Detailed Description
The utility model is described in detail below with reference to the figures and the specific embodiments.
As shown in fig. 1 to 2, a scale connection pipe for a laser welding head includes a medium diameter pipe 1 and a large diameter pipe 2, a lower portion of the medium diameter pipe 1 is fixedly connected with an upper portion of the large diameter pipe 2, a small-diameter pipe 3 is arranged in the large-diameter pipe 2, the upper part of the small-diameter pipe 3 is communicated with the lower part of the medium-diameter pipe 1, a blocking groove 4 is formed between the outer wall of the medium-diameter pipe 1 and the inner wall of the large-diameter pipe 2, a plurality of through holes 5 are arranged on the medium-diameter pipe 1, the inner diameter of the small-diameter pipe 3 is smaller than that of the medium-diameter pipe 1, the inner diameter of the medium-diameter pipe 1 is smaller than that of the large-diameter pipe 2, the large-diameter pipe 2 comprises a thick-wall pipe 201 and a thin-wall pipe 202, the thick-wall pipe 201 is arranged above the thin-wall pipe 202, the thick-wall pipe 201 is communicated with the thin-wall pipe 202, the inner diameter of the thick-wall pipe 201 is smaller than that of the thin-wall pipe 202, the thick-walled pipe 201 is connected to the medium-diameter pipe 1, and the small-diameter pipe 3 is disposed in the thick-walled pipe 201.
The medium-diameter pipe 1 and the large-diameter pipe 2 are coaxially arranged.
The small-diameter pipe 3 and the large-diameter pipe 2 are coaxially arranged.
The number of the through holes 5 is four, and the four through holes 5 are sequentially arranged at intervals along the circumferential direction of the medium-diameter pipe 1.
When the utility model works, the copper nozzle is arranged below the large-diameter pipe, and the protective lens is arranged above the medium-diameter pipe. During welding, after spatter enters the large-diameter pipe from the copper nozzle, more than 72% of spatter can be blocked in the blocking groove. Because the small-diameter pipe is the narrowest passage through which the airflow of the whole scale tube passes, the pressure intensity of the air pressure of the passage wall is the smallest, under the action of the Venturi effect, partial airflow in the blocking groove can enter the medium-diameter pipe through the through hole and then enter the thin-wall pipe through the medium-diameter pipe, and after the air pressure of the blocking groove is reduced, the airflow of the thin-wall pipe can enter the blocking groove to form a small airflow ring in the area, so that welding spatters are further guided into the blocking groove, and the damage to the protective lens is further reduced. And part of splashes enter the medium-diameter pipe through the small-diameter pipe, and the medium-diameter pipe is larger in inner diameter and wider in passage, so that the part of the splashes are rebounded, and the splashes are further reduced from falling onto the protective lens.
The above embodiments are based on the technical solution of the present invention, and detailed implementation and specific operation processes are given, but the scope of the present invention is not limited to the above embodiments.
