[0030] 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.

[0031] This embodiment describes a laser cutting device for processing automotive parts, such as... Figures 1 to 8 As shown, it includes a machine base 1, a cutting lifting column 2 is provided at the middle of the rear side of the top of the machine base 1, a laser cutting device 3 is provided on the cutting lifting column 2, and a cutting frame 4 is provided at the middle of the top of the machine base 1.

[0032] The fixing mechanism 5 includes two lifting adjustment columns 501, which are respectively located on the rear side of the top of the machine platform 1 and on the left and right sides of the cutting lifting column 2.

[0033] In this embodiment, as Figure 2 As shown, the fixing mechanism 5 includes a lifting groove 502, a fixing groove 503, a lifting fixing plate 504, and a lifting box 505. The lifting groove 502 is opened in the middle of the front and rear sides of the lifting adjusting column 501. The fixing groove 503 is opened in the middle of the side of the lifting adjusting column 501 away from the cutting lifting column 2. There are two lifting fixing plates 504, and one end of each plate is movably installed in the lifting groove 502. The lifting box 505 is movably installed on the rear side of the lifting adjusting column 501. The two lifting fixing plates 504 are fixedly installed at the left and right ends of the lifting box 505 on the side of the lifting adjusting column 501, respectively.

[0034] The lifting box 505 can drive the telescopic plate 506 to move up and down within the lifting groove 502.

[0035] In this embodiment, as Figure 3 As shown, the fixing mechanism 5 includes a telescopic plate 506, a rack 507, a first return spring 508, and a connecting block 509. There are two telescopic plates 506, which are respectively movably installed at the upper and lower ends inside the lifting box 505. There are two racks 507, which are respectively fixedly installed at the ends of the two telescopic plates 506 near the middle of the inside of the lifting box 505. A spring groove is opened between the end of the rack 507 away from the telescopic plate 506 connected to it and the side end of the lifting box 505. There are two first return springs 508, which are respectively fixedly installed in the two spring grooves. There are two connecting blocks 509, which are respectively fixedly installed at the ends of the two telescopic plates 506 located outside the side end of the lifting box 505.

[0036] The telescopic plate 506 drives the connecting block 509 and the fixed column 510 to move away from the lifting adjustment column 501, thereby releasing the clamping state of the fixed column 510 and the lifting adjustment column 501 in the fixed groove 503. By driving the fixed column 510 to move towards the lifting adjustment column 501, the lifting box 505 is fixed, so that the lifting fixing plate 504 fixes the plate on the cutting frame 4.

[0037] In this embodiment, as Figure 3As shown, the fixing mechanism 5 includes a fixing column 510, a first gear 511, a worm gear 512, a worm 513, and a throttle 514. There are two fixing columns 510, which are respectively fixedly installed on one end of two connecting blocks 509 near the lifting adjustment column 501. The two fixing columns 510 are respectively movably installed in the fixing grooves 503 opened on the two lifting adjustment columns 501. The first gear 511 is movably installed in the middle of the inside of the lifting box 505. Two racks 507 are respectively located on the upper and lower sides of the first gear 511 and mesh with the first gear 511. The worm gear 512 is located in the middle of the rear side of the lifting box 505 and is fixedly installed in the middle of the first gear 511. The worm 513 is located at the bottom end of the worm gear 512 and meshes with the worm gear 512. Several connecting columns are fixedly installed on the bottom rear side of the lifting box 505. The worm 513 is movably installed in the connecting columns. There are two throttles 514, which are respectively fixedly installed at both ends of the worm 513.

[0038] By turning the throttle 514, the worm gear 512 is driven to rotate. When the worm gear 512 rotates, it drives the first gear 511 to rotate. When the first gear 511 rotates, it drives the two racks 507 located on its upper and lower sides to move in opposite directions. This causes the two telescopic plates 506 to move along with the racks 507 to the outside of the lifting box 505 through the connecting block 509, which in turn drives the fixing column 510 to move. At this time, the two fixing columns 510 are released from the clamping state with the fixing groove 503, so that the lifting box 505 can drive the telescopic plates 506 to move up and down in the lifting groove 502.

