Aufnahmevorrichtung für WerkstückeHolding device for workpieces

Die Erfindung betrifft eine Aufnahmevorrichtung für Werkstücke o· dgl· zur Durchführung von z. B· Materialbearbeitungsprozessen auf Werkzeugmaschinen, die eine positionsgenaue Einstellung und automatische Führung des Werkstückes innerhalb 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 Einrichtungen zur Mehrseitenbearbeitung von Werkstücken bekannt geworden und mehrfach in der Patentliteratur beschrieben. Diese Einrichtungen sind zur Verwendung bei zerspanenden Werkzeugmaschinen, insbesondere Fertigungszellen oder Waagerecht-Bearbeitungszentren, gedacht und so konstruiert, daß der Entriegelungs- und Schwenkmechanismus entweder durch die Werkzeugmaschinenspindel über ein Andruckelement (DD 249 663) oder von einem Spezialwerkzeug über einrichtungsinterne Mittel zentral betätigt wird (DD 273 395)· 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 mechanischen Bearbeitungsmaschinen der genannten Arten einsetzbar· Somit werden die Fälle nicht erfaßt, wo während der Behandlung mit entsprechenden Behandlungsmethoden eine positionsgenaue Einstellung und automatische Führung des Werkstückes (Objektes) innerhalb eines dreidimensionalen Koordinatensystems notwendig ist, z. B. zur Laserbearbeitung· Die Erfindung stellt sich nunmehr die Aufgabe, eine Aufnahmevorrichtung für Werkstücke oder dergleichen Objekte zu schaffen, die sich durch eine hohe Anzahl von z. B· rechnergesteuerten Bewegungskombinationen auszeichnet und somit die kontinuierliche Durchführung von 5-Seiten-Behandlungsprozessen unter einem im wesentlichen feststehenden,The invention relates to a holding device for workpieces or the like for carrying out material processing processes on machine tools, for example, which enables precise positioning and automatic guidance of the workpiece within a three-dimensional coordinate system or also the continuous swiveling of the workpiece and similar objects for five-sided machining. Swivel tables and similar devices for multi-sided machining of workpieces have become known, especially in machine tool construction, and have been described several times in the patent literature. These devices are intended for use with cutting machine tools, in particular production cells or horizontal machining centers, and are designed in such a way that the unlocking and swivel mechanism is operated centrally either by the machine tool spindle via a pressure element (DD 249 663) or by a special tool via means internal to the device (DD 273 395) · This means that although workpiece processing from 5 sides is possible, the workpiece position cannot (and should not) be changed during processing itself · Due to the type of swivel drive, these devices can also only be used on mechanical processing machines of the types mentioned · This means that cases are not covered where, during processing using appropriate processing methods, precise positioning and automatic guidance of the workpiece (object) within a three-dimensional coordinate system is necessary, e.g. B. for laser processing. The invention now has the task of creating a holding device for workpieces or similar objects, which is characterized by a high number of e.g. computer-controlled movement combinations and thus the continuous execution of 5-sided treatment processes under an essentially fixed,

in der Regel vertikal wirkenden Behandlungsmedium ermöglicht« Die erfindungsgemäße Lösung besteht aus einer Grundplatte, einem Säulenkörper, einem Tragelement in einer halbkreisförmigen Pührungsbahn 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 guide track and a bridge with the clamping table, the arrangement and further details of which are described in more detail in claim 1·

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, all movements of these elements take place individually, one after the other, in a complex or independently of one another by means of integrated actuators, which in turn can be controlled in a known manner via a computer.

Die vorteilhafte Wirkung dieser Erfindung besteht darin, daß sich sieben Bewegungsachsen ergeben, davon sind vier Rotations- und drei Translationsbewegungen, die insgesamt die Erfüllung der Aufgabenstellung unter Einhaltung genauester Positionen innerhalb der drei Koordinaten gewährleisten· Die Erfindung ist nachstehend anhand von Ausführungsbeispielen und Zeichnungen näher erläutert.
Es zeigenThe advantageous effect of this invention is that seven axes of movement are obtained, of which four are rotational and three are translational movements, which together ensure that the task is fulfilled while maintaining the most precise positions within the three coordinates. The invention is explained in more detail below using embodiments and drawings.

Auf einer mit einer Führungsbahn versehenen Grundplatte (1) befindet sich in senkrechter Lage ein teleskopartiger Säulenkörper (2), der in seiner Höhe verstellbar und zugleich drehbar ausgebildet ist. Auf diesem ruht ein Sockel zur Aufnahme eines gabelartigen Tragelementes (3), das in einer halbkreisförmigen Führungsbahn (4) um mindestens 180° drehbar gelagert ist. Zwischen den Gabelenden ist eine in Zapfen gelagerte, verschiedenartig geformte Brücke (5) entsprechend Figur 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.A telescopic column body (2) is located vertically on a base plate (1) provided with a guide track. The column body is adjustable in height and can also be rotated. A base rests on this to accommodate a fork-like support element (3) which is mounted in a semicircular guide track (4) so that it can rotate by at least 180°. Between the ends of the forks there is a bridge (5) of various shapes, mounted in pins, as shown in Figure 1, 2 or 3, which can be pivoted about its longitudinal axis and carries the actual clamping table (6), which in turn can be moved in the longitudinal direction of the bridge and is also mounted so that it can rotate.

Alle nach dieser Beschreibung möglichen Bewegungsfunktionen sind jede für sich mit einem an sich bekannten, elektrischen oder hydraulischen Stellantrieb realisierbar und so ausgeführt, daß sie mit einer programmierbaren Steuerung gekoppelt jede gewünschte Relativbewegung des Werkstückes innerhalb des dreidimensionalen Koordinatensystems ermöglichen· Diese Aufnahmevorrichtung wird z. B. bei Laserbearbeitungsmaschinen angewandt, um konturengenaue Abtragungen an Formen, Preßwerkzeugen usw· herstellen zu können· Eine weitere Anwendungsmöglichkeit ergibt sich auch als Aufnahmevorrichtung für Röntgen-, Ultraschalluntersuchungs- oder Bestrahlungsanlagen, wenn die Brücke (5) beispielsweise als Patientenliege ausgebildet ist.All movement functions possible according to this description can be implemented individually with a known electrical or hydraulic actuator and are designed in such a way that, when coupled with a programmable control, they enable any desired relative movement of the workpiece within the three-dimensional coordinate system. This holding device is used, for example, in laser processing machines in order to be able to produce contour-accurate removals on molds, pressing tools, etc. Another possible application is as a holding device for X-ray, ultrasound examination or radiation systems if the bridge (5) is designed, for example, as a patient bed.
