Description

Technical Field

[0001] This application relates to the field of motor recycling technology, and in particular to a disassembly device for separating the motor housing from the stator. Background Technology

[0002] The motor is mainly composed of three parts: the housing, the stator, and the rotor. The stator is inserted into the housing by interference fit, and the rotor is inserted into the center hole of the stator by transition fit. The stator and rotor are magnetically attracted together.

[0003] In the field of motor recycling, the disassembly of the motor casing and stator is a critical but technically complex process.

[0004] Currently, most mainstream motor housing and stator disassembly equipment on the market employs mechanical ejection technology, such as using a cylinder or screw-driven top plate to apply axial thrust to the housing for separation. While this type of equipment offers improvements in automation and disassembly efficiency, it also has significant drawbacks:

[0005] The aforementioned mechanical ejection technology directly applies axial force to the interference fit housing, resulting in high stress concentration at the mating surface between the housing and the stator. This easily leads to plastic deformation of the housing or stator, resulting in a low direct recycling rate of the motor housing or stator. Utility Model Content

[0024] When an upward force is applied to the slide, the gripping tool switches from the expanded state to the retracted state;

[0025] When the slide is released, the gripping tool switches from the retracted state to the expanded state under the action of gravity; or, when downward pressure is applied to the slide, the gripping tool switches from the retracted state to the expanded state.

[0026] In one embodiment, each of the claw bodies is provided with a first elastic contact member, which is used to abut against the wall of the center hole of the stator.

[0030] The gripping device is movably mounted on the machine body between the disassembly station and the conveying mechanism, so that the gripping device can transfer the stator to the conveying mechanism.

[0031] In one embodiment, the heating device includes:

[0032] A third drive mechanism, mounted on the machine body, wherein the output end of the third drive mechanism is vertically movable; and

[0033] A heater is connected to the output end of the third drive mechanism. The heater is equipped with a heating element that can be mounted outside or away from the outer stator assembly as the output end of the third drive mechanism moves.

[0034] In one embodiment, the heating device further includes:

[0035] A first protective cover, disposed on the machine body, has a first inner cavity and an inlet / outlet, the inlet / outlet communicating with the first inner cavity, the inlet / outlet allowing the output end of the first drive mechanism, the positioning component, and the outer stator assembly located on the positioning component to enter and exit the first inner cavity, the heating component being located within the first inner cavity; and

[0036] The second protective cover is disposed on the output end of the third drive mechanism. The second protective cover has a second inner cavity, and the heater, except for the heating component, is located inside the second inner cavity.

[0038] A second cooling device is disposed on the body and is used to cool the first protective cover and / or the second protective cover.

[0047] The advantages or beneficial effects of the above technical solutions include at least the following:

[0048] This invention relates to a disassembly device, which includes a heating station and a disassembly station on the machine body. The heating device heats the outer shell and stator assembly, causing the outer shell to expand in a controlled manner until it forms a transitional fit with the stator. Since the thermal expansion coefficient of the outer shell is greater than that of the stator, the stator maintains its original structure during the expansion of the outer shell. This increases the fit clearance between the outer shell and stator before disassembly, significantly reducing separation resistance and thus reducing the separation gripping force, thereby avoiding structural damage caused by mechanical forced disassembly. Simultaneously, a first drive mechanism moves a positioning component to transport the heated outer shell and stator assembly to the disassembly station, at which point the outer shell is still... While maintaining expansion margin, the high strength of the outer shell material ensures structural stability during disassembly. Then, the locking component precisely constrains the displacement of the outer shell at the disassembly station, while the gripping device axially grips the stator. The gripping force only needs to overcome the remaining transition friction, thus transforming the traditional rigid confrontation into flexible decoupling. Therefore, by utilizing the synergistic effect of thermal expansion margin and mechanical gripping, the outer shell and stator can be separated without damage, maintaining the structural integrity of the outer shell or stator, or reducing secondary damage to the outer shell and stator during the separation process. This can effectively improve the direct recycling rate of the outer shell or stator, reduce the secondary processing rate, and thus reduce costs.

[0060] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0061] See Figures 1-7 This invention illustrates a preferred embodiment of a disassembly device for separating a motor housing from its stator, comprising:

[0062] Machine body 1, which has a heating station and a disassembly station;

[0063] Heating device 2 is installed on the machine body 1. Heating device 2 is used to heat the outer shell stator assembly 30 located at the heating station so that the outer shell 301 expands to transition fit with the stator 302, that is, the outer shell 301 expands from an interference fit with the stator 302 to a transition fit with the stator 302.

