Description

Technical Field

[0001] This application relates to the field of motor recycling and repair technology, and in particular to a motor stator and rotor separation device. 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 motor stators and rotors is a critical but technically complex process.

[0004] Currently, most mainstream motor stator and rotor disassembly equipment on the market employs mechanical ejection technology, such as using a cylinder or screw-driven ejection component to apply axial thrust to the rotor to achieve separation. While this type of equipment improves disassembly efficiency, it has significant drawbacks:

[0005] The aforementioned mechanical ejection technology cannot guarantee that the stator and rotor are coaxial. During the separation process, the stator and rotor will rub against each other, resulting in wear on the separated stator and rotor, which will affect recovery or maintenance. Utility Model Content

This ensures the rotor moves linearly along a precisely aligned trajectory, completely eliminating the possibility of radial misalignment during separation. This achieves non-destructive separation of the rotor and stator in a zero-friction state, significantly improving the direct recovery rate or repair qualification rate of the rotor and stator, and effectively reducing the overall cost of remanufacturing or repair.

[0059] 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.

[0060] See Figures 1-6 This invention illustrates a preferred embodiment of a motor stator-rotor separation device, comprising:

[0061] Body 1;

[0062] First locking component 2, the first locking component 2 is disposed on the machine body 1, the first locking component 2 is used to cooperate with the motor to lock the stator on the machine body 1;

[0063] Ejection drive mechanism 3 is provided on the body 1;

[0064] Ejector component 4 is connected to the output end of ejector drive mechanism 3. Ejector component 4 can move along the rotor axis of motor as the output end of ejector drive mechanism 3 moves. Ejector component 4 is used to cooperate with the first axial end of the center hole of rotor to position the first axial end of the center hole of rotor and to push rotor to move axially.

[0065] The first moving part 5 is movably disposed on the body 1, and the moving direction of the first moving part 5 is perpendicular to the moving direction of the ejector part 4.

[0066] The second moving part 6 is movably disposed on the first moving part 5, and the moving direction of the second moving part 6 is the same as the moving direction of the ejector part 4; and

[0067] Positioning component 7 is disposed on the second moving component 6. Positioning component 7 is used to cooperate with the axial second end of the center hole of the rotor to position the axial second end of the center hole of the rotor. It cooperates with the ejector component 4 to ensure that the rotor and the stator are coaxial.

[0068] This utility model's motor stator-rotor separation device integrates a body 1, a first locking component 2, an ejection drive mechanism 3, an ejection component 4, a first moving component 5, a second moving component 6, and a positioning component 7. This ensures that the rotor and stator remain coaxially aligned during the separation process, preventing frictional damage caused by axial misalignment. In specific operation, the motor is first fixed to the first locking component 2 to lock the stator position. Then, the positioning component 7 is adjusted to precisely insert into the second axial end of the rotor's central hole. Mechanical constraints forcefully correct the rotor's central axis, ensuring it completely coincides with the stator's central axis. Next, the ejection component 4 is driven to engage with the first axial end of the rotor's central hole. During ejection, the positioning component 7 and the ejection component 4 form bidirectional positioning constraints at both axial ends of the rotor, constituting a stable axial guiding system. This ensures the rotor moves linearly along a precisely aligned trajectory, completely eliminating the possibility of radial misalignment during separation. This achieves non-destructive separation of the rotor and stator in a zero-friction state, significantly improving the direct recovery rate or repair qualification rate of the rotor and stator, and effectively reducing the overall cost of remanufacturing or repair.

[0069] In this embodiment, "alignment" refers to ensuring that the central axis of the rotor coincides with the central axis of the stator during the separation process of the motor stator and rotor, that is, maintaining a coaxial state, so as to ensure that there is no friction or damage due to misalignment during separation.

