Robot joint vibration damping device and robot

Abstract

The invention relates to a robot joint vibration damping device and a robot. Wherein, the robot joint vibration damping device includes: a housing, which is configured as a ring, and an accommodation cavity is provided between the inner wall and the outer wall of the housing. Along the circumferential direction of the housing, one side of the accommodation cavity is provided with an accommodation groove. The inner wall of the shell; the core body, including a core block and a stopper, the core block is rotatably arranged on the inside of the shell, the stopper is arranged on the core block, and is inserted into the receiving groove; and a vibration damping assembly, which includes : the piston is arranged in the accommodation cavity; the piston rod is arranged in the accommodation cavity at the first end and connected to the piston, and the second end passes through the side wall of the accommodation cavity and is arranged in the accommodation groove and is connected with the stopper; the smart material, filling in the accommodating cavity; and the elastic member is arranged in the accommodating groove and abuts against the side wall of the accommodating cavity and the stopper. The embodiment of the present invention can attenuate the vibration generated during the operation of the robot in real time through the combination of the intelligent material and the elastic member, and has a good buffering effect on the vibration.

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.
