The utility model includes a hanger with a fixing mechanism and an adjusting mechanism for coordinated use. The fixing mechanism includes a vacuum pump, a tube, and a suction cup, with the suction cup slidably inserted into the hanger. Both ends of the hanger are equipped with receiving mechanisms that cooperate with the suction cup. The receiving mechanism includes a stepper motor and a rotating rod, with the stepper motor fixedly installed on both sides of the top of the hanger.

This allows for stable support of plates of different sizes, preventing the plates from falling due to insufficient adhesion, thus improving practicality and safety.

Description

Technical Field

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

[0002] Laser cutting uses an invisible beam of light instead of a traditional mechanical blade, and features high precision and fast cutting speed. However, when processing hard sheet materials, laser cutting machines require a hoisting device to lift the sheet material onto the worktable.

[0003] However, existing laser cutting machine worktable plate lifting devices lack corresponding plate-bearing mechanisms when lifting rigid plates, thus failing to effectively catch plates that fall due to poor adhesion, resulting in poor safety.

[0004] To address the aforementioned problems, this application proposes a laser cutting machine worktable plate hoisting device to solve these problems. Utility Model Content

The rotating rod is rotatably inserted into both sides of the hanger, and a gear 2 is fixedly fitted at its bottom end. Two rotating holes are opened through the hanger, and the rotating rod is rotatably inserted into the holes.

The rotating plate is slidably inserted into the slot. An electric push rod is fixedly installed at the end of the rotating plate. The output end of the electric push rod slides through the rotating plate and is fixedly fitted with a shaped frame at its end. A through hole is opened through the shaped frame, and the end of the output end of the electric push rod is fixedly inserted into the through hole. A guide rod is fixedly inserted into the top of the shaped frame and slides through the rotating plate. A through hole is opened through the end of the shaped frame, and the guide rod is fixedly inserted into the through hole. A guide hole is opened through the end of the rotating plate, and the guide rod slides into the guide hole.

[0008] Preferably, the adjustment mechanism includes a sliding plate, which is slidably fitted onto the upper end of the suction cup.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] 1.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example: Figures 1-5 As shown, this utility model provides a lifting device for the worktable plate of a laser cutting machine, including a hanger 1. The hanger 1 is provided with a fixing mechanism 2 and an adjusting mechanism 3 for use. The fixing mechanism 2 includes a vacuum pump, a tube and a suction cup. The suction cup is slidably inserted on the hanger 1, and both ends of the hanger 1 are provided with a receiving mechanism 4 for use with the suction cup.

[0021] The receiving mechanism 4 includes a stepper motor 41 and a rotating rod 42. The stepper motor 41 is fixedly installed on both sides of the top of the hanger 1, and the output end of the stepper motor 41 rotates through the hanger 1 and a gear 43 is fixedly sleeved at its end. The rotating rod 42 is rotatably inserted into both sides of the hanger 1, and a gear 44 is fixedly sleeved at the bottom end of the rotating rod 42. Two rotating holes 13 are opened through the hanger 1, and the rotating rod 42 is rotatably inserted into the rotating holes 13. The rotating holes 13 are provided for the stable rotation of the rotating rod 42. The mechanism provides stability by having gear 44 mesh with gear 43, and both gear 44 and gear 43 have a rotating plate 45 fixedly connected to them. The hanger 1 has symmetrically distributed slots 11, and the rotating plate 45 can be slidably inserted into the slots 11. The hanger 1 has a support plate on its inner bottom side near the stepper motor 41, which works in conjunction with the rotating plate 45. The support plate slides against the rotating plate 45, thus ensuring the stability of the rotating plate 45 after rotation. This is existing technology and will not be elaborated further here. An electric push rod 46 is fixedly installed at the end of the rotating plate 45, and the output end of the electric push rod 46 slides through the rotating plate 45 and is fixedly fitted with a special-shaped frame 47 at its end. The stepper motor 41 and the electric push rod 46 are controlled by a PLC control module to open and close. This is existing technology and will not be described in detail here. A through hole 411 is opened through the special-shaped frame 47, and the end of the output end of the electric push rod 46 is fixedly inserted into the through hole 411. The through hole 411 is set to allow the electric push rod 46 and the... The stable insertion of the irregular frame 47 provides a guarantee. The top of the irregular frame 47 is fixedly inserted with a guide rod 48, and the guide rod 48 slides through the rotating plate 45. The end of the irregular frame 47 is provided with a through hole 49, and the guide rod 48 is fixedly inserted in the through hole 49. The end of the rotating plate 45 is provided with a guide hole 410, and the guide rod 48 slides in the guide hole 410. The cooperation of the through hole 49, the guide rod 48 and the guide hole 410 plays a limiting and guiding role in the movement and adjustment of the irregular frame 47.

