Embodiment Construction
[0018] The detailed content of the present invention and its specific implementation will be further described below in conjunction with the accompanying drawings.
[0019] see Figure 1 to Figure 3 As shown, in the inchworm-type rotary piezoelectric drive platform of the present invention, the rotor unit is a cylinder for outputting rotational displacement; the upper clamping unit consists of a piezoelectric stack, an upper stator, an upper bridge-type flexible hinge amplification structure, and an upper lever It is composed of flexible hinge amplifying structure and pre-tightening bolts. When the piezoelectric stack is extended, the upper layer of the stator can clamp the rotor; the lower clamping unit has the same structure as the upper clamping unit. The flexible hinge amplifying structure, the lower lever type flexible hinge amplifying structure and pre-tightening bolts, when the piezoelectric stack stretches, the lower layer of the stator can clamp the rotor; the driving...
