Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Die Erfindung betrifft ein mit zwei Klemmbacken versehenes Bohrfutter und besteht im wesentlichen darin, daß die Klemmbacken unter dem Einfluß einer parallel zur Bewegungsrichtung der Klemmbacken gelagerten, mit Schneckengewinde versehenen, drehbaren Scheibe stehen. Hierdurch wird einerseits erreicht, daß der Bohrer an seinem oberen Ende nicht zerfressen wird, und andererseits, daß ίο der zur, Bewegung der Klemmbacken dienende Schlüssel senkrecht zu deren Bewegungsrichtung liegt, so daß er von beliebiger Ausbildung oder Größe sein kann, ohne die Bewegungsfreiheit der Klemmbacken zu stören.
Die Zeichnung stellt ein Ausführungsbeispiel der Erfindung dar, und zwar istThe invention relates to a drill chuck provided with two clamping jaws and consists essentially in the fact that the clamping jaws are under the influence of a rotatable disk which is mounted parallel to the direction of movement of the clamping jaws and is provided with a worm thread. This ensures on the one hand that the drill bit is not eaten away at its upper end, and on the other hand that the key used to move the clamping jaws is perpendicular to their direction of movement, so that it can be of any design or size without the freedom of movement of the To disturb clamping jaws.
The drawing represents an embodiment of the invention, namely is

Fig. 4 eine Ansicht der Klemmbacken,Fig. 3 is a bottom view,
4 shows a view of the clamping jaws,

Fig. 5 eine Ansicht der mit Schneckengewinde versehenen Scheibe.Fig. 5 is a view of the worm-threaded disk.

In dem Gehäuse 1 des Bohrfutters sind die beiden Klemmbacken 2 gelagert, von denen jede an ihrer Außenseite mit einem Teil eines Schneckengewindes 3 versehen ist. Diese beiden Gewindeteile sind so zu einander angeordnet, daß sie beide gleichzeitig von einem Schneckengewinde 4 beeinflußt werden, das auf einer in dem Gehäuse 1 gelagerten, mittels eines Vierkantschlüssels 9 drehbaren Scheibe 5 angeordnet ist. Die Spannweite der Klemmbacken ist begrenzt durch die Öffnung 6 des Gehäusedeckels 7, durch welche die Klemmbacken mit Ansätzen 8 greifen.In the housing 1 of the drill chuck, the two clamping jaws 2 are mounted, of which each is provided with a part of a worm thread 3 on its outside. These two Threaded parts are arranged to each other that they both of a worm thread at the same time 4 can be influenced, the one stored in the housing 1, by means of a square wrench 9 rotatable disc 5 is arranged. The span of the clamping jaws is limited by the opening 6 in the housing cover 7, through which the jaws with lugs 8 grip.
