Description

Technical Field

[0001] This invention relates to the field of motor stator technology, specifically to a special tooling device for adaptive motor stator winding. Background Technology

[0002] The stator is the stationary core component of a motor, located inside the motor housing and outside the rotor. It does not rotate with the shaft and mainly consists of the stator core, stator windings, and insulation structure. The stator core is made of multiple layers of laminated silicon steel sheets with uniformly spaced slots, serving to conduct magnetism and reduce eddy current losses. The stator windings, the coils of wire embedded in the core slots, are crucial for the stator's function. The reason for winding the stator is to generate a rotating magnetic field through the energized windings, thus converting electrical energy into mechanical energy. A pure silicon steel core itself does not generate a magnetic field; the wires are wound into coils... An electromagnetic field is formed only when electricity is applied. Multiple coils arranged in a regular pattern can generate a continuously rotating magnetic field, which cuts the rotor conductor and induces current, thereby generating electromagnetic torque to drive the rotor to rotate. Multiple turns of coil can superimpose magnetomotive force, obtaining a sufficiently strong magnetic field with a smaller current, thus increasing the motor output. At the same time, different winding methods can be used to set the number of pole pairs of the motor, control the speed and magnetic field waveform, and reduce vibration, noise, and harmonic losses. Adjusting the number of turns and wire diameter can also adapt to different voltage and current levels, determining the rated power specifications of the motor. Therefore, a special tooling equipment for adaptive motor stator winding is needed.

[0003] When operators are winding motor stators, they often use corresponding adaptive motor stator winding special tooling equipment. Although the existing equipment can achieve the purpose of winding, in actual use, the stator is often positioned by rigid clamping, which may cause stator deformation, enameled wire scratches and other problems. Moreover, it cannot automatically adjust the stator stacking thickness, and the stacking thickness needs to be achieved by manually replacing the limit pads and manually adjusting the stops, which may reduce the winding efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a special tooling device for adaptive motor stator winding, in order to solve the problem mentioned in the background art. When operators are winding motor stators, they often use corresponding special tooling devices for adaptive motor stator winding. Although existing devices can achieve the purpose of winding, in actual use, they mostly use rigid clamping to position the stator, which may cause problems such as stator deformation and scratching of enameled wire. Moreover, they cannot automatically adjust the stator stacking thickness, and require manual replacement of limit pads and manual adjustment of stops to achieve the stacking thickness, which may reduce the winding efficiency.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a special tooling device for stator winding of an adaptive motor, comprising a rotating plate, a lifting plate, and a base plate. A placement plate is fixedly installed on the top of the rotating plate. Clamping plates located on the back of the placement plate are fixedly installed on both sides of the top of the rotating plate. A bidirectional threaded rod is rotatably installed between the clamping plates. Sliding sleeves are threaded onto both sides of the surface of the bidirectional threaded rod. A positioning motor is fixedly installed on one side of the clamping plate. The output end of the positioning motor passes through the clamping plate and is fixedly connected to one side of the bidirectional threaded rod. Fixed plates located in front of the placement plate are fixedly installed on both sides of the top of the rotating plate. A round rod is fixedly installed between the fixed plates. Movable blocks are movably sleeved onto both sides of the surface of the round rod. The top of both the movable block and the sliding sleeve is fixedly equipped with a movable plate. A pressure rod is movably installed at equal distances on one side of each movable plate. One side of the pressure rod passes through the movable plate and extends to the other side of the movable plate. A positioning plate is fixedly installed on one side of each pressure rod. A spring is fixedly installed at equal distances between the positioning plate and the movable plate. The inner surface of the spring is movably connected to the outer surface of the pressure rod. A flexible positioning pad is fixedly installed on one side of each positioning plate, and a circular plate is fixedly installed on the other side of each pressure rod.

[0006] Preferably, a turntable is rotatably mounted on the top of the lifting plate, the top of the turntable is fixedly connected to the bottom of the lifting plate, and a rotary motor is fixedly mounted on the bottom of the lifting plate, with the output end of the rotary motor passing through the lifting plate and fixedly connected to the bottom of the turntable.

