The limit screw 12 can limit the sliding range of the longitudinal slider 6 on the T-shaped bracket 4, and at the same time can clamp the longitudinal slider 6 to prevent it from sliding too far and falling. The transverse slider 5 can determine the position in the longitudinal direction. After the transverse and longitudinal positions are determined, the laser cutting head 22 can perform cutting, and the clamping device 31 can clamp and release the sheet metal.

[0026] Reference Figure 1 , Figure 2 A heat dissipation base 13 is installed on the top of the water tank 15. The top of the heat dissipation base 13 is composed of a plurality of triangular brackets. A plurality of water leakage holes 14 are opened on the top of the heat dissipation base 13. A filter device 3 is slidably connected to the middle of one side of the base 1. The filter device 3 includes a surrounding plate 25. A filter net 26 is installed in the middle of the surrounding plate 25. A handle is fixedly connected to one side of the surrounding plate 25.

[0027] Specifically, the heat dissipation base 13 can be used when cutting large sheet metal parts. The sheet metal parts can be directly placed on it for cutting. There is a triangular bracket on it to play a role in heat dissipation. This technology is a prior art and will not be explained. The leakage port 14 can allow the coolant sprayed from the nozzle 19 to flow into the water tank 15. The filter device 3 can filter out the debris of the cut sheet metal parts, so that the water pump 7 will not be damaged when pumping water. The filter device 3 can be taken out by pulling the handle to clean up the debris.

[0028] Reference Figure 1 , Figure 3 The clamping device 31 includes a fixed block 9, the bottom of the fixed block 9 is fixedly connected to the two sides of the top of the base 1, and the two ends of one side of the fixed block 9 are rotatably connected to the guide rods 10. A motor 8 is installed on one side of the fixed block 9, and the output end of the motor 8 is fixedly connected to the screw 11. The two ends of the screw 11 are rotatably connected to the middle part of one side of the fixed block 9. The middle part of the screw 11 is threadedly connected to the fixed plate 28, and the top of the fixed plate 28 is fixedly connected to the clamping plate 20.

[0029] Specifically, the fixing block 9 can support the guide rod 10 and the screw 11. The rotation of the motor 8 can drive the screw 11 to rotate. The rotation of the screw 11 can drive the fixing plate 28 to move above it, so that the clamping plate 20 can clamp and release the sheet metal.

[0030] Reference Figure 2 , Figure 4A groove 29 is provided on the inner side of the bottom of the support frame 2, a water pump 7 is installed on one side of the base 1, a first pipe 16 is installed on the top of the water pump 7, a third pipe 21 is installed on the bottom of the water pump 7, a first hose 27 is installed on one end of the third pipe 21, a nozzle 19 is installed on the other end of the first hose 27, the top of the nozzle 19 is installed on the bottom of the horizontal slider 5, a gas purifier 23 is installed on one side of the base 1, a second pipe 17 is installed on the top of the gas purifier 23, a blower 24 is installed on the bottom of the gas purifier 23, a second hose 30 is installed on one end of the second pipe 17, a cover body 18 is installed on the other end of the second hose 30, and one end of the cover body 18 is installed on one side of the horizontal slider 5.

[0031] Specifically, the groove 29 can provide activity space for the first hose 27 and the second hose 30. The third pipe 21 is connected to the bottom of the water tank 15, and the coolant can be pumped out under the action of the water pump 7. The coolant is sprayed out by the nozzle 19 through the first pipe 16 and the first hose 27, so that the cut sheet metal parts are cooled down. The blower 24 can make the cover body 18 send the smoke generated when the sheet metal parts are cut through the second hose 30 and the second pipe 17 to the gas purifier 23 for filtering and purification, and then the filtered and purified gas is discharged through the output end of the blower 24. This can protect the environment and protect the health of the staff in the workshop during long-term work.

[0032] Working principle: First, the rotation of the motor 8 can drive the screw 11 to rotate, and the rotation of the screw 11 can drive the fixed plate 28 to move above it, so that the clamping plate 20 can be loosened, and the sheet metal part is placed on the clamping plate 20. The rotation of the motor 8 can make the clamping plate 20 clamp the sheet metal part. To cut large sheet metal parts, you only need to place the sheet metal part on the heat dissipation base. Then, push the longitudinal slider 6 to move above the T-shaped bracket to determine the position in the horizontal direction of the cutting. The limit screw 12 can limit the sliding range of the longitudinal slider 6 on the T-shaped bracket 4, and at the same time, it can also clamp the longitudinal slider 6 to prevent it from sliding too far and falling. The horizontal slider 5 can determine the position in the longitudinal direction. After determining the horizontal and vertical positions, the laser cutting head 22 can cut Cutting, when cutting, turn on the blower and the water pump, so that the nozzle 19 can spray coolant for cooling and the cover 18 can inhale the smoke for purification. At this time, the coolant sprayed by the nozzle 19 is sprayed onto the sheet metal for cooling and then falls into the leakage port 14 of the heat dissipation base 13, and flows through the leakage port 14 to the filter device 3. At this time, the filter screen 26 will filter the debris of the cut sheet metal in the coolant, and finally flow into the water tank 15, so that the coolant extracted by the water pump 7 in the water tank 15 can be recycled. After the work is completed, pull the handle to pull out the filter device 3, clean the sheet metal debris on the filter screen 26, and return the filter device 3 to its original position after cleaning, and the work is completed.
