Abstract Aiming at the development trend of product transfer automation and assembly digitization of the existing spacecraft digitization assembly line. A set of full-process transshipment equipment compatible with the production line and a multi-geometry bracket are designed. Based on the analysis of product transfer process, guarantee requirements and assembly requirements, a general design scheme of passive drive bracket based on power source of roller is proposed. The key force parts and weak points of the bracket are analyzed. Meanwhile, the design, calculation and verification of key components were carried out. In addition, the numerical simulation analysis and verification were carried out using special software. After the trial production of the bracket was completed, the engineering trial was carried out. The results showed that the deviations of the numerical simulation of strength and calculation values of theoretical design of the key components are within 10%, and the displacement deformation is kept below 0.1mm, which verifies the accuracy and rationality of the design. The function and performance of the bracket meet the requirements of on-site use during the engineering application stage.
