Description
Die Erfindung bezieht sich auf einen Senker mit geschlitztem Klemmschaft, der zusammen mit einem Spiralbohrer in einem Aufnahmeteil mit konischer Bohrung festspannbar ist, und bezweckt, Vorkehrungen für die Begrenzung der Wirkungstiefe des Senkers und der Einspanntiefe des geschlitzten Klemmschaftes zu treffen. Zudem Zweck siecht die Erfindung am Umfang des Senkers einem Anschlagring vor, der mit dem Senkerkopf starr verbunden oder darauf axial versrhellbar ilst. Mitteh dieses Anschlages kann nicht nur dü:e Senktieie genau eingestellt werden, sondern auch die Bdhrtiefe, da. beide Werkzeuge in einem Arbeitsgang in Wirkung treten und rder Anschlagring am Senkerkopf die Senktiefe entsprechend der Einsstellung des Bohrers innerhalb des Senkürschäftes bestimmt. Zur Begrenzung-der Einspanntiefe desgeschrlitzten.Klercnmschaftes sieht die Erfindung an letzterem außerdem noch geschlitzte Ringteile in einem Abstande vom Senkerkopf vor, der etwa gleich der doppelten axialen Breite dieser Ringteile isst. Durch diese Bestimmung des Abstandes der Auschlagringtege wird düse Elastizität der Segmente des geschlitzten Schaftres in einen au!sireichendan Abstande von der Bruchgrenze gehalten.The invention relates to a countersink with a slotted clamping shaft, together with a twist drill in a receiving part with a conical bore can be clamped, and the purpose is to make provisions for limiting the depth of action of the countersink and the clamping depth of the slotted clamping shaft. In addition Purpose of the invention seeks a stop ring on the circumference of the countersink, which with rigidly connected to the countersunk head or axially adjustable on it. Mitteh this Not only can the lowering be adjusted precisely, but also the depth, there. both tools come into effect in one operation and rder The stop ring on the countersunk head adjusts the countersink depth according to the setting of the drill determined within the cut business. To limit the clamping depth of the slotted clergy the invention also sees slotted ring parts at a distance from the latter from the countersunk head, which is approximately equal to twice the axial width of these ring parts eats. This determination of the distance between the knock-out ring webs results in elasticity the segments of the slotted shaft at a sufficient distance from the Breaking point held.
Ein AusfühTungsbeiispiel ist in. der Zeichnung in Ansicht dargestellt.An embodiment is shown in the drawing in a view.
Um beim Ansenken eines Bohrloches eine möglichst großeGenauigkeit in der Senktiefe zu erzielen, ist am Umfang des Senkers ein Ring h vorgesehen, der aufgeschrumpft oder auch verstellbar sein kann. An dem zum Festspannen des Bohrers geschlitzten Scheft des Senkens ist ein geschlitzter Anschlagring g in einem Abstande vom Senkerkopf gleich etwa der doppelten Breite dies getschlitzten Anschlagringes vorgesehen. Die Schlütze des Anaschlagringes g decken stich mit den Schlitzen .des Schaffiles des Senkers. Dieser Ring g begrenzt die Einspanntiefe und verhindert .eine Überbeanspruchung der Schafüstgmente.In order to achieve the greatest possible accuracy when countersinking a borehole to achieve in the countersink, a ring h is provided on the circumference of the countersink, the can be shrunk on or adjustable. On the one for clamping the drill slotted shank of the lowering is a slotted stop ring g at a distance from the countersunk head equal to about twice the width of this slotted stop ring intended. The catches of the stop ring g cover stich with the slots .des Sheep files of the sinker. This ring g limits the clamping depth and prevents .an overuse of the sheep components.
