[0029] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0030] like Figure 1-3 As shown, an automatic metal sheet welding machine includes a worktable 1, a fixed frame 2, a welding mechanism and a clamping mechanism, wherein the fixed frame 2 is fixed on the worktable.

[0031] Specifically, the clamping mechanism includes a connecting plate 31, a first driving component 32, a connecting shaft 33, a pressure plate 34, protective components, and limiting components. The connecting plate 31 is fixed on the fixed frame. The first driving component 32 is a conventional hydraulic cylinder, which is fixed on the connecting plate and can drive the connecting shaft to move up and down. The connecting shaft 33 is fixed on the output end of the first driving component. The pressure plate 34 is rotatably connected to the connecting shaft. When fixing the plate, the plate is first placed on the worktable, and then the pressure plate is rotated to a suitable position according to the processing needs and the shape of the plate. Then, the first driving component is started to move the pressure plate down, thereby completing the fixing of the plate. By adjusting the position of the pressure plate, more processing positions and plate shapes can be accommodated.

[0032] Specifically, the limiting assembly includes a connecting hole 311, a mounting hole 331, a first elastic element 35, a limiting rod 36, a ball bearing 37, and a bearing 38. The connecting hole 311 is formed on the pressure plate and allows the connecting shaft to be inserted. The mounting holes 331 are evenly distributed on the outer wall of the connecting shaft. The first elastic element 35 is a spring, one end of which is fixed in the mounting hole. One end of the limiting rod 36 is fixed to the end of the first elastic element and can slide relative to the inner wall of the mounting hole. The ball bearing 37 is rotatably connected to the end of the limiting rod, and the inner wall of the connecting hole is provided with a groove for the ball bearing to be inserted. The bearing 38 is fixed in the connecting hole and connected to the connecting shaft. By pushing the ball bearing into the groove through the first elastic element, the rotation of the pressure plate can be limited to a certain extent, preventing the pressure plate from rotating after the position adjustment is completed.

[0033] Specifically, the protective assembly includes a guide post 391, a second elastic element 392, a fixing plate 393, and an elastic plate 394. One end of the guide post 391 is fixed to the pressure plate. The second elastic element 392 is a spring, which is sleeved on the guide post. One end of the second elastic element is connected to the pressure plate, and the other end is connected to the fixing plate. The fixing plate 393 is fixed to the end of the second elastic element, and the fixing plate is provided with a guide hole 3931 for the guide post to be inserted. When fixing the plate, the second elastic element can play a buffering and protective role. The elastic plate 394 is fixed to the bottom surface of the fixing plate.

[0034] Specifically, the welding mechanism includes a mounting block 41, a push rod 42, a welding head 43, and a drive assembly for moving the welding head. The push rod 42 is a conventional electric push rod, with one end fixed to the mounting block; the welding head 43 is fixed to the end of the push rod.

[0035] Specifically, the drive assembly includes a guide rail 441, a first threaded rod 442, a guide rod 443, a drive wheel 444, a transmission wheel 445, a second drive component 446, a slider 447, a mounting plate 448, a second threaded rod 449, and a third drive component 440 that drives the second threaded rod to rotate. The slider 447 has a slot that mates with the fixed frame, allowing it to slide relative to the fixed frame. The mounting plate 448 is symmetrically fixed to the fixed frame. The two ends of the second threaded rod 449 are rotatably connected to the mounting plate, and the slider is screwed onto the second threaded rod. The third drive component 440 uses a conventional motor, and its output shaft is connected to the third threaded rod. The guide rail 441 is fixed to the slider. The two ends of the first threaded rod 442 are respectively rotatably connected to... On the guide rail; the two ends of the guide rod 443 are fixed on the guide rail respectively; the drive wheel 444 is fixed on the first threaded rod; the second drive component 446 is a conventional motor, which is fixed on the guide rail; the transmission wheel 445 is fixed on the output shaft of the second drive component; the mounting block is provided with a threaded hole that mates with the first threaded rod, and the mounting block is provided with a round hole that mates with the guide rod. When it is necessary to move the welding head back and forth, the third drive component is activated to drive the second threaded rod to rotate. The rotation of the second threaded rod will drive the slider to move back and forth, and thus drive the welding head to move back and forth. When it is necessary to move the welding head left and right, the second drive component is activated to drive the first threaded rod to rotate. The rotation of the second threaded rod will drive the mounting block to move left and right, and thus drive the welding head to move left and right.
