Description

Technical Field

[0001] This disclosure relates to the field of stator disassembly tooling technology, specifically to a disassembly tooling and a disassembly tooling assembly. Background Technology

[0002] In related technologies, the stator and housing of a motor are usually installed with an interference fit through a heat fitting process. Although this process can achieve a stable connection between the stator and the housing, it is difficult to disassemble the stator inside the housing, and the stator is easily damaged during the disassembly process. Utility Model Content

[0003] This disclosure provides a disassembly fixture and a disassembly fixture assembly to at least partially overcome the problems existing in the related art.

[0004] To achieve the above objectives, according to a first aspect of this disclosure, a disassembly fixture is provided, the disassembly fixture including a support frame and a first buffer member;

[0005] The support frame includes a base and a first movable member, the first movable member being movably connected to the base in the vertical direction, the first movable member being used to support the stator of the motor, and the base being used to be installed to the stator retraction component;

[0006] The first buffer is disposed between the first movable part and the base, and is used to provide cushioning to the first movable part.

[0007] In summary, by using the disassembly fixture provided in this application, the disassembly fixture can automatically disassemble the stator inside the housing with the cooperation of an electromagnetic induction device or a heating device such as an oven. This helps to simplify the disassembly difficulty of the stator inside the housing and improve the disassembly efficiency of the stator.

[0008] In addition, during the disassembly process, the support and buffering effect of the first moving part and the first buffer part can also buffer and reduce the movement of the stator, which helps to avoid the stator from colliding with other parts or devices. The stator is safer during disassembly and is not easily damaged.

[0009] In some possible implementations, the support frame further includes a second movable member and a second buffer member, the second movable member being disposed between the first movable member and the base;

[0010] The first movable component is movably connected to the second movable component in the vertical direction, and the second movable component is movably connected to the base in the vertical direction.

[0011] The first buffer is disposed between the first movable member and the second movable member, and the second buffer is disposed between the second movable member and the base.

[0012] By setting a second buffer on top of the first buffer, the two buffers (i.e., the first buffer and the second buffer) work together to buffer and dampen the stator. This helps to further reduce the impact and / or bumps on the stator during movement, and thus further improves the protection of the stator during disassembly.

[0013] Furthermore, by setting two movable parts (i.e., the first movable part and the second movable part) within the disassembly fixture, the two movable parts can move downward simultaneously under the gravity of the stator. The displacements of the two movable parts are superimposed, allowing the stator to have a large displacement while allowing the two movable parts to have small displacements themselves. This enables the stator to be removed as a whole from the housing. The two movable parts with small displacements do not need to reserve a large space to disassemble the stator, which helps to reduce the size of the entire disassembly fixture and makes it easier to arrange in a space with limited dimensions.

[0014] In some possible implementations, one of the first movable member and the second movable member is provided with a first guide member, and the other is provided with a first guide engagement portion, wherein the first guide member is movably engaged with the first guide engagement portion along the vertical direction; and / or,

[0015] The second movable component and the base are provided with a second guide component, and the other is provided with a second guide engagement part. The second guide component is movably engaged with the second guide engagement part in the vertical direction.

[0016] The first guide member and the first guide mating part cooperate with each other, and / or the second guide member and the second guide mating part cooperate with each other, so as to guide and limit the movement of the first movable member and / or the second movable member. In this way, when the first movable member and the second movable member move downward under the gravity of the stator, the first movable member and / or the second movable member are not prone to deviation. This is beneficial to make the stator move along a preset trajectory during disassembly (for example, it can move in a vertically downward direction and away from the housing), preventing it from deviating or shaking, thereby further improving the stability and safety of the stator during disassembly.

[0017] In some possible implementations, the first guide member includes a first guide rod disposed on the first movable member, and the first guide mating portion includes a first guide hole formed on the second movable member, the first guide rod being movably mated with the first guide hole along the vertical direction; and / or,

[0018] The second guide member includes a second guide rod, which is disposed on the second movable member. The second guide mating part includes a second guide hole formed on the base, and the second guide rod is movably mated with the second guide hole along the vertical direction.

[0019] Thus, when the first movable component moves downward under the weight of the stator, the wall of the first guide hole opened on the second movable component can abut against the outer circumferential surface of the first guide rod, thereby limiting the radial movement of the first guide rod, and further guiding and limiting the movement of the first movable component.

[0020] Furthermore, when the second movable component moves downward under the weight of the stator, the wall of the second guide hole on the base can also abut against the outer circumferential surface of the first guide rod, thereby limiting the radial movement of the second guide rod, and thus guiding and limiting the movement of the second movable component.

