Abstract
Description
Die Erfindung betrifft eine Planschleifmaschine für im Wesentlichen flache Werkstücke, die zum einen wenigstens eine Schleifspindel und ein insbesondere als eine weitere Spindel oder Schleifspindel ausgebildetes Gegenlager umfasst, wobei zumindest die Schleifspindel, und insbesondere auch die weitere Spindel, jeweils mit einer Planschleifscheibe zum Planschleifen von zumindest einem Werkstück versehen ist, und die zum anderen mit einer Kinematik, insbesondere Planetenkinematik, zur Erzielung einer Relativbewegung zwischen zumindest einem insbesondere in der Kinematik geführten Werkstück und der Drehachse der Schleifspindel (n) versehen ist. Eine Planschleifmaschine dieser Art ist z.B. aus der Druchschrift
Aus der Praxis sind derartige Planschleifmaschinen mit einer Planetenkinematik bekannt, bei denen die Werkstücke durch Planeten mit Masken zwischen zwei Planschleifscheiben geführt werden. Dabei werden hohe Anforderungen an die Formgenauigkeit der fertig geschliffenen Werkstücke gestellt.From practice, such surface grinding machines are known with a planetary kinematics, in which the workpieces are guided through planets with masks between two flat grinding wheels. High demands are placed on the dimensional accuracy of the finished ground workpieces.
Nachteilig hierbei ist, dass solche vorbekannten Planschleifmaschinen lediglich eine Weiterentwicklung von Läppmaschinen darstellen und konzeptbedingt den Anforderungen beim Schleifen in einer automatisierten Produktionsumgebung nicht gerecht werden können.The disadvantage here is that such prior art surface grinding machines represent only a further development of lapping and conceptually the requirements when grinding in an automated production environment can not meet.
Aufgabe der Erfindung ist es, die vorgenannten Nachteile zu vermeiden und eine Planschleifmaschine anzugeben, mit der flache Werkstücke mit überlagerter radialer Wirkbewegung ein- oder zweiseitig plan bzw. planparallel geschliffen werden können. Dabei soll die Planschleifmaschine insbesondere sowohl für Ein- oder Zweiseitenplanschleifen mit radialen Werkstückoszillationen als auch für das Ein- oder Zweiseitenplanschleifen mit zykloider Werkstückbewegung geeignet sein. Die Planschleifmaschine soll vorzugsweise innerhalb eines sehr kompakten Bauraums realisierbar sein und durch einen modularen Aufbau flexibel für verschiedene kinematische Konzepte einsetzbar sein.The object of the invention is to avoid the aforementioned disadvantages and to provide a surface grinding machine, with the flat workpieces with superimposed radial active movement one or two sides can be ground plan or plane-parallel. In this case, the surface grinding machine should be suitable in particular for one- or two-side surface grinding with radial workpiece oscillations as well as for one- or two-side surface grinding with cycloidal workpiece movement. The surface grinding machine should preferably be realized within a very compact space and be flexible by a modular structure for different kinematic concepts.
Diese Aufgabe wird dadurch gelöst, dass die Schleifspindel und das Gegenlager mit entsprechenden Führungen an zwei Säulenbereichen gelagert sind, die übereinander angeordnet und miteinander fluchtend und als Teile einer durchgehenden Säule, ausgebildet sind. Hierdurch ist eine besonders stabile und technisch eher nicht aufwändige Konstruktion für die Lagerung von Schleifspindel und Gegenlager gegeben, die je nach Ausprägung sowohl eine axiale als auch radiale Zustellung der Schleifspindel und/oder des Gegenlagers ermöglicht. Auch kann durch radiales Schwenken der Schleifspindel(n) ein Austausch der Planschleifscheiben und/oder eine Änderung der Kinematik leicht erfolgen, da ein einfaches Handling und insbesondere eine Verlagerung in eine Parkposition ohne erhöhten Kraftaufwand möglich ist.This object is achieved in that the grinding spindle and the abutment are mounted with corresponding guides on two pillar areas, which are arranged one above the other and aligned with each other and as parts of a continuous column formed. As a result, a particularly stable and technically rather complex design for the storage of grinding spindle and abutment is given, which allows both an axial and radial delivery of the grinding spindle and / or the abutment depending on the expression. Also, by radial pivoting of the grinding spindle (s) an exchange of flat grinding wheels and / or a change in the kinematics can be easily done, since a simple handling and in particular a shift to a parking position without increased effort is possible.
