After rough polishing is finished, the motor 26 is closed to control the rotating piece 25 to be decelerated to stop, the motor 26 is started to control the rotating piece 25 to start rotating reversely, the rotating piece 25 drives the first rotating rod 22 to rotate in the same direction, the first polishing piece 21 is driven by the first rotating rod 22 to rotate in the same direction, the first rotating rod 22 is unfolded by centrifugal force, the first fine polishing piece 214 contacts with the inner side of the flange 4 and then carries out secondary polishing on the inner side of the flange 4, the first rotating rod 22 drives the second rotating rod 24 to rotate in the same direction, the second polishing piece 23 is changed from a vertical state to a horizontal state by centrifugal force, the second heavy block 232 is distributed on the outer ring under the action of centrifugal force and is higher than the initial position, the hinge point of the second short rod 231 and the second rotating rod 24 is used as a fulcrum, the second fine polishing piece 234 is distributed on the inner ring and is lower than the initial position, the second fine polishing piece 234 contacts with the outer ring of the flange 4 and then carries out secondary polishing on the outer side of the flange 4, the fine polishing process of the flange 4 is finished, and the motor 26 is closed to control the rotating piece 25 to be decelerated to stop until polishing operation is finished.
The motor 26 may control the rotation member 25 to rotate at different speeds at which the first and second polishing members 21 and 23 are dispersed differently. The higher the rotation speed, the larger the first polishing member 21 spreads out, and after the first rough polishing member 213 or the first fine polishing member 214 contacts the inner side of the flange 4, the rotation speed is increased and the contact pressure of the first polishing member 21 with the flange 4 increases. The higher the rotation speed, the closer the second short lever 231 of the second polishing member 23 is to the horizontal state, and after the second rough polishing member 233 or the second fine polishing member 234 contacts the outer side of the flange 4, the rotation speed is increased and the contact pressure of the second polishing member 23 with the flange 4 increases. The relative positions of the first polishing member 21 and the second polishing member 23 and the flange 4 can be controlled by adjusting the rotational speed of the rotating member 25, and the contact pressure can be adjusted by adjusting the rotational speed of the rotating member 25 after the polishing mechanism 2 contacts the flange 4, thereby controlling the polishing process and the polishing strength.
The whole working flow of the invention is just the above, and the step is repeated when the invention is used next time.
