Abstract

The invention relates to a mechanical arm joint quick changing port, in particular to a mechanical arm joint quick changing port capable of being replaced on a track. The mechanical arm joint quick changing port aims at solving the problem that an existing large space mechanical arm cannot conduct maintenance on the track. The mechanical arm joint quick changing port comprises a convex body, a concave body matched with the convex body, a guiding mechanism, a positioning mechanism, an electric connector auxiliary connecting mechanism and six quick detaching and connecting mechanisms, wherein the positioning mechanism and the electric connector auxiliary connecting mechanism are installed on the concave body, the guiding mechanism is installed on the convex body, the six quick detaching and connecting mechanisms are evenly installed on the concave body, and the concave body is connected with the convex body through the six quick detaching and connecting mechanisms. The mechanical arm joint quick changing port is suitable for the aerospace field.

Description

technical field [0001] The invention relates to a quick-change interface of a mechanical arm joint, in particular to a quick-change interface of a mechanical arm joint that can be replaced on rail, and belongs to the field of aerospace. Background technique [0002] The large space robotic arm is an indispensable operating tool for the space station, which can minimize the high-risk and high-cost outbound operations of astronauts. The space manipulator is a supporting technology for on-orbit maintenance and construction. Through remote operation on the ground or autonomous operation of the manipulator, it can achieve precise positioning, grasp, transport, and replace objects, and realize orbit maintenance operations and space station assembly tasks. It can cooperate with astronauts to go out of the warehouse to carry out difficult maintenance tasks. Large space manipulators are characterized by high cost, complex structure and long-term on-orbit operation. At present, the ...
