Abstract

The invention relates to a micro-nano simulation rotating drive device, which belongs to the precise and super-precise machining field. The micro-nano simulation rotating drive device mainly consists of a stator and a rotor, wherein a drive piezoelectric stack is encapsulated inside the stator; and the rotor is a variable-type interface shaft. A high-precision piezoelectric drive device is used for driving a lever amplification flexible hinge structure to perform associated clamping, and the stepper super-precision rotation movement for the rotor to rotate along a fixed shaft is realized by controlling the clamping sequence of a piezoelectric clamping mechanism in the stator. The micro-nano simulation rotating drive device can be used for the high-precision drive and machining field, and has advantages of less investment, low cost, fast effect, high benefit and the like. The micro-nano simulation rotating drive device is a piezoelectric single-degree-of-freedom precision rotating drive device which can improve the system micro precision and reduce the structural size and can make super-precision stepper rotation movement along a determined direction.
