[0030] Combination Figures 1-8 The content shown further illustrates the technical solution provided in this application: a motor winding bracket, including a support rod 1 and a spacer group 2 disposed on the support rod 1. The spacer group 2 is used for winding the winding. The spacer group 2 includes a first end spacer 20 disposed on one end of the support rod 1, a second end spacer 21 disposed on the other end of the support rod 1, and one or more main spacers 22 disposed between the first end spacer 20 and the second end spacer 21. The main spacers 22 can be spaced apart along the length direction of the support rod 1. Adjacent main spacers 22 together form a winding area 3, which is used for winding the winding.

[0031] This application provides a motor winding bracket, which includes a support rod and a group of spacers disposed on the support rod. The group of spacers includes a first end spacer and a second end spacer respectively disposed at both ends of the support rod, and a plurality of main spacers disposed between the first end spacer and the second end spacer. By setting a plurality of spaced main spacers on the support rod, adjacent main spacers can jointly form a winding area, which can be used for winding of the winding. It can replace the traditional circular winding bracket, facilitates programming the winding path of automatic winding equipment, and has strong adaptability. When it is necessary to wind motors of different specifications, the winding requirements of different specifications of motors can be met by adjusting the number of main spacers. There is no need to design a separate winding bracket injection mold, which significantly reduces production costs and improves production efficiency. It has the advantages of simple structure, easy operation, low implementation cost, and easy promotion and implementation.

[0032] In this embodiment, the main spacer 22 includes a main body 220, a connecting hole 221 in the middle of the main body 220, and blocking portions 222 protruding on both sides of the main body 220. The main spacer 22 is matched and passed through the connecting hole 221 onto the support rod 1. When multiple main spacers 22 are matched and disposed on the support rod 1, adjacent main spacers 22 are in contact with each other, and the blocking portions 222 between adjacent main spacers 22 together form the winding area 3 for winding of the winding.

[0033] In this embodiment, one side of the main body 220 is defined as side A, and the other side of the main body 220 is defined as side B. The blocking part 222 is respectively provided on side A and side B, and the two blocking parts 222 are centrally symmetrically distributed with the center of the main body 220 as the center of symmetry.

[0034] In actual implementation, the structural difference between the first end partition and the main partition is that the first end partition only has a blocking part on side A, and no blocking part on side B.

[0035] The structural difference between the second end partition and the main partition is that the second end partition only has a blocking part on side B, and no blocking part on side A.

[0036] The blocking portions on the first end partition and the blocking portions on the second end partition are centrally symmetrically distributed relative to the axis of the support shaft.

[0037] In actual implementation, by setting the barrier in a symmetrical manner, the assembly speed of the main partition can be effectively improved.

[0038] In this embodiment, the blocking part 222 includes a horizontal part 40 disposed on the side of the main body 220 and a vertical part 41 disposed at both ends of the horizontal part 40. The horizontal part 40 and the vertical part 41 together form a first clearance groove 42. The cross-sectional shape of the blocking part 222 is "C".

[0039] In actual implementation, the barrier is located on the outer periphery of the connecting hole. By setting the first clearance groove, clearance can be provided for the connecting hole, thereby improving the smoothness of assembly between the main partition and the support rod.

[0040] In this embodiment, the main body 220 is provided with a second clearance groove 5. There are two second clearance grooves 5 along the height direction of the main body 220, and the two second clearance grooves 5 are symmetrically arranged with respect to the center of the main body 220.

The second clearance groove 5 includes a horizontal extension and an inclined portion provided at both ends of the horizontal extension. The inclined portion is inclined in a direction away from the blocking portion 222.

[0042] In actual implementation, by setting a "V"-shaped second clearance slot, after the winding is matched and wound on the winding area, the second clearance slot can be connected with the winding, which makes it easy to attach an anti-crossflow layer on the winding and improve the anti-interference capability of the winding.

[0043] In the implementation of this embodiment, in the motor winding bracket,

[0044] Define the angle between the horizontal extension and the inclined portion as C;

[0045] The C satisfies the following relationship: 120°≤C≤135°.

[0046] In actual implementation, C = 120°.

[0047] In this embodiment, the connecting hole 221 includes a main hole 60 and a plurality of clearance holes 61 disposed on the main hole 60. The cross-sectional shape of the main hole 60 is square, and the cross-sectional shape of the clearance holes 61 is circular. The plurality of clearance holes 61 are respectively disposed at the four corners of the main hole 60.

[0048] In the implementation of this embodiment, in the motor winding bracket,

[0049] The diameter of the clearance hole 61 is defined as D;

[0050] The diameter of the main hole 60 is defined as E;

[0051] The relationship between D and E is as follows: 8.5 ≤ E / D ≤ 12.5.

[0052] In actual implementation, E / D = 10.

[0053] In this embodiment, a first limiting member 7 and a second limiting member 8 are provided on both ends of the support rod 1. The first limiting member 7 can abut against the first end partition 20 or the second end partition 21, and the second limiting member 8 can abut against the first end partition 20 or the second end partition 21 to restrict the partition group 2 from moving away from the support rod 1.

[0054] This application provides a motor winding bracket, which includes a support rod and a group of spacers disposed on the support rod. The group of spacers includes a first end spacer and a second end spacer respectively disposed at both ends of the support rod, and a plurality of main spacers disposed between the first end spacer and the second end spacer. By setting a plurality of spaced main spacers on the support rod, adjacent main spacers can jointly form a winding area, which can be used for winding of the winding. It can replace the traditional circular winding bracket, facilitates programming the winding path of automatic winding equipment, and has strong adaptability. When it is necessary to wind motors of different specifications, the winding requirements of different specifications of motors can be met by adjusting the number of main spacers. There is no need to design a separate winding bracket injection mold, which significantly reduces production costs and improves production efficiency. It has the advantages of simple structure, easy operation, low implementation cost, and easy promotion and implementation.
