Three-degree-of-freedom parallel flexible micro-motion platform

The utility model provides a three-degree-of-freedom parallel flexible micro-motion platform, which comprises an actuating mechanism, a piezoelectric ceramic driver, a first flexible guide mechanism, a second flexible guide mechanism, a movable platform, a micro-motion platform frame and a pre-tightening nail, and is characterized in that the piezoelectric ceramic driver drives the actuating mechanism and the second flexible guide mechanism to translate in the X direction; reversing or transmission of a pair of displacements of the flexible guide mechanism can be controlled by adjusting the direction of input displacements, translational motion of the movable platform in the X direction and rotation around the Z axis can be achieved, and the whole device is compact in structure and has three degrees of freedom of translation in the X direction and the Y direction and rotation around the Z axis. The three-degree-of-freedom parallel mechanism is compact in structure, has three degrees of freedom of translation
