Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skilled in the art without making creative labor belong to the protection scope of the utility model. It should be noted that the embodiments in the application and the features in the embodiments can be combined with each other in any way without conflict.
[0022] Please refer to Figures 1 to 3 The copper nozzle 40 mounting structure with multi-path dust extraction comprises a mounting plate 10, an upper layer pipeline 20 arranged on the mounting plate 10, a lower layer pipeline 30 arranged below the mounting plate 10, and a copper nozzle 40 mounted on the mounting plate 10. One end of the upper layer pipeline 20 is located above the copper nozzle 40, and the other end is connected to a dust removal machine. One end of the lower layer pipeline 30 is located below the copper nozzle 40, and the other end is communicated with the upper layer pipeline 20. The upper layer pipeline 20 and the lower layer pipeline 30 can respectively extract dust above and below the copper nozzle 40, thereby improving the dust extraction effect.
[0023] Please refer to 2 and Figure 3 A mounting hole 11 is formed through the mounting plate 10, and the copper nozzle 40 is arranged in the mounting hole 11. A hole in the copper nozzle 40 is coaxially arranged with the mounting hole 11, and laser is used for laser processing through the mounting hole 11 and the copper nozzle 40. One end of the upper layer pipeline 20 is communicated with the inner wall of the mounting hole 11, and the other end is connected to the dust removal machine. The connection between the upper layer pipeline 20 and the mounting hole 11 is located above the copper nozzle 40. When the dust removal machine is turned on, dust can be removed from above the copper nozzle 40 through the upper layer pipeline 20.
[0024] Preferably, the upper layer pipeline 20 is located in the mounting plate 10, so as to simplify the overall mounting structure and avoid the complexity of the structure caused by the external pipeline of the mounting plate 10. In the embodiment, a gas guide groove 21 is formed on the top surface of the mounting plate 10. A cover plate 22 is arranged on the gas guide groove 21. The cover plate 22 is fixedly connected to the mounting plate 10 by bolts. A sealing gasket 23 is arranged between the cover plate 22 and the mounting plate 10. The gas guide groove 21, the cover plate 22 and the sealing gasket 23 cooperate to form the upper layer pipeline 20. In the embodiment, the gas guide groove 21 can be directly formed by grooving on the existing mounting plate 10 structure, without the need to additionally manufacture the mounting plate 10, thereby saving cost. Figure 2 The top view of the embodiment without the cover plate 22 is shown. Preferably, the mounting plate 10 is an insulating plate.
[0025] The lower pipeline 30 is arranged below the mounting plate 10, one end of the lower pipeline 30 is aligned with the lower end of the copper nozzle 40, and the other end of the lower pipeline 30 is communicated with the upper pipeline 20. When the dust removal machine is turned on, dust removal can be performed from below the copper nozzle 40 through the lower pipeline 30. Specifically, a connecting hole 24 is formed in the inner wall of the side of the upper pipeline 20 facing downward, the connecting hole 24 penetrates the bottom surface of the mounting plate 10, and one end of the lower pipeline 30 is communicated with the upper pipeline 20 through the connecting hole 24. The copper nozzle 40 is arranged in the mounting hole 11, a dust removal port 41 is formed in the bottom side wall of the copper nozzle 40, and the other end of the lower pipeline 30 is connected to the dust removal port 41. As shown in Figure 3 .
[0026] Preferably, valve bodies (not shown in the figure) are arranged in the upper pipeline 20 and the lower pipeline 30, and the valves can be selectively opened. A single valve body is opened to select the upper pipeline 20 for dust removal, or the lower pipeline 30 for dust removal, or both valve bodies are opened to simultaneously use the upper pipeline 20 and the lower pipeline 30 for dust removal. When the upper pipeline 20 and the lower pipeline 30 are used for dust removal at the same time, the smoke and dust is first discharged through the lower pipeline 30, and when the smoke and dust that has not been timely discharged by the lower pipeline 30 escapes upward, it is adsorbed and discharged by the upper pipeline 20. The upper pipeline 20 and the lower pipeline 30 cooperate to remove dust, thereby optimizing the dust removal effect. As shown in Figure 3 , the arrows in the figure represent the direction of the airflow.
[0027] An air outlet 42 is formed in the bottom side wall of the copper nozzle 40, and protective gas is introduced into the copper nozzle 40 through the air outlet 42 to prevent oxidation of the welding part during laser welding. Preferably, the dust removal port 41 is located above the air outlet 42 to avoid the protective gas discharged from the air outlet 42 being sucked out during dust removal of the lower pipeline, thereby affecting the welding quality.
[0028] Preferably, a plurality of upper pipelines 20 are arranged on the mounting plate 10, each upper pipeline 20 corresponds to a lower pipeline 30, and the upper pipelines 20 are all connected to the inner wall of the mounting hole 11. The plurality of upper pipelines 20 and the lower pipelines 30 are used for dust removal at the same time, thereby improving the dust removal effect.
