Description

Technical Field

[0001] This invention belongs to the field of burr removal technology, and particularly relates to an automatic burr removal mechanism for stator and rotor cores. Background Technology

[0002] The stator and rotor cores are the core components of motors and generators. The stator core is responsible for forming the magnetic flux circuit of the motor and fixing the stator coils. The rotor core, the stator core, and the air gap between them together form the complete magnetic circuit of the motor. The machining accuracy directly determines the operating efficiency, energy consumption, and service life of the motor. At present, stator and rotor cores are generally produced by stamping and stacking silicon steel sheets. During the stamping, stacking, and cutting process, burrs are easily generated on the inner circle slots, outer circle edges, stacked end faces, and inner walls of the shaft holes of the core.

[0003] A search revealed Chinese Patent Publication No. CN118895507A, which discloses a deburring device for motor stator and rotor laminations, relating to the technical field of deburring equipment. The device includes a fixed box and a connecting plate. A positioning mechanism is installed on the side end of the connecting plate. The positioning mechanism includes a second support rod, a first sleeve plate, and an expansion plate. A telescopic rod is fixedly installed on the side end of the first sleeve plate, and a second sleeve plate is fixedly installed on the top end of the telescopic rod. At least two first card seats are fixedly installed on the surface of the second sleeve plate. The second sleeve plate moves towards the side end of the first sleeve plate, causing multiple first card seats to move synchronously. The first card seats push the end of a push rod, causing the push rod to rotate inside the first card seat. Simultaneously, the top end of the push rod is rotatably connected to the second card seat. The push rod deflects upward, pushing the second card seat upward, causing multiple expansion plates to expand outward synchronously. This device can install different types of motor stator and rotor laminations, increasing its versatility.

[0004] Regarding the aforementioned technologies, the inventors have discovered the following defects: Existing automatic deburring equipment mostly adopts a single brush or grinding wheel structure, which can only remove burrs from a single surface of the iron core. This results in incomplete deburring and many dead corners. In particular, it cannot effectively remove burrs from complex parts such as the inner groove of the stator and the inner wall of the rotor shaft hole, thus affecting the product qualification rate.

[0005] Therefore, the present invention provides an automatic burr removal mechanism for stator and rotor cores to solve the above-mentioned problems. Summary of the Invention

[0017] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. In this invention, by setting up a multi-directional adjustment mechanism and a multi-dimensional grinding mechanism, the adjustment disk is rotated under the action of a rotary motor, thereby achieving deburring of different positions of the stator and rotor core. The deburring mechanism achieves thorough removal of burrs on all surfaces and parts of the core through multi-dimensional collaborative grinding, improving the efficiency and comprehensiveness of burr removal of the stator and rotor core. This allows the deburring mechanism to be adapted to stator and rotor cores of different materials and with different degrees of burrs. At the same time, when deburring the inner hole of the stator and rotor core, the inner ring grinding component can be adjusted according to the size of the inner hole to ensure the deburring effect of the inner hole of the stator and rotor core. Furthermore, the deburring mechanism is applicable to stator and rotor cores with different inner hole sizes, thus improving the applicability of the deburring mechanism.

[0018] 2. In this invention, a collection mechanism is provided. The negative pressure generated by the negative pressure fan draws the burrs and debris generated during the grinding process into the collection hood in a timely manner, preventing the debris from adhering to the surface of the iron core and affecting product quality. At the same time, it prevents the debris from falling into the equipment and extends the service life of the equipment. The filter plate can protect the negative pressure fan and prevent the debris from entering the fan and causing damage. It can also filter the debris in the coolant, realize the recycling of the coolant, and reduce the cost of removing burrs from the stator and rotor iron cores.

