Abstract

A pillar (2) is mounted on a baseplate (1). The pillar, the height of which is adjustable, can rotate about its own axis and can be moved longitudinally on the base plate. On the top of the pillar a semicircular bearing piece (3) is mounted which in turn holds a swivelling cradle arrangement (5). The cradle arrangement has a workholding table (6) mounted on it which can be rotated and moved transversely. Movement in any or all of the axes is facilitated by means of electric or hydraulic motors and a programmable controller. USE/ADVANTAGE - Holder for workpiece provides seven additional adjustable axes within the confines of a normally 3 axis machine coordinate system.

Description

Die Erfindung betrifft eine Aufnahmevorrichtung für Werk­ stücke od. dgl. zur Durchführung von z. B. Materialbearbei­ tungsprozessen auf Werkzeugmaschinen, die eine positionsge­ naue Einstellung und automatische Führung des Werkstückes in­ nerhalb eines dreidimensionalen Koordinatensystems oder auch das kontinuierliche Schwenken des Werkstückes und dergleichen Objekte zur Fünf-Seiten-Bearbeitung ermöglicht. Speziell im Werkzeugmaschinenbau sind Schwenktische und ähnliche Einrich­ tungen zur Mehrseitenbearbeitung von Werkstücken bekanntge­ worden und mehrfach in der Patentliteratur beschrieben.The invention relates to a receiving device for work pieces or the like for carrying out z. B. Material processing processes on machine tools that require a position Precise setting and automatic guidance of the workpiece within a three-dimensional coordinate system or also the continuous swiveling of the workpiece and the like Objects for five-sided editing enabled. Especially in Machine tool construction are swivel tables and similar devices notices for multi-sided machining of workpieces been and described several times in the patent literature.

Diese Einrichtungen sind zur Verwendung bei zerspanenden Werkzeugmaschinen, insbesondere Fertigungszellen oder Waage­ recht-Bearbeitungszentren, gedacht und so konstruiert, daß der Entriegelungs- und Schwenkmechanismus entweder durch die Werkzeugmaschinenspindel über ein Andruckelement (DD 2 49 663) oder von einem Spezialwerkzeug über einrichtungsinterne Mit­ tel zentral betätigt wird (DD 2 73 395). Daraus ergibt sich, daß zwar eine Werkstückbearbeitung von 5 Seiten her möglich ist, aber während der Bearbeitung selbst die Werkstücklage nicht verändert werden kann (und soll). Diese Einrichtungen sind wegen der Art des Schwenkantriebes zudem nur an mecha­ nischen Bearbeitungsmaschinen der genannten Arten einsetzbar.These devices are for use in machining Machine tools, in particular manufacturing cells or scales right machining centers, thought and constructed so that the unlocking and swiveling mechanism either through the Machine tool spindle via a pressure element (DD 2 49 663) or from a special tool via in-house Mit tel is operated centrally (DD 2 73 395). This results in, that workpiece processing is possible from 5 sides but the workpiece position itself during machining cannot (and should not) be changed. These facilities are only on mecha because of the type of rotary actuator African processing machines of the types mentioned can be used.

Somit werden die Fälle nicht erfaßt, wo während der Behand­ lung mit entsprechenden Behandlungsmethoden eine positions­ genaue Einstellung und automatische Führung des Werkstückes (Objektes) innerhalb eines dreidimensionalen Koordinaten­ systems notwendig ist, z. B. zur Laserbearbeitung. Die Er­ findung stellt sich nunmehr die Aufgabe, eine Aufnahmevor­ richtung für Werkstücke oder dergleichen Objekte zu schaf­ fen, die sich durch eine hohe Anzahl von z. B. rechnerge­ steuerten Bewegungskombinationen auszeichnet und somit die kontinuierliche Durchführung von 5-Seiten-Behandlungs­ prozessen unter einem im wesentlichen feststehenden, in der Regel vertikal wirkenden Behandlungsmedium ermöglicht.Thus, the cases are not recorded where during treatment a position with appropriate treatment methods precise setting and automatic guidance of the workpiece (Object) within a three-dimensional coordinate systems is necessary, e.g. B. for laser processing. The he The task now arises, a pre-recording direction for workpieces or similar objects fen, which is characterized by a large number of z. B. computer controlled movement combinations and thus the continuous implementation of 5-sided treatment processes under an essentially fixed,  usually allows vertically acting treatment medium.

