[0025] The adjustable air cooling assembly 7 comprises a fan 701, the fan 701 is arranged at the rear of the upper end of the limiting stake 2, the upper end of one side of the limiting stake 2 is provided with a mounting plate 702, the mounting plate 702 is provided with two groups, the opposite surfaces of the two groups of mounting plates 702 are provided with a blowing pipe 703 through a rotating shaft, the outer surface of the blowing pipe 703 is provided with a booster nozzle 704, the booster nozzle 704 is provided with a plurality of groups, one end of one of the mounting plates 702 is provided with a motor 706, the motor 706 is used to drive one end of the blowing pipe 703 to rotate around the axis, and the output end of the fan 701 is provided with a gas conveying pipe 705.

[0026] When the workpiece is placed on the surface of the workbench 4, the two groups of electric push rods 11 on the fixing frame 8 drive the telescopic action of the clamping plates 10, and each group of clamping plates 10 uniformly applies clamping force through two groups of telescopic rods 9, so as to clamp the workpiece by moving close to each other. The operator can set appropriate clamping force according to the material, shape and size of the workpiece to clamp it. When the sliding groove 3 on the limiting pile 2 cooperates with the sliding block 41 on both sides of the workbench 4, the workbench 4 can be stably guided, and the workbench 4 can only move in the linear direction of the sliding groove 3, so as to ensure the linearity and stability of the movement of the workbench 4.

During the laser cutting process, the cutting path is usually complex and changeable, especially when cutting irregular-shaped workpieces.

Further, the air conveying pipe 705 penetrates the inner cavity of the mounting plate 702, and the inner cavity of the mounting plate 702 leaves a space for air flow, so that the process of transmitting cooling air to the air supply pipe 703 is more stable, and the cooling air can enter the relatively closed space of the inner cavity of the mounting plate 702.
