[0002] When processing a fan motor rotor, it is necessary to wind it. The winding process of the rotor is generally completed by winding equipment. The winding equipment is usually equipped with winding fixtures for fixing the rotor. The existing winding fixtures have relatively complex structures. Generally, the rotor is fixed and clamped by means of screws, such as limiting parts and fixture base. This method is relatively inefficient during rotor assembly and disassembly, which is not conducive to improving the overall work efficiency.

[0003] Therefore, further improvements are needed. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a winding fixture for a fan motor rotor. The limiting component can quickly fix or loosen the motor rotor. The limiting component does not need to be repeatedly disassembled and reassembled with the fixture base, which improves the disassembly and assembly efficiency between the motor rotor and the fixture base, thereby improving the processing efficiency of the motor rotor.

[0005] The purpose of this utility model is achieved as follows:

[0006] A winding fixture for a fan motor rotor includes a fixture base for placing the motor rotor. A limiting component is movably connected to the fixture base. The limiting component and the fixture base are connected and engaged, enabling a first usage state and a second usage state. In the first usage state, the limiting component fixes the motor rotor to the fixture base. In the second usage state, the limiting component releases its limiting effect on the motor rotor, allowing the motor rotor to separate from the fixture base. The limiting component can switch back and forth between the first usage state and the second usage state by moving relative to the fixture base.

[0007] As a specific embodiment, the limiting component includes a first limiting member and a second limiting member.

[0008] As a specific embodiment, the central axis of the first hollowed-out groove coincides with the vertical center of the tooling base.

[0009] As a specific embodiment, the tooling base has an upwardly protruding central positioning post at its center, and the inner side of the central positioning post is hollowed out to form a first hollow groove.

[0010] As a specific solution, a return spring is provided between the first movable arm and / or the second movable arm and the outer side of the tooling base. The return spring can push the first movable arm and the second movable arm to swing upward around the rotation axis so that the first fastening part and the second fastening part expand outward symmetrically to form a first use state.

[0011] As a specific solution, a positioning mechanism for positioning the reset spring is provided between the limiting component and the tooling base. The positioning mechanism includes a positioning groove and a positioning protrusion. The positioning groove is provided on the tooling base, and the positioning protrusion is provided on the first movable arm and the second movable arm. One end of the reset spring abuts against the inner side of the positioning groove, and the other end of the reset spring is sleeved on the outer side of the positioning protrusion.

[0012] As a specific solution, the upper side of the first fastening part and / or the second fastening part is provided with a guide slope, which is inclined from bottom to top toward the center of the first hollow groove.

[0013] As a specific embodiment, the tooling base has several auxiliary positioning posts distributed on its outer center position, and the auxiliary positioning posts are evenly distributed circumferentially on the outer center of the tooling base.

[0014] The beneficial effects of this utility model are:

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] First embodiment:

[0026] See Figures 1-7The winding fixture for the fan motor rotor includes a fixture base 2 for placing the motor rotor 1. A limiting component is movably connected to the fixture base 2. The limiting component and the fixture base 2 are connected and can form a first use state and a second use state. In the first use state, the limiting component fixes the motor rotor 1 on the fixture base 2. In the second use state, the limiting component releases its limiting effect on the motor rotor 1, allowing the motor rotor 1 to separate from the fixture base 2. The limiting component can switch back and forth between the first use state and the second use state by relative movement with the fixture base 2. The limiting component can quickly fix or release the motor rotor 1 without repeated disassembly and assembly of the limiting component with the fixture base 2, which improves the disassembly and assembly efficiency between the motor rotor 1 and the fixture base 2, thereby improving the processing efficiency of the motor rotor 1.