[0064] The first drive mechanism 3 is mounted on the machine body 1, and the output end of the first drive mechanism 3 can move between the heating station and the disassembly station.

[0065] Positioning component 4 is connected to the output end of the first drive mechanism 3. Positioning component 4 can move with the output end of the first drive mechanism 3. Positioning component 4 is used to support the outer shell stator assembly 30.

[0066] Locking component 5 is disposed on the machine body 1 and located on the side near the disassembly station. Locking component 5 has a locked state and an unlocked state. In the locked state, locking component 5 abuts against the outer casing 301 in the outer casing stator assembly 30 to restrict the movement of the outer casing 301, that is, to restrain the outer casing 301 on the positioning component 4 and prevent displacement of the outer casing 301. In the unlocked state, locking component 5 separates from the outer casing 301 to release the outer casing 301, allowing the outer casing 301 to be removed from the positioning component 4.

[0067] The gripping device 6 is mounted on the machine body 1. The gripping device 6 is used to axially grip the stator 302 located at the disassembly station to separate the stator 302 from the outer casing 301.

[0068] The disassembly device of this invention has a heating station and a disassembly station on the machine body 1. The heating device 2 heats the outer shell stator assembly 30, causing the outer shell 301 to expand in a controlled manner until it forms a transitional fit with the stator 302. Since the thermal expansion coefficient of the outer shell 301 is greater than that of the stator 302, the stator 302 maintains its original structure while the outer shell 301 expands. Therefore, it can increase the fit clearance between the outer shell 301 and the stator 302 before disassembly, significantly reducing separation resistance, i.e., reducing the separation gripping force, thereby avoiding structural damage caused by mechanical forced disassembly. Simultaneously, a first drive mechanism 3 drives a positioning component 4 to move the heated outer shell stator assembly 30 to the disassembly station. At this time, the outer shell 301 still… While maintaining expansion margin, the outer shell 301 material has high strength to ensure structural stability during disassembly. Then, the locking component 5 precisely constrains the displacement of the outer shell 301 at the disassembly station, while the gripping device 6 performs axial gripping on the stator 302. The gripping force only needs to overcome the remaining transition friction, realizing the transformation of traditional rigid confrontation into flexible decoupling. Therefore, by utilizing the synergistic effect of thermal expansion margin and mechanical gripping, the outer shell 301 and stator 302 can be separated without damage, so that the outer shell 301 or stator 302 maintains structural integrity or reduces secondary damage to the outer shell 301 and stator 302 during the separation process. This can effectively improve the direct recycling rate of the outer shell 301 or stator 302, reduce the secondary processing rate, and thus reduce costs.

[0069] It is understood that the gripping action can be triggered when the temperature of the outer shell 301 drops to a level that allows it to maintain structural stability. At this time, the outer shell 301 still maintains its expansion margin, but the material strength recovers to more than 80% of that at room temperature, ensuring structural stability during disassembly.

[0070] Understandably, during heating, the heating temperature is precisely controlled below the recrystallization temperature of the outer shell 301 to ensure that the outer shell 301 expands fully and to avoid phase transformation or strength degradation of the outer shell 301 material. In addition, after separating the outer shell 301 from the stator 302, the outer shell 301 is allowed to cool statically at room temperature to avoid forced cooling of the outer shell 301, thereby preventing the strength of the outer shell 301 from deteriorating.

[0071] In one embodiment, the first drive mechanism 3 is a cylinder. The cylinder, as a drive source, features a simple structure and rapid response, enabling quick lateral movement of the positioning component 4 to meet the high efficiency requirements of automated production lines. Furthermore, this design fully leverages the high standardization of pneumatic components, facilitating maintenance and replacement while maintaining controllable costs. The compact structure of the cylinder also helps optimize the overall equipment layout and reduces space occupation. In addition, the inherent overload protection function of the pneumatic system can automatically depressurize under abnormal conditions, providing passive safety protection for the gripping device 6.

[0072] Of course, in other embodiments, the first drive mechanism 3 can also be any of the following linear drive mechanisms: hydraulic cylinder, linear motor, motor and linear drive module (such as lead screw and nut pair, gear and rack mechanism).

