Description

Technical Field

[0001] This invention belongs to the field of machining technology and relates to an adjustable cutting device and method for mechanical parts. Background Technology

[0002] The machining of mechanical parts is a crucial part of modern manufacturing, involving various processing methods, processes, and equipment. It is a complex and delicate production process that requires selecting appropriate processing techniques and equipment based on the shape, size, material, and precision requirements of the parts to ensure both quality and efficiency.

[0003] Laser cutting of sheet metal is extremely important in modern manufacturing, especially in sheet metal processing where high precision, high speed, and flexibility are required. During laser cutting of sheet metal, the laser melts the metal at the cutting location, producing slag. This slag adheres to the cutting bed, creating irregular protrusions that prevent the sheet metal from being placed horizontally. This significantly affects the flatness of the sheet metal and consequently, the actual cutting accuracy.

[0004] Patent document CN118321749A discloses a laser cutting device and method for sheet metal, including a cutting bed and a laser. The cutting bed is provided with several support members, including a first support member and a second support member. The first support member includes a first rotating shaft with a support part and a brush cleaning part. The second support member includes a second rotating shaft with a sliding sleeve slidably connected to it. The sliding sleeve has a support part and a brush cleaning part. The second rotating shaft is provided with a reciprocating drive member for driving the sliding sleeve to move back and forth. Both the first and second rotating shafts are rotatably connected to the cutting bed. The first and second rotating shafts are driven to rotate synchronously by a rotary drive mechanism. A second support member is provided between two adjacent first support members.

[0005] The aforementioned device causes relative movement between the support portion on two adjacent support members and the brushing cleaning component. The brushing cleaning component brushes the surface of the support portion to remove the molten slag adhering to the surface. However, the molten slag solidifies and adheres to the support member after cooling, making it difficult for the brushing cleaning component to scrape off the solidified slag, resulting in poor cleaning effect and consequently affecting cutting accuracy.

[0006] To address the above problems, this invention proposes an adjustable cutting device and method for mechanical parts. Summary of the Invention

[0007] To address the problems existing in the background art, the present invention proposes an adjustable cutting device and method for mechanical parts.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: an adjustable cutting device for mechanical parts, comprising a cutting bed, a cutting mechanism disposed above the cutting bed, a connecting block, and a support member; the connecting block is rotatably installed inside the cutting bed, the connecting block has a receiving cavity, the connecting block has a sliding groove communicating with the receiving cavity, the support member is movably disposed within the sliding groove, and an extrusion block is elastically movably disposed on the connecting block, one end of the extrusion block slidingly engages with one side of the support member, the support member is provided with a limiting component that keeps the extrusion block in contact with the support member, the extrusion block slides along one side of the support member, thereby causing the support member to move into the receiving cavity; a slag removal liquid is disposed between the bottom surface of the connecting block and the bottom wall of the cutting bed.

[0009] The extrusion block pushes the support component into the connecting block. The extrusion block and connecting block scrape and clean the slag on the support component. When the slag solidifies and firmly adheres to the support component, making it difficult for the extrusion block and connecting block to remove the slag, the limiting component keeps the extrusion block and support component in close contact, preventing the extrusion block from crossing the slag. Consequently, the slag prevents the extrusion block from continuing to move along the support component, and the support component cannot move further into the connecting block. Due to the slag's obstruction, part of the support component is located outside the connecting block. Thus, when the connecting block flips, the portion of the support component outside the connecting block is immersed in the slag removal solution, preventing excessive contact between the support component and the solution, reducing its impact. When the slag separates from the support component or the connection loosens, the extrusion block pushes the support component into the connecting block, preventing prolonged immersion in the solution and extending its service life. Meanwhile, the extrusion block and the connecting block scrape off the slag removal liquid on the support, preventing the slag removal liquid from entering the connecting block.

[0010] Furthermore, the support member is triangular in shape, and its vertices are rounded. This prevents scratches on the sheet material when it is placed on the support member.

