Vom Boden 8 her erstreckt sich eine im Durchmesser grössere Bohrung 10 bis in den Bereich der Gegenwand des Bodens 8 zum Gehäuse 3, wobei von aussen ein 5 entsprechender Seitenkanal 11 in die Bohrung 10 mündet, wie dies aus Fig. 2 ersichtlich ist. In der dem Boden 8 gegenüberliegenden Gehäusewand ist ein Kugellager 13 eingepresst. Eine Antriebswelle 14 mit einem Bund 15 und einem Zahnriemenritzel 16 ist mit einem weiteren Bund 17 und einem Wellenende 18 versehen (Fig. 2) . Diese Antriebswelle 14 wird in die Bohrung 10 und das Kugellager 13 eingeführt und steht in montiertem Zustand, wie in Fig. 2 strichpunktiert angedeutet ist, aus dem Gehäuse 3 vor.

Auf sich gegenüberliegenden Seiten des Tragarmes 27 sind Riemen¬ führungskanäle 35 und 36 vorgesehen, an deren Ende der Tragarm 27 gabelförmig ausgebildet ist und der Aufnahme eines Zahnriemenritzels 37 dient.

On one narrow side of the housing 3, which runs parallel to the bore 10, there is a threaded bore 24 for receiving it of a holding rod 25. A tool support arm 27 with a transversely continuous cutout 28 has a central bore for receiving a tension spring 29, which is designed as a helical spring. Two side screws 30 hold the tension spring 29 in the support arm 27.

A grub screw 43 is used to hold a deburring tool 45, which can thus be replaced in a simple manner. The deburring tool 45 is provided with an actual tool head 46, which is followed by a bearing stub 47 with an end 48 which fits into a ball bearing 38.

Die Montage dieser Vorrichtung erfolgt dergestalt, dass die Antriebswelle 14 durch die Bohrung 10 in das Gehäuse 3 eingeführt wird. Nachdem die Antriebswelle 14 im Kugellager 13 des Gehäuses 3 gelagert ist, wird der Zahnriemen 21 seitlich über das Ritzel 16 ge¬ schoben, so dass er sich längs der Seitenwände des Seitenkanals 11 erstreckt und aus diesem herausragt. Hierauf wird der Deckel 4 so aufgesetzt, dass das Wellenende 18 im Kugellager 20 lagert. Dann wird der Deckel mittels der Schrauben 5 am Gehäuse 3 be¬ festigt. Dann wird der Werkzeug-Tragarm 27, welcher in verschiedenen Längen vorliegt, mit seinen Führungs¬ schienen 31 in die Führungsnuten 33 des Gehäuses 3 eingeschoben, bis die Spannfeder 29 am Haltestift 22 zum Anliegen kommt. Hierauf wird der Tragarm ent- • gegen der Spannfeder 29 nach hinten in das Gehäuse 3 gepresst und der Riemen 21 über das Zahnriemenritzel 37 geschoben. Die Spannfeder 29 versucht nun den Tragarm 27 nach aussen aus dem Gehäuse 3 zu stossen, was der Zahnriemen 21 verhütet, wobei dieser ent¬ sprechend der Spannkraft der Feder 29 gespannt wird.This device is installed in such a way that the drive shaft 14 is inserted into the housing 3 through the bore 10. After the drive shaft 14 is mounted in the ball bearing 13 of the housing 3, the toothed belt 21 is pushed laterally over the pinion 16 so that it extends along the side walls of the side channel 11 and protrudes therefrom. Then the cover 4 is placed so that the shaft end 18 is supported in the ball bearing 20. Then the cover is fastened to the housing 3 by means of the screws 5. Then the tool support arm 27, which is available in different lengths, is inserted with its guide rails 31 into the guide grooves 33 of the housing 3 until the tension spring 29 comes to rest on the retaining pin 22. Then the support arm is pressed against the tension spring 29 backwards into the housing 3 and the belt 21 is pushed over the toothed belt pinion 37. The tension spring 29 now tries to push the support arm 27 outwards from the housing 3, which prevents the toothed belt 21, which is tensioned in accordance with the tensioning force of the spring 29.
_ O PI Zu jedem Tragarm gehört ein Riemen 21 entsprechender Länge._ O PI A strap 21 of corresponding length belongs to each support arm.
Zu jeder Vorrichtung gehört ein Satz von Werkzeug- Tragarmen 27 unterschiedlicher Länge, welche aus¬ tauschbar im Gehäuse 3 befestigt sind. Zum Aus¬ wechseln ist der Deckel 4 wegzuheben, der Riemen 21 gegen den entsprechenden zum neu einzuführenden Tragarm 27 passenden Riemen auszuwechseln, der Deckel wieder aufzubringen und der neue Tragarm, wie er¬ läutert, zuzuschieben. Zum Wechseln des Werkzeuges entsprechend der zu bearbeitenden Bohrung wird die Madensσhraube 43 gelöst, das Entgrater-Werkzeug 45 seitlich herausgezogen und das andere Werkzeug ein- geschoben, so dass beim Anziehen der Madenschraube 43 diese auf die Anfräsung 49 des Lagerstummels 47 trif t und das Werkzeug mit dem Ritzel 37 fest ver¬ bindet.Each device includes a set of tool support arms 27 of different lengths, which are interchangeably fastened in the housing 3. To replace it, the cover 4 has to be lifted away, the belt 21 has to be replaced by the corresponding belt for the new support arm 27 to be inserted, the cover has to be replaced and the new support arm has to be pushed in as explained. To change the tool in accordance with the bore to be machined, the grub screw 43 is loosened, the deburring tool 45 is pulled out to the side and the other tool is pushed in, so that when the grub screw 43 is tightened, it meets the milling 49 of the bearing stub 47 and the tool firmly connected to the pinion 37.
Diese Vorrichtung ist sehr kompakt, äusserst einfach im Aufbau und leicht an die sich in der Praxis er¬ gebenden Probleme bezüglich Durchmesser der Bohrungen, Ort der Bohrungen und dgl. anpassbar. Die Verwendung eines Zahnriemens mit durch eine Spannfeder bestimmte Riemenspannung stellt gleichzeitig eine Ueberlast- sicherung dar, indem der Zahnriemen bezüglich Dimensionen und Material so beschaffen ist, dass bei Ueberschreiten einer vorgesehenen ümfangskraft auf den Riemen dessen Zähne elastisch deformiert werden, wodurch der Antrieb des Zahnritzels 37 mit dem Werk¬ zeug unterbrochen wird. Die kritische ümfangskraft kann durch die Wahl der Spannfeder 29 verändert werden. This device is very compact, extremely simple in construction and easily adaptable to the problems which arise in practice with regard to the diameter of the bores, the location of the bores and the like. The use of a toothed belt with a belt tension determined by a tension spring also represents an overload protection, in that the toothed belt is designed in terms of dimensions and material in such a way that when a predetermined circumferential force on the belt is exceeded, its teeth are elastically deformed, thereby driving the toothed pinion 37 is interrupted with the tool. The critical circumferential force can be changed by the choice of the tension spring 29.
