[0003] The prior art patent application (application number 202021270553.6) entitled "Coil Winding Auxiliary Device" includes a bracket, a torque controller, a support shaft, and a locking mechanism.

The coil winding auxiliary device provided herein uses a locking mechanism to fix the coil roll to the support shaft, and the support shaft is connected to the output shaft of the torque controller.

[0004] Existing coil winding auxiliary devices use a fixed transmission ratio structure or a single gear adjustment mode, which lacks the adaptability to quickly adjust the coil winding speed. They are not convenient for dynamically adjusting the winding speed according to process parameters such as the wire diameter, number of turns, and winding density of the coil winding. Therefore, a new technical solution needs to be designed to solve this problem. Summary of the Invention

[0005] The purpose of this invention is to provide an adjustable speed coil winding device to solve the above-mentioned problems, thereby addressing the lack of adaptability in the prior art to quickly adjust the coil winding speed and the inconvenience of dynamically adjusting the winding speed according to process parameters such as the wire diameter, number of turns, and winding density of the coil winding.

[0010] Preferably, a gear driven rod is rotatably connected to one side of the mounting frame. The gear driven rod meshes with the multi-stage drive gear. The other end of the gear driven rod passes through the mounting frame and is fixedly connected to the rotating seat on one side.

[0012] Preferably, a limiting sleeve is fixedly connected to one side of the support frame. The limiting sleeve is located outside the rotating rod.

[0018] This utility model provides an adjustable speed coil winding device.

[0019] Example 1, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 The device includes a mounting frame 1, with rotating seats 101 rotatably connected to the two inner walls of the mounting frame 1. A wire roller 102 is screwed between the inner sides of the two rotating seats 101. A driven gear 2 is rotatably connected to one side of the mounting frame 1. A mounting rod 201 is fixedly connected to one side of the driven gear 2. A cross mounting plate 202 is fixedly connected to one end of the mounting rod 201.

[0020] Please refer to it again. Figure 1 , Figure 2 and Figure 3 Four multi-stage drive gears 3 are rotatably connected to one side of the cross mounting plate 202. A hexagonal mating seat 301 is fixedly connected to one side of the multi-stage drive gears 3. An adjustable fixing frame 4 is fixedly connected to one side of the mounting frame 1. A motor 401 is fixedly connected to one side of the adjustable fixing frame 4. A hexagonal drive rod 402 is fixedly connected to one end of the power output shaft of the motor 401. One end of the hexagonal drive rod 402 passes through the adjustable fixing frame 4 and is inserted into the hexagonal mating seat 301. A gear driven rod 5 is rotatably connected to one side of the mounting frame 1. The gear driven rod 5 meshes with the multi-stage drive gears 3. The other end of the gear driven rod 5 passes through the mounting frame 1 and is fixedly connected to a rotating seat 101 on one side.

[0021] The multi-stage adjustable winding speed mechanism uses a motor 401 as its power source. An adjustable mounting bracket 4 ensures stable installation of the motor 401 and the hexagonal drive rod 402. After the motor 401 starts, its power output shaft drives the hexagonal drive rod 402 to rotate synchronously. The hexagonal drive rod 402, through its engagement with the hexagonal mating seat 301, transmits power to the multi-stage drive gears 3 on the cross mounting plate 202. The cross mounting plate 202 provides evenly distributed mounting bases for the four multi-stage drive gears 3, each corresponding to a different transmission ratio. By switching the engagement of the hexagonal drive rod 402 with different hexagonal mating seats 301 of the multi-stage drive gears 3, different transmission ratios can be selected. The driven rod 5, meshing with the selected multi-stage drive gear 3, receives power and transmits torque to the rotating seat 101 fixedly connected to it. This drives the wire roller 102, screwed between the two rotating seats 101, to rotate synchronously, ultimately achieving multi-level adjustment of the winding speed of the wire roller 102 to meet the coil winding requirements of different processes.

