A thin-walled one-arrow five-star satellite bracket and its assembly method

Abstract

The invention relates to a one-rocket five-satellite satellite bracket with a thin-wall structure and an assembly method thereof, which adopt a scheme of firstly coordinating assembly and then mechanically guarantee, thereby avoiding the reference deviation of a satellite installation surface caused by deformation led by assembly, ensuring the precision of the satellite installation surface and the manufacturing and processing precision of the one-rocket five-satellite satellite bracket, and meeting the requirements of satellite installation and use. The one-rocket five-satellite satellite bracket with the thin-wall structure and the assembly method thereof are successfully applied to model products and proved to be correct and reliable by completing flight test verification,. According tothe one-rocket five-satellite satellite bracket with the thin-wall structure and the assembly method thereof, a rubber tire is arranged, so that the stability of the bracket in the process of removing the allowance is ensured, and trembling is avoided. A process hole is arranged when a L-shaped connecting plate is connected with the lower end surface of a second reinforcing frame in the assemblyprocess, and the L-shaped connecting plate is connected with the lower end surface of the second reinforcing frame through a process nail, so that the stability of the whole satellite bracket in the process of removing the allowance is ensured, and the damage to a rivet and a connecting hole in the process of removing the allowance is avoided.

Description

technical field [0001] The present invention relates to a thin-walled one-arrow five-star satellite support manufacturing method and assembly method, in particular to a multi-part riveted complex thin-wall structure one-arrow five-star satellite support process manufacturing scheme of the whole process, multi-part riveting Coordinated assembly technology for complex structures and machining technology for riveted assemblies belong to the field of rocket assembly and manufacturing. Background technique [0002] In order to meet the positioning needs of commercial civil aerospace rockets and low-cost marketization, the characteristics of commercial rocket satellite brackets are: one rocket with multiple satellites, light weight, high precision, and high strength. These characteristics require that the design of the satellite bracket is a complex structure of high-strength metal and thin-walled. In order to ensure its high strength and light weight, the processing accuracy is v...

AI Technical Summary

Problems solved by technology

Among them, the height of the satellite bracket is high, the docking surface is complex, the docking accuracy is high, and the weight requirements of the satellite bracket are also very strict

Using the traditional machining-riveting assembly process, the correction workload is large and the efficiency is low. Due to the limitation of manual technical level, not only the requirements for machining and riveting assembly are high, but also there are still local deformations after the assembly is formed, which cannot meet the requirements of satellite assembly.
