Description

Technical Field

[0001] This invention relates to the field of laser cutting processing, specifically to a laser cutting device for metal parts used in aircraft blade processing. Background Technology

[0002] Aircraft blades are core rotating components of aircraft propulsion and auxiliary systems. Their main function is to accelerate, compress, or perform work on air through high-speed rotation, thereby generating thrust or driving other mechanical components. The blade body is made of special metal materials through precision machining. During the machining process, large metal sheets are cut using laser cutting equipment, and a high-power laser cutting machine is used to cut them into blanks that approximate the shape of blades, providing a foundation for subsequent processes.

[0003] In laser cutting of metal raw materials, the raw material is typically placed on a scimitar rack to avoid obstructing the laser beam path. To prevent slag buildup in the gaps between the scimitar racks, existing laser cutting devices often have two symmetrically inclined base plates at the bottom of the racks to guide the slag towards a spiral conveyor blade for slag removal. However, in the initial stages of laser cutting, the slag is often in a molten or semi-molten state, making it highly susceptible to adhering to the inclined base plate surface. This leads to continuous slag accumulation, not only hindering proper slag removal but also increasing the difficulty of subsequent slag cleaning. Summary of the Invention

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

It includes a device housing 1 and two first electric slides 2 symmetrically fixedly installed on the top of the device housing 1. A support base 3 is installed on the top of the first electric slides 2, and a second electric slide 4 is fixedly installed between the two support bases 3. A laser cutter 5 is installed on the outside of the second electric slide 4. A mounting frame 6 is fixedly installed on the inside of the device housing 1, and multiple equally spaced sword racks 7 are fixedly installed on the inside of the mounting frame 6. When the metal part is placed on the multiple sword racks 7, the first electric slide 2 is activated to adjust the position of the support base 3, so that the two support bases 3 adjust the longitudinal position of the second electric slide 4. The second electric slide 4 can adjust the lateral position of the laser cutter 5, which facilitates the laser cutter 5 to perform laser cutting processing on the metal part. The scraping mechanism includes a scraper 8 disposed inside the device housing 1, which can concentrate and clean welding slag. The scraping mechanism also includes two symmetrically fixed sliding frames 11 fixedly installed inside the device housing 1. An electric screw 12 is installed inside the sliding frame 11, and a slider 13 is disposed inside the sliding frame 11. The slider 13 is threaded onto the outside of the electric screw 12, and an optical shaft for limiting the sliding of the slider 13 is fixedly installed inside the sliding frame 11. When the electric screw 12 rotates, it can drive the slider 13 to move along the outside of the optical shaft. A mounting plate 14 is fixedly installed between the two sliders 13. A plurality of telescopic rods 15 are fixedly installed between the mounting plate 14 and the scraper 8. A tension spring 16 is sleeved on the outside of the telescopic rod 15, and the tension spring 16 is fixedly installed between the mounting plate 14 and the scraper 8. Between plates 8, two symmetrically distributed sleeves 17 are fixedly installed on the top of mounting plate 14. A sliding rod 18 is slidably installed on the inner side of the sleeve 17, and one end of the sliding rod 18 extends to the outer side of the sleeve 17 and has a hemispherical structure. Two symmetrically distributed fixing plates 19 are fixedly installed on the inner side of the device housing 1. The outer side of the fixing plate 19 is provided with a first sliding groove and a second sliding groove for limiting the sliding of the sliding rod 18. The first sliding groove is located below the second sliding groove, and the two ends of the first sliding groove and the second sliding groove are respectively connected by an inclined groove and a straight groove. The inclined groove is located at the left end of the first sliding groove and the straight groove is located at the right end of the first sliding groove and the second sliding groove. A triangular inclined plate 20 is fixedly installed at the right end of the first sliding groove and the left end of the second sliding groove. The triangular inclined plate 20 located at the left end of the second sliding groove is close to One side of the chute is an inclined surface. A spring 21 is fixedly installed between the end of the slide rod 18 away from the fixed plate 19 and the inner side of the sleeve 17. A guide plate 22 is fixedly installed on the inner side of the device housing 1. The welding slag produced when the laser cutter 5 cuts the metal parts can fall onto the guide plate 22, and the inclination angle of the guide plate 22 is the same as the inclination angle of the first chute. The top of the guide plate 22 is in contact with the bottom of the scraper 8. The two sliders 13 can drive the mounting plate 14 to move synchronously, so that the mounting plate 14 drives the scraper 8 and the two sleeves 17 to move synchronously through the telescopic rod 15. The sleeves 17 drive the slide rod 18 to move along the inner side of the first chute, and the scraper 8 can move along the top of the guide plate 22, so that the scraper 8 can scrape off the welding slag on the surface of the guide plate 22 in time. When the slide rod 18 contacts the triangular inclined plate 20 at the right end of the first chute, the spherical end of the slide rod 18 can move along the inclined surface of the triangular inclined plate 20 and compress the spring 21, causing the slide rod 18 to enter the straight chute. The rebound force of the tension spring 16 pulls the scraper 8 away from the guide inclined plate 22, causing the slide rod 18 to enter the second chute along the straight chute. The electric screw 12 drives the mounting plate 14 to reset via the slider 13, causing the mounting plate 14 to pull the scraper 8 to reset via the telescopic rod 15. The slide rod 18 can then move along the inner side of the second chute. When the slide rod 18 contacts the triangular inclined plate 20 in the second chute, the elasticity of the spring 21 causes the slide rod 18 to enter the inclined chute. The slide rod 18 can also return to the first chute along the inclined surface of the inclined chute and the triangular inclined plate 20.The scraper 8 cleans the welding slag on the surface of the guide plate 22 in one direction, facilitating the concentrated pushing of the welding slag to the right side of the guide plate 22. Multiple equally spaced support bars 37 are fixedly installed on the inner side of the device housing 1. The number of support bars 37 is the same as the number of sword-grid racks 7, and the support bars 37 are located directly below the sword-grid racks 7, providing shielding for the support bars 37. The mounting plate 14 is slidably installed on the outer side of the support bars 37, and can move along the top of the multiple support bars 37, improving the stability of the mounting plate 14's movement. A support rod 38 is fixedly installed on the inner side of the sleeve 17, and an insertion hole is provided on the outer side of the slide rod 18 for the support rod 38 to be inserted, providing support for the slide rod 18 and preventing the slide rod 18 from tilting.

