Title:
INDUSTRIAL ROBOT JOINT ACTIVE DAMPING DEVICE AND DAMPING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2022/241905
Kind Code:
A1
Abstract:
The present invention relates to the field of industrial robots, and particularly relates to an industrial robot joint active damping device. For the problems that although an existing active damping device consisting of an outer ring, an inner ring, a metal rubber and the like can also have a damping function when a robot joint is driven, the real-time damping effect is relatively poor, vibration cannot be rapidly attenuated, and the vibration buffering effect is not good, the following solution is now provided. The device comprises a housing; a supporting base is fixedly mounted at the top of the housing; a sliding base is slidably mounted at the top of the housing; a mounting plate is fixedly mounted at the top of the sliding base; the top of the mounting plate penetrates through the inner wall of the top of the housing and the top of the supporting base and extends above the supporting base; a longitudinal damper is fixedly mounted on the inner wall of the bottom of the housing. In the present invention, an accurate active damping force can be generated, the vibration generated during joint operation of an industrial robot can be rapidly attenuated, and the vibration buffering effect is good.
