Description

Technical Field

[0001] This utility model relates to the field of motor stator manufacturing technology, and in particular to a winding mechanism with adjustable winding stroke. Background Technology

[0002] A coil typically refers to a toroidal winding of wire. Common examples include coils used in motors, inductors, transformers, and loop antennas. Current winding techniques mostly involve a rotary motor driving a rotating disk. One end of a connecting rod is rotatably connected to the disk, while the other end is restricted to linear movement and connected to an external guide pin. As the disk rotates, one end of the connecting rod moves in a circular motion, while the other end reciprocates, controlling the guide pin's reciprocating motion to wind the wire onto the coil frame. However, the required travel distance of the guide pin varies depending on the coil frame size. Excessive travel may cause the wire to loosen, while insufficient travel may prevent the wire from crossing the coil frame. Therefore, current techniques often require disassembly to adjust the winding travel. This involves connecting one end of the connecting rod to different positions on the rotating disk or replacing the rotating disk with a different size; the closer to the center of the rotating disk, the shorter the travel. However, this disassembly is necessary for every adjustment of the winding travel, significantly impacting efficiency. Utility Model Content

The fixed seat is disposed at the opening of the mounting hole, and the adjusting seat is located between the mounting hole and the rotating shaft. The transmission assembly includes a first internal gear ring fixedly mounted on the adjusting seat, a second internal gear ring fixedly mounted on the fixed seat, a first gear fixedly mounted on the rotating shaft, a second gear rotatably mounted on the rotating shaft, and a slider rotatably mounted on the rotating shaft. A planetary carrier, multiple first planetary gears mounted on the planetary carrier, and multiple second planetary gears mounted on the planetary carrier. A first gear is located between an adjusting seat and the planetary carrier. The planetary carrier is located between the first gear and the second gear. The end face of the planetary carrier facing the second gear is used to rotatably mount the second planetary gear. The end face of the planetary carrier facing the first gear is used to rotatably mount the first planetary gear. The first planetary gear meshes with a first internal gear ring and the first gear. The second planetary gear meshes with a second internal gear ring and the second gear. An adjusting plate is fixedly connected to the second gear. The adjusting plate has an arc-shaped groove extending from the center of the adjusting plate towards its edge. The center of a limiting plate is fixedly connected to one end of a rotating shaft. The limiting plate has a first rectangular hole. A slider is positioned along the diameter of the limiting plate, and one end of the slider movably passes through the first rectangular hole and the groove.

[0005] Furthermore, the planetary carrier has at least three mounting ends for mounting the first planetary gear and the second planetary gear, the end face of the mounting end facing the second gear being used to rotatably mount the second planetary gear, and the end face of the mounting end facing the first gear being used to rotatably mount the first planetary gear.

[0006] Furthermore, the extending direction of the first rectangular hole is parallel to the diameter of the limiting plate.

[0007] Furthermore, the winding mechanism also includes a cover plate disposed on the limiting plate. The length of the cover plate is the same as the diameter of the limiting plate. The cover plate is provided with a second rectangular hole in the same direction as the first rectangular hole. The cover plate is used to cover the edge of the slider so that the slider can slide along the second rectangular hole.

[0008] Furthermore, the adjustable winding stroke winding mechanism also includes a drive mechanism for driving the winding mechanism, and a stabilizing component disposed on the frame.

[0009] Furthermore, the drive mechanism includes a first drive wheel fixedly sleeved on the rotating shaft, a second drive gear fixedly sleeved on the adjusting seat, a first drive motor mounted on the frame, and a second drive motor mounted on the frame.

[0010] Furthermore, the first drive motor is connected to the first drive wheel and the stabilizing component via a belt, thereby driving the first drive wheel and the stabilizing component to rotate, and the output end of the second drive motor is provided with a gear that meshes with the second drive gear.

[0011] Furthermore, the stabilizing assembly includes two stabilizing shafts rotatably mounted on the frame, a plurality of eccentric blocks mounted on the stabilizing shafts, two transmission gears respectively mounted on the two stabilizing shafts, and four position support assemblies mounted on the fixed base. One end of one of the stabilizing shafts is connected to the first drive motor via a belt. The two transmission gears on the two stabilizing shafts mesh with each other. The plurality of eccentric blocks are staggered on the two stabilizing shafts and rotate together with the stabilizing shafts.

[0012] Furthermore, multiple position support components are evenly spaced on the outer side wall of the fixed base. Each position support component includes a mounting base disposed on the fixed base and a roller rotatably disposed on the mounting base. The roller is in contact with the adjustment plate.

