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.

Embodiment Construction

[0036] One arrow five-star satellite bracket assembly shell assembly materials are all 7050 sheets, T7451 state, total height 1875mm, it is assembled by the I and III quadrant adapter shell buckle riveting assembly, equipped with 4 strengthened reinforcing plates, 6 Two reinforced frames, 2 horizontal reinforced frames, 2 skins, 4 beams, 4 bent plates, total length 974mm, total width 650mm, skin wall thickness 2mm, rib wall thickness 4mm; satellite adapter Ⅰ, Ⅲ The four satellite docking surfaces on the quadrant bracket require flatness not greater than 0.2mm and roughness not greater than 3.2μm; the end face step difference of the bracket assembly is not greater than 0.2mm. According to the traditional process: the machine is added first and then assembled, and after the multi-part coordinated riveting assembly, due to riveting deformation and assembly errors, it cannot meet the high-precision coordination requirements of the satellite mounting surface.

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 invention relates to a thin-walled structured one-shot five-star satellite bracket manufacturing method and assembly method, in particular to a one-shot five-star satellite bracket manufacturing process for multi-part riveting complex thin-walled structure, and a multi-part riveting process Complex structure coordinated assembly technology and riveting assembly machining technology belong to the field of rocket assembly manufacturing. Background technique [0002] In order to meet the low-cost market-oriented positioning requirements of commercial civil space rockets, the characteristics of commercial rocket satellite supports are: multiple satellites with one arrow, light weight, high precision, and high strength. These characteristics require the design of the satellite bracket to be a high-strength metal thin-walled complex structure. In order to ensure its high strength and light weight, it requires very high machining accuracy, which brings many di...
