Embodiment

[0067] combine figure 1 , a laser welding tool for thin-walled components, which includes a profiling plate 1, a compression strip assembly 2 and a limit block 3;

[0068] The profiling plate 1 is used as the main support body when the workpiece is assembled and welded, and its shape is consistent with the shape of the thin-walled member to be welded. The shape of the thin-walled member is arc-shaped, and the inner wing plate is spiral and has a grid structure;

[0069] The plurality of compression strip assemblies 2 are arranged on the profile plate 1 to prevent the workpiece from loosening or slipping after assembly, and to control the assembly steps of the parts well;

[0070] The limiting block 3 is arranged on the profiling plate 1, and is used to limit the workpiece during welding and prevent the workpiece from being deformed during welding.

[0071] The limit block 3 limits the inside and outside of the frame of the thin-walled member, and plays the role of assembling ...

Abstract

The invention discloses a laser welding tool and welding forming method for thin-wall components. The problems that in the prior art, the thin-wall component manufacturing cost is high, the technology is complex, and deformation after welding is large are solved. The laser welding tool for thin-wall components comprises a profiling plate, a tensioning or pressing strip assembly and a limiting block, the profiling plate serves as a main supporting frame body and is consistent with a thin-wall component in appearance, a limiting protruding block with a groove is arranged on the profiling plate, the pressing strip assembly comprises a pressing plate, an inner supporting plate, a jacking screw and a tensioning or pressing strip fixing screw, and the limiting block has the effects of assembling, positioning and preventing welding deformation of thin-wall components. The thin-wall component forming method using the tool comprises the steps of acid pickling treatment, thin-wall component mounting, teaching programming, laser positioned welding, pressing strip assembly dismounting and laser continuous welding. Thin-wall components prepared through the method are small in overall deformation, high in structural strength and good in process quality, and the manufacturing requirements of outer arc-shaped, spiral and thin-wall structural components can be met.

Description

technical field [0001] The invention relates to a metal material welding tool and a welding method, in particular to a laser welding tool and a welding forming method of a thin-walled component. Background technique [0002] Laser welding has the characteristics of high energy density, small welding deformation, high efficiency, large weld depth-to-width ratio, and high degree of automation. Compared with electron beam welding, laser welding does not require a vacuum chamber, is not subject to electromagnetic interference, and has good process accessibility. Combining robots and laser vision sensing systems can realize three-dimensional space welding and flexible welding. Laser welding can achieve height tracking, and can weld with a constant focus position relative to the surface. The consistency of penetration and welding quality are easy to control, and it is more suitable for welding of space-shaped welds. [0003] The honeycomb thin-walled component is a space multi-li...
