and a positioning hole, the piezoelectric actuator drives the novel bridge type amplification mechanism and the novel four-stable-state mechanism to generate X-direction translation, and the piezoelectric actuator drives the bridge type amplification mechanism, the motion reverse compensation mechanism and the double-rocker mechanism to generate Y-direction translation and rotate around the Z axis. By adjusting the number of the piezoelectric actuators and the direction of input displacement, translation of the center micro-motion platform in the X direction and the Y direction and rotation around the Z a |
