The water circulation mechanism supplies water to the water inlet 8 of the hollow ring 7, and the water flow in the hollow ring 7 is sprayed downward from the water curtain nozzle 11 through the connecting pipe 12 To form an annular water curtain, the water curtain nozzle 11 is rotated in advance to adjust the angle, and the size of the annular water curtain can also be changed. When cutting, when high-temperature sparks splash outwards, they will be intercepted by the water curtain and quickly cool down. Because the water flow always flows downwards, the water flow will exert a downward force on the sparks, making it difficult for the sparks to penetrate the water curtain, but will be moved down by the water. Wash away to avoid the adverse effects of high temperature sparks. In addition, the water flow can also cool the sheet metal parts to avoid the expansion and deformation of the cutting opening caused by the residual heat during cutting, which affects the cutting accuracy.

The jacking cylinder 401 can drive the clamping plate 402 to move left and right, and the pressing down cylinder 404 can drive the pressing plate 405 to move up and down. By adjusting the positions of the clamping plate 402 and the pressing plate 405, sheet metal parts of different shapes and sizes can be fixed, which has a wide range of applications. Driven by an air cylinder, the force is stable and the fixing effect is good.
[0031] A rubber layer 406 is provided on the side of the splint 402 close to the diversion hole 5 and under the pressure plate 405. The rubber layer 406 can protect the contact surface of the sheet metal part to avoid deformation and damage of the sheet metal part.
[0032] The connecting seat 10 is U-shaped, the water curtain nozzle 11 is arranged in the U-shaped mouth of the connecting seat 10, and the water curtain nozzle 11 is hinged to the connecting seat 10.
[0033] The connecting rod 9 is a telescopic rod, and its two ends are respectively fixedly connected with the hollow ring 7 and the clamp 6. When the clamp 6 is sleeved on different laser cutting heads 3, the distance between the clamp 6 and the hollow ring 7 is adjusted by the expansion and contraction of the connecting rod 9.