[0070] Specifically, during the separation operation, since the rotor is usually nested inside the stator, if their axes are not aligned (i.e., not aligned), forced separation can easily cause friction or collision between the rotor and the inner wall of the stator, resulting in wear or even damage. Therefore, this motor stator-rotor separation device, through the coordinated cooperation of the ejection component 4 and the positioning component 7, ensures that the rotor always moves in the correct direction during the ejection process, avoiding skewness, thereby guaranteeing a smooth and damage-free separation process.

[0071] In one embodiment, the first locking component 2 includes:

[0072] Motor positioning plate 21 is detachably mounted on the machine body 1 so that the appropriate motor positioning plate 21 can be replaced according to different specifications of motor. The motor positioning plate 21 is provided with multiple positioning protrusions 211, which form a positioning groove. The positioning groove is adapted to the axial end of the motor to achieve precise positioning of the motor.

[0073] Threaded hole 22, threaded hole 22 is provided on motor positioning plate 21; and

[0074] The locking fastener (not shown in the figure) has its head abutting against the motor housing, and the rod of the locking member passes through the hole on the motor and is screwed into the threaded hole 22, so as to detachably lock the motor onto the motor positioning plate 21 and prevent the stator from moving relative to the body 1.

[0075] It is understood that the aforementioned locking device is a screw. Of course, in other embodiments, a bolt may be used instead of the aforementioned locking device.

[0076] See Figures 1-2 In one embodiment, the body 1 has a limiting part 11;

[0077] The motor stator-rotor separation equipment also includes:

[0078] The second locking component 8 is movably disposed on the first moving part 5. The second locking component 8 has a first locked state and a first unlocked state. The second locking component 8 is movable and can switch between the first locked state and the first unlocked state.

[0079] The first locking state is when the second locking component 8 is connected to the limiting part 11 to restrict the positioning component 7 to be coaxial with the rotor on the first locking component 2;

[0080] In the first unlocked state, the second locking component 8 separates from the limiting part 11, allowing the first moving part 5 to move relative to the machine body 1. The coordinated operation of the limiting part 11 and the second locking component 8 ensures both high-precision guiding reliability during rotor separation and adaptability and efficiency during equipment operation. Specifically, in the first locked state, the second locking component 8 and the limiting part 11 form a rigid constraint, ensuring that the positioning part 7 and the rotor maintain precise coaxial alignment, providing a stable axial reference for the separation process. In the unlocked state, the second locking component 8 disengages from the limiting part 11, giving the first moving part 5 freedom of movement, facilitating rapid adjustment of the initial position of the positioning part 7 to adapt to the separation requirements of motors of different specifications.

[0081] See Figure 2 In one embodiment, the limiting part 11 has a limiting hole 111. In the first locked state, at least a portion of the positioning part 7 is inserted into the limiting hole 111. Thus, by combining the mating structure of the positioning part 7 and the limiting hole 111, the limiting hole 111 forms a radial constraint on the positioning part 7 in the first locked state, ensuring that the positioning part 7 maintains a stable axial alignment reference during the separation process. This forces the correction of the coaxiality of the rotor and stator, effectively preventing frictional damage caused by positioning deviation. At the same time, the mating structure of the positioning part 7 and the limiting hole 111 has self-aligning characteristics, which can automatically compensate for assembly tolerances. While ensuring separation accuracy, it reduces the requirements for equipment debugging accuracy and improves the reliability and adaptability of the equipment.

[0082] Of course, in other embodiments, the limiting part 11 can also cooperate with the second locking component 8 through a protruding structure, as long as it can limit the second locking component 8.

[0083] See Figures 1-2 In one embodiment, the second locking component 8 includes:

[0084] A first locking screw 81 is screwed onto the first movable component 5. One end of the first locking screw 81, away from its head, can engage or disengage with the limiting part 11.

[0085] The first locking nut 82 is screwed onto the first locking screw 81 and can abut against the first moving part 5. The state switching of the second locking component 8 is achieved through the threaded engagement between the first locking nut 82 and the first locking screw 81. During operation, simply loosening the first locking nut 82 and rotating the first locking screw 81 is sufficient to complete the state transition, which has the advantage of simple operation. At the same time, the self-locking characteristic of the threaded pair is used to reliably lock the second locking component 8, which not only ensures the stable maintenance of the first locked state or the first unlocked state, but also has the advantages of simple structure and reliable locking, effectively improving the ease of operation and reliability of the equipment.

