Description

Technical Field

[0001] The utility model relates to the technical field of transverse flux motor windings, in particular to a winding tool for transverse flux motor windings. Background Art

[0002] The transverse flux motor breaks the inertial structure of the traditional motor, innovates the two-dimensional distribution in the traditional magnetic circuit, and has higher torque density and electromagnetic decoupling. The characteristic of the transverse flux permanent magnet motor is that it can obtain high torque density, but at the same time there are many problems that need further study. One of the main problems of the transverse flux permanent magnet motor is that the winding forming and manufacturing process has become the difficulty and focus of the research and development of the transverse flux permanent magnet motor. The winding method of the stator three-phase winding and the winding manufacturing process are relatively difficult. At present, there are not many good processes that can ensure the forming arrangement of the stator winding. Unlike the traditional radial flux motor, the magnetic field direction of the stator winding of the transverse flux motor is transverse, which means that the winding must be arranged in three dimensions in space. Such a three-dimensional structure requires precise winding path and spatial position to ensure the optimization of electromagnetic performance. This arrangement usually includes toroidal windings, laminated windings or complex geometric shapes to adapt to the magnetic circuit design. The winding structure of the transverse flux motor may require a multi-level arrangement, each layer of windings needs to be arranged on a different plane, and there needs to be precise spacing and insulation between layers. Such a multi-layer structure increases the difficulty of winding the winding, because it is necessary to ensure that the winding position of each layer is accurate and there is no electrical short circuit with other layers. In short, the complex structure of the transverse flux motor winding is mainly reflected in the three-dimensional arrangement, multi-layer structure, complex path and other aspects. Each aspect requires high-precision design and manufacturing process to ensure the high performance and reliability of the transverse flux motor. Utility Model Content

[0003] Technical problems to be solved by utility models

[0004] In response to the technical problems of large deviation, low efficiency and low yield of existing winding technology, the utility model provides a winding tool for transverse flux motor windings, which can achieve precise arrangement of multi-layer complex structures of transverse flux motors, reduce winding deviation, and improve winding efficiency and yield.

[0005] Technical Solution

[0006] In order to solve the above problems, the technical solution provided by the utility model is:

[0007] A winding tool for a transverse flux motor winding comprises a base; a winding shaft rotatably connected to the base; a winding seat fixedly connected to the end of the winding shaft, the circumference of the winding seat being provided with a groove for clamping the winding wire; a tooling strip, which is arc-shaped, and whose end face cooperates with the groove for pressing the wound winding wire, and whose outer arc surface cooperates with the unwound winding wire, and which comprises several specifications with different outer diameters; an auxiliary sheet, which cooperates with the outer arc surface of the tooling strip for pressing in the winding wire.

[0008] Base: Serves as the foundation of the entire device and provides stable support.

[0009] Winding shaft: mounted on the base through bearings or similar mechanisms, can rotate freely to facilitate winding operations.

[0010] Winding seat: fixed at one end of the winding shaft, with grooves on its circumference. These grooves are used to position and guide the winding to ensure the correct arrangement of the winding.

[0011] Tooling bar: It is designed in an arc shape with different outer diameters to meet the needs of winding wires of different sizes. The end face of the tooling bar cooperates with the groove on the winding seat to fix the already wound wire, while its outer arc surface contacts the wire to be wound, helping to guide and support the wire, ensuring the tension and position control during the winding process.

[0012] Auxiliary sheet: used in conjunction with the outer arc surface of the tooling strip to further enhance the suppression and guidance of the winding, which helps to arrange the winding more tightly and accurately.

[0013] Optionally, a pulley block is further included, wherein the pulley block is provided with a plurality of pulleys for tensioning the winding, and the pulleys are arranged in a staggered manner.

[0014] Tension control: By adjusting the position and angle of the pulley, the path of the winding can be changed, thereby controlling the tension of the winding during the winding process. This is very important to ensure the tightness and consistency of the winding, because proper tension can prevent the winding from loosening during the winding process, resulting in an unstable winding structure.

[0015] Guiding function: The pulley can guide the winding wire to move along the predetermined path, ensuring that the winding wire enters the groove of the winding seat accurately and passes smoothly between the tooling strip and the auxiliary sheet. This helps the winding wire maintain linearity during the winding process, prevents the winding wire from unnecessary bending or twisting in complex structures, and thus improves the quality of the winding.

