Abstract

The machine tool has two workpiece supports (1,2) mounted in a machine frame and mounted on and between two swivel supports (6) of which at least one is double-armed to allow unhindered automatic workpiece loading. The pressurised medium used for hydraulically operating the workpiece clamps is supplied through a rotary distributor, through ducts in the support and through rotary guides.

Description

Die vorliegende Erfindung bezieht sich auf eine Werkzeugmaschine mit zwei Werkstückträgern die im Maschinengestell zwischen und an zwei schwenkbaren Schwenkträgern gelagert die um eine horizontale Zentralachse wechselweise von der Bestückungsseite in die Bearbeitungsseite schwenkbar sind.The present invention relates to a machine tool with two Workpiece carriers in the machine frame between and on two swiveling Swivel beams are mounted alternately from the around a horizontal central axis The component side can be pivoted into the processing side.

Schwenkbare Werkstückträger dieser Art sind z. B. in horizontalen Bearbeitungszentren der Schwäbischen Werkzeugmaschinen GmbH bekannt. Die beiden auf einer horizontalen Achse schwenkbar gelagerten Schwenkträger, zwischen und an diesen die beiden Werkstückträger drehbar gelagert sind, nehmen an ihrer dem Maschinengestell zugewandten Seite die schwenkbar angeordneten hydraulischen Zuleitungen für die Betätigung der Werkstückspannvorrichtungen und die Drehantriebe für die beiden Werkstückträger auf. Diese Schwenkträger sind deshalb als Scheiben mit kreisbogenförmiger Randbegrenzung ausgebildet, um so auch einen Spritzschutz für diese Funktionsaggregate zu gewährleisten. Nachteilig verhindern diese scheibenförmigen Schwenkträger eine platzsparende automatische Werkstückzuführung parallel zur Längsachse der Werkstückträger im Beladeraum.Swiveling workpiece carriers of this type are e.g. B. in horizontal machining centers Schwäbischen Werkzeugmaschinen GmbH known. The two on a horizontal Axially pivoted swivel bracket, the two between and on these Workpiece carriers are rotatably mounted on the machine frame facing side the pivotably arranged hydraulic feed lines for the Actuation of the workpiece clamping devices and the rotary drives for the two Workpiece carrier on. These swivel beams are therefore in the form of disks with a circular arc Edge boundary designed to also provide a splash guard for to ensure these functional units. Disadvantageously, these prevent disc-shaped Swivel bracket a space-saving automatic workpiece feed parallel to Longitudinal axis of the workpiece carriers in the loading area.

Aufgabe der vorliegenden Erfindung ist die Ausbildung einer Werkzeugmaschine mit schwenkbaren Werkstückträgern derart, dass eine ungehinderte automatische Werkstückbeladung parallel zur Längsachse der Werkstückträger möglich ist, was eine konstruktive Änderung der Schwenkträger-Scheibenform und damit eine Änderung der hydraulischen Zuführungen wie auch der Drehantriebe bedingt.The object of the present invention is to form a machine tool swiveling workpiece carriers such that an unimpeded automatic Workpiece loading parallel to the longitudinal axis of the workpiece carrier is possible, which is a constructive change in the swivel beam disc shape and thus a change in hydraulic feeds as well as the rotary drives.

Zur Lösung dieser Aufgabe ist erfindungsgemäß vorgesehen, dass mindestens ein Schwenkträger zweiarmig ausgebildet ist. Eine derartige konstruktive Ausgestaltung eines Schwenkträgers gewährleistet eine automatische Werkstückzuführung parallel zur Längsachse der Werkstückträger.To achieve this object, the invention provides that at least one Swivel bracket is designed with two arms. Such a design A swivel bracket ensures automatic workpiece feed parallel to Longitudinal axis of the workpiece carrier.

