Description

Technical Field

[0001] This invention belongs to the field of motor manufacturing, specifically a rotor sealing machine based on the production of new energy vehicle motors. Background Technology

[0002] The electric motor is the core power component of electric vehicles, responsible for converting electrical energy into mechanical energy to drive the wheels. As the rotating part of the motor, the rotor needs to have high magnetic energy product, low loss and good mechanical strength, which directly affects the power density, efficiency and range of the motor and the overall vehicle.

[0003] Rotor tapering is a key process in motor rotor manufacturing. It is mainly used to fix permanent magnets or conductor bars and prevent them from shifting or falling off during high-speed rotation. Through mechanical stamping or hot pressing, the outer retaining ring or end ring material of the rotor is squeezed and gathered towards the center to form a strong locking structure. This process can improve the dynamic balance accuracy and reliability of the rotor, reduce vibration and noise, and ensure the safe and stable operation of the motor at high speeds. Traditional rotor sealing machines often use a direct bonding extrusion method to press and reset the protrusions on the surface of the rotor core. The overall process is relatively rough and can easily cause problems such as overall deformation or out-of-roundness of the rotor core, affecting the quality of the finished product. At the same time, it is impossible to inspect the sealing quality in time after sealing is completed. It is necessary to transfer to other inspection equipment for inspection, which affects production efficiency.

[0004] Therefore, the present invention provides a rotor sealing machine based on the production of new energy vehicle motors. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0006] The technical solution adopted by the present invention to solve its technical problem is as follows: The present invention provides a rotor closing machine based on the production of new energy vehicle motors, including two support platforms arranged opposite to each other. The end of the support platform is equipped with a clamp for fixing the rotor module. The support platform can drive the clamp to rotate. A closing roller that can rotate is arranged above the support platform. Both ends of the closing roller are provided with lifting rails for driving the closing roller to rise and fall. This setup not only enables the motor rotor to be closed, but also ensures that the surface contour of the extruded rotor module is perfectly smooth and cylindrical by using rolling extrusion, thus improving the quality of the finished product. Furthermore, the multi-layer progressive extrusion method disperses the extrusion force, prevents warping, and improves accuracy. It also includes a final product inspection function. Because it is integrated into the closing equipment, the subsequent transfer and inspection process is shortened, production efficiency is improved, and while ensuring the quality of the finished product, the defect rate of the product leaving the factory is also reduced.

[0007] Preferably, the support platform includes a power box, the clamp is installed at the end of the power box, and the bottom of the power box is provided with a moving rail for driving the power box to move horizontally. During operation, in order to facilitate the installation and removal of the rotor module, the two power boxes are moved horizontally synchronously through the moving rail, so that the support platform can carry the rotor module that has been closed out from under the closing roller, making it convenient to disconnect and take it out, and then put in the rotor module that is ready to be closed out for subsequent closing work.

[0008] Preferably, a rotating platform is slidably engaged on the outer side of the clamp, and the rotating end of the power box is driven to the rotating platform. The rotating platform is driven to the rotor core of the rotor module via a contact arm. During operation, the rotation completed by driving the rotor module's drive shaft will exert force between the drive shaft and the rotor core. However, the force of metal extrusion and closing is relatively large, which can easily affect the connection between the drive shaft and the rotor core. By using the contact arm to contact the surface of the rotor core, and with two independent drive devices built into the power box to drive the clamp and the rotating platform to rotate, the force is transmitted to the rotor core through the rotation of the rotating platform, completing the rotation of the entire rotor module. The clamp can also rotate passively to assist in the rotation process. With this configuration, the rotational force of the rotor module is directly transmitted to the rotor core, and the reaction force is also directly applied to the connection between the contact arm and the rotor core, thus not affecting the connection between the drive shaft and the rotor core, ensuring that the rotor module is not damaged during the closing process.

