Abstract

The invention relates to a space robot orbit tool replacing device, which belongs to the field of space robot on-orbit service and aims at solving the problems that the existing orbit tool replacing device has poor space operation reliability, the great pose tolerance can not be realized, the power consumption is high, the mass is high, and the like. For the mechanical transmission, a motor of a first set of driving system is used for driving a gear, a transmission shaft is driven by the gear, in addition, the function is realized through the butt joint of a screw bolt sleeve arranged on the transmission shaft and a screw bolt head arranged at the other end of the transmission shaft. For electric transmission, a motor of a second set of driving system is used for driving the gear, a cam long shaft is driven by the gear, in addition, the moment on the cam long shaft is transferred to a cam short shaft through a steel wire, and two parts of an electric connector are in butt joint through a slider-crank mechanism fixedly arranged on the cam long shaft and the cam short shaft. The tool end locking adopts the kinematics coupling mode, and before the butt joint realization of the electric connector, a locking finger is driven by a cam to realize the locking of the tool end. The butt joint surface of the orbit tool replacing device and a replaceable tail end manipulator is a conical surface, and great pose tolerance capability can be realized.

Description

technical field [0001] The invention relates to a space robot track tool changer, which belongs to the field of space robot on-orbit service. Background technique [0002] With the advancement of technology, human activities are constantly expanding into space. According to statistics, an average of 80 to 130 satellites are launched each year in the world, but 2 to 3 satellites fail to be put into orbit correctly, and 5 to 10 of the satellites that are put into orbit correctly fail at the beginning of their life, which leads to huge economic loss. In order to recover losses as much as possible, various countries are researching space robot on-orbit service technology for the purpose of satellite maintenance, life extension and space junk removal by means of space robots. [0003] However, the complexity of space operations determines that a single end tool cannot complete all on-orbit tasks. Therefore, it is necessary to develop a multi-tool system to adapt to different ta...