[0011] Furthermore, the end of the extrusion block near the support member has an arc surface adapted to the rounded corner. This forms a cutting edge at the end of the extrusion block near the support member, allowing for better scraping of molten slag from the support member as the extrusion block moves along it, resulting in a better cleaning effect.

[0012] Furthermore, the limiting component includes a guide rod and a vertical rod. The guide rod is fixedly connected to the support member, and a guide groove is formed on the guide rod, extending onto the support member. The length direction of the guide groove is parallel to the corresponding side of the support member. One end of the vertical rod is fixedly connected to the extrusion block, and the other end of the vertical rod is slidably positioned within the guide groove. When the extrusion block moves along the support member, the vertical rod moves along the guide groove, thereby keeping the extrusion block in close contact with the support member. This prevents the extrusion block from crossing the molten slag, and thus, due to the obstruction of the molten slag, the support member cannot continue to move into the connecting block, ensuring that both the support member and the molten slag adhered to the support member are located outside the connecting block.

[0013] Furthermore, the connecting block has sliding grooves on both its upper and lower sides that communicate with the receiving cavity, and each sliding groove contains a support member. When the slag on the lower support member of the connecting block is immersed in the casting removal liquid, the upper support member of the connecting block can support the plate for processing, which helps to improve the working efficiency of the device.

[0014] Furthermore, a second electric push rod is fixedly installed inside the connecting block. The telescopic end of the second electric push rod extends into the storage cavity. A connecting rod is fixedly connected to the telescopic end of the second electric push rod. A clearance groove is provided on the bottom edge of the support member. A sliding rod is slidably arranged in the clearance groove and is fixedly connected to the connecting rod.

[0015] Furthermore, a rack is movably provided on one side of the cutting bed, and a gear is fixedly connected to the end of the connecting block, with the gear meshing with the rack.

[0016] Furthermore, the cutting bed is fixedly equipped with a first electric push rod, and a first slider is fixedly connected to the telescopic end of the first electric push rod. The first slider is fixedly connected to the rack.

[0017] Furthermore, the cutting mechanism includes a laser cutting head, a first electric slide rail is mounted on the cutting bed, an electrically controlled telescopic rod is mounted on a first electric slider matched with the first electric slide rail, a second electric slide rail is mounted on the telescopic end of the electrically controlled telescopic rod, a second electric slider is matched with the second electric slide rail, and the laser cutting head is mounted on the second electric slider.

[0018] The specific steps of the cutting method for mechanical parts in this invention are as follows: S1. The sheet material is placed on multiple support components, and the cutting mechanism cuts the sheet material. S2. After cutting, remove the plate from the cutting bed and rotate the connecting block 90 degrees. S3. Then the extrusion block pushes the support component into the connecting block, and the extrusion block and the connecting block clean the slag on the support component; S4. When the extrusion block and the connecting block cannot remove the slag on the support, part of the support is located outside the connecting block due to the obstruction of the slag. S5. Continue to rotate the connecting block, thereby immersing the part of the support outside the connecting block in the slag removal liquid inside the cutting bed; S6. After the slag separates from the support, the support continues to move into the connecting block under the push of the extrusion block; the extrusion block and the connecting block scrape off the slag removal liquid on the support.

[0019] Compared with the prior art, the present invention has the following beneficial effects: 1. When the sliding rod moves out of the limiting groove of the support, the extrusion block pushes the support into the connecting block under the action of the spring. The extrusion block and the connecting block scrape and clean the slag on the support to ensure processing accuracy.

[0020] 2. When the extrusion block and connecting block cannot remove the slag from the support, the support cannot continue to move into the connecting block due to the obstruction of the slag. This causes part of the support to be located outside the connecting block, causing the connecting block to flip over. Consequently, the part of the support located outside the connecting block is immersed in the slag removal liquid, while the support without the obstruction of slag will completely enter the connecting block without contacting the slag removal liquid, thus reducing the unnecessary impact of the slag removal liquid on the support.