[0009] Preferably, the surface of the rotary table is provided with an inclined connecting groove, in which a connecting arm is threadedly connected. Multiple connecting arms are arranged in a ring at equal intervals. A transmission head is fixed to the rear end of each connecting arm, and the transmission head is connected to a contact arm. During operation, the inclined connecting groove allows the connecting arm to drive the contact arm to horizontally press the rotor core as it approaches the rotor module. The additional connecting arms allow the contact arm to avoid the position of the clamp, and the inclined connecting arms also have greater adjustment space. Specifically, the adjustment method is to control the rotation and movement of the connecting arm by rotating the transmission head at the end of the connecting arm with a tool, so that the end of the connecting arm is inclined and close to the rotor module. Since the connecting arm is connected to the contact arm, it will also horizontally press towards the rotor module, allowing the rotational force of the rotary table to be smoothly transmitted.

[0010] Preferably, the bottom end of the connecting arm is rotatably connected to a docking platform. The surface of the docking platform has a horizontally set connecting groove II. The contact arm is connected to the docking platform through the connecting groove II. During operation, the docking platform and the connecting arm are rotatably connected. When the connecting arm rotates, the contact arm can remain relatively stationary and does not rotate. It only pushes the contact arm to be pressed against the rotor core in an inclined direction, ensuring that the power can be transmitted smoothly. The contact arm can be long rod-shaped and can be directly inserted into the counterweight hole on the rotor core. If there is no counterweight hole or other hole that can be inserted, the contact arm can be directly pressed and fixed to the surface of the rotor core. The contact arm always remains in a horizontal state, ensuring the smooth transmission of power after being tilted and pressed down.

[0011] Preferably, the docking platform is spherical, with a binding groove in the center. Synchronizing rings are fitted around the outer sides of multiple docking platforms. During operation, the spherical shape of the docking platform allows for compatibility with different types of contact arms. The docking platform itself can also be detached from the connecting arm, allowing the connecting arm to be pulled out of the rotary table. After all the synchronizing rings are fixed, all docking platforms are locked together, further ensuring that the force of the rotary table is transmitted to the contact arm and rotor module. The synchronizing ring can be a wound steel cable or other lockable components. The binding groove can be on the surface or a perforated design to ensure the locking of the docking platforms.

[0012] Preferably, the end of the contact arm is provided with a detachable friction head, the surface of the friction head is provided with a friction layer for increasing friction, and the surface of the friction head is provided with an adsorption component. During operation, when there are no holes on the surface of the rotor core for fixing, the friction head is installed at the end of the contact arm. As the contact arm tilts down and presses against the surface of the rotor core, the friction layer can provide huge friction force, ensuring that the rotor module rotates normally under force transmission. The adsorption component can be a magnetic adsorption component or a negative pressure adsorption component, which further improves the connection force.

[0013] Preferably, the moving rail is segmented, with the segment located between two lifting rails. A separating rail is provided at the segment of the two moving rails. The bottom of the separating rail is provided with a misaligned rail for driving the separating rail to move horizontally. The top of the misaligned rail is also provided with a closing roller two that moves synchronously with the separating rail. During operation, when closing is required, the upper and lower rollers can be used to squeeze synchronously. After the rotor module moves into position, the separating rail is controlled to move away, allowing the closing roller two to move directly below the closing roller one. The closing roller two can also move up and down. During the closing operation, the closing roller one and the closing roller two squeeze the rotor module synchronously from top to bottom, which not only doubles the working efficiency, but also prevents the rotor module from being subjected to excessive downward squeezing force due to the offsetting of the upper and lower forces, thus ensuring the safe processing of the rotor module.

[0014] Preferably, a flat platform is installed at the moving end of the separating rail. The side of the flat platform is fixedly connected to the separating rail, and two lifting platforms for controlling the lifting and lowering of the second closing roller are fixedly connected to the top of the flat platform. During operation, the lifting and lowering of the second closing roller is controlled by the lifting platforms, and the flat platform and the separating rail move synchronously to ensure the normal process of rail repositioning.

