A compression spring pushes the first tension wheel to rotate outward, thereby keeping the copper wire taut and facilitating its tight winding onto the stator frame. However, when the copper wire is about to be wound, the compression spring causes the tension wheel to pull the copper wire, resulting in the copper wire losing tension and affecting the alignment of the copper wire with the insertion groove.

[0023] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. This utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] Reference Figures 1-4 This utility model provides a tension adjustment mechanism for a segmented stator winding machine, including a mounting base 1. Multiple first guide wheels 2 are rotatably mounted on one side of the mounting base 1. An adjustment component for tensioning copper wire is provided on one side of the mounting base 1. A one-way locking frame 3 is fixed to one side of the mounting base 1 by bolts, and the wire passes through the one-way locking frame 3. A rubber ring 6 is provided inside the one-way locking frame 3, and the wire passes through the middle of the rubber ring 6. The one-way locking frame 3 includes a movable part 303 for the rubber ring 6 to move. The side of the movable part 303 near the first guide wheels 2 is a locking part 301, and the other side of the movable part 303 is a blocking part 302. The locking part 301 has a conical structure, and the blocking part 302 has a planar structure.

[0025] In use, the wire is passed through the multiple first guide wheels 2 and through the one-way locking bracket 3 and the rubber ring 6;

[0026] When the conductor is wound, the stator will pull the conductor to move, thereby moving the conductor from the locking part 301 to the blocking part 302, which in turn drives the rubber ring 6 to move. The blocking part 302 will block the rubber ring 6 to prevent the rubber ring 6 from leaving the moving part 303, while the rubber ring 6 will not restrict the movement of the conductor.

[0027] When the conductor is being prepared for winding, the adjusting component pulls the conductor to move in the opposite direction, which in turn causes the conductor to move the rubber ring 6 in the opposite direction. This allows the rubber ring 6 to enter the locking part 301. The conical locking part 301 will compress and deform the rubber ring 6. The inner wall of the deformed rubber ring 6 will tightly adhere to the surface of the conductor. The high frictional properties of the rubber material will effectively clamp the conductor and prevent it from moving in the opposite direction. This achieves a one-way locking function, preventing the conductor from loosening or springing back due to the pulling force of the adjusting component during the winding preparation stage. This ensures that the conductor always maintains a stable initial tension state, laying the foundation for precise tension control in the subsequent winding process.

[0028] The adjustment component, by pulling the wire in the opposite direction, in conjunction with the synergistic effect of the conical locking part 301 of the one-way locking frame 3 and the rubber ring 6, forms a dynamic tension balance mechanism.

[0029] When the conductor moves forward due to winding requirements, the rubber ring 6 is in a relaxed state under the limit of the blocking part 302, and will not generate additional resistance to the normal feed of the conductor; when the conductor position needs to be adjusted in the reverse direction during the winding preparation stage, the rubber ring 6 is squeezed into the locking part 301, and the friction between its inner wall and the surface of the conductor increases instantly, quickly locking the reverse displacement of the conductor, avoiding the problem of winding disorder or wire diameter stretching deformation caused by unstable tension of the conductor.

[0030] This design not only simplifies the complex structure of traditional tension adjustment mechanisms, but also achieves adaptive locking of wires with different diameters through the elastic deformation characteristics of the rubber ring 6, enhancing the versatility and practicality of the mechanism and effectively reducing the difficulty of equipment debugging and maintenance.

[0031] In this utility model, the adjustment component includes a rotating frame 4 that rotates on one side of the mounting base 1. One end of the rotating frame 4 is rotatably connected to a second guide wheel 5. An adjustment frame 8 is rotatably connected to one side of the mounting base 1. A tension spring 7 is provided between the adjustment frame 8 and the rotating frame 4 to pull the rotating frame 4 to rotate. The tension spring 7 is detachable and easy to replace. The other end of the adjustment frame 8 is provided with a limiting component to fix the angle of the adjustment frame 8.

[0032] The rotating frame 4 can rotate freely around the axis of the mounting base 1. The second guide wheel 5 guides the direction of the wire. The adjusting frame 8 is the core component for adjusting the attitude of the rotating frame 4. The tension spring 7 between the adjusting frame 8 and the rotating frame 4 can provide continuous tension, causing the rotating frame 4 to maintain a specific tilt angle.

