The present invention provides an index table apparatus which improves economic efficiency by structure simplification. The index table apparatus comprises: an index table provided with a plurality of mounting holes penetrated and formed in a circumferential direction at prescribed angular intervals, and divided and rotated at the prescribed angular intervals by a first rotary means; a jig unit installed in each mounting hole, and provided with a seating unit disposed on an upper surface thereof, on which a workpiece is seated, and a meshing protrusion which protrudes on a lower surface thereof and is exposed to a lower portion of the mounting hole; a lifting frame arranged on a lower portion of the index table to be lifted by a first lifting means, on which a second lifting means and a second rotary means are installed; and a grip rotary unit comprising a hollow shaft connected to the second rotary means to be rotated, and a plurality of finger units disposed on an upper end of the hollow shaft to grip the meshing protrusion of the jig unit transported to a prescribed machining position to be rotated, and radially tightened and spread by a vertical drive force by the second lifting means. |
