Claims (17)
- - einem Gehäuse (2), einem Motor (3) zum drehenden Antrieb einer Werkzeugspindel (5),
- - einem Werkzeughalter (6) zur Aufnahme eines Werkzeugs (7), wobei der Werkzeughalter (6) drehfest mit der Werkzeugspindel (5) verbunden ist, und
- - einer Arretiervorrichtung (8), welche eine Drehmomentübertragung von dem Motor (3) auf den Werkzeughalter (6) erlaubt und eine Drehmomentübertragung von dem Werkzeughalter (6) auf den Motor (3) blockiert, wobei die Arretiervorrichtung (8)
- - ein abtriebseitiges Element (12), das mit dem Werkzeughalter (6) in Antriebsverbindung steht und wenigstens einen radial nach außen weisenden Mitnehmervorsprung (13) aufweist;
- - wenigstens eine anfriebseitige Klaue (11), die mit dem Motor (3) in Antriebsverbindung steht und mit deren Hilfe das antriebseitige Drehmoment über den Mitnehmervorsprung (13) auf das abtriebseitige Element (12) übertragbar ist,
- - einen Arretierkörper (14), der das abtriebseitige Element (12) mit seinem Innenumfang (16) umgibt und drehfest gegenüber dem Gehäuse (2) abgestützt ist, und
- - wenigstens zwei Klemmkörper (15), die zwischen dem Lnnenumfang (16) des Arretierkörpers (14) und dem abtriebseitigen Element (12) angeordnet sind und mit deren Hilfe das abtriebseitige Element (12) gegenüber dem Arretierkörper (14) selbsttätig verklemmbar ist, wenn in der einen oder der anderen Drehrichtung eine Drehmomentübertragung von dem Werkzeughalter (6) auf das abtriebseitige Element (12) stattfindet,
dadurch gekennzeichnet, dass
beidseits des Mitnehmervorsprungs (13) jeweils ein Klemmkörper (15) in derjenigen Umfangsrichtung betrachtet, die der Drehrichtung der antriebseitigen Klaue (11) bei Drehmomentübertragung von der Klaue (11) auf den Mitnehmervorsprung (13) entspricht, zwischen der antriebseitigen Klaue (11) und dem Mitnehmervorsprung (13) angeordnet ist, wobei einer der Klemmkörper (15) die Verklemmung in der einen Drehrichtung und der andere der Klemmkörper (15) die Verklemmung in der anderen Drehrichtung bewirkt.1. Machine tool ( 1 ) with
- - a housing ( 2 ), a motor ( 3 ) for rotatingly driving a tool spindle ( 5 ),
- - A tool holder ( 6 ) for receiving a tool ( 7 ), the tool holder ( 6 ) being non-rotatably connected to the tool spindle ( 5 ), and
- - A locking device ( 8 ) which allows a torque transmission from the motor ( 3 ) to the tool holder ( 6 ) and blocks a torque transmission from the tool holder ( 6 ) to the motor ( 3 ), the locking device ( 8 )
- - An output-side element ( 12 ) which is in drive connection with the tool holder ( 6 ) and has at least one radially outwardly facing driver projection ( 13 );
- - At least one claw ( 11 ) on the drive side, which is in drive connection with the motor ( 3 ) and by means of which the drive-side torque can be transmitted via the driver projection ( 13 ) to the output-side element ( 12 ),
- - A locking body ( 14 ) which surrounds the output-side element ( 12 ) with its inner circumference ( 16 ) and is rotatably supported against the housing ( 2 ), and
- - At least two clamping bodies ( 15 ) which are arranged between the inner circumference ( 16 ) of the locking body ( 14 ) and the output-side element ( 12 ) and by means of which the output-side element ( 12 ) can be automatically clamped relative to the locking body ( 14 ) if Torque is transmitted from the tool holder ( 6 ) to the output-side element ( 12 ) in one or the other direction of rotation,
characterized in that
on both sides of the driver projection ( 13 ), a clamping body ( 15 ) is considered in the circumferential direction that corresponds to the direction of rotation of the drive-side claw ( 11 ) when torque is transmitted from the claw ( 11 ) to the driver projection ( 13 ), between the drive-side claw ( 11 ) and the driver projection ( 13 ) is arranged, one of the clamping bodies ( 15 ) causing the jamming in one direction of rotation and the other of the clamping bodies ( 15 ) causing the jamming in the other direction of rotation.
