Abstract
Description
Diese selektive Kühlvorichtung dient zur einfachen und rationellen Lösung von Kühl- und Schmierpro blemen an Werkzeugmaschinen, Probleme wie durch DE-P 36 17 540.4 bereits bekannt.This selective cooling device is used for simple and rational solution of cooling and lubrication pro blemish on machine tools, problems like through DE-P 36 17 540.4 already known.
Der Erfindung liegt die Aufgabe zugrunde, daß der gleiche Werkzeughalter (1) und die gleiche Reduzierhülse (2) einer Werkzeugmaschine sowohl für ein außengekühltes Werkzeug (7) als auch für ein innengekühltes Werkzeug (11) zur Zu führung des Kühlmediums verwendet wird. Die Werkzeuginvestitionskosten werden hierdurch um die Hälfte reduziert.The invention has for its object that the same tool holder ( 1 ) and the same reducing sleeve ( 2 ) of a machine tool for both an externally cooled tool ( 7 ) and for an internally cooled tool ( 11 ) is used to guide the cooling medium. This reduces tool investment costs by half.
Diese selektive Kühlvorrichtung wird durch eine in oder am Werkzeughalter (1) angebrachte Kühl mediumsweiche (4) ermöglicht.This selective cooling device is made possible by a cooling medium switch ( 4 ) mounted in or on the tool holder ( 1 ).
Die Kühlmediumsweiche (4) wird durch den mit der Werkzeugmaschine verbundenen Werkzeughalter (1) und den Kanal zur Kühlmediumsweiche (3) mit unter Druck stehendem Kühlmedium versorgt.The coolant switch ( 4 ) is supplied with pressurized coolant by the tool holder ( 1 ) connected to the machine tool and the channel to the coolant switch ( 3 ).
Die selektive Kühlung der Werkzeugschneiden (14) eines außengekühlten Werkzeuges (7) wird durch die Sperrung des Kühlmittelkanals I 1 (8) durch Verdrehung um vorzugsweise 90 Winkelgrad des in der Reduzierhülse (2) befindlichen Kühlmedium kanal I 2 (9) und die Öffnung der in Richtung der Werkzeugschneiden (14) ausgerichteten Stell kugel für Kühlmedium (6) ermöglicht). (Fig. 1, 3). Das Kühlmedium fließt über den Kanal zur Kühl mediumsweiche (3) über die Kühlmediumsweiche (4), durch den Kühlmediumskanal A (5) und die Stell kugel für Kühlmedium (6) auf die Werkzeugschnei den (14) des außengekühlten Werkzeugs (7), wel ches in der Reduzierhülse (2) fixiert ist (Fig. 1, 3).The selective cooling of the tool cutting edge (14) is an externally-cooled tool (7) by blocking the coolant passage I 1 (8) by rotation through preferably 90 angular degrees of the cooling medium located in the bushing (2) channel-I 2 (9) and the opening of the in the direction of the tool cutting ( 14 ) aligned adjusting ball for cooling medium ( 6 ) allows). ( Fig. 1, 3). The cooling medium flows through the channel to the cooling medium switch ( 3 ) via the cooling medium switch ( 4 ), through the cooling medium channel A ( 5 ) and the adjusting ball for cooling medium ( 6 ) on the tool cutting edges ( 14 ) of the externally cooled tool ( 7 ), wel ches in the reducing sleeve ( 2 ) is fixed ( Fig. 1, 3).
Die Werkzeugschneiden (14) eines innengekühlten Werkzeuges (11) können auf oben genannte Art auch zwangsweise nur von außen mit Kühlmedium versorgt werden.The tool cutting edges ( 14 ) of an internally cooled tool ( 11 ) can also be forcibly supplied with cooling medium only from the outside in the above-mentioned manner.
Die selektive Kühlung der Werkzeugschneiden (14) eines innengekühlten Werkzeuges (11) wird durch die Sperrung der Stellkugel für Kühlmedium (6), vorzugsweise durch Drehung um 90 Winkelgrad, durch den mit Kühlmediumskanal I 2 (9) verbun denen Kühlmediumskanal I 1 (8), sowie durch den Kühlmediumskanal im Werkzeug (10) ermöglicht (Fig. 2, 4).The selective cooling of the tool cutting edges ( 14 ) of an internally cooled tool ( 11 ) is achieved by blocking the actuating ball for the cooling medium ( 6 ), preferably by rotating through 90 degrees, through the cooling medium channel I 1 ( 8 ) connected to the cooling medium channel I 2 ( 9 ). , as well as through the cooling medium channel in the tool ( 10 ) ( Fig. 2, 4).
Das Kühlmedium fließt über den Kanal zur Kühl mediumsweiche (3), über die Kühlmediumsweiche (4), durch den Kühlmediumskanal I 1 (8), durch den Kühlmediumskanal I 2 (9), durch den freien Innen raum (15) der Reduzierhülse (2) und den Kühl mediumskanal im Werkzeug (10) auf die Werkzeug schneiden (14) des innengekühlten Werkzeugs (11), welches in der Reduzierhülse (2) fixiert ist (Fig. 2, 4).The cooling medium flows via the channel to the cooling medium switch ( 3 ), via the cooling medium switch ( 4 ), through the cooling medium channel I 1 ( 8 ), through the cooling medium channel I 2 ( 9 ), through the free interior ( 15 ) of the reducing sleeve ( 2 ) and the cooling medium channel in the tool ( 10 ) on the tool cut ( 14 ) of the internally cooled tool ( 11 ), which is fixed in the reducing sleeve ( 2 ) ( Fig. 2, 4).
Die Kühlung der Werkzeugschneiden (14) eines innengekühlten Werkzeugs (11) wird auch durch die Öffnung der in Richtung der Werkzeugschnei den (14) ausgerichteten Stellkugel für Kühl medium (6) und durch den mit Kühlmediumskanal I 2 (9) verbundenen Kühlmediumskanal I 1 (8), sowie durch den Kühlmediumskanal im Werkzeug (10) ermöglicht, es liegt demnach paralelle Innen- und Außenkühlung vor.The cooling of the tool cutting edges (14) of an internally cooled tool (11) through the opening in the direction of the Werkzeugschnei the (14) aligned detent ball for the cooling medium (6) and by the related cooling medium passage I 2 (9), cooling medium passage I 1 ( 8 ), as well as through the cooling medium channel in the tool ( 10 ), so there is parallel internal and external cooling.
Die Befestigung des Werkzeugs (7, 11) in der Reduzierhülse (2) und im Werkzeughalter (1) erfolgt durch die in die Bohrungen (13) ragen den Werkzeugbefestigungen (12) (Fig. 1 bis 4).The tool ( 7 , 11 ) is fastened in the reducing sleeve ( 2 ) and in the tool holder ( 1 ) by the tool fastenings ( 12 ) projecting into the bores ( 13 ) ( FIGS. 1 to 4).
Durch die richtige Paarung der vorzugsweise um 90 Winkelgrad versetzten Bohrungen (13) und Werkzeugbefestigungen (12) läßt sich die Ver bindung bzw. Trennung der Kühlmediumskanäle I 1 (8) und I 2 (9) genau definiert fixieren.Through the correct pairing of the bores ( 13 ) and tool fastenings ( 12 ), which are preferably offset by 90 degrees, the connection or separation of the cooling medium channels I 1 ( 8 ) and I 2 ( 9 ) can be fixed in a precisely defined manner.
