Abstract

The invention relates to a staggered four-foot driving piezoelectric stepping linear motor. A first actuating rod and a second actuating rod are symmetrically distributed relative to a rotor, one end of the first actuating rod is connected with a left upper base through a left horizontal flexible hinge, and one end of the second actuating rod is connected with a right upper base through a right horizontal flexible hinge. The other end of the first actuating rod is connected with the first clamping mechanism in a matched mode, and the other end of the second actuating rod is connected with the second clamping mechanism in a matched mode. According to the staggered four-foot driving piezoelectric stepping linear motor, the telescopic effect of laminated piezoelectric ceramics is transmitted to a rotor through a swing rod and a displacement conversion mechanism, and the displacement output direction is parallel to the telescopic direction of the laminated piezoelectric ceramics; and when a piezoelectric control signal is input to the laminated piezoelectric ceramic, differential action can be realized, so that large stroke, large thrust and high precision are taken into consideration.

Description

technical field [0001] The invention relates to the technical field of piezoelectric precision actuation, in particular to an interleaved quadruped-driven piezoelectric stepping linear motor. Background technique [0002] Piezoelectric motors are a type of energy conversion device that converts alternating electrical signals into vibrations of motor-driven feet through the inverse piezoelectric effect of piezoelectric materials, and then converts micro-vibrations into motions of motor movers or rotors through friction. According to the vibration state of the piezoelectric motor stator, it is divided into two types: resonance (ultrasonic motor) and non-resonance. Non-resonance piezoelectric motors include inertial type, inchworm type, and differential type according to the operating mode. Among them, the performance parameters of the inertial piezoelectric motor change when the load changes, which is suitable for occasions where the load is constant or changes little; the inc...
