ABSTRACT:
An automatic tool changing device (30) has a tool storage device (31) with a plurality of tools stored therein, a tool chucking unit (41) and a tool unchucking unit (51) both capable of advancing/retreating between the tool storage device (31) and a tool changing position (P2), and a tool delivery mechanism (61). The tool chucking unit (41) is provided with a tool fastening mechanism (42) for fastening the tool chucking mechanism (24), and the tool unchucking unit (51) is provided with a tool loosening mechanism (52) for loosening the tool chucking mechanism (24). The tool delivery mechanism (61) delivers the tool positioned at a tool delivery position from the tool storage device into the tool fastening mechanism of the tool chucking unit so that the tool is held by the tool fastening mechanism, and delivers the tool retrieved by the tool unchucking unit from the tool unchucking unit to the tool storage device so that the tool is stored by the tool storage device.