[0086] Of course, in other embodiments, the second locking component 8 can also be a linear drive mechanism such as a cylinder, hydraulic cylinder, or electric push rod. The movable end of the linear drive mechanism such as the cylinder, hydraulic cylinder, or electric push rod can cooperate with or separate from the limiting part 11. In this way, the state switching of the second locking component 8 can be achieved by controlling the movement of the movable end of the linear drive mechanism such as the cylinder, hydraulic cylinder, or electric push rod. This not only retains the original locking function but also realizes the automatic switching of the state, significantly improving the operating efficiency and reducing the need for manual intervention.

[0087] In one embodiment, the limiting part 11 is separately disposed from the body 1. The limiting part 11 is made of wear-resistant material to improve the wear resistance of the mating surface between the limiting part 11 and the second locking component 8, thereby ensuring that the positioning component 7 maintains accurate centering function for a long time, effectively extending the service life of the equipment and maintaining stable separation accuracy. At the same time, since the limiting part 11 is separately disposed from the body 1, it is convenient to replace the limiting part 11 separately after wear, thereby reducing maintenance costs.

[0088] See Figures 1-2 In one embodiment, the motor stator-rotor separation device further includes:

[0089] The third locking component 9 is movably disposed on the second moving part 6. The third locking component 9 has a second locked state and a second unlocked state. The third locking component 9 is movable and can switch between the second locked state and the second unlocked state.

[0090] The second locking state is that the third locking component 9 is connected to the body 1 to restrict the movement of the second moving part 6;

[0091] The second unlocked state involves the separation of the third locking component 9 from the body 1, allowing the second moving component 6 to move relative to the body 1. After separation, the second moving component 6 is moved away from the rotor until the positioning component 7 disengages from the rotor. Then, the third locking component 9, in conjunction with the body 1, locks the second moving component 6, maintaining the positioning component 7 stably in the position detached from the rotor. The rotor is then manually moved away from the ejector component 4. This process ensures smooth, interference-free rotor removal and, by replacing manual handling with the third locking component 9, effectively improves operational safety and transfer efficiency, while avoiding the risk of displacement of the positioning component 7 due to manual intervention.

[0092] See Figure 2 In one embodiment, the third locking component 9 includes:

[0093] The second locking screw 91 is screwed onto the second moving part 6, and the end of the second locking screw 91 opposite to its head can engage or disengage from the body 1; and

[0094] The second locking nut 92 is screwed onto the second locking screw 91 and can abut against the second moving part 6. The state switching of the third locking component 9 is achieved through the threaded engagement between the second locking nut 92 and the second locking screw 91. During operation, simply loosening the second locking nut 92 and rotating the second locking screw 91 is sufficient to complete the state transition, which has the advantage of simple operation. At the same time, the self-locking characteristic of the threaded pair is used to reliably lock the third locking component 9, which not only ensures the stable maintenance of the second locked state or the second unlocked state, but also has the advantages of simple structure and reliable locking, effectively improving the ease of operation and reliability of the equipment.

[0095] Of course, in other embodiments, the third locking component 9 can also be a linear drive mechanism such as a cylinder, hydraulic cylinder, or electric push rod. The movable end of the linear drive mechanism such as the cylinder, hydraulic cylinder, or electric push rod can cooperate with or separate from the limiting part 11. In this way, the state switching of the third locking component 9 can be achieved by controlling the movement of the movable end of the linear drive mechanism such as the cylinder, hydraulic cylinder, or electric push rod. This not only retains the original locking function but also realizes the automatic switching of the state, significantly improving the operating efficiency and reducing the need for manual intervention.

