Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Die Erfindung bezieht sich auf Bohrfutter zurii centrischen Festhalten von Bohrern und dergl., bei denen der Schaft des Bohrers oder defgl. sowohl cylindrische, als auch beliebig stark konische Form haben darf.The invention relates to drill chucks zurii centric holding of drills and The like. In which the shaft of the drill or defgl. both cylindrical and arbitrary may have a strongly conical shape.

Fig. ι zeigt das Bohrfutter im Längsschnitt durch die Mittellinie.Fig. Ι shows the chuck in longitudinal section through the center line.

Fig. 2 zeigt den Schnitt x-y nach Fig. i.FIG. 2 shows the section xy according to FIG.

Fig. 3 und 4 zeigen das Bohrfutter in der Ansicht.3 and 4 show the drill chuck in Opinion.

Das Bohrfutter besteht aus dem mit Aufsengewinde versehenen Bohrfuttergehäuse a, auf welchem die beiden Muttern c und C1 aufgeschraubt sind.The chuck consists of the externally threaded chuck housing a on which the two nuts c and C 1 are screwed.

Im Gehäuse α sind zur Aufnahme der Backen entsprechende Nuthen eingearbeitet.Corresponding grooves are incorporated in the housing α to accommodate the jaws.

Die Backen sind in diese Nuthen lose eingelegt und ragen mit ihren Knaggen k aus dem Gehäuse hervor. . . '. .The jaws are loosely inserted into these grooves and protrude with their lugs k from the housing. . . '. .

Die Scheibe d ist an dem Gehäuse α befestigt ■ und verhindert das Herausfallen der Backen.The disk d is attached to the housing α and prevents the jaws from falling out.

. Die Befestigung des Bohrfutters kann durch den Schaffe erfolgen, an dessen Stelle auch eine andere Art der Befestigung, wie z. B. Gewinde und dergl., treten kann.. The attachment of the drill chuck can be done by the sheep, in its place another type of attachment, such as. B. thread and the like. Can occur.

Die Wirkungsweise ist folgende:The mode of action is as follows:

Nach dem Einführen des Bohrers in" den mittleren Hohlraum des Gehäuses α werden die beiden Muttern nach, oben bezw. nach unten geschraubt und drücken' durch ihre konischen Innenflächen gegen die vorstehenden Knaggen k der Backen b. After inserting the drill into "the central cavity of the housing α , the two nuts are screwed upwards and downwards, respectively, and press through their conical inner surfaces against the protruding lugs k of the jaws b."

Hierdurch werden die Backen centrisch nach der Mitte bezw. gegen den eingeschobenen Schaft des Bohrers gedrückt, wodurch dieser centrirt und festgehalten wird.As a result, the jaws are centered BEZW to the middle. against the inserted Shank of the drill pressed, whereby this is centered and held.

Es ist ohne Weiteres klar, dafs sich die Backen in gleicher Weise gegen cylindrische wie gegen konische Schafte legen und dafs die Konicität hierbei. ohne jeden Einflufs ist.It is immediately clear that the cheeks are in the same way towards cylindrical ones as if to lay against conical shafts and that the conicity in doing so. is without any influence.
