Title: Automatic bladed tool changer

Abstract: A floating cylinder 12 and a rotating shaft fixing cylinder 11 are attached to a flange RB1 at the distal end of a robot arm via an attaching member 17. Attached to the floating cylinder 12 is a rotary tool 10. To mount or demount a bladed tool to or from a collet chuck 13, the rotating shaft fixing cylinder 11 is operated to advance a stopper 15 so that a rotating shaft 14 of the rotary tool is locked. The chuck nut of the collet chuck 13 is inserted and fixed into a collet fixing groove in which the bladed tool is stored. The robot is operated so as to rotate the flange RB1, by which the rotating shaft 14 and the chuck nut of the collet chuck 13 are rotated relatively to tighten or loosen the bladed tool in the collet chuck 13.
