Description

Technical Field

[0001] This application relates to the field of split stator coil winding technology for electric motors, and in particular to a split stator magnetic pole coil winding fixture. Background Technology

[0002] Currently, the winding process of motor stator magnetic pole coils plays an important role in motor manufacturing, especially the winding technology of split stator magnetic pole coils.

[0003] Existing winding techniques for split stator magnetic pole coils typically involve individually winding the same-pole split iron cores of the split stator magnetic pole coil. After winding the coils of the same-pole split iron cores, the coils of the two split iron cores need to be welded together. During the wire connection process, the coils of the split iron cores are connected by welding, resulting in many solder joints.

[0004] However, in the above-mentioned prior art, there are problems such as poor soldering, broken soldering, or improper connection at the parallel connection of the two separate iron core coils, which can lead to the breakage of the solder joint and the failure of the separate stator magnetic pole coil due to inadequate insulation. Summary of the Invention

[0005] To address the issues that individual winding of the same-pole split core of a split stator magnetic pole coil increases the number of solder joints, and that poor soldering, broken soldering, or improper connection can occur at the parallel connection of two split core coils, leading to solder joint breakage and inadequate insulation, thus causing the split stator magnetic pole coil to fail, this application provides a split stator magnetic pole coil winding fixture.

[0006] This application provides a split-type stator magnetic pole coil winding fixture, which adopts the following technical solution: A split-type stator magnetic pole coil winding fixture includes a support base and a transmission mechanism for winding rotation. A transmission shaft is mounted on the support base, with one end connected to the transmission mechanism and the other end connected to a connecting block. The connecting block has an L-shaped connector with perpendicular ends. Both ends of the connector have clamping blocks for holding split-type stator cores of the same magnetic pole, and each clamping block has a slot adapted to the shape of the split-type stator core. The clamping block also has a fixing component for securing the split-type stator core. The connecting block has a driving component for continuously switching the windings of two same-pole split-type stator cores on the connector, with the output end of the driving component connected to the connector.

[0007] By adopting the above technical solution, two separate magnetic pole cores are simultaneously mounted on a winding fixture. The transmission mechanism drives the two separate magnetic pole cores to rotate simultaneously via a transmission shaft, causing one of the two separate magnetic pole cores to rotate and wind. After winding one magnetic pole, a sufficiently long bridge wire is reserved as needed, and then the other end of the connector at a 90-degree angle is rotated to the winding position by the driving component to perform winding. This enables the separate magnetic pole cores to be processed without interruption of wire, achieving integrated winding of two separate magnetic pole cores. This reduces the number of wires connected to the separate magnetic pole cores, thereby reducing the number of solder joints, lowering the failure rate, and increasing reliability.

[0008] Preferably, the connection between the clamping block and the connector is a detachable connection, and both ends of the connector are connected to the center of the clamping block.

[0009] By adopting the above technical solution, the clamping block and the connecting piece are detachable, allowing the clamping block to be replaced when damaged without disassembling the whole unit, thus facilitating maintenance and improving maintenance efficiency. At the same time, by connecting the two ends of the connecting piece to the center of the clamping block, the clamping block is subjected to balanced force, ensuring that the iron core rotates symmetrically and stably during the winding process, guaranteeing the concentricity and uniformity of the coil winding, and improving the quality of the winding.

[0010] Preferably, the connection between the connecting block and the drive shaft is a detachable connection, and the centerline of the drive shaft coincides with the centerline of the connecting piece.

[0011] By adopting the above technical solution, the detachable design of the connecting block and the drive shaft allows the connecting parts and clamping components to be quickly disassembled and replaced as a whole. This facilitates switching between different specifications of winding components according to production needs, or performing individual maintenance and debugging of the connecting parts, enhancing the flexibility of tooling combinations. The centerline of the drive shaft coincides with the centerline of the connecting parts, ensuring that the entire winding assembly rotates around the same axis, avoiding centrifugal force and vibration caused by eccentricity, improving the stability of the winding process, ensuring that the coil is accurately positioned on the iron core and has a uniform number of turns, and reducing winding errors caused by eccentricity.

