Es ist eine Maschine für die Fertigbearbeitung von Werkstükken bekannt, die aus einer drehbaren Trommel, in welcher die Werkstücke bearbeitet werden, und aus einer Einrichtung für das Laden und Entladen besteht. Die Einrichtung für die Zuführung der Werkstücke zur Trommel und ihre Entnahme nach der Bearbeitung ist als Manipulator mit Greifern gebaut. Die Trommel, in der die Werkstücke bearbeitet werden, hat einen Arbeitsbereich in Form eines Torus, der von einem Boden und von zylindrischen Wänden gebildet wird, die am Boden befestigt sind. Im Arbeitsbereich wird eine Schleifmittelmischung eingeführt (JP-C-46/10 399).A machine for the finishing of workpieces is known, which consists of a rotatable drum in which the workpieces are processed and of a device for loading and unloading. The facility for the Feeding the workpieces to the drum and removing them after processing is built as a manipulator with grippers. The drum in which the workpieces are processed has a work area in the form of a torus, which is formed by a base and by cylindrical walls which are attached to the base.

Ein Nachteil dieser bekannten Maschine liegt darin, daß bei dem Polieren von Werkstücken mit kompliziertem Profil Kanten abgerundet werden, was unerwünscht ist.A disadvantage of this known machine is that edges are rounded when polishing workpieces with a complicated profile, which is undesirable.

Der Erfindung liegt die Aufgabe zugrunde, eine Maschine für die Fertigbearbeitung zu schaffen, zum Beispiel für das Polieren von Werkstücken mit kompliziertem Profil, mit welcher alle Oberflächen gleichmäßig bearbeitet werden können.The invention has for its object to provide a machine for finishing, for example for polishing workpieces with a complicated profile, with which all surfaces can be machined evenly.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Arbeitsbereich in Form des Torus der Trommel von oben durch einen unbeweglichen Magnetkern abgeschlossen ist und daß im Zentrum des Arbeitsbereiches eine elektromagnetische Spule und eine starr am Magnetkern befestigte Scheibe angeordnet sind. Die zylindrischen Wände des Arbeitsbereichs mit der Form eines Torus bestehen aus nichtferromagnetischem Werkstoff, während der Boden, die Scheibe und die Achse aus ferromagnetischem Werkstoff hergestellt sind. Der Boden der Trommel ist durch einen Flansch an der starren Achse gelagert.This object is achieved in that the work area in the form of the torus of the drum is closed from above by an immovable magnetic core and that an electromagnetic coil and a disk rigidly attached to the magnetic core are arranged in the center of the work area. The cylindrical walls of the work area with the shape of a torus are made of non-ferromagnetic material, while the bottom, the disc and the axis are made of ferromagnetic material. The bottom of the drum is supported by a flange on the rigid axle.

Die Maschine für die Fertigbearbeitung von Werkstücken mit kompliziertem Profil kann zum Beispiel sechs Arbeitsstationen aufweisen, die oberhalb des Arbeitsbereichs der zentrifugalen Trommel angeordnet sind, die einen unteren, sich schnell drehenden Magnetpol aufweist. Jede Arbeitsstation ist mit einem Elektromotor, Untersetzungsgetriebe und einer Spindel versehen, an der ein Futter für das Einspannen des Werkstücks befestigt ist. Das diskrete Drehen aller Arbeitsstationen, zusammen mit dem oberen Magnetkern erfolgt durch einen separaten Elektromotor mit Untersetzungsgetriebe und Kettenzahngetrieben. Ein zentraler Kontaktkollektor speist die Arbeitsstationen. In der ersten Arbeitsposition wird die Arbeitsstation durch einen pneumatischen Zylinder gehoben, wobei die fertig bearbeiteten Werkstücke entnommen und unbearbeitete eingesetzt werden können. Bei allen übrigen Positionen sind die Arbeitsstationen in entsprechende öffnungen im oberen Magnetkern abgesenkt.The machine for finishing workpieces with a complicated profile can, for example, have six work stations which are arranged above the work area of the centrifugal drum, which has a lower, rapidly rotating magnetic pole. Any work station is equipped with an electric motor, reduction gear and a spindle to which a chuck for clamping the workpiece is attached. The discreet rotation of all workstations, together with the upper magnetic core, is carried out by a separate electric motor with reduction gear and chain tooth gears. A central contact collector feeds the work stations. In the first working position, the work station is lifted by a pneumatic cylinder, whereby the finished workpieces can be removed and unprocessed ones can be used. In all other positions, the workstations are lowered into corresponding openings in the upper magnetic core.

Die Vorteile der Erfindung bestehen darin, daß die Qualität der bearbeiteten Werkstücke ohne Änderungen ihrer geometrischen Form verbessert wird, wobei die Bearbeitung aller Oberflächen gleichzeitig erfolgt.The advantages of the invention are that the quality of the machined workpieces is improved without changing their geometric shape, the machining of all surfaces taking place simultaneously.

