Embodiment Construction

[0032] A multi-degree-of-freedom tie rod attitude measurement and positioning method, which can realize the precise installation of the tie rod joint and the adapter flange, and ensure the dimensional accuracy and shape tolerance of the matching center hole, such as Figure 4 As shown, by establishing the installation datum plane of the satellite storage tank, the transfer flange and the tie rod joint are aligned. Cooperate with the sleeve and the drill bit to continue screwing the center hole to drill and ream the hole. Finally, ream and ream the removed tie rod joint and transfer flange. After the center hole is drilled, complete the transfer flange and tie rod joint positioning. Measure and adjust.

[0033] like figure 1 , figure 2 , Figure 5 As shown, the positioning device includes: 1 is the tie rod joint, 2 is the adapter flange, 3 is the drill sleeve, 4 is the drill bit, 5 is the positioning device, and 6 is the fixed cardan; during the matching process, each tie r...

Abstract

A multi-degree-of-freedom tie rod attitude measurement and positioning method, through the positioning device and the drill sleeve, the position accuracy of the tie rod joint and the flange matching hole is guaranteed, and the hole punching caused by the displacement and rotation of the multi-degree-of-freedom direction at the joint is avoided Deviation improves the efficiency of assembly and adjustment. By properly extending the length of the guide part of the drill sleeve, the coaxiality and matching accuracy of the upper and lower holes of the tie rod joint and the upper hole of the flange are ensured, so that the subsequent screw fasteners can be installed smoothly. , effectively solved the problem of the installation accuracy of the tie rod and the flange, ensured the reliable connection between the tie rod and the flange, provided a guarantee for the correct installation of the satellite propulsion system, and is of great significance to the subsequent reliable and normal operation of the propulsion system.

Description

technical field [0001] The invention relates to a method for attitude measurement, adjustment and positioning of a multi-degree-of-freedom pull rod, which belongs to the technical field of precise assembly of space structures. Background technique [0002] During the launch process of the satellite, it will bear the huge overload from the launch vehicle. Therefore, it is necessary to ensure that the satellite structure and the instruments carried on the satellite are safe, reliable, and have normal working accuracy. The satellite propulsion system is an important part of the satellite, which is used to guide the orbit change after the satellite and the rocket are separated, and to adjust and control the attitude of the satellite when working in space orbit. The satellite propulsion system is composed of storage tanks, engines and various pipes and valves, which are installed and welded in a certain order and direction through pipes of different diameters. The installation q...
