Abstract

The invention discloses an automatic assembly system of a spacecraft cabin section on the ground, and belongs to the technical field of large-sized space measurement assembly. The automatic assembly system aims to solve the problems that when a conventional spacecraft cabin section is assembled on the ground, the stability is poor, and the abutting precision is low. The assembly system comprises a master control system, a laser tracker and a parallel mechanism, wherein the master control system is used for controlling the laser tracker, obtaining the position of a fixed-section end surface of the cabin section, the position of a movable-section end surface of the cabin section, and the position of the parallel mechanism according to position information measured by the laser tracker, obtaining the relative position data of the fixed-section end surface and the movable-section end surface through calculation according to the obtained position information, and controlling the parallel mechanism according to the relative position data; the laser tracker is used for measuring the position information of the fixed-section end surface, the position information of the movable-section end surface, and the position information of the parallel mechanism by utilizing a T-Probe or a target sphere; the parallel mechanism is used for controlling the motion of the movable section of the cabin section according to the control of the master control system. The assembly system disclosed by the invention is used for spacecraft production.

Description

technical field [0001] The invention belongs to the technical field of large-scale space measurement and assembly. Background technique [0002] Modern aircraft, rockets and missiles have a large number of components, complex shapes, and light, thin and easily deformable structures, which make their assembly a complex project with great difficulty and multiple fields of design. The assembly process largely determines the final quality, manufacturing cost and production cycle of aircraft, rockets and missiles. [0003] At present, the docking and separation of most of the spacecraft's large modules is a vertical hoisting method, and its safety and quality mainly depend on the engineering experience of the technicians and the individual skill level of the operators, and the stability and accuracy of the docking cannot be guaranteed. [0004] Large-scale space measurement and assembly technology has played an irreplaceable and important role in the automated production process...