[0096] See Figure 1 In one embodiment, the motor stator-rotor separation device further includes:

[0097] The first guide component 10 is mounted on the machine body 1 and extends along the moving direction of the first moving component 5. The first moving component 5 and the first guide component 10 are slidably engaged. Thus, through the sliding engagement structure between the first guide component 10 and the first moving component 5, a precise linear motion trajectory is provided for the moving component, ensuring that the positioning component 7 maintains a stable direction of motion during movement. This effectively improves the positioning accuracy and operational stability of the rotor centering operation. At the same time, this guide structure is simple and reliable, easy to assemble and maintain, and provides a basic guarantee for the long-term stable operation of the equipment.

[0098] The second guide component 20 is disposed on the first moving component 5 and extends along the moving direction of the second moving component 6. The second moving component 6 and the second guide component 20 are slidably engaged. In this way, the sliding engagement structure between the second guide component 20 and the second moving component 6 provides a precise linear motion trajectory for the moving component, ensuring that the positioning component 7 maintains a stable direction of motion during the movement process. This effectively improves the positioning accuracy and running stability of the rotor centering operation. At the same time, the guide structure is simple and reliable, easy to assemble and maintain, and provides a basic guarantee for the long-term stable operation of the equipment.

[0099] In one embodiment, both the first moving component 5 and the second moving component 6 are sliders, and correspondingly, both the first guiding component 10 and the second guiding component 20 are guide rails.

[0100] Of course, in other embodiments, the first moving part 5 and the second moving part 6 can both be guide sleeves, and correspondingly, the first guiding part 10 and the second guiding part 20 can both be guide rods.

[0101] See Figures 1-2 In one embodiment, the motor stator-rotor separation device further includes:

[0102] The first connecting seat 30 is disposed on the first moving part 5 and supports the second guide part 20.

[0103] The second connecting seat 40 is disposed on the second moving part 6 and supports the positioning part 7.

[0104] See Figure 1 and Figure 6 In one embodiment, the positioning component 7 includes:

[0105] A first connector 71 is disposed on the second movable component 6; and

[0106] The centering positioning component 72 is detachably mounted on the first connecting component 71 and is used to mate with the axial second end of the rotor's center hole. By detachably mounting the centering positioning component 72 on the first connecting component 71, it can be disassembled and reassembled, enabling rapid adaptation to rotors of different specifications. Equipment adjustments can be completed simply by replacing the centering positioning component 72 of the appropriate specification, significantly improving the equipment's versatility and operational efficiency. Simultaneously, this split design facilitates independent maintenance and replacement of the centering positioning component 72, reducing equipment maintenance costs. Furthermore, because the centering positioning component 72 mates with the axial second end of the rotor's center hole, the centering accuracy requirement is concentrated in the centering positioning component 72, ensuring precise centering during rotor separation while avoiding the need for high-precision machining of the overall structure, effectively controlling manufacturing costs while ensuring equipment performance.

[0107] See Figure 1 and Figure 6 In one embodiment, the centering positioning member 72 has a centering guide portion 721. The cross-section of the centering guide portion 721 gradually increases in the direction away from the first locking component 2, that is, the centering guide portion 721 has a tapered structure. The centering guide portion 721 is used to guide the centering positioning member 72 into the center hole of the rotor. Thus, when the centering positioning member 72 is inserted into the center hole of the rotor, the tapered centering guide portion 721 guides the centering positioning member 72 into the center hole of the rotor, realizing automatic guidance and centering correction, effectively reducing the assembly positioning accuracy requirements. At the same time, the tapered centering guide portion 721 can adaptively compensate for the center hole position deviation of rotors of different specifications, ensuring fast and accurate centering positioning. This significantly improves the convenience of equipment operation, enhances the reliability of the positioning process, reduces the need for manual intervention, and improves the consistency and efficiency of separation operations.

[0108] Of course, in other embodiments, the specific structure of the centering positioning member 72 can also be adapted to different rotor structures.

