[0041] The cleaning assembly 304 comprises a shell 401, an inner wall of the shell 401 is slidingly connected with a rubber wiping plate 402, an outer side of the rubber wiping plate 402 is fixedly connected with a connecting block 409, an outer side of the shell 401 is fixedly connected with the outer side of the shielding shell 301, an outer side of the rubber wiping plate 402 is in contact with an outer side of the annular transparent plate 302, an outer side of the connecting block 409 is slidingly connected with an annular limiting rack 407, an outer side of the annular limiting rack 407 is fixedly connected with a fixing cylinder 403, an outer side of the fixing cylinder 403 is fixedly connected with an outer wall of the shell 401, a side of the connecting block 409 away from the rubber wiping plate 402 is fixedly connected with a compression spring 408, one end of the compression spring 408 away from the connecting block 409 is fixedly connected with a limiting block 406, a center of the limiting block 406 is threadedly connected with a threaded rod 405, an outer side of the threaded rod 405 is fixedly connected with a knob 404, an outer side of the knob 404 is rotationally connected with the outer side of the fixing cylinder 403, an inner wall of the limiting block 406 is slidingly connected with an outer wall of the annular limiting rack 407, and the cleaning assembly 304 is used for wiping the surface of the rotating annular transparent plate 302.

It is suitable for the case that the surface of the annular transparent plate 302 has more stubborn stains.

[0042] Working principle:

[0043] In use, in the multi-angle adjusting laser cutting machine for automobile parts, the base 1 serves as the support basis of the entire device, and the fixed table 2 on the top thereof is used for placing the automobile parts to be cut. The fixed table 2 can be installed with a fixed clamp to fix the automobile parts, and the outer side of the base 1 is installed with a motor that can drive the horizontal lead screw 4 to rotate. The top of the hollow column 5 is installed with a motor that can drive the vertical lead screw 6 to rotate.

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

[0045] When the telescopic air cylinder 9 works, it can push the sliding frame 10 to slide along the inner wall on both sides of the fixed frame 8, so as to realize the telescopic movement of the laser cutting head 12 and further adjust the cutting position. The deflection plate 11 is rotationally connected to the outer side of the sliding frame 10. Through the servo motor installed on the outer side of the sliding frame 10, the deflection plate 11 can be rotated around the rotation point, thereby driving the laser cutting head 12 to deflect in angle, so as to meet the cutting requirements of different angles of automobile accessories.

[0046] The protective shell 131 of the protection 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 handle the smoke and waste generated during the cutting process. After the driving motor 139 is started, its output end drives the fan blade 134 and the arc-shaped scraper 135 to rotate. When the fan blade 134 rotates, an air flow is formed inside the protective shell 131, which sucks the smoke generated during the cutting process into the protective shell 131 through the connecting pipe 132, reduces the diffusion of the smoke in the working area, and reduces the risk of operators inhaling harmful substances.

[0047] Among them, by setting the arc-shaped scraper 135, when the arc-shaped scraper 135 rotates with the output end of the driving motor 139, a centrifugal force is generated. The large-particle waste contained in the sucked smoke will be thrown into the bypass pipe 137 under the action of the centrifugal force when passing through the arc-shaped scraper 135. In this way, large-particle waste can be prevented from entering the activated carbon cylinder 136, so as to prevent it from prematurely clogging the activated carbon cylinder 136 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 of the bypass pipe 137. The scraper frame 138 can take out the impurities collected in the bypass pipe 137, so as to clean the bypass pipe 137.

[0049] The shielding shell 301 in the shielding mechanism 133 mainly prevents the smoke generated during cutting from diffusing outward. The annular perspective plate 302 is made of anti-radiation glass, which plays a role in protecting 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 the 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 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 due to the contact between the outer side of the rubber wiping plate 402 and the outer side of the annular perspective plate 302. The rubber wiping plate 402 is soft and has a certain friction, which can effectively wipe off the dust, cutting debris and other stains attached to the surface of the annular perspective plate 302, thereby keeping the annular perspective plate 302 clean, allowing the operator to clearly observe the cutting of the laser cutting head 12 on the automobile parts through the observation window 305.

[0051] By rotating the knob 404 on the outer side of the fixed cylinder 403, the threaded rod 405 rotates, thereby adjusting the position of the limiting block 406 on the annular limiting frame 407. When the limiting block 406 moves towards the rubber wiping plate 402, the compression spring 408 is compressed. The elastic force generated by the compression of the compression spring 408 is transmitted to the rubber wiping plate 402 through the connecting block 409, causing the rubber wiping plate 402 to slide outward along the housing 401 and increase the pressure on the annular perspective plate 302, enhancing the wiping effect, which is suitable for the case where the surface of the annular perspective plate 302 is more dirty and stubborn.
