Laser welding tool for thin wall complex surface cabin body and molding method

Abstract

The invention relates to a laser welding tool for a thin wall complex surface cabin body and a molding method, in particular to the laser welding tool suitable for the thin wall complex surface cabin body and the welding molding method of the laser welding tool and aims at providing the laser welding tool for the thin wall complex surface cabin body and the cabin body molding method. The tool and the method solve the problems that by means of an existing method, the machining cycle is long, the material utilization rate is low, production efficiency is low, cost is high and adaptability is poor. The laser welding tool for the thin wall complex surface cabin body comprises a bearing frame body, wrap belt assemblies and front and rear cover plates (1 and 2). The bearing frame body is used for fixing a cabin body (3). The wrap belt assemblies comprise wrap belts (4) and connecting pieces. The wrap belts are provided with locating through holes (5). The cover plates are provided with gas through holes (7). The thin wall complex surface cabin body molding method adopting the tool includes the steps of cleaning treatment, framework mounting, teaching programming, skin mounting, laser locating and welding, wrap belt assembly detaching and laser continuous welding.

Description

technical field [0001] The invention relates to a metal material welding tool and its welding forming method, in particular to a laser welding tool suitable for a thin-wall complex curved surface cabin and its welding forming method. Background technique [0002] Modern aircraft are developing towards high Mach and long flight time, requiring the aircraft structure to have good high-temperature bearing capacity and high-temperature durability, which puts forward higher requirements for the materials used in the aircraft. A cabin with thin walls and complex curved surfaces is a key component of a certain type of product, and its structure is as follows figure 1 , 2 , as shown in 3, where image 3 Schematic diagram of the structure of the welded cabin, figure 1 It is a schematic diagram of the skeleton structure before welding, figure 2 It is a schematic diagram of the skin structure before welding, and the cabin can be obtained by welding the skin to the skeleton.
