Description

Die Erfindung betrifft eine Schleifmaschine mit einem stationären Wandungsteil und mit einem um eine Drehachse drehbaren Tellerteil, zwischen denen ein Spalt gebildet ist.The invention relates to a grinding machine with a stationary Wall part and with a rotatable about an axis of rotation Plate part, between which a gap is formed.

Eine gattungsgemäße Schleifmaschine ist aus der DE 196 06 117 A1 bekannt. Eine derartige gattungsgemäße Schleifmaschine arbeitet unter Fliehkrafteinwirkung, indem in den durch Wandung und Tellerteil gebildeten Innenraum sowohl zu bearbeitende Werkstücke als auch Schleifmaterial eingefüllt und beide durch Drehung des Tellerteils in Drehung gesetzt werden, so dass eine Polierwirkung durch Fliehkraft-Einwirkung und Relativgeschwindigkeiten von Werkstücken und Schleifmaterialkörner bewirkt wird.A generic grinding machine is from DE 196 06 117 A1 known. Such a generic grinding machine works under centrifugal force by in the interior formed by wall and plate part both to machining workpieces and grinding material and both set in rotation by rotating the plate part be so that a polishing action by centrifugal action and relative speeds of workpieces and Abrasive material grains is caused.

Bei einem bekannten Gegenstand wird der Ringspalt zwischen drehbarem Tellerteil und stationärem Wandungsteil von der Oberseite her durch eine elastische Auskleidung des Wandungsteils und auf der Unterseite durch einen am Drehteller angebrachten Keramikring begrenzt, wobei die Ausbildung des Tellerteils unmittelbar unterhalb des einen rechteckigen Querschnitt aufweisenden Keramikringes sich nach unten und innen verjüngend ausgebildet ist. Während die elastische Auskleidung aufgrund ihrer Elastizität kaum einem Verschleiß durch das die Schleifmaterialkörper unterliegt, hat sich herausgestellt, dass der Keramikring bei lauten Schleifkörpern einem hohen Verschleiß ausgesetzt ist, der insbesondere dadurch bewirkt wird, dass sich Schleifmaterialkörper im Spalt festsetzen und aufgrund ihrer abrasiven Wirkung den Keramikring im Bereich seiner inneren oberen Kante abschleifen, so dass nach kurzer Zeit eine Stufe mit einer Tiefe von 3 mm bis 5 mm gebildet wird. In dieser kann sich wiederum Schleifmaterial festsetzen, das sich bis zur Unterkante der Auskleidung der stationären Wandung aufstaut und aufgrund der zwischen Wandung und Tellerteil gebildeten Relativbewegung zum weiteren Abtrag des Keramikteils beiträgt. Dieses muss daher nach kurzer Zeit ersetzt werden.In a known object, the annular gap between rotatable plate part and stationary wall part from the Top side by an elastic lining of the wall part and on the bottom by one on the turntable attached ceramic ring limited, the formation of the Plate part immediately below the one rectangular Cross section ceramic ring down and is tapered inside. While the elastic Lining hardly wear due to its elasticity through which the abrasive material body is subject it turned out that the ceramic ring is loud Grinding bodies are subject to high wear, which is caused in particular by the fact that abrasive material body get stuck in the gap and due to their abrasive Effect the ceramic ring in the area of its inner top Grind off the edge so that after a short time a step with a depth of 3 mm to 5 mm is formed. In this can in turn, abrasive material will settle down to the Bottom edge of the lining of the stationary wall and because of the formed between the wall and the plate part Relative movement contributes to the further removal of the ceramic part. This must therefore be replaced after a short time.

Der Erfindung liegt daher die Aufgabe zugrunde eine Schleifmaschine der eingangs genannten Art dahingehend weiterzuentwickeln, das eine höhere Standzeit aufweist.The invention is therefore based on the object To further develop the grinding machine of the type mentioned at the beginning, which has a longer service life.

Erfindungsgemäß wird die genannte Aufgabe mit einer Schleifmaschine der eingangs genannten Art gelöst, welche dadurch gekennzeichnet ist, dass der Spalt von oben durch ein Keramikteil und von unten durch ein elastisches Teil begrenzt ist. Es hat sich überraschenderweise herausgestellt, dass die abrasive Wirkung der Schleifmaterialkörper bei einer Anordnung des Keramikteils an der unteren Seite der stationären Wandung und damit der Begrenzung des Spaltes durch den Keramikring von oben bei der unteren Begrenzung des Spaltes durch die elastische Auskleidung des drehbaren Tellerteils das Keramikteil einem viel geringeren Verschleiß ausgesetzt ist, als dies beim Stande der Technik der Fall ist. Dies mag daran liegen, dass sich zwar aufgrund der abrasiven Wirkung der Schleifmaterialkörper auch eine kleine Stufe im Bereich der inneren unteren Kante des Keramikrings ausbildet, sich Schleifmaterial aber hier nicht festsetzen und auftürmen kann, da es durch die unbeschädigte gegenüberliegende Kante der elastischen Auskleidung des Tellerteils immer wieder fortgetragen wird.According to the invention, the stated object is achieved with a Solved grinding machine of the type mentioned, which is characterized in that the gap from above a ceramic part and from below by an elastic part is limited. Surprisingly, it turned out that the abrasive effect of the abrasive material body with an arrangement of the ceramic part on the lower side the stationary wall and thus the limitation of the gap through the ceramic ring from above at the lower limit of the gap through the elastic lining of the rotatable plate part the ceramic part a much smaller Wear is more exposed than in the prior art the case is. This may be due to the fact that due to the abrasive effect of the abrasive material bodies too a small step in the area of the inner lower edge of the Ceramic ring forms, but grinding material here cannot fix and pile up as it is undamaged by the opposite edge of the elastic lining of the plate part is carried away again and again.