[0007] Preferably, the base plate has a strip groove inside, and a bidirectional lead screw is rotatably installed inside the strip groove. Adjusting sleeves are threaded onto both sides of the surface of the bidirectional lead screw, and a crossbar is fixedly installed on the top of each adjusting sleeve. The crossbar is located on the top of the base plate, and the outer surface of the crossbar is movably connected to the outer surface of the base plate. An adjusting rod is hinged between the crossbar and the lifting plate.

[0008] Preferably, a lifting motor is fixedly installed on one side of the base plate, and the output end of the lifting motor passes through the base plate and is fixedly connected to one side of the bidirectional lead screw.

[0009] Preferably, vertical tubes are fixedly installed on both sides of the top of the base plate, and vertical plates are movably installed inside each vertical tube. The top of each vertical plate is fixedly connected to the bottom of the lifting plate. A sliding groove is opened on one side of each vertical tube, and a slider is movably installed inside each sliding groove. One side of the slider is fixedly connected to one side of the vertical plate.

[0010] Preferably, anti-slip support plates are fixedly installed on both sides of the bottom of the base plate, and the anti-slip support plates are of the same size.

[0011] Compared with the prior art, the beneficial effects of the present invention are: This invention relates to a specialized tooling device for winding adaptive motor stators. During daily use, the operator places the motor stator between the top of the placement plate and the flexible positioning pad. The positioning motor is then started, causing the bidirectional threaded rod to rotate. This rotation drives two sliding sleeves to slide between the clamping plates and on the surface of the threaded rod. The sliding sleeves then drive the moving plate to slide, which in turn drives the movable block to slide. The movable block then slides between the fixed plates and on the surface of the round rod. When the flexible positioning pad reaches the surface of the motor stator, the stator presses against it, causing it to slide. This, in turn, causes the positioning plate to slide. The positioning plate then drives the pressure rod to slide inside the moving plate. Simultaneously, the positioning plate compresses the spring, putting it in a compressed state. The pressure rod then drives the round plate to slide. This invention automatically positions the motor using the bidirectional threaded rod, positioning motor, and moving plate, and flexibly positions the motor stator using the pressure rod, spring, and flexible positioning pad, thereby reducing problems such as stator deformation and wire scratches caused by rigid positioning.

[0012] This adaptive motor stator winding special tooling equipment, during daily use, involves the operator starting the lifting motor. The operation of the lifting motor causes the bidirectional lead screw to rotate, which in turn drives the adjusting sleeve to slide. Subsequently, the adjusting sleeve slides inside the strip groove and on the surface of the bidirectional lead screw. At this time, the adjusting sleeve drives the crossbar to slide, which then slides on the top of the base plate. The crossbar then drives the adjusting rod to slide, which in turn drives the lifting plate to slide. Simultaneously, the lifting plate drives the vertical plate to slide, which then slides inside the vertical tube. The vertical plate then drives the slider to slide, which in turn slides inside the slide groove. This operation method automatically adjusts the stator stacking height through the lifting motor, adjusting rod, and lifting plate, eliminating the need for manual replacement of limit pads or manual adjustment of stops to achieve stacking thickness.

[0015] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0016] Example 1:

