Abstract

The invention belongs to a bionic piezoelectric foot type driver and belongs to the field of micro-mechanical and electronic engineering. Two driver driving feet are symmetrically arranged at two ends of a driver body, and each driving foot of the driver consists of a metal substrate, two first piezoelectric ceramic wafers, two second piezoelectric ceramic wafers and a cylindrical friction block. The metal substrate consists of a cross beam and a vertical beam, wherein one end of the cross beam of the metal substrate is fixedly connected onto the driver body through a screw, the two first piezoelectric ceramic wafers are symmetrically bonded on the upper and lower faces of the cross beam of the metal substrate, the two second piezoelectric ceramic wafers are symmetrically bonded on the left and right faces of the vertical beam of the metal substrate, and one end of the vertical beam of the metal substrate is fixedly connected with the cylindrical friction block. The bionic piezoelectric foot type driver has the advantages that the driving feet of the driver can imitate leg actions of walking animals, the driver is novel in structure, large in stroke and simple in structure, and a control system is simple.

Description

technical field [0001] The invention belongs to the field of micromechanical and electronic engineering, and in particular relates to a piezoelectric foot driver. Background technique [0002] With the development of science and technology, nanotechnology plays an increasingly important role in the mechanical field. The research on the micro-displacement system has attracted the attention of scholars at home and abroad, and various micro-drivers with functions of precise driving, precise measurement and precise positioning have been developed successively. Because piezoelectric elements have the characteristics of small size, high displacement resolution, fast frequency response, no electromagnetic interference, and no noise, piezoelectric micro-actuators using such elements as driving sources have attracted more and more attention. [0003] The currently developed micro-drivers using piezoelectric elements as the driving source are mainly divided into the following fou...