[0019] 3. In this invention, a positioning mechanism is provided. As the worm rotates, the worm wheel drives the rotating rod to rotate within the rotating frame, thereby driving the drive gear to rotate synchronously. Under the drive of the drive gear, the transmission gear rotates within the rotating column. At this time, the fixed rack will be displaced within the sliding groove, thereby driving the moving rod to move within the moving groove under the limitation of the limiting strip and the limiting groove. The moving rod drives the clamping rod to retract on the fixed plate, thereby clamping and fixing the stator and rotor cores through the silicone anti-slip pad. This achieves clamping of stator and rotor cores of different diameters. The silicone anti-slip head can buffer the clamping force, avoid damage to the insulation layer on the surface of the core, and reduce the damage caused by the elimination mechanism when fixing the stator and rotor cores. This allows the elimination mechanism to not only achieve adaptive clamping and ensure stable clamping, but also prevent excessive pressure from damaging the core. Attached Figure Description

[0033] In specific implementation, such as Figures 1-11As shown, the present invention provides a technical solution: an automatic burr removal mechanism for stator and rotor cores, comprising a frame 1, with a mounting plate fixedly installed on one half of the upper surface of the frame 1, and the other half configured as a through slot.

[0034] The inner ring grinding assembly 706 includes a fixed disk 7061 and a grinding plate 7068. The side wall of the fixed disk 7061 is provided with several positioning grooves 7062. A fixed post 7063 is fixedly installed on the side wall of the fixed disk 7061. A groove 7064 is provided on the inner surface of the fixed post 7063. The groove 7064 passes through the interior of the fixed post 7063. A threaded rod 7065 is rotatably installed on the inner wall of the bottom surface of the groove 7064. A locking nut and a lifting threaded sleeve 7066 are threadedly installed on the outer surface of the threaded rod 7065. The lifting threaded sleeve 7066 is located inside the groove 7064, and the locking nut is located outside the fixed post 7063.

[0035] A positioning block 7070 is fixedly installed on the lower surface of the grinding plate 7068. The positioning block 7070 is slidably connected to the inner wall of the positioning groove 7062. A fixing block 7069 is fixedly installed on the inner surface of the grinding plate 7068. A connecting block 7067 is fixedly installed on the outer surface of the lifting threaded sleeve 7066. A movable rod 7071 is rotatably installed between the fixing block 7069 and the connecting block 7067 through a rotating shaft. The central axis of the movable rod 7071 is rotatably connected to the inner side wall of the groove 7064 through the rotating shaft. The grinding disc is an arc-shaped plate.

[0036] The multi-directional adjustment mechanism 5 includes a movable frame 501. A guide rail block 505 is fixedly installed on the lower surface of the movable frame 501. A guide rail 503 is symmetrically fixedly installed on the upper surface of the mounting frame 4. The guide rail block 505 is slidably connected to the inner wall of the guide rail 503. A sliding groove 502 is provided on the upper surface of the movable frame 501. A movable adjustment cylinder 506 is fixedly installed on the inner side wall of the sliding groove 502. A sliding plate 507 is fixedly installed at one end of the movable adjustment cylinder 506. One end of the sliding plate 507 extends to the outside of the upper surface of the movable frame 501 and is fixedly connected to the side wall of the fixed frame 701.

[0037] A fixed cylinder 504 is fixedly installed on the inner surface of the mounting bracket 4. A threaded post 509 is rotatably installed on the inner side wall of the fixed cylinder 504. One end of the threaded post 509 extends to the outside of the fixed cylinder 504. A stepper motor 508 is fixedly installed on the upper surface of the mounting bracket 4 through a connecting seat. The output end of the stepper motor 508 is fixedly connected to one end of the threaded post 509. A movable threaded sleeve 5010 is threadedly installed on the outer surface of the threaded post 509. A connecting plate 5011 is symmetrically fixedly installed on the outer surface of the movable threaded sleeve 5010. One end of the connecting plate 5011 is fixedly connected to the inner surface of the movable bracket 501.

