Cantilever type multi-axis turntable for posture adjustment of spacecraft

Abstract

The invention discloses a large-span cantilever type triaxial posture adjustment turntable for a spacecraft. The turntable comprises a supporting platform, an omnibearing travelling wheel system, a lifting system, an overturning system and a rotating mechanism, wherein the inner side of a C-type ring of an overturning rack is connected with the outer side of a rotating ring through a roller combination, the inner side of the C-type ring surrounds the outer side of the rotating ring, the rotating ring is adjusted to be in a proper assembling, testing or experimenting state, the spacecraft is locked dead by a locking device of the rotating ring, and then related working items of the spacecraft are carried out. According to the invention, opening assembly requirements of embedded products such as a high-thrust engine and the like as well as products such as narrow space pipes and the like of the spacecraft are met, reachability and convenience of operation are achieved, and the problem ofstructural deformation in the large-span and large-mass load cantilever state is solved.

Description

technical field [0001] The invention belongs to the technical field of spacecraft assembly, and in particular relates to a large-span cantilever type three-axis attitude-adjusting turntable, which can realize the openability of spacecraft embedded products and meet the assembly and testing requirements of the products. Background technique [0002] With the development trend of large-scale, compact layout and personalized appearance of spacecraft products, the demand for attitude adjustment of spacecraft assembly is becoming more and more common. Large turntables are required to adjust the attitude of spacecraft to meet the needs of spacecraft assembly, testing and testing. demand. [0003] At present, in order to meet the requirements of spacecraft assembly, testing and experimentation, the bottom connecting flange of the spacecraft is conventionally connected to the two-axis turntable, and the attitude adjustment requirements of the spacecraft are realized through the rota...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the above technical problems, the object of the present invention is to provide a large-span cantilever-type three-axis attitude-adjusting turntable for spacecraft, which solves the problem of structural deformation under the cantilever state of large-span and large-mass load, and effectively improves the assembly of products. The openness realizes the requirements of different attitudes of embedded products such as spacecraft high-thrust engines in the process of assembly and testing
