[0023] 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.
[0024] Reference Figure 1 and Figure 2 One embodiment of this utility model provides a high-temperature superconducting coil winding fixture, including a base plate 1. Two vertical plates 2 are fixedly connected to the top surface of the base plate 1. Bearings 8 are provided on the inner side of the two vertical plates 2. Rollers 9 are fixedly connected to the inner side of the bearings 8. A rotating assembly is connected to one side of the rollers 9. A coil winding column 10 is provided between the two rollers 9. The rotating assembly includes a driving gear 3, a driven gear 7, a rotating rod 4, a worm gear 19, and a worm 20. The two driven gears 7 are fixedly connected to one side of the two rollers 9 respectively. The driving gear 3 is meshed with the driven gear 7. The rotating rod 4 is fixedly connected to the two driving gears 3. The worm gear 19 is fixedly installed at the center of the rotating rod 4. The worm 20 is meshed with the worm gear 19.
[0025] Specifically, the two ends of the rotating rod 4 are connected to the two vertical plates 2 and rotate with them, thus ensuring the stable rotation of the two driving gears 3. When the worm 20 rotates, it drives the worm wheel 19 to rotate. The worm wheel 19 drives the rotating rods 4 on both sides to rotate synchronously and in the same direction. The rotating rod 4 can then drive the driving gear 3 to rotate. The driving gear 3 drives the driven gear 7 to rotate. The driven gear 7 drives the roller 9 to rotate inside the bearing 8. The rotation of the roller 9 can drive the fixed ring 14 to rotate. The fixed ring 14 drives the mounting ring 15 to rotate. The mounting ring 15 drives the connecting ring 18 inside the roller 9 to rotate. The connecting ring 18 can then drive the coil winding column 10 to rotate stably, greatly reducing the force of the vibration force of the motor 6 transmitted to the coil winding column 10, increasing the stability of the coil winding column 10 during rotation, and indirectly increasing the quality of the winding.
[0026] Reference Figure 1 and Figure 2The top surface of the base plate 1 is provided with a drive seat 5. The outer surface of the drive seat 5 is fixedly mounted with a motor 6 by a fixing bracket, and the output end of the motor 6 is connected to the worm gear 20.
[0027] Specifically, by turning on motor 6, motor 6 can drive worm gear 20 to rotate.
[0028] Reference Figure 1 , Figure 3 and Figure 4 Two rollers 9 are fixedly connected to one side of a fixing ring 14. One side of the two fixing rings 14 is fixedly installed with an mounting ring 15 by a first bolt 16. The surface of the mounting ring 15 is provided with an annular toothed groove 21. The inside of the annular toothed groove 21 is provided with a second bolt 17. A connecting ring 18 is fixedly installed at the center of one side of the mounting ring 15 by a second bolt 17. The two ends of the coil winding column 10 are set on the connecting ring 18.
[0029] Specifically, by removing the first bolt 16, the mounting ring 15 can be released from its fixed position on the fixing ring 14. By removing the oblique second bolt 17, the connecting ring 18 can be released from its fixed position on the mounting ring 15. In use, the second bolt 17 can be removed from the inside of the annular toothed groove 21 to release the connecting ring 18 from its fixed position. Then, by removing the first bolt 16, the mounting ring 15 can be removed from the fixing ring 14. At this point, the connecting ring 18 and the coil winding post 10 can be removed from the roller 9, making it convenient for workers to remove the wound coil and also convenient for workers to change to different shaped winding posts to wind coils of different shapes.
[0030] Reference Figure 1 An electric actuator 11 is fixedly installed on one side of the upright plate 2. One end of the two electric actuators 11 is fixedly connected to an ear plate 12. A limit ring 13 is fixedly connected between the two ear plates 12, and the limit ring 13 is sleeved on the outside of the coil winding column 10.
[0031] Specifically, the telescopic end of the electric actuator 11 is connected to the ear plate 12. By opening the electric actuator 11, the limiting ring 13 is moved. When the limiting ring 13 moves on the coil winding post 10, the length of the winding can be changed. Thus, the length of the coil winding post 10 can be limited according to actual needs, so that the staff can wind coils of different lengths. The connecting ring 18 is also connected to the winding post by a thread. The connecting ring 18 can be rotated to remove the connecting ring 18 from the coil winding post 10. This makes it easier to remove the coil winding post 10 from the device, and the limiting ring 13 will not hinder the removal process of the coil winding post 10.
[0032] Working Principle: When using this device, place it in the designated position. Activating the electric actuator 11 moves the ear plate 12, which in turn moves the limiting ring 13 on the coil winding post 10. This allows adjustment of the winding length of the coil winding post 10, facilitating the winding of coils of different lengths. After winding the coil onto the coil winding post 10, activating the motor 6 drives the worm gear 20 to rotate. The worm gear 20 then drives the worm wheel 19, which in turn drives the rotating rod 4. The rotating rod 4 drives the two driving gears 3, which in turn drive the driven gear 7, which in turn drives the roller 9. The roller 9 then drives the mounting ring 15, which in turn drives the connecting ring 18, which in turn drives the coil winding post 10. When the column 10 rotates, the coil can be wound. When disassembling the coil winding column 10, the second bolt 17 can be removed first. The second bolt 17 can be removed from the inside of the annular tooth groove 21, thereby releasing the fixed state of the connecting ring 18 on the mounting ring 15. Then, the first bolt 16 can be removed, thereby releasing the fixed state of the mounting ring 15 on the fixing ring 14. At this time, the mounting ring 15 can be removed from the fixing ring 14, thereby facilitating the removal of the coil winding column 10 from the inside of the roller 9. The removed coil winding column 10 can be easily removed by the operator after the coil is wound. When using this device, it can increase the stability of the coil winding column 10 when it rotates, and also facilitate the operator to change the winding column of different shapes to wind coils of different shapes.
[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
