Abstract
Die Erfindung betrifft eine Werkzeugmaschine mit einem Maschinengestell mit zwei Werkstückspindeln (8, 8') und mit einem Werkzeughalter (12) mit Werkzeugen (13), mit einer Transporteinrichtung (18) für die Werkstücke (10), mit einem Späneschutz (20) mit zwei Leitblechen (25, 25'), wobei der Werkzeughalter (12) am Maschinengestell verfahrbar angeordnet ist und wobei die Werkstücke (10) abwechselnd in den Werkstückspindeln (8, 8') mit den Werkzeugen (13) bearbeitbar sind, so dass gleichzeitig in der jeweils anderen Werkstückspindel (8, 8') das Werkstück (10) auswechselbar ist, wobei jede der Werkstückspindeln (8, 8') aus einer Arbeitsposition (17, 17'), in der die Werkstücke (10) bearbeitbar sind, in eine Ladeposition (19, 19') verfahrbar ist, wobei zum Be- und Entladen der Werkstückspindeln (8, 8') die Leitbleche (25, 25') aus den Bereichen zwischen den Arbeitspositionen (17, 17') und den Ladepositionen (19, 19') in Parkpositionen (26, 26') verfahrbar sind.The invention relates to a machine tool having a machine frame with two workpiece spindles (8, 8 ') and with a tool holder (12) with tools (13), with a transport device (18) for the workpieces (10), with a chip guard (20) two guide plates (25, 25 '), wherein the tool holder (12) is arranged movably on the machine frame and wherein the workpieces (10) in the workpiece spindles (8, 8') with the tools (13) are machined alternately, so that simultaneously the respective other workpiece spindle (8, 8 '), the workpiece (10) is replaceable, wherein each of the workpiece spindles (8, 8') from a working position (17, 17 '), in which the workpieces (10) are machined, in a Loading position (19, 19 ') is movable, wherein for loading and unloading of the workpiece spindles (8, 8') the baffles (25, 25 ') from the areas between the working positions (17, 17') and the loading positions (19, 19 ') in parking positions (26, 26') are movable.
Description
Die Erfindung betrifft eine Werkzeugmaschine nach dem Oberbegriff des Patentanspruchs 1. Bei nach dem Pendelprinzip arbeitenden Werkzeugmaschinen werden die Werkstücke in beiden Spindeln abwechselnd bearbeitet. Während in der einen Spindel ein Werkstück bearbeitet wird, kann die andere beladen werden. Das Pendelprinzip ist bei kurzen Bearbeitungszeiten besonders dann von Vorteil, wenn die Nebenzeiten gleich oder größer als die Bearbeitungszeiten sind. Um die Nebenzeiten zu senken, sind in der
Aufgabe der vorliegenden Erfindung ist es, Werkzeugmaschinen mit einem Maschinengestell mit zwei Werkstückspindeln zu vereinfachen, eine kompakte Bauweise aufzuzeigen und den Späneschutz gegen Austreten von Spänen aus dem Arbeitsraum zu verbessern. Diese Aufgabe wird gelöst durch eine Werkzeugmaschine nach Patentanspruch 1. Vorteilhafte Ausführungen ergeben sich aus den Unteransprüchen.Object of the present invention is to simplify machine tools with a machine frame with two workpiece spindles to show a compact design and to improve the chip protection against leakage of chips from the workspace. This object is achieved by a machine tool according to
Da bei den Drehmaschinen mit Pendelprinzip die Späne abwechselnd an den beiden Spindeln anfallen, müssen diese auch im Wechsel beladen bzw. abgeschirmt werden. Besonders bei kompakten Maschinen steht für den Späneschutz nur sehr wenig Raum zur Verfügung.Since, in the lathes with pendulum principle, the chips occur alternately on the two spindles, they must also be loaded alternately or shielded. Especially with compact machines there is very little space available for chip protection.
Gemäß einem vorteilhaften Aspekt der Erfindung ist beiden Werkstückspindeln ein teleskopierbarer Späneschutz zugeordnet, der wahlweise jeweils eine oder bei Bedarf auch beide Werkstückspindeln gleichzeitig abschirmt. Im Folgenden wird die Erfindung an Hand eines Ausführungsbeispiels näher beschrieben. Es zeigen:According to an advantageous aspect of the invention, a pair of telescoping chip protection is associated with both workpiece spindles, which optionally shield one or, if required, both workpiece spindles simultaneously. The invention will be described in more detail below with reference to an exemplary embodiment. Show it:
