[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0018] See also Figure 1-Figure 8 A laser peeling mechanism for metal parts processing comprises a pipe 31, a laser cutting head 1 connected to a laser peeling machine, a clamping and rotating mechanism 2 connected to the laser peeling machine, a moving push block 3 connected to a frame of the laser peeling machine, a suction pipe 4 installed on the moving push block 3 and a slag extraction copper pipe 13 connected to the suction pipe 4, an inner wall of the slag extraction copper pipe 13 is connected with an arc scraper 14, the arc scraper 14 is slidably connected to the inner wall of the slag extraction copper pipe 13, a rotating shaft 10 is passed through the axis of the slag extraction copper pipe 13, one end of the rotating shaft 10 is fixedly connected with a connecting rib 23 in the slag extraction copper pipe 13, the other end of the connecting rib 23 is fixedly connected to the outer end of the arc scraper 14, a sealing ring is provided at the connection between the rotating shaft 10 and the slag extraction copper pipe 13, the suction pipe 4 is located below the rotating shaft 10, the suction pipe 4 is fixedly connected to the slag extraction copper pipe 13, the suction pipe 4 is communicated with the inside of the slag extraction copper pipe 13, and a linkage is connected to the outside of the suction pipe 4.

[0019] In the laser rotary cutting mechanism for metal parts processing of the present invention, after the tube 31 extends out from the clamping rotating mechanism 2, the movable push block 3 is pushed by the cylinder (shown in the figure but not numbered), so that the movable push block 3 moves, drives the extraction tube 4 to move, and when the extraction tube 4 moves, it drives the rotating shaft 10 to move at the same time, so that when the extraction tube 4 moves, it drives the slag extraction copper tube 13 to extend into the end of the tube 31. At this time, the laser cutting head 1 will cut the tube 31, so that the opening (shown in the figure but not numbered) on the slag extraction copper tube 13 receives the metal slag generated during cutting, and along with the negative pressure fan (known technology) connected to the tail end of the extraction tube 4 The slag extraction copper tube 13 is not shown in the figure. The slag extraction copper tube 13 is used to extract the molten metal slag. After the slag extraction copper tube 13 is splashed, part of it is sucked away with the negative pressure, and part of it is splashed, especially on the inner wall opposite to the opening of the slag extraction copper tube 13. At this time, under the action of the linkage, the shaft 10 is driven to rotate. The shaft 10 rotates while driving the connecting ribs 23, driving the arc scraper 14 to scrape the inner wall of the slag extraction copper tube 13, and the attached slag is quickly scraped off. After being scraped off, it will no longer adhere and will be sucked away by the negative pressure fan that continuously extracts air. This arrangement can avoid a large amount of slag adhering to the inner wall of the slag extraction copper tube 13 corresponding to the opening, which may cause blockage problems in the later stage.

[0020] By arranging an arc scraper 14 inside the slag extraction copper tube 13 and connecting it to the rotating shaft 10 by means of connecting ribs 23, the arc scraper 14 can be realized to perform circular rotation inside the slag extraction copper tube 13 as the extraction tube 4 moves, so that the arc scraper 14 can effectively scrape off the metal slag attached to the inner wall corresponding to the opening of the slag extraction copper tube 13, and the scraped metal slag can be smoothly sucked away by the continuous suction of its own negative pressure fan, and will not accumulate in the slag extraction copper tube 13; with the multiple scraping operations of the arc scraper 14, the thickness of the metal slag on the inner wall of the slag extraction copper tube 13 can be avoided, thereby effectively reducing the risk of pipeline blockage or poor suction due to slag accumulation.

[0021] As a preferred technical solution of the present invention, both end outer walls of the arc-shaped scraper 14 are chamfered.

[0022] Specifically, in order to make the scraping effect of the arc scraper 14 better, the outer walls at both ends of the arc scraper 14 are chamfered, so that the arc scraper 14 can scrape the metal slag better.