[0073] See Figure 4 In one embodiment, the disassembly device for separating the motor housing from the stator further includes:

[0074] The second guide component 40 includes:

[0075] The second guide component 401 is disposed on the body 1; and

[0076] The second sliding component 402 is slidably mounted on the second guide component 401 and connected to the first support platform, which supports the positioning component 4. The cooperation between the second guide component 401 and the second sliding component 402 provides high-precision linear motion guidance for the first support platform, ensuring a stable and reliable movement trajectory for the positioning component 4 and preventing deviation or wobbling. Furthermore, this first guide structure effectively distributes the radial load of the first drive mechanism 3, extending the service life of the transmission system and reducing the frictional resistance of the moving components, making the drive smoother and more efficient.

[0077] See Figure 2In one embodiment, the gripping device 6 includes:

[0078] A second drive mechanism 61 is mounted on the body 1, and its output end is vertically movable; and

[0079] The gripping tool 62 is connected to the output end of the second drive mechanism 61. The gripping tool 62 has a retracted state and an expanded state. In the retracted state, the gripper body 622 of the gripping tool 62 retracts towards the vertical center line of the gripping tool 62 so that the gripping tool 62 can enter and exit the center hole of the stator 302. In the expanded state, the gripper body 622 of the gripping tool 62 expands circumferentially so that the gripper body 622 of the gripping tool 62 can abut against the wall of the center hole of the stator 302 and be connected to the stator 302. The gripper body 622 is movable and can switch between the retracted state and the expanded state. Thus, through the coordinated operation of the second drive mechanism 61 and the gripping tool 62, the stator 302 can be gripped without damage. The second drive mechanism 61 controls the precise vertical movement of the gripping tool 62, ensuring accurate positioning of the gripping tool 62 along the axial direction of the stator 302. The gripping tool 62 employs a radially variable claw body 622 structure. Through a mechanical conversion mechanism between contracted and expanded states, it solves the problem of indentation defects caused by traditional end-face clamping and overcomes the common interference problem when gripping the center hole. In the contracted state, the claw body 622 converges towards the vertical centerline to form a compact profile smaller than the diameter of the center hole of the stator 302, ensuring smooth insertion of the gripping tool 62 into the center hole of the stator 302. In the expanded state, the claw body 622 circumferentially... The expansion mechanism forms full contact with the central hole wall of the stator 302, utilizing the circumferential force distribution characteristics to disperse stress and prevent local stress concentration from causing deformation of the central hole of the stator 302. This ensures gripping stability while avoiding local plastic deformation of the central hole wall of the stator 302, enabling non-destructive gripping of the stator 302. The gripping device 6 integrates axial movement and radial deformation functions into a single drive system, simplifying the actuator while achieving precise control of the stator 302 gripping process. In particular, by replacing the traditional rigid clamping with a mechanically adaptive expansion contact method, it effectively protects the precision-machined surface of the stator 302 while ensuring gripping reliability. It is especially suitable for automated handling scenarios of motor stator 302 with strict surface quality requirements.

[0080] See Figure 7 In one embodiment, the gripping tool 62 includes:

[0081] Connecting component 621 is connected to the output end of the second drive mechanism 61;

[0082] At least two claw bodies 622 are arranged at intervals around the vertical center line of the connecting member 621;

[0083] The slide 623 is vertically movable and sleeved on the connecting member 621;

[0084] At least two first links 624, the first end of the first link 624 is pivotally connected to the slide 623, and the second end of the first link 624 is connected to the corresponding claw body 622;

[0085] The fixing seat 625 is disposed on the connecting member 621 and is located below the slide 623; and

[0086] At least two second links 626, the first end of the second link 626 is pivotally connected to the fixed seat 625, and the second end of the second link 626 is connected to the corresponding claw body 622;

[0087] When an upward force is applied to the slide 623, the gripping tool 62 switches from the expanded state to the retracted state;