[0033] When it is necessary to adjust the initial tension of the wire, the operator can change the tension of the tension spring 7 by rotating the adjustment frame 8, thereby adjusting the magnitude of the reverse tension of the rotating frame 4 on the wire: the greater the tension of the tension spring 7, the stronger the reverse force of the rotating frame 4 on the wire, and with the locking effect of the one-way locking frame 3, the initial tension maintained by the wire is also increased accordingly; conversely, reducing the tension of the tension spring 7 can reduce the initial tension of the wire, achieving flexible adaptation to different winding process requirements;

[0034] Once the angle of the adjusting frame 8 is determined, the limiting component locks its position to prevent the adjusting frame 8 from shifting due to vibration or external interference during the winding process, ensuring that the tension of the tension spring 7 remains stable, thereby maintaining the continuous and reliable operation of the entire tension balance system.

[0035] Furthermore, the limiting component includes a through hole opened at one end of the adjusting frame 8, a rod 10 inserted into the through hole, a plurality of holes 9 opened on one side of the mounting base 1, and one end of the rod 10 inserted into the hole 9. A pulling component is provided on one side of the adjusting frame 8 to drive the rod 10 to move toward the hole 9.

[0036] When the angle of the adjusting frame 8 needs to be adjusted, the operator pulls the insert rod 10 outward to disengage it from the current insertion hole 9. At this point, the adjusting frame 8 can be freely rotated to the target angle. Then, the insert rod 10 is pushed into the corresponding insertion hole 9 to complete the quick locking of the adjusting frame 8 by the limiting component. The entire operation does not require any additional tools. The insertion holes 9 are evenly distributed in the circumferential direction of the mounting base 1. The angular interval between adjacent insertion holes 9 can be designed according to the actual adjustment accuracy requirements to ensure that the adjusting frame 8 can achieve multi-level adjustment within the preset angle range, further improving the accuracy and convenience of tension adjustment.

[0037] Furthermore, the pulling component includes a first magnetic block 11 and a second magnetic block 12. The first magnetic block 11 and the second magnetic block 12 are respectively bonded to one side of the adjustment frame 8 and the insertion rod 10. The opposing surfaces of the first magnetic block 11 and the second magnetic block 12 are opposite magnetic poles. In a natural state, the magnetic attraction between the two will keep the insertion rod 10 inserted into the insertion hole 9, effectively preventing the insertion rod 10 from accidentally coming off and causing the adjustment frame 8 to loosen.

[0038] When it is necessary to pull the plug rod 10, the operator only needs to overcome the magnetic attraction to pull the plug rod 10 outward. The operation is labor-saving and the response is quick. After the adjustment is completed, the plug rod 10 is released, and the magnetic attraction will automatically pull the plug rod 10 back and insert it into the corresponding socket 9. This further simplifies the locking operation steps and improves the stability and ease of use of the overall structure.

[0039] The working principle of this utility model:

[0040] In use, the wire is passed between multiple first guide wheels 2 and second guide wheels 5, and then through the one-way locking frame 3 and the rubber ring 6 to achieve the transfer of the wire;

[0041] When the conductor is wound, the stator will pull the conductor to move, thereby moving the conductor from the locking part 301 to the blocking part 302, which in turn drives the rubber ring 6 to move. The blocking part 302 will block the rubber ring 6 to prevent the rubber ring 6 from leaving the moving part 303, while the rubber ring 6 will not restrict the movement of the conductor.

[0042] During the winding preparation, the tension spring 7 pulls the rotating frame 4 to rotate, thereby pulling the wire to move in the opposite direction. This causes the wire to move the rubber ring 6 in the opposite direction, allowing the rubber ring 6 to enter the locking part 301. The conical locking part 301 will compress and deform the rubber ring 6. The inner wall of the deformed rubber ring 6 will tightly adhere to the surface of the wire, using the high frictional properties of the rubber material to effectively clamp the wire and prevent the wire from continuing to move in the opposite direction. This achieves a one-way locking function, preventing the wire from loosening or springing back due to the tension of the adjustment component during the winding preparation stage. This ensures that the wire always maintains a stable initial tension state, laying the foundation for precise tension control during the subsequent winding process.