[0012] Preferably, bearings are symmetrically arranged on the surface of the drive shaft, and the outer surface of the bearings is connected to the inner wall of the support base.

[0013] By adopting the above technical solution and providing radial support at two points on the bearing, the rigidity and stability of the drive shaft are greatly increased, allowing it to rotate only around its own axis, thus suppressing all other unnecessary movements to the greatest extent, reducing wear between the drive shaft and the support seat, and extending the service life of the drive shaft.

[0014] Preferably, the transmission mechanism includes a rotating disk, a pneumatic telescopic component, a support frame, and a drive motor. One end of the rotating disk near the transmission shaft is connected to the transmission shaft. One end of the pneumatic telescopic component is connected to the rotating disk, and the other end of the pneumatic telescopic component is connected to the output end of the drive motor. The drive motor is mounted on the support frame, and the support frame is connected to a support base.

[0015] By adopting the above technical solution, the pneumatic telescopic component is driven by the drive motor to rotate, which in turn drives the rotating disk to rotate. The rotating disk then drives the transmission shaft to rotate, which in turn drives the split stator core on the clamping block to rotate and wind the coil. This allows the drive motor to provide stable rotational power. By connecting the pneumatic telescopic component and the rotating disk, the speed and rotation angle of the transmission shaft can be precisely controlled, ensuring the consistency of the number of coil turns and the arrangement density during the winding process, thus meeting the requirements for high-precision winding.

[0016] Preferably, the rotating disk and the pneumatic telescopic component are detachably connected, and a handle is detachably connected to the rotating disk.

[0017] By adopting the above technical solution, if the pneumatic telescopic component or drive motor is damaged, it can be quickly removed from the "rotary plate" for replacement without disassembling the entire tooling, which greatly shortens maintenance time and downtime losses. At the same time, when the power source fails, the production line does not have to stop completely. The operator can immediately switch to manual mode and use the handle to continue to complete the production task or carry out emergency handling, ensuring the flexibility and continuity of production.

[0018] Preferably, the support base is provided with a plurality of mounting holes for mounting the support base, and the mounting holes are symmetrically distributed on the support base.

[0019] By adopting the above technical solution, multiple mounting holes provide a larger total clamping force and more connection points. When the tooling rotates at high speed or starts and stops suddenly, the symmetrically distributed design can evenly distribute the generated vibration and counter-torque to the entire bottom surface of the support base and then transmit it to the worktable, effectively preventing the tooling from loosening, shaking or "creeping" during operation, and providing a solid foundation for high-precision winding.

[0020] In summary, this application includes at least one of the following beneficial technical effects: 1. By simultaneously mounting two separate magnetic pole cores onto a winding fixture, the transmission mechanism drives the two separate magnetic pole cores to rotate simultaneously via a transmission shaft, causing one of the two separate magnetic pole cores to rotate and wind. After winding one magnetic pole, and reserving a sufficiently long bridge wire as needed, the other end of the connector at an angle is rotated to the winding position via a drive component to perform winding. This enables continuous winding of the separate magnetic pole cores, reduces the number of parallel wires on the two separate magnetic pole cores, thereby reducing the number of solder joints, lowering the failure rate, and increasing reliability. 2. By aligning the centerline of the drive shaft with the centerline of the connector, it can be ensured that the entire winding assembly rotates around the same axis, avoiding centrifugal force and vibration caused by eccentricity, improving the stability of the winding process, ensuring that the coil is accurately positioned on the iron core and has a uniform number of turns, and reducing winding errors caused by eccentricity; 3. If the pneumatic telescopic component or drive motor is damaged, it can be quickly removed from the "rotary plate" for replacement without disassembling the entire tooling, which greatly shortens maintenance time and downtime losses. At the same time, when the power source fails, the production line does not have to stop completely. The operator can immediately switch to manual mode and use the handle to continue to complete the production task or carry out emergency handling, ensuring the flexibility and continuity of production.

