A positioning method for aircraft skin and panel parts of multiple models

Abstract

The invention provides a method for positioning parts such as aircraft skins and wall plates of multiple models. According to the method, on the basis of original process lugs and original positioning holes, two new process lugs are installed on the two sides of each original process lug correspondingly according to a manufacturing data set and the shapes and sizes of the aircraft skins and wall plates, and each original process lug is clamped between the two corresponding new process lugs; and then according to the appearances and hole positions of drilled sample plate holes, positioning holes are drilled in the new process lugs and the original process lugs, and finally the parts such as the aircraft skins and wall plates of multiple models or similar models are positioned on an assembling tool. According to the method, the positioning accuracy of the parts such as the skins and wall plates on the assembling tool can be guaranteed; and in addition, operation is simple, rapid and convenient, the manufacturing cost is low, the manufacturability is good, and the utilization efficiency of the assembling tool is greatly improved.

Description

technical field [0001] The invention relates to a positioning method for aircraft skin and wall board parts of multiple models, belonging to the technical field of aircraft assembly. Background technique [0002] With the continuous improvement of the level of aviation manufacturing, the requirements for the aerodynamic shape and stealth of the aircraft are also increasing. Large-scale integral skin and panel parts have become the main load-bearing components widely used in the design and manufacture of modern aircraft. The use of large overall skin and panel structures can not only improve the aerodynamic shape performance and stealth performance of the aircraft, but also the large overall structure has good air tightness, high strength-to-weight ratio, and good workmanship, and is widely used in the field of modern aircraft manufacturing. , especially the important components with high aerodynamic shape requirements such as the middle fuselage, the overall fuel tank, and t...

AI Technical Summary

Problems solved by technology

Since the process lugs on the skin and wall panels and the positioning holes on the lugs are manufactured in coordination with the manufacturing data set of this model, and the positioning holes on the lugs are drilled according to the hole-making templates of the skin and wall panels of this model , so this method is only suitable for the positioning of a single model (variety) of aircraft skins and panels, and cannot realize the positioning of skins and panels of multiple models or similar models on a set of assembly frames, especially for multiple aircraft types When working in parallel, there are high requirements on the type and quantity of assembly tooling, which cannot adapt to the beat of the production line, and the assembly cycle is longer, the manufacturing cost is higher, and it is difficult to improve the utilization rate of assembly tooling