[0039] At other levels, this embodiment also provides a deburring mechanism 6 for removing burrs generated after cutting, such as... Figure 4 and Figure 5 As shown, the deburring mechanism 6 includes a support platform 601, the four corners of which are located at the middle of the top rear side of the inner side of the cutting frame 4.

[0040] In this embodiment, as Figure 4 and Figure 5 As shown, the deburring mechanism 6 includes a movable groove 602, a gear groove 603, a connecting shaft 604, a second gear 605, and a lower locking wheel 606. The movable groove 602 is located in the middle of the rear side of the top of the cutting frame 4. The gear groove 603 is located in the middle of the top of the support platform 601. The connecting shaft 604 is fixedly installed in the middle of the gear groove 603. The second gear 605 is movably sleeved on the bottom end of the connecting shaft 604 and is movably installed in the gear groove 603. The lower locking wheel 606 is movably sleeved on the outside of the connecting shaft 604 and is fixedly installed on the top end of the second gear 605.

[0041] The second gear 605 drives the lower locking wheel 606 to rotate outside the connecting shaft 604.

[0042] In this embodiment, as Figure 4 and Figure 5 As shown, the deburring mechanism 6 includes an upper engaging wheel 607, a baffle 608, a second return spring 609, a rotating plate 610, and a grinding groove 611. The upper engaging wheel 607 is movably mounted on the upper end of the connecting shaft 604, and the bottom end of the upper engaging wheel 607 is movably mounted on the top end of the lower engaging wheel 606. The baffle 608 is movably sleeved outside the connecting shaft 604 and fixedly mounted on the top end of the upper engaging wheel 607. The second return spring 609 is located between the second gear 605 and the baffle 608 and is movably sleeved outside the lower engaging wheel 606 and the upper engaging wheel 607. The end of the rotating plate 610 near the connecting shaft 604 is movably mounted on the top end of the connecting shaft 604 and fixedly mounted on the top end of the baffle 608. The grinding groove 611 is opened at the end of the rotating plate 610 away from the connecting shaft 604.

[0043] The rotating plate 610 is pressed down by the plate, which drives the upper locking wheel 607 to engage with the lower locking wheel 606. When the second gear 605 rotates, the upper locking wheel 607 drives the baffle 608 to rotate, causing the rotating plate 610 to rotate slowly.

[0044] In this embodiment, as Figure 4 and Figure 5 As shown, the deburring mechanism 6 includes a grinding motor 612, a third return spring 613, a grinding wheel 614, a collection net 615, and a water tank 616. The grinding motor 612 is fixedly installed at the bottom center of the rotating plate 610 away from the connecting shaft 604. The output shaft of the grinding motor 612 is movably installed in the middle of the grinding groove 611. The third return spring 613 is fixedly installed between the middle of the side end of the movable groove 602 and the side wall of the rotating plate 610. The grinding wheel 614 is fixedly installed at the end of the output shaft of the grinding motor 612 located in the grinding groove 611. The top of the grinding wheel 614 is on the same plane as the top of the rotating plate 610. The collection net 615 is fixedly installed at the top of the inside of the cutting frame 4. The water tank 616 is movably installed inside the cutting frame 4.

[0045] The grinding motor 612 drives the grinding wheel 614 to rotate at high speed. When the rotating plate 610 rotates, the grinding wheel 614 grinds and removes the burrs generated by the cutting process at the bottom of the plate. The burr debris falls onto the collection net 615, and the coolant during processing passes through the collection net 615 into the water tank 616 for collection.

[0046] At other levels, this embodiment also provides a transmission mechanism 7 for performing transmission, such as... Figure 6 to 8 As shown, the transmission mechanism 7 includes a lifting toothed plate 701. The top of the lifting toothed plate 701 is located at the middle of the rear side of the bottom end of the laser cutting device 3 and is located behind the cutting lifting column 2.

