[0002] Tapered roller bearings are separable bearings. Both the inner and outer rings of the bearings have tapered raceways. This type of bearing can be divided into different structural types such as single-row, double-row and four-row tapered roller bearings according to the number of rows of rollers installed. Tapered roller bearings need to be polished using a polishing device after production.

[0003] When in use, the existing polishing device is difficult to adjust according to the size of the bearing to be processed, and is therefore difficult to apply to bearings of various sizes, which increases the existing device's additional production cost during processing and further reduces the applicability of the existing device.

By setting a device box, a support plate, a limit device, a fixed plate and a rotating device, the cylinder is started, and the cylinder pushes the connecting rod and the rack to move synchronously, so that the rack drives the gear, the first rotating shaft and the rotating disk to rotate synchronously. While the rotating disk makes the three sliders slide relatively in the three slide grooves, the three sliders drive the three dovetail blocks, the moving blocks and the buffer blocks to move relatively in the three limit grooves, so that the device can be adjusted accordingly according to the size of the bearing to be processed, and then can limit bearings of various sizes, avoiding the situation that the device needs to increase a certain amount of additional production cost during processing, and further improving the applicability of the device.