[0023] As a preferred technical solution of the present invention, the linkage part includes a fixed plate 7, which is fixedly installed on the frame of the laser peeling machine. The fixed plate 7 is located on the left side of the movable push block 3. The suction tube 4 passes through the fixed plate 7 and is slidably connected to it. A threaded sleeve 16 is fixedly connected inside the fixed plate 7. The top of the movable push block 3 is fixedly connected to a top block 11. The end of the rotating shaft 10 away from the slag extraction copper tube 13 is passed through a threaded sleeve 16 and is rotatably connected to the top block 11. An external thread is opened on the outside of the rotating shaft 10, and the external thread of the rotating shaft 10 is threadedly connected to the threaded sleeve 16.

[0024] Specifically, since the slag extraction copper tube 13 needs to move backward after completing the cutting of the tube 31 once, in order to facilitate the detachment of the tube 31, when the movable push block 3 moves, it drives the top block 11 to move synchronously, drives the extraction tube 4 and the rotating shaft 10 to move in the fixed plate 7 at the same time, and the extraction tube 4 slides in the fixed plate 7. The outer side of the rotating shaft 10 is provided with an external thread. Therefore, when the top block 11 pushes the rotating shaft 10 forward, the external thread on the outer side is connected with the internal thread of the threaded sleeve 16 in the fixed plate 7, so that the rotating shaft 10 rotates. While the tail end of the rotating shaft 10 and the top block 11 rotate, the top end also rotates on the axis of the slag extraction copper tube 13, driving the connecting rib 23 and the arc scraper 14 to rotate, and then completing the scraping of the inner wall of the slag extraction copper tube 13. By using this hard scraping method, the attached metal slag can be well scraped up and sucked away by its own negative pressure fan; Since the suction tube 4 reciprocates, the rotation of the rotating shaft 10 is also reciprocating. Therefore, the rotating shaft 10 will rotate repeatedly under the action of the threaded sleeve 16, thereby causing the arc-shaped scraper 14 to rotate repeatedly, so that the slag can be scraped off by repeated rotation.

[0025] By cooperating with the fixed plate 7, the threaded sleeve 16, the top block 11 and the rotating shaft 10, when the movable push block 3 moves back and forth, the rotating shaft 10 can be rotated to realize the arc scraper 14 to scrape the slag. By using this hard scraping method, the attached metal slag can be scraped up well. Since the suction tube 4 is a reciprocating motion, the rotation of the rotating shaft 10 is also a reciprocating motion. Therefore, the rotating shaft 10 will rotate repeatedly under the action of the threaded sleeve 16, thereby making the arc scraper 14 rotate repeatedly, and the slag can be scraped up by repeated rotation.

[0026] As a preferred technical solution of the present invention, an arc groove 17 is provided on the inner wall of the slag extraction copper tube 13 , and an arc block 29 fixedly connected to the back of the arc scraper 14 is slidably connected in the arc groove 17 .

[0027] Specifically, when the arc scraper 14 rotates, the arc block 29 on the back side thereof will slide with the arc groove 17. This arrangement can make the arc scraper 14 more stable when rotating.

[0028] As a preferred technical solution of the present invention, the outer end of the slag extraction copper tube 13 is connected to a grinding steel brush 15, the axial shaft of the grinding steel brush 15 is fixedly connected to a grinding shaft 19, the outer side of the clamping and rotating mechanism 2 is connected to a mounting plate 5, the mounting plate 5 is fixedly connected to the frame of the laser peeling machine through a bracket 12, and a mounting ring groove 24, a material discharge groove 25 and a side groove 26 are provided in the mounting plate 5, the mounting ring groove 24, the material discharge groove 25 and the side groove 26 are interconnected, and a rotating plate 9 is rotatably connected in the mounting ring groove 24, and the pipe 31 is clamped and rotated. The rotating mechanism 2 is penetrated by a rotating plate 9, and a plurality of teeth 28 are fixedly connected to the outer wall of the rotating plate 9, a gear 27 is rotatably connected in the side groove 26, a fixed shaft of the gear 27 is rotatably connected to the mounting plate 5, a motor 8 is fixedly installed on the outer wall of the mounting plate 5, an output end of the motor 8 is fixedly connected to the fixed shaft of the gear 27, the gear 27 is meshingly connected to the teeth 28 of the rotating plate 9, pneumatic V-shaped clamping rollers 6 for clamping pipes 31 are installed on both sides of the outer wall of the rotating plate 9, and a vertical opening 30 connected to the unloading chute 25 is opened at the lower part of the rotating plate 9.