[0021] 3. After the slag separates from the support component, the extrusion block continues to push the support component into the connecting block, preventing the support component from being immersed in the slag removal liquid for a long time, which would affect its service life. At the same time, the slag removal liquid on the support component is cleaned by the extrusion block and the connecting block, preventing the slag removal liquid from entering the connecting block.

[0022] 4. When the second electric push rod is started, when the first support moves into the connecting block, the second support moves to the outside of the connecting block. Then, when the first support is immersed in the slag removal liquid, the second support is above the connecting block and can support the plate. Thus, the workpiece can still be processed while being immersed in the slag, which helps to improve the production efficiency of the device while ensuring processing accuracy.

[0025] 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.

[0026] like Figures 1-15As shown, the technical solution adopted by the present invention is as follows: an adjustable cutting device for mechanical parts includes a cutting bed 1, a cutting mechanism, a connecting block 9, and a support member 8.

[0027] The cutting mechanism includes a laser cutting head 7. The laser cutting head 7 is movably positioned above the cutting bed 1. First electric slide rails 4 are installed on both sides of the cutting bed 1. Electrically controlled telescopic rods 5 are fixedly connected to the first electric sliders 16 of the first electric slide rails 4. A second electric slide rail 6 is fixedly connected between the telescopic ends of the two electrically controlled telescopic rods 5. A second electric slider 17 is installed on the second electric slide rail 6, and the laser cutting head 7 is mounted on the second electric slider 17. The position of the laser cutting head 7 is adjusted by the first electric slider 16, the electrically controlled telescopic rods 5, and the second electric slider 17. The laser cutting head 7 cuts the sheet metal on the cutting bed 1.

[0028] Multiple connecting blocks 9 are rotatably mounted inside the cutting bed 1, and the connecting blocks 9 are parallel to each other. A shaft 15 is fixedly mounted at the end of each connecting block 9. The shaft 15 is rotatably connected to the cutting bed 1. One of the shafts 15 extends outside the cutting bed 1 and is fixedly connected to a gear 10. A rack 11 is slidably connected to the cutting bed 1, and the rack 11 meshes with the gear 10. A first electric push rod 14 is fixedly connected to the cutting bed 1, and a first slider 12 is fixedly connected to the telescopic end of the first electric push rod 14. A first sliding groove 13 is formed on the cutting bed 1, and the first slider 12 is slidably positioned within the first sliding groove 13. The first slider 12 is fixedly connected to the gear 10. The telescopic movement of the first electric push rod 14 drives the first slider 12 to move, which in turn causes the rack 11 to move. The movement of the rack 11 drives the gear 10 to rotate, which in turn causes the connecting blocks 9 to rotate.

[0029] The connecting block 9 has a storage cavity. Sliding grooves are formed on both the top and bottom sides of the connecting block 9, and a support member 8 is slidably mounted in each groove. The upper part of the support member 8 is triangular. The apex of the support member 8 is positioned away from the connecting block 9, and the apex of the support member 8 has rounded corners. This prevents the board from being scratched when placed on the support member 8.

[0030] Both sides of the support member 8 are in sliding contact with the inner wall of the sliding groove. A clearance groove 27 is formed on the bottom edge of the support member 8 within the connecting block 9. A sliding rod 19 is slidably disposed within the clearance groove 27. A second electric push rod 28 is fixedly installed within the connecting block 9, and a connecting rod 20 is fixedly connected to the telescopic end of the second electric push rod 28. The sliding rod 19 is fixedly connected to the connecting rod 20. The connecting rod 20 is located within the clearance cavity.

[0031] Each support member 8 has a pressing block 18 fitted on both sides. One end of the pressing block 18 slides in contact with the side of the support member 8, and the other end of the pressing block 18 is fixedly connected to a third slider 22. A third groove 21 is provided on the connecting block 9, which slides in cooperation with the third slider 22, and the third slider 22 is slidably disposed in the third groove 21. A spring groove is provided on the connecting block 9, which communicates with the third groove 21. A spring 23 is provided in the spring groove, one end of the spring 23 is fixedly connected to the end of the third slider 22 away from the pressing block 18, and the other end of the spring 23 is fixedly connected to the end wall of the spring groove.

