Description

Technical Field

[0001] The invention relates to the technical field of welding processing platforms, in particular to a laser welding rotating platform. Background Art

[0002] Welded bellows is a new type of component that has emerged in recent years at home and abroad. It can generally be used as a sensitive component, sealing component, isolation medium, pipeline connection and temperature compensator, etc. In addition to the advantages of pressure resistance, temperature resistance, corrosion resistance and good sealing, it has two outstanding advantages over traditional formed bellows: large deformation and long service life.

[0003] During the bellows welding process, precision welding equipment is used to make the metal bellows into a product that meets high requirements. The welding composition method is to weld the inner diameter rings of the butt-jointed bellows in a concentric circle manner in sequence. For example, in the prior art, the "self-adjusting laser welding equipment" with the publication number CN base positioning block 1173 mounting seat 8 positioning block 1166A includes a control cabinet, and a storage mechanism, a grabbing and walking mechanism, a welding jig positioning mechanism, a rotating workpiece mechanism and a welding gun adjustment mechanism arranged on the control cabinet. The storage mechanism is used to temporarily store the bellows to be welded, and cooperates with the grabbing and walking mechanism to transfer a single bellows to the rotating magnetic table included in the rotating workpiece mechanism in sequence; the two bellows are positioned and restricted by the inner hole through the welding jig positioning mechanism; and the collected bellows weld position information is fed back to the control system through the industrial camera. The control system is based on the received bellows weld position information and guides the welding gun adjustment mechanism to automatically track and adjust the weld. It is convenient to automatically grab and load the corrugated pipe fittings to be welded, and automatically track the welding positions of the inner diameter circles of the two corrugated pipe fittings through the welding gun adjustment mechanism. It is convenient to adjust the welding angle of the laser welding gun, realize circumferential welding, and have high welding efficiency.

[0004] However, during the implementation of the above technical solution, it was found that there were at least the following technical problems:

[0005] In the process of welding bellows, precision welding equipment is used to make metal bellows into products that meet high requirements. The welding composition method is to weld the inner diameter circles of the butt-jointed bellows in a concentric circle manner in sequence. The structure of the welding machine is relatively complex. In order to achieve circular welding movement, the bellows parts need to be welded in a circular motion. For this reason, we propose a laser welding rotating platform. Summary of the invention
