Abstract
Description
Technical Field
[0001] This utility model belongs to the field of coil production technology, specifically relating to a coil winding tool. Background Technology
[0002] Currently, the production process of motor coils involves winding copper wire. To ensure a precise fit between the coil and the stator core, the copper wire needs to be wound into a specific shape to improve the motor's performance and reliability. Traditional coil processing methods typically involve winding the coil into a circle and then shaping it through extrusion molding. This method is inefficient and carries the risk of coil damage. Therefore, a coil winding fixture has been designed to address these issues.
[0003] It should be noted that the above introduction to the technical background is only for the purpose of providing a clear and complete explanation of the technical solutions of this utility model and facilitating understanding by those skilled in the art. It should not be assumed that these technical solutions are known to those skilled in the art simply because they have been described in the background section of this utility model. Utility Model Content

In this solution, according to customer requirements, the positions of the first limiting group in the length direction of the winding bracket and the second limiting group in the width direction of the winding bracket are first adjusted, then copper wire is wound onto the fixture, and winding is achieved by rotating the winding bracket on the wire feeding frame. After the copper wire is wound into a coil of a specific shape, it is removed and taken out.
[0006] Furthermore, the first limiting group includes a first base plate, a first limiting block, and a first baffle. The first base plate is disposed on the winding bracket, the first limiting block is disposed on the first base plate, and the first baffle is detachably disposed on the upper end of the first limiting block. In this design, the copper wire is wound around the first limiting block one turn at a time. The first baffle and the first base plate can limit the winding at both the upper and lower positions. After the coil is wound, the coil can be removed by disassembling the first baffle.
[0007] Furthermore, the outer surface of the first limiting block that contacts the coil is designed as an arc surface, and the cross-section of the first limiting block is semi-circular. In this design, the arc surface design can protect the coil, making it less likely to be damaged and ensuring product quality.
[0008] Furthermore, the first baffle and the first base plate are arranged parallel to each other, and both are disc-shaped. In this design, the disc shape facilitates production and can also provide better limiting of the coil at both the upper and lower positions.

The second base plate is mounted on the winding bracket, the second limiting block is mounted on the second base plate, and the second baffle is detachably mounted on the upper end of the second limiting block. In this design, the copper wire is wound around the second limiting block one turn at a time. The second baffle and the second base plate can limit the winding at both the upper and lower positions. After the coil is wound, the coil can be removed by disassembling the second baffle.
[0010] Furthermore, the outer surface of the second limiting block that contacts the coil is designed as an arc surface, and the second limiting block and the second base plate are integrally formed. In this design, the arc surface design can protect the coil, making it less likely to be damaged and ensuring product quality; the integrally formed structure is more stable.
[0011] Furthermore, the second baffle and the second base plate are arranged parallel to each other, and both are semi-disc shaped. In this design, the semi-disc shape facilitates production and can also provide better limiting of the coil at both the upper and lower positions.
[0012] Furthermore, a drive shaft is provided in the middle of the pay-off frame; the winding bracket is cross-shaped, and the middle of the winding bracket is fixed on the drive shaft. In this design, the drive shaft on the pay-off frame facilitates the installation and rotation of the winding bracket; the cross-shaped structure is simple and also facilitates coil winding.
[0013] Furthermore, a drive device is installed inside the base, and the drive device is connected to the transmission shaft. In this solution, the rotation of the tooling is achieved through the drive device, resulting in a high degree of automation and high winding efficiency.
[0014] Furthermore, the base is made of rigid plastic. This design utilizes its own strength to ensure pressure resistance and extend the base's service life.
[0015] Due to the application of the above technical solution, the beneficial effects of this utility model compared with the prior art are as follows:
[0016] The coil winding fixture designed in this utility model can first adjust the positions of the first and second limit groups to meet the coil shape requirements of different needs, so that the coil and the stator core can be precisely matched to ensure the performance and reliability of the motor. The copper wire can be directly wound into the required shape by rotating the fixture, without the need to shape the coil by extrusion molding, which improves the winding efficiency and solves the problem of coil damage.

In this embodiment, according to customer requirements, the position of the first limiting group 5 in the length direction of the winding bracket 4 and the position of the second limiting group 6 in the width direction of the winding bracket 4 are first adjusted. Then, the copper wire is wound on the tooling, and the winding bracket 4 is rotated on the wire feeding frame 3 to achieve winding. After the copper wire is wound into a coil 1 of a specific shape, it is removed and taken out.
[0028] See appendix Figure 2 and attached Figure 3 As shown, the first limiting group 5 includes a first base plate 51, a first limiting block 52, and a first baffle 53. The first base plate 51 is mounted on the winding bracket 4, the first limiting block 52 is mounted on the first base plate 51, and the first baffle 53 is detachably mounted on the upper end of the first limiting block 52. Copper wire is wound around the first limiting block 52, and the first baffle 53 and the first base plate 51 provide limiting at both the upper and lower positions. After the coil 1 is wound, it can be removed by disassembling the first baffle 53. The outer surface of the first limiting block 52 that contacts the coil 1 is an arc surface, and the cross-section of the first limiting block 52 is semi-circular. The arc surface design protects the coil 1, preventing damage and ensuring product quality. The first baffle 53 is parallel to the first base plate 51, and both are disc-shaped. The disc shape facilitates production and provides good limiting for the coil 1 at both the upper and lower positions.

After the coil 1 is wound, it can be removed by disassembling the second baffle 63. The outer surface of the second limiting block 62 that contacts the coil 1 is set as an arc surface, and the second limiting block 62 and the second base plate 61 are integrally formed. The arc surface design can protect the coil 1, making it less likely to be damaged and ensuring product quality; the integrally formed structure is more stable.
