Abstract

The invention relates to a polishing head for a polishing machine, especially for polishing optical surfaces. The inventive polishing head comprises a polishing plate that is linked with a rotation-driven primary shaft. Said polishing plate (7) is hinged on the primary shaft (7) so as not to rotate. The hinged, rotationally fixed connection can be established by means of a hexagonal ball joint. Said hinged connection allows the polishing plate to rotate and simultaneously follow the surface (41) of the work piece (39) to be polished so that the polishing lining (5) always rests on the largest area possible of the surface (41).

Description

Polierkopf für eine PoliermaschinePolishing head for a polishing machine
Die Erfindung betrifft einen Polierkopf für eine Poliermaschine gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a polishing head for a polishing machine according to the preamble of patent claim 1.
Aus der EP 727 280 Bl ist eine Poliermaschine zum Polieren sphärischer Linsenoberflächen bekannt. Diese Poliermaschine weist einen oberen in einer x-Richtung verfahrbaren Schlitten auf. Mit diesem Schlitten ist eine Werkzeugspindel, die um eine vertikale Achse drehbar gelagert ist, verbunden. Die Werkzeugspindel dient dabei zur Aufnahme eines Abrichtwerkzeuges. Zur Aufnahme des Werkstückes bzw. der Linse ist eine mit einem weiteren Schlitten verbundene Werkstückspindel vorgesehen. Die Werkstückspindel und die Werkzeugspindel mit dem Abrichtwerkzeug sind in einem festen Abstand zueinander angeordnet. Der diese beiden Spindeln tragende Schlitten ist in z-Richtung verfahrbar.A polishing machine for polishing spherical lens surfaces is known from EP 727 280 B1. This polishing machine has an upper carriage which can be moved in an x direction. A tool spindle, which is rotatably mounted about a vertical axis, is connected to this slide. The tool spindle is used to hold a dressing tool. A workpiece spindle connected to a further slide is provided for receiving the workpiece or the lens. The workpiece spindle and the tool spindle with the dressing tool are arranged at a fixed distance from one another. The carriage carrying these two spindles can be moved in the z direction.
Aus der WO 97/00155 ist eine Poliermaschine und ein Verfahren zum Polieren von optischen Flächen bekannt. Die Poliermaschine weist einen Polierkopf auf, der mit einer elastischen Membran versehen ist. Durch Druckbeaufschlagung der Membran wird die Kraftbeaufschlagung der zu polierenden Fläche geregelt. Nachteilig ist bei dieser Polieraiaschine, daß die Größe der auf der zu polierenden Fläche aufliegende Fläche des Polierkopfes bzw. der Membran von der Druckbeaufschlagung abhängt. Der Polierkopf mit der elastischen Membran wird durch eine zugeordnete Feder in Richtung der zu polierenden Fläche vorgespannt. Für die Bereitstellung einer Kippbeweglichkeitder elastischen Membran ,um eine auf der Drehachse im Bereich der flexiblen Membran liegenden Punkt, sind Hydraulikzylinder vorgesehen. Die Kraftbeaufschlagung der zu polierenden Fläche wird durch zugeordnete Sensoren, Dehnstreifen und Solenoit, detektiert.A polishing machine and a method for polishing optical surfaces are known from WO 97/00155. The polishing machine has a polishing head which is provided with an elastic membrane. The force applied to the surface to be polished is regulated by pressurizing the membrane. A disadvantage of this polishing machine is that the size of the surface of the polishing head or the membrane resting on the surface to be polished depends on the pressurization. The polishing head with the elastic membrane is biased by an associated spring in the direction of the surface to be polished. Hydraulic cylinders are provided to provide the elastic membrane with tiltability about a point on the axis of rotation in the area of the flexible membrane. The application of force to the surface to be polished is detected by assigned sensors, stretch marks and solenoite.
