Description

Technical Field

[0001] This invention belongs to the field of motor design technology, specifically relating to a motor and a motor end cover disassembly device and disassembly method used in conjunction with it. Background Technology

[0002] As the product categories in the new energy sector continue to expand, the number of motor products has also increased. Motor verification and maintenance often require disassembly. However, due to a lack of corresponding structural design, current motor disassembly largely relies on manual methods. In practice, operators hold the motor in place while using tools such as pestles and hammers to repeatedly tap along the edge of the motor end cover until it loosens from the stator. The end cover is then manually removed. This manual disassembly method, due to uneven tapping force and complex steps, results in low efficiency and a high scrap rate. This is especially true for encapsulated motors (also known as plastic-encapsulated motors), where repeated tapping with varying force can easily cause breakage during disassembly. Summary of the Invention

[0003] Therefore, the present invention provides an electric motor and a motor end cover disassembly device and disassembly method used therewith, which can overcome the shortcomings of related technologies where the lack of necessary structural matching of the motor makes the disassembly of the motor end cover require manual methods, resulting in low disassembly efficiency and high disassembly scrap rate. In particular, manual disassembly of motors with plastic-encapsulated structures is prone to causing the motor to break.

[0004] To address the aforementioned problems, the present invention provides an electric motor, comprising a motor housing cylinder and a motor end cap assembled at the opening of the motor housing cylinder. The outer wall of the motor housing cylinder is provided with a plurality of motor fixing slots and a plurality of disassembly slots, wherein each of the motor fixing slots and each of the disassembly slots is spaced apart around the central axis of the motor housing cylinder, and each of the disassembly slots extends through both ends of the motor housing cylinder along the axial direction of the motor housing cylinder and is projected along the axial direction of the motor housing cylinder. The motor end cap has a portion located within each of the disassembly slots.

[0005] In some embodiments, a plurality of motor mounting feet are formed on the outer wall of the motor housing, and each of the motor mounting feet is spaced apart around the central axis of the motor housing, and each of the disassembly slots is located between two adjacent motor mounting feet.

[0006] In some embodiments, along the axial projection of the motor housing cylinder, the positions of each motor fixing slot and each motor mounting foot correspond one-to-one and are respectively within the projection range of the motor mounting foot.

[0007] In some embodiments, the motor is a plastic-encapsulated motor; and / or, the motor housing has a first opening, a first annular platform on the end face of the first opening, and a second annular platform on the motor end cap, the second annular platform being fitted onto the radial outer wall of the first annular platform to achieve an interference fit between the motor end cap and the motor housing.

[0008] In some embodiments, the motor housing cylinder is provided with a cable outlet clamp, which is located between two adjacent motor mounting feet, and two disassembly slots are provided in the area between the two motor mounting feet where the cable outlet clamp is located, with the two disassembly slots located on both sides of the cable outlet clamp.

[0009] The present invention also provides a motor end cover disassembly device for use with the aforementioned motor, including a motor fixing component and an end cover pushing component. The motor fixing component has multiple barrel positioning components, and each barrel positioning component has a barrel positioning block that can be driven to be inserted into each motor fixing slot in a radial direction of the motor. The end cover pushing component includes a pushing component and a pressure member that are arranged in a corresponding manner to each disassembly slot. The pressure member can apply force to each pushing component along the axial direction of the motor.

[0010] In some embodiments, the motor end cover disassembly device further includes an end cover heating component, which heats the motor end cover.

[0011] In some embodiments, the motor fixing component further includes a fixing worktable, on which a through hole is formed, and each of the barrel positioning components is arranged at intervals around the through hole and assembled on the fixing worktable.

[0012] In some embodiments, the end cap heating component includes a fixed disk fixedly connected to the motor fixing component and a heating platform located on the end face of the fixed disk facing the motor and within the through hole. The heating platform has an end cap heating position that is in contact with the end face of the motor end cap away from the motor housing cylinder and an end cap clearance position that is spaced apart from the end face of the motor end cap away from the motor housing cylinder by a preset distance. The heating platform can be driven to switch between the end cap heating position and the end cap clearance position.

[0013] In some embodiments, the end cap heating component further includes a pull-out plate that is slidably connected to the fixed plate. The pull-out plate has a first state in which it is between the fixed plate and the heating platform, and a second state in which it is outside the gap between the fixed plate and the heating platform. When the pull-out plate is in the first state, the heating platform is in the end cap heating position. When the pull-out plate is in the second state, the heating platform is in the end cap clearance position.

