Embodiment Construction

[0021] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0022] The invention provides a welding fixture for laser circumferential seam welding of multi-layer thin-walled annular parts, such as figure 1 As shown, including positioning plate 1, the material of positioning plate 1 is copper T2, and its surface is chrome-plated; three positioning pins 3 are distributed on positioning plate 1, and there are three threaded holes for connecting mandrel 2 on positioning plate 1 , the outer diameter of the positioning disc 1 is smaller than the outer diameter of the workpiece to be welded. When the workpiece is welded, the welding adhesion between the parts and the positioning disc 1 is avoided; The surface washer 6 is covered with a gland 4, and the conical washer 6 is also provided with a spherical shoulder nut 5, the spherical shoulder nut 5 is combined with the conical washer 6 ...

Abstract

The invention discloses a welding fixture for laser circumferential seam welding of a multi-layer thin-wall ring part. The welding fixture comprises a ring-shaped positioning plate made of red copper,and the surface of the positioning plate is plated with chromium; the positioning plate is provided with a gland in a matched mode, the gland is made of red copper, and the surface of the gland is plated with chromium; a taper gasket is arranged on one side of the positioning plate and sleeved with a fastening device for pressing the gland and the positioning plate; and a positioning device is further arranged between the positioning plate and the gland. In the laser circumferential seam welding process, parts are effectively prevented from adhering to the fixture, the phenomenon of welding deformation is eliminated, and the problem of buckling deformation of the parts during welding is solved.

Description

technical field [0001] The invention belongs to the technical field of laser welding and relates to a welding fixture for laser circumferential seam welding of multi-layer thin-walled annular parts. Background technique [0002] Laser circumferential seam welding of traditional multi-layer thin-walled ring parts made of GH605 is welded with steel fixtures. After the outer ring seam welding is completed, the parts will stick to the fixture, and the welding deformation of the ring inner ring will warp, and the thickness direction will warp. 0.3mm~1.2mm. In the follow-up, the separation of fitters and thermal stabilization treatment with heat treatment fixtures are adopted to ensure the requirements of the design drawings. However, in the process of using a fitter to separate parts and fixtures, it is easy to further increase the deformation of the parts, and even cause the parts to be scrapped due to tearing, and the product qualification rate is low.
