Abstract

The invention discloses a planar two-degree-of-freedom ultrasonic motor structure, which relates to the field of electromechanical technology. The motor structure includes: a motor housing, the inside of the motor housing is provided with an installation cavity, and one side of the motor housing is provided with an installation port that communicates with the installation cavity, and is connected to the installation cavity. The side of the motor housing opposite to the installation port is provided with an output port that communicates with the installation cavity; the output part, one end of the output part penetrates and extends out of the output port, and the other end of the output part is connected to an elastic body ; The elastic body, the bottom of the elastic body is connected with a friction material layer, the elastic body, the bottom of the elastic body is connected with a friction material layer, and the top of the elastic body is connected with a piezoelectric ceramic layer; the plane double degree of freedom described in this patent The ultrasonic motor expands the output form of the ultrasonic motor, can effectively increase the application field of the ultrasonic motor, and has a compact structure and simple process, which is convenient for market promotion and industrial production.

Description

technical field [0001] The invention relates to the field of electromechanical technology, and can be used in the fields of optical instruments, detection systems, precision machining, weapons and military industry, and more specifically relates to a planar double-degree-of-freedom ultrasonic motor structure. Background technique [0002] Ultrasonic motor is a kind of drive that uses mechanical vibration in the ultrasonic frequency domain as the driving source. It has the characteristics of low speed and high efficiency, compact structure, self-locking when power is off, and no electromagnetic interference. In recent years, with the acceleration of the development of intelligent weapons at home and abroad, the application of ultrasonic motors in the field of weapons has attracted more and more attention. At present, the common ultrasonic motors on the market mainly have two structural modes, one is a linear motor with single-degree-of-freedom motion, and the other is a rotar...
