[0002] Outer rotor magnets are commonly used in motor design, especially in some application scenarios that require a compact structure. The magnets are installed on the outer rotor of the motor, opposite the inner stator. This layout allows the motor to have greater torque output while dissipating heat better. The outer rotor design also helps the motor run more smoothly and efficiently because the external weight helps reduce vibration and provide better dynamic balance.

[0003] At present, manual installation is often used when installing outer rotor magnetic tiles. During the manual installation of magnetic tiles, a magnetic tile positioning frame that assists in positioning the magnetic tiles is first fixed in the rotor cup sleeve, and then the workers insert the magnetic tiles into the magnetic tile positioning frame one by one, and finally fix the magnetic tiles firmly in the rotor cup sleeve; however, the degree of insertion of each magnetic tile in the magnetic tile positioning frame varies, and the magnetic tiles are easily broken during the installation process, resulting in low installation efficiency.

Detailed implementation manners

[0030] The following further elaborates on the present application in conjunction with the attached Figures 1-3 drawings.

[0031] An embodiment of the present application discloses an external rotor magnetic tile installation tooling. Referring to Figure 1 and Figure 2 , it includes a bottom plate 1 assembled on a press, and a guide post 2 is fixedly installed on the bottom plate 1. A set of connection holes 11 are penetrated through the bottom plate 1, and a fixing bolt 12 is rotatably arranged in the connection holes 11, and the fixing bolt 12 is threadedly engaged with the guide post 2. This facilitates the quick disassembly and assembly of the bottom plate 1 and the guide post 2 to replace tooling equipment of different specifications, so as to realize the assembly of rotor cup sleeves and magnetic tiles of different specifications.

[0032] Referring to Figure 2 and Figure 3 , a retaining ring 21 is fixedly arranged on the outer side wall of the guide post 2, a guide sleeve 22 is slidably arranged on the guide post 2, the guide sleeve 22 can abut against the bottom of the retaining ring 21, a positioning ring 23 is rotatably arranged on the top of the guide sleeve 22, and the retaining ring 21 can slide within the positioning ring 23. The inner side wall of the positioning ring 23, the outer side wall of the guide post 2, and the top wall of the retaining ring 21 jointly form a magnetic tile groove 24 for placing magnetic tiles. A cup sleeve positioning groove 232 for inserting a rotor cup sleeve is opened on the inner side wall of the top of the positioning ring 23, and an alignment groove 231 adapted to a magnetic tile positioning frame is opened on the bottom wall of the cup sleeve positioning groove 232.

[0033] Referring to Figure 2 and Figure 3When installing the magnetic tile, first insert the magnetic tile positioning frame into the alignment groove 231, and then insert the magnetic tile into the magnetic tile groove 24. The magnetic tile positioning frame separates the adjacent magnetic tiles to ensure the relative position between the magnetic tiles, and the rotor cup sleeve is buckled in the cup sleeve positioning groove 232. Then drive the pressing plate of the press to press down, press and drive the rotor cup sleeve to move down smoothly, and the positioning ring 23 and the guide sleeve 22 are supported by the rotor cup sleeve and move down with the rotor cup sleeve. In this process, the magnetic tile and the magnetic tile positioning frame are pushed into the rotor cup sleeve together with the guide column 2 and the support ring 21. By controlling the downward pressure of the press, the position of the magnetic tile positioning frame and the magnetic tile in the rotor cup sleeve is controlled to ensure the installation position of the magnetic tile, improve the stability of the installation process, and try to avoid the breakage of the magnetic tile during the installation process, thereby improving the installation efficiency.

[0034] In order to automatically pull the guide pin 2 out of the rotor cup, refer to Figure 1 and Figure 2 A spring groove 13 is provided at the top of the bottom plate 1, and a return spring 14 is provided between the guide sleeve 22 and the bottom plate 1. One end of the return spring 14 is fixedly connected to the guide sleeve 22, and the other end of the return spring 14 is inserted into the spring groove 13 and abuts against the bottom wall of the spring groove 13. The return spring 14 drives the guide sleeve 22 away from the bottom plate 1. When the pressing plate of the press is lifted, the return spring 14 drives the guide sleeve 22 away from the bottom plate 1, and the positioning ring 23 reversely lifts the rotor cup sleeve, and the rotor cup sleeve moves up smoothly with the pressing plate, and the guide column 2 is automatically pulled out of the rotor cup sleeve.