[0047] In this embodiment, as Figures 6 to 8 As shown, the transmission mechanism 7 includes a first gear carrier 702, a third gear 703, a fourth gear 704, a first transmission shaft 705, a fifth gear 706, a transmission chain belt 707, and a first pulley 708. The first gear carrier 702 is fixedly installed at the middle of the rear side of the top of the machine base 1 and is located between the cutting lifting column 2 and the lifting box 505. The two ends of the third gear 703 are movably installed between the top ends of the first gear carrier 702. The fourth gear 704 is fixedly installed at one end of the third gear 703 located outside the first gear carrier 702. A drive shaft 705 is movably mounted between the bottom ends of the first gear carrier 702. A fifth gear 706 is fixedly mounted on the end of the first drive shaft 705 located outside the first gear carrier 702 and on the same side as the fourth gear 704. The top end of the drive chain 707 is engaged and movably sleeved on the fourth gear 704, and the bottom end of the drive chain 707 is engaged and movably sleeved on the fifth gear 706. A first pulley 708 is fixedly mounted on the end of the first drive shaft 705 located outside the first gear carrier 702 and away from the fifth gear 706.

[0048] By activating the laser cutting device 3, the laser cutting device 3 is controlled to descend for cutting. At the same time as the laser cutting device 3 descends, the lifting gear plate 701 is driven to descend, causing the third gear 703 to rotate forward, driving the fourth gear 704 to rotate, and then driving the fifth gear 706 to rotate through the transmission chain belt 707, so that the first transmission shaft 705 follows the fifth gear 706 to rotate.

[0049] In this embodiment, as Figures 6 to 8 As shown, the transmission mechanism 7 includes a second gear carrier 709, a ratchet 710, a second pulley 711, a transmission belt 712, a transmission wheel 713, a ratchet tooth 714, and a fourth return spring 715. The second gear carrier 709 is fixedly installed at the top of the machine base 1 and located between the cutting lifting column 2 and the cutting frame 4. The ratchet 710 is fixedly mounted with an input rod, which is movably installed at the middle of the top of the second gear carrier 709. The second pulley 711 is fixedly installed at the end of the input shaft away from the ratchet 710. The drive belt 712 is movably sleeved on the first pulley 708 and the second pulley 711 respectively. The transmission wheel 713 is movably sleeved on the side of the ratchet 710 away from the second pulley 711. The transmission wheel 713 has several evenly distributed tooth grooves on the side near the ratchet 710. Several ratchet teeth 714 are movably installed in the tooth grooves. The ratchet teeth 714 are movably connected to the ratchet 710. Several fourth return springs 715 are fixedly installed on the side wall of the tooth groove and the side wall of the ratchet teeth 714 respectively.

[0050] The transmission belt 712 drives the second pulley 711 to rotate. At this time, the second pulley 711 drives the input shaft to rotate, so that the ratchet 710 rotates with the input. When the third gear 703 rotates forward, the ratchet 710 also rotates forward. At this time, the ratchet 710 cannot engage with the ratchet tooth 714, and the transmission wheel 713 does not rotate.

[0051] In this embodiment, as Figures 6 to 8 As shown, the transmission mechanism 7 includes a guard plate 716, a second transmission shaft 717, a first bevel gear 718, a third gear carrier 719, a second bevel gear 720, a third transmission shaft 721, a sixth gear 722, and a retaining ring 723. The guard plate 716 is fixedly installed on the side of the transmission wheel 713 near the second pulley 711. The guard plate 716 is movably sleeved on the outside of the input shaft. The end of the second transmission shaft 717 near the transmission wheel 713 is fixedly installed in the middle of the transmission wheel 713. The second transmission shaft 717 is inserted into and movably installed at the top of the second gear carrier 709. The first bevel gear 718 is fixedly installed on the end of the second transmission shaft 717 away from the second gear carrier 709. The third gear frame 719 is fixedly installed at the top of the machine base 1 and located between the cutting lifting column 2 and the cutting frame 4, and is located to the right of the second gear frame 709. The second bevel gear 720 is movably installed in the middle of the top of the third gear frame 719. The first bevel gear 718 is located to the left of the top of the second bevel gear 720 and meshes with the second bevel gear 720. The bottom end of the third drive shaft 721 is fixedly installed in the middle of the second bevel gear 720. The sixth gear 722 is fixedly installed at the top of the third drive shaft 721. The fixing ring 723 is fixedly sleeved on the bottom end of the cutting lifting column 2. The third drive shaft 721 is movably installed at the end of the fixing ring 723 near the cutting frame 4.