[0015] Preferably, the end of the closing roller is connected to a connecting arm, the lifting rails are distributed on the top of the connecting arm near both sides, and a detection module is fixed in the middle of the connecting arm. During operation, the bending state of the connecting arm can ensure that the rotor module moves smoothly without collision, while the two lifting rails ensure the stable lifting of the connecting arm. The detection module can detect the reaction force of the rotor module on the closing roller after the connecting arm is fixed at a certain height, thus realizing the function of finished product detection.

[0016] The beneficial effects of this invention are as follows: 1. The rotor closing machine for new energy vehicle motor production described in this invention, through the setting of closing roller one, not only realizes the closing work of the motor rotor, but also uses rolling extrusion to ensure that the surface contour of the extruded rotor module presents a perfectly smooth cylindrical shape, improving the quality of the finished product. Furthermore, the multi-layer progressive extrusion method disperses the extrusion force, prevents warping and improves accuracy. It also includes a final product inspection function. Since it is integrated into the closing equipment, it shortens the subsequent transfer and inspection process, improves production efficiency, ensures the quality of the finished product, and reduces the defect rate of the product leaving the factory.

[0017] 2. The rotor closing machine based on the production of new energy vehicle motors described in this invention can use two rollers to extrude synchronously. After the rotor module is moved into place, the separation rail is controlled to move away, allowing the second closing roller to move directly below the first closing roller. The second closing roller can also be raised and lowered. During the closing operation, the first and second closing rollers extrude the rotor module synchronously, one above the other, which not only doubles the working efficiency, but also prevents the rotor module from being subjected to excessive downward extrusion force due to the offsetting of the upper and lower forces, thus ensuring the safe processing of the rotor module.

[0020] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0021] like Figures 1 to 8 As shown in the embodiment of the present invention, a rotor closing machine based on the production of new energy vehicle motors includes two opposing support platforms 5. The end of the support platform 5 is equipped with a clamp 14 for fixing the rotor module 2. The support platform 5 can drive the clamp 14 to rotate. A closing roller 3 that can rotate is provided above the support platform 5. Both ends of the closing roller 3 are provided with lifting rails 6 for driving the closing roller 3 to rise and fall. Two support platforms 5 are used to horizontally fix the rotor module 2 that needs to be closed. Two clamps 14 are used to fix the drive shaft portions at both ends of the rotor module 2. The closing roller 3 is controlled to sink, allowing its surface to contact the rotor core of the rotor module 2. The diameter of the closing roller 3 is smaller than the outer diameter of the rotor core. The support platforms 5 drive the clamps 14 to rotate, which in turn drives the rotor module 2 to rotate. As the rotation proceeds, the outward-protruding "horns" of the rotor core will contact and press against the closing roller 3, causing the outward-protruding part to be compressed into an inward-curving arc shape, thus preventing the internal windings from easily coming off. (Specific steps...) This can be optimized as follows: When the closing roller 3 is under pressure during rotation, it first moves upward a certain distance to perform the first full-process compression on the convex part. After completion, the rotor module 2 rotates, allowing the closing roller 3 to return to the initial compression position and tightly adhere to the outside of the rotor core. Simultaneously, the rotor module 2 is controlled to rotate, allowing the closing roller 3 to perform a second compression on the convex part. During the second compression, the closing roller 3 compresses completely according to the arc shape of the rotor core's exterior, ensuring that the convex part is completely compressed and formed. Finally, the rotor module 2 is rotated again to return to its original position for a third re-compression operation. Through these three compression operations... This not only effectively disperses the enormous stress originally borne by one-time molding, preventing the iron core from deforming or becoming out of round due to excessive force, but also, with multi-station gradual deformation, significantly reduces metal springback, ensuring stable closing shape. Furthermore, alternating forward and reverse indexing eliminates accumulated errors caused by mechanical clearances, ensuring consistent closing height for each slot, thus improving closing quality. During each closing extrusion, the distance between the closing roller 3 and the rotor module 2 is controlled by the lifting rail 6, ensuring smooth extrusion. During extrusion, the closing roller 3 rotates with the rotor module 2, ensuring smooth extrusion. Once all the protrusions are in place, the rotor module 2 is controlled by the support platform 5 to rotate at a constant speed. At this time, the closing roller 3 is in contact with the surface of the rotor module 2, and the lifting rail 6 locks the height of the closing roller 3. The rotation speed can be appropriately increased. During the rotation, the closing roller 3 can not only press the outer surface of the rotor core for the last time to ensure that the outer surface of the rotor core presents a perfectly smooth cylindrical shape, but also integrate a pressure-sensitive module in the closing roller 3. It can detect whether there are large pressure fluctuations during the rotation process, thereby detecting the closing quality and recording the position. The position with large fluctuations can be repressed. This setup not only enables the motor rotor to be closed, but also ensures that the surface contour of the extruded rotor module 2 is perfectly smooth and cylindrical by using rolling extrusion, thus improving the quality of the finished product. Furthermore, the multi-layer progressive extrusion method disperses the extrusion force, prevents warping, and improves accuracy. It also includes a final product inspection function. Since it is integrated into the closing equipment, the subsequent transfer and inspection process is shortened, production efficiency is improved, and while ensuring the quality of the finished product, the defect rate of the product leaving the factory is also reduced.

