[0022] (IV) The cutting machine is provided with an arc scraper. When the arc scraper rotates with the output end of the driving motor, centrifugal force is generated. When the large particles of waste contained in the smoke being inhaled pass through the arc scraper, they will be thrown into the bypass pipe under the action of centrifugal force.

The operator can manually rotate the rotating ring according to actual observation needs, thereby driving the annular perspective plate to rotate in the shielding shell and adjusting the position of the annular perspective plate.

[0025] (VII) The cutting machine is provided with a cleaning component. When the annular perspective plate rotates, the outer side of the rubber wiping plate contacts the outer side of the annular perspective plate, and the rotation of the annular perspective plate causes the surface of the annular perspective plate to slide relative to the rubber wiping plate.

When the limit block moves toward the direction close to the rubber wiping plate, the compression spring will be compressed. The elastic force generated by the compression spring will be transmitted to the rubber wiping plate through the connecting block, so that the rubber wiping plate slides outward along the shell, and the pressure on the annular perspective plate is increased, thereby enhancing the wiping effect. It is suitable for the situation where there are many and stubborn stains on the surface of the annular perspective plate. BRIEF DESCRIPTION OF THE DRAWINGS

It is suitable for the situation where there are many and stubborn stains on the surface of the annular perspective plate 302.

[0042] Working principle:

[0043] When in use, in the multi-angle adjustable laser cutting machine for automotive parts, the base 1 serves as the supporting foundation of the entire equipment, and the fixed platform 2 fixed on the top by bolts is used to place the automotive parts to be cut, and a fixing clamp can be installed on the fixed platform 2 to fix the automotive parts, and a motor that can drive the horizontal screw 4 to rotate is installed on the outer side of the base 1, and a motor that can drive the vertical screw 6 to rotate is installed on the top of the hollow column 5.

[0044] Under the guidance of the guide rod 3, when the transverse screw rod 4 rotates, the hollow column 5 will make a transverse linear motion along the guide rod 3, thereby adjusting the position of the laser cutting head 12 in the transverse direction. When the vertical screw rod 6 rotates, the adjustment block 7 will make a vertical linear motion along the inner wall of the hollow column 5, thereby driving the fixed frame 8, the telescopic cylinder 9, the sliding frame 10, the deflection plate 11 and the laser cutting head 12 to move in the vertical direction as a whole, thereby realizing height adjustment.

[0045] When the telescopic cylinder 9 is working, it can push the sliding frame 10 to slide on the inner walls on both sides of the fixed frame 8, realize the telescopic movement of the laser cutting head 12, and further adjust the cutting position. The deflection plate 11 is rotatably connected to the outer side of the sliding frame 10. The servo motor installed on the outer side of the sliding frame 10 can make the deflection plate 11 rotate around the rotation point, thereby driving the laser cutting head 12 to deflect at an angle to meet the cutting requirements of automotive accessories at different angles.

[0046] The bottom of the protective shell 131 of the protective device 13 is fixedly connected to the top of the deflection plate 11. Its main function is to protect the laser cutting head 12 and process the smoke and waste generated during the cutting process. After the drive motor 139 is started, its output end drives the fan blades 134 and the arc scraper 135 to rotate. When the fan blades 134 rotate, an airflow will be formed inside the protective shell 131, and the smoke generated during the cutting process will be sucked into the protective shell 131 through the connecting pipe 132, thereby reducing the diffusion of smoke in the working area and reducing the risk of operators inhaling harmful substances.

[0047] The arc scraper 135 is provided, and when the arc scraper 135 rotates with the output end of the driving motor 139, centrifugal force is generated. When the large waste particles contained in the smoke being sucked pass through the arc scraper 135, they are thrown into the bypass pipe 137 under the action of centrifugal force. This can prevent the large waste particles from entering the activated carbon cartridge 136, and prevent them from clogging the activated carbon cartridge 136 prematurely and affecting the adsorption effect.

[0048] When it is necessary to clean the impurities collected in the bypass pipe 137 , the scraper frame 138 is taken out from the bypass pipe 137 , and the scraper frame 138 will take out the impurities collected in the bypass pipe 137 , thereby cleaning the bypass pipe 137 .

[0049] The main function of the shielding shell 301 in the shielding mechanism 133 is to prevent the smoke generated during cutting from diffusing outward. The annular perspective plate 302 adopts radiation-proof glass to protect the eyes. The rotating ring 303 is used to drive the annular perspective plate 302 to rotate in the shielding shell 301. The operator can manually rotate the rotating ring 303 according to actual observation needs, thereby driving the annular perspective plate 302 to rotate in the shielding shell 301 and adjusting the position of the annular perspective plate 302.

[0050] The cleaning assembly 304 is used to wipe the surface of the rotating annular perspective plate 302. When the annular perspective plate 302 rotates, the outer side of the rubber wiping plate 402 contacts the outer side of the annular perspective plate 302, and the rotation of the annular perspective plate 302 causes the surface of the annular perspective plate 302 to slide relative to the rubber wiping plate 402. The rubber wiping plate 402 is soft and has a certain friction force, which can effectively wipe off the dust attached to the surface of the annular perspective plate 302, the debris generated by cutting, and other stains, thereby maintaining the cleanliness of the annular perspective plate 302, so that the operator can clearly observe the cutting of the automotive parts by the laser cutting head 12 through the observation window 305.

[0051] By rotating the knob 404 on the outside of the fixed cylinder 403, the threaded rod 405 rotates, thereby adjusting the position of the limit block 406 on the annular limit frame 407. When the limit block 406 moves toward the direction close to the rubber wiping plate 402, the compression spring 408 is compressed. The elastic force generated by the compression spring 408 is transmitted to the rubber wiping plate 402 through the connecting block 409, so that the rubber wiping plate 402 slides outward along the shell 401, and the pressure on the annular perspective plate 302 is increased, thereby enhancing the wiping effect. It is suitable for the situation where there are many and stubborn stains on the surface of the annular perspective plate 302.
