Abstract

Machine for finishing complex profiled workpieces having a rotating barrel where the workpieces are machined in an loading/unloading unit, for example, a manipulator with grippers. The barrel has a torus-shaped work area defined by a bottom and cylindrical walls fixed to the bottom and the torus-shaped work area of the barrel is closed at the top with a stationary magnetic pole piece. In the center of the torus-shaped work area there is located an electromagnetic coil and a disc mounted on the magnetic pole piece through a fixed shaft. The cylindrical walls of the torus-shaped work area are made of non-ferromagnetic material while the bottom of the shaft and the disc are made of ferromagnetic material. The advantages of the machine are that the quality of the surfaces as machined is improved without changes in the geometry of the workpieces, and machining is carried out on preselected surfaces only.

Description

Die Erfindung betrifft eine Maschine für die Fertigbearbeitung von Werkstücken, insbesondere für das Polieren, von Werkstücken mit unregelmäßig geformter Oberfläche, mit einer Trommel mit magnetischen Einrichtungen, in welcher die Werkstücke durch ein ferromagnetisches Schleifmittel bearbeitet werden, wobei die Trommel einen Arbeitsbereich in der Form eines Ringkörpers hat, der von einem Boden und zylindrischen, am Boden befestigten Wänden umgeben ist, und mit einer Einrichtung zum Halten und Bewegen des Werkstücks.The invention relates to a machine for the finishing of workpieces, in particular for polishing, workpieces with an irregularly shaped surface, with a drum with magnetic devices in which the workpieces are processed by a ferromagnetic abrasive, the drum having a work area in the form of a Has annular body, which is surrounded by a bottom and cylindrical walls attached to the bottom, and with a device for holding and moving the workpiece.

Bei einer solchen, aus der DE-A-2 818 667 bekannten Maschine wird das Werkstück in einem kreisringförmigen Luftspalt eines feststehenden Elektromagneten längs des Luftspaltes bewegt, dabei um seine eigene Achse gedreht und gleichzeitig durch eine komplizierte mechanische Vorrichtung axial in Oszillationen versetzt, um ein möglichst gleichmäßiges Polieren des Werkstückes zu erreichen.In such a machine, known from DE-A-2 818 667, the workpiece is moved in a circular air gap of a fixed electromagnet along the air gap, being rotated about its own axis and at the same time axially oscillated by a complicated mechanical device to a to achieve as uniform polishing of the workpiece as possible.

Ein Nachteil dieser bekannten Maschine besteht jedoch darin, daß beim Polieren von Werkstücken mit unregelmäßigem Profil unerwünschterweise alle Kanten abgerundet werden.A disadvantage of this known machine, however, is that when polishing workpieces with an irregular profile, all edges are undesirably rounded.

Der Erfindung liegt deshalb die Aufgabe zugrunde, die Maschine der eingangs genannten Art so auszubilden, daß auch bei Werkstücken mit unregelmäßigem Profil alle Oberflächen gleichmäßig bearbeitet werden können.The invention is therefore based on the object to design the machine of the type mentioned in such a way that all surfaces can be machined evenly in the case of workpieces with an irregular profile.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Trommel drehbar ist, daß der Arbeitsbereich der Trommel oben durch einen relativ zur Trommel unbeweglichen Magneten abgeschlossen ist, daß sich im Zentrum des Arbeitsbereichs eine elektromagnetische Spule und eine Scheibe befinden, die mit einer starren Achse an dem Magneten befestigt sind, daß die zylindrischen Wände des Arbeitsbereichs aus nicht-ferromagnetischem Werkstoff bestehen und daß der Boden, die Achse und die Scheibe aus ferromagnetischem Werkstoff hergestellt sind.This object is achieved in that the drum is rotatable, that the working area of the drum is closed at the top by a magnet that is immovable relative to the drum, that there is an electromagnetic coil and a disc in the center of the working area, which have a rigid axis on the Magnets are attached that the cylindrical walls of the work area are made of non-ferromagnetic material and that the bottom, the axis and the disc are made of ferromagnetic material.

Vorteilhafterweise ist der Boden der Trommel mit einem Flansch an der starren Achse gelagert.The bottom of the drum is advantageously mounted with a flange on the rigid axle.

Vorzugsweise sind die Werkstücke an Spindeln in Arbeitsstationen befestigt, durch pneumatische Zylinder senkrecht bewegbar und durch Elektromotoren und Untersetzungsgetriebe drehbar.The workpieces are preferably fastened to spindles in workstations, vertically movable by pneumatic cylinders and rotatable by electric motors and reduction gears.

Zweckmäßigerweise wird der obere Magnet der Trommel zusammen mit den Arbeitsstationen durch eine Scheibe mit Nocken und Teilungsrad schrittweise gedreht, wobei sich die Arbeitsstationen in der unteren Stellung befinden und nur in der der ersten Arbeitsstation entsprechenden Position durch den pneumatischen Zylinder angehoben sind.The upper magnet of the drum together with the work stations is expediently rotated step by step by means of a disc with cam and dividing wheel, the work stations being in the lower position and only being raised by the pneumatic cylinder in the position corresponding to the first work station.

Die Maschine für die Fertigbearbeitung von Werkstücken mit unregelmäßigem Profil kann zum Beispiel sechs Arbeitsstationen aufweisen, die oberhalb des Arbeitsbereichs der 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 an irregular profile can have, for example, six work stations which are arranged above the working area of the drum, which has a lower, rapidly rotating magnetic pole. Each work station is equipped with an electric motor, reduction gear and a spindle to which a chuck is attached for clamping the workpiece. 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 unregelmäßigem 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 in der Form eines Ringkörpers, der von einem Boden 6 und zylindrischen Wänden 7 umgeben und oben von einem unbeweglichen Magneten 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 Magneten 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 an irregular profile consists of a drum 1, which is driven by an electric motor 3 via a belt drive 2. The drum 1 is mounted in a housing 4 and has a working area 5 in the form of an annular body which is surrounded by a base 6 and cylindrical walls 7 and is closed at the top by an immovable magnet 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 magnet 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 :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. Are 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:

Der Arbeitsbereich 5 wird mit einer ferromagnetischen Schleifmittelmischung gefüllt. Danach werden durch die Einrichtung 18 für den orientierten Vorschub Werkstücke der Zangenvorrichtung 17 zugeführt. Durch Betätigung des Manipulators bewegen sich seine Greifer aufwärts, wonach sie durch die Zangenvorrichtung 17 über den 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 derferromagnetischen 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 work area 5 is filled with a ferromagnetic mixture of abrasives. Then workpieces are fed to the pliers device 17 by the device 18 for the oriented feed. When the manipulator is actuated, its grippers move upwards, after which they are pivoted by the forceps device 17 over the 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 devices 17 until the workpieces are immersed in the ferromagnetic abrasive mixture which fills the working 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 processing 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.
