Abstract

The arrangement consists of a shaft at the end of which a polishing stone is mounted. The shaft is supported at an angle in self aligning bearings. The self aligning bearings are mounted eccentrically in a cylinder which itself is supported on ball bearings. The cylinder is rotated by a slotted plate. The slot of this plate engages with the end of the shaft with polishing stone so that the cylinder is rotated, and the shaft with stone is oscillated. The centre line of the curved surface generated, will lie on the interaction point of the centre lines of shaft and cylinder.

Description

Vorrichtung zur Erzeugung von Schwingbewegungen für die Superfinishbearbeitung Die Erfindung betrifft eine mechanische Vorrichtung zur Erzeugung von Schwingbewegungen für die Superfinishbearbeitung, insbesondere von balligen Innen- und Außenflächen, aber auch von Planflächen.Device for generating oscillating movements for superfinishing The invention relates to a mechanical device for generating oscillating movements for superfinishing, especially of spherical inner and outer surfaces, but also of planar surfaces.

Die Superfinishbearbeitung balligen Flächen wird zegenwärtig mittels eines Schwenkarmes durchgeführt. Die Schwingbewegung des Honsteines wird üblicherweise von Exzentern Über ein Kurbelgetriebe abgeleitet. Eine derartige Vorrichtung ist verhältnismässig kompliziert. Innerhalb des Kurbelgetriebes kommt es häufig zu starkem Lagerverschleiß, wobei das in diesem Mechanismus entstehende Lagerspiel eine lästige Geräuschquelle darstellt. Ein weiterer Nachteil ist die große Masse der Schwingvorrichtung, was sich namentlich bei der Fertigbearbeitung von balligen Flächen mit grösseren Halbmessern bemerkbar macht. Die den Schwenkarm aufweisenden Superfinisheinrichtungen sind lediglich für einen einzigen Durchmesser der balligen Fläche bestimmt oder sie sind nur für kleinere Durchmesserbereiche einstellbar.The superfinishing of spherical surfaces is currently carried out using carried out by a swivel arm. The oscillating movement of the honing stone is usually Derived from eccentrics via a crank gear. Such a one contraption is relatively complicated. It happens frequently within the crank mechanism excessive bearing wear, whereby the bearing play that occurs in this mechanism represents an annoying source of noise. Another disadvantage is the large size the oscillating device, which is particularly evident in the finishing of spherical Makes areas with larger radius noticeable. The ones having the swivel arm Superfinishing devices are only for a single diameter of the crowned Area determined or they can only be adjusted for smaller diameter ranges.

Die Aufgabe der Erfindung ist es, eine Schwingvorrichtung zu schaffen, die es ermöglicht, eine kreisförmige Schwingbewegung mit kontinuierlich einstellbarem Halbmesser verschiedener Grössen hervorzurufen.The object of the invention is to create a vibrating device, which makes it possible to have a circular oscillating movement with continuously adjustable To produce radiuses of different sizes.

Die Erfindung geht aus von einer Vorrichtung, die aus einem Körper besteht, in welchem drehbar ein Rotor angeordnet ist, durch welchen mit entsprechendem Spiel eine Welle geführt ist, an derem Ende gemeinsam mit einem Anpreßmechanismus, beispielsweise einem hydraulischen Mechanismus, der Honstein untergebracht ist.The invention is based on a device that consists of a body consists, in which a rotor is rotatably arranged, through which with a corresponding Game a shaft is guided, at the end of which together with a pressure mechanism, for example a hydraulic mechanism that houses the honing stone.

Das Wesen der Erfindung besteht darin, daß an den beiden Stirnseiten des Rotors verstellbar Pendellageraufnahmen für die Welle des Honsteines angeordnet sind. Diese Welle ist mit einem Glied, z.B. mit einem Kreuzsupport gekoppelt, welcher die Drehung der Welle verhindert.The essence of the invention is that on the two end faces of the rotor adjustable self-aligning bearing mounts for the shaft of the honing stone are. This shaft is coupled with a link, e.g. with a cross support, which prevents the shaft from rotating.

Bei der beschriebenen Vorrichtung kann die Schwingbreite im Bereich von Null bis zum Maximum der Exzentrizität kontinuierlich eingestellt werden. Die Vorrichtung ist insbesondere für die Fertigbearbeitung der Funktionsflächen von Wälziagerteilen anwendbar, die in einer anderen deutschen Patentanmeldung beschrieben wurde. Die Vorrichtung kann, zum Unterschied von den bisher bekannten Schwingvorrichtungen, mit höherer Frequenz arbeiten.In the case of the device described, the amplitude can be in the range can be continuously adjusted from zero to the maximum of the eccentricity. the Device is particularly useful for finishing the functional surfaces of Roller bearing parts applicable, which are described in another German patent application became. The device can, in contrast to the previously known vibrating devices, work at a higher frequency.