Die Lösung dieser Aufgabe bedingt ferner, dass ein Schwenkträger für das hydraulische Druckmedium mit einem zentralen Drehverteiler und mit Drehdurchführungen zu den Werkstückträgern, sowie Kanälen zu den hydraulischen Werkstück-Spannvorrichtungen ausgerüstet ist. Hierdurch werden die sonst außen angeordneten und den seitlichen Zugang behindernden hydraulischen Leitungen eliminiert.The solution to this problem also requires that a swivel bracket for the hydraulic Print medium with a central rotary distributor and with rotary unions to the Workpiece carriers, as well as channels to the hydraulic workpiece clamping devices is equipped. As a result, the otherwise external and lateral access obstructing hydraulic lines eliminated.

Desweiteren ist für die Lösung der Aufgabe vorteilhaft, dass der Drehantrieb für den im Arbeitsraum befindlichen Werkstückträger an- und abkuppelbar gestaltet ist. Damit wird der für die automatische Werkstückbeladung notwendige seitliche Zugang begünstigt. Vorteilhaft entfällt die Belastung durch mitschwenkende Aggreate und der zweite Drehantrieb im Beladeraum. Außerdem unterstützt vorteilhafterweise die Halterung und Führung des mit dem Maschinengestell verbundenen kuppelbaren Drehantriebs die Abstützung des im Arbeitsraum befindlichen Werkstückträgers.Furthermore, it is advantageous for the solution of the task that the rotary drive for the Workspace located workpiece carrier is designed to be coupled and uncoupled. So that will the lateral access necessary for the automatic workpiece loading favors. Advantageously, there is no stress caused by the aggreate and the second that pivot Rotary drive in the loading area. In addition, the bracket and advantageously supports Guidance of the detachable rotary drive connected to the machine frame Support of the workpiece carrier located in the work area.

Die zeichnerischen Darstellungen verdeutlichen den Erfindungsgedanken.The graphic representations illustrate the idea of the invention.

Fig. 1 zeigt den erfindungsgemäßen zweiarmigen Schwenkträger mit den Lagerungen der beiden Werkstückträger am Schwenkträger. (Schnitt A-A in Fig. 2) Fig. 1 shows the two-armed swivel bracket according to the invention with the bearings of the two workpiece carriers on the swivel bracket. (Section AA in FIG. 2)

Fig. 2 zeigt die Draufsicht zu Fig. 1 mit den erfindungsgemäß angeordneten Aggregaten für Druckmedium und Antrieb. FIG. 2 shows the top view of FIG. 1 with the units for pressure medium and drive arranged according to the invention.

Wie in den Fig. 1 und 2 dargestellt, ist der die Werkstückträger (I) und (2) über Drehlager (3) und (4) aufnehmende, um eine horizontale Achse (5) schwenkbare Schwenkträger (6) erfindungsgemäß zweiarmig gestaltet. Mit dieser Gestaltung ist der Weg für eine Bewegung des Greifers (7) in X-Richtung fair die automatische Beladung der Werkstücke (8) freigegeben. Mit der an sich bekannten Trennwand (9) ist ein Spritzschutz zwischen dem Beladeraum (10) und dem Arbeitsraum (11) gewährleistet.As shown in FIGS. 1 and 2, the workpiece carrier is receiving via rotary bearings (3) and (4), designed according to the invention with two arms about a horizontal axis (5) pivotable swivel support (6) (I) and (2). With this design, the path for a movement of the gripper ( 7 ) in the X direction is fairly cleared for the automatic loading of the workpieces ( 8 ). With the partition ( 9 ) known per se, splash protection between the loading space ( 10 ) and the working space ( 11 ) is ensured.

Das die hydraulische Betätigung der Werkstück-Spannvorrichtungen bewirkende Druckmedium wird über einen Drehverteiler (12), über im Schwenkträger (6) vorgesehene Kanäle (13) und Drehdurchführungen (14) und weiteren nicht dargestellten Kanälen in den Werkstückträgern (1) und (2) den Spannvorrichtungen für die Werkstücke (8) zugeleitet.The pressure medium effecting the hydraulic actuation of the workpiece clamping devices is via a rotary distributor ( 12 ), via channels ( 13 ) and rotary feedthroughs ( 14 ) provided in the swivel bracket ( 6 ) and other channels (not shown) in the workpiece holders ( 1 ) and ( 2 ) Clamps for the workpieces ( 8 ) fed.