[0022] The support platform 5 includes a power box 13, the clamp 14 is installed at the end of the power box 13, and the bottom of the power box 13 is provided with a moving rail 1 for driving the power box 13 to move horizontally. During operation, in order to facilitate the installation and removal of rotor module 2, the two power boxes 13 are moved synchronously by the moving rail 1, so that the support platform 5 can carry the rotor module 2 that has been closed out from under the closing roller 3, so as to facilitate disconnection and removal, and then put the rotor module 2 that is ready to be closed in for subsequent closing work.

[0023] The outer side of the clamp 14 is slidably engaged with the rotary table 15, the rotating end of the power box 13 is connected to the rotary table 15 in a transmission connection, and the rotary table 15 is connected to the rotor core of the rotor module 2 in a transmission connection through the contact arm 18. During operation, the rotation of the drive shaft of rotor module 2 is achieved by applying force between the drive shaft and the rotor core. However, the force of metal extrusion and closing is relatively large, which can easily affect the connection between the drive shaft and the rotor core. By using contact arm 18 to contact the surface of the rotor core, and with two independent drive devices built into the power box 13 to drive the clamp 14 and the rotary table 15 to rotate, the force is transmitted to the rotor core through the rotation of the rotary table 15, completing the rotation of the entire rotor module 2. The clamp 14 can also rotate passively to assist in the rotation process. With this setting, the rotational force of rotor module 2 is directly transmitted to the rotor core, and the reaction force is also directly applied to the connection between contact arm 18 and rotor core, thus not affecting the connection between the drive shaft and rotor core, ensuring that rotor module 2 is not damaged during the closing process.

[0024] The surface of the rotary table 15 is provided with an inclined connecting groove. A connecting arm 17 is threaded into the connecting groove. Multiple connecting arms 17 are arranged in a ring at equal intervals. A transmission head 20 is fixed to the rear end of the connecting arm 17. The transmission head 20 is connected to the contact arm 18. During operation, the inclined connecting slot allows the connecting arm 17 to move closer to the rotor module 2, and also drives the contact arm 18 to horizontally press the rotor core. The additional connecting arm 17 allows the contact arm 18 to avoid the position of the clamp 14, and the inclined connecting arm 17 also has a larger adjustment range. The specific adjustment method is to control the rotation and movement of the connecting arm 17 by rotating the transmission head 20 at the end of the connecting arm 17 with a tool, so that the end of the connecting arm 17 is inclined closer to the rotor module 2. The connecting arm 17 is connected to the contact arm 18 and will also horizontally press towards the rotor module 2, so that the rotation force of the rotary table 15 can be smoothly transmitted.

