The invention provides a method for precisely assembling a space remote sensing camera body structure, belonging to the technical field of assembly connection of body equipment. The method is to use aglue film as the close loop size of body assembly, lead assembly precision and assembly stress to depend on the deflection of the glue film, cancel the pad which may generate larger error, change theassembly mode of a transition component from glue connection first and screwed connection second of mechanical connection method into screwed connection first and glue connection second, use the metal pad to be wound on the transition component to be closely matched with an inner hole of a strut, and better achieve the aims of small assembly stress, high assembly precision and steady and firm structure through a microstress glue connection method. The glue connection method reduces the stress of the body structure on sensitive orientation, namely on axial of the strut, and optimizes the stress status of the body. Meanwhile, the method has simple and convenient operation, short assembly period and low cost, and overcomes the defects of long period and high cost of the prior assembly methodby finishing the pad.
