[0025] It is easy to understand that according to the technical solution of the present invention, without changing the essential spirit of the present invention, a person skilled in the art can propose a variety of interchangeable structural methods and implementation methods. Therefore, the following specific embodiments and drawings are only illustrative of the technical solution of the present invention and should not be regarded as the entire present invention or as a limitation or restriction of the technical solution of the present invention.

[0026] Example:

[0027] like Figure 1-3 As shown, a multifunctional blower 3 and a welding base 6 are fixedly mounted on the welding base 1. A first robotic arm 7 is fixedly mounted on the welding base 6. A second robotic arm 8 is rotatably mounted on the head of the first robotic arm 7. The first robotic arm 7 is equipped with a first motor that drives the rotation of the second robotic arm 8. A third robotic arm 9 is rotatably mounted on the head of the second robotic arm 8. The second robotic arm 8 is equipped with a second motor that drives the rotation of the third robotic arm 9. A fourth robotic arm 10 is rotatably mounted on the head of the third robotic arm 9. The third robotic arm 9 is equipped with a third motor that drives the rotation of the fourth robotic arm 10. A welding gun 12 is fixedly mounted on the head of the fourth robotic arm 10. A fireproof shielding tube 1101 is fixedly connected to the outer wall of the fourth robotic arm 10, and the welding gun 12 is placed inside the fireproof shielding tube 1101.

[0028] The top and bottom of the fire shield tube 1101 are respectively provided with a first fixing hole 1104 and a second fixing hole 1106. A spring 1105 is fixedly connected to each of these two fixing holes. Six springs 1105 are provided, and are positioned around the perimeter of the welding torch 12. A through hole 1107 is provided in the center of the bottom of the fire shield tube 1101, through which the welding torch 12 passes for welding.

[0029] The top of the fireproof shielding tube 1101 is provided with a positioning hole 1103 for installing a suction pipe 4 or a blow pipe 5. The inner diameter of the positioning hole 1103 is slightly larger than the outer diameter of the suction pipe 4 and the blow pipe 5, so that the suction pipe 4 or the blow pipe 5 is fixedly inserted into the positioning hole 1103.

[0030] The air intake port of the multifunctional blower 3 is provided with a suction pipe 4 , and the air exhaust port of the multifunctional blower 3 is provided with a blowpipe 5 .

[0031] The suction pipe 4 is provided with a diverter shell 2 .

[0032] The outer wall of the fireproof shielding tube 1101 is provided with a window 1102.

[0033] In a specific implementation, when welding is required, the welding gun 12 is directed toward the welding area, and then the welding gun 12 is used to weld the object. At this time, the bottom of the fireproof shielding tube 1101 is pressed against the welding area. At this time, the sparks generated by the welding gun 12 enter the fireproof shielding tube 1101 through the through hole 1107 at the bottom of the fireproof shielding tube 1101, thereby preventing the threat caused by the sparks. The spring 1105 can ensure that the fireproof shielding tube 1101 maintains a good and stable accommodation space.

[0034] Before welding, the suction pipe 4 is inserted into the positioning hole 1103 and the multifunctional blower 3 is activated to allow the suction pipe 4 to absorb welding fumes and dust. After welding is completed, the suction pipe 4 is removed from the positioning hole 1103 and the blowpipe 5 is inserted into the positioning hole 1103. The multifunctional blower 3 is then activated to allow the blowpipe 5 to blow air to cool the weld.
