After the position of the polishing block 9 is changed, the polishing block 9 enters the guide sleeve along with the rotating block 5, and the polishing abrasive paper is in contact with the inner side wall of the guide sleeve, the driving gear 29 rotates to drive the gear ring 3 to rotate, the gear ring 3 drives the rotating block 5 to rotate through the L-shaped rod 4, and therefore the polishing block 9 rotates to polish the inner wall of the guide sleeve.
When the guide sleeve is polished, the inner wall of the guide sleeve is detected through the contact between the sensing block 12 and the inner wall of the guide sleeve, if the inner wall is flat, the sensing block 12 does not move obviously in the rotating and advancing processes, and if the inner wall moves to an irregular position, the sensing block 12 necessarily moves when contacting the irregular position, so that the sliding block 11 moves along with the inner wall, the position of the conductive block 16 is changed, the resistance value of the resistance coil 15 connected to the first electromagnet 17 is changed, the magnetic force of the first electromagnet 17 is instantly changed, the magnetic flux in the solenoid 20 is changed due to the change of the magnetic force, induction current is generated in the solenoid 20 and is supplied to the second electromagnet 23 after being amplified, the second electromagnet 23 generates magnetic repulsion force on the second magnetic plate 24, the second magnetic plate 24 impacts the piezoelectric ceramic 25, and the indicator lamp 26 is turned on, at this moment, the processing personnel observes that indicator lamp 26 lights, should represent promptly that to lead to the inner wall irregular for the wastrel, and then make in the process of polishing, detect automatically, avoid detecting alone and influence machining efficiency, after detecting the completion, second electro-magnet 23 cuts off the power supply, second electro-magnet 23 after the outage is the iron core promptly, and second magnetic plate 24 can produce magnetic attraction to it this moment, and under magnetic attraction left and right sides, second magnetic plate 24 automatic re-setting.
When polishing, through the rotation of ring gear 3, drive connecting gear 34 and rotate, connecting gear 34 drives suction gear 35 again and rotates, thereby form planetary gear, make suction gear 35 relative ring gear 3 with higher speed and reverse rotation, thereby make induced fan 37 rotate, make the interior suction that produces of dust absorption pipe 42, the dust that will polish the production adsorbs, the dust after the absorption passes through in hose 40 gets into storage piece 38, the air passes through filter screen 39 and discharges, and the dust is then unable to pass through filter screen 39, stay in storage piece 38, regularly to the dust of the collection in the storage piece 38 collect the arrangement can.