[0021] In some possible implementations, the base is also provided with a clearance hole, which is disposed opposite to the first guide rod in the vertical direction;

[0022] The clearance hole is used for the first guide rod to pass through.

[0023] By providing clearance holes on the base, when the first movable member moves toward the direction closer to the base (i.e. downward) under the gravity of the stator, the base located below the first movable member will not interfere with the movement of the first guide rod. The first guide rod can at least partially pass through the clearance holes and continue to move downward. This is beneficial to increasing the range of motion of the first movable member. The first movable member with a larger range of motion can allow the stator to undergo larger displacement, which is beneficial to the overall removal of the stator from the housing.

[0024] In some possible implementations, the first movable member is constructed as a first annular member, and the number of the first guide rods is plurality of them, with the plurality of first guide rods arranged at circumferential intervals along the first annular member; and / or,

[0025] The second movable component is constructed as a second annular component, and there are multiple second guide rods, which are arranged at intervals along the circumference of the second annular component.

[0026] The first movable part, which is constructed as a ring, is adapted to the shape of the stator. The contact area between the first movable part and the stator is large, and the first movable part provides good support for the stator.

[0027] Furthermore, the second movable part, which is constructed as a ring, can also be adapted to the shape of the first movable part, which facilitates the design, production, and manufacturing of the entire disassembly fixture. This can effectively avoid the inconvenience of processing irregularly shaped disassembly fixtures and also improve the aesthetics of the entire disassembly fixture.

[0028] Furthermore, by setting multiple first guide rods and / or multiple second guide rods on the first movable part and the second movable part respectively, and by having multiple first guide rods and / or multiple second guide rods cooperate with each other, it is also beneficial to further improve the guiding and limiting effect on the first movable part and the second movable part.

[0029] In some possible implementations, the first movable member is an annular member, the second movable member is an annular member, and the outer diameter of the second movable member is larger than the outer diameter of the first movable member;

[0030] Along the radial direction of the first movable member or the second movable member, the first guide rod is located inside the second guide rod.

[0031] By making the outer diameter of the second movable member larger than that of the first movable member, and by placing the second guide rod outside the first guide rod, the first movable member, the first guide rod, the second movable member, and the second guide rod can be constructed into a pyramid-like structure. The first movable member, the first guide rod, the second movable member, and the second guide rod, which form a pyramid structure, have higher stability, which is beneficial to further improving the support effect on the stator.

[0032] In some possible implementations, the first buffer includes a first spring sleeved on the first guide rod, with its two ends respectively used to abut against the first movable member and the second movable member; and / or,

[0033] The second buffer includes a second spring, which is sleeved on the second guide rod, and the two ends of the second spring are respectively used to abut against the second movable member and the base.

[0034] Thus, when the first and second movable parts move downwards under the weight of the stator, the first spring between the first movable part and the base, and the second spring between the second movable part and the base, are compressed and can exert opposite forces on the first and second movable parts, thereby buffering and damping the movement of the stator.

[0035] In some possible implementations, the first guide member includes a first slider disposed on the first movable member, and the first guide mating part includes a first groove disposed in the second movable member, the first groove extending along the vertical direction, and the first slider movably mating with the first groove along the vertical direction.

[0036] The second guide member includes a second slider, which is disposed on the second movable member. The second guide mating part includes a second slide groove disposed within the second movable member. The second slide groove extends along the vertical direction, and the second slider is movably mated with the second slide groove along the vertical direction.

[0037] In this way, the first sliding member and the first sliding groove, the second sliding member and the second sliding groove cooperate with each other to support and guide the first movable member and the second movable member.

[0038] According to a second aspect of this disclosure, a disassembly tooling assembly is provided, including a stator recovery component and the disassembly tooling as described above;

[0039] The stator recovery component includes a body and a tray disposed above the body, with a receiving cavity between the body and the tray for accommodating the stator;

[0040] The support plate is adapted to support the motor housing;

[0041] The tray has a disassembly hole communicating with the receiving cavity, and the diameter of the disassembly hole is larger than the diameter of the stator of the motor;

[0042] The disassembly fixture is disposed in the receiving cavity, and at least a portion of the first movable member can pass through the disassembly hole and abut against the stator.