[0025] The bottom end of the linkage arm 17 is rotatably connected to the docking platform 22. The surface of the docking platform 22 is provided with a horizontally arranged connecting groove 2. The contact arm 18 is connected to the docking platform 22 through the connecting groove 2. During operation, the docking platform 22 is rotatably connected to the connecting arm 17. When the connecting arm 17 rotates, it can remain relatively stationary and does not rotate. It only pushes the contact arm 18 to be pressed against the rotor core in an inclined direction, ensuring that the power can be transmitted smoothly. The contact arm 18 can be long rod-shaped and can be directly inserted into the counterweight hole on the rotor core. If there is no counterweight hole or other hole to insert into, the contact arm 18 can be directly pressed and fixed to the surface of the rotor core. The contact arm 18 always remains in a horizontal state, ensuring the smooth transmission of power after being tilted and pressed down.

[0026] The docking platform 22 is spherical, and a binding groove 21 is provided in the center of the docking platform 22. A synchronization ring 16 is sleeved on the outer side of the plurality of docking platforms 22. During operation, the spherical design of the docking platform 22 allows it to be adapted to different models of contact arms 18. The docking platform 22 itself can also be detached from the connecting arm 17, allowing the connecting arm 17 to be pulled out from the rotary table 15. After all the synchronizing rings 16 are fixed, all docking platforms 22 are locked by the synchronizing rings 16, further ensuring that the force of the rotary table 15 is transmitted to the contact arms 18 and the rotor module 2. The synchronizing rings 16 can be wound steel cables or other lockable components. The binding groove 21 can be opened on the surface or be a perforated design to ensure the locking of the docking platform 22.

[0027] The end of the contact arm 18 is provided with a detachable friction head 19, the surface of the friction head 19 is provided with a friction layer for increasing friction, and the surface of the friction head 19 is provided with an adsorption element. During operation, when there are no holes on the surface of the rotor core that can be fixed, a friction head 19 is installed at the end of the contact arm 18. As the contact arm 18 tilts and presses down to press against the surface of the rotor core, the friction layer can provide huge frictional force, ensuring that the rotor module 2 rotates normally under the force transmission. The adsorption component can be a magnetic adsorption component or a negative pressure adsorption component, which further improves the connection force.

[0028] The moving rail 1 is segmented, with the segmentation point of the moving rail 1 located between two lifting rails 6. A separating rail 9 is provided at the segmentation point of the two moving rails 1. A misaligned rail 4 is provided at the bottom of the separating rail 9 to drive the separating rail 9 to move horizontally. A closing roller 10 that moves synchronously with the separating rail 9 is also provided at the top of the misaligned rail 4. During operation, when the end needs to be closed, the upper and lower rollers can be used to squeeze synchronously. After the rotor module 2 moves into place, the separation rail 9 is controlled to move away, allowing the closing roller 2 10 to move directly below the closing roller 1 3. The closing roller 2 10 can also be raised and lowered. During the closing operation, the closing roller 1 3 and the closing roller 2 10 squeeze the rotor module 2 synchronously, one up and one down. This not only doubles the working efficiency, but also prevents the rotor module 2 from being subjected to excessive downward squeezing force due to the offsetting of the upper and lower forces, thus ensuring the safe processing of the rotor module 2.

[0029] The moving end of the separating rail 9 is equipped with a flat platform 11. The side of the flat platform 11 is fixedly connected to the separating rail 9. The top of the flat platform 11 is fixedly connected to two lifting platforms 12 for controlling the lifting and lowering of the closing roller 10. During operation, the lifting and lowering of the closing roller 10 is controlled by the lifting platform 12, and the flat platform 11 and the separating rail 9 move synchronously to ensure the normal process of rail repositioning.

[0030] The end of the closing roller 3 is connected to a connecting arm 7, the lifting rails 6 are distributed on the top of the connecting arm 7 on both sides, and the detection module 8 is fixedly connected to the middle of the connecting arm 7. During operation, the bending state of the connecting arm 7 ensures that the rotor module 2 moves smoothly without collision, while the two lifting rails 6 ensure the stable lifting of the connecting arm 7; the detection module 8 can detect the reaction force of the rotor module 2 on the closing roller 3 after the connecting arm 7 is fixed at a certain height, thus realizing the function of finished product detection.