[0014] In some embodiments, a heating platform positioning groove is formed on the side of the pull-out plate facing the motor end cover, and a heating platform positioning block is formed on the side of the fixed plate facing the motor end cover. When the pull-out plate is in the first state, the heating platform positioning groove and the heating platform positioning block can at least form a clamping and positioning of the opposite sides of the heating platform; and / or, the pull-out plate has an anti-detachment protrusion, and a limiting flange is formed on the fixed plate that is perpendicular to the pulling direction of the pull-out plate and extends toward the side of the motor end cover. A limiting notch is formed on the limiting flange that slides with the pull-out plate, and the anti-detachment protrusion is located inside the limiting notch.

[0015] In some embodiments, the end cap pushing component further includes a top plate fixedly connected to each of the pushing assemblies, the top plate being capable of being driven to rise and fall.

[0016] In some embodiments, each of the push-up components includes a push-up column having a connecting end and a push-up end. The connecting end has a threaded section, and a fixing nut is threaded onto the threaded section. A limiting ring is provided on the side of the threaded section near the push-up end. The fixing nut and the limiting ring fix the push-up column to the top plate.

[0017] In some embodiments, an arc-shaped connecting groove is formed on the top plate, the arc of which is concentric with the central axis of the motor, and the connecting end of each of the push columns passes through and is positioned in the arc-shaped connecting groove; and / or, the end face of the fixing nut near the pressure member is a force-bearing plane, and the pressure member can press against the force-bearing plane of each fixing nut.

[0018] The present invention also provides a method for disassembling a motor end cover using the above-mentioned motor end cover disassembly device, comprising the following steps:

[0019] The operation of each barrel positioning component of the motor fixing component is controlled to insert the barrel positioning block of each barrel positioning component into each motor fixing slot of the motor to fix the motor, and the motor end cover of the motor is oriented toward the side away from the end cover pushing component.

[0020] Adjust the position of each of the push-up components so that each of the push-up components corresponds one-to-one with at least a portion of the disassembly slots, and make the push-up end of each push-up component abut against the side end face of the motor end cover near the motor housing cylinder;

[0021] The pressure-applying component is controlled to apply force along the axial direction of the motor to each of the pushing assemblies.

[0022] In some embodiments, when the motor end cover disassembly device includes an end cover heating component and the end cover heating component includes a pull-out plate, the pull-out plate is controlled to be in a first state so that the heating platform is in the end cover heating position. After each of the pushing components comes into contact with the motor end cover, the end cover heating component is controlled to heat the motor end cover. After heating for a preset time, heating is stopped and the pull-out plate is controlled to be in a second state so that the heating platform is in the end cover clearance position. Then, the pressure application component is controlled to run along the axial direction of the motor and apply force to each of the pushing components.

[0023] The present invention provides an electric motor and a motor end cover disassembly device and disassembly method for use therewith, which have the following beneficial effects:

[0024] By setting multiple spaced motor fixing slots on the outer wall of the motor housing, the motor can be fixed using a related structure. Similarly, by setting multiple spaced disassembly slots on the outer wall of the motor housing, force can be applied to the portion of the motor end cover located within each slot via the related structure. This allows force to be applied along the axial direction of the motor end cover to its outer edge, facilitating mechanized disassembly of the motor end cover and improving disassembly efficiency. Furthermore, the positional adjustment of the disassembly slots and motor fixing slots ensures balanced force application during disassembly, thereby reducing the scrap rate of the motor end cover. This is particularly beneficial for motors with plastic-encapsulated structures, significantly reducing the likelihood of breakage during disassembly. Attached Figure Description

Detailed Implementation

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] In the description of this invention, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is generally based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this invention and simplifying the description. Unless otherwise stated, these directional terms 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, and therefore should not be construed as a limitation on the scope of protection of this invention; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0038] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90° or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0039] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this invention.

