Description

Technical Field

[0001] This utility model relates to the field of 3D printing technology, specifically a high-precision rotary positioning platform for 3D printing spiral structures. Background Technology

[0002] 3D printing technology, also known as additive manufacturing, is a technology that builds three-dimensional solid objects by layering materials. In contrast to traditional additive manufacturing techniques (such as milling and cutting), 3D printing makes the production of complex structures simpler and more efficient by directly converting digital design files into physical objects.

[0003] When fabricating helical structures, 3D printing technology is required, which also necessitates the use of a high-precision rotary positioning platform. Traditional rotary positioning platforms typically utilize two operating modes: rotation and lifting, and cannot combine these two processes, making the operation quite complex. Therefore, there is an urgent need to design a high-precision rotary positioning platform for 3D printing helical structures to solve these problems. Utility Model Content

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.

[0030] Please see Figure 1-6 This utility model provides a technical solution: a high-precision rotary positioning platform for a 3D printed spiral structure, including a support frame 1, a support frame 3 movably disposed inside the support frame 1, and a lifting mechanism 2 for adjusting the height of the support frame 3 installed on the support frame 1. The lifting mechanism 2 includes a threaded column 203 rotatably connected inside the support frame 1, and a reducer 202 is provided at the bottom of the threaded column 203. A drive motor 201 is fixedly installed on the bottom inner wall of the support frame 1, and the output shaft of the drive motor 201 is connected to the input shaft of the reducer 202. The top and bottom of the support frame 3 are provided for the threaded column 203 to pass through. The support frame 3 has a through hole 205. A lifting seat 204, screwed to the outer wall of the threaded column 203, is fixedly installed on the bottom inner wall of the support frame 3. A mounting platform 11 is installed on one side of the top of the support frame 3, and a mounting base hole 14 is opened in the middle of the mounting platform 11. A connecting sleeve 13 is fixed to the bottom of the mounting base hole 14. A T-shaped rotating shaft 9 is rotatably connected to the inner wall of the mounting base hole 14 and the inner wall of the connecting sleeve 13 via a bearing. A rotating platform 4 is fixedly installed on the top of the T-shaped rotating shaft 9. A rotating mechanism 6 for driving the T-shaped rotating shaft 9 is provided on the support frame 3 and the support frame 1. The rotating mechanism 6 includes a lifting seat 204 screwed to the outer wall of the threaded column 203 and a lifting seat 204 opened on one side of the top of the support frame 3. A first mounting hole 605 is provided on one side of the bottom, and a drive shaft 601 is rotatably connected to the inner wall of the first mounting hole 605 via a bearing. Drive wheels 610 are mounted on the outer wall of the drive shaft 601 and the bottom of the outer wall of the T-shaped rotating shaft 9. A drive belt 611 connects the two drive wheels 610. A second mounting hole 606 is provided on one side of the outer wall at both ends of the support frame 3, and a connecting shaft 608 is rotatably connected to the inner wall of the second mounting hole 606 via a bearing. A worm gear 602 is mounted in the middle of the connecting shaft 608, and a worm wheel 603 is mounted on the outer wall of the drive shaft 601. The worm wheel 603 meshes with the worm gear 602. Both ends of one side of the support frame 1 are provided with connecting grooves 607, and racks 604 are fixedly installed on the inner walls of the connecting grooves 607. Gears 609 are installed on both ends of the connecting shaft 608. The gears 609 mesh with the racks 604. The height of the rotating platform 4 can be easily adjusted by the lifting mechanism 2 to meet the height requirements of different 3D printing jobs. The rotating mechanism 6 drives the rotating platform 4 to rotate, which can achieve more precise angle control and stable rotation, meeting the rotation accuracy requirements when printing spiral structures in 3D printing. This integrates the rotation process and the lifting process into one, making the operation process simpler.

[0031] To ensure the stability and accuracy of the lifting of support frame 3, refer to Figure 2 The inner walls on both sides of the support frame 1 are provided with guide grooves 7, and the outer walls at both ends of the support frame 3 are fixedly installed with guide blocks 8 that slide in the guide grooves 7. Through the cooperation of the guide grooves 7 and the guide blocks 8, the support frame 3 plays a guiding role during the lifting and lowering process, so that the lifting and lowering of the support frame 3 is stable and avoids shaking or deviation, thereby improving the overall stability and positioning accuracy of the rotary positioning platform.

[0032] To ensure smoother rotation and reduce wear, refer to... Figure 6 The top of the mounting platform 11 is equipped with pulleys 15 that are evenly distributed, and the rotating platform 4 is attached to the pulleys 15. When the rotating platform 4 rotates, the pulleys 15 can greatly reduce the friction between the rotating platform 4 and the mounting platform 11, making the rotation smoother, extending the service life of the equipment, and also helping to improve the rotation accuracy.

[0033] To protect the connection between the T-shaped rotating shaft 9 and the mounting platform 11, refer to... Figure 4 and Figure 5 The bottom of the T-shaped rotating shaft 9 near the corner is provided with a protective groove 10, and the top of the mounting platform 11 is provided with a protective ring 12 inserted into the protective groove 10 to prevent debris from entering the connection part and affecting the rotation, thereby improving the reliability and stability of the equipment.

[0034] To improve the safety of equipment use, refer to Figure 1 and Figure 2 A protective plate 5 is fixedly installed on the top of the support frame 3, and the protective plate 5 is located between one side of the support frame 1 and one side of the rotating platform 4. The protective plate 5 plays a certain protective role to prevent the items on the rotating platform 4 from accidentally flying out and causing injury during the 3D printing process.

[0035] In summary, the working principle of this utility model is as follows: when it is necessary to adjust the height of the rotating platform 4, the drive motor 201 in the lifting mechanism 2 is started. The output shaft of the drive motor 201 rotates and transmits power to the reducer 202 connected to it. After the reducer 202 reduces the power and increases the torque, it drives the threaded column 203 to rotate, thereby driving the support frame 3 and the mounting platform 11 and rotating platform 4 installed on the support frame 3 to move up and down, so as to achieve height adjustment.

[0036] During the height adjustment process, since gear 609 meshes with rack 604, when support frame 3 moves up and down, it also drives gear 609 to move up and down. As a result, gear 609 and connecting shaft 608 rotate, causing worm 602 to rotate as well. The meshing action of worm 602 and worm wheel 603 drives transmission shaft 601 to rotate, which in turn drives T-shaped rotating shaft 9 and rotating platform 4 to rotate under the transmission action of transmission wheel 610 and transmission belt 611.

[0037] 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.
