[0002] A permanent magnet motor is a motor that uses permanent magnets to generate a magnetic field. Permanent magnet motors have the advantages of simple structure, high efficiency, and high power density, and are widely used in various fields. Permanent magnet motors are composed of rotors, stators, etc. The rotor is the main moving part of the permanent magnet motor, consisting of permanent magnets and an iron core. Its function is to generate a magnetic field and interact with the stator to generate a rotational force. The stator is the stationary part of the permanent magnet motor, usually consisting of a winding and an iron core. Its function is to generate electric power through interaction with the rotor's magnetic field. Permanent magnet motors also include some auxiliary components, such as end covers, bearings, and housings.

[0003] like Figure 6 and Figure 8 As shown, in order to meet the performance requirements of the permanent magnet motor, the permanent magnet motor will be magnetized during assembly. However, after the permanent magnet motor is magnetized, the magnetic field generated will affect the rotating shaft 5, causing the rotating shaft to be difficult to adjust the relative position of the rotating shaft 5 and the bearing 7 under the action of the magnetic attraction force, increasing the difficulty of inserting the rotating shaft 5 into the inner hole of the bearing 7. Utility Model Content

[0007] By adopting the above technical solution, the tooling structure is simple and does not require other auxiliary tools. It can be assembled through simple operations, which improves the convenience and efficiency of assembly during use.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1 and Figure 5 As shown, the utility model is a motor installation tool, which is used to quickly insert the rotating shaft 5 into the inner hole of the bearing 7 of the end cover 9, including a base 10 for placing the end cover 9, a clamping assembly 20 detachably fixed on the base 10 and capable of clamping the end cover 9, and a guide assembly 30 detachably fixed on the base 10 for limiting and guiding the motor housing 8 to be clamped onto the end cover 9.

[0025] like Figure 2 , Figure 3 and Figure 7 , wherein the base 10 has a first positioning structure 11 for positioning the end cover 9. The end cover 9 has a second positioning structure 12 adapted to the first positioning structure 11. In this embodiment, the first positioning structure 11 may be a positioning column, and the second positioning structure 12 may be a positioning hole.

[0026] like Figure 2 , Figure 3 and Figure 7 In addition, considering that the end cover 9 can still rotate after the positioning column is inserted into the positioning hole, a first limiting structure 13 for limiting the rotation of the end cover is provided on the base. The end cover 9 has a second limiting structure 14 that cooperates with the first limiting structure 13. In this embodiment, the first limiting structure 13 can be a limiting pin. The second limiting structure 14 can be a limiting hole.

[0027] like Figure 1 and Figure 3As shown, in this embodiment, the clamping assembly 20 includes a pair of detachable brackets 22 respectively arranged on both sides of the end cover and a locking bolt 23 installed on the corresponding bracket 22 and pressed on the edge of the end cover 9. Each bracket 22 is fixed to the base through a pressing plate 21. A mounting port 15 for mounting the bracket 22 is opened on the base 10. Each pressing plate 23 has a notch 24 for the bracket 22 to pass through. When in use, the end cover 9 is first placed on the base and positioned, and then the two brackets are placed in the corresponding mounting ports 15 respectively, and then each pressing plate 21 is placed on the upper surface of the base 10 at the corresponding mounting ports 15 to press the corresponding bracket 22, and the pressing plate 21 is fixed to the base 10 by screws, so as to fix the bracket 22. Among them, each mounting port 15 has sufficient displacement space, and the position of the bracket 22 can be adjusted to be close to or away from the end cover 9 according to actual needs. A threaded hole is opened on the end of the bracket 22 facing the center of the base, and the locking bolt 23 is inserted into the corresponding threaded hole. By tightening the locking bolt 23, the end of the locking bolt 23 passes through the threaded hole and presses on the edge of the end cover 9, thereby pressing the end cover 9, and then placing the bearing 7 in the bearing chamber 6 of the end cover 9. In this way, by inserting the positioning column into the positioning hole and the limiting pin into the limiting hole, the locking bolt 23 presses the end cover 9, and the end cover 9 is firmly fixed on the base 10.

[0028] like Figure 1 , Figure 4 and Figure 5 As shown, in this embodiment, the guide assembly 30 includes a pair of half rings 32. A plurality of support rods 31 are detachably distributed on the base 10 on the outer side of the end cover. A pair of half rings are respectively sleeved on the corresponding support rods 31. Among them, the two half rings 32 form a accommodating cavity adapted to the motor housing 8. During operation, the two half rings 32 are respectively sleeved on the corresponding support rods 31. The two half rings 32 play a limiting guiding role. When the motor housing 8 is located in the accommodating cavity, the rotating shaft 5 in the motor housing 8 is located directly above the inner hole of the bearing 7. In this way, the rotor flange 4 of the motor housing 8 moves downward along the inner walls of the two half rings, which can ensure that the rotating shaft 5 is accurately inserted into the inner hole of the bearing 7.

[0029] like Figure 1 As shown, handles 16 are provided on the left and right sides of the surface of the base 10 respectively.

[0030] like Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, during operation, first place the end cover 9 on the base 10, insert the positioning column into the positioning hole, and insert the limit pin into the limit hole. Then, place each bracket 22 in the corresponding installation port 15, each pressure plate 21 presses the corresponding bracket 22 respectively and fixes it on the base 10 by screws, so as to fix the bracket 22, and then install the locking bolt on the corresponding bracket and press it on the edge of the end cover 9. The bearing 7 is placed in the bearing chamber 6 of the end cover 9. Then, the two half rings 32 are respectively sleeved on the corresponding support rods 31. Then, the rotor flange 4 of the motor housing 8 is moved downward along the inner walls of the two half rings 32, snapped onto the end cover 9, and the assembly is completed. During the process of the motor housing 8 moving downward along the inner walls of the two half rings 32, the rotating shaft 5 in the motor housing 8 is inserted into the inner hole of the bearing 7. Then, remove a pair of half rings 32, loosen the screws to remove the pressure plate 21 and the bracket 22, and then the motor can be removed.

[0031] In summary, the motor installation tool of the utility model has simple assembly operation, ensures that the shaft can be quickly and accurately inserted into the inner hole of the bearing, and can be quickly assembled without the aid of auxiliary tools, has good stability and high practicality.