[0040] See also Figures 1 to 2 As shown, according to an embodiment of the present invention, an electric motor is provided, including a motor housing cylinder 1 and a motor end cover 2 assembled at the opening of the motor housing cylinder 1. The outer wall surface of the motor housing cylinder 1 is provided with a plurality of motor fixing grooves 11 and a plurality of disassembly grooves 12, wherein each of the motor fixing grooves 11 and each of the disassembly grooves 12 are respectively arranged at intervals around the central axis of the motor housing cylinder 1. Each of the disassembly grooves 12 passes through both ends of the motor housing cylinder 1 along the axial direction of the motor housing cylinder 1 and is projected along the axial direction of the motor housing cylinder 1. The motor end cover 2 has a portion located within each of the disassembly grooves 12. It can be understood that the portion located within the disassembly groove 12 is the force-bearing surface area for pushing and disassembling the motor end cover 2 along the axial direction of the motor housing cylinder 1.

[0041] In this technical solution, by setting multiple spaced motor fixing slots 11 on the outer wall of the motor housing 1, the motor can be fixed using the relevant structure. By setting multiple spaced disassembly slots 12 on the outer wall of the motor housing 1, the relevant structure can apply force to the part of the motor end cover 2 located in each disassembly slot 12 through each disassembly slot 12. This allows force to be applied to the outer edge of the motor end cover 2 along the axial direction of the motor, thereby facilitating the mechanized disassembly of the motor end cover, improving the disassembly efficiency, and ensuring the balance of force during the disassembly process by adjusting the positions of each disassembly slot 12 and the motor fixing slot 11, thereby reducing the scrap rate of the motor end cover during disassembly. Especially for motors with plastic-encapsulated structures, this can significantly reduce the probability of motor breakage during disassembly.

[0042] In some embodiments, a plurality of motor mounting feet 13 are formed on the outer wall of the motor housing 1. Each motor mounting foot 13 is spaced apart around the central axis of the motor housing 1. Each disassembly slot 12 is located between two adjacent motor mounting feet 13. Generally, each motor mounting foot 13 is evenly spaced along the circumference of the motor. Correspondingly, each disassembly slot 12 is also evenly spaced along the circumference of the motor. This ensures the uniformity of circumferential force when the motor end cover 2 is disassembled, and further reduces the probability of motor breakage.

[0043] In some embodiments, along the axial projection of the motor housing cylinder 1, the positions of each motor fixing slot 11 and each motor mounting foot 13 correspond one-to-one and are respectively within the projection range of the motor mounting foot 13. That is, each motor fixing slot 11 and each motor mounting foot 13 maintain a one-to-one positional relationship along the axial direction of the motor. In some embodiments, each motor fixing slot 11 is located near the motor end cover 2.

[0044] In some embodiments, the motor is a plastic-encapsulated motor. In this case, the aforementioned motor housing cylinder 1 corresponds to the plastic-encapsulated motor stator housing, or in other words, the motor housing cylinder 1 is also the plastic-encapsulated motor stator. In this case, the aforementioned motor fixing slot 11, disassembly slot 12, and motor mounting feet 13 are all formed on the plastic-encapsulated motor stator.

[0045] In some embodiments, the cross-sectional shape of each of the aforementioned motor fixing slots 11 is a rectangular slot, and the cross-sectional shape of each disassembly slot 12 is a semi-circular arc slot, so as to be compatible with the cylindrical structure.

[0046] See details Figure 2As shown, in some embodiments, the motor housing cylinder 1 has a first opening 10, and a first annular platform 101 is provided on the end face of the first opening 10. The motor end cover 2 has a second annular platform 21, which is fitted onto the radial outer wall of the first annular platform 101 to achieve an interference fit between the motor end cover 2 and the motor housing cylinder 1. Thus, when the motor end cover 2 is heated, the motor end cover 2 expands due to heat, and the interference force between the motor end cover 2 and the motor housing cylinder 1 is reduced accordingly, which is conducive to the smooth disassembly of the motor end cover 2.

[0047] In some embodiments, the motor housing cylinder 1 is provided with a cable outlet clamp 14, which is located between two adjacent motor mounting feet 13, and two disassembly slots 12 are provided in the area between the two motor mounting feet 13 where the cable outlet clamp 14 is located, with the two disassembly slots 12 located on both sides of the cable outlet clamp 14.

[0048] In this technical solution, the cable outlet clamp 14 is positioned in the area between the two motor mounting feet 13, which optimizes the structural design of the motor's periphery. Simultaneously, disassembly slots 12 are provided on both sides of the cable outlet clamp 14 (around the motor circumference), ensuring balanced force application to the motor end cover 2 during disassembly while maintaining the cable outlet function of the clamp 14. In some embodiments, the aforementioned cable outlet clamp 14 is preferably miniaturized to facilitate the formation of the disassembly slots 12 within a limited space.