[0043] Thus, when the stator of the motor needs to be disassembled, the operator can place the motor to be disassembled on the tray of the stator recycling parts, fix the motor housing, and align the stator of the motor with the disassembly hole on the tray. At the same time, the operator can place the disassembly fixture in the receiving cavity and abut the first moving part of the disassembly fixture against the stator. Then, the assembled motor and the disassembly fixture assembly can be placed together in an oven or electromagnetic generator. The housing and stator are heated by the oven or electromagnetic induction. When there is a certain gap between the housing and the stator, the stator can move downward under the action of gravity and pass through the disassembly hole, thereby realizing the separation between the stator and the housing. The disassembly of the stator inside the housing is relatively simple.

[0044] In addition, the disassembly fixture can also support, buffer, and reduce vibration of the stator during the disassembly process, effectively preventing damage to the stator during disassembly.

[0045] In some possible implementations, the diameter of the disassembly hole is smaller than the diameter of the motor housing.

[0046] By designing the diameter of the disassembly hole to be larger than the diameter of the stator and smaller than the diameter of the motor housing, when the stator needs to be disassembled, the motor housing can be fixed on the tray by the abutment of the tray plate, and will not move with the stator. The housing and stator, which have relative movement, can be separated from each other, thereby enabling the disassembly of the stator inside the housing.

[0047] In some possible implementations, the stator recovery component further includes a support member, the lower end of which is connected to the bottom wall of the receiving cavity;

[0048] The upper end of the support member is used to support the base of the disassembly fixture, so that there is a gap between the base and the bottom wall.

[0049] Because the support allows for a gap between the base of the disassembly fixture and the bottom wall of the receiving cavity, even if the disassembly fixture moves downward under the action of the stator, the bottom wall of the receiving cavity will not interfere with the disassembly fixture, allowing the disassembly fixture to move normally and thus enabling the disassembly of the stator within the housing.

[0050] In some possible implementations, there are multiple supports, which are spaced apart on the bottom wall of the receiving cavity.

[0051] Multiple support members spaced apart on the bottom wall of the receiving cavity can simultaneously support the disassembly fixture, making the installation of the disassembly fixture in the receiving cavity more stable and less prone to shaking, which helps to further improve the stability of the stator during the disassembly process.

[0052] In some possible implementations, the body is constructed as a frame structure.

[0053] The frame structure allows the main body to have sufficient strength to support the motor while maintaining a light weight. This results in a lighter overall weight for the stator components, and fewer lightweight stator components are needed. This reduces production and manufacturing costs and also facilitates handling.

Detailed Implementation

[0067] Embodiments of this disclosure will now be described in more detail with reference to the accompanying drawings. While some embodiments of this disclosure are shown in the drawings, it should be understood that this disclosure can be implemented in various forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of this disclosure. It should be understood that the accompanying drawings and embodiments of this disclosure are for illustrative purposes only and are not intended to limit the scope of protection of this disclosure.

[0068] The term "comprising" and its variations as used herein are open-ended inclusions, meaning "including but not limited to". The term "based on" means "at least partially based on". The term "one embodiment" means "at least one embodiment"; the term "another embodiment" means "at least one additional embodiment". Definitions of other terms will be given in the following description.

[0069] It should be noted that the concepts of "first" and "second" mentioned in this disclosure are used only to distinguish different devices, modules or units, and are not used to limit the order of functions performed by these devices, modules or units or their interdependencies.

[0070] It should be noted that the terms "a" and "a plurality of" used in this disclosure are illustrative rather than restrictive, and those skilled in the art should understand that, unless otherwise expressly indicated in the context, they should be understood as "one or more".

[0071] In this disclosure, it should be understood that directional terms such as "up and down" are defined based on the orientation of the accompanying drawings and are used solely for the convenience of describing the disclosure and simplifying the description. They do not indicate or imply that the device or component referred to must have a specific orientation, or a specific orientational structure and operation, and therefore should not be construed as a limitation of this disclosure. For example, the up and down direction can be the vertical direction, i.e., the direction of gravity; see reference [link to relevant documentation] for details. Figure 1 , Figure 7 as well as Figure 8 As shown.

[0072] In the description of this disclosure, it should also be noted that, unless otherwise expressly specified and limited, the terms "set up," "connect," "link," and "install" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this disclosure according to the specific circumstances.

[0073] As mentioned above, the connection between the stator and the housing installed in the housing by the heat fitting process is relatively stable. However, if the motor malfunctions during use, or when it is necessary to determine the quality of the motor, that is, to analyze the problem or determine the quality of the motor, the stator of the motor needs to be removed. The interference fit between the stator and the housing is tight, making disassembly difficult and easily damaging to the stator during disassembly.

