[0038] The utility model provides a flat wire motor twist adjustment mechanism and a flat wire motor twist device. In order to make the purpose, technical solution and effect of the utility model clearer and more specific, the utility model is further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the protection scope of the utility model.

[0039] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0040] In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or mutual communication; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0041] At present, in the equipment for twisting multiple layers of copper wires of flat wire motors simultaneously, it is achieved by using torque output equipment. However, when multiple layers of copper wires are twisted simultaneously, the stress generated by the flat wires during the bending process may cause the position of the torque output end to shift. This shift will cause the torsion accuracy to fail to meet the requirements, thereby affecting the performance and quality of the flat wire stator and even the flat wire motor.

[0042] Please see attached Figure 1 To Attachment Figure 8 An embodiment of one aspect of the utility model discloses a flat wire motor twist adjustment mechanism, including a body 7 and a multi-layer twist mechanism, the multi-layer twist mechanism is arranged on the body 7, and each layer of the twist mechanism includes a driving mechanism, a transmission mechanism, a rotating seat 21 and an eccentric shaft seat 3.

[0043] Since each layer of the torsion mechanism is provided with a separate driving mechanism transmission, the torsion mechanism of each layer has independent driving and transmission functions, so that each layer of the torsion mechanism works independently without interfering with each other, and the torsion angle and speed of each layer of copper wire can be accurately controlled separately. For example, the torsion mechanism of each layer can be independently rotated in the forward and reverse directions according to production requirements, and the rotation angle can be adjusted, which is conducive to achieving consistency of the product after twisting, and at the same time makes the copper wire twisting production efficiency of the flat wire motor high.

[0044] The transmission mechanism includes a first transmission assembly 11 and a second transmission assembly 12. The first transmission assembly 11 is connected to the driving mechanism, and the first transmission assembly 11 and the second transmission assembly 12 are driven by gear meshing. The driving mechanism provides power to the transmission mechanism, and the transmission mechanism transmits the power to the rotating seat 21 through gear meshing transmission. The gear meshing transmission has the advantages of high transmission efficiency, accurate transmission ratio, reliable operation, etc., and can ensure the accuracy and stability of torque transmission.

[0045] Any two adjacent layers of the rotating seats 21 are nested, and each layer of the rotating seats 21 is correspondingly driven by a transmission mechanism, wherein the second transmission assembly 12 is transmission-connected with the rotating seats 21 so that the rotating seats 21 rotate around the same axis. The nested design of the rotating seats 21 makes the entire mechanism compact, and at the same time, it is also conducive to enhancing the stability and rigidity of the mechanism.

[0046] Specifically, Figure 2 and Figure 3 As shown, the diameter of the inner rotating seat 21 is smaller than that of the outer rotating seat 21, so that the rotating seats 21 are nested in layers.

[0047] The first transmission assembly 11 is disposed on the eccentric shaft seat 3, and the eccentric shaft seat 3 is configured to adjust the center distance of the gears of the meshing transmission between the first transmission assembly 11 and the second transmission assembly 12 by rotating. By rotating the eccentric shaft seat 3, the center distance of the gears of the meshing transmission between the first transmission assembly 11 and the second transmission assembly 12 can be easily adjusted. When faced with different torsion angles and speed requirements, or based on the positional deviation of the transmission structure and the rotating seat 21 caused by force problems during the twisting of the wire during the production process, the operator or other adjustment equipment can achieve precise matching by adjusting the eccentric shaft seat 3. This flexibility greatly improves the versatility and adaptability of the equipment, and can ensure that the equipment can operate stably for a long time. On the other hand, a suitable gear center distance helps to improve transmission efficiency, reduce wear and failure, and extend the service life of the equipment.

[0048] For details, please refer to the attached Figure 3 Each layer of the torsion mechanism is correspondingly provided with an eccentric shaft seat 3, the eccentric shaft seat 3 penetrates the box body and is arranged at intervals on the circumferential outer side of the rotating seat 21.

[0049] In some embodiments, the first transmission component 11 includes a first gear 111 and a transmission shaft 112, and the second transmission component 12 is provided with a second gear 121 meshing with the first gear 111 for transmission, wherein the first gear 111 is sleeved on the transmission shaft 112, and the transmission shaft 112 passes through both axial ends of the eccentric shaft seat 3, and the axis of the transmission shaft 112 deviates from the axis of the eccentric shaft seat so that the center distance between the first gear 111 and the second gear 121 can be adjusted by rotating the eccentric shaft seat.

[0050] like Figure 7As shown, the axis of the transmission shaft 112 deviates from the axis of the eccentric shaft seat 3. It can be understood that the transmission shaft 112 is not coaxial with the eccentric shaft seat, but has a certain eccentricity. Further, the first gear 111 is sleeved on the transmission shaft 112, and the transmission shaft 112 passes through the axial ends of the eccentric shaft seat 3. In this way, the transmission shaft 112 not only plays the role of transmitting power, but also can adjust the position of the transmission shaft 112 during the rotation of the eccentric shaft seat 3 to adjust the center distance between the first gear 111 and the second gear 121, thereby improving the flexibility and adaptability of the flat wire motor twist adjustment mechanism, so that it can adapt to the flat wire motor twist production with high precision requirements, and this adjustment method is simple and effective, reducing the complexity of the mechanism and manufacturing cost.

