Description

Technical Field

[0001] The utility model belongs to the technical field of motor rotor processing, and in particular relates to a motor rotor polishing device. Background Art

[0002] The motor rotor is the rotating part of the motor. The motor consists of two parts: the rotor and the stator. It is a device used to realize the conversion of electrical energy into mechanical energy and mechanical energy into electrical energy. The motor rotor is divided into the motor rotor and the generator rotor. Since there are burrs and uneven textures on the surface of the newly produced motor rotor, the air gap between the stator and the rotor is increased, which in turn increases the magnetic resistance, increases the motor no-load current, and the rated current remains unchanged, which reduces the motor output. Therefore, the surface polishing of the motor rotor needs to ensure a consistent polishing thickness and minimize the air gap between the stator and the rotor. Therefore, the motor rotor needs to be finely polished during production;

[0003] After checking, the disclosure (announcement) number: CN211940305U discloses a polishing device for a motor rotor.

When the threaded rod is rotated, the screw sleeve threadedly connected to the threaded rod drives the sliding seat to translate along the slide rail on the fixed plate to adjust the spacing between the fixed seat and the sliding seat.

When the threaded rod is rotated, the screw sleeve threadedly connected to the threaded rod drives the sliding seat to translate along the slide rail on the fixed plate to adjust the spacing between the fixed seat and the sliding seat.

The motor rotor polishing device also includes a clamping assembly 2 installed on the upper surface of the base 1, and the clamping assembly 2 includes a polishing box 21 fixed above the base 1. The polishing box 21 has a groove 22 opened inside, and a placement box 23 is fixedly connected above the groove 22.

[0039] In this embodiment, the relative movement of the rack plate 29 drives the limiting rod 212 to move in the limiting groove 211 to limit the relative movement of the rack plate 29 , and the relative movement of the rack plate 29 is performed in the extension hole 213 .

[0040] Going further:

[0041] In an optional embodiment, the interior of the support frame 210 is rotatably connected to a rotating shaft 214 via a bearing sleeve 215, and one end of the rotating shaft 214 close to the splint 220 is fixedly connected to the splint 220, and one end of one of the rotating shafts 214 away from the splint 220 is fixedly connected to a worm gear 216, and one side of the worm gear 216 is meshingly connected to a worm 217, and one end of the worm 217 is fixedly connected to a first motor 218, and the first motor 218 is fixedly connected to the support frame 210 via a fixing frame 219.

[0042] In this embodiment, the first motor 218 drives the worm 217 to operate, thereby driving the worm wheel 216 to rotate through the worm 217, and then driving the rotating shaft 214 to rotate, thereby driving the clamping plate 220 to flip through the rotation of the rotating shaft 214.

[0043] Going further:

[0044] In order to effectively absorb the iron filings generated during the polishing process and avoid the iron filings from causing harm to the workers, the motor rotor polishing device also includes a cleaning component 3 installed on one side of the polishing box 21. The cleaning component 3 includes a collecting box 31 fixed on the upper surface of the base 1. The interior of the collecting box 31 is fixedly connected to a water tank 32. The interior of the water tank 32 is fixedly connected to a filter screen 33. The interior of the collecting box 31 is fixedly connected to the top of the water tank 32. The interior of the collecting box 31 is fixedly connected to a fan 34 near the top of the water tank 32. The input end of the fan 34 is fixedly connected to a dust suction pipe 35. The end of the dust suction pipe 35 away from the fan 34 passes through the interior of the collecting box 31 and extends to the interior of the polishing box 21 and is connected to the polishing box 21. The two collecting boxes are connected, and the output end of the fan 34 is fixedly connected to a dust exhaust pipe 36, and the end of the dust exhaust pipe 36 away from the fan 34 passes through the upper surface of the filter 33, extends to the lower surface of the filter 33, and is connected to the water tank 32. The interior of the collecting box 31 is fixedly connected to the dust exhaust pipe 36, and one end of the dust exhaust pipe 36 is arranged above the filter 33, and the other end of the dust exhaust pipe 36 passes through the interior of the collecting box 31 and extends to the outside of the collecting box 31. A water inlet pipe 38 is fixed to one side of the water tank 32, and a water outlet pipe 39 is fixed to one side of the water tank 32. The ends of the water inlet pipe 38 and the water outlet pipe 39 away from the water tank 32 both pass through the interior of the collecting box 31 and extend to the outside of the collecting box 31.