[0074] For example, when removing the stator by breaking the casing, the casing will be damaged; moreover, the stator is easily scratched during the cutting process. Alternatively, when removing the stator by heating, the stator is prone to falling under gravity and hitting the tray used for stator recycling, which can easily render the stator unusable due to the impact.

[0075] In view of this, such as Figures 1 to 3 As shown, according to a first aspect of this disclosure, a disassembly fixture 10 is provided. The disassembly fixture 10 includes a support frame 1 and a first buffer member 2. The support frame 1 includes a base 11 and a first movable member 12. The first movable member 12 is movably connected to the base 11 in the vertical direction. The first movable member 12 is used to support the stator 9 of the motor 30. The base 11 is used to install to the stator retraction member 20. The first buffer member 2 is disposed between the first movable member 12 and the base 11 and is used to provide cushioning to the first movable member 12.

[0076] When the disassembly fixture 10 provided in this disclosure is used to disassemble the stator 9, the disassembly fixture 10 can be placed below the stator 9, and the first movable member 12 can be supported on the stator 9. At this time, the housing 8 and the stator 9 can be heated by means of heating, such as electromagnetic induction or an oven 40. Due to the difference in material and structure between the housing 8 and the stator 9, the housing 8 will have a faster expansion rate and expansion size. As the heating process continues, a certain gap will gradually be generated between the housing 8 and the stator 9. When this gap is formed, the stator 9 can press the first movable member 12 downward under the action of gravity, and The first movable part 12 is moved downward, thereby separating the stator 9 from the housing 8. During this process, the first buffer 2, which is located between the first movable part 12 and the base 11, can also buffer and dampen the movement of the first movable part 12 and the stator 9, which helps to remove the stator 9 smoothly from the housing 8. This helps to avoid the stator 9 falling due to impact or excessive vibration, or being bumped during disassembly. The disassembly of the stator 9 in the housing 8 is relatively simple and is not prone to collision with other components or devices (such as the stator recovery components mentioned above, such as trays).

[0077] In summary, by using the disassembly fixture 10 provided in this application, the disassembly fixture 10 can automatically disassemble the stator 9 in the housing 8 with the cooperation of an electromagnetic induction device or a heating device such as an oven 40. This helps to simplify the disassembly difficulty of the stator 9 in the housing 8 and improve the disassembly efficiency of the stator 9.

[0078] In addition, during the disassembly process, the first movable part 12 and the first buffer part 2 provide support and cushioning, which can also buffer and dampen the movement of the stator 9. This helps to avoid the stator 9 from colliding with other parts or devices. The stator 9 is safer during disassembly and is not easily damaged.

[0079] Compared to related technologies that involve removing the stator 9 by breaking the housing 8 or by direct heating, the disassembly fixture 10 provided in this application does not require breaking the housing 8, which can effectively simplify the disassembly of the stator 9, improve the disassembly efficiency of the stator 9, and also improve the safety of the stator 9 during disassembly, effectively preventing damage to the stator 9 during the disassembly process. In addition, compared to the implementation method that requires manual removal of the stator 9 by using clamps after heating the housing 8 and the stator 9, it can also avoid the situation where operators are easily burned due to manual operation.

[0080] To further prevent the stator 9 from falling off the first moving part 12 during disassembly, in some possible implementations, such as Figure 1 As shown, the first movable member 12 is also provided with a flange 121, which extends in the vertical direction away from the first movable member 12. By providing the flange 121 on the first movable member 12, the flange 121 can be fitted onto the outer peripheral surface of the stator 9, thereby blocking the radial movement of the stator 9. This helps to further prevent the stator 9 from falling off the first movable member 12 during disassembly, thus avoiding damage to the stator 9.

[0081] To improve the support and buffering performance of the disassembly fixture 10 against the stator 9, in some possible implementations, such as Figure 1 , Figure 7 and Figure 8 As shown, the support frame 1 may further include a second movable member 13 and a second buffer member 3. The second movable member 13 is disposed between the first movable member 12 and the base 11. The first movable member 12 is movably connected to the second movable member 13 in the vertical direction, and the second movable member 13 is movably connected to the base 11 in the vertical direction. The first buffer member 2 is disposed between the first movable member 12 and the second movable member 13, and the second buffer member 3 is disposed between the second movable member 13 and the base 11.

[0082] By setting a second buffer 3 on the basis of the first buffer 2, the two buffers (i.e. the first buffer 2 and the second buffer 3) cooperate with each other to buffer and dampen the stator 9. This helps to further reduce the impact and / or bumps on the stator 9 during movement, and thus further improves the protection effect of the stator 9 during disassembly.

