A BRUSH UNIT, A DEVICE FOR BRUSH-POLISHING THAT USES THE BRUSH UNIT, A SYSTEM FOR BRUSH-POLISHING, AND A METHOD FOR BRUSH-POLISHING

摘要

The purpose of the present invention is to provide a device for brush-polishing by means of a polishing brush that rotates and revolves as in a planetary motion, wherein the conditions to polish can be easily set in accordance with the properties of the workpiece and the purposes to polish. A brush unit has a polishing brush that rotates and revolves. The brush unit includes a mechanism for driving the rotation that rotates the polishing brush and the mechanism for driving the revolution that revolves it. By adjusting the speed of the rotation by the mechanism for driving the rotation the capabilities to polish the workpiece are enhanced. By adjusting the speed of the revolution by the mechanism for driving the revolution the entire workpiece is uniformly polished.

主权项

1. A brush unit to polish a surface of a workpiece to be polished by means of a polishing brush that rotates and revolves in a planetary motion comprising:
a polishing brush, wherein tips of a plurality of bristles are exposed from a bottom of the polishing brush; a rotating unit having
a mechanism for rotation having a rotating shaft that is connected to the polishing brush at one end, a sliding shaft, through which the rotating shaft is inserted so that the rotating shaft can be rotated, and a holder for rotation, through which the sliding shaft is slidably inserted,a mechanism for driving the rotation that generates a force for the rotating for rotating the polishing brush about the rotating shaft,a mechanism for transmitting the force for the rotation that transmits the force for the rotating to the rotating shaft, and a mechanism for vertically moving that moves the polishing brush toward the surface of the workpiece to be polished by means of the sliding shaft; a revolving unit that is combined with the rotating unit, the revolving unit having
a mechanism for a revolution that rotates so as to revolve the polishing brush,a mechanism for driving the revolution that generates a force for the revolution to revolve the polishing brush, anda mechanism for transmitting the force for the revolution that transmits the force for the revolution to the mechanism for driving the revolution.