[0032] The second electric push rod 28 is activated, causing the sliding rod 19 to move out of the relief groove 27 of the support member 8. Under the action of the spring 23, the third slider 22 moves closer to the support member 8, and the pressing block 18 presses the support member 8, causing the support member 8 to move into the connecting block 9. The pressing block 18 moves along the side of the support member 8 towards the apex of the support member 8.

[0033] The extrusion block 18 has an arc-shaped surface 29 at one end near the support member 8, forming a cutting edge at that end. As the extrusion block 18 moves along the support member 8, the cutting edge cleans the support member 8, effectively scraping away slag from its sides. The arc-shaped surface 29 is fitted to the apex of the support member 8. This allows the extrusion block 18 to move along the apex of the support member 8 when it reaches it, and the cutting edge of the extrusion block 18 can remove the slag at the apex of the support member 8.

[0034] A limiting assembly is provided on the support member 8 to keep the extrusion block 18 in close contact with the side of the support member 8. The limiting assembly includes a guide rod 25 and a vertical rod 24. The guide rod 25 is fixedly connected to the support member 8. A guide groove 26 is formed on the guide rod 25, extending onto the support member 8. One end of the guide groove 26 on the support member 8 is provided with an arc-shaped groove. The length direction of the guide groove 26 is parallel to the corresponding side of the support member 8. One end of the vertical rod 24 is fixedly connected to the extrusion block 18, and the other end of the vertical rod 24 is fixedly connected to a guide block, which is slidably positioned within the guide groove 26. When the extrusion block 18 slides along the side of the support member 8, the guide block slides along the guide rod 25. The arc-shaped groove is fitted with the rounded corner at the apex of the support member 8. When the sliding rod 19 engages with the apex of the support member 8, the guide block is located within the arc-shaped groove.

[0035] When the extrusion block 18 presses against the support member 8, causing the support member 8 to move into the connecting block 9, the cutting edge of the extrusion block 18 cleans the side of the support member 8, and the connecting block 9 cleans the side of the support member 8. If solidified slag adheres to the side of the support member 8, and the cutting edge of the extrusion block 18 cannot scrape off the solidified slag, the extrusion block 18 remains tightly pressed against the side of the support member 8 due to the limiting component, making it difficult for the extrusion block 18 to overcome the slag adhered to the support member 8. Consequently, the support member 8 cannot continue to move into the receiving cavity. The apex of the support member 8 extends beyond the connecting block 9.

[0036] As the support member 8 moves into the connecting block 9, the connecting block 9 scrapes and cleans the slag on the side of the support member 8. If the connecting block 9 cannot remove the solidified slag adhering to the side of the support member 8, the support member 8 cannot continue to move into the connecting block 9, and the apex of the support member 8 is located outside the connecting block 9.

[0037] If there is no molten slag blocking the two sides and the two sides of the support member 8, the support member 8 will enter the connecting block 9 under the push of the extrusion block 18, and the two extrusion blocks 18 corresponding to the support member 8 will contact the ends of the support member 8 and block the top of the support member 8.

[0038] When the connecting rod 20 drives the sliding rod 19 to move into the relief groove 27 of the support member 8, the sliding rod 19 pushes the support member 8 to move outward from the connecting block 9. The connecting block 9 pushes the pressing block 18 to move, causing the third slider 22 to slide in the third slide groove 21, and the spring 23 is compressed. At the same time, the guide block at one end of the vertical rod 24 slides along the guide groove 26 towards the end away from the support member 8.

[0039] The cutting bed 1 is equipped with an inlet pipe 2 and an outlet pipe 3. The slag removal liquid is injected into the cutting bed 1 through the inlet pipe 2. Initially, the support member 8 on the upper side of the connecting block 9 extends outside the connecting block 9, while the support member 8 on the lower side of the connecting block 9 is located inside the connecting block 9. For example... Figure 15 As shown, the height of the slag removal fluid inside the cutting bed 1 is H, so the distance between the lower end face of the connecting block 9 and the bottom wall of the cutting bed 1 is also H. The liquid level of the slag removal fluid inside the cutting bed 1 is flush with the lower end face of the connecting block 9. Slag removal fluid refers to a liquid that can separate slag from the support. It usually refers to an alkaline cleaner or an oxygen acidifier.

