Description

Technical Field

[0001] This utility model relates to the field of motor manufacturing technology, and in particular to a winding mold for motor stator winding. Background Technology

[0002] In motor manufacturing, to ensure the wound coil can be smoothly embedded into the stator slot and has a suitable end, a winding mold needs to be designed according to the stator dimensions. During the winding process, the winding mold supports and guides the enameled wire of the stator coil, ensuring the wire is neatly and tightly arranged, avoiding crossing, knotting, or damage and peeling, thus improving winding quality. Chinese patent application number 2023103756679 discloses an adjustable motor coil winding mold and winding module assembly. This winding mold is an older model, which is difficult to process, has high manufacturing costs, long delivery times, and limited adaptability to stator coils. Utility Model Content

[0003] The purpose of this invention is to provide a winding mold for motor stator windings to solve the problems encountered in the background art.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows: A winding mold for a motor stator winding includes at least one set of tooling components. Each set of tooling components includes a back plate and a flat plate. The flat plate is detachably connected to the back plate. The outer periphery of the flat plate is provided with a winding surface. A wire insertion groove is provided on one side of the back plate. Insertion holes are provided in the middle of the back plate and the middle of the flat plate. The insertion holes are any one of rectangular holes, polygonal holes, and irregular holes.

[0005] In the above solution, slots are provided on both sides of the back plate. The positions of the slots on each side are different, and the slots and the cable insertion slots are located on different sides. The depth of the slots is smaller than the depth of the cable insertion slots, and the cable insertion slots are inclined on the back plate.

[0006] In the above solution, screw holes are evenly distributed along the center line of the plate. The plate is detachably connected to the back plate by screws screwed into these screw holes. The plate has a split structure, comprising a first plate and a second plate, which have the same structure. The inner sides of the first plate and the second plate evenly divide the insertion hole.

[0007] Furthermore, the back plate is a rectangular structure, and the flat plate is also a rectangular structure, but it can also be designed into other structures.

[0008] Compared with the prior art, the beneficial effects of this utility model are: the new detachable winding mold has a simple overall structure, lower cost, and simpler processing steps in the preparation of enameled wire. The back plate can be reused and is suitable for various stator sizes. Different stators only need to be replaced with a plate of the corresponding size according to the winding needs. The plate is locked with screws, which is simple and easy to operate. Attached Figure Description

[0011] To make the technical means, creative features, achieved objectives and effects of this utility model easier to understand, the utility model will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of this utility model, and therefore only show the relevant components of this utility model.

[0012] Based on the technical solution of this utility model, without changing the essential spirit of this utility model, those skilled in the art can propose various interchangeable structural methods and implementation methods. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model, and should not be regarded as the entirety of this utility model or as a limitation or restriction of the technical solution of this utility model.

[0013] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0014] Example 1, such as Figure 1 As shown, a winding mold for a motor stator winding includes at least one set of tooling components, each set of tooling components including a back plate 1 and a flat plate 2. In actual use, multiple sets of tooling components need to be connected in series and inserted into the manufacturing platform of the motor stator winding, waiting to be embedded in the stator slots to provide raw material supply for the enameled wire of the stator winding.

[0015] Unlike traditional winding molds, in this design, the flat plate 2 is detachably connected to the back plate 1. This detachable structure facilitates the replacement of different models of flat plates 2, and allows for the sharing of the same back plate 1. The outer periphery of the flat plate 2 has a winding surface 21, on which the enameled wire is wound laterally. The back plate 1 provides support for the enameled wire. When two or more sets of tooling components are used, the enameled wire is wound on the winding surface 21, with both sides restricted by the back plate 1, thus enabling unidirectional winding. The wound enameled wire is arranged clockwise or counterclockwise, preventing overlap or crushing damage.

[0016] A wire insertion slot 11 is provided on one side of the back plate 1. After a sufficient number of turns of coil are wound, the end of the enameled wire can be inserted into the wire insertion slot 11 as the finished product after winding, awaiting subsequent production of motor windings by automated equipment. Insertion holes 3 are provided in the middle of both the back plate 1 and the middle of the flat plate 2. The insertion holes 3 can be any of rectangular, polygonal, or irregularly shaped holes. The insertion holes 3 allow insertion into a wire feeding tool for motor winding production. This tool, driven by a motor rotation, rotates the tooling assembly, thereby releasing the enameled wire to provide raw materials for the motor windings.

[0017] The back plate 1 has slots 12 on both sides, with the slots 12 positioned differently on each side, and the slots 12 and the wire insertion slots 11 are located on different sides. The slots 12 are designed to hold the back plate 1, tooling components, or the entire winding mold in place on the workbench when not in use, facilitating easy access. The depth of the slots 12 is less than the depth of the wire insertion slots 11. The wire insertion slots 11 are angled on the back plate 1, allowing the enameled wire to be temporarily secured in the slots 11 according to the winding direction after winding, preventing the coil from loosening.

[0018] Example 2, based on the solution of Example 1, please refer to... Figure 1 and Figure 3 Screw holes 22 are evenly distributed along the center line of the middle section of the plate 2. The plate 2 is detachably connected to the back plate 1 by screwing screws 23 into the screw holes 22. According to the design, each plate 2 has at least 3 sets of screw holes 22 symmetrically arranged on its upper and lower sides. During installation, only any two screws 23 are needed to fix the plate 2 to the back plate 1.

[0019] Example 3, based on the solution of Example 2, please refer to... Figure 2The plate 2 has a split structure, comprising a first plate 24 and a second plate 25. The first plate 24 and the second plate 25 have the same structure and are symmetrical during installation. The inner sides of the first plate 24 and the second plate 25 divide the insertion hole 3 equally. When the first plate 24 and the second plate 25 are combined, a complete insertion hole 3 can be assembled. When the first plate 24 and the second plate 25 are separated, the shape of the insertion hole 3 in the middle is also separated. However, this does not affect normal insertion because the insertion hole 3 on the back plate 1 is complete and has a polygonal structure that can be positioned and inserted into the insertion rod of the workbench.

[0020] In implementation, both the back plate 1 and the flat plate 2 are rectangular, a simple structure that facilitates manufacturing. Alternatively, an arc-shaped or semi-circular structure can be chosen, as long as it achieves symmetry and facilitates winding. Furthermore, the tooling components are made of PA66 nylon, which has significantly higher mechanical strength and hardness than PU material, making it suitable as an engineering plastic and resulting in a much longer lifespan for the new winding mold compared to the older model.

[0021] Through the solutions in Examples 1-3, the new detachable winding mold has a simple overall structure, lower cost, and simpler processing steps in the preparation of enameled wire. The back plate 1 is reusable and suitable for various stator sizes. Different stators only need to be replaced with a plate 2 of the corresponding size according to the winding requirements. The plate 2 is locked with screws, which is simple and easy to operate.
