Aircraft engine tubular support integral welding method and aircraft engine tubular support

Abstract

The invention relates to an aircraft engine tubular support integral welding method and an aircraft engine tubular support. The welding method comprises the following steps: when two or more support tubes are welded together, arranging a support connector at each of the angle connecting parts of the support tubes, and meanwhile arranging a bayonet socket at the position, facing the support tubes,of each of the support connectors; and during welding, inserting the angle connecting ends of the support tubes into the bayonet sockets in a one-to-one correspondence manner and welding together. With the adoption of the aircraft engine tubular support integral welding method and the aircraft engine tubular support, the following benefits are achieved: tubes can be applied to manufacture of aircraft engine supports, the problem that the support tubes have blind zones at the angle connecting parts in the welding process of the conventional aircraft engine support is solved, repeated detectingand welding are not needed, the welding strength of the integral aircraft engine support is greatly improved, the firmness is good, the welding operation is easy and high in efficiency, and the processing dimensions are accurate.

Description

technical field [0001] The invention belongs to the technical field of aircraft production and processing, and in particular relates to an integral welding method for an aircraft engine tubular support and the aircraft engine tubular support. Background technique [0002] In aircraft production, the strength requirements for engine brackets are very high, and no missing welding is absolutely allowed. At present, the existing aircraft engine bracket production and processing technology is to directly weld several brackets, but because the existing pipe welding process often has the problem of welding blind spots at the corner joints, that is, in the gap between two bracket tubes Welding is impossible because the welding torch cannot reach in, especially when welding large and complex engine brackets, there is inevitably fillet welding of the bracket tubes; therefore, the application of tubes with the inherent advantages of light weight and high strength is limited in aircraft...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the above-mentioned problems existing in the prior art, the present invention provides a pipe that can be applied to the manufacture of aircraft engine brackets, and at the same time solves the problem of blind spots at the corner joints between the bracket tubes in the welding process of the existing aircraft engine brackets, No need for repeated testing and welding, high welding strength, good firmness, easy welding operation, high efficiency, accurate processing size of the overall welding method of the aircraft engine tubular bracket, and the aircraft engine tubular bracket processed by this welding method
