Description

Technical Field

[0001] This utility model belongs to the field of coil winding technology, and specifically relates to a coil winding device. Background Technology

[0002] In the motor manufacturing industry, motors using concentric winding schemes require winding coils of different sizes. For example, the first coil has an outer diameter of 14.9mm, requiring four positioning pieces to form a square before winding. The second coil has an outer diameter of 26.7mm, requiring another four positioning pieces to form a square before winding, and so on. Each size of coil requires four positioning pieces. A motor often has multiple sizes of coils, thus requiring a large number of positioning pieces. Traditional winding dies stack each set of positioning pieces sequentially, forming a tower-like aluminum stack structure. These winding dies are heavy and bulky, sometimes weighing tens of kilograms, making them inconvenient to use.

[0003] Furthermore, the cost of manufacturing winding dies is high, which increases manufacturing costs if the required quantity of a certain size of coil is small. Secondly, if the coil size is too large, the equipment required for processing the winding die is more advanced, increasing the difficulty of manufacturing the winding die. In addition, if the coil delivery date is tight, manufacturing the winding die will consume a lot of time, seriously affecting the coil winding progress.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0028] Reference Figure 6 As shown, in the prior art, the winding mold is roughly a tower-shaped aluminum circular stack structure, which is heavy and bulky, has high manufacturing cost, and is inconvenient to use.

[0029] To address the above problems, in one embodiment, reference is made to... Figures 1 to 3 As shown, this utility model provides a coil winding device, which includes a first guide member 1, a first connector 2, a plurality of second guide members 3, a plurality of second connectors 4, a plurality of connecting rods 5, and a plurality of positioning members 6.

[0030] Specifically, the first guide member 1 is generally constructed as a round rod. The first connecting member 2 is slidably sleeved on the first guide member 1 and can move controllably along the axial direction of the first guide member 1. The second guide member 3 is also generally constructed as a round rod, with multiple second guide members 3 arranged around the first guide member 1, each having approximately the same included angle with the first guide member 1. Multiple second connecting members 4 are correspondingly sleeved on the multiple second guide members 3, and each second connecting member 4 can move controllably along the axial direction of the second guide member 3 it is located on. Multiple connecting rods 5 are hinged to the first connecting member 2, and the multiple connecting rods 5 are correspondingly hinged to the multiple second connecting members 4. Multiple positioning members 6 are correspondingly provided on the multiple connecting rods 5, and each positioning member 6 extends from the peripheral wall of its corresponding connecting rod 5 in a direction away from the first guide member 1.

[0031] According to the above structural design, multiple connecting rods 5 form a structure similar to a winding skeleton. After the enameled wire is wound onto the winding skeleton, a coil of the corresponding shape can be obtained. During the winding process, the positioning members 6 can play an auxiliary positioning role. The dimensions of the shape formed by the lines connecting the various positioning members 6 are approximately the dimensions of the coil. The operator can move the first connecting member 2 and the second connecting member 4, adjust the angle between the first guide member 1 and the second guide member 3, and change the length of the lines connecting the various positioning members 6 to adjust the size of the coil.

[0032] In one embodiment, reference is made to Figure 3 As shown, the connecting rod 5 has a radially penetrating through groove 51. The positioning member 6 is at least partially located within the through groove 51 and extends at least partially to the outside of the through groove 51 in a direction away from the first guide member 1. The through groove 51 has a certain length in the axial direction of the connecting rod 5, providing the positioning member 6 with space to move along the axial direction of the connecting rod 5. Without moving the first connecting member 2 and the second connecting member 4, the operator can adjust the size of the coil by moving the positioning member 6.

[0033] In one embodiment, reference is made to Figure 5 As shown, in the direction close to the first guide member 1, the positioning member 6 includes a positioning part 61, a first stop part 62, a connecting part 63, and a second stop part 64 arranged in sequence.

[0034] The positioning part 61 is generally constructed as a round rod structure. The positioning part 61 is located outside the through groove 51 and on the side of the through groove 51 away from the first guide member 1. The first stop part 62 is located on the side of the through groove 51 away from the first guide member 1, and the second stop part 64 is located on the side of the through groove 51 closer to the first guide member 1. The connecting part 63 is located inside the through groove 51 and connects the first stop part 62 and the second stop part 64.

[0035] Furthermore, the connecting part 63 is constructed as a cylindrical structure and is threadedly connected to the second stop part 64. Twisting the second stop part 64 can adjust the distance between the first stop part 62 and the second stop part 64, so that the positioning member 6 has a locked state and an unlocked state.

