During the disassembly and assembly process of high-speed oil-cooled permanent magnet motors, the attraction between the stator and the rotor must be overcome.

[0003] In the related art, when removing the rotor or stator of the motor from the housing, or installing the stator or rotor into the housing, manual disassembly and assembly is usually used. Due to the instability of manual operation, the assembly accuracy after disassembly and assembly has a great influence on the relative position between the rotor and the stator. Utility Model Content

[0004] Based on this, it is necessary to provide a disassembly tool and a motor disassembly system to address the problem that manual disassembly and assembly can easily affect the motor assembly accuracy.

[0005] In the first aspect, the present application provides a disassembly and assembly tool, which adopts the following technical solution:

[0006] A disassembly and assembly tool comprises a base, a fixing member, a pushing member and a supporting member, wherein the base comprises a supporting portion and a mounting portion connected to each other; the fixing member is arranged on the mounting portion, and the fixing member is used to fix a motor housing to the mounting portion; the pushing member is movably connected to the mounting portion, and the pushing member is configured to be able to extend and retract along the axial direction of the motor to drive the stator or rotor of the motor to be assembled or separated from the motor housing; the supporting member is installed on the supporting portion, and the supporting member is used to receive the motor stator or rotor separated from the motor housing.

[0007] By adopting the above technical solution, during the disassembly or assembly process, the motor housing is fixed to the mounting portion, the rotor or stator can move along the motor axis under the propulsion of the propulsion member, and is received by the supporting member when separated from the housing, so that when the rotor or stator of the motor is partially separated from the housing, it will not be affected by gravity and will not have an inclination angle with the stator or rotor left in the housing, thereby reducing the wear of the stator and the rotor during the disassembly process, which helps to extend the service life of the motor after disassembly and assembly.

[0008] In one embodiment, the fixing member includes at least one pair of clamping parts, all of which are connected to the mounting part, each pair of the clamping parts are symmetrically distributed relative to the central axis of the motor, and the clamping parts can be clamped on the housing of the motor.

[0009] By adopting the above technical solution, the clamping parts are symmetrically distributed relative to the central axis of the motor, which can apply a balanced clamping force and supporting force to the motor, helping to ensure the stability of the connection between the motor and the mounting part.

[0010] In one embodiment, the clamping portion includes a support rod, a pressure head and a clamp, the support rod is installed on the mounting portion, and the pressure head and the clamp are movably connected to a side of the support rod away from the mounting portion; the clamp is used to clamp the housing of the motor, and the pressure head is transmission-connected to the clamp, and the clamp can move closer to or away from the motor housing as the pressure head rotates.

[0011] By adopting the above technical solution, the rotation of the pressure head drives the clamp to rotate synchronously, thereby adjusting the clamping angle of the clamp, and then adjusting the clamping force, so that the disassembly and assembly tool can adapt to the disassembly and assembly needs of motors of different sizes and materials.

[0012] In one embodiment, the fixing member further includes a plurality of insertion portions, all of which are connected to the mounting portion, an extension direction of the insertion portions is parallel to an axial direction of the motor, and the insertion portions can be inserted into a housing of the motor.

[0013] By adopting the above technical solution, the insertion part is inserted into the motor, providing support force for the motor from the inside of the motor, which helps to further improve the fixing effect of the fixing piece.

[0014] In one embodiment, the propulsion member includes a propulsion shaft, the propulsion shaft is threadedly connected to the mounting portion, and the direction of the central axis of the propulsion shaft can coincide with the axial direction of the motor.

[0015] By adopting the above technical solution, the propulsion shaft is threadedly connected to the mounting portion, so that the propulsion shaft can be stably advanced along the axial direction of the motor during rotation, thereby ensuring smooth propulsion.

[0020] In one of the embodiments, the support portion includes a slideway, the extension direction of the slideway is parallel to the axial direction of the motor, and the supporting member includes a sliding portion, and the sliding portion can be slidably mounted on the slideway.

[0021] By adopting the above technical solution, the supporting member can achieve relative displacement with the mounting portion along the axial direction of the motor under the guidance of the slideway, thereby realizing the two operation processes of overlapping with the housing and supporting the disassembled stator or rotor away from the housing, so as to ensure the effective separation between the disassembled stator or rotor and the housing.

[0022] In one embodiment, the supporting member is made of non-magnetic material.

[0023] By adopting the above technical solution, the supporting member itself does not have magnetism, so it will not generate attraction between the stator or the rotor, which helps to further improve the stability of disassembly and assembly.