[0022] Example 2, please refer to again. Figure 1 , Figure 2 and Figure 4A support frame 6 is fixedly connected to one side of the mounting frame 1. A rotating rod 601 is rotatably connected to one side of the support frame 6. One end of the rotating rod 601 passes through the support frame 6 and extends to the other side of the support frame 6. A transmission gear 602 is fixedly connected to one end of the rotating rod 601. The transmission gear 602 is rotatably connected to the mounting frame 1 and meshes with the driven gear 2. A limiting sleeve 7 is fixedly connected to one side of the support frame 6. The limiting sleeve 7 is located outside the rotating rod 601. Two limiting slots 701 are provided on the outer side of the limiting sleeve 7. A pressure plate 8 is slidably connected to the inner cavity of the rotating rod 601. A square rod 801 is fixedly connected to one side of the pressure plate 8. A return spring 802 is sleeved on the outer side of the square rod 801. One end of the square rod 801 passes through the rotating rod 601 and is compressed to the outer side of the rotating rod 601. A lifting seat 9 is fixedly connected to one end of the square rod 801. Two locking rods 901 are fixedly connected to the outer side of the lifting seat 9. The locking rods 901 are engaged with the limiting slots 701.

[0023] The locking mechanism of the transmission gear 602 uses the support frame 6 as the mounting carrier. The rotating rod 601 is rotatably supported by the support frame 6. The transmission gear 602, fixed at one end, meshes with the driven gear 2 to transmit power and adjust the winding speed. The limiting sleeve 7 is fixed to the support frame 6 and sleeved on the outside of the rotating rod 601. The two limiting slots 701 on the sleeve provide positioning stops for the rotating rod 601. The pressure plate 8, which is slidably connected to the inner cavity of the rotating rod 601, always applies a pushing force towards the lifting seat 9 under the elastic force of the return spring 802. This causes the two locking rods 901 on the outside of the lifting seat 9 to tightly engage with the limiting slots 701 of the limiting sleeve 7, thereby locking the rotating rod 601 and fixing the meshing position of the transmission gear 602 and the driven gear 2 to ensure a stable transmission ratio. When it is necessary to switch gears, pull up the lifting seat 9. The square rod 801 drives the pressure plate 8 to compress the return spring 802, causing the locking rod 901 to disengage from the limit slot 701. At this time, the rotating rod 601 can be rotated to adjust the angle of the transmission gear 602. After adjusting to the target gear, release the lifting seat 9. The return spring 802 resets and pushes the pressure plate 8 and the square rod 801, causing the locking rod 901 to re-engage into the corresponding limit slot 701, completing the re-locking of the transmission gear 602 and ensuring the stability of the transmission structure after speed adjustment.

[0024] Working Principle: The device uses the mounting frame 1 as its core mounting base. The wire roller 102 is screwed to the inside of the mounting frame 1 via two rotating seats 101, achieving stable assembly of the winding carrier. The power transmission and speed regulation system consists of a multi-stage adjustable winding speed mechanism and a locking mechanism for the transmission gear 602. The motor 401 is fixedly mounted via an adjustable mounting bracket 4. Its power output shaft drives the hexagonal drive rod 402 to rotate. The hexagonal drive rod 402 can be switched with the hexagonal mating seats 301 of different multi-stage drive gears 3 on the cross mounting plate 202 to select the corresponding transmission ratio. The cross mounting plate 202 is fixedly connected to the driven gear 2 via the mounting rod 201. The driven gear 2 meshes with the transmission gear 602. After selecting the target multi-stage drive gear 3, the power is transmitted to the rotating seat 101 via the gear driven rod 5, driving the wire roller 102 to rotate at a uniform speed to complete the winding operation. The locking mechanism of the transmission gear 602 ensures speed regulation stability: the rotating rod 601 is rotatably supported by the support frame 6, and the transmission gear 602 at one end meshes with the driven gear 2. The limiting sleeve 7 is sleeved on the outside of the rotating rod 601. The return spring 802 pushes the lifting seat 9 through the pressure plate 8 and the square rod 801, so that the locking rod 901 is tightly engaged with the limiting slot 701 of the limiting sleeve 7, locking the position of the rotating rod 601 and the transmission gear 602 to ensure a constant transmission ratio. When it is necessary to switch the winding speed, the lifting seat 9 is pulled to drive the locking rod 901 out of the limiting slot 701. The rotating rod 601 is rotated to adjust the angle of the transmission gear 602, which simultaneously drives the driven gear 2 and the cross mounting plate 202 to rotate, so that the hexagonal drive rod 402 is aligned and inserted with the hexagonal docking seat 301 of another multi-stage drive gear 3. After the lifting seat 9 is released, the locking rod 901 is reset and locked, completing the gear switching. Through the linkage of the above mechanisms, the winding speed can be precisely adjusted in multiple levels and the winding speed can be uniformly adjusted to meet different process requirements.