Das Wesender Erfindung ist nachstehend anhand eines in der Zeichnung schematisch dargestellten Ausführungsbeispieles näher#erläutert. In der Zeichnung ist die erfindungsgemässe Vorrichtung für die Fertigbearbeitung von balligen Flächen dargestellt.The essence of the invention is shown below with reference to one in the drawing schematically illustrated embodiment example explained in more detail. In the drawing is the device according to the invention for the finishing of spherical surfaces shown.

Die Vorrichtung besteht aus einem Gehäuse 1 mit WSlzlagern -2, in welchen ein Rotor 3 gelagert ist. Durch diesen Rotor ist-für diesen Fall ein exzentrisches Loch durchgeführt. Durch dieses Loch erstreckt sich die Welle 4, deren Achse mit der Achse des Rotors den Winkel a einschliesst. Die Welle 4 ist in den Lagern 5 gelagert, welche in den Aufnahmen 6 verstellbar untergebracht sind, und zwar mittels Auflageplatten, die an den Stirnflächen des Rotors 3 befestigt sind. Durch Verstellung der Aufnahme 6 kann einerseits die Exzentrizität e und andererseits der von der Achse Ol des Rotors 3 und der Achse O der Welle 4 eingeschlossene Winkel a kontinuierlich geändert werden. An der Welle 4 ist der hydraulische Zylinder 7 angebracht, mit welchem der Honstein in Schnittrichtung zugestellt wird. Auf dem entgegengesetzten Ende der Welle 4 ist auf dem Gestell der Vorrichtung der Kreuzsupport 9 befestigt, welcher die Drehung der Welle 4 verhindert. Am Rotor 3 befindet sich eine Riemenscheibe lo, welche zur Übertragung der Drehbewegung vom Antriebsmotor dient.The device consists of a housing 1 with WSlzlagern -2, in which a rotor 3 is mounted. This rotor is an eccentric one in this case Hole carried out. The shaft 4 extends through this hole, along with its axis the axis of the rotor includes the angle a. The shaft 4 is in the bearings 5 stored, which are housed adjustable in the receptacles 6, by means of Support plates on the end faces of the rotor 3 are attached. By adjusting the receptacle 6 on the one hand the eccentricity e and on the other hand the angle enclosed by the axis O1 of the rotor 3 and the axis O of the shaft 4 a can be changed continuously. The hydraulic cylinder 7 is on the shaft 4 attached, with which the honing stone is fed in the cutting direction. On the opposite end of the shaft 4 is on the frame of the device of the cross support 9 fixed, which prevents the rotation of the shaft 4. On the rotor 3 is located a pulley lo, which is used to transmit the rotary motion from the drive motor serves.

Die Vorrichtung arbeitet folgendermaßen: Nachdem das zu bearbeitende Werkstück derart zugestellt worden ist, daß der Schnittpunkt der Achse Ol des Rotors 3 und der Achse O der Welle 4 mit dem Mittelpunkt der zu bearbeitenden Kugel identisch ist, wird durch Verstellung der Aufnahmen 6 die Exzentrizität e bei gleichzeitiger Einstellung des Winkels a eingestellt. Durch die Wirkung des hydraulischen Zylinders 7 sitzt der Honstein auf der bearbeiteten balligen Fläche auf. Mittels der Riemenscheibe lo dreht sich der Rotor 3, wobei die Welle 4 eine Präzessionsbewegung um die Achse Ol des Rotors 3 ausübt, welche mit der Achse 0 der Welle 4 im Mittelpunkt der zu bearbeitenden balligen Fläche zusammenfällt. Auf diese Weise vollführt der Honstein 8 auf der zu bearbeitenden Fläche eine kreisende Bewegung.The device works as follows: After that to be processed Workpiece has been fed in such a way that the intersection of the axis Ol of the rotor 3 and the axis O of the shaft 4 are identical to the center of the ball to be machined is, by adjusting the recordings 6, the eccentricity e with simultaneous Setting of the angle a set. By the action of the hydraulic cylinder 7 the honing stone sits on the machined crowned surface. By means of the pulley The rotor 3 rotates, with the shaft 4 making a precession movement about the axis Oil of the rotor 3 exerts, which with the axis 0 of the shaft 4 in the center of the to processed crowned surface coincides. This is how the honing stone performs 8 a circular motion on the surface to be processed.

Bei Anwendung einer modifizierten Vorrichtung zum Andrücken des Honsteines kann die Vorrichtung auch für die Superfinishbearbeitung von Kugellagerlaufbahnen verwendet werden. Wenn die Welle 4 derart eingestellt ist, daß die Achse Ol des Rotors 3 zur Achse 0 der Welle 4 parallel liegt, kann die Vorrichtung für die Bearbeitung von Planflächen angewandt werden.When using a modified device for pressing the honing stone the device can also be used for superfinishing ball bearing raceways be used. When the shaft 4 is set so that the axis Ol of the The rotor 3 is parallel to the axis 0 of the shaft 4, the device can be used for machining of planar surfaces can be used.
