[0027] When the filter drive mechanism is operating, the first dual-shaft motor 29 drives the exhaust fan 30, generating suction. The exhaust fan 30 and the exhaust pipe 31 work together to extract air from the flow trough 32, thereby creating suction in the air inlet 33 to treat the welding fumes. Simultaneously, the first dual-shaft motor 29 rotates the crankshaft 26. This movement, coupled with the transmission assembly, drives the compression block 21, which compresses the collected debris into blocks, thereby reducing the space occupied by the debris.

When the drive motor 4 is working, it will drive the No. 1 screw rod 5 to rotate, thereby adjusting the position of the No. 1 slider 6. The position of the welding head 8 can be adjusted by the telescopic rod 7. After the welding head 8 is moved to the welding location, the telescopic rod 7 is an electric push rod that can adjust the height of the welding head 8. After the welding head 8 contacts the welding location, the steel structure can be welded.

[0030] Embodiment 8 differs from embodiment 7 in that a support mechanism for supporting the welded portion of the steel structure is provided inside the workbench 1.

The movement of the top plate 39 through the connecting rod 41 will push the position of the load-bearing plate 42 to move, and then the position of the load-bearing plate 42 can be adjusted to adapt to the steel structures in different positions for support, so that the steel structure can maintain stability for welding, thereby improving the welding quality.

[0032] Example 9 is different from Example 1 in that Figure 1As shown, the adjustment mechanism includes a chute 9, an adjusting screw 10, a power motor 11 and a sliding block 12. The chute 9 extends horizontally along the length of the workbench and is arranged on the workbench 1, and the adjusting screw 10 is rotatably arranged in the chute 9. The power motor 11 is fixedly arranged inside the chute 9, and one end of the adjusting screw 10 is fixedly connected to the output end of the power motor 11, and the other end of the adjusting screw 10 is rotatably connected to the chute 9 through a bearing.

In this embodiment, there are two groups of adjusting screws 10 and power motors 11. When the power motor 11 is working, it will drive the adjusting screw 10 to rotate. The rotation of the adjusting screw 10 will adjust the position of the sliding block 12. The position of the square frame 13 can be adjusted by the sliding block 12. Then, by cooperating with the two groups of adjusting screws 10 and the power motor 11, the position of the square frame 13 can be adjusted, and the position of the adjustable clamped steel structure can be welded.

[0033] Example 10 is different from Example 1 in that Figure 3 As shown, the clamping mechanism includes a second double-output shaft motor 14, a drive screw 15, a drive block 16 and a clamping plate 17.

The drive block 16 is symmetrically arranged inside the square frame 13, and the drive screw 15 is threadedly connected to the drive block 16. The drive block 16 is fixedly connected to the corresponding clamping plate 17. When the clamping mechanism is used to clamp the welded steel structure, the second double-output shaft motor 14 is operated to drive the drive screw 15 to rotate. When the drive screw 15 rotates, the position of the drive block 16 is adjusted. The position of the clamping plate 17 can be adjusted by the drive block 16. Then, the steel structure can be clamped by moving the clamping plate 17.

[0034] Example 11 is different from Example 1 in that it is a welding method for a steel structure positioning welding device, comprising: S1. After the workpiece to be welded is fixedly clamped by the clamping mechanism, the adjustment mechanism is then moved to adjust the position of the square frame 13.

[0035] The working principle of the present invention is as follows: First, when using the steel structure positioning welding device to weld the steel structure, the second double-output shaft motor 14 drives the drive screw 15 to rotate. When the drive screw 15 rotates, the position of the drive block 16 is adjusted. The position of the clamping plate 17 can be adjusted by the drive block 16, and the steel structure can be clamped by moving the clamping plate 17. The power motor 11 drives the adjustment screw 10 to rotate. The rotation of the adjustment screw 10 adjusts the position of the sliding block 12. The position of the square frame 13 can be adjusted by the sliding block 12. The position of the square frame 13 can be adjusted by the cooperation of the two sets of adjustment screws 10 and the power motor 11. When the square frame 13 moves, it can drive the steel structure to move through the clamping mechanism, so that the two steel structures are connected at the weld. The load-bearing plate 42 can be used to support the welding part of the steel structure. The operation of the servo motor 38 will drive the adjustment screw 40 to rotate. When the adjustment screw 40 rotates, the top plate 39 will move. The movement of the top plate 39 will push the position of the load-bearing plate 42 through the connecting rod 41, and then the position of the load-bearing plate 42 can be adjusted to adapt to the steel structure in different positions. The steel structure can maintain stability during welding, thereby improving the stability of the steel structure. The operation of the drive motor 4 will drive the No. 1 screw 5 to rotate, and then the position of the No. 1 slider 6 can be adjusted. The position of the welding head 8 can be adjusted through the telescopic rod 7, and the welding head 8 can be moved to the welding location. The telescopic rod 7 is an electric push rod that can adjust the height of the welding head 8. After the welding head 8 contacts the welding location, the steel structure can be welded, achieving the purpose of rapid welding of the steel structure.

[0036] During the welding of steel structures, the first dual-axis motor 29 is controlled to drive the exhaust fan 30 to work. The exhaust fan 30 generates suction when it is working. The exhaust fan 30 and the exhaust pipe 31 cooperate to extract the air inside the flow groove 32, thereby generating suction at the air inlet 33. The smoke particles generated during welding will follow the air flow into the flow groove 32. The particles carried by the air will be filtered and intercepted by the filter plate 36, thereby achieving the purpose of air filtration and purification, effectively avoiding the impact on the surrounding environment. At the same time, when the first dual-axis motor 29 is working, it will drive the crankshaft 26 to rotate. When the crankshaft 26 rotates, it will drive the sliding plate 25 to move through the drive plate 27. The movement of the sliding plate 25 will drive the drive shaft 24 to slide inside the cylinder 23, and then the compression block 21 can be driven to move through the drive shaft 24. The compression block 21 can squeeze the stored debris into blocks, thereby reducing the space occupied by the debris.