In dem aus dieser Schrift bekannten Verfahren wird das Polieren der optischen Oberfläche in Abhängigkeit von der Drehzahl des polierenden Kopfes und der auf die zu polierende Oberfläche wirkenden Anpreßkraft durch Druckbeaufschlagung gesteuert. Es ist Aufgabe der Erfindung einen Polierkopf zum Polieren einer Freiformfläche bereitzustellen, durch den eine qualitativ hochwertige optische Oberfläche polierbar ist und durch dessen Einsatz ein konstanter Polierabtrag auf der gesamten zu polierenden optischen Oberfläche gewährleistet werden kann.In the method known from this document, the polishing of the optical surface is controlled as a function of the rotational speed of the polishing head and the contact pressure acting on the surface to be polished by applying pressure. It is an object of the invention to provide a polishing head for polishing a free-form surface, by means of which a high-quality optical surface can be polished and the use of which ensures constant polishing removal on the entire optical surface to be polished.
Die Aufgabe der Erfindung wird durch die im Patentanspruch 1 gegebenen Merkmale gelöst.The object of the invention is achieved by the features given in claim 1.
Durch die Maßnahme den Polierteller drehfest gelenkig mit der Antriebswelle zu verbinden ist es möglich, daß der Polierteller der Oberflächenkontur folgend auf der zu bearbeitenden Oberfläche aufliegt. Durch die gelenkige Verbindung kann der Polierteller Kippbewegungen ausfuhren, so daß er mit einer maximalen Polierfläche auf der zu polierenden Oberfläche aufliegt.As a result of the measure to connect the polishing plate in a rotationally fixed manner to the drive shaft, it is possible for the polishing plate to rest on the surface to be machined, following the surface contour. The articulated connection enables the polishing plate to perform tilting movements so that it lies on the surface to be polished with a maximum polishing surface.
Zur Übertragung der Drehbewegung der Antriebswelle auf den Polierteller hat es sich als vorteilhaft herausgestellt, den Polierteller mit der Antriebswelle mittels Formschluß zu verbinden, so daß die Drehbewegung der Antriebswelle aufgrund des Formschlusses auf den Polierteller übertragen wird.To transmit the rotary movement of the drive shaft to the polishing plate, it has proven to be advantageous to connect the polishing plate to the drive shaft by means of a positive connection, so that the rotary movement of the drive shaft is transmitted to the polishing plate due to the positive connection.
Es hat sich als vorteilhaft herausgestellt für die drehfeste gelenkige Verbindung den Polierteller über ein Kugelimbusgelenk mit der Antriebswelle zu verbinden. Durch dieses Kugelimbusgelenk ist es möglich, den Drehpunkt, um den der Polierteller in beliebige Richtungen geschwenkt werden kann, möglichst nah an der zu polierenden Oberfläche des Poliertellers anzuordnen. Die nahe Anordnung der gelenkigen Verbindung zur polierenden Oberfläche des Poliertellers hat den Vorteil, daß der Polierteller den Oberflächenkonturen reaktionsschnell folgen kann.It has been found to be advantageous for the non-rotatable articulated connection to connect the polishing plate to the drive shaft via a ball socket joint. This spherical imbus joint makes it possible to arrange the pivot point about which the polishing plate can be pivoted in any direction as close as possible to the surface of the polishing plate to be polished. The close arrangement of the articulated connection to the polishing surface of the polishing plate has the advantage that the polishing plate can follow the surface contours quickly.
Es hat sich als vorteilhaft herausgestellt der gelenkigen Verbindung ein oder mehrere Rastelement zur Sicherung der Verbindung von Antriebswelle und Polierkopf zuzuordnen. Ist als gelenkige Verbindung ein Kugelimbusgelenk vorgesehen, so wird mittels des Rastelementes sichergestellt, daß der Kugelimbuskopf aus der zugeordneten Ausnehmung nicht herausrutschen kann. Dadurch kann der Polierteller ohne Probleme von der zu polierenden Fläche entfernt werden. Durch die durch das Rastelement gewährleistete Lösbarkeit der Verbindung können außerdem verschiedene Polierteller leicht gegeneinander ausgetauscht werden.It has proven to be advantageous to associate the articulated connection with one or more locking elements for securing the connection between the drive shaft and the polishing head. If a spherical imbus joint is provided as an articulated connection, then the locking element ensures that the spherical imbus head cannot slip out of the assigned recess. This allows the polishing plate to move from the to without any problems polished surface to be removed. Due to the detachability of the connection guaranteed by the latching element, different polishing plates can also be easily exchanged for one another.