[0040] Working principle: The support member 8 on one side of the connecting block 9 is named the first support member 801, and the second support member 802 on the other side of the connecting block 9 is named the second support member 802. Initially, the first support member 801 is located on the upper side of the connecting block 9, and the second support member 802 is located on the lower side of the connecting block 9. The first support member 801 extends above the connecting block 9, and the apex of the second support member 802 is located inside the connecting block 9. The ends of the two corresponding extrusion blocks 18 of the second support member 802 contact and block the apex of the second support member 802. The slag removal liquid inside the connecting block 9 is flush with the lower end surface of the connecting block 9. The spring 23 is in a compressed state and has elastic potential energy.

[0041] The plate to be cut is placed on multiple first support members 801, and the first support members 801 support the plate.

[0042] The first electric slide rail 4 is activated, and the first electric slider 16 drives the electrically controlled telescopic rod 5 to move along the length of the cutting bed 1, thereby causing the laser cutting head 7 to move along the length of the electrically controlled telescopic rod 5. The second electric slide rail 6 is activated, and the second electric slider 17 drives the laser cutting head 7 to move along the width of the cutting bed 1. The electrically controlled telescopic rod 5 moves the laser cutting head 7 up and down, thereby adjusting the position of the laser cutting head 7. The laser cutting head 7 is then activated to cut the sheet material.

[0043] During the cutting process, molten slag generated by the laser cutting head 7 may fall onto the first support member 801, specifically onto its apex, sides, or edges. If the slag accumulates at the apex of the first support member 801, the sheet material cannot be placed horizontally on the cutting bed 1, thus affecting the actual cutting accuracy. If the slag falls onto the sides or edges of the first support member 801 and is not cleaned promptly, it will gradually accumulate, increasing in height and also preventing the sheet material from being placed horizontally on the first support member 801, thus affecting the accuracy of the sheet material cutting process.

[0044] After the sheet metal is cut, it is removed from the cutting bed 1. When it is necessary to clean the slag on the first support 801, the first electric push rod 14 is activated. The first electric push rod 14 pushes the first slider 12 to move, the rack 11 moves, the rack 11 drives the gear 10 to rotate, and the gear 10 drives the connecting block 9 to rotate until the connecting block 9 rotates 90 degrees. Figure 12 As shown, the connecting block 9 is set horizontally at this time.

[0045] Then, the second electric push rod 28 is activated, which drives the connecting rod 20 to move. The connecting rod 20 drives the connecting block 9 to move, and the sliding rod 19 in the first support member 801 moves out of the corresponding clearance groove 27. The sliding rod 19 in the second support member 802 moves towards the second support member 802, pushing the second support member 802 outward from the connecting block 9, so that the second support member 802 gradually extends outside the connecting block 9. At the same time, the second support member 802 pushes the corresponding pressing block 18 to move, so that the two pressing blocks 18 gradually move away from each other. The pressing block 18 pushes the third slider 22 to slide in the third slide groove 21, thereby further compressing the spring 23.

[0046] As the sliding rod 19 inside the first support member 801 gradually moves outward from the clearance groove 27, losing the support of the sliding rod 19, the third slider 22 slides closer to the first support member 801 under the action of the spring 23, and the extrusion block 18 moves closer to the support member 8. The extrusion block 18 slides along the side of the support member 8, pushing the first support member 801 and causing it to move into the connecting block 9. When the extrusion block 18 moves along the side of the first support member 801, the cutting edge of the extrusion block 18 scrapes and cleans the side of the first support member 801, removing the slag on the side of the first support member 801. When the first support member 801 slides into the connecting block 9, the connecting block 9 scrapes and cleans the side of the first support member 801, removing the slag on the side of the first support member 801.

