s4, then the two moving blocks (802) are pressed and move, the first hinged connecting rod (804) can be driven to slide on the side wall of the supporting rod (7) along with the movement of the moving blocks (802), so that the distance between the first end of the first connecting rod (804) and the second end of the second connecting rod (806) opposite to each other is changed, the arc-shaped polishing plate (807) hinged to one end, opposite to the first connecting rod (804) and the second connecting rod (806), can be adjusted, the distance between the arc-shaped polishing plate (807) and the supporting rod (7) is controlled, the inner diameters of different bearings are polished, when the arc-shaped polishing plate (807) is adjusted to a proper position, the moving blocks (802) are loosened, at the moment, compression springs (803) fixedly connected between the two moving blocks (802) restore to deform to enable chucks on the two moving blocks (802) to be abutted to the corresponding clamping grooves, and the positions of the moving blocks (802) are limited;
s5, finally, starting the motor (6), enabling the motor (6) to rotate to drive the fixedly connected supporting rod (7) to rotate, enabling the arc-shaped polishing plate (807) on the supporting rod (7) to polish the inner ring of the bearing, and reducing the harm of dust to workers by sucking dust generated by polishing into the dust collector (9) through the hose (10) through the dust suction head (11) in the polishing process.
