Robot joint vibration reduction device and robot

Abstract

The invention relates to a robot joint vibration reduction device and a robot. The robot joint vibration reduction device comprises a shell, a core body and a vibration reduction assembly; the shell is allocated to be annular, containing cavities are formed between the inner wall and the outer wall of the shell, a containing groove is formed in one side of each containing cavity in the circumferential direction of the shell, and the containing grooves are formed in the inner wall of the shell; the core body comprises core blocks and stop blocks, the core blocks are rotatably arranged at the inner side of the shell, and the stop blocks are arranged on the core blocks and inserted into the containing grooves; the vibration reduction assembly comprises pistons, piston rods, intelligent materials and elastic pieces; the pistons are arranged in the containing grooves; the first ends of the piston rods are arranged in the containing cavities and connected with the pistons, and the second ends of the piston rods penetrate through the side walls of the containing cavities, are arranged in the containing grooves and connected with the stop blocks; the containing grooves are filled with theintelligent materials; and the elastic pieces are arranged in the containing grooves and abut against the side walls of the containing cavities and the stop blocks. According to the embodiment of therobot joint vibration reduction device, the vibration generated when the robot operates can be attenuated in real time in a manner of combining the intelligent materials and the elastic pieces, and abetter buffering effect on the vibration is achieved.

Description

technical field [0001] The invention relates to the field of robots, in particular to a robot joint vibration damping device and a robot. Background technique [0002] The status of robots in modern society is becoming more and more important, especially industrial robots, which play an irreplaceable role in industrial production. With the improvement of production efficiency, higher and higher operating speeds of industrial robots are also proposed. Fast requirements, but when the robot speed reaches a certain level, it will produce different degrees of vibration, especially when the robot accelerates and decelerates rapidly, and even when it runs to the soft limit, it will produce different degrees of impact. Excessive vibration not only reduces the running accuracy, but also seriously affects the overall performance, and even greatly shortens the use of parts. Contents of the invention [0003] Some embodiments of the present invention provide a robot joint vibration d...

[0002] The status of robots in modern society is becoming more and more important, especially industrial robots, which play an irreplaceable role in industrial production. With the improvement of production efficiency, higher and higher operating speeds of industrial robots are also proposed. Fast requirements, but when the speed of the robot reaches a certain level, it will produce different degrees of vibration, especially during rapid acceleration and deceleration, and even when it runs to the soft limit, it will produce different degrees of impact

Excessive vibration will not only reduce the running accuracy, but also seriously affect the overall performance, and even greatly shorten the use of parts