[0023] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 This application will be described in further detail.

[0024] This application discloses a split-type stator magnetic pole coil winding fixture.

[0025] Reference Figure 1 and Figure 2A split-type stator magnetic pole coil winding fixture includes a support base 1, a transmission mechanism 2, and a transmission shaft 3. The surface of the transmission shaft 3 is rotatably connected to the inner wall of the support base 1. One end of the transmission shaft 3 is connected to the transmission mechanism 2, which drives the transmission shaft 3 to rotate, thus winding the split-type stator core. The transmission mechanism 2 is mounted on the support base 1. The other end of the transmission shaft 3 is fixedly connected to a connecting block 4 by bolts. A connecting member 5 is movably connected to the middle part of the connecting block 4. The connecting member 5 is L-shaped with both ends perpendicular. Clamping blocks 6 are fixedly connected to each other by bolts. Clamping blocks 6 are used to clamp the split stator cores of the same magnetic pole. The clamping blocks 6 have slots 7 that are adapted to the shape of the split cores. The clamping blocks 6 are threadedly connected to the top of the clamping blocks 6. The fixing parts 8 are used to fix the split stator cores on the clamping blocks 6. At the same time, the top of the connecting block 4 is fixedly connected to the driving part 9. The driving part 9 is a pneumatic switcher. The driving part 9 is used to switch the winding of the two split cores of the same pole without interruption. The output end of the driving part 9 is connected to the connecting part 5. By simultaneously mounting two separate stator cores onto the winding fixture, the transmission mechanism 2 drives the two separate stator cores to rotate simultaneously via the transmission shaft 3, causing one of the two separate stator cores to rotate and wind. After winding one magnetic pole, and reserving a sufficiently long bridge wire as needed, the other end of the connector 5, which is at a 90-degree angle, is rotated to the winding position via the drive component 9 for winding. This enables continuous winding of the separate stator cores, avoiding the cumulative errors caused by multiple clamping during traditional "single winding". It ensures higher consistency in the number of turns and tightness of the double coil winding, reduces the number of parallel wires between the two separate stator cores, reduces the number of weld points generated by parallel wires, thereby reducing the welding failure rate and increasing the reliability of the separate stator cores.

[0026] refer to Figure 2 and Figure 3 The connection between the clamping block 6 and the connecting piece 5 is detachable, and both ends of the connecting piece 5 are connected to the center of the clamping block 6. By making the clamping block 6 and the connecting piece 5 detachable, the clamping block 6 can be replaced when damaged without disassembling the whole, which facilitates maintenance and improves maintenance efficiency. At the same time, connecting both ends of the connecting piece 5 to the center of the clamping block 6 ensures that the clamping block 6 is subjected to balanced force, so that the iron core always rotates symmetrically and stably during the winding process, ensuring the concentricity and uniformity of the coil winding and improving the quality of winding.

[0027] The transmission mechanism 2 includes a rotating disk 21, a pneumatic telescopic component 22, a support frame 23, and a drive motor 24. The rotating disk 21 is fixedly connected to the transmission shaft 3 on the side closest to it, and the center of the rotating disk 21 is aligned with the centerline of the transmission shaft 3. The side of the rotating disk 21 furthest from the transmission shaft 3 is detachably connected to the pneumatic telescopic component 22. The other end of the pneumatic telescopic component 22 is connected to the output end of the drive motor 24. The drive motor 24 is fixed to the support frame 23, and the end of the support frame 23 closest to the support base 1 is fixedly connected to the support base 1. A handle 25 is threaded onto the rotating disk 21, allowing for detachment. The drive motor 24 drives the pneumatic telescopic component 22 to rotate, which in turn drives the rotating disk 21 to rotate, which in turn drives the transmission mechanism 24. The rotation of shaft 3 causes the transmission shaft 3 to drive the split stator core on clamping block 6 to rotate and wind the wire. This allows drive motor 24 to provide stable rotational power. The transmission shaft 3 can be precisely controlled in terms of speed and rotation angle through pneumatic telescopic component 22 and rotating disk 21. This ensures the consistency of the number of coil turns and arrangement density during the winding process, meeting the requirements for high-precision winding. In case of damage to pneumatic telescopic component 22 or drive motor 24, they can be quickly removed from rotating disk 21 for replacement without disassembling the entire tooling, significantly reducing maintenance time and downtime losses. Furthermore, when the power source fails, the production line does not have to be completely stopped. The operator can immediately switch to manual mode and use handle 25 to continue production tasks or perform emergency handling, ensuring the flexibility and continuity of production.

