Abstract

The invention discloses a welding fixture and an application method thereof. The fixture is provided with four machining positions on a flat plate, so that the fixture can clamp four parts, and electron beam welding of four short-shaft parts can be completed at a time; the defect that electron beam welding equipment can only weld one part on one fixture every time is effectively overcome; multiple times of evacuation caused by repeated clamping of the parts are saved, and the cost and the equipment occupation time caused by multiple times of evacuation are saved while the working efficiency is improved; according to the device, four detachable positioning devices are installed on the flat plate, and due to the detachable design mode, a tool can be conveniently repaired, and positioning of the parts can be guaranteed; and the parts are positioned through inner holes and pressed through cover plates, so that positioning of the parts is guaranteed, and installation of the parts is facilitated.

Description

technical field [0001] The invention belongs to the technical field of electron beam welding, and in particular relates to a welding fixture and a using method thereof. Background technique [0002] As a special welding method, electron beam welding has the advantages of good welding accessibility, high joint strength, small welding deformation, large welding thickness, and wide range of weldable materials. It is increasingly used in precision parts in the manufacturing process. Aeroengines have many short shaft parts welded by electron beam, as follows figure 1 As shown, the part is composed of a circumferential weld seam on the end face, the axial height is about 160mm, and the diameter of the weld seam is about 130mm. Only one piece of welding can be completed each time the part is clamped, and the workload is very large and the production efficiency is low. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned shor...
