Abstract
The present disclosure relates to a tool holder to receive and lock a tool taper on a tool magazine, an unlocking device to unlock a tool taper that is received and is locked in a tool holder of this type, and a tool magazine for a machine tool comprising one or more tool holders of this type and an unlocking device of this type.
Claims16
A system comprising, in combination:
- a tool holder for receiving and locking a tool taper on a tool magazine, comprising:
- a receiver for receiving the tool taper in an axial direction of the tool holder, wherein the tool taper is received on a first side of the tool holder by the receiver;
- a locking means to lock the tool taper received in the receiver;
- and
- a first fastener for fastening the tool holder on the tool magazine,
- wherein the locking means comprises a first tightening element that is movable in the axial direction of the tool holder and that is set up to be moved in the axial direction of the tool holder from a first position into a second position, the tool taper received in the receiver being locked when the first tightening element is in the first position, and the tool taper received in the receiver being unlocked when the first tightening element is in the second position, and
- wherein the first tightening element has a surface that extends transverse to the axial direction of the tool holder, and has a first tightening portion that projects from the surface of the first tightening element, in the axial direction of the tool holder, and which first tightening portion projects from the surface of the first tightening element on a second side of the tool holder opposing the first side of the tool holder;
- and
- an unlocking device for unlocking the tool taper that is received and locked in the tool holder, the unlocking device comprising:
- a second fastener for fastening the unlocking device on the tool magazine at an unlocking position of the tool magazine;
- and
- an unlocking means to unlock the tool taper that is received and locked in the tool holder when the tool holder is at the unlocking position,
- wherein the unlocking means comprises a second tightening element that is movable in an axial direction of the unlocking device, which is coaxial with the axial direction of the tool holder, and has a second tightening portion that can be brought into an engagement state with the first tightening portion of the first tightening element, so that the second tightening portion is, in the axial direction of the tool holder, in positive non-detachable engagement with the first tightening portion of the first tightening element when the tool holder is at the unlocking position, during which positive non-detachable engagement the first tightening portion and the second tightening portion are axially movable relative to one another within limits of an axial play range, and
- wherein the unlocking means is set up to unlock the tool taper received in the receiver when the first tightening portion and the second tightening portion are in the engagement state, in that the second tightening element is in respect to the axial direction of the tool holder axially controlled and by means of the positive non-detachable engagement, moves the first tightening element from the first position into the second position.

A tool magazine for a machine tool comprising:
- one or more tool holders each comprising:
- a receiver for receiving a tool taper in an axial direction of the respective tool holder, wherein the tool taper is received on a first side of the respective tool holder by the receiver;
- a locking means to lock the tool taper received in the receiver;
- and
- a fastener means for fastening the respective tool holder on the tool magazine,
- wherein the locking means comprises a first tightening element that is movable in the axial direction of the respective tool holder and is set up to be moved in the axial direction of the respective tool holder from a first position into a second position, the tool taper received in the receiver being locked when the first tightening element is in the first position, and the tool taper received in the receiver being unlocked when the first tightening element is in the second position, and
- wherein the first tightening element has a surface that extends transverse to the axial direction of the corresponding tool holder, and has a first tightening portion that projects from the surface of the first tightening element, in the axial direction of the corresponding tool holder, and which first tightening portion projects from the surface of the first tightening element on a second side of the respective tool holder opposing the first side of the respective tool holder;
- a tool holder fastener;
- and
- a displacing device for displacing at least one of the one or more tool holders, wherein the at least one tool holder is fastened by the respective fastener means to the tool holder fastener, wherein the displacing device is set up to displace the at least one tool holder that is fastened to the tool holder fastener into an unlocking position of the tool magazine, and wherein the at least one tool holder is displaced by the displacing device in a first direction perpendicular to the axial direction of the at least one tool holder,
- an unlocking device for unlocking the tool taper that is received and locked in the at least one tool holder, the unlocking device comprising:
- a second fastener for fastening the unlocking device on the tool magazine at the unlocking position;
- and
- an unlocking means to unlock the tool taper that is received and locked in the at least one tool holder when the at least one tool holder is at the unlocking position,
- wherein the unlocking means comprises a second tightening element that is movable in an axial direction of the unlocking device, which is coaxial with the axial direction of the at least one tool holder, and has a second tightening portion that can be brought into an engagement state with the first tightening portion of the first tightening element, so that the second tightening portion is in the axial direction of the at least one tool holder in positive non-detachable engagement with the first tightening portion of the first tightening element when the at least one tool holder is at the unlocking position,
- wherein the unlocking means is set up to unlock the tool taper received in the receiver when the first tightening portion and the second tightening portion are in the engagement state, in that the second tightening element is in respect to the axial direction of the corresponding tool holder axially controlled and by means of the positive non-detachable engagement, moves the first tightening element from the first position into the second position, and
- wherein the first tightening portion is configured in such a way that the first tightening portion can be brought into the engagement state with the second tightening portion by a relative movement with respect to the second tightening portion in the first direction perpendicular to the axial direction of the at least one tool holder, when the displacing device is displacing the at least one tool holder in the first direction, perpendicular to the axial direction of the at least one tool holder, into the unlocking position.
