Description
Das Bearbeiten von Auflageflächen für Muttern u. dgl., z. B. an Flanschen, welche mit einem normalen Senkwerkzeug wegen der ausladenden Form nicht direkt zugänglich sind,. geschieht hauptsächlich in der Weise, daß ei.ne.entsprechende Spindel durch das Bohrloch durchgeführt und dann in den vorgesehenen Schlitz dieser Spindel ein zweiseitiges Messer gesteckt und durch Keile oder Schrauben festgehalten wird. Außerdem sind Senkwerkzeuge bekannt, bei denen innerhalb einer Spindel gelagerte Messer von außen her über ein in der hohl ausgebildeten Spindel liegendes Betätigungsgestänge in Arbeitsstellung gebracht, festgehalten und zurückgezogen werden können.The processing of bearing surfaces for nuts and the like. B. on flanges, which are not directly accessible with a normal countersinking tool because of the sweeping shape are,. happens mainly in such a way that a corresponding spindle is carried out the borehole is carried out and then inserted into the slot provided on this spindle double-sided knife is inserted and held in place with wedges or screws. aside from that countersinking tools are known in which knives of outside via an actuating rod located in the hollow spindle can be brought into working position, held in place and withdrawn.
Bei einem Werkzeug dieser Art ist nach der Erfindung das Schneidmesser irr einem Schlitz der Hohlspindel geführt und um einen in einem Langloch der Verstellspindel beweglichen Zapfen in die Umgrenzung der Hohlspindel hineinschwenkbar, deren in das Werkstück einzuführendes, über den Schlitz hinausragendes Ende verschlossen ist . und ,als' Widerlager für das Schneidmesser in der Arbeitsstellung dient. Die für das Ausbringen des Messers erforderliche Raumhöhe am Werkstück ist bei dem neuen, in seinem Aufbau einfachen Werkzeug nicht großer als z. B. eine-normale Mutterhöhe, so daß es auch bei beschränkten Raumverhältnissen angewendet werden kann.In a tool of this type, the cutting knife is according to the invention guided in a slot in the hollow spindle and around one in an elongated hole in the adjusting spindle movable pin can be swiveled into the boundary of the hollow spindle, whose in the workpiece to be introduced, the end protruding beyond the slot closed is . and 'as' an abutment for the cutting knife in the working position. the The required room height on the workpiece for removing the knife is for the new, simple tool in its structure not larger than z. B. a-normal nut height, so that it can also be used in confined spaces.
In den beiden Schnittzeichnungen ist ein Ausführungsbeispiel des Erfindungsgegenstandes dargestellt.An exemplary embodiment of the subject matter of the invention is shown in the two sectional drawings shown.
In der Hohlspindel z@, deren Außendurchmesser dem Bohrloch entspricht, wird etwa durch eine Ringmutter 2 eine Innenspindel 3 bewegt, an deren unterem geschlitzten Ende das Messer 4 in einem Langloch mit-dem Stift 5 eingehängt ist. Wird die Innenspindel äbwärts-bewegt,- so -wird das Messer infolge seiner gerundeten Form aus dem Schlitz 6, in dem es gleichzeitig geführt ist, herausgeschoben und durch Anziehen der Ringmutter festgehalten. Beim Lösen der Mutter bewegt sich die Innenspindel wieder nach oben, das Messer legt sich beim Ausfahren der Bohrspindel aus dem Bohrloch in dieselbe hinein. Durch Anhalten der Ringmutter mit der Hand während des Links- bzw. Rechtslaufes der Antriebsmaschine kann in kürzester Zeit das Messer ein- und ausgefahren werden. Zweckmäßigerweise wird die Ringmutter mit Linksgewinde versehen, wodurch bei dem üblichen Rechtslauf der Antriebsmaschine das Ausbringen des Messers in Arbeitsstellung und anschließend das Bearbeiten der Auflageflächen ohne Abstellen der Maschine vorgenommen werden kann.In the hollow spindle z @, the outer diameter of which corresponds to the borehole, an inner spindle 3 is moved, for example by an annular nut 2, at the lower slotted end of which the knife 4 is suspended in an elongated hole with the pin 5. If the inner spindle is moved downwards, - as a result of its rounded shape - the knife is pushed out of the slot 6, in which it is guided at the same time, and is held in place by tightening the ring nut. When the nut is loosened, the inner spindle moves upwards again, and the knife is inserted into the drill spindle when it is extended out of the borehole. By holding the ring nut with your hand while the drive machine is running to the left or right, the knife can be retracted and extended in a very short time. The ring nut is expediently provided with a left-hand thread, so that with the normal clockwise rotation of the drive machine, the knife can be brought out into the working position and then the support surfaces can be machined without having to turn off the machine.