[0088] When the slide 623 is released, the gripping tool 62 switches from a retracted state to an expanded state under the influence of gravity; or, when downward pressure is applied to the slide 623, the gripping tool 62 switches from a retracted state to an expanded state. Thus, the coordinated operation of the connecting component 621, the slide 623, the fixed base 625, and the linkage mechanism composed of the first link 624 and the second link 626 enables the claw body 622 to switch between the retracted and expanded states. The connecting component 621, as the core load-bearing structure, ensures stable docking with the second drive mechanism 61. The vertical arrangement of the slide 623 and the fixed base 625, along with the first link 624 and the second link 626, forms a double-pivot linkage mechanism, allowing the claw body 622 to precisely switch between radial retraction and expansion. Furthermore, the gripping tool 62 achieves state switching using gravity or simple force; when the slide 623 is released or subjected to downward pressure... The claw body 622 expands outward through the linkage of the first link 624 and the second link 626 until it contacts the central hole wall of the stator 302. At this time, the reaction force on the claw body 622 is transmitted to the slide block 623 along the first link 624, forming a downward component force. This component force, together with the weight of the slide block 623 itself or the external downward pressure, keeps the slide block 623 in a stable downward state, thereby maintaining the expansion posture of the claw body 622. At the same time, because the pivot point layout of the first link 624 and the second link 626 forms a structure that passes through the center or is close to the dead point, the claw body 622 needs to overcome a certain lever arm after expanding to the position before it can move in the opposite direction. Thus, without external active force, it can maintain the expansion posture of the claw body 622. When the slide 623 is lifted, the claw 622 remains in an expanded state due to the mechanical self-locking effect, ensuring gripping stability. Furthermore, the radial constraint of the central hole wall of the stator 302 on the claw 622 further restricts the possibility of retraction of the linkage mechanism, forming a two-way mechanical balance. Only when a specific lifting force is applied to break this balance will the claw 622 disengage from the self-locking state and retract. This design cleverly utilizes the mechanical characteristics of the mechanism to achieve reliable gripping, preventing accidental release without the need for an additional locking device. When the slide 623 is lifted, the linkage mechanism drives the claw 622 to retract synchronously, reducing driving complexity and improving operational reliability. Additionally, each claw 622 surrounds... The vertical centerline is evenly distributed and synchronously controlled by multiple links to ensure uniform contact with the central hole wall of the stator 302 during expansion, avoiding stress concentration on one side. In addition, the vertical sliding design of the slide 623 along the connecting component 621 makes the force transmission path clear and controllable, forming a stable kinematic pair structure in conjunction with the reference positioning function of the fixed seat 625. The gripping tool 62 integrates the gripping force and the reset force into the same mechanical system, which can achieve bidirectional state switching without additional elastic elements. It simplifies the structure and improves durability, making it particularly suitable for high-frequency automated operation scenarios. Its combination of active expansion and passive contraction mode ensures gripping reliability and optimizes energy consumption efficiency.

[0089] See Figure 7In one embodiment, each claw body 622 is provided with a first elastic contact component 627, which is used to abut against the wall of the center hole of the stator 302. Firstly, the introduction of the first elastic contact component 627 allows the claw body 622 to adapt to different dimensional tolerance changes through elastic deformation during the expansion position, ensuring a tight fit with the wall of the center hole of the stator 302, thus improving gripping stability and avoiding surface damage caused by rigid contact. Secondly, the buffering properties of the elastic material of the first elastic contact component 627 effectively absorb vibrations and impacts during the gripping process, preventing micro-deformation or scratches on the stator 302 due to rigid collisions during handling. Thirdly, by compensating for manufacturing errors and assembly gaps through the deformation of the first elastic contact component 627, the machining accuracy requirements of the center hole of the stator 302 can be reduced, improving the compatibility and applicability of the gripping tool 62. In addition, the first elastic contact component 627 increases the actual contact area between the claw body 622 and the central hole wall of the stator 302. By uniformly distributing the load through elastic pressure, it further reduces the risk of local stress concentration and ensures that the central hole wall of the stator 302 is not damaged by pressure. Furthermore, the controllable friction coefficient of the first elastic contact component 627 not only ensures sufficient static friction to prevent slippage during gripping, but also reduces adhesion during release, making the process of picking up and placing the stator 302 smoother and more reliable. This structure innovatively combines rigid positioning with flexible contact, achieving non-destructive gripping operation of the stator 302 while maintaining mechanical precision, which is conducive to further improving the direct recycling rate of the stator 302.

[0090] In one embodiment, the first elastic contact component 627 may be a structure made of an elastic material, such as any one of rubber, polyurethane, etc.

[0091] Of course, in other embodiments, the first elastic contact member 627 may also be a floating contact head supported by a spring, for example, a radially retractable contact head is provided in the claw body 622, with a compression spring or disc spring configured inside to provide adaptive clamping force.

