Abstract

A robot arm joint quick-change interface system allowing on-rail replacement relates to a robot arm joint quick-change interface system. The robot arm joint quick-change interface system solves the problem that an electric connector of a conventional robot arm joint quick-change interface system is damaged due to overload, since the electric connector has no over travel buffering function. A tolerance guiding abutting apparatus comprises a recessed body and a protruding body matching with the recessed body structure, wherein the recessed body and the protruding body are detachably connected through a plurality sets of locking positioners and a plurality sets of mechanical connection and quick-detach apparatuses, the plurality sets of locking positioners are uniformly arranged between the recessed body and the protruding body, and the plurality sets of mechanical connection and quick-detach apparatuses are uniformly arranged between the recessed body and the protruding body. An electrical connecting device is arranged in a cavity formed by the recessed body and the protruding body. The robot arm joint quick-change interface system is used for spatial on-rail maintenance.

Description

technical field [0001] The invention specifically relates to an on-rail replaceable mechanical arm joint quick-change interface system. Background technique [0002] The large-scale space manipulator is the core equipment for space on-orbit maintenance. It has the characteristics of complex structure, high cost, high launch cost, and long on-orbit operation time. At present, the large-scale space manipulators in orbit in the world include the Canadian space station teleoperated manipulator SSRMS and the Japanese experimental module manipulator JEMRMS. Both of these two manipulators are designed to be maintained and replaced on orbit. In order to reduce the maintenance cost of the manipulator, the key to on-orbit maintenance of the manipulator is to replace the failed joint module, so the joint quick-change interface is designed to facilitate rapid replacement and maintenance by astronauts. [0003] The joint quick change interface needs to ensure the rigid connection of the...
