technical field

The invention relates to the field of aircraft assembly technology and equipment, in particular to an overall layout method of an automatic drilling and riveting machine with adjustable height and rotation angle of an aircraft wall plate.

Background technique

In aircraft assembly, riveting is still the main connection method at present. The production efficiency of traditional manual riveting is low, and the quality of riveting depends heavily on the experience and technology of the operator, which cannot further improve the assembly efficiency of the aircraft. Therefore, it is very necessary to improve the mechanization and automation of riveting for the aircraft manufacturing industry.

At present, the manufacturers of automatic drilling and riveting systems in the world mainly include EI, GEMCOR, BROETJE, etc. The automatic drilling and riveting systems developed by these manufacturers are mainly divided into two types in terms of layout, bow-arm automatic drilling and riveting systems and vertical automatic drilling and riveting systems. Riveting system, these two types of automatic drilling and riveting systems have greatly improved production efficiency, but at the same time there are many defects. For example, the bow-arm automatic drilling and riveting system needs to lift the aircraft panel and place it on the leveling bracket. Continuously adjust the attitude of the aircraft panel, and at the same time, there will be restrictions on the throat depth of the bow arm, so the work preparation time of this type of automatic drilling and riveting system is long, the aircraft panel has poor passability, and the size of the aircraft panel is limited; vertical When the automatic drilling and riveting system is working, the aircraft panel is fixed, which overcomes the shortcomings of the bow-arm automatic drilling and riveting system, which has poor passability and applicability. However, the aircraft panel still needs to be hoisted to the tooling for fixing, so the preparation time is still relatively long. Long, and the structure of this type of automatic drilling and riveting system is too complicated, which is not conducive to maintenance.

The invention can realize the hole-making and riveting between the aircraft wall plate and the internal frame. The hole-making accuracy meets the technical requirements for hole position accuracy, verticality, and smoothness, and the riveting quality meets the technical requirements for riveting strength, interference, and sealing. Requirements; ensure the accessibility and passability of aircraft panels. However, aircraft siding is immobilized, affecting the machinable area of the siding.
