Description

Technical Field

[0001] The invention relates to the technical field of laser welding equipment, in particular to a multi-surface laser spot welding machine based on laser positioning. Background Art

[0002] Laser welding is a thermal processing technology that uses a laser beam as a heat source. The laser beam is focused to form a very small but high-energy-density light spot. In the specific welding process, the laser beam generated by the laser welder is projected onto the welding point to complete the non-contact welding operation.

Once step surfaces of varying heights and multiple groups of inclined surfaces with different angles appear on the outer surface of the workpiece, the existing equipment cannot stably fix the workpiece due to the lack of an adaptive structure of the laser spot welding machine, which is not conducive to completing the welding operation of the workpiece in a stable state, and the applicability of the existing equipment is limited.
