Abstract

The bell-shaped tool is for drilling and turning during turbine housing production. A cross-slide (7) carries the tool and is driven by and advancing gear through the main spindle. An additional tool carrier (5) is coupled to the front of the drill bell (1) via a cross beam (2). This has a tapering diameter leading into the cross-slide. The advance gear (4) is driven through the central borehole of the drill bell. Selectively operable couplings (9) are used to effect advancing movement of the cross-slide and tool slide. This cross-slide avoids the need to replace the head of the drill bell or the bell itself when chaning from machining large to smaller diameters.

Description

Werkzeug von glockenförmiger Gestalt insbesondere Bell-shaped tool in particular

für Dreh- und Bohrwerke. for turning and boring mills.

Die Erfindung betrifft ein Werkzeug von glockenfottniger Gestalt, insbesondere für Dreh- und Bohrwerke, mit stirnseitig gelagertem, durch die Hauptspindel hindurch von einem Vorschubgetriebe antreibbaren, das Werkzeug tragenden Planschieber. The invention relates to a tool of bell-shaped shape, in particular for turning and boring mills, with front-mounted bearings through the main spindle through by a feed gear drivable, the tool-carrying facing slide.

Häufig sind mit diesen Werkzeugen an den aufgespannten Werkstücken z.B. Turbinengehäusen, große und in Vorschubrichtung hinter diesen liegende kleinere Bohrungen oder Planflächen zu bearbeiten. Bedingt durch die notwendige Länge der Schlitten und ihrer Führungsbahnen kann das Werkzeug nur einen kleineren Bereich des größten Bearbeitungsdurchmessers bestreichen und kann auch nicht in kleinere Bohrungen eintauchen. Deshalb mußte bisher beim Übergang auf die kleineren Bearbeitungsdurchmesser der Kopf der Bohrglocke oder die gesamte Bohrglocke ausgewechselt werden. Das ist mit erheblichen Umständen und einem erheblichen Zeitaufwand verbunden. These tools are often used on the clamped workpieces E.g. turbine housings, large ones and smaller ones behind them in the direction of advance To machine holes or flat surfaces. Due to the necessary length of the The tool can only handle a small area of the slide and its guideways of the largest machining diameter and cannot be cut into smaller ones Immerse the holes. Therefore, up to now, when transitioning to the smaller machining diameter the head of the drill bell or the entire drill bell can be replaced. That is associated with considerable circumstances and a considerable expenditure of time.

Um diesen Nachteil zu vermeiden, wird erfindungsgemäß vorgeschlagen, einen weiteren, mit der Stirnseite der Bohrglocke verbundenen Werkzeugträger Bohrglocke, Bohrstange) geringeren Durchmessers, mit an seiner Stirnseite befindlichem, über ein Vorschubgetriebe verschieblichen Planschieber anzuordnen. In order to avoid this disadvantage, it is proposed according to the invention that another drill bell tool carrier connected to the face of the drill bell, Boring bar) of smaller diameter, with located on its face, over to arrange a feed gear displaceable facing slide.

Nach einer Einzelheit der ErZndung werden die automatisch angetriebenen Vorschubbewegungen des Planschiebers und des Werkzeugträgers von wechselweise einschaltbaren Kupplungen gesteuert. After a detail of the invention, they are automatically driven Feed movements of the facing slide and the tool carrier can be switched on alternately Controlled clutches.

In der Zeichnung ist ein Ausfüirunsbeispiel Ues Erfindungsgegenstandes schematisch dargestellt und zwar zeigen: Fig. 1 eine Seitenansicht der Werkzeugträger Fig. 2 einen Schnitt nach der Linie A-A in der Fig. 1 An der Stirnseite einer mit der Planscheibe eines nicht dargestellten Dreh- und ßohrwerkes verbundenen Bohrglocke 1 ist ein Querträger 2 befestigt. Auf ihm sind Werkzeug schieber 3 in Führungen und durch ein Vorschubgetriebe 4 verschiebbar angeordnet.In the drawing, an exemplary embodiment is the subject of the invention shown schematically and specifically show: FIG. 1 a side view of the tool carriers Fig. 2 shows a section along the line A-A in Fig. 1 at the end of one with the face plate of a rotary and ßbohrwerkes not shown connected drilling bell 1 a cross member 2 is attached. On it are tool slide 3 in guides and arranged displaceably by a feed gear 4.

Über den Querträger 2 ist ein Werkzeug träger 5 nlit eine Bohrkopf 6 gestülpt (Fig. 2) und an der Stirnseite der Bohrglocke 1 befestigt. Der dazugehörige Planschieber -7 wird mit seinem Werkzeug 8 ebenfalls vom Vorschubgetriebe 4 in üblicher Weise verschoben.About the cross member 2 is a tool carrier 5 nlit a drill head 6 turned upside down (FIG. 2) and attached to the end face of the drill bell 1. The associated Face slide -7 with its tool 8 is also used by the feed gear 4 in the usual way Way moved.

Das Vorschubgetriebe 4 wird durch die lçlittelbohrung der Bohrglocke 1 angetrieben und die Kupplungen 9 werden wechselweise für die Vorschubbewegung eines der gerade denötigten, mit z.B. verschiedenen Schneidengeometrieen ausgerüsteten Werkzeugen 7 oder lo oder auch des Werkzeuges 8 des Werkzeugträgers 5 eingeschaltet.The feed gear 4 is through the oil hole of the drill bell 1 driven and the clutches 9 are alternately for the feed movement one of the ones currently needed, e.g. equipped with different cutting edge geometries Tools 7 or lo or the tool 8 of the tool carrier 5 switched on.
