Abstract

The invention provides a bonding and assembling method of a precise carbon fiber truss, relates to the technical field of space optical remote sensing, and solves the problem that the bonding and assembling process of the precise carbon fiber truss is complicated and lengthy. The method comprises the following processes of a process for grinding the lower surface of an upper metal insert and the upper surface of a lower metal insert, and modifying a rod joint; a process of manufacturing a bonding auxiliary device; a process of manufacturing a truss rod assembly by the bonding auxiliary device;a process of assembling an upper plate assembly, the truss rod assembly and a lower plate assembly to obtain the precise carbon fiber truss. Through bonding and assembling, the secondary processing by a machine tool is not needed; the pollution and corrosion cannot be caused on the carbon fiber structure. The rod joint and the truss rod are bonded by the bonding auxiliary device; the bonding is accurate; after the bonding, the secondary processing by the machine tool is not needed; the developing period is shortened; the assembling precision is improved; the assembling difficulty is reduced;meanwhile, the precision requirements of various connectors of a space camera can be easily met; the development of a space optical remote sensing technology is propelled.

Description

technical field [0001] The invention relates to the technical field of space optical remote sensing, in particular to a method for bonding and assembling a precision carbon fiber truss. Background technique [0002] With the continuous improvement of the requirements of modern military, scientific research and other fields, space cameras are moving towards the direction of large aperture, long focal length, and high light weight. During the entire process from assembly to on-orbit work, the space camera will experience severe thermal and mechanical environmental tests. In order to ensure the imaging quality, the supporting structure of the space camera needs to have good strength, rigidity and high thermal and mechanical stability. [0003] Carbon fiber composite material is an excellent new structural material, which is widely used in lightweight structures in aviation, aerospace and other fields. design, so it is very suitable for manufacturing support structures for spa...