Es hat sich als vorteilhaft herausgestellt dem Polierkopf eine Druckkammer zuzuordnen wobei aus einer Druckbeaufschlagung der Druckkammer eine translatorische Bewegung des Poliertellers entlang einer Mittenachse des Polierkopfes resultiert. Liegt der Polierteller auf einer zu polierenden Oberfläche auf, so resultiert aus einer Druckbeaufschlagung ein erhöhter Polierdruck.It has been found to be advantageous to assign a pressure chamber to the polishing head, a translational movement of the polishing plate along a central axis of the polishing head resulting from pressurizing the pressure chamber. If the polishing plate lies on a surface to be polished, an increased polishing pressure results from pressurization.
Es hat sich als vorteilhaft herausgestellt, wenn ein der Druckkammer zugeordneter Kolben mit der Antriebswelle in Wirkverbindung steht, so daß eine Druckbeaufschlagung der Druckkammer über die Antriebswelle auf den Polierteller übertragen wird.It has proven to be advantageous if a piston assigned to the pressure chamber is operatively connected to the drive shaft so that pressurization of the pressure chamber is transmitted to the polishing plate via the drive shaft.
Es hat sich als vorteilhaft herausgestellt die Antriebswelle mittels eines koaxial angeordneten Hohlzylinders, in dem die Antriebswelle drehfest gelagert ist, über diesen Hohlzylinder anzutreiben. Für die Übertragung der Drehbewegung hat sich eine formschlüssige Verbindung als vorteilhaft erwiesen.It has proven to be advantageous to drive the drive shaft by means of a coaxially arranged hollow cylinder, in which the drive shaft is rotatably mounted, via this hollow cylinder. A positive connection has proven to be advantageous for the transmission of the rotary movement.
Es hat sich als vorteilhaft herausgestellt, die Antriebswelle in dem Hohlzylinder mittels Lagerelementen z.B. einer Wälzlagerung oder einer Kugellagerung translatorisch leicht bewegbar zu lagern. Durch diese Lagerung wird gewährleistet, daß bei Druckbeaufschlagung der Druckkammer sich die Antriebswelle in dem Hohlzylinder leichtgängig translatorisch bewegen kann und somit die eingeleitete translatorische Bewegung bzw. Kraftbeaufschlagung nahezu vollständig auf den Polierteller übertragen wird.It has proven to be advantageous to drive the drive shaft in the hollow cylinder by means of bearing elements e.g. a roller bearing or a ball bearing to be easily movable in translation. This mounting ensures that when the pressure chamber is pressurized, the drive shaft can move translationally smoothly in the hollow cylinder and thus the translational movement or force applied is almost completely transmitted to the polishing plate.
Weitere vorteilhafte Maßnahmen sind in weiteren abhängigen Ansprüchen beschrieben.Further advantageous measures are described in further dependent claims.
Anhand eines Ausführungsbeispieles wird die Erfindung im folgenden näher beschrieben.The invention is described in more detail below using an exemplary embodiment.
Es zeigt: Figur 1 eine schematische Skizze des Polierkopfes in einem dessen Mittenachse enthaltenen Schnittes;It shows: Figure 1 is a schematic sketch of the polishing head in a section containing the central axis;
Figur 2 einen Schnitt entlang der Ebene FI - II in Figur 1 ;FIG. 2 shows a section along the plane FI-II in FIG. 1;
Figur 3 einen Schnitt entlang der Ebene III - III in Figur 1 ; und3 shows a section along the plane III-III in FIG. 1; and
Figur 4 Schnitt entlang der Ebene III - III bei einem alternativen Ausfuhrungsbeispiel.Figure 4 section along the plane III - III in an alternative embodiment.
