Description
- The present invention relates to a polishing equipment for spherical body.
- For many spherical products, in order to obtain a smooth surface and a true circle of the spherical body, it is usually necessary to perform grinding and polishing on the surface of the spherical product. In order to effectively stabilize the spherical product and to grinding and polishing of an entirety of the surface of the spherical product, a conventional polishing device includes at least three grinding units and at least a rotating unit for rotating the spherical product. The at least three grinding units are angularly arranged around the spherical product for respectively grinding and polishing different areas of the spherical product, and the at least a rotating unit is configured for causing the spherical product rotate, with a slight deflection angle relative to the vertical direction so as to ensure that the at least three grinding units can indeed grind all areas of the surface of the spherical product. TW201436935 discloses a like conventional polishing device.
- However, the structure of this type of conventional polishing device is extremely complex and the manufacturing cost is high. In addition, the coordination between multiple grinding units and rotating unit is not easy to accurately control, and errors are prone to occur, resulting in problems of poor polishing efficiency, poor polishing stability, poor smoothness and poor roundness.
- The present invention is, therefore, arisen to obviate or at least mitigate the above-mentioned disadvantages.
- The main object of the present invention is to provide a polishing equipment for a spherical body, wherein the polishing equipment has a simple structure and can provide good polishing efficiency, stability and quality.
- To achieve the above and other objects, a polishing equipment for a spherical body is provided, including: a base, including a tubular member configure to support the spherical body to be polished; a fluid pressurizing unit, being in communication with an interior of the tubular member and configure for fluid to flow into the interior of the tubular member to push the spherical body; a grinding member, configured to be relatively movable with respect to the tubular member, and configured for grinding an outer surface of the spherical body and rotating the spherical body by friction.
- The present invention will become more obvious from the following description when taken in connection with the accompanying drawings, which show, for purpose of illustrations only, the preferred embodiment(s) in accordance with the present invention.
