1. A tooling exchange mechanism for a machine tool comprising:
a turret mounted with a tooling holder detachably holding a tooling including a rotary tool for machining a workpiece and a tool holder for detachably holding the rotary tool; and
a turret support including a tooling detacher detaching the tooling mounted to the tooling holder from the tooling holder, wherein
the tooling holder mounted to the turret includes a tool holder holding portion for mounting the tool holder in a state where the tool holder of the tooling is retracted,
the tooling detacher of the turret support includes a pressing member that is movable forward and backward in the direction to the rear end of the tooling holder and a locking lever that is movable forward and backward in the direction parallel to the moving direction of the pressing member,
the pressing member of the tooling detacher is configured to press the rear end of the tooling holder to be able to release the retracted state of the tool holder of the tooling by the tool holder holding portion of the tooling holder,
the locking lever of the tooling detacher is engageable with an engaging projection formed on the rear end side of the tooling holder, and
the turret and the turret support are configured such that, after the pressing member of the tooling detacher comes into contact with the rear end of the tooling holder, while the locking lever of the tooling detacher detachment is engaged with the engaging projection of the tooling holder, the pressing member of the tooling detacher detachment is configured to move forward to release the retracted state of the tool holder of the tooling by the tool holder holding portion of the tooling holder so that the tooling can be exchanged.
