Aircraft panel butt joint structure

Abstract

The invention discloses an aircraft panel butt joint structure and belongs to the technical field of aircraft assembly. By the adoption of the provided aircraft panel butt joint structure, the aircraft surface skin layer butt joint quality can be improved, the butt joint panel dislocation can be reduced, and the butt joint assembling efficiency can be improved. Multiple butt joint units are arranged, first butt joints and second butt joints in the butt joint units are connected with butt joint edges of a first aircraft panel and a second aircraft panel which need to be connected in a butt joint manner, so that skin layers can be effectively located and can effectively maintain the shapes through the corresponding butt joints, it can be ensured that the skin layers are not deformed in the following butt joint assembling process, and therefore the quality of the surface of an aircraft is improved after the panels are assembled in a butt joint manner. In addition, in the butt joint process of the aircraft panels, the aircraft panels can be indirectly aligned through the butt joint units directly, in other words, the aircraft panels and the corresponding skin layers can be accurately located and connected in a butt joint manner only through matching and butt jointing of the corresponding butt joint units, and the butt joint dislocation of the aircraft panels can be avoided. The assembling efficiency can be improved as well.

Description

technical field [0001] The invention relates to the technical field of aircraft assembly, in particular to an aircraft wall plate butt joint structure. Background technique [0002] Aircraft siding is usually a thin-walled structure composed of a skin layer and a skeleton layer of an internal reinforcement structure. At present, during the butt joint process of thin-walled aircraft panels, the reinforcements at the joint are generally only installed on one of the panels, resulting in no reinforcement inside the other panel, and the skin layer is not fixed during the docking process. Effective fixed constraints lead to easy deformation of the skin at the joint, which affects the appearance of the joint. In addition, the existing butt jointing method of wall panels usually achieves indirect positioning through positioning holes provided on the reinforcement, and guides through guide plates to complete the butt jointing. However, in such an assembly method, the butt joint edg...

Problems solved by technology

However, in such an assembly method, the butt joint edges of the skin layers lack protection, which easily deforms the wall panel structure without internal reinforcement and its skin layers, and the skin edges are usually far away from the positioning holes, so it is easy to cause butt joint misalignment; and Due to the weak skin edge structure, it is easy to hinder the docking work, resulting in low docking efficiency

In summary, the existing butt joint structure of aircraft panels has disadvantages such as poor aircraft surface quality, easy dislocation of panels, and low assembly efficiency.
