Problems solved by technology

Due to the light weight requirements of the space truss lift-off, the space truss mostly uses tubular components. The existing space truss docking mechanism can only self-lock the truss tube body, and the error caused by the long-distance space truss docking cannot be adjusted.

Abstract

A space truss quick-connect error adjustment mechanism belongs to the technical field of truss quick-plug and docking mechanisms. The space truss quick connection error adjustment mechanism includes two support frames and a branch chain 1, a branch chain two and a branch chain 3 arranged in parallel between the two support frames. The support frame includes a triangular connecting frame, and the connecting frame The three vertices of the joint are connected with two-way quick-plug joints. The two-way quick-plug joint is a symmetrical structure, which includes an end cover, a sleeve and a joint base. Both sides of the joint base are connected with sleeves, and the sleeve Connected with the end cover, the inside of the joint base is provided with a base column protrusion, the first branch includes an electric cylinder 1 and a cross universal hinge arranged in series, and the second branch includes an electric cylinder 2, a deflection hinge and a ball arranged in series. The hinge and the branch chain three include a spherical hinge, a connecting rod and a spherical hinge arranged in series. The space truss quick connection error adjustment mechanism can adjust the space truss docking error and ensure the overall linear accuracy of the truss.

Description

technical field [0001] The invention relates to the technical field of a truss quick-plug and docking mechanism, in particular to a space truss quick-connect error adjustment mechanism. Background technique [0002] Some specific functions of space operation satellites require a truss-type functional structure, and there are certain linear accuracy requirements for the space truss-type structure. There is an error in the combination of truss elements, and when multiple elements of a long-distance truss are connected in sequence, the accumulation of errors will lead to an increase in the straightness deviation of the truss, which does not meet its functional requirements. Therefore, it is necessary to perform real-time error adjustment during the docking process of truss elements to meet the requirements of long-distance truss linearity accuracy. Due to the light weight requirements of space trusses for lift-off and transportation, space trusses mostly use tubular components...
