Abstract

The invention discloses an actuator based on the principle of multi-stage amplification, which includes a base, a stator arranged on the base and a mover arranged on the base and in contact with the stator, the bottom of the stator is provided with a positioning pad, the The stator is fixed on the base through a positioning backing plate, the mover includes a mover base, and a mover body cooperatingly arranged on the mover base, a slide rail is arranged on the mover base, and the mover body and the slide The rails are matched together, and the mover body is driven to move relative to the mover base under the action of the stator; 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 Improve the driving displacement of piezoelectric ceramics, and at the same time have the advantages of low power consumption, fast response and low heat generation.

Description

technical field [0001] The invention relates to the technical field of electronic micro-drive devices, in particular to an actuator based on the principle of multi-stage amplification. 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 ...
