【 摘 要 】

Aiming at the problems of low efficiency, poor positioning accuracy and unreconstructible of the aircraft assembly process at present, according to the structure of the fuselage section of the aircraft, a flexible tooling for the fuselage frame is developed based on the modular idea. Positioning of different models of the fuselage is achieved by servo motor, manual adjustment and positioner. According to the way of the fuselage section, the structure of the flexible tooling is determined. At the same time, the layout of the automatic drilling and riveting system of the flexible tooling and the composite processing machine tool and the assembly process of the flexible tooling are introduced. Finally, the positioning accuracy of the flexible tooling test platform was analyzed, and the experimental verification was carried out through the experimental platform.
