Abstract

The invention discloses a laser welding suction nozzle and a laser welding gun. The laser welding suction nozzle comprises an installation section, a suspension section and an extension section, wherein one end, at the installation section, of the suspension section integrally joins the installation section and extends downward from the installation section; the extension section is mounted to thebottom of the suspension section; the outer periphery of the extension section at least partially protrudes out of the outer side of the suspension section to form an outer convex part; a light-transmitting hole penetrating through the upper surface and the lower surface of the outer convex part is formed in the outer convex part; and the light-transmitting hole is open at the outer side of the outer convex part to separate the outer convex part into a suction block and a pressing block. According to the laser welding suction nozzle and the laser welding gun, the light-transmitting hole is arranged on the suction nozzle without additionally reserving a laser avoiding station on the side of the suction nozzle, so that a transverse installation space of the suction nozzle is kept small enough, a laser beam is injected over a workpiece via the light-transmitting hole, the energy dissipation of the laser beam caused by deliberately prolonging a laser light path is reduced, and the weldingefficiency and the welding quality are improved.

Description

technical field [0001] The invention relates to the field of laser welding, in particular to a laser welding suction nozzle and a laser welding torch. Background technique [0002] In the field of laser welding, it is well known to adopt welding suction nozzles of different structural forms to realize suction and positioning of workpieces after suction. In the process of researching and realizing the stable suction and positioning of the workpiece to be welded, the inventor found that the laser welding nozzle in the prior art has at least the following problems: [0003] In order to ensure stable suction and stable positioning of the workpiece during the welding process, the existing laser welding suction nozzle involves many auxiliary parts, resulting in a large overall volume of the suction nozzle. The optical path causes greater interference, especially when welding delicate parts, this problem is particularly prominent. [0004] In view of this, it is necessary to deve...
