Abstract

PURPOSE:To facilitate the change of an indexing pitch and pitch conical angle and the exchange of a used indexing unit, by providing a column freely revolvable around a vertical shaft at the front side of a tool, and providing indexing units which hold a work on the peripheral face of the column. CONSTITUTION:This indexing device rotates per pitch the workpiece A processed by the tool 4 fitted to the horizontal spindle 3 of a bevel gear work machine. A column 5 freely revolvable at an optional angle around the vertical axial line is provided at the front side of the tool 4 and also indexing units 7 having workpiece holders 6 are provided on the peripheral face of this column 5. In the case of the machine kind change of the work A, therefore, it can be coped with by revolving the column 5 so that the indexing unit 7 in the indexing pitch conformed to the machine kind is selected at the work position opposed positively to the tool 4. In this case, it can cope with the change of a pitch conical angle as well, because of the inclination of the indexing unit 7 to the spindle 3 being able to be changed with the revolving of the column 5 as well.