[0038] Specifically, by setting up a multi-directional adjustment mechanism 5 and a multi-dimensional grinding mechanism 7, a stepper motor 508 drives a threaded column 509 to rotate within a fixed cylinder 504. Under the action of the thread, a moving threaded sleeve 5010 will be displaced on the outer surface of the threaded column 509. At this time, the moving threaded sleeve 5010 drives the moving frame 501 to move horizontally under the limit of the guide rail 503 and the guide rail block 505 through the connecting plate 5011, thereby driving the multi-dimensional grinding mechanism 7 to move horizontally synchronously. Then, the moving adjustment cylinder 506 causes the slide plate 507 to move laterally within the slide groove 502, thereby driving the multi-dimensional grinding mechanism 7 to move laterally synchronously, thus making the multi-dimensional grinding mechanism 7 fit with the surface of the stator and rotor core. When deburring the outer surface of the stator and rotor core, the rotary motor 702 drives the adjusting plate 703 to rotate, so that the outer ring grinding plate 705 is aligned with the stator and rotor core. Then, under the action of the multi-directional adjusting mechanism 5, the outer ring grinding plate 705 is in contact with the outer surface of the stator and rotor core. Driven by the servo motor 704, the outer ring grinding plate 705 removes the burrs from the outer surface of the stator and rotor core. Then, the rotary motor 702 drives the adjusting plate 703 to rotate, aligning the inner ring grinding assembly 706 with the inner hole of the stator and rotor core. Then, under the action of the multi-directional adjusting mechanism 5, the inner ring grinding assembly 706 penetrates into the inner hole of the stator and rotor core. By rotating the threaded rod 7065, the lifting threaded sleeve 7066 will be displaced on the surface of the threaded rod 7065. At this time, under the action of the connecting block 7067, the movable rod 7071 and the fixed block 7069, the expansion plate will expand on the fixed plate 7061 under the limit of the positioning groove 7062 and the positioning block 7070, so that the outer surface of the grinding plate is in contact with the inner surface of the inner hole of the stator and rotor core. Then, under the drive of another servo motor 704, the inner ring grinding assembly 706 removes the burrs from the inner hole of the stator and rotor. Finally, the rotary motor 702 drives the adjusting plate 703 to rotate, so that the slot grinding needle 707 is aligned with the slot of the stator and rotor iron core. Driven by another servo motor 704, the slot grinding needle 707 rotates at high speed. Then, under the action of the multi-directional adjusting mechanism 5, the slot grinding needle 707 performs deburring treatment on multiple slots in the stator and rotor iron core.

[0039] The collection mechanism 6 includes a collection cover 601, the upper surface of which is fixedly connected to the lower surface of the mounting frame 4. A filter plate 602 is fixedly installed on the inner surface of the collection cover 601. A water pumping pipe 604 is connected to the lower surface of the collection cover 601. An air extraction pipe 603 is connected to the side wall of the collection cover 601. One end of both the air extraction pipe 603 and the water pumping pipe 604 extends to the outside of the frame 1.

[0040] Specifically, by setting up the collection mechanism 6, during the deburring process of the stator and rotor iron core, the negative pressure fan draws the gas out of the collection hood 601 through the exhaust pipe 603. At this time, the collection hood 601 and the area above it are under negative pressure, thereby sucking the grinding debris into the collection hood 601. The debris will be filtered down by the filter plate 602. At the same time, the coolant during the deburring process will also fall into the collection hood 601. The debris in the coolant will be filtered by the filter plate 602. The filtered coolant will be pumped away by the water pump through the water pipe 604. When the debris on the filter plate 602 reaches a certain amount, the debris will be cleaned.

The driven pulley 206 and the drive pulley 203 are connected by belt drive.

[0042] The positioning mechanism 3 includes a rotating frame 301. The side wall of the rotating frame 301 is fixedly connected to the other end of the rotating column 205. A rotating rod 302 is rotatably mounted on the inner side wall of the rotating frame 301. A worm gear 303 and a drive gear 307 are fixedly mounted on the outer surface of the rotating rod 302. A worm 304 is rotatably mounted on the inner wall of the cavity of the rotating frame 301. The worm 304 and the worm gear 303 mesh with each other. The other end of the worm 304 extends to the outside of the rotating frame 301. Several sliding grooves 305 are equidistantly arranged on the other side wall of the rotating frame 301.