[0049] See also Figures 3 to 8 As shown in the embodiment of the present invention, a motor end cover disassembly device for use with the aforementioned motor is also provided, including a motor fixing component 31 and an end cover pushing component 32. The motor fixing component 31 has a plurality of barrel positioning assemblies 311. Each barrel positioning assembly 311 specifically includes a barrel positioning block 3111 and a telescopic drive member 3112. The barrel positioning block 3111 of each barrel positioning assembly 311 can be driven by the telescopic drive member 3112 to be inserted one-to-one along the radial direction of the motor. Within each of the motor fixing slots 11, the motor housing cylinder 1 is centered and clamped, thus achieving mechanical positioning of the motor. The end cover pushing component 32 includes a pushing assembly 321 and a pressure applying component 322, which are arranged one-to-one with each disassembly slot 12. The pressure applying component 322 can apply force to each of the pushing assemblies 321 along the axial direction of the motor. In specific applications, the aforementioned pressure applying component 322 is connected to the pressure output end of an external press. The aforementioned telescopic drive component 3112 can be, for example, a telescopic cylinder.

[0050] In this technical solution, the motor end cover disassembly device is equipped with a motor fixing component 31 that can fix the position of the motor and multiple pushing components 321 that can apply force to the motor end cover 2 along the axial direction of the motor. This enables the mechanized disassembly of the motor end cover 2, improves the disassembly efficiency of the motor end cover, and ensures the balance of force during the disassembly process by adjusting the position of each disassembly slot 12 and the motor fixing slot 11, thereby reducing the scrap rate of the motor end cover. Especially for motors with plastic-encapsulated structures, this significantly reduces the probability of motor breakage during the disassembly process.

[0051] In some embodiments, the motor end cover disassembly device further includes an end cover heating component 33, which heats the motor end cover 2.

[0052] In this technical solution, an end cover heating component 33 is further provided in the motor end cover disassembly device to heat the motor end cover 2 before disassembling it. This allows the motor end cover 2 to expand due to heat, thereby reducing the interference clamping force between it and the motor housing cylinder 1, making the disassembly of the motor end cover 2 smoother, and further reducing the probability of the motor breaking during disassembly.

[0053] In some embodiments, the motor fixing component 31 further includes a fixing worktable 312, on which a through hole 3121 is formed, and each of the barrel positioning components 311 is arranged at intervals around the through hole 3121 and assembled on the fixing worktable 312.

[0054] In this technical solution, each barrel positioning component 311 is assembled on a fixed workbench 312 and the through holes 3121 around it are spaced apart, which can form a centering clamping and positioning of the motor. At the same time, the aforementioned through holes 3121 serve as a release channel for the end cap, resulting in a simple and compact structure.

[0055] In some embodiments, the end cap heating component 33 includes a fixing plate 331 fixedly connected to the motor fixing component 31 and an end face of the fixing plate 331 facing the motor (i.e., Figure 4 A heating platform 332 is located on the top side end face (shown in the orientation) and inside the through hole 3121. The heating platform 332 has an end cover heating position that is in contact with the side end face of the motor end cover 2 away from the motor housing cylinder 1, and an end cover clearance position that is spaced apart from the side end face of the motor end cover 2 away from the motor housing cylinder 1 by a preset distance. The heating platform 332 can be driven to switch between the end cover heating position and the end cover clearance position.

[0056] In this technical solution, the heating platform 332 in the end cover heating component 33 can switch between the end cover heating position and the end cover yielding position. Thus, when the motor end cover 2 needs to be heated, the heating platform 332 can be in the end cover heating position. After heating is completed, the heating platform 332 is switched to the end cover yielding position, which facilitates the disassembly and detachment of the motor end cover 2.

[0057] In some embodiments, the end cap heating component 33 further includes a pull-out plate 333, which is slidably connected to the fixed plate 331. The pull-out plate 333 has a first state between the fixed plate 331 and the heating platform 332, and a second state outside the gap between the fixed plate 331 and the heating platform 332. When the pull-out plate 333 is in the first state, the heating platform 332 is in the end cap heating position. When the pull-out plate 333 is in the second state, the heating platform 332 is in the end cap clearance position. It is understood that in practical applications, the operator switches between the first and second states by applying force to the pull-out plate 333 at the force application position. The thickness of the pull-out plate 333 is greater than the overall thickness of the motor end cap 2.

