Description

Während der Bohrkopf nach dem Patent 684469 zur Herstellung durchgehender Bohrungen bestimmt ist, also solcher, die an beiden Enden offen sind, wird nachstehend eine Abwandlung dieser Bauart gezeigt, mit welcher auch Bohrungen ausgeführt werden können, die an einem Ende ganz oder teilweise geschlossen sind. While the drill head according to patent 684469 is intended to produce through bores, i.e. those that are open at both ends, a modification of this type is shown below, with which bores can also be made that are completely or partially closed at one end.

Ein solcher Bohrkopf ist beispielsweise in Abb. i im Längsschnitt gezeigt.Such a drill head is shown in longitudinal section, for example, in Fig. I shown.

Das Schneidwerkzeug 5 ist schräg gesteilt und ragt vorn und seitlich über den Umriß des Werkzeughalters ,4 heraus, so daß auch scharfe Ecken ausgebohrt werden können.The cutting tool 5 is inclined and protrudes front and side over the outline of the tool holder, 4 out, so that even sharp corners are drilled out can be.

Der ganze Bohrkopf mit Werkzeughalter q. und Kegelteil 3 ist auf das glatte Ende g der Bohrstange Io geschoben. Diese Bohrstange läuft in einer Führungsbuchse i i, die in einem Bohrkasten sitzt. Der Sockel i des Bohrkopfes trägt einen kegelförmigen, schwachausmittigen Längsschlitzen 8 versehen; zur Übertragung der Drehkraft dient der Kei12. Der Rand des Sockels i sowie der benachbarte Rand des Werkzeughalters 4. sind mit Einteilungen versehen, um den Bohrkopf einstellen zu können.The whole drill head with tool holder q. and cone part 3 is on that smooth end g of the boring bar Io pushed. This boring bar runs in a guide bush i i sitting in a drill box. The base i of the drill head carries a conical, provided slightly eccentric longitudinal slots 8; serves to transmit the torque the Kei12. The edge of the base i and the adjacent edge of the tool holder 4. are provided with graduations in order to be able to adjust the drill head.

Die Kopfschraube 7 dient dazu, den Werkzeughalter q. gegen den Kegelteil 3 festzuziehen, ohne daß sie über den Werkzeughalter hervorsteht. Dessen Bohrung verengt sich dabei etwas, was ,aber nicht zum Erfindungsgegenstand gehört, so daß der Sockel i ,fest und sicher auf der Bohrstange sitzt.The head screw 7 is used to hold the tool holder q. against the cone part 3 without protruding from the tool holder. Its bore narrows something that, but does not belong to the subject matter of the invention, so that the base i, sits firmly and securely on the boring bar.

Ein in den Werkzeughalter. eingeschraubter Ring 12 ,erleichtert das Lösen des Bohrkopfes insofern, als heim Rückwärtsdrehen der Schraube 7 sich ihr Bund gegen den. Ring 12 legt und damit den Werkzeughalte 4 vom Kegelteil 3 abhebt.One in the tool holder. screwed-in ring 12 makes this easier Loosening the drill head insofar as home turning the screw 7 backwards her Covenant against the. Ring 12 sets and thus the tool holder 4 lifts off the conical part 3.

Abb. 2 ist eine Stirnansicht des Sockels i mit dem geschlitzten, um das Maß e ausmittigen Kegelteil 3. Fig. 2 is a front view of the base i with the slotted cone part 3 off-center by the dimension e.

PATENTANSPRUCH: Mittels Exzenterbewegung verstellbarer Bohrkopf zur Verwendung auf glatten Bohrstangen, bei dem ein ringförmiger Werkzeughalter auf einem .auf die Bohrstange aufsetzbaren und zur Bohrungsachse ausmittigen, längs geschlitzten Kegelteil drehbar ist und bei dem zugleich mit dem Festlegen des Werkzeughalters auf dem Kegelteil dessen Festklemmen auf der Bohrstange bewirkt wird, nach Patent 68¢ 469, dadurch gekennzeichnet, daß der Werkzeughalter (q.) an dem dem verjüngten Ende des Kegelteils (3) entsprechenden Ende versenkt eine Kopfschraube (7) trägt.PATENT CLAIM: Drill head adjustable by means of an eccentric movement for Use on smooth boring bars that have an annular tool holder on one. can be placed on the boring bar and off-center to the bore axis, lengthways slotted cone part is rotatable and at the same time with the setting of the tool holder on the cone part whose clamping is effected on the boring bar, according to the patent 68 ¢ 469, characterized in that the tool holder (q.) On the tapered End of the conical part (3) corresponding end countersunk a cap screw (7) carries.