[0017] Please see Figures 1-5 A special tooling device for stator winding of an adaptive motor includes a rotating plate 1, a lifting plate 16, and a base plate 19. A placement plate 2 is fixedly installed on the top of the rotating plate 1. Clamping plates 3 located on the back of the placement plate 2 are fixedly installed on both sides of the top of the rotating plate 1. A bidirectional threaded rod 4 is rotatably installed between the clamping plates 3. Sliding sleeves 5 are threadedly sleeved on both sides of the surface of the bidirectional threaded rod 4. A positioning motor 6 is fixedly installed on one side of the clamping plate 3. The output end of the positioning motor 6 passes through the clamping plate 3 and is fixedly connected to one side of the bidirectional threaded rod 4. Fixed plates 7 located in front of the placement plate 2 are fixedly installed on both sides of the top of the rotating plate 1. A round rod 8 is fixedly installed between the fixed plates 7. Movable blocks 9 are movably sleeved on both sides of the surface of the round rod 8. A movable plate 10 is fixedly installed on the top of both the movable block 9 and the sliding sleeve 5. A pressure rod 11 is movably installed at equal distances on one side of the movable plate 10. One side of the pressure rod 11 passes through the movable plate 10 and extends to the other side of the movable plate 10. A positioning plate 12 is fixedly installed on one side of the pressure rod 11. A spring 13 is fixedly installed at equal distances between the positioning plate 12 and the movable plate 10. The inner surface of the spring 13 is movably connected to the outer surface of the pressure rod 11. A flexible positioning pad 14 is fixedly installed on one side of the positioning plate 12. A circular plate 15 is fixedly installed on the other side of the pressure rod 11. A turntable 17 is rotatably installed on the top of the lifting plate 16. The top of the turntable 17 is fixedly connected to the bottom of the rotating plate 1. A rotary motor 18 is fixedly installed on the bottom of the lifting plate 16. The output end of the rotary motor 18 passes through the lifting plate 16 and is fixedly connected to the bottom of the turntable 17.

[0018] In this invention, the operator can place the motor stator between the top of the placement plate 2 and the flexible positioning pad 14, and then start the positioning motor 6. The operation of the positioning motor 6 will cause the bidirectional threaded rod 4 to rotate. Subsequently, the bidirectional threaded rod 4 will drive the two sliding sleeves 5 to slide between the clamping plates 3 and on the surface of the bidirectional threaded rod 4. At this time, the sliding sleeves 5 will drive the moving plate 10 to slide. Subsequently, the moving plate 10 will drive the movable block 9 to slide. Subsequently, the movable block 9 will slide between the fixed plates 7 and on the surface of the round rod 8. When the flexible positioning pad 14 reaches the surface of the motor stator, the motor stator will squeeze the flexible positioning pad 14 and drive it to slide. Subsequently, the flexible positioning pad 14 will drive the positioning plate 12 to slide. Subsequently, the positioning plate 12 will drive the pressure rod 11 to slide inside the moving plate 10. At the same time, the positioning plate 12 will squeeze the spring 13 and put it in a compressed state. Subsequently, the pressure rod 11 will drive the round plate 15 to slide, thus flexibly positioning the motor stator.

[0019] The wire can be fixed to the surface of the motor stator and the rotary motor 18 can be started. The operation of the rotary motor 18 will cause the turntable 17 to rotate, which in turn will drive the rotating plate 1 to rotate. Subsequently, the rotating plate 1 will drive the placement plate 2 to rotate, which will drive the motor stator on top to rotate, thus enabling the winding work.

[0020] Example 2:

[0021] Please see Figures 1-5 A special tooling device for stator winding of an adaptive motor is provided. A strip groove 20 is opened inside the base plate 19. A bidirectional lead screw 21 is rotatably installed inside the strip groove 20. Adjusting sleeves 22 are threaded on both sides of the surface of the bidirectional lead screw 21. A crossbar 23 is fixedly installed on the top of the adjusting sleeves 22. The crossbar 23 is located on the top of the base plate 19. The outer surface of the crossbar 23 is movably connected to the outer surface of the base plate 19. Adjusting rods 24 are hinged between the crossbar 23 and the lifting plate 16. A lifting motor 25 is fixedly installed on one side of the base plate 19. The output end of the lifting motor 25 passes through the base plate 19 and is fixedly connected to one side of the bidirectional lead screw 21.

[0022] In this invention, the operator starts the lifting motor 25, which causes the bidirectional lead screw 21 to rotate. The bidirectional lead screw 21 then drives the adjusting sleeve 22 to slide. Subsequently, the adjusting sleeve 22 slides inside the strip groove 20 and on the surface of the bidirectional lead screw 21. At this time, the adjusting sleeve 22 drives the crossbar 23 to slide, and the crossbar 23 slides on the top of the base plate 19. Then, the crossbar 23 drives the adjusting rod 24 to slide, and the adjusting rod 24 drives the lifting plate 16 to slide. This allows for automatic adjustment of the stator stacking height without the need for manual replacement of limit pads or manual adjustment of stops.

