Abstract

The mechanism consists of a bevel gear arrangement (10,11), part of which is an integral chuck for a hand drill. The chuck has a through hole so as to enable the drill bit (12) to pass through. There is a winding key (6), with projections which fit into blind bores (5) in the chuck clamping portion (4), to clamp or loosen the chuck. This portion screws on to a grip portion (2) which is in contact with the drill bit. This portion engages with tapered portions (1) engaging with a conical portion (7). This runs in bearings (8) at each end. USE/ADVANTAGE - Compact integrated construction of chuck for gripping drill bit.

Description

Die vorliegende Erfindung bezieht sich auf ein Winkelbohr­ getriebe mit voll integriertem Bohr-Spannfutter, welches einen Bohrer-Durchlaß aufweist.The present invention relates to an angle drill gear with fully integrated drill chuck, which has a drill passage.

Das vorbeschriebene Winkel-Bohrgetriebe kann Bestandteil einer Winkel-Handbohrmaschine sein oder als Vorsatzgerät zum Einsatz kommen.The above-described angle drilling gear can be a component an angle hand drill or as an attachment are used.

Dem Stand der Technik entspricht ein Winkelbohrgetriebe mit vorgesetztem oder teilintegriertem Bohr-Spannfutter (meist Zahnkranzfutter).An angular drilling gear corresponds to the state of the art upstream or partially integrated drill chuck (mostly Ring gear lining).

Dieses birgt den Nachteil eines weit ein­ geschränkten Einsatzbereiches als Folge von Aufeinandermaßung von Getriebehöhe + Bohr-Spannfutterlänge + Bohrerlänge.This harbors the disadvantage of one far restricted area of application as a result of overlap of gear height + drill chuck length + drill length.

Erfindungsgemäß werden diese Nachteile dadurch weiter ausge­ schlossen, daß das Bohr-Spannfutter völlig integriert ist und der Bohrerschaft weiter im Futterdurchlaß verschwindet.According to the invention, these disadvantages are further exaggerated concluded that the drill chuck is fully integrated and the drill shaft disappears further in the feed passage.

Die Lösung im Einzelnen gestaltet sich folgendermaßen:The individual solution is as follows:

Das Spannfutter ist im Bereich der Spannbacken (1) auf be­ kannte Weise gestaltet.The chuck is designed in a known manner in the area of the jaws ( 1 ).

Die Spannung des Futters wird jedoch mittels einer Druck­ hülse (2), welche axial auf die konischen Spannbacken (1) wirkt, erreicht. The tension of the chuck is achieved by means of a pressure sleeve ( 2 ), which acts axially on the conical jaws ( 1 ).

Entsprechend durch axialen Zug die Entspannung. Die Druck­ hülse (2) ist einerseits, in bekannter Weise durch Axial­ verhakung (3) mit den Spannbacken (1) verbunden, um so auch die zur Entspannung nötigen Zugkräfte übertragen zu können und ist andererseits mittels eines Außengewindes (2/4) und einer axial fixierten Innengewinde-Hülse (4) axial verschieb­ bar. Die Gewindehülse (4) nimmt auf der nach außen gelegenen Stirnseite die Antriebsklauen, bzw. Zapfenbohrungen (5) für einen Spannschlüssel (6) auf.Correspondingly, relaxation through axial pull. The pressure sleeve ( 2 ) is on the one hand, in a known manner by axial interlocking ( 3 ) with the clamping jaws ( 1 ), so as to be able to transmit the tensile forces necessary for relaxation and on the other hand by means of an external thread ( 2/4 ) and axially fixed internal thread sleeve ( 4 ) axially displaceable. The threaded sleeve ( 4 ) receives the drive claws or pin bores ( 5 ) for a wrench ( 6 ) on the outward end face.

Das zylinderförmige Spannfuttergehäuse (7) wird mittels Wälz­ oder Gleitlagerringen (8) in das Getriebegehäuse (9) einge­ lagert und über einen Außen- oder Tellerzahnkranz (10) auf bekannte Weise durch ein Ritzel (11) angetrieben.The cylindrical chuck housing ( 7 ) is stored in the gear housing ( 9 ) by means of rolling or plain bearing rings ( 8 ) and is driven in a known manner by a pinion ( 11 ) via an external or ring gear ( 10 ).