Durch die Erfindung wird damit eine wesentlich höhere Standzeit erreicht als dies beim Stand der Technik der Fall ist. Ein Austauschen des Keramikringes ist erst nach wesentlich längerer Standzeit erforderlich.The invention thus makes a much higher one Tool life reaches than is the case with the prior art is. Replacing the ceramic ring is only essential after longer service life required.

Das elastische Teil des Tellerteils ist vorzugsweise eine Auskleidung desselben, während das Keramikteil als Keramikring ausgebildet ist. Vorzugsweise sind zwischen beiden einander gegenüberliegenden Ebenen Oberflächen vorgesehen, die insbesondere horizontal und senkrecht zur Drehachse gerichtet sind; sie können aber auch eine leichte nach innen verlaufenden Neigung der Horizontalen beispielsweise im Bereich von 10° bis 30° einschließen. In der Regel wird die Achse der Schleifmaschine senkrecht gerichtet sein. Eine äußerst bevorzugte Ausgestaltung der Erfindung zeichnet sich dadurch aus, dass das Keramikteil einen nach unten gerichteten nasenartigen Vorsprung aufweist, wobei insbesondere die Innenwandung von Tellerteil und Wandungsteil oberhalb und unterhalb des Spaltes von oben nach unten verengend im wesentlichen kegelförmig ausgebildet sind. Die Kegelneigung der Innenwandung zur senkrechten Drehachse kann dabei 30° bis 45° betragen. Insbesondere diese geneigte Ausbildung nicht nur des Tellerteils unmittelbar unterhalb des Spaltes, sondern die Aufnahme der nach innen unten verlaufenden Kegelneigung schon durch die Innenwandung des Wandungsteils unterstützt die Abtrag hindernde Anordnung von spaltbegrenzendem Keramikteil am oberen Wandteil und ebenfalls den Spalt an seiner Unterseite begrenzenden elastischen Teil des Drehtellers.The elastic part of the plate part is preferably one Lining the same, while the ceramic part as a ceramic ring is trained. Are preferably between the two opposing planes provided surfaces which are directed particularly horizontally and perpendicular to the axis of rotation are; but they can also be a slight inside gradient of the horizontal, for example in the area enclose from 10 ° to 30 °. As a rule, the Axis of the grinding machine must be directed vertically. A extremely preferred embodiment of the invention is characterized in that the ceramic part is directed downwards has nose-like projection, in particular the inner wall of the plate part and the wall part above and narrowing from top to bottom below the gap are essentially conical. The taper the inner wall to the vertical axis of rotation 30 ° to 45 °. In particular, this inclined Training not only of the plate part immediately below of the gap, but the inclusion of the inward downward Tapering already through the inner wall of the Part of the wall supports the abrasion-preventing arrangement of gap-limiting ceramic part on the upper wall part and also elastic gap limiting the gap on its underside Part of the turntable.

FIG. 2 shows an enlarged detailed illustration of the object of FIG. 1.

Die Fig. 1 zeigt in vertikalem Längsschnitt eine bevorzugte Ausführungsform einer erfindungsgemäßen Schleifmaschine 1. Diese ist um ihre Drehachse A symmetrisch aufgebaut, so dass im wesentlichen lediglich der rechte Teil des Vertikalschnittes dargestellt ist. Die erfindungsgemäße Schleifmaschine 1 weist ein stationäres Wandungsteil 2 auf. Unterhalb desselben ist ein um die Achse A mittels einer Antriebswelle 3 drehbares Tellerteil 4 vorgesehen. Außerhalb des Tellerteils 4 kann sich, muss sich aber nicht, dieses umschließend an der Unterseite des Wandungsteils 2 mit Abstand zum Tellerteil 4 ein stationäres Unterteil 6 anschließen. Die genannten Teile bestehen im wesentlichen aus Metall, wie Aluminium. Das Wandungsteil 3 und das Bodenteil 4 weisen innenseitig eine elastische Auskleidung 7, 8, vorzugsweise aus Polyurethan, auf. An der Unterseite des Wandungsteils 2 ist ein Keramikring 9 vorgesehen, der fest mit dem Wandungsteil 2 verbunden ist. Fig. 1 shows a preferred longitudinal section Embodiment of a grinding machine 1 according to the invention. This is constructed symmetrically about its axis of rotation A, see above that essentially only the right part of the vertical section is shown. The grinding machine according to the invention 1 has a stationary wall part 2. Below the same is one around the axis A by means of a drive shaft 3 rotatable plate part 4 is provided. Outside the plate part 4 can, but need not, this enclosing at the bottom of the wall part 2 at a distance Connect a stationary lower part 6 to the plate part 4. The parts mentioned essentially consist of Metal, like aluminum. The wall part 3 and the bottom part 4 have an elastic lining 7, 8 on the inside, preferably made of polyurethane, on. At the bottom of the wall part 2, a ceramic ring 9 is provided, which is fixed with the wall part 2 is connected.

