Description

Die Erfindung betrifft ein Bohrfutter mit ein einem Futterkörper verschiebbar gehaltenen Futterbacken und mit einer Einrichtung zur Öffnungsangabe der Futterbacken.The invention relates to a drill chuck with a chuck body held chuck jaws and with a device for opening the chuck jaws.

Das Einspannen eines Bohrers in das Bohrfutter gelingt am besten, wenn die Öffnung der Futterbacken etwas größer als der gewählte Bohrer ist. Die Geometrie der Futterbacken läßt ihre eingestellte Öffnung schlecht einschätzen. Dadurch kommt es häufig vor, daß die vorgesehene Öffnung zu klein ist, d. h. in einem zweiten Schritt weiter geöffnet werden muß, oder die Öffnung ist zu groß, wodurch der Bohrer schieflagig zum Einspannen kommen kann, was unbedingt vermieden werden muß, da sonst eine Gefahr für die Bedienungsperson besteht.The best way to clamp a drill in the drill chuck is to if the opening of the chuck jaws is slightly larger than the selected one Is drill. The geometry of the chuck jaws leaves their set Badly assess opening. As a result, it often happens that the intended opening is too small, d. H. in a second step must be opened, or the opening is too large, causing the Drill can be skewed to clamp, which is absolutely avoided must be done, otherwise there is a risk for the operator.

Aus der DE-AS 23 47 364 ist bereits ein Bohrfutter bekannt, bei dem die Öffnung der Futterbacken über eine Markierung an der Außenseite eines mit der Spannhülse verschieblichen Gleitsteins und eine gegenüberliegende Skala auf dem Futterkörper abgelesen werden kann. Das Ablesen ist hier nur in einer bestimmten Drehlage und an dem der Einspannöffnung entgegengesetzten Ende des Bohrfutters möglich. Darüber hinaus ist als zusätzliches Bauteil ein Gleitstein erforderlich, und es sind zusätzliche Bearbeitungsvorgänge an der Spannhülse und am Futterkörper notwendig.A drill chuck is already known from DE-AS 23 47 364, where the opening of the chuck jaws is marked the outside of a sliding block that can be moved with the adapter sleeve and read an opposite scale on the chuck body can be. The reading here is only in a certain one Rotational position and at the opposite of the clamping opening End of the chuck possible. It is also an additional Component requires a sliding block, and there are additional machining operations on the adapter sleeve and necessary on the chuck body.

Der Erfindung liegt daher die Aufgabe zugrunde, ein Bohrfutter der eingangs genannten Art anzugeben, bei dem das Ablesen der Öffnung der Futterbacken am vorderen Ende des Bohrfutters und in jeder Drehlage möglich ist, ohne daß zusätzliche Bauteile notwendig sind.The invention is therefore based on the object of a drill chuck of the type mentioned Specify the type in which the reading of the opening of the chuck jaws on front end of the chuck and in any rotational position is possible without that additional components are necessary.

Erfindungsgemäß wird dies dadurch erreicht, daß die Futterbacken (2) des Bohrfutters, siehe Abb. 1 und Abb. 2, auf ihren nach außen liegenden Seiten Skalen (3) mit zugeordneten Zahlenangaben 1, 2, 3, usf. (4) besitzen, wobei sich beim Öffnen der Futterbacken (2) die Skalen (3) in den Futterkörper (1) hineinschieben und so an der vorderen Kante des Futterkörpers (1) an ihr zuvorliegenden Skalenteilen die Futterbackenöffnung abzulesen ist.According to the invention, this is achieved in that the chuck jaws ( 2 ) of the drill chuck, see Fig. 1 and Fig. 2, have scales ( 3 ) with assigned numerals 1, 2, 3, etc. ( 4 ) on their outer sides, wherein when the chuck jaws ( 2 ) are opened, the scales ( 3 ) slide into the chuck body ( 1 ) and the chuck opening can be read on the front edge of the chuck body ( 1 ) on the scale parts lying in front of them.
