Abstract
A tool changer, used for exchanging tools between a tool magazine and a tool spindle of a machine tool, includes a tool-changing unit and a feed screw. The tool-changing unit has a rotating shaft with a changing arm attached to one end thereof and a rotating drive motor attached to the other end thereof. The feed screw has one end to which a drive motor is attached to cause the tool-changing unit to perform a feed operation of a tool and also perform detachment/attachment of the tool by utilizing the feed operation. Additionally, the feed screw is parallel to a rotational axis of the tool spindle positioned at a tool-changing position.

A tool changer used for exchanging tools between a tool magazine and a tool spindle of a machine tool, comprising:
- a tool-changing unit including a rotating shaft, with a changing arm attached to one end of said rotating shaft and a rotating drive motor attached to the other end of said rotating shaft;
- and
- a feed screw having one end to which a drive motor is attached to cause said tool-changing unit to perform a feed operation of a tool and also perform detachment/attachment of the tool by utilizing said feed operation, wherein
- said feed screw is parallel to a rotational axis of the tool spindle positioned at a tool-changing position.
A tool changer comprising:
- a tool-changing unit including a rotating shaft, with a changing arm attached to one end of said rotating shaft and a rotating drive motor attached to the other end of said rotating shaft;
- a straight guide rail for guiding said tool-changing unit in a shift direction;
- and
- a feed screw having one end to which a drive motor is attached to shift said tool-changing unit along said guide rail to perform a feed operation of a tool, wherein
- said drive motor rotates said feed screw to cause said tool-changing unit to shift from a storing position and stop at a tool delivery position where a tool is detached /attached from a tool magazine and at a tool-changing position where the tool is detached/attached to a tool spindle, while rotation of said feed screw is utilized to perform detachment/attachment of the tool at said tool delivery position as well as at said tool-changing position, and
- said tool-changing unit rotates said changing arm at said tool delivery position as well as at said tool-changing position.
