Description

Technical Field

[0001] This utility model relates to the field of laser cutting machines, specifically a plate positioning device for a laser cutting machine. Background Technology

[0002] Laser cutting machines are high-precision, high-efficiency cutting devices widely used in industrial production. Their working principle involves focusing a high-power-density laser beam onto the workpiece surface, causing the material to melt, evaporate, or burn instantaneously, thus achieving cutting. The specific process includes laser emission, transmission, focusing, and cutting.

[0003] A specific example of a plate positioning device for a laser cutting machine can be found in application number CN202420100708.3. This laser cutting machine includes a main body, a transverse moving component, a laser gun assembly, and a longitudinal moving component. Two symmetrical sliding rods are fixed to the main body, and a transverse moving component is movably connected to these rods. A first motor is fixed to the middle of one side of the main body, and the output shaft of the first motor extends into the main body, where an eccentric roller is fixed. The two ends of the eccentric roller are movably sleeved with the inner wall of the main body. This laser cutting machine, through a conical support frame, allows waste chips to fall directly through the gaps between the support frames after cutting, preventing waste chips from falling onto the worktable and causing subsequent cleaning difficulties. Furthermore, the output shaft of the first motor causes the sliding plate to vibrate.

[0004] The aforementioned device does not include a component for fixing the position of the workpiece. When cutting, the existing device cannot fix the workpiece, which makes it easy for the workpiece to move during the cutting process, resulting in a deviation in the cutting position and scrapping the workpiece. Therefore, a plate positioning device for a laser cutting machine is proposed to address the above problem. Utility Model Content

[0005] To overcome the shortcomings of existing technology, the existing devices do not have a component for fixing the position of the workpiece. When cutting, because the existing devices cannot fix the workpiece, the position of the workpiece is easily moved during the cutting process, resulting in the offset of the cutting position and the scrapping of the workpiece. This utility model proposes a plate positioning device for a laser cutting machine.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a plate positioning device for a laser cutting machine, comprising a base; the top end of the base is fixedly connected to the bottom end of the cutting table, and a fixing mechanism is provided at the top end of the base;

[0026] The fixing mechanism includes a fifth fixing block 10, which is disposed at the front and rear ends of the top left and right sides of the base 1. The bottom end of the fifth fixing block 10 is welded to the top end of the base 1. The rear end of the fifth fixing block 10 at the front end of the base 1 is welded to the front end of the first guide rod 11. The front end of the fifth fixing block 10 at the rear end of the base 1 is welded to the rear end of the first guide rod 11. A moving block 12 is sleeved on the outside of the first guide rod 11, and the first guide rod 11 and the moving block 12 are slidably connected. One side of the moving block 12 is welded to one side of the first sleeve rod 13. A second sleeve rod 14 is sleeved inside the first sleeve rod 13, and the first sleeve rod 13 and the second sleeve rod 14 are slidably connected. One side of the second sleeve rod 14 inserted inside the first sleeve rod 13 is welded to one side of the first limiting block 15.

[0027] During operation, the moving block 12 is pushed, causing it to move along the outside of the first guide rod 11 inside the fifth fixed block 10 until it reaches the side end of the cutting part that needs to be fixed. When the second sleeve rod 14 moves, it simultaneously causes the first limiting block 15 to move along the inside of the first sleeve rod 13. The first limiting block 15 can also prevent the second sleeve rod 14 from moving out of the inside of the first sleeve rod 13.

[0028] Furthermore, a movable rod 16 is sleeved inside the second sleeve rod 14, and the second sleeve rod 14 and the movable rod 16 are slidably connected. One side of the movable rod 16, which is sleeved inside the second sleeve rod 14, is welded to one side of the second limiting block 17, and the other side of the movable rod 16 is welded to one side of the first fixing block 18.

