Problems solved by technology

[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

Abstract

The invention discloses a laser welding suction nozzle and a laser welding torch. The laser welding suction nozzle comprises: an installation section; extending downward; and an extension section, which is installed to the bottom of the overhanging section; wherein, the outer periphery of the extension section at least partially protrudes from the outside of the overhanging section to form an outer protrusion, and the outer protrusion has a The light-transmitting hole runs through the upper and lower surfaces thereof, and the light-transmitting hole is opened on the outer side so as to separate the convex part into a suction block and a pressing block. According to the present invention, the light-transmitting hole is set on the suction nozzle without reserving an additional laser avoidance station on the side of the suction nozzle, so that the lateral installation space of the suction nozzle is kept small enough, and the laser beam can pass through the light-transmitting hole Injecting from directly above the workpiece reduces the energy dissipation of the laser beam due to the intentional extension of the laser optical path, and improves the welding efficiency and welding quality.

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...