[0083] Furthermore, by setting two movable parts (i.e., the first movable part 12 and the second movable part 13) in the disassembly fixture 10, the two movable parts can move downward simultaneously under the gravity of the stator 9. The displacements of the two movable parts are superimposed, which allows the stator 9 to have a large displacement while allowing the two movable parts to have small displacements themselves. This enables the stator 9 to be removed as a whole from the housing 8. The two movable parts with small displacements do not need to reserve a large space to disassemble the stator 9. This helps to reduce the size of the entire disassembly fixture 10 and makes it easier to arrange in a space with limited size.

[0084] To further prevent the stator 9 from shaking during disassembly, thus avoiding collisions, in some possible implementations, such as... Figures 1 to 3 As shown, one of the first movable member 12 and the second movable member 13 is provided with a first guide member 14, and the other is provided with a first guide mating part 15. The first guide member 14 is movably mated with the first guide mating part 15 in the vertical direction. And / or, one of the second movable member 13 and the base 11 is provided with a second guide member 16, and the other is provided with a second guide mating part 17. The second guide member 16 is movably mated with the second guide mating part 17 in the vertical direction.

[0085] The first guide member 14 and the first guide mating part 15 cooperate with each other, and / or the second guide member 16 and the second guide mating part 17 cooperate with each other, which can guide and limit the movement of the first movable member 12 and / or the second movable member 13. Thus, when the first movable member 12 and the second movable member 13 move downward under the gravity of the stator 9, the first movable member 12 and / or the second movable member 13 are less likely to deviate. This is beneficial to make the stator 9 move along a preset trajectory during disassembly (for example, it can move vertically downward and away from the housing 8), preventing it from deviating or shaking, thereby further improving the stability and safety of the stator 9 during disassembly.

[0086] This disclosure does not limit the specific type or structure of the first guide member 14, the first guide mating part 15, the second guide member 16, and the second guide mating part 17. As one embodiment of this disclosure, such as... Figures 1 to 3As shown, the first guide member 14 includes a first guide rod 141, which is disposed on the first movable member 12. The first guide mating part 15 includes a first guide hole 131 opened on the second movable member 13. The first guide rod 141 is movably mated with the first guide hole 131 in the vertical direction. And / or, the second guide member 16 includes a second guide rod 161, which is disposed on the second movable member 13. The second guide mating part 17 includes a second guide hole 112 opened on the base 11. The second guide rod 161 is movably mated with the second guide hole 112 in the vertical direction.

[0087] Thus, when the first movable member 12 moves downward under the gravity of the stator 9, the wall of the first guide hole 131 opened on the second movable member 13 can abut against the outer peripheral surface of the first guide rod 141, thereby limiting the radial movement of the first guide rod 141, and further guiding and limiting the movement of the first movable member 12.

[0088] Furthermore, when the second movable member 13 moves downward under the gravity of the stator 9, the wall of the second guide hole 112 opened on the base 11 can also abut against the outer peripheral surface of the first guide rod 141, thereby limiting the radial movement of the second guide rod 161, and thus guiding and limiting the movement of the second movable member 13.

[0089] In order to enable the first movable member 12 to have a large range of motion, in some possible embodiments, such as Figure 3 As shown, the base 11 is also provided with a clearance hole 111. Along the vertical direction, the clearance hole 111 is arranged opposite to the first guide rod 141, and the clearance hole 111 is used for the first guide rod 141 to pass through.

[0090] By providing clearance holes 111 on the base 11, when the first movable member 12 moves toward the base 11 (i.e. downward) under the gravity of the stator 9, the base 11 located below the first movable member 12 will not interfere with the movement of the first guide rod 141. The first guide rod 141 can at least partially pass through the clearance holes 111 and continue to move downward, which is beneficial to increasing the range of motion of the first movable member 12. The first movable member 12 with a larger range of motion can allow the stator 9 to undergo a larger displacement, which is beneficial to the overall removal of the stator 9 from the housing 8.

[0091] In some possible implementations, such as Figure 1 , Figure 7 and Figure 8As shown, the first movable member 12 is constructed as a first annular member, and there are multiple first guide rods 141, which are arranged at intervals along the circumference of the first annular member. And / or, the second movable member 13 is constructed as a second annular member, and there are multiple second guide rods 161, which are arranged at intervals along the circumference of the second annular member.