[0022] Example 2: Please refer to Figures 2-8This embodiment further illustrates Example 1. The slag removal mechanism shown in the figure includes a slag removal cylinder 9 fixedly installed inside the outer casing 1 of the device. The slag removal cylinder 9 can scrape up the welding slag by the scraper 8. The slag removal mechanism also includes a rotating rod 23 rotatably installed inside the slag removal cylinder 9. A spiral scraper 24 is fixedly installed on the outer side of the rotating rod 23, and the outer side of the spiral scraper 24 is in contact with the inner side of the slag removal cylinder 9. A drive motor 25 is fixedly installed at one end of the slag removal cylinder 9, and the output end of the drive motor 25 is fixedly connected to one end of the rotating rod 23. The outer side of the slag removal cylinder 9 is fixedly connected to the right end of the guide plate 22. The top of the slag discharge cylinder 9 has a feed inlet. A slag discharge pipe 26 is fixedly installed at the end of the slag discharge cylinder 9 furthest from the drive motor 25. The scraper 8 pushes the welding slag from the top of the guide plate 22 into the slag discharge cylinder 9 through the feed inlet. The drive motor 25 drives the rotating rod 23 to rotate, which in turn drives the spiral scraper 24 to rotate. The spiral scraper 24 pushes the welding slag inside the slag discharge cylinder 9, causing it to be discharged outwards through the slag discharge pipe 26, facilitating timely recovery of the welding slag. A driven rod 27 is rotatably installed inside the outer casing 1, and the driven rod 27 is located above the feed inlet of the slag discharge cylinder 9. Multiple elastic scrapers 28 are fixedly installed on the outer side of the moving rod 27, arranged in a centrally symmetrical manner. The scraper 8 has an arc-shaped concave surface structure on the side near the elastic scrapers 28, extending from one end of the moving rod 27 to the outer side of the device housing 1. A synchronous belt 29 is rotatably installed between the driven rod 27 and the rotating rod 23. During the movement of the scraper 8, the welding slag can be concentrated in the arc-shaped concave surface of the scraper 8. When the sliding rod 18 enters the straight groove of the fixed plate 19, the arc-shaped concave surface of the scraper 8 can contact the elastic scrapers 28. The rotating rod 23 can drive the driven rod 27 to rotate through the synchronous belt 29, causing the driven rod 27 to drive... Multiple elastic scrapers 28 perform circular motion, scraping away the welding slag in the arc-shaped concave surface of the scraper 8 and feeding it into the slag discharge cylinder 9. A positioning plate 39 is fixedly installed at the end of the slag discharge cylinder 9 away from the drive motor 25. One end of the driven rod 27 and the rotating rod 23 are rotatably installed on the outside of the positioning plate 39, so that the positioning plate 39 provides support for the driven rod 27 and the rotating rod 23, ensuring that the rotating rod 23 smoothly transmits power to the driven rod 27. An arc-shaped groove is opened on the inner side of the device housing 1 to allow the elastic scraper 28 to perform circular motion, so that the elastic scraper 28 can perform circular motion along the inner side of the arc-shaped groove, preventing welding slag from leaking out.

