Further, described electric pneumatic adjustable flexible polishing tool also comprises the upper bearing plate that is used to support described vee-block, the lower support plate that is used to support described motor, described upper bearing plate all is connected with described turning cylinder by bearing with lower support plate, and described air bag is fixed by the air bag retainer ring.
Further, described air bag retainer is by key and mark closely screw and be connected with described turning cylinder.
Operation principle of the present utility model is: high pressure draught enters snorkel from the adjusting of outer source of the gas mouth by pressure-reducing valve, and then enters air bag by rotary inlet suction port, turning cylinder, air bag retainer.The surface attachment of air bag has polishing cloth, drives turning cylinder at motor after the transmission mechanism transmission and rotates at a high speed, and the related polishing cloth of air bag forms large tracts of land with Free Surface and contacts, thereby can obtain uniform polishing effect and high polishing efficiency.By adjusting to pressure-reducing valve, can control the air pressure of air bag and the normal direction polishing force of curved surface in real time, be implemented in line traffic control; By the pressure control of air bag, accurately control the local polishing removal amount, carry out the precision correction of local shape face.
The beneficial effects of the utility model are: 1. polishing tool is self-powered, has saved external driving, can enlarge the adaptive surface of instrument, is used with various robots easily;
2. regulate the flexibility of polishing face by the adjusting of air bag air pressure, polishing tool and free form surface contact area are big, the polishing efficiency height;
3. regulate each free degree of robot, can realize the requirement of polishing locus easily, guarantee that the normal direction polishing force in the whole zone of burnishing surface is stable and even, to obtain high polishing quality;
4. by control, can control the air pressure of air bag and the normal direction polishing force of curved surface in real time, be implemented in line traffic control the external pressure-reducing valve of snorkel;
5. by control, can accurately control the local polishing removal amount, and then realize the precision correction of local shape face gasbag pressure;
6. regulate the automation that relative position between polishing tool and the polishing workpiece is realized polishing process by regulating robot.