Dabei sind die Führungen der Schleifspindel und des Gegenlagers für eine rotatorische, insbesondere weggebundene, Zustellung ausgebildet, so dass durch die Führungen eine Drehachse gebildet wird. Bei weggebundener Zustellung ist eine hohe Zustellgenauigkeit gegeben.The guides of the grinding spindle and the counter bearing are for a rotary, in particular weggebundene, delivery formed so that an axis of rotation is formed by the guides. With tied delivery, a high delivery accuracy is given.
Auch kann eine Mehrfachnutzung der Achsen für die Zustellung und/oder die Oszillation und/oder einen Vorschub beim Abrichten bzw. Messen etc. erfolgen.Also, a multiple use of the axes for the delivery and / or the oscillation and / or a feed during dressing or measuring etc. take place.
Vorteilhafterweise kann das Gegenlager als eine Flanschaufnahme ohne Drehlagerung oder als eine ohne Drehlagerung ausgebildete Aufnahme für eine Werkstückaufnahme ausgebildet sein, so dass ein entsprechender Flansch bzw. eine entsprechend angepasste Werkstückaufnahme dort vorgesehen werden können.Advantageously, the abutment may be formed as a flange without pivot bearing or as a trained without pivot bearing receptacle for a workpiece holder, so that a corresponding flange or a correspondingly adapted workpiece holder can be provided there.
Erfindungsgemäß können die Schleifspindel und das als weitere Spindel oder Schleifspindel ausgebildete Gegenlager zumindest annähernd parallel ausgerichtete Drehachsen aufweisen, so dass bei entsprechender rotatorischer Bewegung der beiden Spindel planparallele Oberflächen der zu bearbeitenden Werkstücke erzielbar sind.According to the invention, the grinding spindle and the abutment designed as a further spindle or grinding spindle can have at least approximately parallel aligned axes of rotation, so that with a corresponding rotational movement of the two spindle plane-parallel surfaces of the workpieces to be machined can be achieved.
Verzugsweise kann die Planschleifmaschine einen modularen Aufbau haben und das Gegenlager als multifunktionale Spindelaufnahme ausgebildet sein, in der entweder ein Spindelkörper ohne Drehlagerung mit einer Flanschbefestigungseinrichtung für die Anbringung eines Flansches oder aber eine vollständige zweite Schleifspindel anbringbar ist, so dass eine hohe Flexibilität für verschiedenste Bearbeitungsschritte und/oder -verfahren gegeben ist.Preferably, the surface grinding machine can have a modular design and the abutment be designed as a multifunctional spindle receptacle in which either a spindle body without pivot bearing with a flange mounting means for attaching a flange or a complete second grinding spindle can be attached, so that a high degree of flexibility for a variety of processing steps and / or procedure is given.
Auch können die Führungen der Schleifspindel und des Gegenlagers für eine axiale, insbesondere weggebundene, Längszustellung ausgebildet sein, so dass durch die Führungen eine Linearachse gebildet wird. Bei weggebundener Zustellung ist eine hohe Zustellgenauigkeit gegeben und es werden kalkulierbare Abtragsraten auch bei verschiedener Schnittfreudigkeit der Planschleifscheiben gegenüber einer kraftgebundenen Zustellung erreicht.Also, the guides of the grinding spindle and the thrust bearing for an axial, in particular weggebundene, longitudinal feed can be formed so that a linear axis is formed by the guides. When weggebundener delivery high delivery accuracy is given and it calculable Abtragsraten be achieved even with different Schnittfreudigkeit the flat grinding wheels against a force-fed delivery.