[0013] Compared with the prior art, the adjustable winding stroke winding mechanism provided by this utility model, through the arrangement of the rotating shaft, the fixed seat, the adjusting seat, and the transmission assembly, enables simultaneous rotation of the adjusting plate and the limiting plate, or rotation of the adjusting plate alone. Synchronous rotation achieves winding motion, while the adjustment plate's individual movement adjusts the winding stroke. Specifically, the transmission assembly includes a first internal gear ring, a second internal gear ring, a first gear, a second gear, a planetary carrier, a first planetary gear, and a second planetary gear. The first gear is located between the adjusting seat and the planetary carrier, and is connected to the rotating shaft. The second gear is located between the planetary carrier and the limiting plate, and is connected to the limiting plate. The adjusting plate has an arc-shaped groove, and the limiting plate has a first rectangular hole. One end of the slider movably passes through the first rectangular hole and the groove, and the other end is used to connect to a connecting rod connected to an external guide pin. When stroke adjustment is required, the fixed rotating shaft fixes the first gear, while the rotating adjusting seat rotates to drive the first internal gear ring to rotate, causing multiple first planetary gears to revolve around the first gear. This revolve of the multiple first planetary gears causes the planet carrier and second planetary gears to rotate synchronously, driving the second gear to rotate, which in turn drives the adjusting plate to rotate. This controls one end of the slider to slide along the groove, controlling the distance from one end of the slider to the center of the limiting plate, and thus adjusting the linear distance of the other end of the slider.

[0020] The specific embodiments of this utility model are described in further detail below. It should be understood that the description of the embodiments of this utility model herein is not intended to limit the scope of protection of this utility model.

[0021] like Figures 1 to 6 The diagram shown is a structural schematic of the adjustable winding stroke winding mechanism provided by this utility model. The adjustable winding stroke winding mechanism includes a frame 10, a winding mechanism 20 mounted on the frame 10, a drive mechanism 30 for driving the winding mechanism 20, and a stabilizing component 40 mounted on the frame 10. It is conceivable that the adjustable winding stroke winding mechanism also includes other functional components, such as rotating devices, connecting components, etc., which are well-known to those skilled in the art and will not be described in detail here.

[0022] The frame 10 is provided with a mounting hole 11 for the winding mechanism 20 to pass through. The frame 10 is used to support the above-mentioned functional modules. Therefore, the frame 10 is provided with a variety of functional structures, such as screws, bolts, through holes, etc., to complete the installation and assembly of the above-mentioned functional modules. It can be set according to actual needs, and will not be described in detail here.

[0023] The winding mechanism 20 includes a rotating shaft 21 passing through the frame 10, a fixed seat 22 fixedly mounted on the frame 10, an adjusting seat 23 movably mounted on the rotating shaft 21, a transmission assembly 24 mounted on the rotating shaft 21, an adjusting plate 25 mounted on the transmission assembly 24, a limiting plate 26 mounted on the rotating shaft 21, a slider 27 slidably mounted on the limiting plate 26, and a cover plate 28 mounted on the limiting plate 26.

[0024] One end of the rotating shaft 21 is connected to the limiting plate 26, and the other end is connected to the driving mechanism 30, which drives the limiting plate 26 to rotate together.

[0025] The fixing seat 22 is disposed at the opening of the mounting hole 11. The fixing seat 22 is cylindrical and is used to accommodate the transmission assembly 24 and fix one of the internal gear rings in the transmission assembly 24. A detailed description will be given below in conjunction with the transmission assembly 24.

[0026] The adjusting seat 22 is located between the mounting hole 11 and the rotating shaft 21. One end of the adjusting seat 22 is connected to the driving mechanism 30 and is driven to rotate by the driving mechanism 30. The other end of the adjusting seat 22 is cylindrical and is used to connect to an internal gear ring in the transmission assembly 24. A detailed description will be given below in conjunction with the transmission assembly 24. In order to achieve independent rotation of the adjusting seat 22 and the rotating shaft 21, bearings or sliding sleeves or other parts are provided between the adjusting seat 22, the rotating shaft 21, and the mounting hole 11 to support their rotation.

[0027] The transmission assembly 24 includes a first internal gear ring 241 fixedly mounted on the adjusting seat 22, a second internal gear ring 242 fixedly mounted on the fixed seat 22, a first gear 243 fixedly mounted on the rotating shaft 21, a second gear 244 rotatably mounted on the rotating shaft 21, a planet carrier 245 rotatably mounted on the rotating shaft 21, a plurality of first planet gears 246 mounted on the planet carrier 245, and a plurality of second planet gears 247 mounted on the planet carrier 245.