[0058] In this technical solution, a pull plate 333 is provided inside the end cap heating component 33. By pulling the pull plate 333, the first state and the second state can be switched, thereby enabling the heating platform 332 to switch between the end cap heating position and the end cap yielding position in a lifting manner. The structure is simple and the operation is convenient.

[0059] To facilitate the smooth insertion of the pull-out plate 333 into the gap between the bottom surface of the heating platform 332 and the top surface of the fixed plate 331, thereby enabling the raising and lowering of the heating platform 332, the pull-out plate 333 has a wedge-shaped surface near the head of the heating platform 332, and the thickness of the wedge-shaped surface gradually decreases towards the heating platform 332. In other embodiments, the outer circumference of the bottom end of the heating platform 332 is chamfered or rounded, which also allows the pull-out plate 333 to smoothly enter under the bottom surface of the heating platform 332.

[0060] In some embodiments, the pull-out plate 333 faces the side of the motor end cover 2 (i.e.) Figure 4A heating platform positioning groove 3331 is formed on the top side of the plate (shown in the diagram). A heating platform positioning block 3311 is formed on the side of the fixed plate 331 facing the motor end cover 2. When the pull plate 333 is in the first state, the heating platform positioning groove 3331 and the heating platform positioning block 3311 can at least form a clamping and positioning of the opposite sides of the heating platform 332. When the pull plate 333 is in the first state, while the pull plate 333 pushes the heating platform 332 up to make close contact with the bottom end face of the motor end cover 2, the aforementioned heating platform positioning groove 3331 and the heating platform positioning block 3311 together form a clamping and positioning of the heating platform 332, ensuring that the heating platform 332 can reliably and effectively heat the motor end cover 2.

[0061] In some embodiments, the aforementioned heating stage 332 is a cylindrical metal body (such as aluminum or copper) with a built-in heating resistance wire. In this case, the position where the aforementioned heating stage positioning groove 3331 and heating stage positioning block 3311 contact the circumferential side wall of the heating stage 332 is an arc surface, so as to achieve the centering and positioning of the heating stage 332.

[0062] In some embodiments, a support leg 3122 is provided on each of the four sides of the bottom side of the fixed workbench 312. In this case, the aforementioned end cap heating component 33 is assembled on the bottom side of the fixed workbench 312 and is fixedly connected to each of the support legs 3122 through its fixing plate 331.

[0063] In some implementations, see reference Figure 6 and Figure 7 As shown, the pull-out plate 333 has an anti-detachment boss 3332, and the fixed plate 331 has a limiting flange 3312 that is perpendicular to the pulling direction of the pull-out plate 333 and extends toward the side of the motor end cover 2. The limiting flange 3312 has a limiting notch 3313 that slides with the pull-out plate 333. The anti-detachment boss 3332 is located inside the limiting notch 3313 (that is, the side of the limiting flange 3312 that is close to the heating table positioning block 3311) to prevent the pull-out plate 333 from detaching from the fixed plate 331.

[0064] In this technical solution, a limiting flange 3312 is provided on the pull-out plate 333 to form an inner and outer obstruction with the limiting notch 3313 on the fixed plate 331. This can prevent the pull-out plate 333 from being pulled out of the fixed plate 331 when switching from the first state to the second state, thus ensuring the compactness of the structure.

[0065] In some embodiments, the end cap pushing component 32 further includes a top plate 323 fixedly connected to each of the pushing assemblies 321. The top plate 323 can be driven to rise and fall. Specifically, a corresponding lifting device (such as a sliding motor module or cylinder) is separately configured for the top plate 323 so that it can be controlled to rise when the motor is placed in a fixed position, which facilitates the motor placement and positioning process. See details. Figure 4 As shown, a top plate lifting column 3232 is installed at each of the four corners of the top surface of the top plate 323.

[0066] In this technical solution, the top plate 323 fixes each pushing component 321 into a whole, which can further improve the structural compactness of the device, and at the same time facilitates the synchronous and balanced force application of each pushing component 321 to the motor end cover 2.