Erfindungsgemäß können die Führungen der Schleifspindel und des Gegenlagers jeweils als hydrostatische Führungen ausgebildet sein, so dass durch die Führungen sowohl Drehachse als auch Linearachse gebildet sind, wobei hierdurch ein gutes Dämpfungsvermögen mit einer hohen Steifigkeit kombiniert ist.According to the invention, the guides of the grinding spindle and the anvil can each be designed as hydrostatic guides, so that both rotational axis and linear axis are formed by the guides, whereby a good damping capacity is combined with a high rigidity.
Bei einem bevorzugten Ausführungsbeispiel der Erfindung können die Führungen der Spindeln an der durchgehenden Säule übereinander greifend gelagert sein, wobei jeweils eine Führung der einen Spindel zwischen den beiden Führungen der anderen Spindel an der Säule gelagert ist, so dass durch eine größere Führungslänge eine besonders hohe Steifigkeit gegeben ist.In a preferred embodiment of the invention, the guides of the spindles on the continuous column can be mounted overlapping one another, wherein in each case a guide of a spindle between the two guides of the other spindle is mounted on the column, so that by a greater guide length a particularly high rigidity given is.
Vorteilhafterweise können an beiden Spindeln Planschleifscheiben vorgesehen sein, die übereinander angeordnet sind, so dass eine zweiseitige Bearbeitung der Werkstücke in einem Arbeitsstück möglich ist.Advantageously, surface grinding wheels can be provided on both spindles, which are arranged one above the other, so that a two-sided machining of the workpieces in a workpiece is possible.
Erfindungsgemäß kann zumindest eine Planschleifscheibe, insbesondere die obere Planschleifscheibe, vorzugsweise durch ein zwischen drehmomentsteifem Schleifscheibenflansch und Planschleifscheibe angeordnetes Zwischenelement mit variabler Steifigkeit, schwimmend, gelagert sein, so dass bei Schleifbeginn vorhandene unterschiedlich Höhen der in einem Arbeitsgang zu bearbeitenden verschiedenen Werkstücke kompensiert werden können. Alternativ kann jedoch auch eine starre Lagerung von zumindest einer insbesondere von beiden Planschleifscheiben, möglich sein.According to the invention, at least one flat grinding wheel, in particular the upper flat grinding wheel, can preferably be mounted floating by means of a variable rigidity intermediate element arranged between the torque-resistant grinding wheel flange and the flat grinding wheel, so that at the start of grinding existing different heights of the workpieces to be processed in a single work piece can be compensated. Alternatively, however, a rigid mounting of at least one in particular of both flat grinding wheels may be possible.
Auch kann zumindest eine Planschleifscheibe, insbesondere die obere Planschleifscheibe, bei schwimmender Lagerung gegen Verkippen feststellbar gelagert sein, so dass durch eine einstellbare Nachgiebigkeit die Steifigkeit während des Verlaufs des Schleifvorgangs anpassbar ist, so dass die Gefahr von sich aufbauenden Schwingungen reduziert werden kann und somit eine hohe Formgenauigkeit der Werkstücke durch eine kurz vor Erreichen des Werkmaßes dann parallel ausgebildeten Arbeitsspalt realisierbar ist. Dies kann beispielsweise durch eine Polymerlage, durch Federn mit einstellbarer Vorspannung oder durch Zylinder, insbesondere Hydraulikzylinder, mit einstellbarem Druck realisiert sein.Also, at least one face grinding wheel, in particular the upper face grinding disc, be mounted lockable against floating during storage, so that by an adjustable flexibility, the rigidity during the course of the grinding process is adjustable, so that the risk of self-building vibrations can be reduced and thus a high dimensional accuracy of the workpieces by a short before reaching the size of the work then parallel trained working gap can be realized. This can be realized, for example, by a polymer layer, by springs with adjustable pretension or by cylinders, in particular hydraulic cylinders, with adjustable pressure.