[0028] refer to Figure 3 and Figure 4 The connection between the connecting block 4 and the drive shaft 3 is detachable. The connecting block 4 and the drive shaft 3 are fixed by bolts, and the center line of the connecting block 4 coincides with the center line of the drive shaft 3. By making the clamping block 6 and the connecting piece 5 detachable, the clamping block 6 can be replaced when damaged without disassembling the whole, which facilitates maintenance and improves maintenance efficiency. At the same time, by connecting the two ends of the connecting piece 5 to the center position of the clamping block 6, the clamping block 6 can be subjected to balanced force, so that the iron core always rotates symmetrically and stably during the winding process, ensuring the concentricity and uniformity of the coil winding and improving the quality of winding.

[0029] refer to Figure 4 and Figure 5 Bearings 10 are symmetrically arranged on the surface of the drive shaft 3. The surface of the drive shaft 3 is fixedly connected to the inner ring of the bearing 10, and the outer ring of the bearing 10 is fixedly connected to the inner wall of the support seat 1. By providing radial support at two points of the bearing 10, the rigidity and stability of the drive shaft 3 are greatly increased, so that it can only rotate around its own axis, while suppressing all other unnecessary movements to the greatest extent, reducing the wear between the drive shaft 3 and the support seat 1, and extending the service life of the drive shaft 3.

[0030] The implementation principle of this application embodiment is as follows: In implementation, two separate stator cores of the same pole are simultaneously clamped into the slots 7 on the two clamping blocks 6 on the connector 5. Then, the fixing member 8 is rotated to fix the separate stator cores. After fixing, the separate stator core at one end of the connector 5 is placed in the winding area, so that the copper wire is fixed on the separate stator core. Then, the drive motor 24 is started, and the drive motor 24 drives the pneumatic telescopic member 22 to rotate. The pneumatic telescopic member 22 drives the rotating disk 21 to rotate. The rotating disk 21 drives the transmission shaft 3 to rotate. The transmission shaft 3 drives the connecting block 4 to rotate. The connecting block 4 drives the connecting member 5 to rotate. The clamping block 6 rotates, causing the split stator core on the clamping block 6 to rotate as well, winding one of the split stator cores. After winding is completed, the drive motor 24 stops, and the drive component 9 works. The drive component 9 drives the connecting component 5 to switch, so that the other split stator core is located in the winding area, and the copper wire is stretched and located on the split stator core. The drive motor 24 works again, so that the switched split stator core is wound. After winding is completed, the two same-pole split stator cores are disassembled, so that the winding between the two split stator cores does not need to be cut, avoiding welding or connection, and improving the production quality of the motor. In practice, when the drive motor 24 is damaged or loses power, the pneumatic telescopic component 22 is rotated to detach from the rotating disk 21. Then, the handle 25 is connected to the rotating disk 21, and the rotating disk 21 is manually rotated by the handle 25, which drives the transmission shaft 3 to rotate, so that the equipment continues to work and the production line does not have to stop completely. The handle 25 can continue to complete the production task or perform emergency handling, ensuring the flexibility and continuity of production.

[0031] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