[0016] Reduce wear: The pulley surface is usually smooth, which can reduce the friction between the winding and the tooling, avoid damaging the insulation layer of the winding during the winding process, and ensure the electrical performance of the winding.

[0017] Adjustability: The design of the pulley block allows the operator to adjust the position of each pulley as needed to adapt to different sizes and types of windings, as well as different winding structure requirements, increasing the flexibility and applicability of the tooling.

[0018] Optionally, the tooling strip of a single specification includes a half-moon strip and a half-moon piece with the same curvature, and the half-moon piece is arranged on the outer arc surface of the half-moon strip, and the thickness of the half-moon piece is the thickness of a single-layer winding.

[0019] The combination of the half-moon sheet and the half-moon strip allows the winding process to accurately control the position and pressure of each layer of winding, which is especially important for multi-layer windings. By replacing half-moon sheets of different thicknesses, it is possible to adapt to windings of different diameters and achieve precise superposition of multi-layer windings, thereby constructing a complex transverse flux motor winding structure. When using it, the half-moon strip can be left unremoved. After only removing the half-moon sheet, the outer diameter of the half-moon strip can be reduced by one specification, and the next circle of winding can be carried out directly, which improves the winding efficiency.

[0020] As an option, the largest tooling strips are available in round shape.

[0021] The outermost layer of winding can form a complete circle, and there is no need to consider the reduction of the diameter in the first circle.

[0022] As an option, except for the largest size of the half-moon strip which is semicircular, the half-moon piece is 1 / 4 circle.

[0023] The semicircular half-moon strips and 1 / 4-circular half-moon pieces are designed to facilitate disassembly, so that the wire can be wound circle by circle from the outside to the inside.

[0024] Optionally, the auxiliary sheet is elastic.

[0025] Adaptive pressure: The elastic auxiliary sheet can automatically adjust the applied pressure according to the diameter of the winding and the shape of the winding, ensuring that the winding is evenly and moderately compressed during the winding process. This helps maintain the stability of the winding and the tightness of the winding, while avoiding deformation or damage of the winding due to excessive pressure.

[0026] Reduce stress concentration: When the elastic auxiliary sheet contacts the winding, it can disperse the stress at the contact point to avoid damage to the winding caused by excessive local stress, especially at the corners of the winding or the edge area of ​​the winding.

[0027] Optionally, the thicknesses of the tooling strips of several specifications with different outer diameters decrease in units of winding thickness.

[0028] Adapt to multi-layer windings: As the number of winding layers increases, the total thickness of the winding gradually accumulates. The thickness of the tooling strip decreases in units of the winding thickness, which means that each layer of winding has a tooling strip of corresponding thickness to adapt to it. This can ensure that each layer of winding can be properly supported and positioned during the winding process, avoiding winding deflection or looseness caused by the mismatch between the tooling strip and the winding thickness.

[0029] Precise control of winding dimensions: Tooling bars of different specifications can precisely control the position and spacing of each layer of winding, thereby ensuring the accuracy and consistency of the overall winding dimensions. This is particularly important for motor designs that require strict control of geometric parameters, such as transverse flux motors, where the accuracy of the winding structure directly affects the performance and efficiency of the motor.

[0030] Optionally, the tooling strip is made of plastic.

[0031] The plastic material is relatively light, making the tooling strips easy to handle and operate, reducing the workload of operators, especially when the tooling strip specifications need to be changed frequently. The plastic produces less wear when in contact with the winding, which helps to protect the insulation layer of the winding from damage and maintain the electrical performance of the winding.

[0032] Beneficial Effects

[0033] Compared with the prior art, the technical solution provided by the utility model has the following beneficial effects:

[0034] The technical solution provided by the utility model is provided with a tooling strip, which is designed in an arc shape and has different outer diameter specifications to meet the requirements of windings of different sizes. The end face of the tooling strip cooperates with the groove on the winding seat to fix the already wound winding, while its outer arc surface contacts the winding to be wound, helping to guide and support the winding, ensuring the tension and position control during the winding process. The precise arrangement of the multi-layer complex structure of the transverse flux motor is achieved, the deviation of the winding is reduced, and the winding efficiency and yield rate are improved.