Die erfindungsgemäße Maschine für die Fertigbearbeitung von Werkstücken mit kompliziertem Profil besteht aus einer Trommel 1, die über einen Riementrieb 2 von einem Elektromotor 3 angetrieben wird. Die Trommel 1 ist in einem Gehäuse 4 gelagert und hat einen Arbeitsbereich 5 mit der Form eines Torus, der von einem Boden 6 und zylindrischen Wänden 7 umgeben und oben von einem unbeweglichen Magnetkern 8 abgeschlossen ist. Die Wände 7 sind am Boden 6 befestigt. Im Zentrum des Arbeitsbereichs 5 befinden sich eine elektromagnetische Spule 9 und eine Scheibe 10, die an einer starren Achse 11 angebracht sind, welche an dem unbeweglichen Magnetkern 8 befestigt ist. Der Boden 6, die starre Achse 11 und die Scheibe 10 bestehen aus ferromagnetischem Werkstoff, während die zylindrischen Wände 7 des torusförmigen Arbeitsbereichs 5 aus nichtferromagnetischem Werkstoff hergestellt sind. Der Boden 6 der Trommel 1 ist mit einem Flansch 21 auf der starren Achse 11 gelagert.The machine according to the invention for the finishing of workpieces with a complicated profile consists of a drum 1 which is driven by an electric motor 3 via a belt drive 2. The drum 1 is in a ge housed 4 and has a work area 5 with the shape of a torus, which is surrounded by a bottom 6 and cylindrical walls 7 and is closed at the top by an immovable magnetic core 8. The walls 7 are attached to the floor 6. In the center of the working area 5 there are an electromagnetic coil 9 and a disk 10 which are attached to a rigid axis 11 which is attached to the immovable magnetic core 8. The bottom 6, the rigid axis 11 and the disk 10 are made of ferromagnetic material, while the cylindrical walls 7 of the toroidal working area 5 are made of non-ferromagnetic material. The bottom 6 of the drum 1 is mounted with a flange 21 on the rigid axis 11.

Die Maschine kann mit mehreren Trommeln 1 ausgerüstet sein. Diese Trommeln 1 sind kreisförmig angeordnet. Im Zentrum dieses Kreises ist eine Einrichtung für die Zuführung und die Entnahme der Werkstücke angeordnet, zum Beispiel ein Manipulator mit Greifern 12. Die Greifer 12 des Manipulators können sich in senkrechter Richtung bewegen und sich um ihre Achsen drehen. An den Greifern 12 des Manipulators sind Platten 13 mit Lagern 14, sowie ein Mechanismus für einen Teilungsvorschub 15 und ein Fixiermechanismus 16 angebracht. An den Platten 13 sind Zangenvorrichtungen 17 für das Greifen der Werkstücke montiert. Die Werkstücke werden an die Zangenvorrichtungen 17 durch eine Einrichtung 18 für orientierten Vorschub zugeführt, wobei sie nach Beendigung der Bearbeitung von der Zangenvorrichtung 17 von einer Förder-Entlade-Einrichtung 19 mit einem Kontrollblock 20 entfernt werden. Die Wirkungsweise der erfindungsgemäßen Maschine ist wie folgt:

  • Der torusförmige Arbeitsbereich 5 wird mit einer ferromagnetischen Schleifmittelmischung gefüllt. Danach werden durch die Einrichtung 18 für den orientierten Vorschub 18 Werkstücke zur Zangenvorrichtung 17 zugeführt. Durch Betätigung des Manipulators bewegen sich seine Greifer aufwärts, wonach sie durch die Zangenvorrichtung 17 über den torusförmigen Arbeitsbereich 5 der zentrifugalen Trommel 1 geschwenkt werden. Die Trommel 1 beginnt sich zu drehen und die Greifer 12 des Manipulators bewegen sich zusammen mit den Zangenvorrichtungen 17 abwärts, bis die Werkstücke in der ferromagnetischen Schleifmittelmischung, die den Arbeitsbereich 5 ausfüllt, eingetaucht werden. Dann wird die elektromagnetische Spule 9 eingeschaltet, die ein magnetisches Feld mit entsprechender Orientierung erzeugt. Die bearbeiteten Werkstücke werden gedreht, wobei das Polieren ihrer Oberflächen erfolgt.
The machine can be equipped with several drums 1. These drums 1 are arranged in a circle. In the center of this circle there is a device for feeding and removing the workpieces, for example a manipulator with grippers 12. The grippers 12 of the manipulator can move in the vertical direction and rotate about their axes. On the grippers 12 of the manipulator plates 13 with bearings 14, as well as a mechanism for a division feed 15 and a fixing mechanism 16 are attached. Pliers 17 for gripping the workpieces are mounted on the plates 13. The workpieces are fed to the tongs 17 by means of an oriented feed device 18, and after the machining is finished they are removed from the tongs 17 by a conveyor-unloading device 19 with a control block 20. The machine according to the invention works as follows:
  • The toroidal work area 5 is filled with a ferromagnetic abrasive mixture. Thereafter, the device 18 for the oriented feed 18 Workpieces supplied to the pliers device 17. When the manipulator is actuated, its grippers move upwards, after which they are pivoted by the forceps device 17 over the toroidal working area 5 of the centrifugal drum 1. The drum 1 begins to rotate and the grippers 12 of the manipulator move down together with the pliers 17 until the workpieces are immersed in the ferromagnetic abrasive mixture that fills the work area 5. Then the electromagnetic coil 9 is switched on, which generates a magnetic field with appropriate orientation. The machined workpieces are rotated, polishing their surfaces.

Nach Beendigung der Bearbeitung bewegen sich die Greifer 12 des Manipulators wieder aufwärts und drehen sich. Die Werkstücke gelangen dadurch in den Arbeitsbereich einer anderen, analogen zentrifugalen Trommel 1, die sich in entgegengesetzter Richtung dreht. Nach Beendigung der Bearbeitung befinden sich die Werkstücke über der Ausgangsposition. Sie werden durch die Entnahmeeinrichtung 19 mit dem Kontrollblock 20 von den Zangenvorrichtungen 17 entfernt.After the processing is finished, the grippers 12 of the manipulator move upwards again and rotate. The workpieces thereby reach the work area of another, analog centrifugal drum 1, which rotates in the opposite direction. After the machining is finished, the workpieces are above the starting position. They are removed from the pliers devices 17 by the removal device 19 with the control block 20.