[0043] The outer surface of the rotating frame 301 is provided with several positioning holes 3015. The positioning holes 3015 surround the worm gear 304. The upper surface of the worm gear 304 is provided with a mounting groove 3016. A connecting spring 3019 is fixedly installed on the inner wall of the bottom surface of the mounting groove 3016. A limit block 3018 is fixedly installed on one end of the connecting spring 3019. One end of the limit block 3018 extends to the outside of the mounting groove 3016 and is fixedly installed with a knob 3017. Positioning pins 3020 are symmetrically fixedly installed on the lower surface of the knob 3017. The positioning pins 3020 and the positioning holes 3015 are mutually adapted to each other.

[0044] A plurality of transmission gears 306 are rotatably mounted at equal intervals on the inner side wall of the rotating frame 301. The transmission gears 306 mesh with the drive gear disk 307. A fixed cover 308 is fixedly mounted on the other side wall of the rotating frame 301. A plurality of moving grooves 3013 corresponding to the sliding grooves 305 are provided on the side wall of the fixed cover 308. Limiting grooves 3014 are provided on both sides of the moving grooves 3013. Moving rods 3010 are slidably mounted on the inner wall of the limiting grooves 3014. Limiting strips 3011 are fixedly mounted on both sides of the moving rods 3010. The limiting strips 3011 and the limiting grooves 3014 are mutually adapted. A fixed rack 3012 is fixedly mounted on the side wall of the moving rod 3010. The fixed rack 3012 meshes with the transmission gears 306. A clamping rod 309 is fixedly mounted on the other side wall of the moving rod 3010. A silicone anti-slip head is fixedly mounted on one end of the clamping rod 309.

[0045] Specifically, by setting up the drive mechanism 2 and the positioning mechanism 3, one end of the stator and rotor cores is attached to the side wall of the fixed cover 308. Then, the knob 3017 is pulled up to disengage the positioning pin 3020 from the positioning hole 3015. Then, the knob 3017 is rotated. At this time, the knob 3017 drives the worm 304 to rotate within the rotating frame 301 through the limit block 3018 and the connecting spring 3019. As the worm 304 rotates, the worm wheel 303 drives the rotating rod 302 to rotate within the rotating frame 301. The drive gear 307 rotates synchronously, and the transmission gear 306 rotates in the rotating column 205 under the drive of the drive gear 307. At this time, the fixed rack 3012 will be displaced in the sliding groove 305, thereby driving the moving rod 3010 to move in the moving groove 3013 under the limit of the limit bar 3011 and the limit groove 3014. The moving rod 3010 drives the clamping rod 309 to retract on the fixed plate 7061, thereby clamping and fixing the stator and rotor cores through the silicone anti-slip pad. After the stator and rotor cores are fixed, during the deburring process, the drive motor 202 drives the drive pulley 203 to rotate. Under the transmission of the belt, the driven pulley 206 drives the rotating column 205 to rotate inside the support platform 204. At this time, the rotating column 205 drives the positioning mechanism 3 to rotate synchronously, thereby driving the stator and rotor cores to rotate and deburr.

[0046] Working principle: Install the frame 1 on a stable ground, and then adjust the positioning mechanism 3 according to the size of the stator and rotor cores. After the size of the positioning mechanism 3 is adjusted, install the stator and rotor cores that need to be deburred in the positioning mechanism 3. Then connect the air extraction pipe 603 in the collection mechanism 6 to the air extraction end of the negative pressure fan, and connect the water extraction pipe 604 to the water extraction end of the water pump. After the stator and rotor cores are positioned and installed, the multi-dimensional grinding mechanism 7 will perform deburring treatment on the stator and rotor cores in the order of grinding the outer ring, inner ring and slot. Depending on the grinding position, the multi-directional adjustment mechanism 5 will drive the multi-dimensional grinding mechanism 7 to make real-time adjustments to ensure the fit between the multi-dimensional grinding mechanism 7 and the stator and rotor cores. During the grinding process, the drive mechanism 2 will drive the positioning mechanism 3 to rotate, thereby driving the stator and rotor cores to rotate during the grinding process to ensure the completion of the deburring of the stator and rotor cores. The debris and coolant generated during the deburring of the stator and rotor cores will be recycled by the collection mechanism 6.