[0027] Furthermore, the limiting assembly includes a first limiting member 31 and a second limiting member 32. The first limiting member 31 includes a first fastening part 311 and a first movable arm 312. The second limiting member 32 includes a second fastening part 321 and a second movable arm 322. The tooling base 2 is provided with a first hollow groove 21 and a second hollow groove 22. The first hollow groove 21 is arranged vertically, with its upper end opening on the upper side of the tooling base 2. The second hollow groove 22 is arranged horizontally on the lower side of the first hollow groove 21, with both ends of the second hollow groove 22 being open. The first fastening part 311 and the second fastening part 321 are symmetrically arranged in the first hollow groove 21. The first movable arm 312 and the second movable arm 322 are symmetrically arranged in the first hollow groove 21. Inside the second hollowed-out groove 22, a rotating shaft 33 is provided between the first movable arm 312 and the second movable arm 322. The rotating shaft 33 is connected and cooperates with the tooling base 2. The first movable arm 312 and the second movable arm 322 swing upward around the rotating shaft 33, causing the first fastening part 311 and the second fastening part 321 to expand outward symmetrically to form a first use state. The first movable arm 312 and the second movable arm 322 swing downward around the rotating shaft 33, causing the first fastening part 311 and the second fastening part 321 to retract inward symmetrically to form a second use state. The overall structure of the limiting component is simple, which can not only achieve the effect of quickly fixing or loosening the electronic rotor, but also is not prone to failure. The limiting component as a whole has good reliability.

[0028] Furthermore, the central axis of the first hollow groove 21 coincides with the vertical center of the tooling base 2, so that the pressure of the limiting component on the motor rotor 1 is concentrated near the center, making the motor rotor 1 more stable during processing and reducing the chance of the electronic rotor shaking on the tooling base 2.

[0029] Furthermore, the tooling base 2 has an upwardly protruding central positioning post 23 at its center. The inner side of the central positioning post 23 is hollow and forms a first hollow groove 21. The central positioning post 23 can further improve the installation accuracy between the motor rotor 1 and the tooling base 2.

[0030] Furthermore, a return spring 4 is provided between the first movable arm 312 and / or the second movable arm 322 and the outer side of the tooling base 2. The return spring 4 can push the first movable arm 312 and the second movable arm 322 to swing upward around the rotation axis 33, so that the first fastening part 311 and the second fastening part 321 expand outward symmetrically to form a first use state. The return spring 4 can enable the first movable arm 312 and the second movable arm 322 to quickly cooperate to press the motor rotor 1.

[0031] Furthermore, a positioning mechanism for positioning the reset spring 4 is provided between the limiting component and the tooling base 2. The positioning mechanism includes a positioning groove 24 and a positioning protrusion 34. The positioning groove 24 is provided on the tooling base 2, and the positioning protrusion 34 is provided on the first movable arm 312 and the second movable arm 322. One end of the reset spring 4 abuts against the inner side of the positioning groove 24, and the other end of the reset spring 4 is sleeved on the outer side of the positioning protrusion 34, so that the reset spring 4 is not prone to accidental displacement or falling off during use.

[0032] Furthermore, a number of auxiliary positioning posts 25 are distributed on the tooling base 2 at the position corresponding to the outer center of the tooling base 2. The auxiliary positioning posts 25 are evenly distributed circumferentially on the outer center of the tooling base 2, which can further improve the installation accuracy between the motor rotor 1 and the tooling base 2.

[0033] Second embodiment:

[0034] See Figure 8 The difference between this embodiment and the first embodiment is that the upper side of the first fastening part 311 and / or the second fastening part 321 of the winding fixture of the fan motor rotor is provided with a guide slope 35. The guide slope 35 is inclined from bottom to top toward the center of the first hollow groove 21. The motor rotor 1 can open the first fastening part 311 and the second fastening part 321 by pressing down. When the motor rotor 1 is in place, the first fastening part 311 and the second fastening part 321 can be reset and pressed against the motor rotor 1 by the return spring 4.

[0035] The remaining undescribed parts are the same as in the first embodiment and will not be repeated here.

[0036] The above embodiments are merely preferred embodiments of this utility model, and other implementations are also possible. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model, and all such equivalent modifications or substitutions are included within the scope set forth in the claims of this application.