[0023] Example 3:

[0024] Please see Figures 1-5 A special tooling device for adaptive motor stator winding, wherein vertical tubes 26 are fixedly installed on both sides of the top of the base plate 19, and vertical plates 27 are movably installed inside the vertical tubes 26. The top of the vertical plates 27 is fixedly connected to the bottom of the lifting plate 16. A sliding groove 28 is opened on one side of each vertical tube 26, and a slider 29 is movably installed inside the sliding groove 28. One side of the slider 29 is fixedly connected to one side of the vertical plate 27. Anti-slip support plates 30 are fixedly installed on both sides of the bottom of the base plate 19, and the anti-slip support plates 30 are the same size.

[0025] In this invention, when the lifting plate 16 slides, it will cause the vertical plate 27 to slide. Subsequently, the vertical plate 27 will slide inside the vertical tube 26. The inner surface of the vertical tube 26 and the outer surface of the vertical plate 27 are both smooth, which allows the vertical plate 27 to slide more smoothly inside the vertical tube 26 and reduces the occurrence of jamming. Due to the design of the vertical tube 26 and the vertical plate 27, the sliding of the lifting plate 16 is more stable. Then, the vertical plate 27 will cause the slider 29 to slide. Subsequently, the slider 29 will slide inside the slide groove 28. Due to the design of the anti-slip support plate 30, the base plate 19 is more stable.

[0026] Working principle: The operator can place the motor stator between the top of the placement plate 2 and the flexible positioning pad 14, and then start the positioning motor 6. The operation of the positioning motor 6 will cause the bidirectional threaded rod 4 to rotate. Subsequently, the bidirectional threaded rod 4 will drive the two sliding sleeves 5 to slide between the clamping plates 3 and on the surface of the bidirectional threaded rod 4. At this time, the sliding sleeves 5 will drive the moving plate 10 to slide, and the moving plate 10 will drive the movable block 9 to slide. Subsequently, the movable block 9 will slide between the fixed plates 7 and on the surface of the round rod 8. When the flexible positioning pad 14 reaches the surface of the motor stator, the motor stator will squeeze the flexible positioning pad 14 and drive it to slide. Subsequently, the flexible positioning pad 14 will drive the positioning plate 12 to slide, and then the positioning plate 12 will drive the pressure rod 11 to slide inside the moving plate 10. At the same time, the positioning plate 12 will squeeze the spring 13 and put it in a compressed state. Subsequently, the pressure rod 11 will drive the round plate 15 to slide, thus flexibly positioning the motor stator. Next, the wire is fixed to the surface of the motor stator and the rotating motor 1 is started. 8. The operation of the rotary motor 18 causes the turntable 17 to rotate, which in turn drives the rotating plate 1 to rotate. The rotating plate 1 then drives the storage plate 2 to rotate, which in turn drives the stator of the motor at the top to rotate, thus enabling the winding operation. Finally, the lifting motor 25 is started, and the operation of the lifting motor 25 causes the bidirectional lead screw 21 to rotate. The bidirectional lead screw 21 then drives the adjusting sleeve 22 to slide. The adjusting sleeve 22 then slides inside the strip groove 20 and on the surface of the bidirectional lead screw 21. At this time, the adjusting sleeve 22 drives the crossbar 23 to slide, which then slides on the top of the base plate 19. The crossbar 23 then drives the adjusting rod 24 to slide, which in turn drives the lifting plate 16 to slide. Simultaneously, the lifting plate 16 drives the vertical plate 27 to slide, which then slides inside the vertical tube 26. The vertical plate 27 then drives the slider 29 to slide, which then slides inside the slide groove 28, thus automatically adjusting the stator stacking height.
