Abstract

The tool consists of a base body (8) with two opposite facing holding fixtures (2) in which two tool cassettes (1) with the tool blades (7) are held. The cassettes are fixed by fixing bolts (4) in threaded bores (6) in the base body. Adjustment bolts (3) in additional threaded bores (5) in the base body allow the axially and radially adjustment of the tool cassettes by a taper on one end of the bolts. This adjusts the tools cassettes by a slope at the back of the them. Guiding rails (9) at the front of the tool guide the it in the bore pre-formed by the tool cassette.

Description

Ausbohr- und Reibwerkzeuge, auch einstellbare, sind in vielfältiger Art bekannt. Die bekannten Systeme verfügen aber entweder nur über eine Schneide, oder bei zwei Schneiden sind sie nicht einstellbar. Zudem muß das Schneidwerkzeug über eine Spannpratze gehalten werden, was den Spanabfluß behindert, zum Spänestau und zu unsauberen Schnittbildern führen kann.Boring and reaming tools, also adjustable, are known in many different ways. The known systems either have only one cutting edge, or two They are not adjustable for cutting. In addition, the cutting tool must have a Clamping claw are held, which hinders the chip drain, for chip accumulation and too can lead to dirty cut images.

Der Erfindung liegt die Aufgabe zugrunde, ein Ausbohrwerkzeug zu entwickeln, daß über zwei einstellbare Schneiden verfügt, die einen sauberen Spanabfluß garantieren. Zwei Schneiden erzeugen eine bessere Oberfläche, die Spankräfte am Werkzeug neutralisieren sich und die Standzeiten werden verlängert, da sich der Verschleiß auf zwei Schneiden verteilt.The invention has for its object to develop a boring tool that has two adjustable cutting edges that clean the chip discharge to guarantee. Two cutting edges create a better surface, the chip forces on the Tool neutralize and the tool life is extended because the Wear distributed over two cutting edges.

Diese Aufgabe wird dadurch gelöst, daß zwei Werkzeugkassetten, auf denen die Schneidwerkzeuge angebracht sind, in zwei Schächten auf zwei Ebenen eingestellt und fixiert werden können.This object is achieved in that two tool cartridges on which the Cutting tools are attached, set in two shafts on two levels and can be fixed.

Für die Erfindung ist von Bedeutung, daß durch diese Art der Werkzeugfixierung im Bereich der Schneiden und des Spanflusses keine störenden Spann- und Verstellelemente angeordnet werden müssen. Ferner ermöglicht die kompakte Einstellung und Fixierung in zwei Schächten die Verwendung von zwei Werkzeugkassetten, was bei einer Fixierung über Spannlaschen aus Platzgründen, besonders bei kleinen Werkzeugen, nicht möglich ist.It is important for the invention that this type of tool fixation in Area of the cutting edges and the chip flow no disturbing clamping and adjustment elements must be arranged. Furthermore, the compact setting and fixation enables in two shafts the use of two tool cartridges, what with a fixation not possible using clamping tabs due to space constraints, especially with small tools is.

Die Erfindung wird anhand von in der Zeichnung dargestellten Ausführungsbeispiel erläutert.The invention is based on the embodiment shown in the drawing explained.

Fig. 1 zeigt eine schematische Darstellung des Werkzeuges in Form einer Explosionszeichnung. Auf den Werkzeugkassetten 1 sind die Schneidwerkzeuge 7 angebracht. Mit den Gewindebohrungen 6 wird mittels der Befestigungsschrauben 4 die Werkzeugkassetten 1 fest mit dem Grundkörper 8 in den Spannschächten 2 verbunden. Die Spannschächte 2 sind so ausgebildet, daß die Werkzeugkassetten 1 mit ihren Spannzungen auf zwei Ebenen übereinander geführt und jeweils von unten oder oben gespannt werden. Zudem sind die Spannschächte so groß bemessen, daß sie axiale Verstellwege der Werkzeugkassetten zulassen. Das gleiche gilt für die Bohrungen 5 der Befestigungsschrauben 4; auch sie haben so viel Spiel zu den Befestigungsschrauben 4, daß sie Einstellwege in axialer und radialer Richtung ermöglichen. Fig. 1 shows a schematic representation of the tool in the form of an exploded view. The cutting tools 7 are attached to the tool cassettes 1 . With the threaded bores 6 , the tool cassettes 1 are firmly connected to the base body 8 in the clamping shafts 2 by means of the fastening screws 4 . The clamping shafts 2 are designed so that the tool cassettes 1 are guided one above the other with their clamping tongues on two levels and are each clamped from below or above. In addition, the clamping chutes are dimensioned so large that they allow axial adjustment paths of the tool cartridges. The same applies to the bores 5 of the fastening screws 4 ; They also have so much play with the fastening screws 4 that they allow adjustment paths in the axial and radial directions.

Die Einstellwege in axialer- und radialer Richtung werden durch die Einstellschrauben 3 realisiert, die kegelig angespitzt sind und mit ihren Kegeln über Gegenschrägen der Kassetten 1 Einstellbewegungen bewirken.The adjustment paths in the axial and radial direction are realized by the adjustment screws 3 , which are tapered and cause adjustment movements with their cones over counter-bevels of the cassettes 1 .

Die Führungsleisten 9 führen das Werkzeug in der durch die Werkzeugkassetten 1 vorgeformten Bohrung. Über den Grundkörper 8 wird das Werkzeug mit der Bearbeitungsmaschine gekoppelt.The guide strips 9 guide the tool in the bore preformed by the tool cassettes 1 . The tool is coupled to the processing machine via the base body 8 .
