ABSTRACT:
An automatic tool changing device comprises the head of a machining center and a drum vertically movably mounted on the outer end of the head, and rotatably arranged around a center shaft which is projected from the central portion of the drum to slant downwardly are a large number of arms each having an arbor holding portion at the forward end and formed in a predetermined position on the central back surface with an elongated groove adapted for engagement with a geneva drive pin, whereby when one of the arms is engaged with a main shaft or spindle in the head, the remaining arms are continuously arranged on each side of the engaged arm above a position spaced by a predetermined angle therefrom. Disposed on the back side of the arm engaged with the main shaft and the adjacent arms on both sides thereof is a pair of genevas each having the arm moving drive pin selectively engageable with the elongated groove of the adjacent pair of arms, and every rotation or every plurality of rotations of the genevas in the counterclockwise or clockwise direction moves the arms each by an amount corresponding to one arm or a plurality of the arms.