[0022] By adopting the above technical solution, when the suction cup is used to fix the board and the material is moved, the four electric push rods 46 will start synchronously, thereby driving the four irregular frames 47 to move down synchronously. When the bottom of the irregular frame 47 is lower than the bottom of the corresponding board, the electric push rods 46 will be turned off. Then, the two stepper motors 41 will start synchronously, thereby driving the two gears 43 to rotate synchronously, which in turn drives the two gears 44 to reverse synchronously, and further drives the adjacent rotating plate 45 to reverse synchronously, thereby driving the adjacent irregular frame 47 to reverse synchronously until the bottom end of the irregular frame 47 moves to the underside of the hoisted board, at which point the stepper motors 41 will be turned off. After the board is hoisted to the appropriate position, the irregular frame 47 can be reset and the material unloaded.

[0023] The adjustment mechanism 3 includes a slide plate 31, which is slidably fitted onto the upper end of the suction cup. A spring 32 is fixedly installed on the top of one side of the slide plate 31, and a collar 33 is fixedly connected to the end of the spring 32. The collar 33 is fixedly fitted onto the top of the suction cup. A rod 34 is fixedly inserted into the other side of the slide plate 31. An array of insertion holes 12 are provided on the hanger 1, and the rod 34 can be slidably inserted into the insertion holes 12. A grip 35 is integrally formed at one end of the slide plate 31, and the outer wall of the grip 35 is covered with an anti-slip texture. The anti-slip texture can increase friction and facilitate operation.

[0024] By adopting the above technical solution, when in use, the position of the suction cup is adjusted according to the size of the plate to be lifted. At this time, the four grips 35 need to be moved up in sequence, which can drive the corresponding slide plate 31 to move up, and then drive the corresponding insertion rod 34 to move up and squeeze the corresponding spring 32. When the insertion rod 34 is completely separated from the corresponding insertion hole 12, the grips 35 are moved horizontally, which can drive the corresponding suction cup to move horizontally. When the suction cup moves to the appropriate position, the grips 35 are released. Then the spring 32 will drive the corresponding slide plate 31 to reset, which can drive the corresponding insertion rod 34 to reset, and then the insertion rod 34 can be inserted into another corresponding insertion hole 12.

[0025] Working principle: When in use, adjust the position of the suction cup according to the size of the plate to be lifted. At this time, the four grips 35 need to be moved up in sequence, which can drive the corresponding slide plate 31 to move up, and then drive the corresponding insertion rod 34 to move up and squeeze the corresponding spring 32. When the insertion rod 34 is completely separated from the corresponding insertion hole 12, move the grips 35 horizontally, which can drive the corresponding suction cup to move horizontally. When the suction cup moves to the appropriate position, release the grips 35. Then the spring 32 will drive the corresponding slide plate 31 to return to the original position, which can drive the corresponding insertion rod 34 to return to the original position, and then allow the insertion rod 34 to be inserted into another corresponding insertion hole 12.

[0026] In addition, when the suction cups adsorb and fix the board and start moving the material, the four electric push rods 46 will start synchronously, thereby driving the four irregular frames 47 to move down synchronously. When the bottom of the irregular frame 47 is lower than the bottom of the corresponding board, the electric push rods 46 will be turned off. Then, the two stepper motors 41 will start synchronously, thereby driving the two gears 43 to rotate synchronously, which in turn drives the two gears 44 to reverse synchronously, and further drives the adjacent rotating plate 45 to reverse synchronously, thereby driving the adjacent irregular frame 47 to reverse synchronously until the bottom end of the irregular frame 47 moves to the underside of the hoisted board, at which point the stepper motors 41 will be turned off. After the board is hoisted to the appropriate position, the irregular frame 47 will be reset and the material will be unloaded.

[0027] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