Vorzugsweise kann zumindest eine Planschleifscheibe, insbesondere die obere Planschleifscheibe, gegen rotatorisches Verdrehen feststellbar gelagert sein, so dass diese Planschleifscheibe wahlweise auch als nicht rotierende Auflagefläche einsetzbar ist.Preferably, at least one face grinding wheel, in particular the upper face grinding wheel, can be mounted lockable against rotational rotation, so that this face grinding wheel can optionally also be used as a non-rotating support surface.
Weiterhin kann eine Schleifspindel, insbesondere die untere Schleifspindel, mit Planeten sowie einem die Planeten innenseitig umgebenden inneren und einem die Planeten außenseitig umgebenden äußeren Stiftkranz versehen sein, wobei ein Stiftkranz, insbesondere der innere Stiftkranz, zum Antrieb der Planeten rotatorisch angetrieben ist, und der andere Stiftkranz zum Abrollen der Planeten ausgebildet ist.Furthermore, a grinding spindle, in particular the lower grinding spindle, can be provided with planets as well as an inner pinion surrounding the planters on the inside and an outer pin crown surrounding the planets on the outside, wherein a pin collar, in particular the inner pin ring, is rotationally driven to drive the planets, and the other Pinion is designed to unroll the planet.
Dabei kann die Schleifspindel mit den Stiftkränzen als Doppelspindel für den Antrieb des die Planeten antreibenden Stiftkranzes einerseits und für den Antrieb der eigentlichen Schleifspindel andererseits ausgebildet sein, wobei insbesondere die Stiftkränze mit den dazwischen geführten Planeten um die vorzugsweise ringförmig ausgebildete Planschleifscheibe angeordnet sind. Hierdurch ergibt sich eine zykloidische Wirkbewegung der Werkstücke auf der/den Planschleifscheibe(n). Alternativ ist auch eine Bewegung des äußeren oder beider Stiftkränze denkbar. Durch die Planetenkinematik wird eine hohe Formgenauigkeit der Werkstücke erzielt.In this case, the grinding spindle can be formed with the pin rings as a double spindle for driving the pinion driving the planets on the one hand and for driving the actual grinding spindle on the other hand, in particular the pin rings are arranged with the planet between them around the preferably annular flat grinding wheel. This results in a cycloidal movement of the workpieces on the face grinding wheel (s). Alternatively, a movement of the outer or both pin rings conceivable. By the planetary kinematics a high dimensional accuracy of the workpieces is achieved.
Auch kann eine Schleifspindel, insbesondere die obere Schleifspindel, als Hohlspindel für die Zufuhr von einem Kühlmedium, insbesondere Kühlwasser, durch die an dieser Schleifspindel vorgesehene Planschleifscheibe ausgebildet sein, so dass zusätzliche Elemente für die Zufuhr des Kühlmediums nicht erforderlich sind und das Kühlmedium in geeigneter Weise an den entsprechenden Bereich der Bearbeitungszone geleitet werden kann.Also, a grinding spindle, in particular the upper grinding spindle, as a hollow spindle for the supply of a cooling medium, in particular cooling water, be formed by the grinding wheel provided on this grinding wheel, so that additional elements for the supply of the cooling medium are not required and the cooling medium in a suitable manner can be passed to the corresponding area of the processing zone.
Vorteilhafterweise kann zumindest ein taktiler und/oder ein optischer Messtaster vorgesehen sein, unter den zumindest eine Planschleifscheibe, insbesondere zur Bestimmung der Verschleißhöhe und/oder des Verschleißprofils an vorzugsweise verschiedenen radialen Positionen, bringbar ist.Advantageously, at least one tactile and / or one optical measuring probe can be provided, under which at least one flat grinding wheel, in particular for determining the wear height and / or the wear profile, can be brought to preferably different radial positions.
