Abstract

The invention discloses an actuator based on the inverse piezoelectric effect, which comprises a base, a stator arranged on the base, and a mover arranged on the base and connected to the stator, and a positioning device is arranged between the base and the stator , and the stator is arranged on the base through a positioning device, the stator includes a stator bottom plate, an amplifying unit structure arranged on the stator bottom plate, and a power device connected to the amplifying unit structure in transmission, and the power device can push the amplifying unit structure to move, and through The amplifying unit structure drives the mover to move; the beneficial effect of the present invention is that the stator adopts the piezoelectric stack as the power device, which can realize micro-displacement action, and the use of the piezoelectric stack can increase the driving displacement of the piezoelectric ceramics, and at the same time has a low The advantages of power consumption, fast response and low heat generation.

Description

technical field [0001] The invention relates to the technical field of micro-displacement driving devices, in particular to an actuator based on the inverse piezoelectric effect. Background technique [0002] In recent years, with the continuous development and progress of science and technology, various new technologies have emerged, especially in aerospace, bionic technology, precision machinery, medicine, artificial satellites and other fields, which require high positioning capabilities. Moreover, with the diversification of machine working environments and applications, not only the actuators are required to have micron to nanometer high precision and precise motion control requirements, but also the actuators are expected to be miniaturized, lightweight and modularized. And it can be used safely in special occasions, such as electromagnetic field environment. Since most traditional actuators use electrothermal, electromagnetic or mechanical driving methods, for the re...
