Clamp and fix the inner ring of the bearing to be processed through the clamping assembly, place the inner ring of the bearing inside the through groove, and the ring body is between the two sets of clamping plates, start the first motor, and the first motor causes the positive and negative screws to rotate forward or reverse, thereby moving the two sets of moving plates closer to or away from each other, and then the two sets of clamping plates move closer to or away from each other. The spacing between the two sets of clamping plates can be adjusted and controlled according to the diameter of the inner ring of the bearing, and the two sets of clamping plates are used to clamp and fix the two sides of the outer wall of the ring body, turn off the working mode of the first motor, and fix one set of bearing inner ring on each set of clamping assemblies; then the user can turn on the working mode of the first hydraulic cylinder and the second hydraulic cylinder, and the telescopic movement of the first hydraulic cylinder will drive the moving block to extend or retract, and the sliding ring body will slide along the outer circumference of the main long rod at this time. The telescopic movement of the moving block will drive the second hydraulic cylinder, the polishing drive box component and the polishing disc to perform horizontal telescopic movement, and move the polishing disc horizontally to the upper position of the corresponding clamping assembly. When the polishing wheel is in the working state, the second hydraulic cylinder is extended, and the second hydraulic cylinder drives the polishing drive box component and the polishing disc to descend. The polishing disc descends to one side of the bearing ring body on the corresponding clamping assembly, and the polishing disc is in contact with the inner wall of the bearing ring body. At this time, the polishing drive box component working mode can be turned on to drive the polishing disc to polish. The polishing disc polishes the inner wall of the bearing ring body. When the polishing work of the ring body is completed, the polishing drive box component working mode is turned off, the second hydraulic cylinder is retracted, and the polishing disc is retracted to the top of the supporting frame plate assembly at the same time. The polishing disc is away from the workpiece, and the first hydraulic cylinder is started again.

[0017] 2. During the operation of the polishing equipment, it is particularly easy to generate debris and dust, which will also affect the surrounding environment and have a certain impact on the health of the operator; the working mode of this practical dust removal component can be turned on, and the user can turn on the working mode of the dust collection head component and the air pump. The dust collection head component will suck in the debris and dust flying around the clamping component and the workpiece, and the debris and dust will be sucked in from the dust collection head component through the air pump. The debris and dust will then enter the collection chamber and be filtered through the filter plate in the collection chamber. The dust and impurities remain on the surface of the filter plate, and the filtered air is discharged from the through pipe. This operation is beneficial to reduce the debris and dust generated during the polishing of the inner ring of the bearing. The filter plate needs to be cleaned and maintained for a long time after long-term use.

[0034] To sum up, the working principle is as follows: the inner ring of the bearing to be processed is clamped and fixed by the clamping assembly 2, the inner ring of the bearing is placed inside the through groove 22, and the ring body is between the two sets of clamping plates 24, the first motor 23 is started, and the first motor 23 makes the positive and negative screw rods 27 rotate forward or reverse, and then the two sets of moving plates 25 move closer to or away from each other, and then the two sets of clamping plates 24 move closer to or away from each other. The distance between the two sets of clamping plates 24 can be adjusted and controlled according to the diameter of the inner ring of the bearing, and the two sets of clamping plates 24 are used to adjust the distance between the two sets of clamping plates 24. The two sides of the outer wall of the ring body are clamped and fixed, and the working mode of the first motor 23 is turned off. A group of bearing inner rings are fixed on each clamping assembly 2; then the user can turn on the working mode of the first hydraulic cylinder 14 and the second hydraulic cylinder 17. The telescopic movement of the first hydraulic cylinder 14 will drive the moving block 16 to extend or retract. At this time, the sliding ring body 15 slides along the outer periphery of the main long rod 13. The telescopic movement of the moving block 16 will drive the second hydraulic cylinder 17, the polishing drive box component 11 and the polishing disc 12 to perform horizontal telescopic movement, and the polishing disc 12 will be moved horizontally to the opposite side. When the polishing work on the ring body is completed, the polishing drive box component 11 working mode is turned off, the second hydraulic cylinder 17 is retracted, and the polishing disc 12 is retracted to the top of the supporting frame plate component 1, and the polishing disc 12 is away from the workpiece. The first hydraulic cylinder 14 is started again, and the polishing disc 12 is driven to the top of the designated workpiece for processing by the first hydraulic cylinder 14. Then, each group of bearing workpieces is polished in the same way as the above steps. This arrangement enables the device to polish multiple bearing inner rings at the same time, thereby achieving the purpose of batch processing of bearings. The ring body can be stabilized by using the clamp, which improves the convenience of workers' operation, thereby improving the polishing efficiency of the polishing device for the bearing inner ring and improving the practicality of the device.

[0035] During the operation of the polishing equipment, it is particularly easy to generate debris and dust, which will also affect the surrounding environment and have a certain impact on the health of the operator; the working mode of the practical dust removal component 3 can be turned on, and the user can turn on the working mode of the dust collection head component 36 and the air pump 34. The dust collection head component 36 will suck in the debris and dust flying around the clamping component 2 and the workpiece, and the debris and dust will be sucked in from the dust collection head component 36 through the air pump 34, and then the debris and dust will enter the collection chamber 31 and be filtered through the filter plate 32 in the collection chamber 31. The dust and impurities remain on the surface of the filter plate 32, and the filtered air is discharged from the through pipe 33. This operation is beneficial to reduce the debris and dust generated during the polishing of the inner ring of the bearing. If the filter plate 32 is used for a long time, it is necessary to clean and maintain the debris and impurities on it. At this time, the automatic telescopic rod 37 is started to make it retract, thereby driving the card block 38 to retract and remove it from the card slot block 32 After the cleaning is completed, the filter screen panel 32 is slid back into the installation slot of the collection chamber 31 and the filter screen panel 32 is completely slid into the collection chamber 31. At this time, the position of the slot block 321 provided on the rear side of the filter screen panel 32 corresponds to the position of the slot block 38, so that the automatic telescopic rod 37 is extended and the automatic telescopic rod 37 pushes the block 38 to completely enter the slot block 321 until the block 38 is locked and fixedly connected with the slot block 321, that is, the filter screen panel 32 is re-fixed into the collection chamber 31. This arrangement collects the debris generated by the polishing equipment during operation through the dust removal component 3, effectively realizes active dust removal, improves the cleanliness of the surrounding environment, avoids affecting the health of personnel, and improves the practicality of the device.