[0092] Of course, in other embodiments, the first elastic contact component 627 can also be an airbag-type contact structure, for example, an inflatable airbag is integrated on the surface of the claw body 622, and the contact pressure is adjusted by air pressure, which is suitable for fragile workpieces.

[0093] In one embodiment, the connecting component 621 is detachably connected to the output end of the second drive mechanism 61. This detachable connection allows the gripping tool 62 to be quickly separated from or assembled from the second drive mechanism 61, facilitating the replacement of gripping tools 62 with suitable ones for different stator 302 specifications, significantly improving the equipment's versatility and production line flexibility. Secondly, this design achieves mechanical and functional decoupling through modular interfaces (such as flanges, quick-change clips, or threaded connections), ensuring reliable power transmission and simplifying maintenance procedures. When the gripping tool 62 wears out or requires process adjustments, it can be replaced independently, reducing downtime and maintenance costs. Thirdly, the detachable structure optimizes the flexibility of equipment layout, allowing for rapid adjustment of the spatial relative positions of the second drive mechanism 61 and the gripping tool 62 according to production needs, adapting to diverse production line configurations. Simultaneously, the standardized interface design facilitates the serialization of the gripping tool 62, forming a library of gripping tools 62 covering different stator 302 models.

[0094] See Figure 7 In one embodiment, the slide 623 is provided with a pull ring 628 for hand operation to facilitate lifting the slide 623.

[0095] In one embodiment, the second drive mechanism 61 can specifically be a cylinder. The cylinder, as a drive source, features a simple structure and rapid response, enabling quick lifting and lowering of the gripping tool 62 to meet the high efficiency requirements of automated production lines. Secondly, utilizing the smooth characteristics of pneumatic transmission, it can effectively buffer the impact force when the gripping tool 62 contacts the stator 302, avoiding damage to precision parts caused by rigid collisions. Thirdly, the adjustable thrust of the cylinder allows it to adaptively adjust the output force according to the weight of stators 302 of different specifications, ensuring sufficient clamping force during gripping without causing deformation of the stator 302 due to overload. Furthermore, this design fully leverages the high standardization of pneumatic components, facilitating maintenance and replacement while keeping costs under control. The compact structure of the cylinder also helps optimize the overall equipment layout and reduces space occupation. In addition, the inherent overload protection function of the pneumatic system can automatically release pressure in abnormal situations, providing passive safety protection for the gripping device 6.

[0096] Of course, in other embodiments, the second drive mechanism 61 can also be any of the following linear drive mechanisms: hydraulic cylinder, linear motor, motor and linear drive module (such as lead screw and nut pair, gear and rack mechanism).

[0097] Of course, in other embodiments, the gripping tool 62 can also be an adsorption mechanism. The adsorption mechanism uses the negative pressure generated by the suction cup to adsorb the stator 302, thereby realizing the gripping and transportation of the stator 302.

[0098] Of course, in other embodiments, the gripping tool 62 can be any one of a magnetic adsorption mechanism, a vacuum adsorption mechanism, etc.

[0099] See Figure 1 In one embodiment, the disassembly device for separating the motor housing from the stator further includes:

[0100] The first cooling device 7 is used to cool the stator 302.

[0101] Conveying mechanism 8 is provided on the machine body 1. Conveying mechanism 8 is used to drive stator 302 to move through the first cooling device 7.

[0102] The gripping device 6 is movably mounted on the machine body 1 between the disassembly station and the conveying mechanism 8, enabling the gripping device 6 to transfer the stator 302 to the conveying mechanism 8. Thus, after separating the outer casing 301 from the stator 302, the gripping device 6 is driven to move from the disassembly station above the conveying mechanism 8, and then the gripping device 6 is driven to place the stator 302 onto the conveying mechanism 8. The conveying mechanism 8 then transports the stator 302. Simultaneously, during the transport of the stator 302, the conveying mechanism 8 carries the stator 302 through the cooling chamber of the first cooling device 7, where the first cooling device 7 cools the stator 302. This cooling process accelerates the recovery of the material properties of the stator 302, eliminates the risk of thermal deformation, and improves the direct recycling rate or remanufacturing qualification rate of the stator 302.

