Abstract

The invention provides an end effector capable of achieving space manipulator self crawling and load operation, and relates to the end effector for a manipulator. The end effector capable of achieving space manipulator self crawling and load operation aims to solve the problems that the capturing and locking functions of the end effectors of an European manipulator and an assembling manipulator in the prior art are integrated on a capturing mechanism to cause small capturing allowance, and the end effector of the space station remote teleoperation manipulator is insufficient in mechanical power output because features of the capturing mechanism can not be achieved. The end effector comprises a supporting and protecting device, a meshed docking device, a capturing locking power driving device, a capturing locking device and a power output driving device. The capturing locking power input driving device comprises an input driving mechanism, a sixth straight gear and a lead screw. The capturing locking device comprises a disc and three sets of capturing locking fingers. The power output driving device comprises an output driving mechanism, a seventh straight gear, an output driving shaft, a pre-tightening spring and a power driving piece. The end effector capable of achieving space manipulator self crawling and load operation is used for grabbing loads of the space manipulator.

Description

technical field [0001] The invention relates to an end effector for a mechanical arm, in particular to an end effector capable of realizing self-crawling and load operation of a space manipulator, and belongs to the technical field of robots. Background technique [0002] The space manipulator is installed on the space platform, which can be used for the construction of the space station, on-orbit maintenance, and daily management, as well as for the capture, handling, replacement, and maintenance of loads, and for on-orbit satellite services. Implement on-orbit assembly and construction of large-scale space equipment, such as the assembly of large-scale reflection antennas for space observation equipment. The existing space station manipulator is generally installed on a fixed base, and its operable space is limited. In the case of maintaining the structure of the manipulator, expanding the operable space of the manipulator has become an important direction for the develop...
