Abstract

A chuck for a hammer drill consists of an inner member with a parallel bore to receive the shank of the drill. The bore of this inner member extends for about half the length, and a degree of resilience is provided by a transverse slot. The outer surface of a the inner member is tapered to fit in the taper bore of the outer member. The hammer blows exerted by the drill increases the tightness of the fit between inner and outer member. The chuck can be released by driving a wedge through a transverse slot in the outer member.

Das Anwendungegebiet : Bei Schlagbohrmaschinen zur Aufnahme von Steinbohrern.The area of application: For impact drills to take masonry drills.

Die Darstellung ; Die Aufgabe er Erfindung ist es zylindrige Bohrer Fig.3 in einen Aulnahmeschaft Fig. 1 mit Innenkegel (4) einzu-Betzen. Fig. 4 @er Aufnahmemechanismus Fig. 2 besteht aus einem konischen Metallstück, das für dei Sohreraufnahme an der breiten Beite (1) eingebshrt ist (2).The representation ; The object of the invention is cylindrical drills Fig. 3 to be inserted into a receiving shaft Fig. 1 with an inner cone (4). Fig. 4 @er Recording mechanism Fig. 2 consists of a conical piece of metal, which is for dei Sohreraufnahme on the wide side (1) is inserted (2).

In der @ünge der Bohrung (2) ist das Metalstück eingesgt (3).In the length of the hole (2) the metal piece is sunk (3).

Ber Bohrer Fig. 3 wird in die Bohrung (2) des Aufnahmemechanismus Fig. 2 eingefügt Fig.4.About drill Fig. 3 is in the hole (2) of the receiving mechanism Fig. 2 inserted Fig.4.

Der 'ufnahmemechanismus Ligj.2 mit dem eingefügten Bohrer Fig. 4 werden zusammen in den Innenkegel (4) des Aufnahmeschafts Fig. 1 eingefügt Fig. 5.The 'ufnahmemechanismus Ligj.2 with the inserted drill Fig. 4 will be inserted together in the inner cone (4) of the receiving shaft Fig. 1 Fig. 5.

Beim antreiben der Fig.5 druch eine Schlagbohrmaschine wird der Bohrer Fig.3 mit der Schlagbohrmaschine durch den Aufnahmemechanismus Fig.2 über den Aufnahmeschaft Fig. 1 durch den Arbeistsdruck verbunden.When driving the Fig.5 thru a hammer drill the drill Fig.3 with the hammer drill connected by the receiving mechanism Fig.2 via the receiving shaft Fig. 1 by the working pressure.

Das trennen der Fig. 5 geschieht durch einen Austreibekeil Fig.6 Vorteile der erfindung gegenüber dem Stand der Technik : Das Gewicht der Bohrerafufnahme Fig. 5 ist gegenüber Spannbohrfutter geringer.The separation of Fig. 5 is done by a drive wedge Fig.6 advantages of the invention compared to the prior art: The weight of the drill holder Fig. 5 is less compared to the chuck.

Die BohrerFig 4 lassen sich schneller und einfacher wechseln.The BohrerFig 4 can be changed faster and easier.

Die Bohreraufnabme Fig. 5 ist unanfällig gegne Staub, und braucht nicht gewartet werden.The Bohreraufnabme Fig. 5 is not susceptible to dust, and needs not to be serviced.

Zerstörung der Bohrersufnahme Fig.5 durch die Bohrechläge ist auageschlossen.Destruction of the drill holder Fig. 5 due to the drilling impact is excluded.
