Claims

[Claims for Utility Model Registration] (1) An indexing table on which a workpiece having a plurality of protrusions arranged at a constant pitch is placed on its outer periphery, and a drive for moving the workpiece in a straight line on the indexing table. a member, and a plurality of index pins disposed along the straight line at the same pitch as the pitch and engaged with the protrusions of the workpiece, and the protrusions and the index pins are engaged with each other while moving the workpiece. In a device for indexing the rotational position of the workpiece, the device is positioned on the opposite side of the indexing pin while holding the workpiece, allowing the workpiece to escape to the opposite side of the indexing pin, and indexing the workpiece. A rotary indexing device characterized in that it is provided with a pressing member that presses toward the pin side. (2) The pressing member is provided on the driving member so as to be rotatable about a rotation axis parallel to the axis of the workpiece on the indexing table, and the pressing member is configured to prevent the workpiece from escaping to a side opposite to the indexing pin. According to claim 1, the workpiece is engaged with the workpiece and rotated around the rotation axis, and the workpiece is pressed toward the index pin by the urging force of the urging means. rotary indexing device. (3) The rotary indexing device according to claim 1 or 2, wherein the plurality of index pins have a smaller protrusion dimension relative to the workpiece as they move upstream in the moving direction of the workpiece.