Auch kann eine Spindel mit einem Messkopf, insbesondere einem in Richtung der anderen Spindel bzw. des Gegenlagers verlängert angebrachtem Messkopf und die andere Spindel bzw. das Gegenlager mit einer Maßverkörperung, insbesondere einer zur Ermöglichung von Messungen bei unterschiedlichen Drehlagen gekrümmt ausgebildeten Maßverkörperung, versehen sein, so dass durch direkte Messung zwischen der Schleifspindel und dem Gegenlager keine Summenfehler gegenüber Einzelmessungen der jeweiligen Positionen resultiert und die Messung zudem nahe an der Bearbeitungszone erfolgt. Durch die gekrümmt ausgebildeten Maßverkörperung sind Messung bei unterschiedlichen Drehlagen möglich.Also, a spindle having a measuring head, in particular a measuring head extended in the direction of the other spindle or of the abutment, and the other spindle or abutment with a material measure, in particular a measuring graduation curved to allow measurements at different rotational positions, be provided so that no cumulative errors compared to individual measurements of the respective positions results by direct measurement between the grinding spindle and the anvil and the measurement also takes place close to the processing zone. Due to the curved measuring scale measurement at different rotational positions are possible.
Erfindungsgemäß kann ein Tisch zum Be- und Entladen mit einer Planetenkinematik mit Planeten sowie einem die Planeten innenseitig umgebenden inneren und einem die Planeten außenseitig umgebenden äußeren Stiftkranz versehen sein, wobei ein Stiftkranz, insbesondere der innere Stiftkranz, zum Antrieb der Planeten rotatorisch angetrieben ist, und der andere Stiftkranz zum Abrollen der Planeten ausgebildet ist, wobei der Tisch außerhalb des Schleifbereichs angeordnet ist.According to the invention, a table for loading and unloading can be provided with planetary kinematics with planets as well as an outer pinion surrounding the planets on the inside and an outer pin crown surrounding the planets on the outside, wherein a pin collar, in particular the inner pin ring, is rotationally driven to drive the planets, and the other pin collar is designed to roll the planets, the table being located outside the grinding area.
Dabei können die Stifte zumindest eines Teilbereichs des jeweiligen äußeren Stiftkranzes sowohl von der Maschine als auch vom Tisch zum Entladen von Planeten oder zum Beladen mit Planeten zumindest in einem Teilbereich absenkbar ausgebildet sein, so dass ein automatisiertes Be- und Entladen erfolgen kann, in dem die beiden äußeren Stiftkränze abgesenkt und die Planeten beispielsweise mittels eines Schiebers zwischen dem Tisch und der Planschleifscheibe übergeben werden. Damit ist die Bestückung des Tischs parallel zu einer laufenden Schleifbearbeitung möglich.In this case, the pins of at least a portion of the respective outer pin collar can be formed lowerable at least in a partial region both of the machine and the table for unloading planets or for loading with planets, so that an automated loading and unloading can be done in which the lowered both outer pin rings and the planet, for example, be passed by means of a slider between the table and the flat grinding wheel. This makes it possible to equip the table parallel to an ongoing grinding process.
Bei einem bevorzugten Ausführungsbeispiel der Erfindung kann ein Abrichtsystem für ein automatisiertes Abrichten vorgesehen sein, wobei die Planschleifscheibe für die Zustellbewegung beim Abrichten verlagerbar ist, so dass ein automatisiertes Abrichten durch ein Abrichtsystem, an welches wenigsten eine Planschleifscheibe herangeschwenkt wird, erfolgen kann.In a preferred embodiment of the invention, a dressing system for automated dressing can be provided, wherein the flat grinding wheel for the delivery movement during dressing is displaceable, so that an automated dressing by a dressing system, to which At least one surface grinding wheel is pivoted, can take place.