Der in Figur 1 dargestellte Polierkopf (1) weist einen Polierteller (3) mit einem Polierbelag (5) auf. Der Polierbelag (5) liegt auf einer zu polierenden Oberfläche (41) eines Werkstückes (39) auf.The polishing head (1) shown in FIG. 1 has a polishing plate (3) with a polishing pad (5). The polishing coating (5) rests on a surface (41) of a workpiece (39) to be polished.
Der Polierteller 3 ist über die gelenkige Verbindung an einer Antriebswelle (7) aufgenommen. Im dargestellten Ausfuhrungsbeispiel ist für diese drehfeste gelenkige Verbindung ein Kugelimbusgelenk vorgesehen. Die Antriebswelle (7) ist dazu auf der dem Polierteller zugewandten Seite endseitig mit einem Kugelimbuskopf (19) versehen, der in eine im Polierteller (3) ausgebildete Ausnehmung (13) eingreift.The polishing plate 3 is received on the drive shaft (7) via the articulated connection. In the exemplary embodiment shown, a spherical socket joint is provided for this non-rotatable articulated connection. For this purpose, the drive shaft (7) is provided on the end facing the polishing plate with a spherical imbus head (19) which engages in a recess (13) formed in the polishing plate (3).
Zur Sicherung ist die Verbindung zwischen dem Kugelimbuskopf (19) und dem Polierteller (3) mittels eines Rastelementes (15) gesichert ist. Als Rastelement können beispielsweise ein Federelement bzw. Federstift am Polierteller, der in eine Ausnehmung am Kugelimbuskopf hinein ragt, vorgesehen sein.To secure the connection between the ball socket head (19) and the polishing plate (3) is secured by means of a locking element (15). For example, a spring element or spring pin on the polishing plate, which projects into a recess on the ball socket head, can be provided as the latching element.
Es ist auch möglich, den Kugelimbuskopf (19) an dem Polierteller auszubilden; in diesem Fall ist dann in der Antriebswelle (7) eine Ausnehmung zur drehsicheren gelenkigen Aufnahme des Kugelimbuskopfes vorzusehen. Allerdings ist in diesem Fall der Abstand zwischen der Gelenkstelle - also dem Punkt, um den eine Kippung des Poliertellers relativ zur starren Antriebswelle erfolgen kann - und der zu polierenden Fläche (41) größer. Die Antriebswelle (7) ist über Lagerelement (23) translatorisch verschiebbar und drehfest in einem Hohlzylinder (49) gelagert. Der Hohlzylinder (49) wird rotatorisch angetrieben über einen nicht dargestellten Antrieb der Poliermaschine, wobei die Drehbewegung aufgrund der drehfesten Verbindung durch das Lagerelement (23) vollständig auf die Antriebswelle (7) für den Polierkopf übertragen wird.It is also possible to form the spherical imbus head (19) on the polishing plate; in this case, a recess must be provided in the drive shaft (7) for the rotatable, articulated receptacle of the spherical imbus head. In this case, however, the distance between the articulation point - ie the point around which the polishing plate can be tilted relative to the rigid drive shaft - and the surface (41) to be polished is larger. The drive shaft (7) is translationally displaceable via bearing element (23) and is mounted in a hollow cylinder (49) in a rotationally fixed manner. The hollow cylinder (49) is driven in rotation by a drive (not shown) of the polishing machine, the rotary movement being completely transmitted to the drive shaft (7) for the polishing head due to the rotationally fixed connection by the bearing element (23).
