Abstract

The multi-spindle automatic lathe has horizontal workpiece spindles (9) on a common pitch circle in the frame (13), a feed and discharge mechanism (17), tools for internal and external machining operations, and a tool capstan drum (4) indexing on an axis parallel to the spindles and sliding in the axial direction. Tools (6) on the drum are on the same pitch circle and at the same pitch as the workpiece spindles, all of which they can reach in succession on indexing. The workpiece spindles are all in fixed positions, and have completely numerically-controlled cross-slides (10,12) with tools (8) for external machining. The tools can remain engaged with the workpieces during indexing of the drum.

Description

Bei der Patentanmeldung 40 12 290 (CNC-Mehrspindeldrehautomat) wurde keine spezifisch günstige Werkstückzu-/abführung vorgestellt.Patent application 40 12 290 (CNC multi-spindle automatic lathe) was not a specifically favorable workpiece feed / removal presented.

Es ist die Aufgabe vorliegender Erfindung dies nachzuholen. Diese Aufgabe wird erfindungsgemäß durch die in Anspruch 1 angegebenen Konstruktionsmerkmale gelöst. Die Unteransprüche erhalten weitere Ausgestaltungsmöglichkeiten.It is the object of the present invention to make up for this. This object is achieved by the in claim 1 specified design features solved. The subclaims receive further design options.

Der Vorteil der Erfindung besteht darin, daß die hohe Flexibilität des CNC-Mehrspindeldrehautomaten auch beim Werkstückzu-/abführsystem vorhanden ist. Weitere Vorteile sind die klare Trennung von Ladesystem und Maschine. Fast alle Elemente des Ladesystems können außerhalb des Spänebereichs angeordnet werden, was zu einer Minimierung der Störungen beiträgt. Ein Ladesystem kann beliebig viele ortsfeste Spindeln je Maschine bedienen. Die bearbeitenden Teile können spindelspezifisch einsortiert werden. Eine Integration von Reinigungs- oder Meßstation ist einfach.The advantage of the invention is that the high Flexibility of the CNC multi-spindle automatic lathe also with Workpiece feed / removal system is available. Other advantages are the clear separation of the loading system and the machine. Almost all Elements of the loading system can be outside the chip area be arranged, which minimizes interference contributes. A charging system can have any number of stationary Operate spindles per machine. The machining parts can sorted according to spindle. An integration of Cleaning or measuring station is simple.

Fig. 1 zeigt in Seitenansicht einen Anwendungsfall. Der Roboter (17) folgt der rundtaktenden Aussparung (16) im Werkzeugrevolver (4) und kann somit jede Werkstückspindel (9) bedienen. Fig. 2 zeigt die Draufsicht auf den Werkzeugrevolver (4) mit der die jeweilige Werkstückspindel (9) freigebenden Aussparung (16). Fig. 1 shows a side view of an application. The robot ( 17 ) follows the clocked recess ( 16 ) in the tool turret ( 4 ) and can therefore operate each workpiece spindle ( 9 ). Fig. 2 shows the top view of the tool turret ( 4 ) with the respective workpiece spindle ( 9 ) opening recess ( 16 ).
