Description

Dias Bohren von Löchern, die je etwa zur Hälfte in Werkstücken aus verschiedenenSlides drilling holes that are about to be used Half in work pieces from different

: Werkstoffen sitzen, z.B. in ein Gehäuse aus Stahl und eine eingesetzte Buchse aus Gußeisen bietet ohne Verwendung einer Führung für den Bohrer Schwierigkeiten. Der Bohrer findet im weicheren Werkstoff weniger Widerstand und verläuft. Da die eingesetzten Büchsen nicht immer die gleiche Wandstärke : Sitting materials, for example in a housing made of steel and an inserted socket made of cast iron presents difficulties without using a guide for the drill. The drill finds less resistance in the softer material and runs. Because the bushings used do not always have the same wall thickness

ίο haben, die Durchmesser der Büchsen oft auch verschieden sind und die zu bohrenden Löcher nicht immer gleich groß sind, müssen jeweils besondere Vorrichtungen hergestellt werden, was recht kostspielig ist.ίο often have the diameter of the bushings too are different and the holes to be drilled are not always the same size special devices are made each time, which is quite expensive.

Um diese Mängel zu beseitigen, kann die neue .Vorrichtung mit bekannten Mitteln in verschieden großen Aufnahmebohrungen genau mittig festgespannt werden, und ferner trägt sie gruppenweise auf Spirallinien an-To eliminate these deficiencies, the new .Vorrichtung can by known means in different sized mounting holes are clamped exactly in the middle, and further wear them in groups on spiral lines

21) geordnet Bohrbüchsen, die in jeder Gruppe wohl denselben Durchmesser haben, aber verschiedene radiale Abstände von der Mitte der Aufnahmebohrung besitzen.21) arranged drill sleeves in each group probably have the same diameter, but different radial distances from the center own the mounting hole.

In Abb. ι ist die neue Vorrichtung imIn Fig. Ι the new device is in

J.5 Schnitt gemäß der Linie A-B in Abb. 2 dargestellt. Abb. 2 zeigt die Draufsicht.J.5 Section along the line AB shown in Fig. 2. Fig. 2 shows the top view.

Auf dem Bolzen ι sind die mit radialen bzw. spiralförmigen Schlitzen versehenen Scheiben 2 und 3 angebracht. Zwischen diesen Scheiben sind drei Druckstücke 4 angeordnet, die beim Drehen der Scheibe 2 und gleichzeitigen Festhalten der Scheibe 3 nach außen verschoben werden und die Vorrichtung in verschieden großen Aufnahmebohrungen genau mittig festspannen. Die Bohrplatte 5 ist nach dem Festspannen der Vorrichtung in der Aufnahmebohrung noch frei drehbar und kann durch eine Kordelmutter 6 in verschiedenen Stellungen festgespannt werden.The disks provided with radial or spiral slots are on the bolt ι 2 and 3 attached. Three pressure pieces 4 are arranged between these discs, when rotating the disc 2 and at the same time holding the disc 3 outwards are moved and the device in different sized mounting holes exactly clamp in the middle. The drilling plate 5 is after clamping the device in the mounting hole is still freely rotatable and can be adjusted by a cord nut 6 in different Positions are clamped.

^0 Dadurch, daß in der Bohrplatte 5 verschieden große Bohrbüchsen in Spirallinien angeordnet sind, ist es möglich, verschieden große Löcher in verschiedenen radialen Abständen von der Mitte der Aufnahmebohrung zu bohren. Man ist also hierbei von der Wandstärke der zu verbohrenden Buchse unabhängig. ^ 0 The fact that 5 different sized drill sleeves are arranged in spiral lines in the drill plate, it is possible to drill holes of different sizes in different radial distances from the center of the receiving bore. So you are independent of the wall thickness of the socket to be drilled.

Die Befestigungsart der Vorrichtung in der Aiifnahmebohrung sowie das Anordnen von verschiedenen Bohrbüchsen in einer gegenüber der Spannvorrichtung drehbaren Scheibe sind fachbekannt. Die bekannten Vorrichtungen sind aber durch ihren Aufbau zu dem oben angegebenen Zweck wenig ge^ eignet und haben meist den Mangel, daß die verwendeten Schieber, Gewindespindeln, Skalen u. dgl. durch Bohrspäne verunreinigt und verstopft werden können.The type of fastening of the device in the receiving bore and the arrangement of different drill sleeves in one rotatable with respect to the clamping device Disc are known in the art. The known devices are due to their structure little used for the purpose given above suitable and usually have the defect that the slides, threaded spindles, Scales and the like can be contaminated and clogged by drilling chips.

Weiterhin bekannte Vorrichtungen, die den Zweck haben, in Gehäuse eingesetzte Büchsen zu verbohren, haben den Nachteil, daß sie nicht unbedingt mittig spannen und" von einer gleichen Wandstärke der eingesetzten Buchse abhängig sind. Auch hierbei können die verwendeten Gewindespindern leicht verunreinigt werden.Furthermore, known devices which have the purpose of being inserted into housings cans to drill, have the disadvantage that they do not necessarily clamp in the middle and "from the same wall thickness of the socket used are dependent. Here too you can the threaded spindles used are easily contaminated.

Die vorbeschriebenen bekannten Einzelheiten sind beim Aufbau der neuen Vorrichtung sinngemäß verwertet worden und vermitteln durch ihre Gesamtvereinigung und durch die spirallinige Anordnung der Bohrbüchsen die eingangs beschriebenen Vorteile. The known details described above are in the construction of the new device have been appropriately utilized and convey through their overall association and through the spiral arrangement of the drill sleeves the advantages described above.