[0031] During operation, two support platforms 5 are used to horizontally fix the rotor module 2 that needs to be closed. Two clamps 14 are used to fix the drive shaft portions at both ends of the rotor module 2. The closing roller 3 is controlled to sink, allowing its surface to contact the rotor core of the rotor module 2. The diameter of the closing roller 3 is smaller than the outer diameter of the rotor core. The support platforms 5 drive the clamps 14 to rotate, which in turn drives the rotor module 2 to rotate. As the rotation continues, the outward-protruding "horns" of the rotor core contact and press against the closing roller 3, causing the outward-protruding parts to be compressed into an inward-curving arc shape, thus preventing the internal windings from easily coming off. The process can be optimized as follows: When the closing roller 3 is under pressure during rotation, it first moves upward a certain distance to perform the first full-process extrusion on the convex part. After completion, the rotor module 2 rotates, allowing the closing roller 3 to return to the initial extrusion position and tightly adhere to the outside of the rotor core. Simultaneously, the rotor module 2 is controlled to rotate, allowing the closing roller 3 to perform a second extrusion on the convex part. During the second extrusion, the closing roller 3 extrudes completely according to the arc shape of the rotor core, ensuring that the convex part is completely extruded and formed. Finally, the rotor module 2 is rotated again to return to its original position for the third re-extrusion operation. Through three extrusion operations... This process not only effectively distributes the enormous stress that would otherwise be borne by a single forming process, preventing the iron core from deforming or becoming out of round due to excessive force, but also, with multi-station gradual deformation, significantly reduces metal springback, ensuring a stable closing shape. Furthermore, alternating forward and reverse indexing eliminates accumulated errors caused by mechanical clearances, guaranteeing consistent closing height for each slot and thus improving closing quality. During each closing extrusion, the distance between the closing roller 3 and the rotor module 2 is controlled by the lifting rail 6, ensuring a smooth extrusion process. During extrusion, the closing roller 3 rotates with the rotor module 2, ensuring the extrusion... Smoothly, once all the protrusions are squeezed into place, the rotor module 2 is controlled by the support platform 5 to rotate at a uniform speed. At this time, the closing roller 3 is in contact with the surface of the rotor module 2, and the lifting rail 6 locks the height of the closing roller 3. The rotation speed can be appropriately increased. During the rotation, the closing roller 3 can not only re-press the outer surface of the rotor core for the last time to ensure that the outer surface of the rotor core presents a perfectly smooth cylindrical shape, but also integrate a pressure-sensitive module in the closing roller 3. It can detect whether there are large pressure fluctuations during the rotation process, thereby detecting the closing quality and recording the position. The position with large fluctuations can be re-pressed. This setup not only enables the motor rotor to be closed, but also ensures that the surface contour of the extruded rotor module 2 is perfectly smooth and cylindrical by using rolling extrusion, thus improving the quality of the finished product. Furthermore, the multi-layer progressive extrusion method disperses the extrusion force, prevents warping, and improves accuracy. It also includes a final product inspection function. Since it is integrated into the closing equipment, the subsequent transfer and inspection process is shortened, production efficiency is improved, and while ensuring the quality of the finished product, the defect rate of the product leaving the factory is also reduced.

[0032] To facilitate the installation and removal of rotor module 2, the two power boxes 13 are moved synchronously via the moving rail 1, allowing the support platform 5 to carry the rotor module 2, which has been closed, out from under the closing roller 3. This facilitates disconnection and removal, and then the rotor module 2, which is ready to be closed, is placed in for subsequent closing work.