Auf der vom Polierkopf abgewandten Seite der Antriebswelle (7) ist in dem Hohlzylinder (49) ein Hydraulik- oder Pneumatiksystem, das zur Beaufschlagung des Polierkopfes mit dem erforderlichen Polierdruck dient, vorgesehen. Dieses weist einen Druckkammerzylinder (31) mit einem darin translatorisch verschiebar aufgenommenen Kolben (33) auf. Zur Entkoppelung des Kolbens (33) von der Drehbewegung der Antriebswelle (7) und des Hohlzylinders können Drehlager zwischen dem Druckkammerzylinder (31) und dem Hohlzylinder (49) sowie zwischen dem vom Kolben (33) angetriebenen Pleul (32) und der Antriebswelle (7) vorgesehen sein. Zur Druckbeaufschlagung des Kolbens (33) ist der im Druckkammerzylinder (31) gebildeten Druckkammer (29) eine Druckversorgung (35) mit einem Druckregel ventil (37) und einem Druckreservoir (36) zugeordnet. Durch Druckbeaufschlagung der Druckkammer (29) wird eine entlang einer Mittenachse (2) des Polierkopfes (1) gerichteten Kraft auf den Kolben (33) eingeleitet. Aus dieser Kraft resultiert eine translatorische Bewegung des Poliertellers bzw. eine Erhöhung der wirkenden Polierkraft, sofern der Polierbelag (5)auf einer zu polierenden optischen Fläche (41) eines Werkstückes (39) aufliegt.On the side of the drive shaft (7) facing away from the polishing head, a hydraulic or pneumatic system is provided in the hollow cylinder (49) which serves to apply the required polishing pressure to the polishing head. It has a pressure chamber cylinder (31) with a piston (33) which is accommodated in a translationally displaceable manner. To decouple the piston (33) from the rotary movement of the drive shaft (7) and the hollow cylinder, rotary bearings can be arranged between the pressure chamber cylinder (31) and the hollow cylinder (49) and between the connecting rod (32) driven by the piston (33) and the drive shaft (7 ) be provided. For pressurizing the piston (33), the pressure chamber (29) formed in the pressure chamber cylinder (31) is assigned a pressure supply (35) with a pressure control valve (37) and a pressure reservoir (36). By pressurizing the pressure chamber (29), a force directed along a central axis (2) of the polishing head (1) is applied to the piston (33). This force results in a translatory movement of the polishing plate or an increase in the effective polishing force if the polishing layer (5) rests on an optical surface (41) of a workpiece (39) to be polished.
Die drehfeste translatorisch bewegbare Kopplung zwischen dem Hohlzylinder (49) und der Antriebswelle (7) erfolgt über ein Wälzlager (23). Die Antriebswelle (7) weist dazu ein nicht rotationssymmetrisches Außenprofil (43), vorzugsweise ein Mehrkantprofil auf. Der Formschluß zwischen dem Außenprofil (43) der Antriebswelle (7) und der Innenwand des Hohlzylinders wird über Rollen oder Walzen (25) erreicht, die in dem Lagerelement (23) symmetrisch zum Außenprofil der Antriebswelle (7) aufgenommen sind und an dem Außenprofϊl (43) der Antriebswelle abrollen. Die Drehachsen der Rollen oder Walzen sind dabei senkrecht zur Rotationachse der Antriebswelle (7) ausgerichtet. Anstelle der Wälzlagerung der Antriebswelle (7) in dem Hohlzylinder (49) kann auch eine Kugellagerung, wie in Figur 4 dargestellt, vorgesehen sein. Zur drehfesten translatorisch verschiebbaren Verbindung sind die Kugeln (53) in Längsnuten (51) des Hohlzylinders (49) und weiteren Längsnuten (55) der Antriebswelle (7) gelagert, wobei sich die Längsnuten parallel zur Rotationsachse der Antriebswelle (7) erstrecken. Auch in diesem Fall weist die Antriebsachse wenigstens in einem der Lagerung entsprechenden Bereich ein nicht- rotationssysmmetrisches Außenprofil, insbesondere ein Mehrkantprofil auf.The rotationally fixed, translationally movable coupling between the hollow cylinder (49) and the drive shaft (7) takes place via a roller bearing (23). For this purpose, the drive shaft (7) has a non-rotationally symmetrical outer profile (43), preferably a polygonal profile. The positive connection between the outer profile (43) of the drive shaft (7) and the inner wall of the hollow cylinder is achieved via rollers or rollers (25) which are accommodated in the bearing element (23) symmetrically to the outer profile of the drive shaft (7) and on the outer profile ( 43) roll off the drive shaft. The axes of rotation of the rollers or rollers are aligned perpendicular to the axis of rotation of the drive shaft (7). Instead of the roller bearing of the drive shaft (7) in the hollow cylinder (49), a ball bearing, as shown in FIG. 4, can also be provided. The balls (53) are mounted in the longitudinal grooves (51) of the hollow cylinder (49) and further longitudinal grooves (55) of the drive shaft (7) for the rotationally fixed translationally movable connection, the longitudinal grooves extending parallel to the axis of rotation of the drive shaft (7). In this case too, the drive axle has a non-rotationally symmetrical outer profile, in particular a polygonal profile, at least in a region corresponding to the bearing.
