[0002] 3D printing, also known as additive manufacturing, is an emerging manufacturing technology that has experienced rapid development in recent years. It has evolved from initially being able to print simple plastic models to being able to print various high-performance materials such as metals and ceramics. Its applications have also expanded from simple prototyping to multiple key fields such as industrial production, medicine, and aerospace.

[0003] Existing devices either require manual disassembly and installation of auxiliary components to raise or lower the worktable when encountering objects of different sizes, which is cumbersome, or they simply lack height adjustment functionality, forcing them to abandon the printing of some large or small objects, greatly limiting the application range of the equipment. To address these issues, we have developed a laser 3D printing device with a 360-degree rotating worktable. Utility Model Content

[0023] This utility model provides an improved laser 3D printing device with a 360-degree rotating worktable. The technical solution of this utility model is as follows:

[0024] like Figure 1 - Figure 5As shown, a laser 3D printing device with a 360-degree rotating worktable includes a worktable 1. A gear disk 2 is rotatably connected to the upper surface of the worktable 1. Two symmetrically arranged cylinders 3 are fixedly connected to the upper surface of the gear disk 2. A round rod 4 is slidably connected to the inner wall of each of the two cylinders 3. The upper ends of the two round rods 4 are fixedly connected to the same disk 5. A hollow square rod 6 is rotatably connected to the lower end of the disk 5. A threaded rod 7 is threadedly connected to the inner wall of the hollow square rod 6. The lower end of the threaded rod 7 penetrates the upper surface of the worktable 1 and extends into the interior of the worktable 1. A first pulley 8 is fixedly connected to the lower end of the threaded rod 7. A limiting sleeve 9 is fixedly connected to the upper surface of the worktable 1. The inner wall of the limiting sleeve 9 is slidably connected to the side wall of the hollow square rod 6. A square box 10 is fixedly connected to the upper surface of the worktable 1. The upper surface of the worktable 1 rotates... A meshing gear 11 is connected, and the surface of the meshing gear 11 meshes with the surface of the gear disk 2. A hollow round rod 12 is provided on the inner wall of the square box 10. The upper end of the hollow round rod 12 passes through the inner wall of the square box 10 and extends upward. A circular limiting piece 13 is fixedly connected to the surface of the hollow round rod 12. A pressure plate 14 is fixedly connected to the upper end of the hollow round rod 12. A first spring 15 is sleeved on the surface of the hollow round rod 12. One end of the first spring 15 is fixedly connected to the upper surface of the square box 10, and the other end of the first spring 15 is fixedly connected to the lower surface of the pressure plate 14. A second pulley 16 is rotatably connected to the inner wall of the worktable 1. The second pulley 16 and the first pulley 8 are sleeved with the same belt 17. A motor 18 is fixedly connected to the inner wall of the worktable 1. A limiting groove 19 is opened on the output end surface of the motor 18.

[0025] Furthermore, a ring 20 is fixedly connected to the lower end of the hollow round rod 12, and a sleeve 21 is provided below the ring 20. An annular groove 22 is provided at the upper end of the sleeve 21. The inner wall of the annular groove 22 is rotatably connected to the surface of the ring 20. The sleeve 21 is moved by the displacement of the hollow round rod 12, so that the sleeve 21 can adjust the height of the disk 5 or rotate the disk 5 at different positions.

[0026] Furthermore, a limiting strip 23 is fixedly connected to the inner wall of the sleeve 21. The side wall of the limiting strip 23 matches the inner wall of the limiting groove 19. Multiple annularly arranged strip grooves 24 are opened on the surface of the sleeve 21. Two symmetrically arranged second springs 25 are fixedly connected to the inner wall of each of the multiple strip grooves 24. The other end of the two second springs 25 is fixedly connected to the same limiting block 26. The sleeve 21 maintains a rotating state when it is displaced at the output end of the motor 18.

[0027] Furthermore, the inner wall of the second pulley 16 is provided with a plurality of annular first strip-shaped limiting grooves 27. The inner wall of the first strip-shaped limiting groove 27 matches the side wall of the limiting block 26. When the limiting block 26 of the sleeve 21 enters the first limiting groove 27, it drives the second pulley 16 to rotate, thereby adjusting the height of the disc 5.

[0028] Furthermore, the inner wall of the meshing gear 11 is provided with a plurality of annular second strip-shaped limiting grooves 28. The inner wall of the second strip-shaped limiting groove 28 matches the side wall of the limiting block 26. When the limiting block 26 of the sleeve 21 enters the second limiting groove 28, it drives the meshing gear 11 to rotate, thereby causing the disc 5 to rotate.

[0029] Furthermore, two symmetrically arranged strip-shaped fixing plates 29 are fixedly connected to the upper surface of the workbench 1. The side walls of the two strip-shaped fixing plates 29 are fixedly connected to the same sliding rod 30. The side wall of the sliding rod 30 is slidably connected to a laser printer 31. By adjusting the laser printer 31, laser printing can be adapted to different positions.

[0030] Working principle: First, the sleeve 21 is brought into the meshing gear 11 by the rebound of the first spring 15. Then, the limiting block 26 is sent into the second strip-shaped limiting groove 28 by the action of the second spring 25. At this time, the motor 18 is started to drive the meshing gear 11 to mesh with the gear disk 2. The two cylinders 3 and the round rod 4 cause the disk 5 to rotate, which facilitates the adjustment of the laser printing position. At the same time, when printing objects of different heights, the pressure plate 14 can be pressed down to bring the sleeve 21 into the first strip-shaped limiting groove 27. The rotation of the second pulley 16 drives the hollow square rod 6 to rise or fall, thereby adjusting the height of the disk 5.
