Macro and micro drive rotary platform based on bionical feeler and thermal energy

The utility model relates to a macro and micro drive rotary platform based on bionical feeler and thermal energy belongs to the ultra -precision driving field. Macroscopic view piezoelectricity drive unit carries out clockwise macroscopical drive through the elastic deformation of flexible hinge of interior envelope formula and bionical wedge feeler to the cylindricality rotor respectively, and microcosmic thermal energy drive unit passes through the heat -conduction of high temperature ceramic heating rod and locates to produce controllable hot expansion deformation at the intermittent type of bionical wedge feeler, and then the small linear displacement of drive feeler production, realizes driving the microcosmic of cylindricality rotor. The cylindricality rotor is embedded in the rotor of ceramic ball bearing with the interference fit mode, and the embedded rigidity plane reflector panel of installing in its recess for non -contact optics displacement measurement system is to the rotatory quantitative determination who is out of shape of cylindricality rotor. The advantage lies in: compact structure, can satisfy receive a little the operation, receive fields such as processing, precision optics, space flight and medical engineering to the demand of micro -nano level ultra -precision driving with the location a little.
