[0022] Example 1: Figures 1 to 11 As shown, a bearing inner ring grinding device described in an embodiment of the present invention includes a base plate 1, the upper surface of the base plate 1 is fixedly connected to a first support frame 11, the interior of the first support frame 11 is fixedly connected to a discharge frame 12, the upper surface of the base plate 1 is rotatably connected to a first turntable 4, the interior of the first turntable 4 is rotatably connected to a second turntable 5, the interior of the second turntable 5 is slidably connected to a clamping plate 53, and the clamping plate 53 includes a transverse end 531. A grinding mechanism 2 is provided on the upper surface of the base plate 1, and the grinding mechanism 2 includes an outer shell 22, the interior of the outer shell 22 is rotatably connected to a rotating plate 23, the lower surface of the rotating plate 23 is fixedly connected to a shift rod 231, the lower surface of the outer shell 22 is rotatably connected to a grinding roller 26, the rotation directions of the grinding roller 26 and the rotating plate 23 are opposite, and the interior of the base plate 1 is fixedly connected to a discharge port 14.

[0023] Specifically, when using the existing bearing inner ring grinding device, the bearing is generally fixed by a clamp, and then the inner wall of the bearing is ground using a grinding roller 26. Since the bearing is fixed, when the grinding roller 26 stays in the area for a long time, it will cause the bearing to be locally over-ground or under-ground.

[0024] In order to avoid the above technical problems, the present device is used as follows: when using the device, the bearing body 6 in the unloading rack 12 falls into the second turntable 5 inside the first turntable 4, and then the first turntable 4 is driven to rotate intermittently, and the first turntable 4 drives the bearing body 6 inside the second turntable 5 to rotate synchronously. When the bearing body 6 rotates to the grinding mechanism 2, the clamping plate 53 inside the second turntable 5 is driven to slide toward the outer wall of the bearing body 6, and the clamping plate 53 contacts the outer wall of the bearing body 6 and clamps the outer wall of the bearing body 6. At the same time, the horizontal end 531 of the clamping plate 53 is on the upper surface of the bearing body 6, and then the grinding roller 26 and the turntable 23 are driven. The grinding roller 26 and the rotating plate 23 rotate in opposite directions, and the rotating plate 23 drives the lever 231 to rotate synchronously. The grinding roller 26 and the rotating plate 23 descend synchronously, and the inner ring of the bearing of the grinding roller 26 contacts, and the lever 231 contacts the upper surface of the inner ring of the bearing. When the grinding roller 26 performs a grinding operation on the inner ring of the bearing, the lever 231 rotates and contacts the transverse end 531 and drives the transverse end 531 to rotate synchronously. The transverse end 531 drives the clamping plate 53 and the second turntable 5 to rotate synchronously. The clamping plate 53 drives the bearing body 6 to rotate synchronously, and the rotation direction is opposite to that of the grinding roller 26. The grinding roller 26 can perform all-round grinding on the inner wall of the bearing body 6. After the grinding is completed, the first turntable 4 is driven to drive the bearing body 6 to rotate to the discharge port 14 , and the bearing body 6 is discharged through the discharge port 14 .

[0025] This device fixes the bearing body 6 through the clamping plate 53, and drives the bearing body 6 to rotate in the opposite direction through the clamping plate 53, so that the grinding roller 26 contacts the inner wall of the bearing more fully, avoiding local over-grinding or under-grinding caused by unidirectional rotation, and improving the grinding effect.

[0027] Specifically, when it is necessary to drive the first turntable 4 to rotate intermittently, turn on the servo motor 16, and the servo motor 16 drives the rotating end of the first turntable 4 to rotate ninety degrees, thereby completing a series of operations of automatic loading, grinding and unloading. After grinding, the bearing body 6 moves to the discharge port 14, falls onto the discharge rack 15 through the discharge port 14, and is discharged through the discharge rack 15.

[0029] Specifically, when it is necessary to drive the grinding roller 26 and the shift rod 231 to descend, the electric cylinder can be opened, and the telescopic rod of the electric cylinder passes through the rotating ends of the first bevel gear 232 and the third bevel gear 25, and is fixed to the inner lower surface of the outer shell 22. Therefore, the output end of the electric cylinder drives the outer shell 22 to descend, and the outer shell 22 drives the shift rod 231 and the grinding roller 26 to descend.

