[0048] Please refer to Figures 2-4 Stroke device 2 includes stroke seat 21, and the top of stroke seat 21 is close to the fixed mounting of connecting back plate 22 in end position, and telescopic machine 3 output shaft is connected with connecting back plate 22, and the top of stroke seat 21 is fixedly installed with rotating motor 23 through the rib plate in the position above connecting back plate 22, and the one end of rotating motor 23 output shaft is fixedly installed with rotating device 24, and the inside of rotating device 24 is movably sleeved with fixed shaft device 25, and the inside of fixed shaft device 25 is movably installed with clamping device 26 by telescopic cooperation.

[0049] Please refer to Figure 3 And Figures 5-6 Rotating device 24 includes rotating shaft sleeve 241, and the top of rotating shaft sleeve 241 outer surface is close to the fixed mounting of winding arm 242 in front end position, and the front end of winding arm 242 is fixedly installed with first wire wheel 243, and first wire wheel 243 is connected with enameled wire winding, and the inside of rotating shaft sleeve 241 inner wall is close to the setting of cooperation groove in front and back end position, and the both sides of rotating shaft sleeve 241 inner wall are close to the setting of limit sliding slot 244 in intermediate position, and the bottom of rotating shaft sleeve 241 inner wall is close to the setting of through -hole in intermediate position, and the outside of rotating shaft sleeve 241 outer surface is movably sleeved with tension supplement device 27 through connecting plate in the position corresponding with the through -hole, and the both sides of rotating shaft sleeve 241 outer surface are fixedly installed with wire guide seat 245.

[0050] Winding arm 242 and tension supplement device 27 adopt the arrangement of upside -down symmetry, which makes the centrifugal force that winding arm 242 and tension supplement device 27 receive in the process of rotating reach balance, avoids the device in the process of winding to iron core 11 and winding frame 13, can substantially reduce the vibration amplitude in the process of high rotating of rotating shaft sleeve 241, improves its stability in the process of winding operation.

[0051] Please refer to Figure 2 And Figures 7-8The fixed shaft sleeve 251 is provided with bearings on the outer surface near the front end and the rear end, and the bearings correspond to the matching grooves on the inner wall of the rotating shaft sleeve 241. A strip-shaped sliding hole 252 is formed on the outer surface of the fixed shaft sleeve 251 near the middle, and the strip-shaped sliding hole 252 is in sliding cooperation with the clamping device 26. An extension stopper 253 is fixedly installed at one end of the inner cavity of the fixed shaft sleeve 251.

[0052] Please refer to Figure 1 and Figures 7-10 The clamping device 26 comprises a connecting rod 261, and a clamping block 262 is fixedly installed at the front end of the connecting rod 261. The front end arc surface of the clamping block 262 is matched with the coil holder 13 to realize clamping. An annular ball rack 263 is fixedly installed on the outer surface of the connecting rod 261 and cooperates with the strip-shaped sliding hole 252. An annular synchronous rack 264 is movably sleeved on the back of the annular ball rack 263 through ball cooperation. Limiting sliding blocks 265 are arranged on the outer surface of the annular synchronous rack 264, and the limiting sliding blocks 265 cooperate with the limiting sliding grooves 244. An adjusting tooth rod 266 is fixedly installed on the back of the annular synchronous rack 264 near the bottom.

[0053] When the clamping block 262 clamps the iron core 11, the output shaft of the extension stopper 253 will extend and abut against the tail end of the connecting rod 261. At this time, the connecting rod 261 cannot move, avoiding the tension supplementing device 27 rotating and driving the adjusting tooth rod 266 to move under the action of centrifugal force, causing the displacement of the annular ball rack 263 and the loosening of the clamping of the clamping block 262 on the iron core 11, thereby improving the stability of the device during operation.

[0054] Please refer to Figure 6 and Figures 10-12 The tension supplementing device 27 comprises a rotating frame 271, and an adjusting gear 272 is fixedly installed at one end of the rotating frame 271. The adjusting gear 272 is in meshing cooperation with the adjusting tooth rod 266, and the adjusting gear 272 is movably sleeved with the bottom connecting plate of the rotating shaft sleeve 241. A partition plate 273 is arranged on the inner side of the rotating frame 271 near the adjusting gear 272. A sliding groove is arranged on the inner side of the rotating frame 271, and a second wire wheel 274 is movably installed in the sliding groove through cooperation. A balance spring 275 is arranged on the back side of the second wire wheel 274, and one end of the balance spring 275 is connected with the partition plate 273.

[0055] When the device is winding, the rotation speed of the rotating shaft sleeve 241 will be sharply increased, which causes the traction of the enameled wire to be suddenly increased, so that the enameled wire is straightened instantaneously, which makes the elastic tension device used to increase the tension of the enameled wire jump up, so that the enameled wire and the elastic tension device are out of contact, which makes the enameled wire lose the effect of tension limitation in a short time during the winding operation, resulting in the decrease of the winding quality of the enameled wire. In the present application, when the rotation speed of the rotating shaft sleeve 241 is sharply increased, the second wire wheel 274 in the tension supplement device 27 moves away from the baffle 273 under the action of centrifugal force. Since the enameled wire is wound outside the second wire wheel 274 at this time, the movement of the second wire wheel 274 will increase the tension received by the enameled wire. When the elastic tension device loses the effect of tension limitation on the enameled wire, the second wire wheel 274 can supplement the tension of the enameled wire and limit it, so as to ensure that the tension received by the enameled wire when it is wound outside the winding frame 13 by the device is within a reasonable range, and to ensure that the motor rotor after winding meets the quality requirements, thereby improving the practicability of the device.