[0109] See Figure 6 In one embodiment, the first connector 71 has a first connecting hole and a second connecting hole 711, the first connecting hole extending axially along the first connector 71, the second connecting hole 711 extending radially along the first connector 71, and the second connecting hole 711 communicating with the first connecting hole.

[0110] The centering positioning member 72 is provided with a first connecting part 722, which is adapted to a first connecting hole. The first connecting part 722 has a third connecting hole 723. When the first connecting part 722 is inserted into the first connecting hole, the third connecting hole 723 communicates with the second connecting hole 711.

[0111] Positioning component 7 also includes:

[0112] The first fastener has a head that abuts against the first connector 71, and a shank that passes through the second connecting hole 711 and is screwed into the third connecting hole 723; that is, the first fastener is a screw. Thus, the first connecting part 722 and the first connecting hole form an axial insertion structure, which provides an initial positioning reference. Simultaneously, the first fastener connects the second connecting hole 711 and the third connecting hole 723 to form a radial fastening structure, which provides reliable locking. Therefore, the coordinated cooperation of the axial insertion structure and the radial fastening structure not only enables the quick assembly and disassembly of the centering positioning part 72 but also provides multi-directional limiting to ensure connection stability.

[0113] Of course, in other embodiments, bolts or locating pins can be used instead of the first fastener described above.

[0114] See Figures 3-5 In one embodiment, the ejector component 4 includes:

[0115] The second connector 41 is connected to the output end of the ejection drive mechanism 3; and

[0116] The ejector positioning component 42 is detachably mounted on the second connecting component 41 and is used to mate with the axial first end of the rotor's center hole. By detachably mounting the ejector positioning component 42 on the second connecting component 41, it can be easily disassembled, enabling rapid adaptation to rotors of different specifications. Equipment adjustment can be completed simply by replacing the ejector positioning component 42 of the appropriate specification, significantly improving the equipment's versatility and operational efficiency. Simultaneously, this split design facilitates independent maintenance and replacement of the ejector positioning component 42, reducing equipment maintenance costs. Furthermore, because the ejector positioning component 42 mates with the axial first end of the rotor's center hole, the alignment accuracy requirement is concentrated on the ejector positioning component 42, ensuring precise alignment during rotor separation while avoiding the need for high-precision machining of the overall structure, effectively controlling manufacturing costs while ensuring equipment performance.

[0117] See Figures 3-5 In one embodiment, the ejector positioning member 42 has a positioning part and a supporting part. The positioning part is adapted to fit the axial first end of the center hole of the rotor to position the axial first end of the center hole of the rotor. The supporting part is provided on the outer peripheral wall of the positioning part and is arranged around the positioning part. The outer diameter of the supporting part is larger than the diameter of the center hole of the rotor. The supporting part is used to abut against the axial first end of the rotor so as to drive the rotor to move axially.

[0118] Of course, in other embodiments, the specific structure of the ejector positioning member 42 can also be adapted to different rotor structures.

[0119] See Figure 5 In one embodiment, the second connector 41 has a fourth connecting hole 411 and a fifth connecting hole 412, the fourth connecting hole 411 extending axially along the second connector 41, the fifth connecting hole 412 extending radially along the second connector 41, and the fifth connecting hole 412 communicating with the fourth connecting hole 411.

[0120] The ejector positioning member 42 is provided with a second connecting part 421, which is adapted to the fourth connecting hole 411. The second connecting part 421 has a sixth connecting hole 422. When the second connecting part 421 is inserted into the fourth connecting hole 411, the sixth connecting hole 422 communicates with the fifth connecting hole 412.

[0121] Positioning component 7 also includes:

[0122] The second fastener has a head that abuts against the second connector 41, and a shank that passes through the fifth connecting hole 412 and is screwed into the sixth connecting hole 422, meaning the second fastener is a screw. Thus, the second connecting part 421 and the fourth connecting hole 411 cooperate to form an axial insertion structure, which provides an initial positioning reference. Simultaneously, the second fastener connects the fifth connecting hole 412 and the sixth connecting hole 422 to form a radial fastening structure, achieving reliable locking. Therefore, the coordinated cooperation of the axial insertion structure and the radial fastening structure not only enables the quick assembly and disassembly of the ejector positioning part 42 but also provides multi-directional limiting to ensure connection stability.