[0103] See Figure 2 and Figure 6 In one embodiment, the disassembly device for separating the motor housing from the stator further includes a first guide assembly 9, the first guide assembly 9 comprising:

[0104] A first guide component 91 is disposed on the machine body 1 and is located between the disassembly station and the conveying mechanism 8; and

[0105] The first sliding component 92 is slidably disposed on the first guide component 91, and the gripping device 6 is disposed on the first sliding component 92, so that the gripping device 6 can move between the disassembly station and the conveying mechanism 8. Thus, after the housing 301 is separated from the stator 302, the gripping device 6 can be moved from the disassembly station to the conveying mechanism 8 by manually pushing the first sliding component 92. The combined arrangement of the first guide component 91 and the first sliding component 92 can guide the movement of the gripping device 6, ensuring that the movement of the gripping device 6 is stable and smooth.

[0106] Of course, in other embodiments, the gripping device 6 can also be driven to move between the disassembly station and the conveying mechanism 8 automatically. In this case, the disassembly equipment also includes a fourth drive mechanism, which is located on the body 1. The output end of the fourth drive mechanism is connected to the first sliding member 92. The fourth drive mechanism is used to drive the first sliding member 92 to move between the disassembly station and the conveying mechanism 8 to transfer the stator 302 to the conveying mechanism 8. Thus, after separating the outer casing 301 from the stator 302, the fourth drive mechanism drives the gripping device 6 to move from the disassembly station to above the conveying mechanism 8. The gripping device 6 then places the stator 302 on the conveying mechanism 8, which then transports the stator 302 out. During the transport of the stator 302, the conveying mechanism 8 carries the stator 302 through the cooling chamber of the first cooling device 7, which cools the stator 302. This cooling process accelerates the recovery of the material properties and eliminates the risk of thermal deformation, improving the direct recycling rate or remanufacturing qualification rate of the stator 302. The coordinated operation of the conveying mechanism 8 and the fourth drive mechanism enables the automated transfer of the disassembled stator 302, avoiding secondary damage caused by manual handling.

[0107] In one embodiment, the fourth drive mechanism includes:

[0108] The motor is mounted on the machine body 1;

[0109] A lead screw, rotatably mounted on the machine body 1, is connected to the output shaft of the motor and can rotate with the output shaft of the motor; and

[0110] A nut, fitted onto a lead screw, moves with the rotation of the lead screw and is connected to the first sliding component 92, thereby driving the gripping device 6 to move between the disassembly station and the conveying mechanism 8. The structure where the motor drives the lead screw to rotate and the nut to move linearly achieves precise control over the position switching of the gripping device 6 between the disassembly station and the conveying mechanism 8. The high-precision characteristics of the lead screw drive ensure that the gripping device 6 can accurately align with the center hole of the stator 302, improving the positioning accuracy of disassembly. Secondly, this fourth drive mechanism simplifies the transmission chain structure by converting rotational motion into linear motion, reducing the accumulation of errors caused by intermediate conversion links. Simultaneously, the self-locking characteristic of the lead screw and nut pair maintains the stable position of the gripping device 6 in the event of a power outage, preventing accidental movement and workpiece damage. The direct connection between the motor and the lead screw improves energy transfer efficiency, and the moving speed of the gripping device 6 can be flexibly adjusted by controlling the motor speed to adapt to different production cycle requirements. Furthermore, the direct connection between the nut and the first sliding component 92 forms a compact force transmission path, making the overall structural layout more rational and reducing space occupation.

[0111] Of course, in other embodiments, the fourth drive mechanism can also be a commonly used linear drive mechanism such as a cylinder, hydraulic cylinder, or linear motor.

[0112] To facilitate the installation of the gripping device 6, in one embodiment, a second support platform is provided on the first sliding component 92, and the second support platform supports the second drive mechanism 61 of the gripping device 6.

[0113] In one embodiment, the conveying mechanism 8 can be any one of the following structures: chain plate conveying mechanism 8 (composed of multiple metal chain plates hinged into a closed loop structure), roller conveying mechanism 8 (composed of multiple parallel drive rollers forming a conveying surface, with each drive roller linked by a chain or synchronous belt and driven to rotate by a geared motor).

[0114] In one embodiment, the first cooling device 7 can be a wind-cooled cooling device, which can include: a vortex tube or a compressed air system for generating cooling airflow; and a high-pressure nozzle, one end of which is connected to the vortex tube or compressed air system and the other end of which is connected to the cooling chamber. The high-pressure nozzle is used to spray the cooling airflow onto the stator 302 passing through the cooling chamber, thereby achieving rapid cooling of the stator 302.