[0033] The rotation achieved by driving the drive shaft of rotor module 2 exerts force between the drive shaft and the rotor core. However, the force exerted during metal extrusion and closing is relatively large, which can easily affect the connection between the drive shaft and the rotor core. By using contact arm 18 to contact the surface of the rotor core, and with two independent drive devices built into the power box 13 to drive the clamp 14 and the rotary table 15 to rotate, the force is transmitted to the rotor core through the rotation of the rotary table 15, completing the rotation of the entire rotor module 2. The clamp 14 can also rotate passively to assist in the rotation process. With this configuration, the rotational force of rotor module 2 is directly transmitted to the rotor core, and the reaction force is also directly applied to the connection between contact arm 18 and the rotor core, thus not affecting the connection between the drive shaft and the rotor core, ensuring that rotor module 2 is not damaged during the closing process.

[0034] The inclined connecting groove allows the connecting arm 17 to drive the contact arm 18 to horizontally press the rotor core as it approaches the rotor module 2. The additional connecting arm 17 allows the contact arm 18 to avoid the position of the clamp 14, and the inclined connecting arm 17 also has a larger adjustment range. The specific adjustment method is to control the rotation and movement of the connecting arm 17 by rotating the transmission head 20 at the end of the connecting arm 17 with a tool, so that the end of the connecting arm 17 is inclined and close to the rotor module 2. The connecting arm 17 is connected to the contact arm 18 and will also press horizontally towards the rotor module 2, so that the rotation force of the rotary table 15 can be smoothly transmitted.

[0035] The docking platform 22 is rotatably connected to the connecting arm 17. When the connecting arm 17 rotates, it can remain relatively stationary and does not rotate. It only pushes the contact arm 18 to be pressed against the rotor core in an inclined direction, ensuring that the power can be transmitted smoothly. The contact arm 18 can be long rod-shaped and can be directly inserted into the counterweight hole on the rotor core. If there is no counterweight hole or other hole that can be inserted, the contact arm 18 can be directly pressed and fixed to the surface of the rotor core. The contact arm 18 always remains in a horizontal state, ensuring the smooth transmission of power after being tilted and pressed down.

[0036] The spherical design of the docking platform 22 allows it to be adapted to different models of contact arms 18. The docking platform 22 itself can also be detached from the connecting arm 17, allowing the connecting arm 17 to be pulled out from the rotary table 15. After all the synchronizing rings 16 are fixed, all docking platforms 22 are locked by the synchronizing rings 16, further ensuring that the force of the rotary table 15 is transmitted to the contact arms 18 and the rotor module 2. The synchronizing rings 16 can be wound steel cables or other lockable components. The binding groove 21 can be opened on the surface or be a perforated design to ensure the locking of the docking platform 22.

[0037] When there are no holes on the surface of the rotor core, a friction head 19 is installed at the end of the contact arm 18. As the contact arm 18 tilts and presses down to press against the surface of the rotor core, the friction layer can provide huge frictional force, ensuring that the rotor module 2 rotates normally under the force transmission. The adsorption component can be a magnetic adsorption component or a negative pressure adsorption component, which further improves the connection force.

[0038] When closing is required, two rollers, one above the other, can be used to squeeze synchronously. After the rotor module 2 moves into position, the separation rail 9 is moved away, allowing the closing roller 10 to move directly below the closing roller 3. The closing roller 10 can also be raised and lowered. During the closing operation, the closing roller 3 and the closing roller 10 squeeze the rotor module 2 synchronously, one above the other. This not only doubles the work efficiency, but also prevents the rotor module 2 from being subjected to excessive downward squeezing force due to the offsetting of the upper and lower forces, thus ensuring the safe processing of the rotor module 2.

[0039] The lifting platform 12 controls the lifting and lowering of the closing roller 10, and the flat platform 11 moves synchronously with the separating rail 9 to ensure the normal process of rail repositioning.

[0040] The bending state of the connecting arm 7 ensures that the rotor module 2 moves smoothly without collision, while the two lifting rails 6 ensure the stable lifting of the connecting arm 7; the detection module 8 can detect the reaction force of the rotor module 2 on the closing roller 3 after the connecting arm 7 is fixed at a certain height, thus realizing the function of finished product detection.
