Transferring method for composite wallboards in aircraft wing box assembling process

Abstract

The invention discloses a method for transferring composite wallboards in the aircraft wing box assembling process. The method comprises the following steps that wallboards are transferred by using an upper / lower wallboard shape-preserving frame, a horizontal assembling system wallboard positioning and lifting mechanism, a wallboard turnover mechanism, an AGV (Automatic Guided Vehicle), an upper wallboard shape-preserving frame hanger and a vertical storage and cleaning device; the upper / lower wallboard shape-preserving frame is mounted on a wallboard positioning and lifting mechanism of the horizontal assembly system, and the wallboards are accurately positioned to a target position through the wallboard positioning and lifting mechanism of the horizontal assembly system; the wallboard turnover mechanism comprises turnover stand columns on the two sides and an enclosure frame in the middle, inner clamping boards of an upper wall board and a lower wall board are installed on an upper frame face and a lower frame face of the enclosure frame respectively, turnover mechanisms and lifting mechanisms are arranged on the turnover stand columns, the turnover mechanisms drive the enclosure frame to turn over by 180 degrees, the lifting mechanisms drive the enclosure frame to move up and down, and conversion between the vertical state and the horizontal state of the wall plates is achieved.

Problems solved by technology

[0002] During the assembly and manufacturing process of aircraft wings, the assembly process of the panel is the most complicated, including storage, turnover transportation / lifting, positioning on the frame, cleaning and deburring outside the frame, etc. When the final assembly station of the wing box adopts horizontal assembly At the same time, the posture of the wall panel is different at different positions. The wall panel is vertical when it is stored, cleaned and deburred outside the shelf, and it is horizontal when it is assembled. During the transfer process, the wall panels are kept in shape. In the past, the metal wall panels were usually designed to be flipped and hoisted to realize the turnover of the wall panels during the wing box assembly process, but this method required the installation of lifting joints on the wall panels. Stress concentration will occur at the connection position between the surface of the wall panel and the joint, which will affect the product, and the deformation of the panel product will not be controllable during the lifting process. Cause plastic deformation, internal damage, hidden damage, cracks and other damage, and because the center of gravity of each wall panel is different, different wall panels need to be designed with different hangers, the versatility is not strong, and the installation and removal of the process joints is time-consuming and laborious. Unnecessary troubles are caused in the subsequent wing box assembly process. Considering product safety, convenient use, and resource utilization, this lifting method is no longer suitable for the transfer of composite wall panels in the aircraft wing box assembly process. Therefore, , it is necessary to develop a transfer method for composite panels in the assembly process of aircraft wing boxes
