Abstract
The utility model provides a kind of rotation looper piezoelectric micromotion motor, comprises piezoelectric stack, clamping institution, driving mechanism, base, rotor, stator base and axle.Stator base is fixed on base by the form of inlaying, and two driving mechanisms and two clamping institutions are distinguished symmetrical, and two symmetry axis are mutually vertical.The position of clamping institution and rotor contact adopts wedge structure, and rotor adopts side shaped upper portion flabellum shape structure.Not only structure is simple for this fine motion motor, location is reliable, and clamping institution and rotor contact forces adjustable.
Description
Technical field
The utility model relates to a kind of rotary piezoelectric fine motion motor, according to bionics looper principle, relies on piezoelectric stack as the fine motion motor driven.
Background technology
Existing looper piezoelectric motor comes with some shortcomings: activation configuration is complicated, size is larger; Adopt the driver of structure-integrated processing, single part structure is comparatively complicated, and between clamping institution and rotor, precision gap does not realize by regulating, and process and assemble difficulty is higher.Therefore, greatly limit the application of looper motor on fine motion precision actuation field.
Utility model content
For above-mentioned deficiency of the prior art, the utility model provides that a kind of structure is simple, size is less and between clamping institution and rotor, precision gap is adjustable rotation looper piezoelectric micromotion motor.
The technical solution of the utility model: rotate looper piezoelectric micromotion motor, comprise piezoelectric stack, clamping institution, driving mechanism, base, rotor, stator base and axle.It is characterized in that: rectangular stator base is installed to base inner surface by the form of inlaying.
Further technical scheme, two driving mechanisms are arranged symmetrically in above stator base, and driving mechanism is provided with the groove of dress piezoelectric pile near the position at axle center.Two clamping institutions are symmetrically arranged on driving mechanism, and two clamping institution symmetry axis are mutually vertical with the symmetry axis of two driving mechanisms.Two gaps between clamping institution and rotor change by regulating dog screw, and the position of clamping institution and rotor contact adopts wedge structure.
Further technical scheme, rotor side surface is thin-walled annular, and top is that four uniform flabellum thin slices are fixed on axle place.
Relative to prior art, the utility model has following beneficial effect:
Rotate each design of part of looper piezoelectric micromotion motor simple, between part, location is reliable and convenient.The wedge structure at clamping institution and rotor contact place can adjust the maximum unilateral force between clamping institution and rotor.