[0092] The first movable member 12, which is constructed as a ring, is adapted to the shape of the stator 9. The contact area between the first movable member 12 and the stator 9 is large, and the first movable member 12 provides good support for the stator 9.

[0093] Furthermore, the second movable part 13, which is constructed as a ring, can also be adapted to the shape of the first movable part 12, which facilitates the overall design, production and manufacturing of the disassembly fixture 10. It can effectively avoid the inconvenience of processing irregularly shaped disassembly fixtures 10, and also improve the aesthetics of the entire disassembly fixture 10.

[0094] Furthermore, by providing multiple first guide rods 141 and / or multiple second guide rods 161 on the first movable member 12 and the second movable member 13 respectively, the multiple first guide rods 141 and / or multiple second guide rods 161 cooperate with each other, which is conducive to further improving the guiding and limiting effect on the first movable member 12 and the second movable member 13.

[0095] To further improve the support effect on stator 9, in some possible implementations, such as Figure 1 , Figure 7 and Figure 8 As shown, the first movable part 12 is a ring-shaped part, the second movable part 13 is a ring-shaped part, and the outer diameter of the second movable part 13 is larger than the outer diameter of the first movable part 12. Along the radial direction of the first movable part 12 or the second movable part 13, the first guide rod 141 is located inside the second guide rod 161.

[0096] By making the outer diameter of the second movable member 13 larger than the outer diameter of the first movable member 12, and by placing the second guide rod 161 outside the first guide rod 141, the first movable member 12, the first guide rod 141, the second movable member 13, and the second guide rod 161 can be constructed into a pyramid-like structure. The stability of the first movable member 12, the first guide rod 141, the second movable member 13, and the second guide rod 161, which form a pyramid structure, is higher, which is beneficial to further improving the support effect on the stator 9.

[0097] This disclosure does not limit the specific types of the first buffer 2 and the second buffer 3; the first buffer 2 and the second buffer 3 can be any buffer suitable for being disposed within the disassembly fixture 10. As one embodiment of this disclosure, for example... Figure 1As shown, the first buffer 2 may include a first spring 21, which is sleeved on the first guide rod 141. The two ends of the first spring 21 are respectively used to abut against the first movable member 12 and the second movable member 13. And / or, the second buffer 3 may include a second spring 31, which is sleeved on the second guide rod 161. The two ends of the second spring 31 are respectively used to abut against the second movable member 13 and the second movable member 13.

[0098] Thus, when the first movable member 12 and the second movable member 13 move downward under the weight of the stator 9, the first spring 21 between the first movable member 12 and the base 11, and the second spring 31 between the second movable member 13 and the base 11 are compressed, which can apply opposite forces to the first movable member 12 and the second movable member 13, thereby buffering and damping the movement of the stator 9.

[0099] To prevent damage to the first spring 21 and the second spring 31 during heating of the housing 8 and the stator 9, in some possible embodiments, the first spring 21 and the second spring 31 are supported by high-temperature resistant springs. Thus, when the disassembly fixture 10 is placed in the oven 40 for heating, the elastic modulus and shear modulus of the first spring 21 and the second spring 31 supported by high-temperature resistant springs will not decrease excessively, and they can maintain good cushioning performance even under high-temperature conditions.

[0100] In order for the first spring 21 and the second spring 31 to meet the buffering requirements during the disassembly of the stator 9, in some possible embodiments, the specifications of the first spring 21 and the second spring 31 are as follows: the wire diameter of the spring is 2mm, the outer diameter is 20mm, the length is 180mm, and it is made of 631 stainless steel.

[0101] The first spring 21 and the second spring 31, made of 631 stainless steel, have high elastic deformation capacity and fatigue resistance, which can provide a good buffering effect for the stator 9, while also ensuring a long service life.

[0102] As other embodiments of this disclosure, the first buffer 2 and the second buffer 3 may also be constructed as elastic rubber, air springs, etc., and this disclosure does not limit them.

[0103] It should be noted that in the disassembly fixture 10 provided in this disclosure, the first guide member 14, the first guide mating part 15, the second guide member 16, and the second guide mating part 17 are not limited to the guide rod and guide hole mentioned above.

[0104] As another embodiment of this disclosure, the first guide member 14 may further include a second slider disposed on the first movable member 12, the first guide mating part 15 includes a first slide groove disposed in the second movable member 13, the first slide groove extends in the vertical direction, and the second slider is movably mated with the first slide groove in the vertical direction, and / or, the second guide member 16 may further include a second slider disposed on the second movable member 13, the second guide mating part 17 includes a second slide groove disposed in the second movable member 13, the second slide groove extends in the vertical direction, and the second slider is movably mated with the second slide groove in the vertical direction.

