Abstract

For the purpose of saving setting-up time on a lathe with two tool carriers (4, 5), adjustable independently of one another, and a steadyrest (7), it is proposed to releasably fasten the steadyrest (7) to one of the two tool carriers (5). <IMAGE>

Description

Die Erfindung betrifft eine Drehmaschine gemäß dem Oberbegriff des Patentanspruchs.The invention relates to a lathe according to the preamble of the claim.

Bei einer bekannten Drehmaschine dieser Art ist die Lünette am Maschinenbett verstellbar befestigt. Insoweit können damit alle anfallenden Dreharbeiten bewerkstelligt werden, jedoch müssen dabei - zumindest bei der Außenbearbeitung von relativ langen Werkstücken - erhebliche Umrüstzeiten für das meistens mehrmalige Versetzen der Lünette in Kauf genommen werden.In a known lathe of this type is the bezel adjustably attached to the machine bed. As far as it can all shooting is done, however have to do this - at least for the external machining of relative long workpieces - considerable changeover times for most of the time repeated relocations of the bezel are accepted.

Der Erfindung liegt daher die Aufgabe zugrunde, die Lünette so anzuordnen, daß ein aufwendiges Umrüsten nicht erforderlich ist. Bei einer gattungsgemäßen Drehmaschine wird diese Aufgabe durch das kennzeichnende Merkmal des Patentanspruchs gelöst.The invention is therefore based on the object, the bezel to be arranged so that a time-consuming changeover is not necessary is. In a generic lathe, this task solved by the characterizing feature of the claim.

Nach der Erfindung sind darüber hinaus für die Lünette bestimmte Halterungen am Maschinenbett überflüssig, oder - anders ausge­ drückt - auch an solchen Drehmaschinen, für die ursprünglich die Verwendung einer Lünette nicht vorgesehen war, kann ohne Aufwand eine Lünette nachgerüstet werden.According to the invention are also intended for the bezel Brackets on the machine bed superfluous, or - in other words presses - even on such lathes, for which originally the use of a bezel was not intended without Effort to retrofit a bezel.

Ein Ausführungsbeispiel der Erfindung wird anhand der Zeichnung näher erläutert. An embodiment of the invention is based on the drawing explained in more detail.  

Die nur schematisch dargestellte Drehmaschine, eine programmge­ steuerte Vier-Achsen-Drehmaschine, umfaßt im wesentlichen ein Maschinenbett 1, ein Aufnahmefutter 2, in das ein zu bearbeitendes Werkstück eingespannt wird, einen Reitstock 3, sowie einen oberen und einen unteren Werkzeugträger 4 und 5, die beide jeweils in zwei Achsen verfahrbar sind. Am unteren Werkzeugträger 5 ist bei 6 eine Lünette 7 lösbar befestigt, beispielsweise mittels eines üblichen Werkzeughalters, der einen schnellen Ein- und Ausbau gestattet. Die jeweils erforder­ lichen Positionen der Lünette 7, die selbstverständlich nur bei Bedarf angebaut wird, sind mit Hilfe des Werkzeugträgers 5 ohne Aufwand und schnell erreichbar, noch dazu mit hoher Genauigkeit. Die Bearbeitung des Werkstücks erfolgt mittels eines im oberen Werkzeugträger 4 befestigten Werkzeuges.The lathe, shown only schematically, a programmable four-axis lathe, essentially comprises a machine bed 1 , a receiving chuck 2 , in which a workpiece to be machined is clamped, a tailstock 3 , and an upper and a lower tool holder 4 and 5 , both of which can be moved in two axes. On the lower tool carrier 5 , a bezel 7 is detachably fastened at 6 , for example by means of a conventional tool holder, which allows quick installation and removal. The respective positions of the steady rest 7 , which is of course only installed when required, can be reached quickly and easily with the help of the tool carrier 5 , and moreover with high accuracy. The workpiece is processed by means of a tool fastened in the upper tool carrier 4 .
