Tool-changing device, machine tool having such a tool-changing device, and associated method

A tool-changing device (1), comprising

• at least two tool holders (2) for holding one tool (3) each,
• a drive device (4) through which
• the tool holders (2) are movable relative to at least one of a frame (5) or a base body (5a) of the tool-changing device (1) into a working position (6),
• the drive device (4) includes at least one locking element (7) and at least one counter element (8), which is connected at least indirectly to the at least two tool holders (2), and
• the at least two tool holders (2) are movable into different positions through a relative adjusting movement (22) between the locking element (7) and the counter-element (8) into the working position (6) in which the tool holders (2) are lockable, and
• the adjusting movement (22) is carried out by engagement of the locking element (7) and the counter element (8) with one another, and
• the adjusting movement (22) positions the tool holders (2) into the working position (6),
• such that the respective tool holder (2) is positionable into the working position (6) in a positioning movement (21) when the locking element (7) and the counter element (8) are locked together.