[0051] In some embodiments, the eccentric shaft seat 3 is provided with a shaft section, the shaft section is provided with a through hole 301 penetrating in the axial direction, the transmission shaft 112 is passed through the through hole 301, and the circumferential surface of the shaft section is provided with an opening 302 communicating with the through hole 301, so that the first gear 111 is meshed with the second gear 121 through the opening 302. Figure 6 and Figure 8 As shown, the shaft section of the eccentric shaft seat 3 is provided with an axis, and the axis of the transmission shaft 112 is non-coaxially arranged with the axis of the shaft section. An opening 302 connected to the through hole 301 is provided on the circumferential surface of the shaft section, so that the first gear 111 sleeved on the transmission shaft 112 can be connected to the second gear 121 on the outside through the opening 302. Moreover, the setting of the opening 302 not only provides convenience for the installation and disassembly of the gears, but also allows the meshing state between the gears to be adjusted by adjusting the eccentric shaft seat 3 when necessary.

[0052] Optionally, the shaft section is cylindrical.

[0053] For more detailed examples, please refer to the attached Figure 5 The axis of the transmission shaft 112 and the axis of the shaft section can be set to a preset eccentric distance, for example, the eccentric distance between the two is 0.5mm, and the center distance of the large and small gears can be adjusted by adjusting the installation angle of the eccentric shaft seat 3 on the body 7. In the flat wire motor twist adjustment mechanism of the present application, an adjustment scale is marked on one end of each eccentric shaft seat 3, for example, "+, -" represents the change of the center distance brought about by different rotation directions, and the adjustment range of the center distance of each group of gears is ±0.5mm.

[0054] In some embodiments, the first transmission assembly 11 further includes a first bearing 113, the inner ring of the first bearing 113 is sleeved on the transmission shaft 112, and the outer ring of the first bearing 113 is nested on the eccentric shaft seat 3. Specifically, as Figure 6 and Figure 8As shown, mounting grooves of the first bearing 113 are respectively provided at both ends of the shaft section, so that the transmission shaft 112 and the eccentric shaft seat 3 can be installed through the first bearing 113. Since the bearing has the function of reducing friction and supporting rotating parts, the transmission shaft 112 can better bear and disperse the load in the process of driving the first gear 111 and the second gear 121 to rotate, thereby improving the bearing capacity and stability of the first transmission assembly 11. The transmission shaft 112 can rotate more smoothly under the support of the first bearing 113, reducing the energy loss and performance degradation caused by friction and vibration during the transmission of the flat wire twist head, and is also conducive to reducing the error and unevenness in the copper wire twisting process, and improving the quality and consistency of the product.

[0055] In some embodiments, a plurality of support shafts 4 are further included, each layer of the rotating seat 21 is correspondingly provided with a circumferential connection portion 22, the circumferential connection portion 22 is arranged along the outer periphery of the rotating seat 21, each layer of the circumferential connection portion 22 is arranged at intervals along the axial direction of the support shaft 4, and a plurality of support shafts 4 are arranged at intervals along the circumference of the circumferential connection portion 22, the second gear 121 is connected to the circumferential connection portion 22 to drive the rotating seat 21 to rotate, and the support shaft 4 is used to limit the radial outward movement of the circumferential connection portion 22. Figure 3 As shown, the circumferential connecting portion 22 corresponding to each layer of the rotating seat 21 is arranged along the outer circumference of the rotating seat 21, and the second gear 121 is connected to the circumferential connecting portion 22, so that the driving mechanism can transmit the torque to the rotating seat 21 in sequence through the first transmission component 11, the second transmission component 12 and the circumferential connecting portion 22, and drive it to rotate. The setting of the circumferential connecting portion 22 enables the rotating seat 21 to remain stable during rotation and effectively transmit torque.

[0056] It can be understood that the circumferential spacing of multiple support shafts 4 along the circumferential connection portion 22 plays a necessary supporting role and also limits the possibility of radial outward movement of the circumferential connection portion 22. Through the constraint of the support shafts 4, the rotating seat 21 can maintain its original position and shape during the rotation process, reducing performance degradation or failure caused by deformation or displacement, and further ensuring the stable rotation of the rotating seat 21 and the uniform transmission of torque, which can reduce errors and unevenness in the torsion process of the copper wire and improve product quality and consistency.

[0057] In some embodiments, a second bearing 5 is further included. The inner ring of the second bearing 5 is sleeved on the outside of the plurality of support shafts 4 , and the outer ring of the second bearing 5 is nested in the second gear 121 . The second bearing 5 is used to radially support the second gear 121 .