Im folgenden wird das Polierverfahren näher beschrieben. Zum Polieren wird der Polierkopf, dessen Durchmesser kleiner ist als der Durchmesser der zu polierenden Fläche, in einer Schwenkbewegung in radialer Richtung über die zu polierende optische Fläche (41) bewegt. Sowohl das Werkstück (39) als auch der Polierteller werden dabei mit nahezu gleicher Drehzahl in identischer Richtung angetrieben. Bei Bewegung des Poliertellers über die zu polierende optische Fläche (41) kann vorgesehen sein, daß die Drehzahlen des Poliertellers oder die Drehzahl des Werkstückes, insbesondere in Abhängigkeit von der radialen Position des Poliertellers, zu verändern. Diese Drehzahländerung hat einen positiven Einfluß auf einen konstanten Polierabtrag.The polishing process is described in more detail below. For polishing, the polishing head, whose diameter is smaller than the diameter of the surface to be polished, is moved in a pivoting movement in the radial direction over the optical surface (41) to be polished. Both the workpiece (39) and the polishing plate are driven at almost the same speed in the same direction. When the polishing plate is moved over the optical surface (41) to be polished, it can be provided that the rotational speed of the polishing plate or the speed of the workpiece is changed, in particular as a function of the radial position of the polishing plate. This change in speed has a positive influence on a constant polishing removal.
Durch die Wahl eines sehr großen Speichervolumens (36) im Verhältnis zum sich verändernden Volumen des Kolbens (31), werden die Druckschwankungen sehr klein gehalten, so daß der Polierteller mit konstanter Kraft auf der zu polierenden optischen Fläche aufliegt. Das Druckregelventil trägt auch noch zum Ausgleich von Druckschwankungen bei.By choosing a very large storage volume (36) in relation to the changing volume of the piston (31), the pressure fluctuations are kept very small, so that the polishing plate rests with constant force on the optical surface to be polished. The pressure control valve also helps to compensate for pressure fluctuations.
Durch die beschriebene Anordnung in Verbindung mit einer Poliermaschine nach dem Stand der Technik sind insbesondere nicht rotationssymmetrische optische Oberflächen (41) polierbar, wobei der Polierabtrag über die gesamte optische Fläche konstant ist. Für den gleichmäßigen Polierabtrag ist es erforderlich, daß der Polierbelag des Poliertellers (3) möglichst großflächig auf der zu polierenden optischen Fläche (41) aufliegt. Dies wird insbesondere dadurch gewährleistet, daß durch die drehfeste gelenkige Verbindung zwischen dem Polierteller und der Antriebswelle (7) der Polierteller um einen auf der Mittenachse (2) des Polierkopfes liegenden Punkt in beliebige Richtungen gekippt werden kann und die Ausrichtung des Poliertellers dadurch der Oberflächenkontur der zu polierenden Fläche (41) folgen kann. The arrangement described in connection with a polishing machine according to the prior art makes it possible, in particular, to polish non-rotationally symmetrical optical surfaces (41), the polishing removal being constant over the entire optical surface. For uniform polishing removal, it is necessary that the polishing surface of the polishing plate (3) rests on the optical surface (41) to be polished over as large a surface as possible. This is ensured in particular by the fact that the non-rotatable articulated connection between the polishing plate and the drive shaft (7) allows the polishing plate to be tilted in any direction about a point on the center axis (2) of the polishing head and that Alignment of the polishing plate can follow the surface contour of the surface to be polished (41).