[0067] In some embodiments, each of the push-up components 321 includes a push-up column 3211. In some embodiments, the cross-section of the push-up column 3211 is circular, which matches the semi-circular arc of the disassembly slot 12, thereby increasing the stability of the push-up column 3211 when pushing the motor end cover 2. The push-up column 3211 has a connecting end (not indicated in the figure, i.e.) Figure 4 The top of the middle) and the pushing end (not labeled in the figure, i.e. Figure 4 The bottom end of the connecting end has a threaded section (not shown in the figure), and a fixing nut 3212 is threaded onto the threaded section. A limiting ring 3213 is provided on the side of the threaded section near the pushing end. The fixing nut 3212 and the limiting ring 3213 fix the pushing column 3211 to the top plate 323.

[0068] In this technical solution, the clamping force between the limiting ring 3213 and the fixing nut 3212 is used to achieve a detachable and fixed connection with the top plate 323, which is simple and reliable.

[0069] In some implementation methods, see details. Figure 5 As shown, an arc-shaped connecting groove 3231 is formed on the top plate 323, which runs through both sides of the top plate 323. The arc shape of the arc-shaped connecting groove 3231 is concentric with the central axis of the motor. The connecting ends of each push column 3211 pass through and are positioned in the arc-shaped connecting groove 3231.

[0070] In this technical solution, by setting an arc-shaped connecting groove 3231 that runs through both sides of the top plate 323, and the arc is concentric with the central axis of the motor, the position of the pushing component 321 can be adjusted along the circumference of the motor according to the actual situation, thereby improving the adaptability of the device to different motors.

[0071] The end face of the fixing nut 3212 near the pressure applying member 322 is a force-bearing plane. The pressure applying member 322 can press against the force-bearing plane of each fixing nut 3212, thus directly applying the force applied by the pressure applying member 322 to the force-bearing plane of each fixing nut 3212, ensuring efficient force transmission. Specifically, the aforementioned pressure applying member 322 includes a plate with a force-bearing surface (not labeled in the figure) and a connecting cylinder (not labeled in the figure) fixed to one end face of the plate. The connecting cylinder is detachably connected to the pressure output end of the press.

[0072] According to an embodiment of the present invention, a method for disassembling a motor end cover using the above-described motor end cover disassembly device is also provided, comprising the following steps:

[0073] The operation of each barrel positioning component 311 of the motor fixing component 31 is controlled to insert the barrel positioning block 3111 of each barrel positioning component 311 into each motor fixing slot 11 of the motor to fix the motor, and the motor end cover 2 of the motor is placed towards the side away from the end cover pushing component 32, that is, the motor end cover 2 is placed downward.

[0074] Adjust the position of each of the push-pull components 321 so that each of the push-pull components 321 corresponds one-to-one with at least a portion of the disassembly slots 12, and make the pushing end of each push-pull component 321 (i.e., Figure 4 The bottom end (as shown) abuts against the side end face of the motor end cover 2 near the motor housing cylinder 1;

[0075] The pressure-applying component 322 is controlled to apply force along the axial direction of the motor to each of the pushing components 321. Thus, under the balanced downward pressure of each pushing component 321, the motor end cover 2 smoothly detaches from the motor housing cylinder 1, realizing the mechanized disassembly of the motor end cover, improving the disassembly efficiency of the motor end cover, and the balance of force applied during the disassembly process can be ensured by adjusting the position of each disassembly slot 12 and the motor fixing slot 11, thereby reducing the scrap rate of the motor end cover during disassembly.

[0076] In some embodiments, when the motor end cover disassembly device includes an end cover heating component 33 and the end cover heating component 33 includes a pull plate 333, the pull plate 333 is controlled to be in a first state so that the heating platform 332 is in the end cover heating position. After each of the pushing components 321 comes into contact with the motor end cover 2, the end cover heating component 33 is controlled to heat the motor end cover 2. After heating (to 150°C in one specific embodiment) for a preset time (5 minutes in one specific embodiment), the heating is stopped and the pull plate 333 is controlled to be in a second state so that the heating platform 332 is in the end cover clearance position. That is, after the heating platform 332 descends a certain distance, the pressure component 322 is controlled to run along the axial direction of the motor and apply force to each of the pushing components 321. Since the motor end cover 2 is heated first before being pushed apart, the probability of the motor breaking during the disassembly process can be further reduced.

[0077] It will be readily understood by those skilled in the art that, without conflict, the advantageous technical features of the above-mentioned methods can be freely combined and superimposed.

The above description is only a preferred embodiment of the present invention.
