Double-laser-welding integrated welding head

Abstract

The invention relates to the field of laser welding, in particular to a double-laser-welding integrated welding head. The double-laser-welding integrated welding head comprises a laser head interface, a nozzle base, an outer base, L-shaped screwed joints, an inner core sleeve, an outer connecting sleeve and an auxiliary laser assembly. The nozzle base is installed on the lower side of the laser head interface, the nozzle base is sleeved with the outer base, a shielding gas cavity is formed between an installing base body of the outer base and a base body of the nozzle base, a connecting shaft of the nozzle base is sleeved with the inner core sleeve, the interior of the connecting shaft and the interior of the inner core sleeve are communicated to form a welding laser channel, a shaft sleeve part of the outer base is sleeved with the outer connecting sleeve, the shaft sleeve part of the outer base and the connecting shaft of the nozzle base are communicated, and the outer connecting sleeve and the inner core sleeve are communicated, so that a shielding gas channel is formed; the L-shaped screwed joints are fixedly arranged on the two sides of the outer base, and the auxiliary laser frame assembly is arranged on the outer side of the outer base. The length of the shielding gas channel is adjustable, and the accuracy of the auxiliary teaching process of a teaching tool is effectively guaranteed.

Description

technical field [0001] The invention relates to the field of laser welding, in particular to a double laser welding integrated welding head. Background technique [0002] The main body of the robot-based double-action laser welding mechanism needs to plan the welding trajectory of the robot through teaching. Due to the complexity of the welding process and the different structural forms of the welded parts, the laser welding head in the prior art is prone to interference, and The position of the shielding gas protection is not adjustable, so it is difficult to protect the welding more effectively. In addition, the teaching process of the robot mechanical tooling is relatively cumbersome. How to effectively ensure the accuracy of the auxiliary teaching process of the teaching tooling is also a problem that needs to be solved in practice. Contents of the invention [0003] The purpose of the present invention is to provide a dual laser welding integrated welding head, the le...
