- the drill 17 After completion of the drilling process, the drill 17 is out of the borehole again 13 extended and takes the starting position. At this time the pressure switch 35 is still actuated. After the clamping and drilling process, the pressure switch 35 is released and the compressed air supply for the compressed air line 27 is interrupted. The clamping and drilling unit 1 moves into the starting position shown in FIG. 6. Pressure is now applied on the line 37, the feed via the OR valve 38 the drilling machine 16 is pressurized. The drill 16 with the drill 17 is axially extended and the drill 17 is positioned next to it Processing point 13 can take place. This is obtained via a control line 39 Pulse valve 40 the signal, the connection to the compressed air line 26 again to manufacture. The clamping and drilling unit is for making a new borehole 1 now ready to start. This process then runs as described Working conditions in the figures 6 to 9 from.

Description
Aus US-A-3 060 769 ist eine Bohrvorrichtung bekannt, die automatisch mit einer vorbestimmten Vorschubkraft das Bohren ausführen kann. Das Klemmen des Bauteils erfolgt mittels Handkraft, wobei eine Klemmbacke in Klemmrichtung bewegt werden kann. Eine an einer Basiseinheit angeordnete Bohrmaschine wird mittels eines Hebels und eines Federelementes entgegen der Vorschubrichtung vorgespannt. Die damit erzielte Vorschubkraft ermöglicht nach dem Einschalten der elektrischen Bohrmaschine einen automatischen Vorschub zum Bohren des Bohrloches. Mit dieser Lösung kann jedoch nicht ein völlig automatischer Ablauf des Klemmens und Bohrens ohne manuelle Tätigkeit erzielt werden.

- das Funktionsprinzip einer mobilen Klemm- und Bohreinheit,
- in Fig. 2
- die Klemm- und Bohreinheit in einer ersten Ausführungsform in Startposition,
- in Fig. 3
- die Klemm- und Bohreinheit gemäß Fig. 2 in Arbeitsposition,
- in Fig. 4
- die Klemm- und Bohreinheit der ersten Ausführungsform mit rückfederbarem Bohrteil,
- in Fig. 5
- die Klemm- und Bohreinheit in einer zweiten Ausführungsform und
- in Fign. 6 bis 9
- das Funktionsprinzip der Klemm- und Bohreinheit der zweiten Ausführungsform in vier Arbeitspositionen eines Bohrzyklusses.
Aus der Fig. 1 ist das Funktionsprinzip dieser Klemm- und Bohreinheit 1 ersichtlich. Die Klemm- und Bohreinheit 1 weist ein Klemmteil 2 und ein Bohrteil 15 auf. Das Klemmteil 2 und das Bohrteil 15 sind auf einem gemeinsamen Grundkörper 6 angeordnet. Das Klemmteil 2 besteht im wesentlichen aus einem Klemmbügel 3, der von einem vorzugsweise pneumatisch betriebenen Klemmzylinder 4 in die Klemmposition bzw. in die offene Startposition bewegbar ist.
Der Klemmzylinder 4 ist im Bereich der Längsführungen 11 und 12 ebenfalls auf dem Grundkörper 6 angeordnet und mit seiner Kolbenstange zumindest mit einem Rohrelement 7 oder 10 verbunden. Damit kann der Klemmbügel 3 in die Klemmposition oder in die offene Startposition bewegt werden. Das Bohrteil 15, welches im wesentlichen aus einer pneumatischen Bohrmaschine 16 mit Bohrer 17, einem Vorschubzylinder 18 und einer Dämpfungseinrichtung 19 besteht, ist am unteren Bereich des Grundkörpers 6 vorgesehen. Die Bohrerachse 17A des Bohrers 17 verläuft parallel zu den Längsführungen 11 und 12, sodaß mit dem Klemmbügel 3 in Verbindung mit der Klemmhülse 5 die Bauteile an der Bohrstelle präzise zusammengedrückt werden. Die Bohrmaschine 16, der Vorschubzylinder 18 und der pneumatische Dämpfer 19 sind miteinander gekoppelt. Damit wird eine definierte Vorschubbewegung der Bohrmaschine 16 mit dem Bohrer 17 erreicht, die eine nahezu gratfreie Bohrung ermöglicht. Weiterhin ist eine Klemmkraft von ca. 40-60 daN zwischen Klemmhülse 5 und Klemmelement 9 aufzubringen, um Grat bzw. Späne zwischen den Fügeflächen zu verhindern. Die erforderliche Klemmkraft muß größer als die Schnittkraft des Bohrers 17 sowie die zum spaltfreien Zusammendrücken der Bauteile erforderlichen Kraft sein.
Die Anordnung der grundlegenden Bauteile, wie Klemmteil 2 und Bohrteil 16 ist im wesentlichen wie in der ersten Ausführungsform der Klemm- und Bohreinheit 1 realisiert. Aufgrund der komplexeren Steuerung, die für den automatischen Ablauf des Klemm- und Bohrvorganges bei freiliegendem Bohrer notwendig ist, sind unter anderem zusätzlich ein Impulsventil 40, ein Oder-Ventil 38, ein Sperrventil 43 am Vorschubende der Bohrmaschine 16 und dazugehörige Druckluft- bzw. Steuerleitungen an der Klemm- und Bohreinheit 1 vorzusehen.
