Automatic tool changing apparatus.

摘要

The spindle axis (Z) and the tool axis (X) at a tool changing station of a magazine proper (6) cross at right angles with a spacing therebetween. An automatic tool changing apparatus (7) is positioned in the space and is swingeable about an inclined shaft (12). A member (14) is movable forward and backward on a base (13) mounted on the shaft (12). An arm (17) having tool gripping claws (15,16) at opposite ends is carried by a movable frame (31) on member (14) so as to make a half turn and to move in and out perpendicular to the direction (Y) of movement of member (14), the gripping claws (15,16) crossing the spindle axis (Z) and the tool axis (X) at right angles. This series of movement effects automatic tool changing rapidly and provides a large number of tool pots in a small space.
