Tool changer

A tool changer comprising:

• a slider configured to be provided on a surface of a table of a press brake, and configured to slide in a right-left direction along a tool installation part of the table,
• a finger provided in the slider, configured to be inserted into an engagement hole extending through a tool and to move in a front-rear direction, the front-rear direction being perpendicular to the surface of the table of the press brake, and the finger being configured to support the tool,
• an engagement member configured to be swingable such that it may be protruded and retracted relative to an outer peripheral surface of the finger at a tip end of the finger, and to be engaged with a peripheral edge of the engagement hole of the tool or with an inner stepped portion formed within the engagement hole of the tool, and
• an operation rod that is provided in the finger so as to be movable in the front-rear direction and is configured to push and pull the engagement member to swing the engagement member,
• wherein the finger includes:
• a larger-diameter portion that is formed at a base end of the finger,
• a smaller-diameter portion that is formed at the tip end of the finger and has a diameter smaller than a diameter of the larger-diameter portion, the smaller-diameter portion being configured to be inserted into the engagement hole of the tool, and
• an outer stepped portion that is formed at a boundary between the larger-diameter portion and the smaller-diameter portion and is configured to abut on the tool, and
• wherein the finger is configured to clamp the tool between:
• (a) the engagement member that is protruded from the outer peripheral surface of the finger and (b) the outer stepped portion when the finger has been inserted into the engagement hole of the tool and then the engagement member has been protruded from the outer peripheral surface of the finger.