[0105] In this way, the first sliding member and the first sliding groove, the second sliding member and the second sliding groove cooperate with each other to support and guide the first movable member 12 and the second movable member 13.

[0106] According to the second aspect of this disclosure, such as Figures 4 to 9 As shown, a disassembly tooling assembly 100 is provided, including a stator recovery component 20 and a disassembly tooling 10 as described above. The stator recovery component 20 includes a body 4 and a support plate 5 disposed above the body 4. There is a receiving cavity 6 between the body 4 and the support plate 5 for accommodating a stator 9. The support plate 5 is adapted to support the housing 8 of the motor 30. A disassembly hole 51 communicating with the receiving cavity 6 is provided on the support plate 5. The diameter of the disassembly hole 51 is larger than the diameter of the stator 9 of the motor 30. The disassembly tooling 10 is disposed in the receiving cavity 6. At least a portion of the first movable member 12 can pass through the disassembly hole 51 and abut against the stator 9.

[0107] Thus, when the stator 9 of the motor needs to be disassembled, the operator can place the motor 30 to be disassembled on the tray 5 of the stator recycling component 20, fix the housing 8 of the motor 30, and align the stator 9 of the motor 30 with the disassembly hole 51 on the tray. At the same time, the operator can place the disassembly fixture 10 in the receiving cavity 6 and abut the first movable part 12 of the disassembly fixture 10 against the stator 9. Then, the assembled motor 30 and the disassembly fixture assembly 100 can be placed together in the oven 40 or the electromagnetic generator. The housing 8 and the stator 9 are heated by the oven 40 or electromagnetic induction. When there is a certain gap between the housing 8 and the stator 9, the stator 9 can move downward under the action of gravity and pass through the disassembly hole 51, thereby realizing the separation between the stator 9 and the housing 8. The disassembly of the stator 9 in the housing 8 is relatively simple.

[0108] In addition, the disassembly fixture 10 can also support, buffer and dampen the stator 9 during the disassembly process, which can effectively prevent the stator 9 from being damaged during the disassembly process.

[0109] In the disassembly tooling assembly 100 provided in this disclosure, the housing 8 of the motor 30 can be fixed to the tray 5 of the stator recovery component 20 in any suitable manner, and this disclosure does not limit this.

[0110] As one embodiment of this disclosure, such as Figure 4 As shown, the diameter of the disassembly hole 51 is smaller than the diameter of the housing 8 of the motor 30.

[0111] By designing the diameter of the disassembly hole 51 to be larger than the diameter of the stator 9 and the diameter of the disassembly hole 51 to be smaller than the diameter of the housing 8 of the motor 30, when the stator 9 needs to be disassembled, the housing 8 of the motor 30 can be fixed on the tray under the action of the support plate 5, and will not move with the stator 9. The housing 8 and the stator 9, which have relative movement, can be separated from each other, thereby enabling the disassembly of the stator 9 within the housing 8.

[0112] In other embodiments of this disclosure, the diameter of the disassembly hole 51 may also be larger than the diameter of the housing 8 of the motor 30, and a clamp may be provided on the support plate 5 for fixing the housing 8 of the motor 30.

[0113] Thus, the clamps can also be used to fix the motor housing 8 of the stator 9 during the disassembly process, thereby enabling the disassembly of the stator 9 within the housing 8.

[0114] In some possible implementations, such as Figures 4 to 8 As shown, the stator recovery component 20 may also include a support component 7, the lower end of which is connected to the bottom wall of the receiving cavity 6, and the upper end of which is used to support the base 11 of the disassembly fixture 10 so that there is a gap between the base 11 and the bottom wall.

[0115] Since the support member 7 allows for a gap between the base 11 of the disassembly fixture 10 and the bottom wall of the receiving cavity 6, even if the disassembly fixture 10 moves downward under the action of the stator 9, the bottom wall of the receiving cavity 6 will not interfere with the disassembly fixture 10, and the disassembly fixture 10 can move normally, thereby realizing the disassembly of the stator 9 in the housing 8.

[0116] For example, in the embodiment where the disassembly fixture 10 includes a second movable member 13, a second guide rod 161 is provided on the second movable member 13, a second guide hole 112 is provided on the base 11, and the second guide rod 161 is movably engaged with the second guide hole 112 in the vertical direction, even if the second movable member 13 moves downward due to the action of the stator 9, the second guide rod 161 connected to the second movable member 13 will not contact the bottom wall of the receiving cavity 6, and the second movable member 13 can move downward normally, thereby realizing the disassembly of the stator 9 in the housing 8.