[0031] Specifically, when it is necessary to drive the grinding roller 26 and the rotating plate 23 to rotate in opposite directions, the grinding motor 24 can be turned on, and the grinding motor 24 drives the second bevel gear 241 to rotate, and the second bevel gear 241 is respectively engaged with the first bevel gear 232 and the third bevel gear 25, so that the first bevel gear 232 drives the rotating plate 23 to rotate, and the rotating plate 23 drives the shift lever 231 to rotate. At the same time, the third bevel gear 25 drives the pulley 251 on its rotating end to rotate synchronously, and the pulley 251 drives the pulley 251 on the rotating end of the grinding roller 26 to rotate synchronously through the belt, so that the grinding roller 26 rotates.

[0033] Specifically, when it is necessary to drive the splint 53 to move, the second turntable 5 drives the magnetic block 51 to move to the bottom of the electromagnetic plate, and the electromagnet 31 is energized, so that the electromagnet 31 generates a repulsive force on the magnetic block 51, and the magnetic block 51 slides toward the inside of the second turntable 5, and the magnetic block 51 squeezes the second elastic telescopic rod 511 and drives the squeezing block 512 to descend, and the squeezing block 512 drives the moving rod 52 to move toward the outer wall of the bearing, and the moving rod 52 drives the splint 53 to slide synchronously, and the splint 53 drives the roller 533 to slide inside the limit frame 54, and the splint 53 contacts and clamps the outer wall of the bearing body 6, and at the same time, the splint 53 drives the lateral end 531 to contact the upper surface of the bearing body 6, and the bearing body 6 can be fixed.

[0035] Specifically, when the inner ring of the bearing is being ground, a small amount of extremely small debris will remain on the stainless steel inner ring of the bearing during grinding. The grinding roller 26 and the debris will come into contact again, causing grinding scratches.

[0036] When the lever 231 drives the clamping plate 53 to rotate, the clamping plate 53 drives the squeezing rod 532 to rotate, and the squeezing rod 532 rotates to the protrusion 32, and the protrusion 32 squeezes the squeezing rod 532, and the squeezing rod 532 drives the clamping plate 53 to move downward, and the clamping plate 53 drives the bearing body 6 to move downward through the horizontal end 531, and the bearing body 6 drives the movable plate 17 to move downward, and the movable plate 17 squeezes the elastic second elastic telescopic rod 511. When the squeezing rod 532 is away from the protrusion 32, the second elastic telescopic rod 511 drives the movable plate 17 to return to its original position, and the above operation is repeated to perform reciprocating vibration on the bearing body 6, and the inner wall debris of the bearing body 6 is shaken off to the filter screen and falls into the filter tube 171. At the same time, an external negative pressure device can be connected to one end of the discharge valve. The negative pressure device generates negative pressure, which can increase the cleaning of the debris on the inner wall of the bearing.

[0037] This device can shake off the grinding debris attached to the inner wall of the pipe, avoiding the problem of the debris contacting the grinding roller 26 and causing scratches on the inner wall. It can also prevent the debris from spreading and reduce the problem of secondary pollution.

[0038] Working principle: When using this device, the bearing body 6 in the unloading rack 12 falls into the second turntable 5 inside the first turntable 4, and the servo motor 16 is turned on. The servo motor 16 drives the rotating end of the first turntable 4 to rotate ninety degrees, and the first turntable 4 drives the bearing body 6 inside the second turntable 5 to rotate synchronously. When the bearing body 6 rotates to the grinding mechanism 2, the electromagnet 31 is energized, so that the electromagnet 31 generates a repulsive force on the magnetic block 51, and the magnetic block 51 slides toward the inside of the second turntable 5, and the magnetic block 51 squeezes the second elastic telescopic rod 51. 1 and drives the extrusion block 512 to descend, the extrusion block 512 drives the moving rod 52 to move toward the outer wall of the bearing, the moving rod 52 drives the clamping plate 53 to slide synchronously, the clamping plate 53 drives the roller 533 to slide inside the limiting frame 54, the clamping plate 53 contacts and clamps the outer wall of the bearing body 6, and at the same time the clamping plate 53 drives the horizontal end 531 to contact the upper surface of the bearing body 6, turning on the grinding motor 24, the grinding motor 24 drives the second bevel gear 241 to rotate, and the second bevel gear 241 is respectively connected to the first bevel gear 232 and the third bevel gear 233.