[0039] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings and embodiments.

[0040] Example

[0041] Combined with Figure 1 , a winding tool for a transverse flux motor winding, including a base 1, which is made of metal and serves as the foundation of the entire device to provide stable support. A winding shaft 2 is rotatably connected to the base 1 and is installed on the base 1 through a bearing. It can rotate freely to facilitate the winding 8 operation. A winding seat 3 is fixed to the end of the winding shaft 2. The circumference of the winding seat 3 is provided with a groove for engaging the winding 8. The groove is used to position and guide the winding 8 to ensure the correct arrangement of the winding. The grooves are distributed along the circumference of the circular winding seat 3, and the winding 8 is embedded in the grooves to achieve the positioning of the winding 8. It also includes a pulley block 7, and the pulley block 7 is provided with a plurality of pulleys for tensioning the winding 8, and the pulleys are staggered.

[0042] Combined with Figure 2 The tooling strip 4 is arc-shaped, and its end surface cooperates with the groove to press the wound winding 8, and its outer arc surface cooperates with the unwound winding 8, which includes several specifications with different outer diameters.

[0043] The tooling strip 4 of a single specification includes a half-moon strip 401 and a half-moon piece 402 with the same curvature. The half-moon piece 402 is arranged on the outer arc surface of the half-moon strip 401 , and the thickness of the half-moon piece 402 is the thickness of a single-layer winding 8 .

[0044] In this embodiment, eight sizes of tooling strips 4 are designed, and the largest size No. 8 tooling strip 4 is circular. Except for the largest size, the other half-moon strips 401 are semicircular, and the half-moon pieces 402 are 1 / 4 circular.

[0045] The auxiliary sheet 5 cooperates with the outer arc surface of the tooling strip 4 to press the winding wire 8 into the groove. The thickness of the tooling strips 4 of different outer diameters is reduced in units of the thickness of the winding wire 8. The auxiliary sheet 5 is elastic. The tooling strip 4 is made of plastic.

[0046] Combined with Figure 3, the winding 8 is a two-layer flat wire, which is wound in a double helix model. The first layer is wound from the inside to the outside, specifically starting from the front end of the winding and winding outward in circles. The second layer is wound from the winding transition line, which is the outermost circle in the local diagram (the number of circles is related to the electromagnetic performance). The second layer is wound from the outside to the inside until it is wound to the end of the winding. According to this method, the two output wires of one item of the motor are on the inside of the coil, which is convenient for outputting the wires from the inner diameter of the stator. In addition, it is constrained that the number of layers along the axial direction must be an even number. Similarly, multiple layers are arranged in the above manner. In this embodiment, the winding is six layers in the axial direction, and the number of circles wound on the same layer is eight circles. The first, third, and fifth layers are automatically wound by the machine from the inside to the outside. The second, fourth, and sixth layers are wound using this tooling, from the outside to the inside. Specifically, the winding principle is as follows:

[0047] Use it in turn around the second, fourth, and sixth layers;

[0048] Finish the first circle of the No. 8 tooling strip 4 around the outside, fix it with glue and then remove it;

[0049] Put in the No. 7 tooling strip 4 (to support the first circle), use the No. 6 tooling strip 4 and the auxiliary sheet 5 to wind the second circle, remove the No. 7 tooling strip 4 after winding half a circle, and then put in another No. 6 tooling strip 4 and the auxiliary sheet 5 to complete the second circle, and fix it with glue;

[0050] For the third circle, take off a half circle of the No. 6 tooling strip 4 and replace it with the No. 5 tooling strip 4. After winding half a circle, take off another No. 6 tooling strip 4 and replace it with the second No. 5 tooling strip 4 and the auxiliary sheet 5 to complete the third circle of winding, and fix it with glue. And so on, keep winding inward until the last circle is completed, and then use the machine to wind the third layer.

[0051] The above schematically describes the present invention and its implementation methods, which are not restrictive. The drawings show only one implementation method of the present invention, and the actual structure is not limited thereto. Therefore, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the present invention, they should all fall within the protection scope of the present invention.
