[0027] Flat wire winding is a winding method in the field of motor manufacturing, which improves the power density and efficiency of the motor by using flat wires. However, during the manufacturing process of flat wire winding, especially during the slotting process, the problem of flat wire deformation often occurs.

[0028] Flat wire winding into slot refers to the process of inserting the flat wire winding formed by winding the flat wire into the slot of the motor stator during the motor manufacturing process. This step is a key link of motor winding assembly, and the purpose is to fix the winding on the stator so that the motor can work normally. Since the flat wire has higher rigidity due to its flat shape, the winding with multiple flat wires needs to be inserted into the stator slot as a whole to realize the assembly during the winding into slot process. The flat wire on the winding is prone to deformation, which not only increases the difficulty of the winding into slot assembly, but also may affect the performance of the motor, resulting in insulation damage, poor contact and thermal management problems.

[0029] To solve the above problems, please refer to Figures 1 to 4 The utility model provides a kind of into slot follow-up tool 1000, including hoop 1 and compression ring 2 connected with each other, the aperture of the middle hole of compression ring 2 is greater than the aperture of the middle hole of hoop 1, the inner peripheral wall of hoop 1 is used to hoop flat wire winding, and compression ring 2 is formed with multiple positioning holes 221 for the outgoing end of flat wire winding to pass through, and each positioning hole 221 is distributed at the inner periphery of compression ring 2.

[0030] The technical scheme of the utility model provides a kind of into slot follow-up tool 1000, and the tool includes hoop 1 and compression ring 2 connected with each other, and both are annular structure. The inner peripheral wall of hoop 1 is used to hoop flat wire winding, to reduce the deformation of flat wire winding when inserting into slot, and the aperture of the central hole of compression ring 2 is greater than the aperture of the central hole of hoop 1, so as to facilitate the pressure of flat wire winding by compression ring 2, and flat wire is inserted into stator slot, and multiple positioning holes 221 are distributed at cover body, to facilitate outgoing wire on flat wire winding to pass through to avoid deformation of outgoing wire in the process of pressing down. The accuracy and reliability of flat wire winding into slot installation are improved. Through this design, the error in installation process can be reduced, production efficiency is improved, and due to accurate positioning, vibration and noise in motor operation can be reduced, so as to improve the performance of motor.

[0031] In an optional embodiment, please refer to Figures 1 to 4, the hoop ring 1 and the compression ring 2 are integrated. This integrated design simplifies the number of components of the slot-entry follower tool 1000, reduces assembly complexity, and can improve the stability and durability of the overall structure. The integrated hoop ring 1 and compression ring 2 are easier to form during manufacturing, thereby improving production efficiency. In addition, the integrated structure reduces errors caused by the combination of multiple independent components, thereby improving the accuracy and consistency of the slot-entry follower tool 1000. This design also helps to enhance the mechanical strength of the slot-entry follower tool 1000, enabling it to withstand greater forces without deformation or damage. In actual operation, the integrated structure simplifies the operation steps, reduces assembly time, reduces production costs, and reduces the complexity of maintenance and replacement of the slot-entry follower tool 1000 due to the reduction in the number of components.

[0032] In an optional embodiment, the compression ring 2 includes a first sector 21 and a second sector 22, the first sector 21 and the second sector 22 are spliced to form the compression ring 2, the cross section of the first sector 21 is a rectangular structure, and the second sector 22 is a stepped structure. The first sector 21 is a rectangular structure in cross section, and the second sector 22 is a stepped structure. This design provides different functional and strength requirements for different parts of the compression ring 2, where the first sector 21 can provide primary structural strength so that the compression ring 2 can have higher strength to extend the service life of the slot-entry follower tool 1000 as much as possible. The second sector 22 allows more flexibility or adaptability. Since the flat wire winding is provided with a bend at the position of the lead-out wire, the second sector 22 of the stepped structure can better adapt to different winding shapes, thereby improving the versatility and applicability of the slot-entry follower tool 1000. The design of this structure allows the slot-entry follower tool 1000 to maintain structural strength while also being able to adapt to different installation environments and requirements, increasing the flexibility and scope of application of the slot-entry follower tool 1000.

[0033] Specifically, the thickness of the first sector 21 is greater than the thickness of the second sector 22. The first sector 21 as the main structural support, its greater thickness helps to ensure the stability and durability of the compression ring 2 during use, and can ensure sufficient stability when the compression ring 2 is compressed during the installation of the flat wire winding into the slot, and also helps to disperse and absorb stress generated during assembly and use, reducing the risk of damage due to stress concentration. Ensuring normal slot-entry installation and improving the service life of the slot-entry follower tool 1000.