[0029] During operation, the moving rod 16 is pulled, causing it to move outward along the inside of the second sleeve rod 14. At the same time, the second limiting block 17 at the left end of the moving rod 16 moves along the inside of the second sleeve rod 14, and the second limiting block 17 can prevent the moving rod 16 from disengaging from the inside of the second sleeve rod 14.

[0030] Furthermore, a threaded rod 19 is fitted inside the first fixing block 18, and the first fixing block 18 is threadedly connected to the threaded rod 19. The top end of the threaded rod 19 is welded to the bottom end of the rotating handle 20.

[0031] During operation, the first fixing block 18 is moved above the position to be fixed, and the rotating handle 20 is turned to drive the threaded rod 19 to rotate along the inside of the first fixing block 18, while moving downwards.

[0032] Furthermore, the bottom end of the threaded rod 19 is welded to the top end of the rotating block 21, a second fixing block 22 is sleeved on the outside of the rotating block 21, and the rotating block 21 and the second fixing block 22 are rotatably connected. The bottom end of the second fixing block 22 is welded to the top end of the base plate 23, and the bottom end of the base plate 23 is glued to the top end of the anti-slip block 26.

[0033] During operation, the threaded rod 19 rotates, causing the rotating block 21 to rotate along the inside of the second fixed block 22, and at the same time pushing the base plate 23 to move downward until the anti-sliding block 26 at the bottom of the base plate 23 presses against the top of the cutting part.

[0035] During operation, the base plate 23 moves, which in turn drives the third guide rod 24 to move downward along the inside of the first fixed block 18. The third limiting block 25 at the top of the first fixed block 18 can prevent the first fixed block 18 from detaching from the inside of the base plate 23.

[0036] Furthermore, the other side of the movable block 12 is welded to one end of the fourth fixed block 29, and the other end of the fourth fixed block 29 is sleeved on the outside of the second guide rod 28. The fourth fixed block 29 is slidably connected to the second guide rod 28. The front and rear ends of the second guide rod 28 are also provided with third fixed blocks 27, and one end of the second guide rod 28 is welded to one end of the third fixed block 27. The bottom end of the third fixed block 27 is welded to the top end of the base 1.

[0037] During operation, the moving block 12 moves, causing the fourth fixed block 29 to move along the outside of the second guide rod 28 inside the third fixed block 27.

[0038] Working principle: When it is necessary to fix the cut part, first push the moving block 12, which moves along the outside of the first guide rod 11 inside the fifth fixing block 10 until it reaches the side of the cut part that needs to be fixed. Then pull the moving rod 16, which moves outward along the inside of the second sleeve rod 14. At the same time, the second limiting block 17 on the left side of the moving rod 16 moves along the inside of the second sleeve rod 14. The second limiting block 17 can prevent the moving rod 16 from disengaging from the inside of the second sleeve rod 14. When the moving rod 16 is fully pulled out, continue to pull, which moves the second sleeve rod 14 along the inside of the first sleeve rod 13. When the second sleeve rod 14 moves, it simultaneously moves the first limiting block 15 along the inside of the first sleeve rod 13. The first limiting block 15 can also prevent the second sleeve rod 14 from disengaging from the inside of the first sleeve rod 13. Move the first rod 13 out of the house until the first fixing block 18 is above the position to be fixed. Then turn the handle 20 to drive the threaded rod 19 to rotate along the inside of the first fixing block 18 and move downwards. When the threaded rod 19 rotates, it drives the rotating block 21 to rotate along the inside of the second fixing block 22 and pushes the base plate 23 downwards until the anti-sliding block 26 at the bottom of the base plate 23 is pressed against the top of the cutting part. When the base plate 23 moves, it drives the third guide rod 24 to move downwards along the inside of the first fixing block 18. The third limiting block 25 at the top of the first fixing block 18 can prevent the first fixing block 18 from detaching from the inside of the base plate 23. When the moving block 12 moves, it drives the fourth fixing block 29 to move along the outside of the second guide rod 28 inside the third fixing block 27.
