Method for detecting the flatness of a ring

Abstract

The application discloses a ring piece flatness detection method and belongs to the technical field of flatness detection. The ring piece flatness detection method comprises the following steps: placing a standard flatness detection surface of a tool clamp upward on a workbench surface; placing a ring piece on the tool clamp, and placing a protruding part around the ring piece above the standard flatness detection surface; inserting a plug gauge between each protruding part and the standard flatness detection surface to obtain the spacing of the gap between the protruding part and the standard flatness detection surface; when the spacing of the gap between each protruding part and the standard flatness detection surface is within an error value range, the ring piece is determined to be qualified; and when the spacing of the gap between the protruding part and the standard flatness detection surface exceeds the error value range, the ring piece is determined to be unqualified. Only the ring piece to be detected is placed on the tool clamp, and the plug gauge is inserted into the gap, so that whether each protruding part of the detection ring piece is on the same horizontal plane can be quickly detected.