[0023] Example 3: Please refer to Figures 2-6 and Figure 9This embodiment further illustrates other embodiments. The scraping mechanism shown in the figure includes two symmetrical metal brushes 10 located on both sides of the sword rack 7. The two metal brushes 10 can perform rolling cleaning on the sword rack 7. The scraping mechanism also includes a mounting box 30 disposed below the sword rack 7. The mounting box 30 is fixedly mounted on the top of the mounting plate 14. Two symmetrically distributed first mounting rods 31 are rotatably mounted inside the mounting box 30. Both first mounting rods 31 extend above the mounting box 30, and the two metal brushes 10 are fixedly mounted on the outer sides of the two first mounting rods 31. The inner side of the mounting box 30 is rotatably mounted on... A second mounting rod 32 is provided. Drive wheels 33 are fixedly mounted on the outer sides of both the first mounting rod 31 and the second mounting rod 32. The three drive wheels 33 are connected via a drive belt 34, which is a sprocket and a chain, respectively. A rack plate 35 is fixedly mounted on the bottom of the sword rack 7. The width of the rack plate 35 is smaller than the width of the sword rack 7, allowing the sword rack 7 to provide cover for the rack plate 35. A groove corresponding to the rack plate 35 is formed on the top of the mounting box 30. A gear 36 that meshes with the rack plate 35 is fixedly mounted on the top of the second mounting rod 32. The top of the mounting box 30 contacts the bottom of the sword rack 7, allowing... Mounting box 30 works with rack 7 to protect rack plate 35, preventing debris and residue from getting stuck between rack plate 35 and gear 36. When mounting plate 14 moves, it drives mounting box 30 to move synchronously, causing mounting box 30 to drive first mounting rod 31 and second mounting rod 32 to move synchronously. Second mounting rod 32 drives gear 36 to move along the outer side of rack plate 35, causing rack plate 35 to drive second mounting rod 32 to rotate via gear 36. Second mounting rod 32 drives transmission belt 34 to rotate via transmission wheel 33, and works with two other transmission wheels 33 to drive two first mounting rods 31 to rotate synchronously. Two metal brushes 10 are rotated, causing them to move along the outer side of the sword rack 7 in a rotating state, which facilitates the cleaning of small pieces of welding slag on the outer side of the sword rack 7. Two symmetrically distributed U-shaped frames 40 are fixedly installed on the top of the mounting box 30. Two first mounting rods 31 are rotatably installed on the inner side of the two U-shaped frames 40. The U-shaped frames 40 can provide auxiliary support for the first mounting rods 31 to prevent them from tilting. A stop bar 41 is fixedly installed on the inner side of the U-shaped frame 40. When the metal brushes 10 rotate, they can rotate along the outer side of the stop bar 41, which facilitates the cleaning of welding slag remaining inside the metal brushes 10.