[0058] As attached Figure 4As shown, the first gear 111 is located on the radial outer side of the second gear 121, and the two are meshed and driven. The second gear 121 is located on the radial outer side of the circumferential connection part 22 and drives the circumferential connection part 22 and the rotating seat 21 to rotate through the connection. By setting the inner ring of the second bearing 5 on the outer side of multiple support shafts 4 and making the outer ring of the second bearing 5 nested in the second gear 121, the radial shaking and vibration of the gear during operation can be effectively reduced. This support effect ensures the stability and reliability of the gear when transmitting torque, and improves the performance of the entire adjustment mechanism. Moreover, the inner ring of the second bearing 5 is set on the outer side of multiple support shafts 4. By adding a bearing between the support shaft 4 and the gear, the heat and energy loss generated by the friction of the second gear 121 relative to the support shaft 4 can be significantly reduced.

[0059] It is understandable that, since the bearing is a standard part, by combining the bearing with the gear, the assembly of the gear and the support shaft 4 becomes simpler and faster, while the standardization of the flat wire motor twist adjustment mechanism is improved.

[0060] In some embodiments, a plurality of fixing rings 6 are further included, and the plurality of fixing rings 6 are nested along the axial direction of the support shaft 4. The inner ring of the second bearing 5 is nested in the surface of the fixing ring 6, and the inner ring of the second bearing 5 is axially pressed between two adjacent fixing rings 6. The fixing ring 6 is used to axially support the second bearing 5. First, the fixing ring 6 is nested along the axial direction of the support shaft 4, providing additional axial support for the second bearing 5. By nesting the inner ring of the second bearing 5 in the surface of the fixing ring 6 and ensuring that the inner ring thereof is axially pressed between two adjacent fixing rings 6, the movement or shaking of the bearing in the axial direction can be effectively prevented. This stable support effect helps to improve the operating accuracy and stability of the bearing and the entire transmission system.

[0061] Secondly, the use of the fixing ring 6 also enhances the structural rigidity and load-bearing capacity between the transmission mechanism and the rotating seat 21. By introducing multiple fixing rings 6 to axially support the second bearing 5, the flat wire motor torsion adjustment mechanism further improves the stability and reliability of the equipment while maintaining efficient and precise transmission. The fixing ring 6, as a strengthening structural part, can disperse and withstand the force from the gear transmission, reduce the risk of structural damage caused by stress concentration, and improve the overall reliability and durability of the equipment.

[0062] In addition, the design of the fixing ring 6 simplifies the installation and maintenance process. The standardized and modular fixing ring 6 components can be easily assembled and disassembled, which improves work efficiency and the standardization of the flat wire motor twist adjustment mechanism.

[0063] In more detail, the surface of the fixing ring 6 is provided with a step, and another fixing ring 6 arranged adjacent to the fixing ring 6 abuts the inner ring of the second bearing 5 against the step. By providing a step on the surface of the fixing ring 6, a support point is provided for the second bearing 5, and the inner ring of the second bearing 5 abuts against the step together with the adjacent fixing ring 6, so that the inner ring of the second bearing 5 can be accurately positioned and fixed between the fixing rings 6. Moreover, through the abutment of the adjacent fixing rings 6, the stability of the inner ring of the second bearing 5 on the step can be further ensured. This support structure not only improves the bearing's load-bearing capacity, but also can prevent the bearing from falling off or shifting when subjected to external impact or vibration to a certain extent, thereby reducing the transmission error caused by the shaking or shifting of the second bearing 5.

[0064] In some embodiments, a transfer ring 122 is further included, and the transfer ring 122 is connected between the second gear 121 and the circumferential connecting portion 22. A limiting groove is formed between the transfer ring 122, the second gear 121 and the transfer ring 122, and the outer ring of the second bearing 5 is limited in the limiting groove. By connecting the transfer ring 122 between the second gear 121 and the circumferential connecting portion 22, a stable connection structure is formed, which can enhance the connection strength between the second gear 121 and the rotating seat 21, improve the rigidity and load-bearing capacity of the entire flat wire motor torsion adjustment mechanism, which is also conducive to ensuring the torque transmission accuracy.

[0065] Moreover, due to the limiting groove formed between the adapter pressure ring 122 and the second gear 121, the outer ring of the second bearing 5 can rotate with the second gear 121 in the limiting groove, ensuring the stability and reliability of the second bearing 5 during operation and preventing performance degradation or failure of the bearing due to shaking or displacement.

[0066] Optionally, the second gear 121, the adapter pressure ring 122, the circumferential connecting portion 22 and the rotating shaft are connected in an integral manner.

[0067] The two aspects of the present utility model disclose a flat wire motor twisting device, including a flat wire motor twisting adjustment mechanism and a twisting mold as in any of the above embodiments, the twisting mold is connected to the rotating seat 21 of the flat wire motor twisting adjustment mechanism, and the twisting mold is used to output torque to twist the copper wire of the stator. By applying the above flat wire motor twisting adjustment mechanism to the flat wire motor twisting device, it is possible to twist multiple layers of copper wire of the flat wire motor at the same time, the twisting angle is adjustable, and the twisting angle of each layer of copper wire is consistent, which has the advantages of strong adaptability and high production efficiency.

[0068] It is understandable that those skilled in the art can make equivalent substitutions or changes based on the technical solution and the utility model concept of the utility model, and all these changes or substitutions should fall within the protection scope of the utility model.
