A tooling exchange mechanism and a machine tool having the tooling exchange mechanism, in which a load applied to a turret is reduced when exchanging a tooling in the machine tool, are provided with a pressing memberof a tooling detachment unitthat presses the rear end of a tooling holding unitto be able to release the retracted state of a tool holder Th of a tooling T by a tool holder holding portionof the tooling holding unit, and a locking leverof the tooling detachment unitengageable with an engaging projectionformed on the rear end side of the tooling holding unit

Tooling exchange mechanism and machine tool having the tooling exchange mechanism

A turret tool post includes a turning part having a plurality of turret surfaces on which tools for machining a workpiece are mounted, the turning part being configured to select any one of the tools for use in the machining of the workpiece by turning; a non-turning part on which a laser head of a laser machining device different from the tool is mounted, the non-turning part being arranged inside the turning part, an optical fiber cable being connected to the laser head; and a cut part (machinable part) that allows machining by the laser head to the workpiece under a state in which the laser head is selected.

Turret tool post

A turret tool post includes a turret turnably supported by a post body, turret turning part having a turret turning shaft and the like to turn the turret, a tool attachment part turnably holding a rotatable tool and attached to the turret, and tool-attachment-part turning part turning the tool attachment part to turn the rotatable tool. The tool-attachment-part turning part and the turret turning part are provided independently and arranged to face each other. The tool-attachment-part turning part includes a tool turning motor installed inside the turret and an attachment-part transmission shaft connected to the tool turning motor.

Nameplate

A first driving force transmission part is disposed between an attachment part turning transmission shaft and a tool attachment part. The first driving force transmission part transmits rotary driving force from a side of the attachment part turning transmission shaft to the side of the first turning driving force transmission shaft, and includes a groove, a tenon shaped protrusion, and protrusions. The groove is formed on a tip of a slide shaft of the attachment part turning transmission shaft. The tenon shaped protrusion is formed in the first turning driving force transmission shaft and detachably engages with the groove. The protrusions once releases an engaging posture by pressing the groove that is biased to the engaging posture in an disengaging state when the tool is in the middle of the movement to a predetermined position.