Die Innenwandung der elastischen Auskleidung 7 und damit des Wandungsteils 2 weist im unteren Bereich eine sich verjüngende Neigung zur durch die Drehachse A bestimmten Vertikalen auf, wobei der Neigungswinkel beispielsweise in einem Bereich von 30° bis 45° liegen kann. Dieser Neigung folgt im wesentlichen die Innenwandung 11 des Keramikrings 9, dessen obere Wandungsseite 12 und rückwärtige Wandung 13 im wesentlichen senkrecht zueinander und senkrecht bzw. parallel zur Achse A gerichtet sind. Der Keramikring weist an seiner unteren inneren Seite einen nasenartigen Vorsprung 14 nach unten auf, der in seinem rückwärtigen Bereich über eine von eine Kante 16a aus von unten schräg nach oben und außen verlaufenden Schräge 16 in einen horizontalen bzw. sich senkrecht zur Drehachse A erstreckenden äußeren unteren Wandungsbereich 17 bis zur Außenkante 17a des Keramikrings 9 übergeht. Die Schräge 16 kann auch von der Kante 16a bis zur Kante 17a durchgehend verlaufen, so dass der horizontale Bereich 17 entfällt.The inner wall of the elastic lining 7 and thus of the wall part 2 has a tapering in the lower region Inclination to the vertical determined by the axis of rotation A. on, the angle of inclination for example in a May range from 30 ° to 45 °. This inclination essentially follows the inner wall 11 of the ceramic ring 9, the upper wall side 12 and rear wall 13 essentially perpendicular to each other and perpendicular or parallel are directed to the axis A. The ceramic ring instructs a nose-like projection on its lower inner side 14 down on that in its rear area over one from an edge 16a from below obliquely upwards and outside slope 16 into a horizontal or extending perpendicular to the axis of rotation A outer lower Wall area 17 to the outer edge 17a of the ceramic ring 9 passes. The slope 16 can also from the edge 16a to the edge 17a run continuously, so that the horizontal area 17 is omitted.

Die Oberseite 19 der elastischen Auskleidung 8 des Tellerteils 4 ist im wesentlichen über die Oberseite 19 des letzteren nach außen mit einem Fortsatz 18 abgewinkelt. Die obere Fläche des Fortsatzes 18 ist eben und erstreckt sich parallel zur Unterseite der Nase 14a.The top 19 of the elastic lining 8 of the plate part 4 is essentially over the top 19 of the latter angled outward with an extension 18. The upper surface of the extension 18 is flat and extends parallel to the underside of the nose 14a.

Der Einsatz der Schleifmaschine 1 erfolgt durch Eingabe von Werkstücken, wie Ringen oder dgl., und Schleifmaterial in den durch die Wandung 2 und den Teller 4 gebildeten Innenraum sowie Drehung des Tellerteils 4 mit hoher Geschwindigkeit. Hierdurch werden Werkstücke mittels des Schleifmaterials geschliffen. Beim Betrieb gelangt Schleifmaterial in den Bereich des Spaltes S. Aufgrund der Elastizität der elastischen Auskleidung 8 sind die abrasiven Einwirkungen auf diese relativ gering; sie sind höher auf den Keramikring, insbesondere im Bereich seiner inneren unteren Kante 21.The grinding machine 1 is used by entering Workpieces such as rings or the like, and grinding material in the interior formed by the wall 2 and the plate 4 and rotation of the plate part 4 at high speed. As a result, workpieces are made using the abrasive material ground. Abrasive material gets into during operation the area of the gap S. Due to the elasticity of the elastic lining 8 are the abrasive effects relatively low on this; they are higher on the ceramic ring, especially in the area of its inner lower edge 21st

Es hat sich herausgestellt, dass der abrasive Einfluss und damit der Abtrag des Keramikringes bei der erfindungsgemäßen Ausgestaltung wesentlich geringer ist, als dies beim Stand der Technik der Fall ist. It has been found that the abrasive influence and thus the removal of the ceramic ring in the invention Design is much less than this State of the art is the case.