[0115] Of course, in other embodiments, the first cooling device 7 may be any one of a liquid cooling device, a contact thermal conduction cooling device, a phase change cooling device, etc.

[0116] See Figures 3-4 In one embodiment, the heating device 2 includes:

[0117] The third drive mechanism 21 is mounted on the body 1, and its output end is vertically movable; and

[0118] Heater 22 is connected to the output end of the third drive mechanism 21. Heater 22 is equipped with a heating component, which can be fitted onto or away from the outer stator assembly 30 as the output end of the third drive mechanism 21 moves. In this way, by setting the third drive mechanism 21 in the heating device 2 to drive the heater 22 to move vertically, the heating component can be accurately fitted onto or completely removed from the outer stator assembly 30, realizing the rapid alignment and removal of the heating component and avoiding interference with the movement of the outer stator assembly 30 with the first drive mechanism 3. In addition, when the heating component is heating along with the outer shell 301, the heating component fitted onto the outer shell 301 can achieve uniform heating of the outer shell 301 and avoid uneven heating of the outer shell 301.

[0119] In one embodiment, the heater 22 is specifically a high-frequency heater. Thus, the high-frequency induction heating principle is used to achieve rapid and uniform heating of the outer casing 301, significantly improving thermal expansion efficiency; secondly, electromagnetic induction directly acts on the metal outer casing 301, avoiding energy loss caused by traditional contact heating; and thirdly, the high-frequency heater has precise temperature control capabilities, dynamically adjusting the heating power to adapt to outer casings 301 of different materials and thicknesses.

[0120] See Figures 3-4 In one embodiment, the heating device 2 further includes:

[0121] A first protective cover 23 is mounted on the body 1. The first protective cover 23 has a first inner cavity and an inlet / outlet. The inlet / outlet communicates with the first inner cavity. The inlet / outlet allows the output end of the first drive mechanism 3, the positioning component 4, and the outer stator assembly 30 located on the positioning component 4 to enter and exit the first inner cavity. The heating component is located inside the first inner cavity.

[0122] The second protective cover 24 is located on the output end of the third drive mechanism 21. The second protective cover 24 has a second inner cavity, and the heater 22, except for the heating component, is located in the second inner cavity.

[0123] The disassembly equipment used to separate the motor housing from the stator also includes:

[0124] The second cooling device 10, mounted on the machine body 1, is used to cool the first protective cover 23 and / or the second protective cover 24. Thus, the first protective cover 23 isolates the heating element from the external environment, preventing heat loss and improving thermal efficiency, while also avoiding the risk of burns to operators. The inlet and outlet design of the first protective cover 23 ensures smooth entry and exit of the outer shell stator assembly 30 while maintaining the airtightness of the heating cavity. Secondly, the second protective cover 24 encloses and protects the non-working parts of the heater 22 (excluding the heating element), reducing the impact of high temperatures on these parts. Furthermore, the second cooling device 10 effectively controls the temperature of the first protective cover 23 or the second protective cover 24, ensuring stable operation of the equipment over a long period and reducing the probability of burns to operators, thus improving safety.

[0125] In one embodiment, the third drive mechanism 21 is specifically a cylinder. The cylinder, as a drive source, has the characteristics of simple structure and rapid response, enabling the heater 22 to quickly rise and fall, meeting the high efficiency requirements of automated production lines.

[0126] Of course, in other embodiments, the third drive mechanism 21 can also be any linear drive mechanism such as a hydraulic cylinder, a linear motor, or a combination of a motor and a linear drive module (such as a lead screw and nut pair or a gear and rack mechanism).

[0127] In one embodiment, the second cooling device 10 can be any one of liquid cooling device, contact heat conduction cooling device, phase change cooling device, air cooling device, etc.

[0128] See Figure 2 In one embodiment, the positioning component 4 has a positioning groove 41, which engages with the lower end of the housing stator assembly 30. The structural design of the positioning groove 41 enables rapid and precise radial positioning of the lower end of the housing stator assembly 30, eliminating positional deviations during disassembly through mechanical fitting and ensuring the alignment accuracy between the housing stator assembly 30 and the disassembly equipment. Secondly, the contour of the positioning groove 41 matches the shape of the lower end of the housing stator assembly 30, providing a self-guiding effect, facilitating quick placement of the housing stator assembly 30 by operators and automatic position correction, significantly improving production efficiency. Furthermore, the constraint effect of the positioning groove 41 effectively distributes the radial load generated during disassembly, preventing the housing stator assembly 30 from shifting or rotating under force, ensuring that the disassembly force is always transmitted axially. In addition, this design, through optimization of the groove depth and sidewall angle, provides sufficient positioning accuracy while retaining necessary assembly tolerance margins to accommodate dimensional fluctuations in different batches of workpieces.