[0028] The first gear 243 is located between the adjusting seat 22 and the planetary carrier 245. The first gear 243 is connected to the rotating shaft 21 by fasteners and rotates together with the rotating shaft 21.

[0029] The second gear 244 is located between the planetary carrier 245 and the limiting plate 25. The second gear 244 is connected to the limiting plate 25 by fasteners and rotates together with the limiting plate 25.

[0030] The planetary carrier 245 is located between the first gear 243 and the second gear 244. The planetary carrier 245 has at least three mounting ends 248 for mounting the first planetary gear 246 and the second planetary gear 247. The end face of the mounting end 248 facing the second gear 244 is used to rotatably mount the second planetary gear 247, and the end face of the mounting end 248 facing the first gear 243 is used to rotatably mount the first planetary gear 246. The first planetary gear 246 meshes with the first internal gear ring 241 and the first gear 243, and the second planetary gear 247 meshes with the second internal gear ring 242 and the second gear 244. The first and second planetary gears 246 and 247 are connected to the planetary carrier 245 by a rotating shaft passing through them, thereby rotatably mounting the first and second planetary gears 246 and 247 on the upper and lower end faces of the planetary carrier 245, respectively. The winding and adjustment methods will be explained below in conjunction with the adjustment plate 25 and the slider 27.

[0031] The adjusting plate 25 is connected to the second gear 244 by fasteners and rotates synchronously with the second gear 244. The adjusting plate 25 is provided with an arc-shaped sliding groove 251, which extends from the center of the adjusting plate 25 toward the edge of the adjusting plate 25. The sliding groove 251 is used to set one end of the slider 27 and define the sliding direction of the slider 27.

[0032] The center of the limiting plate 26 is fixedly connected to one end of the rotating shaft 21. The limiting plate 26 has a circular structure and a first rectangular hole 261 is provided on the limiting plate 26. The extending direction of the first rectangular hole 261 is parallel to the diameter of the limiting plate 26. The first rectangular hole 261 and the slide groove 251 are used to pass through the slider 27 and limit the sliding direction of the slider 27, so that it can only slide along the diameter of the limiting plate 26.

[0033] The slider 27 is elongated and is positioned along the diameter of the limiting plate 26. One end of the slider 27 movably passes through the first rectangular hole 261 and the groove 251, while the other end is used to connect to a connecting rod that connects to an external guide pin. One end of the connecting rod is rotatably connected to the slider 27, while the other end can only move linearly. When the limiting plate 26 drives the slider 27 to rotate, the slider 27 drives one end of the connecting rod to continuously rotate in a circular motion, while the other end of the connecting rod, due to its linear motion capability, continuously moves linearly, thereby driving the external guide pin to reciprocate and wind the wire. Therefore, by adjusting the position of the slider 27 and controlling the distance from one end of the slider 27 to the center of the limiting plate 26, the diameter of the circular motion of one end of the slider 27 can be controlled, thus controlling the distance of the linear motion.

[0034] The length of the cover plate 28 is the same as the diameter of the limiting plate 26, and the cover plate 28 is provided with a second rectangular hole 281 in the same direction as the first rectangular hole 261. The cover plate 28 is used to cover the edge of the slider 27, so that the slider 27 can slide along the second rectangular hole 281.

[0035] During winding, the adjusting seat 22 is fixed, thus fixing the first internal gear ring 241 as well. The rotating shaft 21 rotates, driving the first gear 243 to rotate, which in turn drives multiple first planetary gears 246 to revolve. The revolve of these planetary gears 246 causes the planet carrier 245 and the second planetary gears 247 to rotate synchronously. Since the second internal gear ring 241 is fixed to the fixing seat 22, the synchronous revolve of the second planetary gears 247 drives the second gear 244 to rotate, causing the second gear 244 and the rotating shaft 21 to rotate synchronously. This, in turn, causes the adjusting plate 25 and the limiting plate 26, which are mounted on the second gear 244 and the rotating shaft 21, to rotate synchronously, thereby driving the slider 27 to rotate.

[0036] When stroke adjustment is required, the rotating shaft 21 is fixed, thus fixing the first gear 243 as well. The adjusting seat 22 rotates to drive the first internal gear ring 241 to rotate, causing the first internal gear ring 241 to drive multiple first planetary gears 246 to revolve around the first gear 243. The revolve of the multiple first planetary gears 246 will drive the planet carrier 245 and the second planetary gears 247 to rotate synchronously. At this time, since the second internal gear ring 241 is fixed on the fixed seat 22, the synchronous revolve of the multiple second planetary gears 247 will drive the second gear 244 to rotate, causing the second gear 244 to drive the adjusting plate 25 to rotate. Since the limiting plate 26 is connected to the rotating shaft 21, when the rotating shaft 21 is fixed, only the adjusting plate 25 will rotate while the limiting plate 26 remains fixed. Therefore, the adjusting plate 25 will drive one end of the slider 27 to slide along the slide groove 251, thereby controlling the distance from one end of the slider 27 to the center of the limiting plate 26, and realizing the adjustment of the linear movement distance of the other end of the slider 27.