[0045] In this embodiment: through the operation of the fan 34, the dust in the polishing box 21 is sucked into the dust suction pipe 35, and then discharged into the water tank 32 from the dust exhaust pipe 36. After the dust falls into the water tank 32, the air in the water tank 32 is filtered out by the filter net 33, and finally the exhaust pipe 37 discharges the air in the water tank 32 to the outside of the collection box 31. The water inlet pipe 38 fills the water tank 32 with water, and the sewage in the water tank 32 is discharged through the water outlet pipe 39, thereby achieving the cleaning of the water tank 32.

[0046] Going further:

[0047] In an optional embodiment, the interior of the polishing box 21 is rotatably connected to a screw rod 4 through a bearing bracket near the top of the splint 220, one end of the screw rod 4 passes through the interior of the polishing box 21, extends to the outside of the polishing box 21, and is fixedly connected to the output end of a second motor 5 arranged on the outside of the polishing box 21, a sliding rod 6 is fixedly connected to the interior of the polishing box 21 near the top of the screw rod 4, a slider 7 is threadedly connected to the outer wall of the screw rod 4, a connecting block 8 is slidably connected to the outer surface of the sliding rod 6, the slider 7 and the connecting block 8 are fixedly connected, the lower surface of the slider 7 is fixedly connected to a mounting plate 9, the lower surface of the mounting plate 9 is fixedly connected to a telescopic rod 10, the end of the telescopic rod 10 away from the mounting plate 9 is fixedly connected to a support plate 11, the lower surface of the support plate 11 is fixedly connected to a third motor 12, and the output end of the third motor 12 is fixedly connected to a polishing wheel 13.

[0048] In this embodiment: the operation of the second motor 5 drives the slider 7 to move on the surface of the screw rod 4, and then drives the connecting block 8 to slide on the surface of the slide rod 6, so as to limit the movement of the slider 7. When the slider 7 moves to the top of the motor rotor, the polishing wheel 13 is driven by the telescopic rod 10 to move downward to contact the motor rotor. When the polishing wheel 13 contacts the motor rotor, the third motor 12 is turned on, and the operation of the third motor 12 drives the polishing wheel 13 to polish the motor rotor.

[0049] The working principle and use process of the utility model are as follows: first, the motor rotor to be clamped is placed between the two clamping plates 220, and then the driving motor 24 is started. The driving motor 24 starts to drive the rotating rod 25 to rotate in the through hole 26, thereby driving the gear 28 to rotate. Since the rack plate 29 is meshed with the gear 28, it is possible to drive the two rack plates 29 to move toward each other or in the opposite direction. The relative movement of the rack plates 29 can drive the support frame 210 to move toward each other in the guide groove 27, so as to realize the relative movement of the clamping plates 220. The movement of the rack plate 29 is controlled by the limit rod 212. The movement in the limiting groove 211 is limited, so that the motor rotor is clamped and fixed by the rubber pad 221. After the motor rotor is clamped and fixed, the operation of the driving motor 24 is stopped, and then the second motor 5 is turned on. The operation of the second motor 5 drives the screw rod 4 to operate in the polishing box 21, thereby driving the slider 7 to move on the surface of the screw rod 4, and sliding on the surface of the slide rod 6 through the connecting block 8, thereby limiting the movement of the slider 7. When the slider 7 moves to the top of the rotor, the polishing wheel 13 and the motor rotor are brought into contact through the telescopic rod 10. At this time, the third motor 12 is turned on, and the third motor 12 is turned on. The operation of the machine 12 drives the polishing wheel 13 to polish the motor rotor. When the polishing wheel 13 finishes polishing one side of the rotor, the first motor 218 is started. The start of the first motor 218 drives the worm 217 to rotate. The worm 217 engages and drives the worm wheel 216 to rotate. Since the worm wheel 216 is fixedly connected to the rotating shaft 214, the rotating shaft 214 can be driven to rotate. Since the rotating shaft 214 and the clamping plate 220 are fixed, the rotation of the rotating shaft 214 can drive the motor rotor fixed between the clamping plate 220 and the rubber pad 221 to turn over synchronously, which increases the convenience of turning over. During this period, as the dust polished by the polishing wheel 13 falls into the polishing box 21, the fan 34 is turned on. As the dust passes through the dust suction pipe 35 at the input end of the fan 34, the dust inside the dust exhaust pipe 36 at the output end of the fan 34 falls into the water tank 32. After the dust falls into the water tank 32, the air in the water tank 32 is filtered out by the filter net 33, and finally the exhaust pipe 37 discharges the air in the water tank 32 to the outside of the collection box 31. In order to clean the water tank 32 more conveniently, the water tank 32 is filled with water through the water inlet pipe 38, and the sewage in the water tank 32 is discharged through the water outlet pipe 39.