[0052] The first bevel gear 718 rotates simultaneously with the transmission wheel 713 via the second transmission shaft 717. When the first bevel gear 718 rotates, the second bevel gear 720 drives the third transmission shaft 721 to rotate, causing the sixth gear 722 to rotate simultaneously with the third transmission shaft 721.

[0053] Working Principle: In use, the material to be cut is first placed on the cutting frame 4. After adjusting the drilling position to be directly below the drill bit, the handle 514 is turned. The handle 514 drives the worm gear 512 to rotate. When the worm gear 512 rotates, it drives the first gear 511 to rotate. When the first gear 511 rotates, it drives the two racks 507 located above and below it to move in opposite directions. This causes the two telescopic plates 506 to move along with the racks 507 to the outside of the lifting box 505 through the connecting block 509, which in turn drives the fixing column 510. At this time, the two fixing columns 510 are released from the clamping state with the fixing groove 503, allowing the lifting box 505 to drive the telescopic plates. 506 moves up and down in the lifting groove 502, pressing the telescopic plate 506 tightly onto the plate to be cut. Then, the handle 514 is rotated in the opposite direction, causing the fixing column 510 to retract into the fixing groove 503 and clamp with the lifting adjustment column 501, thereby fixing the position of the lifting box 505 and fixing the plate to be cut on the cutting frame 4. At the same time, the cutting frame 4 presses down the rotating plate 610, making the top plane of the rotating plate 610 flush with the top plane of the connecting shaft 604. The fixing mechanism 5 fixes the plate to be processed on the cutting frame 4, preventing the plate from shifting during cutting and deburring, and ensuring the stability of cutting and deburring.

[0054] Once the material to be processed is fixed, the laser cutting device 3 is activated and controlled to descend for cutting. Simultaneously, the laser cutting device 3 descends, causing the lifting gear plate 701 to descend as well, resulting in the third gear 703 rotating forward and driving the fourth gear 704 to rotate. This, in turn, drives the fifth gear 706 to rotate via the transmission chain belt 707, causing the first transmission shaft 705 to rotate along with the fifth gear 706. At this time, the first pulley 708 rotates along with the first transmission shaft 705. As the first pulley 708 rotates, the transmission... Belt 712 drives the second pulley 711 to rotate, which in turn drives the input shaft to rotate, causing the ratchet 710 to rotate with the input. When the third gear 703 rotates forward, it drives the ratchet 710 to rotate forward as well. At this time, the ratchet 710 cannot engage with the ratchet tooth 714, and the transmission wheel 713 does not rotate. When the laser cutting device 3 moves upward after cutting, the lifting gear plate 701 drives the third gear 703 to rotate backward, causing the ratchet 710 to rotate backward. At this time, the ratchet 710 engages with the ratchet tooth 714. When the ratchet 710 rotates, it drives the transmission wheel 713 to rotate simultaneously. This, in turn, causes the first bevel gear 718 to rotate along with the transmission wheel 713 via the second transmission shaft 717. When the first bevel gear 718 rotates, it drives the third transmission shaft 721 to rotate via the second bevel gear 720, causing the sixth gear 722 to rotate along with the third transmission shaft 721. When the sixth gear 722 rotates, it drives the second gear 605 to rotate. Because the rotating plate 610 is pressed down, it causes the upper engaging wheel 607 to engage with the lower engaging wheel 606. When the second gear 605 rotates, it drives the baffle 608 to rotate through the upper locking wheel 607, causing the rotating plate 610 to rotate slowly. When the rotating plate 610 rotates, it controls the start of the grinding motor 612, which drives the grinding wheel 614 to rotate at high speed. When the rotating plate 610 rotates, the grinding wheel 614 grinds and removes the burrs generated at the bottom of the plate due to the cutting process. The burr debris falls onto the collection net 615, and the coolant during processing passes through the collection net 615 into the water tank 616 for collection.

[0055] After deburring is completed, turn the handle 514 to release the fixed column 510 from the clamping state of the fixed groove 503. After lifting the lifting fixed plate 504, the plate is taken out. At this time, under the elastic force of the second return spring 609, the rotating plate 610 drives the upper locking wheel 607 to rise. At this time, the upper locking wheel 607 is no longer locked with the lower locking wheel 606. At this time, under the elastic force of the third return spring 613, the rotating plate 610 returns to the position before the plate was placed.