[0036] When the positioning member 6 is in the locked state, the first stop 62 and the second stop 64 cooperate to clamp the connecting rod 5, fixing the positioning member 6 to the connecting rod 5 and restricting the positioning member 6 from moving along the axial direction of the connecting rod 5.

[0037] When the second stop 64 is loosened, the second stop 64 moves away from the first stop 62, and the positioning member 6 switches from the locked state to the unlocked state. The operator can then drive the positioning member 6 to move along the axial direction of the connecting rod 5.

[0038] In one embodiment, reference is made to Figure 3 and Figure 4 As shown, in the direction close to the first guide member 1, the through groove 51 includes a first groove 511 and a second groove 512 arranged in sequence. The width of the first groove 511 is greater than the width of the second groove 512. A stop surface 52 is formed at the junction of the first groove 511 and the second groove 512. The connecting part 63 passes through the second groove 512. The first stop part 62 is located in the first groove 511. When the positioning member 6 is in the locked state, the first stop part 62 abuts against the stop surface 52.

[0039] After the first stop 62 is housed in the second groove 512, only the positioning part 61 protrudes from the connecting rod 5 on the positioning member 6, thus avoiding unevenness in the part of the positioning member 6 that protrudes from the connecting rod 5, which would affect the quality of the wound coil.

[0040] Furthermore, two anti-rotation surfaces 53 are formed in the first groove 511 along the extension direction perpendicular to the positioning member 6. The first stop part 62 abuts against the two anti-rotation surfaces 53. The two anti-rotation surfaces 53 can restrict the rotation of the first stop part 62, so that the operator can screw the second stop part 64.

[0041] In one embodiment, each connecting rod 5 is provided with a plurality of positioning elements 6 arranged at intervals along its axial direction, allowing the operator to simultaneously wind multiple coils of different sizes.

[0042] In one embodiment, the positioning member 6 extends generally along the radial direction of the connecting rod 5.

[0043] It should be noted that in the above embodiments, only the second stop 64 is threadedly connected to the connecting part 63. In other embodiments, without restricting the rotation of the first stop 62, the first stop 62 can also be threadedly connected to the connecting part 63. In this case, turning the first stop 62 can also adjust the distance between the first stop 62 and the second stop 64.

[0044] In one embodiment, reference is made to Figure 2 As shown, the first connecting member 2 includes a first ring portion 21, a plurality of rod portions 22, and a plurality of second ring portions 23. The first ring portion 21 is slidably sleeved on the first guide member 1, the plurality of rod portions 22 extend radially from the peripheral wall of the first ring portion 21, and the plurality of second ring portions 23 are fixedly sleeved on the plurality of rod portions 22 in a corresponding manner and are hinged to the plurality of connecting rods 5 in a corresponding manner.

[0045] In one embodiment, reference is made to Figure 1 As shown, a third connecting member 7 is fixedly sleeved on the first guide member 1, and all the second guide members 3 are fixedly connected to the third connecting member 7. The first guide member 1 is approximately perpendicular to the second guide member 3, and the included angle between the first guide member 1 and the second guide member 3 is approximately 90°.

[0046] Optionally, four second guide members 3 and four connecting rods 5 are provided. The shape formed by the connecting lines between the positioning members 6 on each connecting rod 5 is approximately rectangular, so as to facilitate the operator to wind a rectangular coil.

[0047] In other embodiments, the included angle between the first guide member 1 and the second guide member 3 can also be adjusted according to actual needs, and the included angle between the two is not limited to 90°.

[0048] In other embodiments, the number of the second guide member 3 and the connecting rod 5 can be adjusted according to the shape of the coil. For example, when a triangular coil needs to be wound, three second guide members 3 and three connecting rods 5 can be provided. For example, when a pentagonal coil needs to be wound, five second guide members 3 and five connecting rods 5 can be provided.

[0049] It should be noted that, in order to reduce manufacturing costs and decrease the frictional resistance when the first connecting member 2 and the second connecting member 4 move, the first guide member 1 and the second guide member 3 in the above embodiments are constructed as relatively smooth round rod structures. In other embodiments, the first guide member 1 and the second guide member 3 may also be configured as a structure similar to a guide rail, and the first connecting member 2 and the second connecting member 4 may be configured as a structure similar to a slider.

[0050] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0051] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style of the specification is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
