Abstract

The invention discloses a wing root butt joint manufacturing method and a wing root butt joint manufacturing device, a butt joint and equipment. The wing root butt joint manufacturing method comprisesthe following steps of pre-mounting a butt joint rough blank and acquiring large density point cloud data of a molded surface by laser scanning; generating a fit surface of an actually assembled buttjoint according to the point cloud data and calculating the parameter dimension of the fit surface; and carrying out finish machining on the butt joint rough blank to obtain the butt joint accordingto the parameter dimension. Based on a reverse measuring design manufacturing method, the method adopts reverse measurement in actual assembly, and designs modification and manufactures and carries out clean-up machining on beam and the butt joint according to an actual fit surface, so that the potential cushioning risk is reduced greatly, the assembling difficulty and workload are reduced and theload transfer efficiency of the actual structure is improved while it is ensured that the structural strength is met.

Description

Technical field [0001] The invention relates to the technical field of aircraft design and manufacturing, and in particular to a method, device, butt joint, storage medium and equipment for manufacturing a wing root butt joint. Background technique [0002] Modern civil aircraft mainly adopt the mode of docking the integral outer wing and the middle fuselage to assemble the wing body. During the docking process, priority is given to ensuring the positioning accuracy of the upper and lower wall panels and the front and rear beam web surfaces. The four corner areas of the docking (beam butt joint position ) Is the area with the largest accumulation of tolerances, and the matching accuracy of parts is poor. During the assembly process, the central wing and outer wing sides are mainly used to add spacers to compensate for the gap to complete the assembly. [0003] The existing solutions have the following three problems in the actual application process: [0004] 1) After assembly, the ...
