Description
본 발명은 유압 펌프의 로터나 실린더 블록 등 각종 공작물의 외경구면이나 내경곡면을 가공하는 연마장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a polishing apparatus for processing the outer or spherical surface and the inner diameter curved surface of various workpieces such as a rotor or cylinder block of a hydraulic pump.

The method of processing a spherical surface by moving to an arc shape around a fixed pin in front of a workpiece | work, and the method of grinding a spherical surface using the cylindrical grinding wheel in which the cutting surface of a grinding | polishing stone is circular and the center part is recessed.
상기의 방법 중 원호형상으로 드레싱한 연마석을 이용하는 방법은 연마석을 장시간 사용할 경우 연마석의 둘레에 형성된 원호부가 점차적으로 마모됨으로서 정밀한 구면 형성이 어려워진다는 점과 연마할 구면의 직경에 따라 각각의 연마석을 준비하여야 한다는 문제점이 있었으며 원형판의 연마석을 이용하는 방법은 연마코자 하는 구면의 구 중심이 커질 경우 연마석을 원호상으로 이동시키는 장치의 구 중심 설정이 곤란해진다는 문제점이 있었고, 연마석의 절삭면이 원형이면서 중앙부가 요입된 원통형의 연마석을 이용하는 방법에는 여러가지 종류가 있으나 그 중 하나인 연마석과 피가공물을 직교하는 방향에서 각각 회전시키면서 피가공물은 고정위치에서 회전기구에 의해 회전되고 연삭숫돌은 직교방향으로 전·후 이동하여 가공하게 된 것은 구 중심 반경이 커질 경우 가공하기 어렵다는 문제점이 있었다.In the above method, the abrasive stone dressing in the shape of arc is used to prepare each abrasive stone according to the diameter of the spherical surface to be polished because the arc formed around the abrasive stone gradually wears out when the abrasive stone is used for a long time. The method of using the abrasive stone of the circular plate has a problem that it is difficult to set the sphere center of the device for moving the abrasive stone to the arc shape when the sphere center of the spherical surface to be polished becomes large, and the cutting surface of the abrasive stone is circular There are many kinds of methods to use cylindrical abrasive stones that are indented, but the workpiece is rotated by the rotating mechanism at the fixed position while the abrasive stone and the workpiece are rotated in the orthogonal direction, respectively, and the grinding wheel is moved in the orthogonal direction. Processed after moving If two central radius larger had a difficulty in processing problems.