[0056] When the rotation speed of the rotating shaft sleeve 241 is stable, the centrifugal force received by the second wire wheel 274 and the elastic force of the balance spring 275 are in a parallel state. At this time, the second wire wheel 274 stops moving and loses the effect of tension on the enameled wire. At the same time, the elastic tension device resets and comes into contact with the enameled wire and continues to apply tension to the enameled wire. This avoids the simultaneous application of tension to the enameled wire by the second wire wheel 274 and the elastic tension device, which may cause damage to the enameled wire, thereby improving the reliability of the device during operation.

[0057] When the radius of the iron core 11 used is large, the movement distance of the connecting rod 261 into the fixed shaft sleeve 251 increases when the clamping block 262 clamps the iron core 11. At the same time, the annular ball holder 263 pushes the ring-shaped synchronous frame 264 to move synchronously. By adjusting the meshing effect of the toothed rod 266 and the adjusting gear 272, the rotating frame 271 is driven to rotate, so that the included angle between the tension supplement device 27 and the rotating device 24 increases, and the distance between the second wire wheel 274 and the axis of the rotating device 24 increases. After the rotation speed of the rotating shaft sleeve 241 is sharply increased, the centrifugal force generated by the second wire wheel 274 increases. Since the radius of the iron core 11 is large, the length of the enameled wire consumed by the rotating shaft sleeve 241 per revolution increases, and the demand for tension of the enameled wire increases. Since the displacement distance of the second wire wheel 274 increases and the pulling force on the enameled wire increases under the premise of increasing centrifugal force, the tension of the enameled wire is increased. Thus, when the radius of the iron core 11 is increased and the elastic tension device loses the effect of tension limitation on the enameled wire, the tension supplement effect of the second wire wheel 274 on the enameled wire is simultaneously increased. The device can automatically adjust the tension supplement effect of the second wire wheel 274 on the enameled wire according to the radius of the iron core 11, thereby improving the practicability of the device.

[0058] The method of use of the present application is as follows:

[0059] In use, after the enameled wire is wound around the outer surface of the second wire wheel 274, it is passed through the wire seat 245 and wound around the outer surface of the first wire wheel 243. The connecting shaft 12 is then fixed to the fixed rotating machine 4. The extension machine in the fixed rotating machine 4 pushes the connecting shaft 12 to the position corresponding to the clamping block 262. The control extension machine 3 pushes the stroke device 2 to move towards the iron core 11. Finally, the clamping block 262 is in contact with the iron core 11 and clamped. After the clamping block 262 and the iron core 11 are clamped, the output shaft of the extension and resistance rod 253 extends and abuts against the end of the connecting rod 261.

[0060] When the device is winding, the rotation speed of the rotation sleeve 241 will be sharply increased, which leads to the sudden increase of the traction force of the enameled wire, so that the enameled wire is straightened instantaneously, which makes the elastic tension device used to increase the tension of the enameled wire jump up, so that the enameled wire and the elastic tension device are out of contact, which makes the enameled wire lose the effect of tension limitation in a short time during the winding operation, resulting in the decrease of the winding quality of the enameled wire. In the present application, when the rotation speed of the rotation sleeve 241 is sharply increased, the second wire wheel 274 in the tension supplement device 27 moves away from the baffle 273 under the action of centrifugal force. Since the enameled wire is wound outside the second wire wheel 274 at this time, the movement of the second wire wheel 274 will increase the received tension of the enameled wire, so that the second wire wheel 274 can supplement the tension of the enameled wire and limit it when the elastic tension device loses the effect of tension limitation on the enameled wire, ensuring that the tension received by the device when winding the enameled wire outside the winding frame 13 is within a reasonable range. When the rotation speed of the rotation sleeve 241 is stable, the centrifugal force received by the second wire wheel 274 and the elastic force of the balance spring 275 are in a parallel state, at which time the second wire wheel 274 stops moving and loses the effect of tension on the enameled wire. At the same time, the elastic tension device resets and contacts the enameled wire and continues to apply tension to the enameled wire. When the radius of the used iron core 11 is large, the movement distance of the connecting rod 261 to the inside of the fixed sleeve 251 increases when the clamping block 262 clamps the iron core 11. At the same time, the annular ball holder 263 pushes the ring-shaped synchronous frame 264 to move synchronously. By adjusting the meshing effect of the tooth rod 266 and the adjusting gear 272, the rotating frame 271 is driven to rotate, so that the included angle between the tension supplement device 27 and the rotating device 24 increases, and the distance between the second wire wheel 274 and the axis of the rotating device 24 increases. After the rotation speed of the rotation sleeve 241 is sharply increased, the centrifugal force generated by the second wire wheel 274 increases. Since the radius of the iron core 11 is large, the length of the enameled wire consumed by the rotation of the rotation sleeve 241 increases, and the demand for tension of the enameled wire increases. Since the displacement distance of the second wire wheel 274 increases and the tension of the enameled wire increases under the premise of increasing the centrifugal force, the tension supplement effect of the second wire wheel 274 on the enameled wire is improved, so that the device can automatically adjust the tension supplement effect of the second wire wheel 274 on the enameled wire according to the radius of the iron core 11.
