  Mit Klemmschlitz und Zylindrischer, zweckmässig exzentrischer Bohrung versehene
Klemmhülse für Dreh- oder Bohrerstähle. 



   Für im Querschnitt runde   DreÍ1stählo   gibt es eine handliche, im Gebrauch bestens bewährte Einspannvorrichtung, welche darin besteht, dass eine Hülse 1, mit vielen Fassetten 2 versehen, eine exzentrische durchgehende Bohrung. 9 zur Einführung des Rundstahles besitzt, von welcher Bohrung tangential ein Klemmschlitz 4 nach aussen führt. Beim Festschrauben dieser Hülse 1 in irgend einer Lage des Schlitzes 4 verengt sich dieser federnd über dem eingeführten Rundstahl und hält diesen unverrückbar fest. Exzentrisch ist die Bohrung 3 deshalb,   um-innerhalb gewisser Gren/en-dem Drehstahl die gewünschte   Höhe zur Einstellung des Schneidewiukels geben zu können. Ein   oder mehrere schmälm   Schlitze 5 im Diekfleisch der Hülse 1 begünstigen die Federung. 



   Dieser Werkzeughalter, welcher sich für   Rundstähle   im Gebrauch bestens bewährte, hat den einen grossen Nachteil, dass er eben nur für Stähle mit rundem Schaft und bestimmtem Durchmesser verwendbar ist. 



   Gegenstand vorliegender Erfindung ist eine, wie bisher der Rundstahl in die Hülse 1 einzuführende, also aussen gleichfalls zylindrische   K) emmhü ! se   6 mit Klemmschlitz 7,   welche   eine entweder zentrale oder gleichfalls exzentrische Bohrung 8 enthält, deren Querschnitt dem des einzuspannenden kantigen   Dreh-oder Bohrstahles,   also entweder quadratischen, rechteckigen, ja sogar drei-oder vieleckigen Querschnitt besitzt.

   Beim   Zuklemmen der   äusseren Hülse 1 wird auch die innere Klemmhülge 6 federnd verengt und das Werkzeug (Drehstahl, Hobelstahl oder Bohrer usw.)   festgoMclH.   Diese innere Klemmhülse 6 gewährloistet noch den weiteren Vorteil, dass man auch Stähle schwächerer Querschnittshöhe einspannen kann, wenn man eine oder mehrere   Hpiltgen   einschiebt. So kann z. B. auch ein Quadratstahl in einer   Klemmhülse   6 mit rechteckiger Öffnung unter Einschiebung von Beilagen eingespannt werden. 

**WARNUNG** Ende DESC Feld kannt Anfang CLMS uberlappen**.

  With a clamping slot and a cylindrical, appropriately eccentric bore
Clamping sleeve for turning or drilling steels.



   For DreÍ1stählo round in cross-section there is a handy, well-proven clamping device, which consists in that a sleeve 1, provided with many facets 2, an eccentric through hole. 9 has to introduce the round steel, from which bore a clamping slot 4 leads tangentially to the outside. When this sleeve 1 is screwed tight in any position of the slot 4, it narrows resiliently over the inserted round steel and holds it immovably. The bore 3 is therefore eccentric in order - within certain limits - to be able to give the lathe tool the desired height for setting the cutting edge. One or more narrow slots 5 in the meat of the sleeve 1 favor the suspension.



   This tool holder, which has proven itself in use for round steels, has the one major disadvantage that it can only be used for steels with a round shaft and a certain diameter.



   The subject matter of the present invention is a K) emmhü, which is to be introduced into the sleeve 1 as previously the round steel, that is to say likewise cylindrical on the outside! se 6 with clamping slot 7, which contains an either central or also eccentric bore 8, the cross-section of which has that of the angular turning or drilling steel to be clamped, ie either square, rectangular, even triangular or polygonal cross-section.

   When the outer sleeve 1 is clamped shut, the inner clamping sleeve 6 is also resiliently narrowed and the tool (turning tool, planing steel or drill, etc.) is fixed. This inner clamping sleeve 6 also guarantees the further advantage that steels with a weaker cross-sectional height can also be clamped if one or more Hpiltgen is inserted. So z. B. can also be clamped a square steel in a clamping sleeve 6 with a rectangular opening with the insertion of inserts.
