Abstract
An automatic tool changer (ATC) serves as an ATC for automatically changing a tool attached to a lower tool rest of a machine tool. The ATC includes a robot arm and a movement mechanism unit moving the robot arm between inside and outside of a machining area. The robot arm has a base unit coupled to the movement mechanism unit, an arm unit pivotably coupled to the base unit, and a gripping unit provided in the arm unit and detachably gripping the tool. The arm unit is formed to extend in an arm shape from the base unit toward the gripping unit, and swings on a pivot axis as a fulcrum relative to the base unit. By such a configuration, an ATC implementing an automatic change of a tool by a simple and compact mechanism and a machine tool including such an ATC are provided.