[0028] 1. During the disassembly or assembly process, the motor housing is fixed to the mounting portion, and the rotor or stator can move along the motor axis under the propulsion of the propulsion member, and is received by the supporting member when separated from the housing, so that when the rotor or stator of the motor is partially separated from the housing, it will not be affected by gravity and will not have an inclination angle with the stator or rotor left in the housing, thereby reducing the wear of the stator and rotor during the disassembly process, which helps to extend the service life of the motor after disassembly and assembly;

[0035] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0036] In the description of the present application, it should be understood that if the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. appear, the orientation or position relationship indicated by these terms is based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application.

[0037] In addition, if the terms "first" or "second" appear, these terms are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of this application, if the term "plurality" appears, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0038] In this application, unless otherwise clearly specified and limited, if the terms "installed", "connected", "connected", "fixed" and the like appear, these terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0039] In the present application, unless otherwise clearly specified and limited, if there is a description that a first feature is "above" or "below" a second feature, etc., or similar descriptions appear, it may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium.

The first feature being "below", "below" and "below" the second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0040] It should be noted that if an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. If an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. If any, the terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used in this application are for illustrative purposes only and do not represent the only implementation method.

[0041] High-speed oil-cooled permanent magnet motors for vehicles are generally composed of rotors, stators, end covers, etc. The stator is usually composed of an iron core and a three-phase winding, and the rotor is usually composed of a rotor core, permanent magnets, a rotating shaft, and bearings. During the disassembly and assembly process of high-speed oil-cooled permanent magnet motors, the attraction between the stator and the rotor must be overcome.

[0042] The stator core is generally made of 0.35-0.5 mm thick silicon steel sheets with an insulating layer on the surface, which are punched and laminated. The inner circle of the stator core is punched with evenly distributed slots to embed the stator winding. Among them, the insulation layer covers the entire stator core and the stator winding. Whether the insulation layer is complete directly determines the service life of the motor. The material used for the rotor is the same as that of the stator. It is also punched and laminated with 0.5 mm thick silicon steel sheets. The outer circle of the silicon steel sheet is punched with evenly distributed holes to accommodate the rotor winding, and an insulation layer is also provided on the surface of the entire rotor.

[0043] Therefore, when installing or removing the motor rotor and stator, the alignment needs to be very precise to ensure that the insulation layer will not be damaged due to the collision and extrusion between the rotor and the stator. Furthermore, during the installation or removal of the motor stator and rotor, it is necessary to minimize the collision and extrusion between the stator and the rotor.

[0044] In the related art, manual disassembly and assembly is usually adopted to disassemble and assemble the rotor or stator of the motor, which has the problems of non-standard operating tools, incompatible fixtures, high labor intensity and high risk factor. In addition, due to the instability of manual disassembly and assembly, it may cause difficulty in aligning the stator and rotor of the motor during assembly, that is, the stator and rotor are not coaxial and there is a certain inclination angle.

[0045] At this time, if the installation or disassembly operation is forced, although the installation or disassembly can be achieved, the damage to the insulation layer and the silicon steel sheets and windings on the stator and rotor is unpredictable, and it may even cause hidden damage inside the motor. The instability of the assembly position between the motor stator and rotor leads to low assembly accuracy of the motor, and even causes failure of the motor during operation, affecting the service life of the motor.

[0046] Therefore, it is urgent to design a tool that can effectively prevent the stator or rotor from tilting during the disassembly and assembly process, thereby reducing the damage to the stator or rotor during the disassembly and assembly process, improving the assembly accuracy of the motor, and thus extending the service life of the motor.

[0047] The following is combined with Figure 1-2 The embodiments of the present application are described in further detail.

[0048] See also Figure 1 , Figure 1 A three-dimensional structural schematic diagram of a disassembly and assembly tool in an embodiment of the present application is shown. An embodiment of the present application provides a disassembly and assembly tool, which is mainly used for disassembling or assembling electric motors for new energy vehicles. The electric motors for new energy vehicles can be either outer rotor motors or inner rotor motors.

[0049] The disassembly and assembly tool comprises a base 1 for providing support force, and the base 1 comprises a supporting portion 11 and a mounting portion 12 connected to each other. In the embodiment of the present application, the supporting portion 11 and the mounting portion 12 are both configured as plate-like structures, and the mounting portion 12 is vertically connected to one side of the supporting portion 11.

[0050] Specifically, the support portion 11 and the mounting portion 12 in the present application can be connected by welding or directly cast by integral molding. In order to ensure the overall structural strength and supporting force of the disassembly and assembly tool, the present application preferably uses integral casting to construct the base 1.