Die erfindungsgemäße Lösung besteht aus einer Grundplatte, einem Säulenkörper, einem Tragelement in einer halbkreisför­ migen Führungsbahn und einer Brücke mit dem Aufspanntisch, deren Anordnung und weitere Einzelheiten in Anspruch 1 näher beschrieben sind.The solution according to the invention consists of a base plate, a column body, a support element in a semicircular guideway and a bridge with the clamping table, their arrangement and further details in claim 1 are described.

Erfindungsgemäß ist vorgesehen, daß alle Bewegungen dieser Elemente einzeln, nacheinander, im Komplex oder unabhängig voneinander mittels integrierter Stellantriebe erfolgen, die ihrerseits in bekannter Weise über Rechner angesteuert werden können.According to the invention it is provided that all movements of this Elements individually, one after the other, in a complex or independently from each other by means of integrated actuators that in turn can be controlled in a known manner via computers can.

Die vorteilhafte Wirkung dieser Erfindung besteht darin, daß sich sieben Bewegungsachsen ergeben, davon sind vier Rota­ tions- und drei Translationsbewegungen, die insgesamt die Er­ füllung der Aufgabenstellung unter Einhaltung genauester Po­ sitionen innerhalb der drei Koordinaten gewährleisten.The advantageous effect of this invention is that there are seven axes of movement, four of which are rota tion and three translational movements, the total Er Filling the task in compliance with the most precise bottom ensure positions within the three coordinates.

Die Erfindung ist nachstehend anhand von Ausführungsbeispie­ len und Zeichnungen näher erläutert. Es zeigtThe invention is based on exemplary embodiments len and drawings explained in more detail. It shows

Auf einer mit einer Führungsbahn versehenen Grundplatte (1) befindet sich in senkrechter Lage ein teleskopartiger Säulen­ körper (2), der in seiner Höhe verstellbar und zugleich dreh­ bar ausgebildet ist. Auf diesem ruht ein Sockel zur Aufnahme eines gabelartigen Tragelementes (3), das in einer halbkreis­ förmigen Führungsbahn (4) um mindestens 180° drehbar gelagert ist. Zwischen den Gabelenden ist eine in Zapfen gelagerte, verschiedenartig geformte Brücke (5) entsprechend Fig. 1, 2 oder 3 angeordnet, die um ihre Längsachse schwenkbar ist und den eigentlichen Aufspanntisch (6) trägt, der seinerseits in Längsrichtung der Brücke verschiebbar und ebenfalls drehbar gelagert ist. On a base plate provided with a guideway ( 1 ) there is a telescopic column body ( 2 ) in a vertical position, the height of which is adjustable and at the same time is designed to rotate. On this rests a base for receiving a fork-like support element ( 3 ) which is mounted in a semicircular guideway ( 4 ) rotatable by at least 180 °. Between the fork ends, a differently shaped bridge ( 5 ) according to FIGS. 1, 2 or 3, which is pivoted about its longitudinal axis and carries the actual clamping table ( 6 ), which in turn can be displaced in the longitudinal direction of the bridge and is also rotatable, is arranged in the journal is stored.

Alle nach dieser Beschreibung möglichen Bewegungsfunktionen sind jede für sich mit einem an sich bekannten, elektrischen oder hydraulischen Stellantrieb realisierbar und so ausge­ führt, daß sie mit einer programmierbaren Steuerung gekoppelt jede gewünschte Relativbewegung des Werkstückes innerhalb des dreidimensionalen Koordinatensystems ermöglichen.All movement functions possible according to this description are each with an electrical known per se or hydraulic actuator can be realized and so out leads to it being coupled to a programmable controller any desired relative movement of the workpiece within the enable three-dimensional coordinate system.

Diese Aufnahmevorrichtung wird z. B. bei Laserbearbeitungs­ maschinen angewandt, um konturengenaue Abtragungen an For­ men, Preßwerkzeugen usw. herstellen zu können.This cradle is, for. B. in laser processing machines are used to ensure precise removal of contours from For men, pressing tools, etc. to be able to manufacture.

Eine weitere Anwendungsmöglichkeit ergibt sich auch als Auf­ nahmevorrichtung für Röntgen-, Ultraschalluntersuchungs- oder Bestrahlungsanlagen, wenn die Brücke (5) beispielsweise als Patientenliege ausgebildet ist.Another possible application also arises as a recording device for X-ray, ultrasound or radiation systems, if the bridge ( 5 ) is designed, for example, as a patient couch.
