This machine tool is provided with an arm for exchanging a tool between a main shaft in a machining chamber and a secondary tool standby position in a tool holding chamber, a shutter which is provided in an opening defined in a wall which partitions between the machining chamber and the tool holding chamber, a first motor for opening and closing the shutter, a shutter position detector which can detect the position of the shutter in the entire range between the fully open position and the fully closed position, a storage device which stores a prescribed position of the shutter associated with a prescribed operation of the arm and a control device which is configured to perform a prescribed operation of the arm on the basis of the position of the shutter detected by the shutter position detector and the prescribed position of the shutter stored in the storage device.

A conveyance chain comprises a plurality of link plates alternately coupled and conveying plural tool pots each holding a tool. The plurality of link plates include an inner link plate and an outer link plate each including a rotation stop hole that stops a rotation of the tool pot and a rotation permit hole located upstream from the rotation stop hole with respect to a conveyance direction that permits a rotation of the tool pot. The plurality of tool pots includes a first tool pot and a second tool pot, the first tool pot is inserted through a rotation stop hole of the inner link plate and a rotation permit hole of the outer link plate, and adjacent to the first tool pot, the second tool pot is inserted through a rotation permit hole of the inner link plate and a rotation stop hole of the outer link plate.

Provided is a tool magazine apparatus capable of preventing a phase error in attaching a tool to a tool holding gripper. A tool magazine apparatus includes: a magazine body having both front and rear racks each provided with tool holding grippers; a tool transfer device to take out a tool from the both racks and attach a tool to the both racks; a tool standby pot to hold a tool; and an intra-magazine tool change device to deliver a tool between the tool standby pot and the tool transfer device. The tool transfer device includes: a moving body disposed between the both racks; a base disposed on the moving body and being rotatable around an axis extending in the Z-axis direction; a transfer gripper attached to the base and being movable in a plane orthogonal to the Z-axis direction; and an air cylinder causing the transfer gripper to move.

This tool conveying device is provided with an indexing device comprising an input shaft, a first output shaft, and a second output shaft which is positioned adjacent and parallel to the first output shaft, wherein the input shaft is linked to a servo motor, the first output shaft rotates during rotation of the input shaft and the second output shaft stops at a prescribed angular position in a certain period during rotation of the input shaft and rotates in the remaining period during said rotation of the input shaft; a gripper; a turning part which is driven by the second output shaft of the indexing device and which supports the gripper; and a gripper opening/closing member which is driven by the first output shaft of the indexing device.

The present disclosure relates to a tool magazine for a machine tool, and more particularly, to a tool magazine for a machine tool, wherein tool receiving units of a tool magazine are provided in multiple stages in a vertical turning center, such that a spindle head may easily change internal diameter machining tools and external diameter machining tools while moving in a horizontal direction and a vertical direction.

Provided is a tool pot overcoming a problem that dirt adhered to the tool pot is transferred to a contact face of a tool. A pull stud holder includes a pusher that moves in a direction orthogonal to an axis of the tool whereby a tapered face provided at a distal end of the pusher pushes a tapered face of a pull stud in an axial direction of the tool. A base member includes a pull stud receiver that receives an end face of the pull stud. The pusher and the pull stud receiver prevent rotation of the pull stud and movement thereof in the axial direction of the tool. A flange holder includes a key that fits into a keyway of a flange, thereby preventing rotation of the flange.

Provided is a compact tool changer. The vertical machine tool includes a frame, a spindle, a moving device for moving the spindle, a magazine including a plurality of pots that move up and down installed in a pot holder, a pot lifter for moving up and down the pot at a pot tool changing position, and an intermediate arm assembly that moves among a magazine position, an intermediate position, and a spindle position. The intermediate arm assembly includes an arm having a first gripper and a second gripper, and an arm rotation device for positioning the first gripper or the second gripper to either a pot phase or a spindle phase.

This machine tool system is provided with a tool holder adaptor that has a flange having formed therein: a hole part that contains a tool holder; and an engagement part that engages with a hand of a self-propelled robot, wherein when transporting the tool holder to a machine tool from a tool storage that contains a plurality of tool holder adaptors, the self-propelled robot grasps the tool holder adaptor to transport the tool.

The invention relates to a clamping device (10) for a tool (18) on a machine tool having a holder block (12) with at least 2, in particular a multiplicity of, apertures (16) for receiving clamping sleeves (14), wherein at least two clamping sleeves (14) are received in the apertures (16). Each clamping sleeve (12) has a clamping element (36), with which a tool (18), in particular a shaft (20) of a tool (18), can be clamped. The clamping sleeve (14) at least partially passes through in each case the aperture (16) in the holder block (12) and has, at its end opposite the clamping element (36), the rear end, an expansion element (34) which engages behind the holder block (12) or a counter-support element (30) of the holder block (12).

An example pod for tool storage comprises: an elongated body; a cavity formed within the elongated body, wherein the cavity has a geometric shape that matches a shape of a tool body of a tool to be stored in the pod; an opening in the elongated body, wherein the opening has a respective geometric shape that matches a shape of a cutting end of the tool; at least one male feature formed on an exterior surface of the elongated body to facilitate coupling the pod to another pod; and at least one female feature formed on the exterior surface of the elongated body facilitate coupling the pod to another pod.
