Description

Technical Field

[0001] This utility model relates to the field of motor technology, specifically to a winding fixture for a segmented stator and a motor stator winding device. Background Technology

[0002] The stator is an important component of an electric motor. It consists of three parts: the stator core, the stator windings, and the frame. The main function of the stator is to generate a rotating magnetic field, while the main function of the rotor is to be cut by magnetic lines of force within this rotating magnetic field, thereby generating (output) current.

[0003] In existing winding fixtures, when winding segmented stators, the wire can only pass through the upper side of the stator. This results in excessively high stacked wires when the motor is assembled because only one side is wired. However, there are specific requirements for the height of the bridge wires in the motor. Since the assembled motor only has wire passing through one side, the height of the bridge wires is unacceptable. In order to control the height of the bridge wires to meet the requirements, an additional device is needed to press the bridge wires. Although the wire height can be reduced in the end, it will cause wire damage, resulting in potential quality problems. Moreover, this problem is currently difficult to detect, and there is a quality risk when the product reaches customers and the market. Utility Model Content

[0035] Please see Figure 1This utility model provides a winding fixture for a segmented stator, including: a positioning seat 10, multiple upper wire passing components 20 and multiple lower wire passing components 30, wherein the multiple upper wire passing components 20 and multiple lower wire passing components 30 are arranged in a spaced manner around the positioning seat 10.

[0036] The side of the positioning seat 10 is provided with a plurality of stator positioning parts 11, which are arranged between the upper wire guide assembly 20 and the adjacent lower wire guide assembly 30. The guide seat 12 is provided with a guide rail 121 extending in the vertical direction. The top of the upper wire guide assembly 20 is provided with an upper wire guide groove 21. The bottom of the lower wire guide assembly 30 is provided with a lower wire guide groove 31. The lower wire guide assembly 30 is movably connected to the guide rail 121. The lower wire guide assembly 30 can move downward along the guide rail 121 to the winding position and upward to the avoidance position. The lower wire guide assembly 30 is provided with a positioning member 32. When the lower wire guide assembly 30 moves to the winding position, the positioning member 32 is positioned and engaged with the positioning seat 10.

[0037] The working principle of the winding fixture for a segmented stator according to one embodiment of the present invention is explained below:

[0038] The motor's segmented stator assembly has multiple segmented stators 50, which are positioned and engaged with the stator positioning section 11. When the copper wire passes around the segmented stator 50 and reaches an adjacent segmented stator 50, if the two adjacent segmented stators 50 are lower wire guide assemblies 30, the copper wire will pass through the lower wire guide slot 31; if the two adjacent segmented stators 50 are upper wire guide assemblies 20, the copper wire will pass through the upper wire guide slot 21. Because the copper wire passes through the lower wire guide slot 31 and the upper wire guide slot 21, the copper wire can be distributed within the lower wire guide slot 31 and the upper wire guide slot 21. Therefore, the height of the wire bridge section formed within the lower wire guide slot 31 and the upper wire guide slot 21 is controlled, thereby effectively reducing the number of wire bridges on one side of the stator, avoiding quality problems caused by wire pressing, and effectively improving the problem of wire bridge height.

[0039] After the winding is completed, the positioning member 32 is released from the positioning engagement with the positioning seat 10, and then the lower wire guide assembly 30 is moved upward to the clearance position, so that the copper wire located in the lower wire guide groove 31 can easily be removed from the lower wire guide groove 31. After the copper wire in the lower wire guide groove 31 is removed from the lower wire guide groove 31, the segmented stator 50 is removed from the positioning part, and the segmented stator 50 and the copper wire located in the upper wire guide groove 21 are moved upward together, so that the copper wire is removed from the upper wire guide groove 21, thereby completing the unloading of the segmented stator 50.

[0040] It should be noted that the avoidance position can be a range of locations, not limited to a fixed location.

[0041] In some optional embodiments, the positioning element 32 is a positioning spring. When the lower wire guide assembly 30 moves to the winding position, the positioning spring engages with the positioning seat 10. After the winding is completed, the positioning spring is moved to release the positioning engagement with the positioning seat 10. Then the lower wire guide assembly 30 moves upward to the clearance position, at which point the positioning spring undergoes elastic deformation. When the next winding is required, the lower wire guide assembly 30 moves downward to the winding position again, and the positioning spring engages with the positioning seat 10 again under its own elastic force.

