Abstract

The invention relates to a piezoelectric-electromagnetic hybrid driving multi-degree-of-freedom precision positioning device and a control method, and belongs to the field of precision machinery and precision engineering. A piezoelectric inertial rotary positioning assembly is fixedly mounted in a connecting sleeve and ensures a clearance fit with an output shaft in the case of power outage. A piezoelectric bimorph rotary positioning assembly is installed in an interference fit with the output shaft. The output shaft is supported and guided by bearings I and II fixedly mounted in the connecting sleeve to ensure that the axis of a connecting assembly at the tail end of the output shaft is coaxial with an output axis. A clamping mechanism is fixedly connected to the flange of a body by a connecting bolt, is in close contact with the connecting sleeve by using a hemispherical contact member to realize self-locking, and is fixed to an external macro-adjustment positioning platform throughthe end portion of the body. The piezoelectric-electromagnetic hybrid driving multi-degree-of-freedom precision positioning device has compact structure, can achieve axial large-stroke linear positioning and macro-micro hybrid rotational positioning, can realize multi-degree-of-freedom motion output, and has good application prospects in the fields of precision optics, micromanipulation, aerospaceand precision instruments.