[0129] See Figure 5 In one embodiment, the locking component 5 is provided with a second elastic contact member 56, which is used to abut against the housing 301. The introduction of the second elastic contact component 56 enables the locking assembly 5 to adapt to the dimensional tolerances and surface irregularities of the housing 301 through elastic deformation when in contact with the housing 301, ensuring a uniform distribution of locking force and avoiding localized stress concentration or deformation of the housing 301 caused by rigid contact. Secondly, the second elastic contact component 56 provides stable locking force while also having buffering and shock absorption characteristics, effectively absorbing vibrations or impacts that may occur during disassembly and protecting the surface integrity of the housing 301. Thirdly, the variability of the elastic material of the second elastic contact component 56 compensates for manufacturing and assembly errors, improves the adaptability of the equipment to housings 301 of different specifications, and reduces the process requirements for precision machining. In addition, the flexible contact between the second elastic contact component 56 and the housing 301 can also increase the coefficient of friction, prevent relative sliding during locking, and ensure that the relative position of the housing 301 and the stator 302 remains stable during disassembly. In summary, this design, through the synergistic effect of elastic contact and rigid locking mechanism, achieves protection of the workpiece surface while ensuring locking reliability.

[0130] In one embodiment, the second elastic contact member 56 can be a structure made of an elastic material, such as any one of rubber, polyurethane, etc.

[0131] See Figure 5 In one embodiment, the locking component 5 includes:

[0132] Support base 51, which is mounted on the body 1;

[0133] Locking operation component 52, the first end of which is pivotally connected to the body 1;

[0134] Linkage component 53, the first end of which is pivotally connected to the second end of locking operation component 52;

[0135] The swing arm 54 has its first end pivotally connected to the support base 51, and its second end pivotally connected to the linkage component 53; and

[0136] A locking contact component 55 is located at the third end of the swing arm 54, with the second end of the swing arm 54 situated between the third end and the first end. The locking contact component 55 abuts against the housing 301. Thus, when locking the housing 301, the operator lifts the locking operation component 52, causing it to rotate around its pivot point with the support base 51. This rotates the linkage component 53 towards the positioning component 4, pushing the second end of the swing arm 54 and forcing it to swing with its first end at the pivot point with the support base 51 as the fulcrum. At this time, the third end of the swing arm 54 moves the locking contact component 55 towards the housing stator assembly 30 located on the positioning component 4 until it tightly abuts against the surface of the housing 301, completing the locking. Because the second end of the swing arm 54 is located between the first and third ends, a lever structure is formed, allowing the operator to obtain a large axial locking force through lever arm amplification with only a small upward pushing force. When arm 54 is in its extreme position, linkage component 53 applies an upward force to swing arm 54, forming a mechanical self-locking effect, which can maintain the locked state without continuous force. When unlocking, the operator presses down on locking operation component 52, and the linkage component 53 pulls the second end of swing arm 54 in the opposite direction, causing the locking contact component 55 at the third end of swing arm 54 to move outward and disengage from the surface of housing 301. At this time, all pivot points are reset, and locking assembly 5 returns to its initial free state. During this process, the lever ratio design and pivot layout of swing arm 54 ensure the ease of unlocking operation, while the flexible contact characteristics between locking contact component 55 and housing 301 can avoid rigid impact during unlocking. The entire locking assembly 5 achieves bidirectional motion conversion through a purely mechanical structure, which has the advantages of easy operation, reliable position holding, and adaptive adjustment.

[0137] Of course, in other embodiments, the locking component 5 described above can also adopt an existing automatic locking structure, as long as it can lock and unlock the outer casing 301.

[0138] In one embodiment, the disassembly device for separating the motor housing from the stator further includes:

[0139] A filter device 20 is disposed on the body 1 and connects to the first inner cavity of the first protective cover 23. The filter device 20 is used to filter and purify the air inside the first protective cover 23 to prevent atmospheric pollution.