[0051] Continue reading Figure 1 As shown, the disassembly and assembly tool also includes a fixing member 2 and a pushing member 3 arranged on the mounting portion 12, wherein the fixing member 2 is used to fix the motor (not shown) to be disassembled to the above-mentioned mounting portion 12, and the pushing member 3 is configured to be able to extend and retract along the axial direction of the motor, so as to push the stator or rotor of the motor out of the housing of the motor, thereby realizing the disassembly operation of the stator or rotor.

[0052] During the disassembly process, the motor is fixed to the mounting portion 12 by means of the fixing member 2, and the rotor or stator inside the motor can move steadily along the axial direction of the motor under the propulsion of the propulsion member 3, effectively reducing the inclination angle between the rotor and the stator during the disassembly and assembly of the motor, which causes the stator and the rotor to squeeze each other and cause wear, and helps to extend the service life of the motor after disassembly and assembly.

[0053] In some embodiments, the disassembly and assembly tool also includes a supporting member 4 for receiving the ejected stator or rotor. The supporting member 4 is provided to support the stator or rotor of the motor so that after the rotor or stator of the motor is partially separated from the housing, no inclination angle will occur between the stator or rotor remaining in the housing under the influence of gravity, thereby reducing the wear of the stator and the rotor during the disassembly process.

[0054] In an embodiment of the present application, the supporting member 4 includes a receiving groove 411 for accommodating the ejected stator or rotor. The receiving groove 411 extends along the axial direction of the motor and passes through the side wall of the supporting member 4 close to the propulsion member 3. The shape of the receiving groove 411 is consistent with the outer contour of the ejected stator or rotor, so that the stator or rotor can be stably accommodated in the receiving groove 411 and is not prone to displacement, so that the stator or rotor can always move along the axial direction of the motor.

[0055] Specifically, during the disassembly process, the fixing member 2 fixes the motor to be disassembled to the mounting portion 12, and the pushing member 3 pushes the motor stator or rotor along the axial direction of the motor, so that the motor stator or rotor is pushed out of the housing. In the embodiment of the present application, the accommodating groove 411 is located at the top of the supporting member 4. After the stator or rotor is pushed out of the housing by the pushing member 3, the end of the stator or rotor away from the housing enters the accommodating groove 411 from the side of the supporting member 4 close to the pushing member 3. Under the guiding action of the accommodating groove 411, the stator or rotor always moves along the axial direction of the motor, and always maintains a coaxial state with the stator or rotor left in the housing, effectively reducing the inclination angle between the stator and the rotor during the disassembly process, resulting in collision and extrusion between the stator and the rotor, thereby extending the service life of the motor after disassembly.

[0056] Continue reading Figure 1 As shown, in some other embodiments, in order to achieve effective separation between the disassembled stator or rotor and the housing, the supporting member 4 in the embodiment of the present application is configured to be able to move along the axial direction of the motor toward or away from the mounting portion 12. The effective separation here specifies that the stator and the rotor are separated by a certain distance to overcome the attraction between the stator and the rotor.

[0057] In the embodiment of the present application, the supporting member 4 is configured to include a main body 41 and a sliding portion 42 connected to the main body 41, and the supporting portion 11 includes a slide 111 for sliding installation of the sliding portion 42, and the extension direction of the slide 111 is parallel to the axial direction of the motor. Under the guidance of the slide 111, the supporting member 4 can achieve relative displacement with the mounting portion 12 along the axial direction of the motor, thereby realizing the two operation processes of overlapping the supporting member 4 and the shell and supporting the supporting member 4 to support the disassembled stator or rotor away from the shell, thereby ensuring the effective separation between the disassembled stator or rotor and the shell.

[0058] In the embodiment of the present application, the slideway 111 may be a sliding guide rail (not shown), and the sliding guide rail may be any one of a banner type, a multi-point type, or a ball type, as long as it can facilitate the relative displacement between the supporting member 4 and the mounting portion 12, and the structural form thereof is not limited herein. In some other embodiments, the slideway 111 may also be a sliding groove provided on the supporting portion 11, and the sliding portion 42 is slidably installed in the sliding groove, which can also achieve the relative displacement between the supporting member 4 and the mounting portion 12.

[0059] Furthermore, in the embodiment of the present application, the supporting member 4 is configured to be made of non-magnetic material, such as plastic material, specifically any one of PVC, acrylic, and polyester fiber materials, as long as there is no mutual attraction between the selected material and the disassembled rotor.

[0060] See also Figure 1As shown, specifically, the propulsion member 3 includes a propulsion shaft 31 and a crank handle 32. In the embodiment of the present application, the propulsion shaft 31 can be a common screw. The propulsion shaft 31 is configured so that the direction of the central axis coincides with the axial direction of the motor to be disassembled, so as to be used to penetrate into the motor along the axial direction of the motor and push the stator or rotor inside the motor.

