Low for the polishing efficiency that overcomes prior art die curve polishing tool, the polishing quality is low, can not carry out On-line Control, local shape face is accurate revises cumbersome deficiency, the utility model provides a kind of polishing efficiency height, polishing quality height, is convenient to be implemented in line traffic control, is convenient to carry out the accurate self-driving air sac pressure controlled flexible furbisher of revising of local shape face.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of self-driving air sac pressure controlled flexible furbisher that is used for the die curve polishing, described polishing tool comprises that an air bag, described air bag front end have polishing cloth as working face, described air bag is installed in the retainer;
Comprise that also one makes the rotary drive mechanism of retainer rotation, described rotary drive mechanism is connected with described retainer; Described air bag is connected with outer air source inlet by gas channel, on the described gas channel overflow valve is housed.
Further, described rotary drive mechanism is a motor, and described retainer is connected with the output shaft of motor; The output shaft of described motor is a hollow pipe, the gas channel that connects outer source of the gas as air bag, outer air source inlet and overflow valve are installed on the rear end cap of described motor, the hollow pipe one end communicated air bags in the output shaft of described motor, and the other end is communicated with outer air source inlet.
Or described rotary drive mechanism also can adopt air motor, and described retainer is connected with the output shaft of air motor; The output shaft of described air motor is a hollow pipe, the gas channel that connects outer source of the gas as air bag, outer air source inlet and overflow valve are installed on the rear end cap of described air motor, the hollow pipe one end communicated air bags in the output shaft of described air motor, and the other end is communicated with outer air source inlet.
The basic principle of self-driving air sac pressure controlled flexible furbisher polishing is: utilize the motor of self-driving air sac pressure controlled flexible furbisher or air motor driving air bag to rotate at a high speed; By can regulating the flexibility of air bag, thereby make rubbing head form the flexible polishing working face to the control of air pressure of input air bag; The flexible polishing working face can form large tracts of land even contact, uniform polishing effect and high polishing efficiency when reaching curved surface polishing with free form surface easily; Self-driving air sac pressure controlled flexible furbisher is fixed on the mechanical arm of robot, can controls the polishing path of self-driving air sac pressure controlled flexible furbisher, and then realize the polishing process automation by robot on the free curve surface work pieces surface; And by the On-line Control to self-driving air sac pressure controlled flexible furbisher air bag air pressure, but the material removal amount of flexible modulation polished surface part, remedy the inexactness of the high control of robot sweep duration, help to obtain high shape face dimensional accuracy and stable normal direction polishing force, improve the burnishing surface quality.
The beneficial effect of self-driving air sac pressure controlled flexible furbisher described in the utility model mainly shows:
(1), by regulating the air pressure of air bag, can control the flexibility of polishing face, polishing tool and free form surface contact area are big, the polishing efficiency height;
(2), the feeding depth of adjusting entire tool and air bag air pressure can guarantee that the whole field method of burnishing surface is stable and relatively more even to polishing force, can obtain high polishing quality (it is following that surface roughness reaches Ra 0.020 μ m);
(3), by to the control of overflow valve air-flow, the air pressure of control air bag that can be real-time and the normal direction polishing force of curved surface can be implemented in line traffic control;
(4), by gasbag pressure control, can accurately control the local polishing removal amount, carry out that local shape face is accurate to be revised;
(5), owing to be provided with drive motors or air motor in the polishing tool, can directly drive air bag and polishing cloth rotation by motor or air motor, need only the motion path of regulating whole polishing tool by the manipulator of robot, can realize automation polishing the whole curved surface of mould.
