Problems solved by technology

Because conventional electron beam welding needs to be carried out in a vacuum chamber, because the weld has high quality requirements and is welded in a high vacuum environment, most of the short ring parts can only be welded once each time, the workload is very large and the production low efficiency

Embodiment

[0040] Such as figure 1 As shown, the welding fixture of the present invention clamps multiple short ring parts at one time clamps 3 parts, such as the first part 2, the second part 4 and the third part 6, in the clamping parts ( 2, 4 and 6), the large diameter end of the first part 2 is placed on the upper surface of the chassis 1, and then the first transition ring 3 is placed on the end face of the small diameter end of the first part 2, so that the first The boss on the lower surface of the transition ring 3 extends into the small-diameter end of the first part 2 and the inner edge surface of the small-diameter end of the first part 2 is in contact with the outer sidewall of the boss on the lower surface of the first transition ring 3. The first transition ring 3 The lower surface on the lower surface is in close contact with the end surface of the small-diameter end of the first part 2; The boss extends into the small-diameter end of the second part 4 and the inner edge ...

Abstract

The invention relates to a welding fixture for once clamping multiple short ring parts. The welding fixture comprises a chassis; a screw rod is arranged at the axis of the chassis, and is coated with multiple transition rings; bosses are respectively arranged on the upper and lower surfaces of the first transition ring; the outer side walls of the bosses and the inner edge surfaces of small-diameter ends of parts are in clearance fit; grooves are respectively formed in the upper and lower surfaces of the second transition ring; the inner side walls of the grooves and the outer edge surfaces of the large-diameter ends of the parts are in clearance fit; the first transition ring and the second transition ring are alternately arranged; the screw rod is coated with a pressing plate; a through hole in clearance fit with the screw rod is formed in the axis of the pressing plate; and the lower surface of the pressing plate is set as a coaxial lower boss or lower groove. The welding fixture effectively makes up the defect that electronic beam welding equipment only can weld one part on one fixture at each time, saves multiple vacuumizing phenomenon caused by repeated part clamping, saves the cost and the equipment occupation time caused by multiple times of vacuumizing when improving the working efficiency, improves the efficiency, and saves the cost.

Description

[0001] 【Technical field】 [0002] The invention belongs to the field of welding technology, in particular to a welding fixture for clamping multiple short ring parts at one time. [0003] 【Background technique】 [0004] 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. Because conventional electron beam welding needs to be carried out in a vacuum chamber, because the weld has high quality requirements and is welded in a high vacuum environment, most of the short ring parts can only be welded once each time, the workload is very large and the production low efficiency. [0005] 【Content of invention】 [0006] In order to solve the problems in the prior art, the object of the present invention is to provide a welding fixture for clamping multiple...
