[0025] Embodiment:

[0026] As Figures 1-5 shown, this embodiment proposes a magnetizing device for a servo motor rotor, including a support tabletop 20, and a magnetizing housing 30 is arranged on the support tabletop 20;

[0027] The bottom of the magnetizing housing 30 is provided with a lower cover plate 10 connected by bolts. A placement groove 12 is opened on the lower cover plate 10, and a positioning assembly 60 is arranged in the placement groove 12. The magnetizing housing 30 is provided with an upper cover plate 40 connected by bolts. A placement through-hole 41 is opened on the upper cover plate 40. The upper cover plate 40 is also provided with a pressing plate 50 that can be lifted and lowered. The pressing plate 50 presses the rotor in the placement through-hole 41, and the positioning assembly 60 clamps and limits the bottom of the rotor.

[0028] In this embodiment, when magnetizing the rotor, the rotor is placed in the placement through-hole 41 and enters the interior of the magnetizing housing 30. Then, the positioning assembly 60 performs positioning processing on the bottom of the rotor. At the same time, the pressing plate 50 is connected to the upper cover plate 40, and the top of the rotor is pressed down through the pressing plate 50. Then, the magnetizing housing 30 magnetizes the rotor.

[0029] The bottom of the rotor is positioned by the positioning component 60 set as above, and the top of the rotor is positioned by the pressing plate 50. During the magnetization process of the rotor, the precise positioning of the rotor during magnetization can be ensured, and the uneven magnetization caused by position deviation can be reduced. In this way, the performance and efficiency of the motor can be improved, and the rotor is stable, which can reduce the vibration and noise that may occur during the magnetization process, thereby reducing the adverse impact on the motor performance. At the same time, the positioning component 60 and the pressing plate 50 can adapt to rotors of different specifications, improving the versatility and practicability of the fixture, and also reducing the production cost.

[0030] Specifically, a magnetic conductive silicon steel 31 is arranged in the magnetization housing 30, and multiple groups of placement racks 33 are arranged in a circular array on the magnetic conductive silicon steel 31, and multiple groups of wire coils 32 are arranged on the placement racks 33.

[0031] In this embodiment, the magnetic conductive silicon steel 31, the placement racks 33 and the wire coils 32 are prior arts and will not be elaborated here.

[0032] Specifically, multiple groups of positioning holes 11 are formed in the lower cover plate 10, and the multiple groups of positioning holes 11 are matched with the positions of the placement grooves 12, and the multiple groups of positioning holes 11 are arranged in a circular array;

[0033] The positioning component 60 includes multiple groups of positioning screws 62, the multiple groups of positioning screws 62 are matched with the multiple groups of positioning holes 11, and the positioning screws 62 are threadedly connected in the positioning holes 11.

[0034] Specifically, a positioning arc plate 63 is arranged on the positioning screw 62, the positioning screw 62 is rotatably connected with the positioning arc plate 63, and the positioning arc plate 63 is slidably connected with the bottom of the placement groove 12;

[0035] The positioning screw 62 displaces in the positioning hole 11, so that the positioning arc plate 63 displaces towards the center direction of the placement groove 12.

[0036] In this embodiment, when positioning the bottom of the rotor, the positioning screws 62 are respectively rotated. Through the threaded cooperation between the positioning screws 62 and the positioning holes 11, the positioning arc plate 63 is displaced towards the center direction of the placement groove 12 until the positioning arc plate 63 contacts the rotor;

[0037] Of course, during the rotational displacement of the positioning screw 62, the rotor remains at the center position of the placement groove 12.

[0038] Specifically, a protective pad 61 is arranged on the positioning arc plate 63, and the protective pad 61 is fixedly connected with the positioning arc plate 63.

[0039] In this case, the protective pad 61 is made of a high-temperature resistant rubber material.

[0040] In this embodiment, the protective pad 61 can improve the protection ability and prevent damage to the bottom of the rotor caused by hard contact.

[0041] Specifically, two groups of fixing blocks 52 are symmetrically arranged on the upper cover plate 40, and fixing holes are formed in the fixing blocks 52;

[0042] Two groups of fixing screws 53 are symmetrically arranged on the pressing plate 50. The fixing screws 53 are rotatably arranged on the pressing plate 50, and the fixing screws 53 are in threaded connection with the fixing holes.

[0044] In this embodiment, when limiting the top of the rotor, the rotor is placed in the placing groove 12. Then, the pressing plate 50 is placed above the rotor, and the fixing screws 53 are inserted into the fixing holes. Then, the fixing rod 51 rotates to drive the fixing screws 53 to rotate. Through the threaded cooperation between the fixing screws 53 and the fixing holes, the pressing plate 50 descends to contact the rotor, and the rotor is pressed in the placing groove 12;

[0045] Of course, the external hexagonal block 54 is used to drive the fixing rod 51 to rotate by a wrench.
