Description
Bohrfutter, bei denen durch den achsial gerichteten Bohrdruck die Klemmbacken in
einen Hohlkegel des Futterkörpers gepreßt werden, sind bekannt. Bei den bekannten
· Bohrfuttern dieser Art sind die Klemmbacken durch eine eingelegte Scheibe miteinander verbunden,
gegen die sich der Bohrer legt. Demgegenüber besteht die Erfindung darin, daß
statt dieser Scheibe ein den Bohrdruck aufnehmender Ansatz der einen Backe die anderen
Backen mitnimmt.
Auf der Zeichnung zeigen
Abb. ι einen Längsschnitt dur.ch das Bohrfutter und die
Abb. 2, 3 Einzelheiten.Drill chucks in which the clamping jaws are pressed into a hollow cone of the chuck body by the axially directed drilling pressure are known. In the known drill chucks of this type, the clamping jaws are connected to one another by an inserted disk against which the drill rests. In contrast, the invention consists in that, instead of this disk, a shoulder of one jaw that absorbs the drilling pressure takes the other jaws with it.
Show on the drawing
Fig. Ι a longitudinal section through the drill chuck and the
Fig. 2, 3 details.
Der Futterkörper K nimmt in seinem Innern · drei oder mehr Klemmbacken auf, die durch die Überwurfmutter M in bekannter Weise gegen ein Herausfallen gesichert sind: Klemmbacke A besitzt am oberen Teile einen Flansch mit , mehreren Schlitzen s zur Befestigung und Führung der anderen Klemmbacken B. Der Bohrerschaft drückt nun unter die Klemmbacke A und drückt sie nach oben; zur gleichen Zeit werden die Backen B mitgenommen, welche durch die Führungs- und Befestigungsschraube C mit der Klemmbacke A verbunden sind. Auf diese Weise wird der Bohrer zentriert und beim Arbeiten immer fester gespannt, weil die Klemmbacken B gleichmäßig mit der Klemmbacke A in den Hohlkegel des Futterkörpers gepreßt werden.The chuck body K takes in its interior · three or more clamping jaws which are secured by the nut M in a known manner against falling out: jaw A has a flange at the upper parts, a plurality of slots s for mounting and guiding the other jaws B. The drill shaft now presses under the clamping jaw A and presses it upwards; At the same time, the jaws B , which are connected to the clamping jaw A by the guide and fastening screw C, are taken along. In this way, the drill is centered and tightened as you work, because the jaws B are pressed evenly with the jaw A into the hollow cone of the chuck body.
