DEVICE FOR MEASURING COAXIAL MATCHING OF TWO CYLINDRICAL SURFACES AND CYLINDRICAL WORK TURNING MACHINE USING THIS DEVICE

摘要

Abstract of the DisclosureThis invention involves an indicator assembly and method for locatingthe position of the ends of a cylindrical workpiece in a roll turning lathein order to allow accurate adjustment of the workpiece axis position intoalignment with the turning axis of the lathe. The assembly is removablymounted on the tool slide of the lathe for radial movement into engagementwith the workpiece, and is constructed to locate the relative position ofthe workpiece and machine axes in horizontal and vertical coordinates.This apparatus is used in the method to compare the position of the cylindricalsurface of the faceplate of the lathe with the position of the surface of thejournal of the roll in the horizontal coordinate and to compare the positionof the axis of the faceplate with the position of the axis of the journal inthe vertical coordinate.
