The storage groove 45 is pulled to move the storage groove 45 to the outside, and then the waste can be removed.

[0053] Working principle: First, when welding the sheet metal parts using the welding tooling for sheet metal processing, after placing the sheet metal part on one side of the positioning block 11, the position of the positioning block 11 can be adjusted by moving the adjustment mechanism. After the positioning block 11 moves, the position of the sheet metal part can be limited and clamped. When the stepper motor 22 is working, it will drive the bidirectional screw rod 7 to rotate. The rotation of the bidirectional screw rod 7 will move the slider 6. When the slider 6 moves, it will drive the support block 4 to move. The support block 4 will be guided by the guide rod 34 to make the support block 4 move smoothly. The movement of the support block 4 can adjust the position of the clamping assembly, and then the clamping assembly can be used to The position of the sheet metal parts is adjusted to align the welding points of the two sheet metal parts, and then the arc welding can be used to weld the sheet metal parts. When the welding angle of the welded sheet metal parts needs to be adjusted, the driving motor 20 is operated to adjust the angle of the clamping assembly, thereby facilitating the adjustment of the angle of the sheet metal parts and facilitating the welding of the sheet metal parts. Accurately adjusting the angle of the sheet metal parts can ensure that the seam alignment during welding is more precise and reduce welding defects such as incomplete welding or misalignment. Appropriate angle adjustment can ensure the reasonable thickness and uniformity of the weld, thereby improving the strength and durability of the welded joint and simplifying the welding preparation work. The operation makes the welding process faster and more efficient, reduces the complexity of operation, and after welding, good angle adjustment can make subsequent processing steps such as grinding and painting smoother, thereby improving the overall quality of the final product. When adjusting the position of the support block 4, a through hole is provided on the bottom plate 1. When welding the sheet metal parts, the waste generated by welding the sheet metal parts will fall into the storage groove 45 through the through hole. When the collected impurities are removed, the waste is prevented from affecting the surrounding environment. It is also necessary to manually clean it with the help of tools, which is inconvenient. Pull the storage groove 45 to move the storage groove 45 to the outside, and then the waste can be removed. The exhaust fan 42 is operated to extract the air inside the purification box 35, which will generate suction in the square slot 37. The air flow will carry the smoke generated by the sheet metal welding and will flow into the square slot 37. The smoke will flow into the purification box 35 through the exhaust pipe 36. The particulate matter can be adsorbed and intercepted by the filter plate 40, thereby achieving the purpose of purifying the smoke. Then, after the air flows into the bellows 41, the wind flow discharged by the exhaust fan 42 enters the exhaust pipe 43, and the air will flow to the outside through the exhaust pipe 43 to avoid affecting the surrounding environment.
