Abstract

The invention provides a stepping type piezoelectric actuator and a robot. The stepping type piezoelectric actuator comprises an actuator shell, a stepping type piezoelectric stack, a displacement amplifier, a clamping mechanism and an output shaft, wherein the stepping type piezoelectric stack is fixed to the actuator shell; the displacement amplifier is connected with the stepping piezoelectric stack; the clamping mechanism is connected with the displacement amplifier; the output shaft is connected with the clamping mechanism; and the stepping piezoelectric stack pushes the displacement amplifier to move, the displacement amplifier pushes the clamping mechanism to move after amplifying displacement, and the clamping mechanism pushes the output shaft to move. According to the stepping type piezoelectric actuator, the displacement of the stepping piezoelectric stack is amplified to the displacement requirement of the robot through the amplifier, the movement speed, the resolution, the response speed and other characteristics of the robot can be improved, and the robot has the advantage of being free of electromagnetic interference; and the stepping type piezoelectric actuator has potential application prospects in the fields of precision detection and transportation in extreme environments such as nuclear radiation and electromagnetic interference.

Description

technical field [0001] The application belongs to the technical field of robots, and in particular relates to a stepping piezoelectric driver and a robot. Background technique [0002] With the continuous progress of human society, the development of robots has also entered the fast lane. Robots have played a major role in improving human production efficiency and reducing human exposure to polluted environments. At present, if the motion displacement requirements of the robot are met, the motor cannot be used, but this makes the robot unable to go to the heavy magnetic field area and the nuclear pollution area; if the robot's requirements for the use environment are met, the motion displacement cannot be satisfied. Contents of the invention [0003] Embodiments of the present application provide a stepping piezoelectric driver and a robot to solve the problem of high displacement requirements of existing robots in complex environments. [0004] In the first aspect, the e...
