The processing mechanism includes an air suction pump 7 fixedly installed on the top of the processing table 1, and the discharge end of the air suction pump 7 is connected to the outside of the processing workshop. The input end of the air suction pump 7 is fixedly connected to a telescopic hose 8 interconnected with the inside thereof, and the end of the telescopic hose 8 is fixedly installed with a ferrule 9 interconnected with the inside thereof, and the inner side wall of the ferrule 9 is fixedly installed with a rubber pad 10, and the rubber pad 10 is fixedly connected to the top of one of the sliding plates 3. Through the arrangement of the sliding plate 3, the cover frame 11, the driving mechanism and the processing mechanism, when surfacing welding is performed on the steel pipe, the irritating gas generated during surfacing welding can be blocked and cleaned, thereby reducing the inhalation of the operator and avoiding the discomfort caused by the operator inhaling too much irritating gas;

[0022] A cover frame 11 is fixedly installed on the top of the other sliding plate 3, and an air inlet is provided on the left side wall of the cover frame 11. A placement rack 12 is fixedly installed on the inner top of the cover frame 11, and an electric welding gun 13 is provided on the inner top of the cover frame 11. The electric welding gun 13 is placed on the placement rack 12. A blocking plate 14 is rotatably connected to the side wall of the cover frame 11, and an operating mechanism is provided on the blocking plate 14. The operating mechanism includes a protective mirror 15 fixedly installed on the blocking plate 14. Two circular openings 18 are penetrated on the blocking plate 14, and an annular airbag 19 is fixedly installed in the two circular openings 18.

[0023] A slot 20 is provided at the top of the blocking plate 14, and a fixing mechanism is provided on the side wall of the cover frame 11. The fixing mechanism extends into the slot 20 and abuts against its inner bottom.

[0024] The functional principle of the utility model can be explained through the following operation modes:

[0025] When it is necessary to perform surfacing welding on the steel pipe, first, the operator places the steel pipe between the two clamps 2, the two clamps 2 fix it, and then starts the servo motor 5, the servo motor 5 drives the double-headed screw 6 to rotate, and the double-headed screw 6 drives the two sliding plates 3 to slide, so that the side wall of the rubber pad 10 in the ferrule 9 is against the left end of the steel pipe. At this time, the right end of the steel pipe is inserted into the cover frame 11, and then the operator passes both hands through the corresponding circular openings 18 respectively, the annular airbag 19 on the circular opening 18 presses the operator's arm tightly, and then the operator removes the electric welding gun 13 on the placement rack 12 and can perform surfacing welding on the steel pipe through the protective glasses 15. During surfacing welding, the operator starts the suction pump 7, and the suction pump 7 works to generate suction to remove the suction generated during surfacing welding. The irritating gas is sucked in through the steel pipe, and then discharged outside the processing workshop through the discharge end of the suction pump 7. After the surfacing is completed, the operator places the welding gun 13 on the placement rack 12, and then controls the servo motor 5 to rotate in the opposite direction, so that the two sliding plates 3 gradually move away from each other, the rubber pad 10 on the sleeve 9 is separated from the left end of the steel pipe, and the right end of the steel pipe is separated from the cover frame 11. The operator releases the fixation of the clamp 2 to the steel pipe and removes the steel pipe. When it is necessary to replace the welding rod on the welding gun 13, the operator rotates the threaded rod 17 to disengage the threaded rod 17 from the slot 20, and the threaded rod 17 is separated from the fixation to the sealing plate 14. The sealing plate 14 is rotated to make the sealing plate 14 separate from the obstruction of the cover frame 11, and the welding gun 13 is taken out and the welding rod is replaced.

[0026] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