[0035] In order to facilitate the realization of the second layer of tooling of the magnetic shoe in the rotor cup sleeve, refer to Figure 2 and Figure 3 Taking the outer rotor of the six-pole motor as an example, a flange 233 is fixedly provided on the outer side of the top of the positioning ring 23. Two positioning holes 2331 for connecting the rotor cup sleeve are provided on the flange 233. The centers of the two positioning holes 2331 are located on the same circumference and are offset from each other by 15 degrees on the circumference. A detachable positioning pin 2332 is inserted into the positioning hole 2331. The side handle of the rotor cup sleeve is docked with different positioning holes 2331, and the positioning pin 2332 is inserted into the positioning hole 2331 to change the circumferential position of the magnetic tile in the rotor cup sleeve. At this time, the magnetic tiles on both sides are offset by 15 degrees in the rotor cup sleeve, and the layer spacing between the two layers of magnetic tiles is controlled by changing the downward pressure of the press plate, so as to facilitate the second layer of tooling of the magnetic tile in the rotor cup sleeve and realize the angle misalignment between the multiple layers of magnetic tiles.

[0036] To ensure the air pressure balance in the rotor cup, refer to Figure 2A first vent hole 15 is formed through the center of the bottom plate 1, and a second vent hole 25 is formed through the center of the guide column 2. The first vent hole 15 and the second vent hole 25 are connected to each other. When the guide column 2 is pushed into the rotor or separated from the cup, the air in the rotor cup is discharged or introduced from the first vent hole 15 and the second vent hole 25, thereby ensuring the air pressure balance in the rotor cup and avoiding the phenomenon of the rotor cup expanding or contracting due to the change of air pressure in the rotor cup, which affects the installation of the magnetic tile.

[0037] The implementation principle of an outer rotor magnetic tile installation tool in an embodiment of the present application is as follows: when installing the magnetic tile, first insert it into the alignment groove 231 in the magnetic tile positioning frame, and then insert the magnetic tile into the magnetic tile groove 24. The magnetic tile positioning frame separates the adjacent magnetic tiles to ensure the relative position between the magnetic tiles, and the rotor cup sleeve is buckled in the cup sleeve positioning groove 232. Then the pressing plate of the press is driven downward, and the rotor cup sleeve moves down smoothly. The positioning ring 23 and the guide sleeve 22 are supported by the rotor cup sleeve and move down together. In this process, the magnetic tile and the magnetic tile positioning frame are pushed into the rotor cup sleeve together with the guide column 2 and the support ring 21. When the pressing plate of the press is lifted, the reset spring 14 drives the guide sleeve 22 away from the bottom plate 1, and the positioning ring 23 lifts the rotor cup sleeve in the opposite direction. The rotor cup sleeve moves up smoothly with the pressing plate, and the guide column 2 is pulled out of the rotor cup sleeve. In this way, the stability of the installation process is improved, the breakage of the magnetic tile during the installation process is avoided as much as possible, and the installation efficiency is improved.

[0038] In addition, if it is necessary to realize the second layer of tooling of the magnetic tiles in the rotor cup sleeve, the side handle of the rotor cup sleeve is docked with different positioning holes 2331, and the positioning pin 2332 is inserted into the positioning hole 2331 to change the circumferential position of the magnetic tiles in the rotor cup sleeve. At this time, the magnetic tiles on both sides are offset from each other in the rotor cup sleeve, and the layer spacing between the two layers of magnetic tiles is controlled by changing the downward pressure of the press plate, so as to facilitate the realization of the second layer of tooling of the magnetic tiles in the rotor cup sleeve and realize the angular misalignment between the multiple layers of magnetic tiles.

[0039] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
