Multifunctional end effector for aerospace maintenance

Abstract

The invention relates to a multifunctional end effector for aerospace maintenance, and solves technical problems that an effector capable of being mounted at a tail end of a soft mechanical arm is lacked at present, and maintenance can be performed aiming at a problem that a satellite solar panel cannot be unfolded or other faults cannot be performed. The multifunctional end effector comprises a cylindrical shell, a gripper mechanism, a lifting mechanism, a transmission wheel train, a reduction gear box, a lifting motor, a gripper motor and a bottom plate, and the gripper mechanism comprises a gripper base, a friction gear, a left memory alloy spring, a right memory alloy spring, a left gripper, a right gripper, a left rolling wheel and a right rolling wheel, wherein the lifting mechanism comprises an inner-layer sleeve, a middle-layer sleeve, an outer-layer sleeve, a driving shaft and a connecting shaft. According to the multifunctional end effector, a special connector for aerospace equipment can be effectively mounted and dismounted, and the special connector can be electrified and heated.

Description

technical field [0001] The invention relates to the technical field of satellite maintenance, in particular to a multifunctional end effector for aerospace maintenance. Background technique [0002] The power source of mainstream satellites in orbit is mainly solar panels. For satellites using solar panels, the problem they often face is that the solar panels cannot be deployed, so that the satellite cannot use solar energy, and eventually the energy is exhausted and stops working. Once such a situation occurs, it is necessary to launch a tool satellite to dock with the problem satellite, and then use the robotic arm on the tool satellite to open the solar panels or use the robotic arm on the tool satellite to repair the gas failure of the satellite in orbit. There are two types of robotic arms: rigid robotic arms and soft mechanical arms. For the rigid mechanical arm (for example, the application for a patent of invention with the application publication number CN110395414...