[0029] Specifically, the metal slag generated when the pipe 31 is cut has been largely extracted by the slag extraction copper tube 13, but a small amount of metal slag will still splash onto the inner wall of the pipe 31 to form slag, which can be polished using the polishing steel brush 15 at the end of the slag extraction copper tube 13. The specific operation is as follows: After the tube 31 extends out from the clamping rotating mechanism 2, it will enter the rotating plate 9 in the mounting plate 5. At this time, the laser cutting head 1 starts cutting. After the cutting is completed, the tube 31 will just fall on the slag extraction copper tube 13. At this time, the tube 31 is still located in the rotating plate 9, and the pneumatic V-shaped clamping roller 6 clamps the tube 31. After clamping, the motor 8 is started to drive the output end of the motor 8 to work, drive the gear 27 to rotate, and make the gear 27 mesh with the teeth 28 on the outer side of the rotating plate 9, drive the rotating plate 9 to rotate in the fixed plate 7. Since the tube 31 has been cut off, the tube 31 is driven by the rotating plate 9 to rotate in the process of the slag extraction copper tube 13 retreating backward, so that the inner wall of the tube 31 is polished by the polishing steel brush 15, so as to ensure that there is no slag on the inner wall of the product after cutting, and avoid secondary processing; After the tube 31 is polished, the slag extraction copper tube 13 is completely withdrawn from the tube 31 , the pneumatic V-shaped clamping roller 6 releases the clamping, and the tube 31 is discharged through the discharge chute 25 .

[0030] As a preferred technical solution of the present invention, an outer plate 18 is fixedly connected to the outer side of one end of the slag extraction copper tube 13 away from the extraction tube 4, a movable groove 20 is opened in the outer plate 18, a movable block 21 is slidably connected in the movable groove 20, and two springs 22 are fixedly connected to the bottom surface of the movable block 21, and the bottom surfaces of the two springs 22 are against the movable groove 20.

[0031] Specifically, since the diameter of the slag extraction copper tube 13 is usually smaller than the diameter of the pipe 31, the slag extraction copper tube 13 is not coaxial when entering the pipe 31. In order for the grinding steel brush 15 to smoothly grind the inner wall of the pipe 31, a diameter corresponding to the pipe 31 is set. When the slag extraction copper tube 13 enters the pipe 31, the grinding steel brush 15 squeezes the pipe 31. The steel bristles of the steel brush here can be made of high carbon steel and other materials with a certain hardness. When the grinding steel brush 15 squeezes the pipe 31, The grinding shaft 19, under the action of the moving block 21 and the spring 22, will force the spring 22 to be compressed, and the moving block 21 will descend in the moving groove 20, so that the grinding steel brush 15 can coaxially enter the pipe 31. After the pipe 31 is cut and clamped by the pneumatic V-shaped clamping roller 6, the grinding steel brush 15, under the action of the moving block 21 and the spring 22, can always be coaxial with the pipe 31. When the pipe 31 rotates, the grinding steel brush 15 does not move, so that the slag on the inner wall of the pipe 31 can be polished and cleaned.

[0032] As a preferred technical solution of the present invention, a ring plate 32 is fixedly connected to the outer end of the moving block 21 , and the ring plate 32 is connected to the grinding shaft 19 of the grinding steel brush 15 via a fastening bolt 33 .

[0033] Specifically, since the pipes 31 have different lengths and diameters, the grinding shaft 19 can be disassembled and fixed by fastening bolts 33 and the ring plate 32. In this way, the steel brush with the corresponding length and diameter of the pipe 31 can be replaced.

[0034] As a preferred technical solution of the present invention, the cross-sections of the moving groove 20 and the moving block 21 are arranged in a T-shape. This arrangement can facilitate the moving block 21 to move more stably in the moving groove 20.

[0035] In the above structure, the cylinder negative pressure fan and the motor 8 are both known technologies, so they are not described in detail here.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