[0117] In the disassembly tooling assembly 100 provided in this disclosure, the number of support members 7 can be one or more; this disclosure does not limit this. As one embodiment of this disclosure, such as… Figures 4 to 8 As shown, there can be multiple support members 7, which are spaced apart on the bottom wall of the receiving cavity 6. For example, multiple support members 7 can be spaced apart along the width and / or length direction of the body 4.

[0118] Multiple support members 7 spaced apart on the bottom wall of the receiving cavity 6 can simultaneously support the disassembly fixture 10. The disassembly fixture 10 is more stable in the receiving cavity 6 and is not easy to shake, which helps to further improve the stability of the stator 9 during the disassembly process.

[0119] This disclosure does not limit the specific structure of the stator recovery component 20; in some possible embodiments, such as Figures 4 to 9 As shown, the main body 4 can be constructed as a frame structure.

[0120] The frame structure of the main body 4 can have a certain strength and meet the support requirements of the motor 30, while having a light weight. This is beneficial to make the stator recovery component 20 have a lighter overall weight. Since the stator recovery component 20 is lighter, the amount of it used is less. On the one hand, it helps to reduce the production and manufacturing cost of the stator recovery component 20; on the other hand, it also makes it easier to handle.

[0121] It should be noted that, for the embodiment in which the body 4 is constructed as a frame structure, the bottom wall of the receiving cavity 6 refers to the surface of the lower end of the frame structure away from the support plate 5, that is, the surface of the frame structure closer to the ground.

[0122] Reference Figure 4 as well as Figures 7 to 9 As shown, when it is necessary to perform problem analysis or quality assessment on the motor 30, and the stator 9 and housing 8 are disassembled by heating in the oven 40, the stator 9 disassembly assembly provided in this disclosure can be used in the following ways:

[0123] First, such as Figure 4 As shown, the operator can place the motor 30 to be disassembled on the tray 5 of the stator recycling part 20, and align the stator 9 of the motor 30 with the disassembly hole 51 on the tray. At the same time, the operator can place the disassembly tool 10 in the receiving cavity 6 and abut the first movable part 12 of the disassembly tool 10 against the stator 9.

[0124] like Figure 9As shown, after the motor 30 to be disassembled and the disassembly tooling assembly 100 are assembled, the operator can place the disassembly tooling assembly 100 and the motor 30 on the mobile trolley 50. This makes it easy to send the disassembly tooling assembly and the motor 30 into the oven 40 or take them out of the oven 40.

[0125] like Figure 7 and Figure 8 As shown, after the disassembly tooling assembly 100 and motor 30 are sent into the oven 40 by the moving trolley 50, the door of the oven 40 can be closed, and the housing 8 and stator 9 are heated by the oven 40. At this time, due to the difference in material and structure between the housing 8 and the stator 9, the housing 8 will have a faster expansion speed and expansion size. As the heating process continues, a certain gap will gradually be generated between the housing 8 and the stator 9. When this gap is formed, without human or mechanical intervention, the stator 9 can squeeze the first movable part 12 and the second movable part 13 under the action of gravity, and cause the first movable part 12 and the second movable part 13 to move downward. During this process, the first buffer 2 and the second buffer 3 can buffer and dampen the movement of the first movable part 12 and the second movable part 13 until the stator 9 is completely detached from the housing 8.

[0126] Once the stator 9 is completely detached from the housing 8, the oven door of the oven 40 can be opened. The disassembly tooling assembly 100 and the separated housing 8 and stator 9 can be removed by the moving trolley 50, thereby enabling problem analysis and quality judgment of the motor 30. The disassembly between the stator 9 and the housing 8 is relatively simple, and the stator 9 is not easily damaged during the disassembly process.

[0127] The preferred embodiments of this disclosure have been described in detail above with reference to the accompanying drawings. However, this disclosure is not limited to the specific details of the above embodiments. Within the scope of the technical concept of this disclosure, various simple modifications can be made to the technical solutions of this disclosure, and these simple modifications all fall within the protection scope of this disclosure.

[0128] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, this disclosure will not describe the various possible combinations separately.

[0129] Furthermore, various different embodiments of this disclosure can be combined in any way, as long as they do not violate the spirit of this disclosure, they should also be regarded as the content disclosed in this disclosure.
