Air-pressure-controllable flexible grinding and polishing system

Abstract

The invention discloses an air-pressure-controllable flexible grinding and polishing system which comprises a wheel type air bag grinding and polishing tool and an air pressure control device. The wheel type air bag grinding and polishing tool comprises a hollow motor arranged in a main shaft outer shell. A hollow rotating main shaft rotating relative to the main shaft outer shell penetrates through the hollow motor. The two ends of the hollow rotating main shaft are connected with a pneumatic rotating joint and an air bag grinding and polishing wheel part. The air pressure control device comprises an air pump, an electrical proportional valve, a data collecting card, a computer and a pressure sensor which is arranged in the air bag grinding and polishing wheel part. After the air pump isstarted, air enters the air bag grinding and polishing wheel part, the pressure sensor feeds the air pressure information in the wheel type air bag back to the data collecting card in real time, and the computer controls the electrical proportional valve to output the air pressure in real time. The rapid grinding and polishing machining of a deep cavity special-shaped face can be realized, and through the characteristic that the air bag grinding and polishing wheel makes flexible contact with the deep cavity special-shaped face, certain machining precision is ensured.