[0034] In an optional embodiment, to facilitate the passage of the lead-out wires through the positioning holes 221, the positioning holes 221 comprise a straight section and a tapered section, which are sequentially arranged and transitionally connected in the direction close to the hoop 1, and the hole diameter of the tapered section gradually increases in the direction away from the straight section. This design helps to realize the cooperation of the positioning holes 221 with the lead-out wires on the flat wire winding, improving the convenience of assembly. The straight section is used to ensure the stability and strength of the positioning holes 221, while the tapered section provides the functions of guidance and progressive cooperation, making it easier for the lead-out wires to be inserted into the positioning holes 221. This helps to simplify the assembly process and improve the positioning accuracy. This design enables the slotting follow-up tool 1000 to be more accurately positioned when assembling with the flat wire winding, reducing errors caused by inaccurate positioning, and improving the efficiency and quality of assembly. In addition, the design of the tapered section also helps to reduce friction during installation, making assembly smoother, and also provides convenience for disassembly. In this embodiment, the number of positioning holes 221 is 6, and each positioning hole 221 is distributed on the inner edge of the pressure ring 2. When assembling the slotting, the flat wire winding is first assembled with the slotting follow-up tool 1000, and the lead-out wires on the flat wire winding are inserted one by one through the positioning holes 221, avoiding deformation of the lead-out wires during subsequent pressing. By limiting the radial and axial directions of the flat wire winding through the slotting follow-up tool 1000, the deformation caused by slotting is reduced or avoided, improving the convenience and accuracy of the flat wire winding slotting.

[0035] In an optional embodiment, the positioning holes 221 are waist-shaped holes. The design of the waist-shaped holes provides better positioning accuracy and stability, helping to reduce stress concentration around the positioning holes 221, thereby improving the overall strength and durability of the tool. In addition, the unique shape of the waist-shaped holes also helps to improve the recognizability of the tool, making it easier for operators to identify and align the positioning holes 221, reducing errors and time consumption during assembly. In other embodiments, the shape of the positioning holes 221 can also be circular or trapezoidal, etc., which can be selected according to actual needs.

[0036] In an optional embodiment, to further improve the strength of the slotting follow-up tool 1000, please refer to Figures 1 to 4The slotting pilot tool 1000 further includes a wear ring 3 connected to the compression ring 2 at an end distal from the collar ring 1, with the wear ring 3 having a central bore of equal diameter to that of the compression ring 2. The use of the wear ring 3 aims to improve the wear resistance of the tool, particularly in contact or friction areas, helping to extend the service life of the slotting pilot tool 1000, reduce maintenance needs, and maintain the performance stability of the slotting pilot tool 1000. It also helps to reduce wear under high load or frequent use conditions, thereby improving the reliability and economy of the slotting pilot tool 1000. The addition of the wear ring 3 can also reduce the loss of precision due to wear, ensuring that the slotting pilot tool 1000 can maintain its initial performance after long-term use.

[0037] Further, the compression ring 2 is formed with a mounting groove 2a, and the wear ring 3 is clamped in the mounting groove 2a, with the compression ring 2 flush with the top of the wear ring 3. This mounting method provides a simple and effective fixing method, ensuring the stability and consistency of the wear ring 3 in position. The flush design helps the slotting pilot tool 1000 to maintain uniform compression when under pressure, thereby ensuring the stability of the flat wire winding slot installation. In addition, the flush design can also keep the appearance of the slotting pilot tool 1000 neat and tidy, and reduce potential problems caused by height differences, such as scratching or interference. In addition, this mounting method can simplify the manufacturing and assembly process, improving production efficiency. The flush design can also help reduce material usage, thereby reducing costs, and due to the reduction in the number of components, it also reduces the complexity of maintenance and replacement.

[0038] In an optional embodiment, the wear ring 3 is fixed to the compression ring 2 by screwing. The use of screw connection provides a reliable and detachable connection method, which helps to simplify the repair and replacement process. Screw connection allows the slotting pilot tool 1000 to be easily disassembled and reassembled when needed, which is very useful for maintaining and upgrading the slotting pilot tool 1000. In addition, screw connection provides the possibility of adjustment and fine-tuning to adapt to different applications or compensate for wear. It improves the stability and reliability of the slotting pilot tool 1000, as it can provide uniform stress distribution, reducing the risk of damage due to improper connection.

[0039] In an optional embodiment, the material of the compression ring 2 and the hoop ring 1 is POM plastic, and the material of the wear-resistant ring 3 is stainless steel. POM plastic has high strength, wear resistance, and excellent mechanical properties, which make it an ideal material for manufacturing the compression ring 2 and the hoop ring 1. The stainless steel wear-resistant ring 3 provides additional durability and corrosion resistance, especially in applications that require high load bearing or harsh environmental conditions. This combination of materials may be designed to combine the advantages of both materials to achieve optimal performance and durability, while maintaining the lightweight and cost-effectiveness of the in-slot follow-up tool 1000. The use of POM plastic helps to improve the impact resistance and chemical resistance of the in-slot follow-up tool 1000, while the stainless steel wear-resistant ring 3 helps to improve the wear resistance and high-temperature resistance of the tool, which are essential for ensuring the performance of the tool in various working environments.
