A fan 18 is fixedly connected to the lower end of the connecting pipe 17, and a motor 19 for driving is provided on one side of the fan 18.

[0024] In an optional embodiment: the fixing plate 2 is fixedly connected to the center of the upper surface of the operating table 1, and a notch equal to the welding material is opened at the center, which is convenient for fixing the material and avoiding material displacement during welding. There are four groups of support rods 3 fixedly connected around the operating table 1, and the upper ends of the four groups of support rods 3 are all provided with cylinders 4, and the four groups of support rods 3 are equal in size. The upper ends of the support rods 3 fix the cylinders 4, making the cylinders 4 more stable when in use.

[0025] In an optional embodiment: the output end of the cylinder 4 is connected to the fixing ring 5 through a push rod, and its four groups of fixing rings 5 ​​are matched, and the inner diameter matches the outer diameter of the welding material. When the welding material is put down, the cylinder 4 pushes the fixing ring 5 to shrink toward the center, thereby fixing the material, thereby improving the stability of the material splicing during welding.

When used, the welding material is placed inside the first guide ring 6, and the first guide ring 6 applies a fixed force to it, thereby further improving the stability during welding. At the same time, the four groups of connecting frames 7 fix the first guide ring 6, thereby preventing the first guide ring 6 from shifting and causing the welding position to shift.

[0027] In an optional embodiment: the second guide ring 9 is movably connected to the lower end of the first guide ring 6 through two groups of electric push rods 8, the electric push rods 8 are fixedly connected to the electric push rods 8, and the electric push rods 8 extend to the lower end of the second guide ring 9, the welder 10 is fixedly connected to one side of the upper end of the electric push rods 8, and the heating gun 11 and the welder 10 are in a horizontal facing vertical plane, and the second guide ring 9 is lowered by the electric push rods 8. During welding, the welding machine 10 will remove oil stains from the unwelded areas before welding with the heating gun 11, and preheat the welding materials, thereby improving the welding quality. During welding, the heating gun 11 heats the position after welding, thereby reducing the stress at the weld, so that the quality of the welding is more stable.

[0028] In an optional embodiment: the positioning buckle 12 is provided inside the turntable at the upper end of the motor 19, and the turntable is located at the lower end of the fixed plate 2. A notch matching the outer diameter of the second guide ring 9 is provided on the upper surface of the fixed plate 2, and an empty hole for exhausting air is provided on the inner side of the notch. The push block 14 is movably connected to the inside of the positioning hole 13, and is connected to the inside of the turntable through a spring 15. When the second guide ring 9 descends, the electric push rod 8 extends to the lower end of the second guide ring 9, and the size of the second guide ring 9 corresponds to the notch, so that when the second guide ring 9 descends, it will enter the inside of the notch, and the extended electric push rod 8 will enter the inside of the positioning hole 13. If the second guide ring 9 does not enter the inside of the notch or the electric push rod 8 does not enter the inside of the positioning hole 13, the equipment will not perform welding. After the connection is completed, the welding material is put in through the fixed ring 5. Because the positioning buckle 12 is fixedly connected to the second guide ring 9, the second guide ring 9 will descend and the connection will be completed, which will cause the positioning buckle 12 to stay at the upper end of the fixed plate 2, thereby welding. When the material falls, the welding position with the lower welding material can be accurately found through the position of the positioning buckle 12, thereby avoiding the problem of error in manual measurement. At this time, the motor 19 will drive the turntable to rotate. Because the electric push rod 8 is connected to the positioning hole 13, and the first guide ring 6 and the connecting frame 7 are movably connected, when the motor 19 rotates the turntable, it will drive the electric push rod 8 to move through the positioning hole 13. When the electric push rod 8 moves, it will drive the first guide ring 6 and the second guide ring 9 to rotate. At this time, the second guide ring 9 moves inside the slot, so that it will not cause position deviation during rotation. During rotation, the heating gun 11 will perform preliminary decontamination on the welding point. The welding machine 10 will not start until the heating gun 11 rotates one circle, so as to weld around the welding point. During welding, the second guide ring 9 is positioned and guided by the slot, and the electric push rod 8 can rotate and weld by entering the positioning hole 13, so that the accuracy of each welding is ensured during the welding time, thereby improving the quality of welding.

[0029] In an optional embodiment, the connection between the push block 14 and the valve 16 is an upper and lower set of clamping plates, the valve 16 is located between the two sets of clamping plates, the connecting pipe 17 is connected to the empty hole of the upper turntable, the valve 16 controls the switch inside the connecting pipe 17, the fan 18 is fixedly connected to the lower end of the turntable through the connecting pipe 17, the motor 19 is located at the center of the lower end of the operating table 1, and is connected to the turntable through a rotating rod. The outer cover for protection is provided on the periphery of the motor 19. After the electric push rod 8 enters the positioning hole 13, the electric push rod 8 will push the push rod 8. The block 14 descends. When the push block 14 descends, due to the connection between the push block 14 and the valve 16, the push block 14 will toggle the valve 16 for a small flip. After the valve 16 flips, the inside of the connecting pipe 17 will be unblocked, so that the fan 18 will absorb the fume generated during welding through the empty hole at the upper end, thereby reducing pollution. After the welding is completed, the electric push rod 8 rises with the force of the spring 15 to automatically reset the push block 14, so that the push block 14 will drive the valve 16 to flip and close again, thereby closing the suction.

[0030] Working principle and process: Before welding, the welded plate is placed inside the fixed plate 2 for fixation. After the fixation is completed, the electric push rod 8 is started to push the second guide ring 9 down. When the second guide ring 9 is descending, ensure that the second guide ring 9 enters the inside of the slot, and the electric push rod 8 enters the inside of the positioning hole 13. After preparation is completed, the welding material is placed through the fixed ring 5. When it contacts the welded plate, the welding position is accurately found through the positioning buckle 12. Before welding, the motor 19 will drive the turntable to drive the heating gun 11 to decontaminate and preheat the weld. The welder 10 will not start to weld until the heating gun 11 rotates one circle. At the same time, when the welder 10 is welding, the heating gun 11 will continue to preheat the unwelded part as the second guide ring 9 rotates, and perform secondary heating on the welded position to eliminate stress. At the same time, during welding, because the electric push rod 8 enters the inside of the positioning hole 13, it pushes the push block 14 to open the valve 16, so that the fan 18 can absorb the smoke generated during welding.

[0031] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