[0024] Working principle: First, the operator places the metal part to be processed on the multiple toothed racks 7 on the top of the mounting frame 6. The first electric slide 2 and the second electric slide 4 are then activated. The two first electric slides 2 drive the two support seats 3 to move, allowing the support seats 3 to adjust the longitudinal position of the second electric slide 4. The second electric slide 4 then drives the laser cutter 5 to move laterally, moving the laser cutter 5 to the initial cutting point of the metal part. The laser cutter 5 is then activated, working in conjunction with the first and second electric slides 2 and 4 to cut the metal part. At this time, the welding slag produced by the laser cutter 5 during cutting falls onto the guide plate 22. The operator then activates the two electric screws 12, which rotate clockwise, causing the electric screws to rotate clockwise. The moving screw 12 drives the slider 13 to move along the outer side of the optical axis. The two sliders 13 drive the mounting plate 14 to move. The mounting plate 14 drives the scraper 8 and the two sleeves 17 to move synchronously through multiple telescopic rods 15. The sleeves 17 drive the sliding rod 18 to move along the inner side of the first chute, so that the scraper 8 moves along the top of the guide plate 22 towards the slag discharge cylinder 9. The scraper 8 scrapes up the welding slag on the surface of the guide plate 22 and temporarily stores it on the arc-shaped concave surface on the outer side of the scraper 8, pushing the welding slag towards the slag discharge cylinder 9. When the sliding rod 18 contacts the triangular inclined plate 20 at the right end of the first chute, the spherical end of the sliding rod 18 can move along the inclined surface of the triangular inclined plate 20 and compress the spring 21. When the sliding rod 18 moves away from the triangular inclined plate 20, the rebound force of the spring 21 is used to make the sliding rod 18 move away from the triangular inclined plate 20. 8. As the scraper plate enters the straight groove, the concave surface of the scraper plate 8 contacts the elastic scraper blade 28. The drive motor 25 drives the rotating rod 23 to rotate, and the rotating rod 23 drives the driven rod 27 to rotate via the synchronous belt 29. This causes the driven rod 27 to drive multiple elastic scraper blades 28 to perform circular motion. The elastic scraper blades 28 can scrape off the welding slag in the concave surface of the scraper plate 8 and send the welding slag into the slag discharge cylinder 9. Subsequently, the rebound force of the tension spring 16 pulls the scraper plate 8 away from the guide plate 22, so that the scraper plate 8 drives the sliding rod 18 along the straight groove into the second sliding groove via the sleeve 17. The electric screw 12 rotates in the opposite direction, so that the slider 13 drives the mounting plate 14 to reset. The mounting plate 14 pulls the scraper plate 8 to reset via the telescopic rod 15. The scraper plate 8 can then drive the sliding rod 18 to move along the inner side of the second sliding groove and... When the sliding rod 18 contacts the triangular inclined plate 20 in the second sliding groove, the elasticity of the spring 21 causes the sliding rod 18 to enter the inclined groove. The electric screw 12 then rotates in the forward direction, causing the sliding rod 18 to return to the first sliding groove along the inclined groove. This causes the scraper 8 to scrape up the welding slag on the surface of the guide inclined plate 22, facilitating the concentrated pushing of the welding slag to the right side of the guide inclined plate 22. At the same time, the rotating rod 23 drives the spiral scraper 24 to rotate along the inner side of the slag discharge cylinder 9, pushing the welding slag in the slag discharge cylinder 9 into the slag discharge pipe 26, facilitating timely and concentrated recovery of the welding slag. Furthermore, during the movement of the mounting plate 14, the mounting plate 14 can also drive multiple mounting boxes 30 located below the sword grid rack 7 to move synchronously, causing the mounting boxes 30 to drive the first mounting rod 31 and the second mounting rod 32 to move synchronously.The second mounting rod 32 drives the gear 36 to move along the outer side of the rack plate 35, causing the rack plate 35 to rotate via the gear 36. The second mounting rod 32 then drives the transmission belt 34 to rotate via the transmission wheel 33, which in turn drives the two first mounting rods 31 to rotate synchronously. The two first mounting rods 31 then drive the two metal brushes 10 to rotate, causing the metal brushes 10 to move along the outer side of the sword-grid rack 7 in a rotating state, cleaning the small pieces of welding slag adhering to the surface of the sword-grid rack 7. This achieves the effect of timely cleaning of welding slag and prevents its accumulation.