[0042] The positioning engagement between the positioning spring and the positioning seat 10 can be designed according to actual needs. For example, a protruding positioning block can be formed on the positioning seat 10, and the positioning spring abuts against the positioning block to achieve the positioning engagement between the positioning spring and the positioning seat 10. In some optional embodiments, the guide rail 121 is a guide channel set on the guide seat 12, and a first support part 122 is formed on one side of the bottom port of the guide channel. The lower wire guide assembly 30 passes through the guide channel, and a limiting part 33 is provided on the positioning spring. The limiting part 33 engages with the support part for limiting. After the winding is completed, the positioning spring can be pressed to make the limiting part 33 disengage from the first support part 122, and then the lower wire guide assembly 30 can be moved upward. Then the positioning spring will enter the guide channel, and the position of the positioning spring is limited by the inner wall of the guide channel, thereby maintaining the elastic deformation of the positioning spring.

[0043] In some alternative implementations, a portion of the lower wire guide assembly 30 extends from the top port of the guide channel outside the guide channel, so that when the lower wire guide assembly 30 is in the avoidance position, the top of the lower wire guide assembly 30 can be pressed down, thereby driving the lower wire guide assembly 30 downward to the winding position, making the operation more convenient.

[0044] In some optional embodiments, the lower wire guide assembly 30 is provided with a limiting member 34 located outside the guide channel. A second support portion 123 is formed on one side of the top port of the guide channel. When the lower wire guide assembly 30 moves to the winding position, the limiting member 34 and the second support portion 123 engage in a limiting cooperation, thereby preventing the lower wire guide assembly 30 from moving excessively when the top of the lower wire guide assembly 30 is pressed down, so that the lower wire guide assembly 30 can stop exactly at the winding position. In addition, the limiting cooperation between the limiting member 34 and the second support portion 123, as well as the limiting cooperation between the first support portion 122 and the limiting portion 33, improves the positional stability of the lower wire guide assembly 30, enabling more accurate winding.

[0045] In some optional embodiments, the positioning base 10 is provided with a plurality of upper locking members 13 and a plurality of upper adjusting grooves 14 extending in the vertical direction. The upper wire guide assembly 20 is slidably engaged with the upper adjusting grooves 14, and the upper locking members 13 are locked in place with the upper wire guide assembly 20. The upper wire guide assembly 20 can adjust its height relative to the upper adjusting grooves 14, thereby adjusting the height of the upper wire guide groove 21 relative to the positioning part, and thus adapting to the size of different segmented stators 50. In this embodiment, the upper locking member 13 is an upper locking screw, which passes through the upper wire guide assembly 20 and then threadedly engages with the positioning base 10, thereby locking the upper wire guide assembly 20.

[0046] In some optional embodiments, the positioning seat 10 is provided with a plurality of lower locking members 15 and a plurality of lower adjusting grooves 16 extending in the vertical direction. The guide seat 12 is provided with a corresponding guide rail 121. The guide seat 12 is slidably engaged with the lower adjusting grooves 16. The lower locking members 15 are locked in place with the guide seat 12. The guide seat 12 adjusts its height position relative to the lower adjusting grooves 16, thereby enabling the lower wire bridge assembly to adjust its height position relative to the lower adjusting grooves 16, thereby adjusting the height of the lower wire groove 31 relative to the positioning part, and thus adapting to the size of different segmented stators 50.

[0047] The structure of the stator positioning part 11 can be designed according to the actual structure of the segmented stator 50. In some optional embodiments, the stator positioning part 11 is a positioning groove formed on the side of the positioning seat 10.

[0048] To better position the segmented stator 50, in some optional embodiments, the winding fixture for the segmented stator further includes an upper fixture 40, which is movably disposed on the top of the positioning seat 10. The positioning groove extends vertically, and a positioning support block 111 is slidably disposed within the positioning groove. A positioning space 112 for positioning the stator is formed between the positioning support block 111 and the upper fixture 40. Before positioning the segmented stator 50, the position of the positioning support block 111 within the positioning groove is adjusted. Then, a portion of the segmented stator 50 is inserted into the positioning groove. Next, the upper fixture 40 is pressed against the top of the positioning seat 10 and the top of the segmented stator 50, thereby pressing the segmented stator 50 tightly within the positioning space 112, thus fixing the segmented stator 50 and facilitating subsequent winding operations. After the winding is completed, the upper fixture 40 moves upward to disengage from the positioning seat 10 and the segmented stator 50. Then, the lower wire guide assembly 30 moves upward to the clearance position, allowing the copper wire to disengage from the lower wire guide groove 31. Then, the segmented stator 50 is moved upward along the positioning groove. During this process, the copper wire also disengages from the upper wire guide groove 21. After the segmented stator 50 disengages from the positioning groove, the segmented stator 50 is unloaded.

[0049] The aforementioned segmented stator winding fixture can be applied to motor stator winding equipment, which includes: the aforementioned segmented stator winding fixture.
