When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
As shown in fig. 1, an embodiment of the present application provides a handheld laser welding torch nozzle auxiliary positioning device, which includes: nozzle mount 110, connecting arm 120, plunger mounting block 130, and ball plunger 140.
The two ends of the connecting arm 120 are respectively connected with the nozzle fixing seat 110 and the plunger mounting block 130, the nozzle fixing seat 110 is used for fixing the handheld laser welding gun nozzle 200, the plunger mounting block is provided with a plurality of ball plungers 140, each ball plunger 140 comprises a ball head portion, and the ball head portion of each ball plunger 140 and the nozzle fixing seat 110 are located on the same side of the connecting arm 120.
The auxiliary positioning device 100 can be used with reference to fig. 2. The torch nozzle 200 is fixed to the nozzle holder 110. Here, the nozzle holder 110 may be adapted according to different nozzle forms, so that the welding torch nozzle 200 can be stably fixed to the nozzle holder 110. The connecting arm 120 connects the lower plunger mounting block 130 with the nozzle holder 110. Three ball plungers 140 can be mounted on the plunger mounting block 130, before welding is ready, the angle between the welding nozzle and the auxiliary positioning device 100 is adjusted to a position convenient for operation, the guide red light of the handheld laser welding machine is turned on, the extending length of the three ball plungers 140 on the plunger mounting block 130 is adjusted, and the guide red light is accurately positioned at the position of a gap to be welded.
