Description

Technical Field

[0001] The utility model relates to the technical field of laser welding, and more specifically to an adjustable double-head welding machine. Background Art

[0002] Laser welding is a welding technology that uses a high-energy-density laser beam as a heat source to locally heat the material to a molten or near-molten state, thereby achieving material connection. During the production of steel cups, a pendant needs to be welded to the outer surface of the steel cup. The outer surface of the steel cup is circular, and the pendant is rectangular.

[0010] The surface of the sleeve column is smooth, and the outer surface of the limiting disk is bonded with a silicone pad, which can prevent scratches from occurring on the bare back surface.

[0011] Limiting holes are provided on the front and rear side walls of the rectangular plate, and a limiting rod is movably mounted inside the limiting hole. The two ends of the limiting rod are respectively fixedly mounted on the side walls of the mounting plate and the welding seat, wherein the rectangular plate can be limited by the limiting rod to avoid position displacement of the rectangular plate during movement.
