Abstract As a large precision test equipment for low gravity simulation of spacecraft, the large super flat support platform has the characteristics of large size, high bearing stiffness and automatic and precise adjustment. Based on large super flat support platform assembly requirement and difficulty analysis, building an assembly system, drawing assembly process flow, designing and adjusting mechanism and adjusting the process flow, and for building virtual contour, precision measurement, assembly path planning control strategy, and other key digital automatic assembly technologies are studied. Finally, precise measurement and adjustment is achieved by the large flat supporting platform, and the completion of high efficiency, high quality of precise assembly of 200 pieces of platform is realized.