[0123] Of course, in other embodiments, bolts or locating pins can be used instead of the second fastener described above.

[0124] See Figures 3-4 In one embodiment, the ejection drive mechanism 3 includes:

[0125] A rotating shaft 31 is rotatably mounted on the machine body 1;

[0126] Turntable 32 is mounted on rotating shaft 31 and is used for hand gripping;

[0127] Lead screw 33 is rotatably mounted on machine body 1, and lead screw 33 is perpendicular to rotating shaft 31;

[0128] The active bevel gear 34 is connected to the rotating shaft 31 and can rotate with the rotating shaft 31.

[0129] Driven bevel gear 35 meshes with driving bevel gear 34, and is connected to lead screw 33; and

[0130] A movable nut 36 is sleeved on the lead screw 33 and can move axially along the lead screw 33 as the lead screw 33 rotates. The movable nut 36 is connected to the ejector component 4. Through the combined transmission design of the rotating shaft 31, turntable 32, bevel gear set, and lead screw 33 nut mechanism, precise force amplification and motion conversion for manual operation are achieved. The bevel gear set effectively solves the problem of spatial direction conversion, allowing the operator to apply force in a comfortable position. At the same time, the lead screw 33 nut mechanism converts rotational motion into precise linear ejection action, ensuring both the controllability and stability of the ejection force, and ensuring reliable maintenance of the ejection position through mechanical self-locking characteristics. The overall structure is compact and has high transmission efficiency, achieving both convenient manual operation and meeting the process requirements of precision ejection operations.

[0131] Of course, in other embodiments, the ejection drive mechanism 3 may consist only of a turntable 32, a lead screw 33, and a movable nut 36.

[0132] See Figures 3-4 In one embodiment, the ejection drive mechanism 3 further includes:

[0133] The third guide component 37 is disposed on the body 1 and extends along the moving direction of the ejector component 4.

[0134] The third moving component 38 is slidably mounted on the third guide component 37 and connected to the ejector component 4. Thus, the sliding engagement between the third guide component 37 and the third moving component 38 provides precise linear motion guidance for the ejector component 4, ensuring that the force transmission direction remains strictly axially aligned during ejection, effectively preventing ejection deviation. Simultaneously, this guiding structure enhances the rigidity and motion stability of the ejection system, ensuring both smooth and reliable rotor separation and improved ejection positioning accuracy. The overall structure is simple and compact, and its operation is reliable and durable.

[0135] In one embodiment, the motor stator-rotor separation device further includes:

[0136] The third connecting seat 50 is disposed on the third moving part 38. The third connecting seat 50 is connected to the moving nut 36 and supports the ejector part 4.

[0137] The fourth connecting seat 60 is mounted on the body 1 and supports the rotating shaft 31, the driving bevel gear 34, the driven bevel gear 35, and the third guide component 37. Thus, the arrangement of the third connecting seat 50 and the fourth connecting seat 60 enables the ejector drive mechanism 3 and the ejector component 4 to form a modular structure, facilitating their installation and maintenance.

[0138] See Figure 1 In one embodiment, the motor stator-rotor separation device further includes:

[0139] A guide sleeve 70 is mounted on the machine body 1. The ejector component 4 slidably passes through the central hole of the guide sleeve 70 to guide its movement. Thus, the sliding fit between the guide sleeve 70 and the ejector component 4 provides precise axial guidance for the ejection action, ensuring that the ejection force is transmitted strictly along the axial direction and effectively preventing radial deviation during the ejection process. Furthermore, this guide structure is simple, reliable, and easy to maintain, ensuring both the smoothness and positioning accuracy of the rotor separation process and improving the reliability and service life of the equipment.
