[0007] Preferably, the disassembly base is provided with a U-shaped limiting groove.

[0008] Preferably, the diameter of the U-shaped limiting groove opening is greater than or equal to the diameter of the magnetic rotor shaft.

[0009] The beneficial effects of adopting the above technical solution include at least the following: the larger U-shaped groove can conveniently place the shaft of the magnetic rotor inside the U-shaped groove, which facilitates operation.

[0010] Preferably, a bolt hole is provided at the center of the fixing base.

[0011] The beneficial effects of adopting the above technical solution include at least the following: applying external force to the magnetic rotor shaft through the mechanical movement of the bolt adapted to the bolt hole to achieve dismantling.

[0012] Preferably, the transition component connecting the disassembly seat is a semi-cylindrical component on one side, and the connecting fixing seat is a circular component on the other side, with an anti-detachment flange provided on the outer edge of the circular component.

[0013] The beneficial effects of adopting the above technical solution include at least the following: the semi-cylindrical component ensures the transmission of force between the fixed seat and the disassembly seat while effectively accommodating the magnetic rotor; the anti-detachment flange reduces the range of motion of the magnetic rotor during rotation and prevents the magnetic rotor from detaching from the auxiliary tool.

[0014] Preferably, the transition component is a one-piece molded structure.

[0015] The beneficial effects of adopting the above technical solution include at least the following: the one-piece molded structure is more stable and reliable.

[0016] Preferably, the auxiliary tools are made of non-magnetic stainless steel.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] In the description of this utility model, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used solely for the convenience of describing this utility model and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly, for example, it can be a fixed connection, a detachable connection, or an integral connection; for those skilled in the art, the specific meaning of the above term in this utility model can be understood according to the specific circumstances.

[0024] Referring to the attached drawings: An auxiliary tool for dismantling a magnetic rotor includes: a dismantling base 1, a transition piece 2, and a fixing base 3; the dismantling base 1 and the fixing base 3 are symmetrically arranged on both sides of the transition piece 2 and are fixedly connected to the transition piece 2; the dimensions of the dismantling base 1, the fixing base 2, and the transition piece 3 are all adapted to the dimensions of the magnetic rotor; the components adapted to the dimensions of the magnetic rotor help to limit the displacement of the magnetic rotor during the dismantling process.

[0025] The technical solution has been further optimized, and a U-shaped limiting groove 5 is provided on the disassembly base.

[0026] Further optimize the technical solution: the opening diameter of the U-shaped limiting groove 5 is greater than or equal to the diameter of the magnetic rotor shaft; the larger U-shaped limiting groove 5 can conveniently place the magnetic rotor shaft inside the U-shaped limiting groove 5, which is convenient for operation.

[0027] To further optimize the technical solution, a bolt hole 4 is provided at the center of the fixed base 3; the mechanical movement of the bolt adapted to the bolt hole 4 applies force to the rotating shaft of the magnetic rotor, causing the magnetic rotor to follow the auxiliary tool and move in the direction of detachment from the rotating shaft, thus overcoming the magnetic force through mechanical movement.

[0028] The technical solution is further optimized. The side of the transition piece 2 that connects to the disassembly seat 1 is a semi-cylindrical component, and the side that connects to the fixing seat 3 is a circular component. The outer edge of the circular component is provided with an anti-detachment flange 6. The semi-cylindrical component ensures the transmission of force between the disassembly seat 1 and the fixing seat 3 while ensuring effective accommodation of the magnetic rotor. The anti-detachment flange 6 reduces the range of movement of the magnetic rotor during rotation and prevents the magnetic rotor from detaching from the auxiliary tool.

[0029] The technical solution has been further optimized, and the transition part 2 is now a one-piece molded structure; the one-piece molded structure is more stable and reliable.

[0030] The technical solution has been further optimized. The auxiliary tool is made of non-magnetic stainless steel. The use of non-magnetic stainless steel prevents the magnetic rotor from becoming magnetic after being removed from the shaft.

[0031] In one feasible embodiment, the outer diameter of the fixing base 3 is 108mm and the thickness is 10mm, and the bolt hole size is M16; the outer diameter of the transition piece 2 is 108mm and the thickness is 6mm; the outer diameter of the anti-detachment flange is 108mm, the wall thickness is 6mm and the height is 5mm.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