[0037] The drive mechanism 30 includes a first drive wheel 31 fixedly sleeved on the rotating shaft 21, a second drive gear 32 fixedly sleeved on the adjusting seat 22, a first drive motor 33 mounted on the frame 10, and a second drive motor 34 mounted on the frame 10.

[0038] The first drive motor 33 is connected to the first drive wheel 31 and the stabilizing component 40 via a belt, so that the first drive motor 33 can drive the first drive wheel 31 and the stabilizing component 40 to rotate, so that the first drive wheel 31 drives the rotating shaft 21 to rotate for winding.

[0039] The output end of the second drive motor 34 is provided with a gear that meshes with the second drive gear 32. Since the second drive gear 32 is used to adjust the adjustment seat 22, the gear control can achieve higher precision.

[0040] The stabilizing assembly 40 includes two stabilizing shafts 41 rotatably mounted on the frame 10, a plurality of eccentric blocks 42 mounted on the stabilizing shafts 41, two transmission gears 43 respectively mounted on the two stabilizing shafts 41, and four position support assemblies 44 mounted on the fixed base 22.

[0041] One end of one of the stabilizing shafts 41 is connected to the first drive motor 33 via a belt. Two transmission gears 43 on the two stabilizing shafts 41 mesh with each other, so that when one stabilizing shaft 41 rotates under the drive of the first drive motor 33, it can drive the other stabilizing shaft 41 to rotate via the transmission gears 43. Multiple eccentric blocks 42 are staggered on the two stabilizing shafts 41 and rotate with them. When rotating, the eccentric blocks generate centrifugal force, which can balance the vibration of the shaft, reduce unbalanced forces, thereby reducing vibration and noise, and improving the stability of the equipment. Multiple position support components 44 are evenly spaced on the outer wall of the fixed base 22. Each position support component 44 includes a mounting base 441 mounted on the fixed base 22 and a roller 442 rotatably mounted on the mounting base 441. The roller 442 is in contact with the adjusting plate 25, so that when the adjusting plate 25 rotates, the roller 442 can limit the position of the adjusting plate 25, preventing it from swinging back and forth during rotation and ensuring the stability of the conductor.

[0042] Compared with the prior art, the adjustable winding stroke winding mechanism provided by this utility model, through the arrangement of the rotating shaft 21, the fixed seat 22, the adjusting seat 23, and the transmission component 24, enables the simultaneous rotation of the adjusting plate 25 and the limiting plate 26, or the individual rotation of the adjusting plate 25. Synchronous rotation achieves winding motion, while individual movement of the adjusting plate 25 adjusts the winding stroke. Specifically, the transmission component 24 includes a first internal gear ring 241, a second internal gear ring 242, a first gear 243, a second gear 244, a planetary carrier 245, a first planetary gear 246, and a second planetary gear 247. The first gear 243 is located between the adjusting seat 22 and the planetary carrier 245, and is connected to the rotating shaft 21. The second gear 244 is located between the planetary carrier 245 and the limiting plate 25, and is connected to the limiting plate 25. The adjusting plate 25 has an arc-shaped groove 251, and the limiting plate 26 has a first rectangular hole 261. One end of the slider 27 is movably inserted through the first rectangular hole 261 and the groove 251, while the other end is used to connect to a connecting rod connected to an external guide pin. When the stroke needs to be adjusted, the rotating shaft 21 is fixed to fix the first gear 243, while the adjusting seat 22 rotates to drive the first internal gear ring 241 to rotate, causing multiple first planetary gears 246 to revolve around the first gear 243. The revolve of the multiple first planetary gears 246 will drive the planet carrier 245 and the second planetary gear 247 to rotate synchronously, driving the second gear 244 to rotate, which in turn drives the adjusting plate 25 to rotate. This controls one end of the slider 27 to slide along the groove 251, controls the distance from one end of the slider 27 to the center of the limiting plate 26, and thus adjusts the linear distance of the other end of the slider 27.

[0043] The above are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Any modifications, equivalent substitutions or improvements within the spirit of the present utility model are covered within the scope of the claims of the present utility model.
