Description

[0002] With the development of magnetic levitation technology, people are using magnetic levitation motors more and more widely, and the production scale of motors is also growing. While bringing profits to suppliers, this also brings challenges to the manufacture of motors. The production and manufacturing process of magnetic levitation motors is extremely complex, with a long manufacturing cycle and high manufacturing difficulty. Among them, the disassembly and installation of the rotor alone requires a lot of manpower and material resources, and the disassembly and assembly process needs to be extremely careful.

[0003] At present, the disassembly and assembly of the magnetic levitation motor rotor requires the help of tooling. After using a guide tool to determine the axial and radial positions of the rotor, it is inserted into the stator housing to ensure that the rotor is in the middle of the coil. The rotor cannot be guaranteed to be stable during disassembly and assembly. It is easy for the rotor to collide with the stator structure due to the suction force of the rotor itself, causing damage to the rotor. This is time-consuming and labor-intensive. If there is a large order volume, there will be a shortage of supply, making it difficult to meet the supply requirements. Utility Model Content

DETAILED DESCRIPTION

[0020] The following combination Figure 1-Figure 5 The utility model is described in further detail.

[0021] The embodiment of the utility model discloses a disassembly and assembly tool for a magnetic levitation motor rotor.

[0022] Reference Figure 1 , a disassembly and assembly tool for the rotor of a magnetic levitation motor, comprising a rotor 1 and a stator structure 2, with a support assembly 3 and a positioning sleeve 4 respectively installed at both ends of the stator structure 2. The positioning sleeve 4 is a through-type design with upper and lower ends. The rotor 1 is arranged inside the stator structure 2 and one end of the rotor 1 is connected to a rotor guide column 5. The rotor guide column 5 is arranged and supported on the support assembly 3. A thrust plate 6 is fixed around the end of the rotor 1 away from the rotor guide column 5. The edge of the thrust plate 6 is tightly fitted with the inner end surface of the positioning sleeve 4. The guiding effect of the two ends of the rotor 1 is used to ensure that the rotor 1 always remains in a vertical state when the rotor 1 is installed.

[0023] Reference Figure 1 、 Figure 2 A threaded round steel bar 7 is provided at the connection position between the rotor 1 and the rotor guide column 5. An axial hole 8 is opened inside the rotor guide column 5 along the axis. The main part of the threaded round steel bar 7 is fixedly clamped in the axial hole 8. A screw hole is provided at the end of the rotor 1, and the extended end of the threaded round steel bar 7 is spirally fastened to the rotor 1.

[0024] Reference Figure 1 、 Figure 4 The support assembly 3 includes a protective bearing 9 and a bearing seat 10. A positioning hole 11 is opened in the center of the protective bearing 9. The rotor guide column 5 passes through the positioning hole 11 and the outer end surface of the rotor guide column 5 is in contact with the positioning hole 11. The extended end of the rotor guide column 5 is supported on the bearing seat 10.

[0025] Reference Figure 1 、 Figure 5 The stator structure 2 includes a stator housing 12 and a stator coil 13 wound inside the stator housing 12. The rotor 1 is arranged at the axial position of the stator coil 13. The stator coil 13 is adapted to the permanent magnet 14 embedded in the outer end surface of the rotor 1. The guiding effect of the two ends of the rotor 1 is utilized to prevent the permanent magnet 14 embedded in the rotor 1 and the stator coil 12 from colliding with each other due to magnetic attraction and causing damage.

[0026] Reference Figure 1 、 Figure 3 A positioning bolt hole 15 is opened on the side of the positioning sleeve 4 close to the stator housing 12, and the positioning sleeve 4 is connected to the stator housing 12 by bolts 16.

[0027] Reference Figure 1The stator housing 12 is mounted on an external bracket 17 , and the vertical mounting facilitates the installation of the combined structure of the rotor 1 and the rotor guide column 5 into the stator structure 2 .

[0028] Reference Figure 1 、 Figure 2 , the rotor guide column 5 is made of nylon.

[0029] The implementation principle of the disassembly and assembly tool of the magnetic levitation motor rotor in the embodiment of the present utility model is as follows:

[0030] The specific installation process is to install the support assembly 3 and the positioning sleeve 4 at both ends of the stator structure 2 respectively, and vertically mount the stator shell 12 of the motor stator structure 2 on the bracket 17, with one end of the support assembly 3 installed facing downward and one end of the positioning sleeve 4 installed facing upward, and then fasten the rotor guide column 5 to the end of the rotor 1 away from the thrust plate 6, and slowly install the combined structure of the rotor 1 and the rotor guide column 5 into the stator structure 2 from the top of the motor, wherein the rotor guide column 5 is passed through and supported on the support assembly 3, and the edge of the thrust plate 6 is tightly fitted with the inner end face of the positioning sleeve 4, so that the guiding effect of the two ends is utilized to ensure the stability of the installation of the rotor 1, and the rotor 1 always remains in a vertical state. The position of the combined structure of the moving rotor 1 and the rotor guide column 5 in the stator structure 2, the stator coil 13 corresponds to the position of the permanent magnet 14 embedded in the outer end face of the rotor 1.

[0031] When disassembling the rotor 1, the guide column 5 and the support assembly 3 of the rotor 1 are disassembled, and then the rotor 1 is slowly taken out from the stator housing 12 through the lifting assembly. With the help of the guiding effect at both ends, the rotor 1 can still be kept in a vertical state.

Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