[0061] During the actual disassembly process, the propulsion shaft 31 passes through the mounting portion 12 along the axial direction of the motor and is threadedly connected to the mounting portion 12. The crank 32 is installed on the side of the propulsion shaft 31 away from the motor, and the crank 32 is coaxially arranged with the propulsion shaft 31. With the rotation of the crank 32, the propulsion shaft 31 can be pushed along the axial direction of the motor, thereby realizing the pushing operation of the stator or rotor.

[0062] In some embodiments, in order to improve the smoothness of the propulsion shaft 31 during the propulsion process, the crank handle 32 is rotatably installed on the side of the mounting portion 12 facing away from the motor (not shown), thereby reducing the shaking of the propulsion shaft 31 during the propulsion process, causing the stator or rotor abutting against the propulsion shaft 31 to shake, affecting the disassembly stability.

[0063] Continue reading Figure 1 As shown, the fixing member 2 includes at least one pair of clamping portions 21, all of which are connected to the side of the mounting portion 12 facing the motor, and each pair of clamping portions 21 is symmetrically distributed relative to the central axis of the motor, thereby achieving stable clamping of the motor housing to improve the stability of the motor during disassembly and assembly.

[0064] In the embodiment of the present application, only one pair of clamping parts 21 is configured on each disassembly and assembly tool for introduction. It can be understood that in some other embodiments, two or more pairs of clamping parts 21 can be configured on each disassembly and assembly tool to improve the fixing effect of the motor.

[0065] Combination Figure 2 As shown, Figure 2 Shows this application Figure 1 The enlarged view of the middle A part, specifically, the clamping part 21 includes a support rod 213, a pressure head 212 and a clamp 211. The support rod 213 is vertically mounted on the side of the mounting part 12 close to the motor, and the support rod 213 and the mounting part 12 can be connected by welding or integral molding. In the embodiment of the present application, the longitudinal direction of the support rod 213 is parallel to the axial direction of the motor, and the pressure head 212 and the clamp 211 are both movably mounted on the end of the support rod 213 away from the mounting part 12, so as to realize the clamping operation of the motor.

[0066] In the embodiment of the present application, the pressure head 212 is transmission-connected to the clamp 211. The clamp 211 is used to engage with the housing of the motor, thereby fixing the housing. With the rotation of the pressure head 212, the clamp 211 can approach the motor housing, thereby adjusting the clamping angle of the clamping portion 21, generating different clamping forces and clamping angles, so as to adapt to the clamping requirements of motors of different materials and sizes, and expand the scope of application of the disassembly and assembly tool.

[0067] Continue reading Figure 1 As shown, in some embodiments, the fixing member 2 further includes a plurality of interpenetrating portions 22, and all of the interpenetrating portions 22 are connected to the side of the mounting portion 12 close to the motor. Similarly, the interpenetrating portions 22 and the mounting portion 12 can also be connected by welding or integrally formed construction. In the embodiment of the present application, all of the interpenetrating portions 22 are evenly distributed along the circumference of the propulsion shaft 31, so that the support force on the motor is more balanced and stable.

[0068] Specifically, the insertion portion 22 is constructed as a rod-shaped structure, and the extension direction of the insertion portion 22 is parallel to the axial direction of the motor. Before the clamping portion 21 clamps the motor housing, the insertion portion 22 can be pre-inserted into the motor to achieve insertion fixation with the internal structure of the motor, thereby further enhancing the fixing effect of the fixing member 2 on the motor and reducing the shaking of the motor during disassembly.

[0069] For ease of description, in the above embodiments, only the process of disassembling the stator or rotor of the motor is described in detail. It can be understood that in some other embodiments, the disassembly and assembly tool can also be used to assemble the stator or rotor of the motor into the housing, and the installation steps are opposite to the disassembly steps.

[0070] See also Figure 1 and Figure 2 As shown, in some embodiments, the present application also provides a motor disassembly and assembly system, which includes a disassembly and assembly tool as shown in any of the above embodiments and a motor (not shown), and the motor can be any one of an outer rotor motor and an inner rotor motor.

[0071] In the embodiment of the present application, the motor specifically includes a housing, a stator and a rotor. The stator or the rotor can be assembled into the housing with the aid of a disassembly and assembly tool to form a complete motor. The motor can also be disassembled from the housing by the disassembly and assembly tool to realize the disassembly of the stator or the rotor.

[0072] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0073] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
