The fixed plate 15 is fixed on the second bottom plate 17, and the left side of the hydraulic rod 16 is fixedly connected to the connecting frame 2. The hydraulic rod 16 pushes the telescopic rod outward, driving the connecting frame 2 to move outward at the same time. The top of the connecting frame 2 is fixedly connected to a slider 3, and the inner side of the slider 3 is slidably connected to a slide bar 4. The connecting frame 2 drives the slider 3 to move left and right on the slide bar 4. The slide bar 4 is fixedly connected to the left and right opposite first fixed plates 14. The first fixed plate 14 fixes the slide bar 4 on the device, increasing the stability of the device. The top of the slider 3 is fixedly connected to a clamping arm 6, and the clamping arm 6 moves left and right on the slide bar 4 through the slider 3, thereby realizing the clamping and fixing of the steel. The front end of the clamping arm 6 is fixedly connected to a front and rear opposite fixed frame 5, and the front end of the fixed frame 5 is fixedly connected to a rack 27, and the fixed frame 5 fixes the rack 27 on the clamping arm 6.

[0030] A fixing column 22 is fixedly connected to the top of the first base plate 1. The fixing column 22 supports the first base plate 1 to prevent the welding platform from tipping over due to unstable center of gravity. A pulley 23 is rotatably connected to the top of the fixing column 22. The pulley 23 ensures that the second base plate 17 can rotate smoothly on the fixing column 22.

[0031] A connecting tube 8 is fixedly connected to the rear end of the upper side of the first bottom plate 1 , and a laser generator 10 is fixedly connected to the upper end of the connecting tube 8 .

[0032] A cooling water tank 11 is fixedly connected to the inner side of the front end of the connecting pipe 8. The cooling water tank 11 is arranged at a position where the heat of the welding head is more concentrated, ensuring that the welding head can be efficiently cooled. A laser emitting port 12 is fixedly connected to the outer side of the front end of the connecting pipe 8. The laser generated in the laser generator 10 is emitted through the laser emitting port 12 through the connecting pipe 8, thereby achieving the heating of the welding material and the welding of the steel.

[0033] A water outlet pipe 9 is fixedly connected to the left side of the rear end of the cooling water tank 11 , and a water pump 21 is fixedly connected to the bottom end of the water outlet pipe 9 . The water pump 21 sucks out the used cooling water in the cooling water tank 11 through the water outlet pipe 9 .

[0034] A connecting pipe 25 is fixedly connected to the upper rear end of the water pump 21, and a cooling box 24 is fixedly connected to the lower rear end of the connecting pipe 25. The cooling water pumped out by the water pump 21 is transported into the cooling box 24 through the connecting pipe 25, and the heated cooling water is cooled down again by the cooling box 24.

[0035] A water inlet pipe 7 is fixedly connected to the rear end of the upper side of the cooling box 24. The cooling water in the cooling box 24 is transported back to the cooling water tank 11 through the water inlet pipe 7 by the water pump 21. A support frame 28 is fixedly connected to the lower side of the water inlet pipe 7. The support frame 28 supports and fixes the water inlet pipe 7, the connecting pipe 8 and the water outlet pipe 9.

[0036] The rear end of the slide rod 4 is slidably connected to a limit device 26, and a pulley 23 is provided on the limit device 26 to ensure that the rack 27 can move smoothly on the device. The inner side of the rack 27 is meshed with the first gear 13. The rack 27 drives the first gear 13 to rotate by moving left and right, thereby driving the rack 27 at the other end to move left and right, so that the two clamping arms 6 can move at the same time.

[0037] Working principle: When the device is running, the hydraulic rod 16 first pushes the telescopic rod outward, driving the connecting frame 2 to move outward. Because the slider 3 and the clamping arm 6 are fixedly connected to the connecting frame 2, the connecting frame 2 drives the slider 3 and the clamping arm 6 to move outward together. At the same time, the rack 27 is fixedly connected to the clamping arm 6 through the fixed frame 5, so it moves outward together with the connecting frame 2, the slider 3 and the clamping arm 6. The rack 27 also drives the first gear 13 to rotate at the same time, and the other end of the first gear 13 is also meshed with another rack 27, thereby driving the other end structure to which it is fixedly connected to move toward the other outer end, thereby realizing the clamping function of the steel. Then the motor 20 outputs power to drive the third gear 19 to rotate, and then the third gear 19 drives the second gear 18 to continue to rotate, thereby driving the second bottom plate 17 at the top of the second gear 18 to rotate together, thereby realizing the rotation function of the device, and then the water pump 2 1 starts to operate, the water pump 21 draws the used cooling water from the water outlet pipe 9, and transports it into the cooling box 24 through the connecting pipe 25. The used cooling water is cooled again by the cooling box 24 to ensure the temperature of the cooling water and achieve efficient water cooling of the welding joint. After that, the cooling water treated by the cooling box 24 is pressurized by the water pump 21 and enters the water inlet pipe 7. Through the transportation of the water inlet pipe 7, the cooling water is injected from the front end of the cooling water tank 11. After the welding joint is cooled, it is again pumped out from the water outlet pipe 9 at the rear end of the cooling water tank 11 by the water pump 21, thereby realizing the recycling of cooling water. In addition, the cooling water is injected from the front end of the cooling water tank 11 and pumped out from the rear end, so that the cooling water flows in the cooling water tank 11 to form a cycle, and new cooling water is always guaranteed to enter, and the used cooling water can be pumped out of the cooling water tank 11 in time to ensure the reliability of the cooling device.
