Description
Gemäß Patent 748 732 werden Mehrkantschneiden mittels an ihrer Außenfläche kegelförmigerBuchsen durchEinpressen in kegelförmige Bohrungen von Wiegehebeln befestigt. Das genaue kegelige Aufreiben dieser Bohrungen erfordert einen gewissen Aufwand von Sonderwerkzeugen. According to patent 748 732 polygonal cutting edges by means of on their outer surface Conical bushes attached by pressing into conical bores of rocker arms. The exact conical reaming of these holes requires a certain amount of effort of special tools.
Bei der nachstehend beschriebenen Erfindung fällt dieser Sonderaufwand fort. In den Zeichnungen ist die Erfindung beispielsweise dargestellt. In the case of the invention described below, this extra expense is eliminated away. The invention is illustrated by way of example in the drawings.
Fig. I zeigt die Ausführung einer Buchse, die eine Mehrkantschneide vollkommen umschließt; Fig. 2 zeigt eine Buchse, die nur den Fuß einer Nfehrkantscbneide umfaßt. Fig. I shows the design of a socket which has a polygonal cutting edge completely encloses; Fig. 2 shows a socket which only has the foot of a Nfehrkantscbneide includes.
Die Mehrkantschneide I bzw. I' sitzt in einer an ihrer Außenfläche kegeligen Buchse 2 bzw. 2'. The polygonal cutting edge I or I 'sits in one on its outer surface conical socket 2 or 2 '.
Diese wiederum wird von einer außen zylindrischen und innen kegeligen geschlitzten Buchse 3 bzw. 3' umfaßt. Die Wiegehebel sind nun mit zylindrischen Bohrungen versehen, die dem Außendurchmesser der zylindrischen Buchse entsprechen. Die Durchmesserverhältnisse sind so gewählt, daß nach dem Zusammenpressen der Buchsen 2 und 3 bzvv. 2' und 3t in axialer Richtung die Mehrkantschneide I bzw. I' in dem Wiegehebel unverrückbar festgepreßt ist.This in turn has a cylindrical outside and a conical inside slotted socket 3 or 3 'includes. The rocker arms are now cylindrical Provide holes that correspond to the outer diameter of the cylindrical socket. The diameter ratios are chosen so that after the bushings have been pressed together 2 and 3 resp. 2 'and 3t in the axial direction the polygonal cutting edge I and I' in the The rocker arm is immovable.
Die Erfindung bezieht sich nicht nur auf Mehrkantschneiden in der gezeichneten Form, sondern auf alle Schneiden mit in der Längsrichtung parallelen Kanten. Es sind dieses beispielsweise Schneiden mit Dreikant-, Vierkant- oder Tropfenprofil sowie Schneiden mit einem an der Klemmstelle runden Querschnitt. The invention relates not only to polygonal cutting edges drawn shape, but on all cutting edges with parallel lines in the longitudinal direction Edge. These are, for example, cutting with a triangular, square or teardrop profile as well as cutting with a round cross-section at the clamping point.