[0047] like Figure 13 As shown, when the extrusion block 18 slides along the side of the first support member 801, the guide block moves along the guide groove 26. Under the limiting action of the limiting component, the cutting edge of the extrusion block 18 remains in close contact with the side of the first support member 801. If the slag on the side of the first support member 801 solidifies and firmly adheres to the side, when the extrusion block 18 moves along the first support member 801, if the extrusion block 18 cannot scrape off the adhered slag, then due to the obstruction of the slag, the extrusion block 18 cannot continue to move along the first support member 801, and consequently the first support member 801 cannot continue to move into the connecting block 9, so that the apex of the first support member 801 is located outside the connecting block 9, and a portion of the first support member 801 is located outside the connecting block 9.

[0048] If the slag on the side of the first support member 801 solidifies and adheres firmly to the side, when the first support member 801 moves into the connecting block 9, if the connecting block 9 cannot remove the slag adhering to the side of the first support member 801, the first support member 801 cannot move into the connecting block 9 due to the obstruction of the slag, so that part of the first support member 801 is located outside the connecting block 9.

[0049] like Figure 14 As shown, if there is no molten slag blocking the two sides, two side edges and the vertex of the first support member 801, the first support member 801 enters the connecting block 9 under the push of the extrusion block 18, and the two extrusion blocks 18 contact and block the vertex of the first support member 801.

[0050] Therefore, when the second support 802 moves outside the connecting block 9, part of the first support 801 will protrude out of the connecting block 9 due to the obstruction of the molten slag.

[0051] Then, the first electric push rod 14 is activated again, causing the first slider 12 to move, the rack 11 to move, and the gear 10 to rotate, further flipping the connecting block 9. This positions the first support member 801 below the connecting block 9 and the second support member 802 above it. At this point, the second support member 802 is outside the connecting block 9, while the first support member 801, blocked by molten slag, and the molten slag are located outside the connecting block 9, and the first support member 801, not blocked by molten slag, is located inside the connecting block 9. A plate is placed on the second support member 802, and the laser cutting head 7 cuts the plate on the second support member 802.

[0052] The portion of the first support member 801 located outside the connecting block 9 is immersed in the slag removal liquid within the cutting bed 1. The slag removal liquid separates the slag on the first support member 801 from the first support member 801. The first support member 801, which is not blocked by slag, is located inside the connecting block 9 and does not come into contact with the slag removal liquid, thus reducing the impact of the slag removal liquid on the first support member 801.

[0053] After the molten slag separates from the first support member 801, or after the connection between the molten slag and the first support member 801 becomes loose, the pressing block 18 continues to push the first support member 801 under the action of the spring 23, causing the first support member 801 to move into the connecting block 9. This prevents the first support member 801 from being continuously immersed in the molten slag removal liquid, which would affect its service life. As the first support member 801 moves into the connecting block 9, the pressing block 18 and the connecting block 9 scrape off the molten slag removal liquid adhering to the support member 801, preventing the molten slag removal liquid from entering the connecting block 9.

[0054] After the plate on the second support 802 is cut and processed, the slag on the second support 802 is cleaned in the same way.

[0055] This invention also includes a method for cutting mechanical parts, comprising the following steps: S1. Place the board onto multiple support members 8, and the cutting mechanism cuts the board.

[0056] S2. After cutting, remove the plate from the cutting bed 1 and rotate the connecting block 9 90 degrees.

[0057] S3. Then, the extrusion block 18 pushes the support 8 into the connecting block 9, and the extrusion block 18 and the connecting block 9 clean the slag on the support 8.

[0058] S4. When the extrusion block 18 and the connecting block 9 cannot remove the slag on the support member 8, part of the support member 8 is located outside the connecting block 9 due to the obstruction of the slag.

[0059] S5. Continue to rotate the connecting block 9, thereby immersing the portion of the support 8 outside the connecting block 9 in the slag removal liquid inside the cutting bed 1.
