Abstract

The face grinding wheel consists of a stiff backing plate (10) and a replaceable grinding disc (14). The backing plate has a central shaft (11) and mounting screw (18). On the face of the backing plate are small mushroom headed plastics rods (12) which key onto the joining surface (15) of the grinding disc (14). The surface has a nap derived from a chain of looped thread which is laid on a laminated fabric carrier disc (13). Cemented to the carrier disc is a grinding ring of laminated construction. The grinding disc overlaps the backing plate to enable the outer edge to be used for grinding into corners. - The grinding disc may be secured by a central nut (20) but this is not essential because the shear force is easily sustained by the joint interface.

Description

Die Erfindung betrifft ein Fächerstirnschleifwerkzeug mit einem Stützteller, der mit einem Befestigungsmittel zum Aufsetzen auf eine Antriebsmaschine versehen ist, sowie mit einer Schleifscheibe, die einen kreisscheibenförmigen, lösbar am Stützteller befestigbaren Träger und darauf befestigte, radial ausgerichtete, sich fächerartig überlappenden Schleiflamellen aufweist. Die Erfindung betrifft fesner einen Schleiflamellenträger für ein derartiges Fächerstirnschleifwerkzeug.The invention relates to a flap face grinding tool with a support plate, which is provided with a fastening means for mounting on a drive machine, and with a grinding wheel, which has a circular disk-shaped carrier, releasably attachable to the support plate, and radially aligned, fan-overlapping grinding flaps fastened thereon. The invention also relates to a grinding disk carrier for such a flap tool.

Ein derartiges Werkzeug ist aus der US-A- 3,616,581 bekannt. Der Stützteller weist einen erhabenen Ring auf, der mit einem Gummibelag versehen ist. Der Träger ist mit radialen Schlitzen versehen, in welche jeweils eine Schleiflamelle in der Weise eingesteckt ist, daß auf der der Schleifseite abgewandten Rückseite ein Rand übersteht. Der Träger wird mit einer zentrischen Schraube auf den Stützteller aufgeschraubt, wobei die überstehenden Ränder zwischen dem Träger und dem Ringbereich zur Verankerung der Schleiflamellen fest eingeklemmt werden. Die Bestückung mit Schleiflamellen erfolgt jeweils vor Ort, indem der Träger abgeschraubt, die Schleiflamellen eingesteckt und anschließend der Träger wieder auf den Stützteller aufgeschraubt werden. Die Umrüstzeiten sind daher relativ lang und erfordern große Sorgfalt.Such a tool is known from US-A-3,616,581. The support plate has a raised ring, which is provided with a rubber covering. The carrier is provided with radial slots, into each of which a grinding flap is inserted in such a way that an edge protrudes on the rear side facing away from the grinding side. The carrier is screwed onto the support plate with a central screw, the protruding edges between the carrier and the ring area being firmly clamped in order to anchor the grinding flaps. The grinding lamellas are fitted on site by unscrewing the carrier, inserting the grinding lamella and then screwing the carrier back onto the support plate. The changeover times are therefore relatively long and require great care.

Es sind auch Fächerstirnschleifscheiben bekannt, die einen mit radialen Schlitzen und einen mit einem Dorn versehenen Kunststoffteller aufweisen, und bei welchen die Schleiflamellen in die radialen Schlitze eingeklebt sind. Wenn das Schleifmittel abgearbeitet ist, bilden die Kunststoffteller einen schwer entsorgbaren Abfall. Schließlich sind auch Fächerstirnschleifscheiben mit einem Teller aus wiederverwertbarem Aluminium bekannt, bei welchen die Schleiflamellen durch mechanische Klemmung in Radialschlitzen verankert oder auf einer geschlossenen Tellerfläche mit Kleber befestigt sind.There are also known front-face grinding wheels which have a plastic plate provided with radial slots and a mandrel, and in which the grinding flaps are glued into the radial slots. When the abrasive is finished, the plastic plates form a waste that is difficult to dispose of. Finally, too Knife flap discs with a plate made of recyclable aluminum are known, in which the grinding flaps are anchored in radial slots by mechanical clamping or fastened to a closed plate surface with adhesive.

Der Erfindung liegt die Aufgabe zugrunde, ein Fächerstirnschleifwerkzeug und einen Schleiflamellenträger der eingangs genannten Art anzugeben, bei welchen die Umrüstzeiten verkürzt werden.The invention is based on the object of specifying a flap face grinding tool and a grinding disk carrier of the type mentioned at the outset, in which the changeover times are shortened.

Diese Aufgabe wird durch die Merkmale der Ansprüche 1 und 12 gelöst. Die Erfindung hat den Vorteil, daß der Teller auf einfache Weise und mit wenig Werkzeugverschleiß ausgestanzt werden kann. Außerdem geht der Kleber eine gute Verbindung mit dem Gewebe ein, so daß die Schleiflamellen sicher verankert werden. Ferner kann der Flächenhaftverschluß aufgrund der Flexibilität des Trägers noch leichter gelöst werden.This object is solved by the features of claims 1 and 12. The invention has the advantage that the plate can be punched out in a simple manner and with little tool wear. The adhesive also forms a good bond with the fabric so that the sanding flaps are securely anchored. Furthermore, the surface fastener can be released even more easily due to the flexibility of the carrier.

Nach einer bevorzugten Weiterbildung besteht das Verbindungsmittel aus einer trägerseitig aufgebrachten Schicht eines lösbaren Klebers. Bis zum Gebrauch kann diese selbsthaftende Schicht beispielsweise mit einer abziehbaren Schutzfolie bedeckt sein.According to a preferred development, the connecting means consists of a layer of a releasable adhesive applied on the carrier side. Until use, this self-adhesive layer can be covered, for example, with a removable protective film.

Es ist besonders vorteilhaft, daß das Verbindungsmittel zwischen Träger und Stützteller ein Flächenhaftverschluß (Klettenverschluß) ist.It is particularly advantageous that the connecting means between the carrier and the support plate is a surface fastener (Velcro fastener).

Unter einem Flächenhaftverschluß, der auch als Klettenbandverschluß oder Klettenreißverschluß bezeichnet wird, versteht man zwei zu einer besonderen Reißverschlußart gehörige Oberflächen mit unterschiedlichem Oberflächeneffekt. Die eine Oberfläche ist webtechnisch z.B. mit losen Kettenfädenschlaufen aus multifilen Synthetiks versehen. Die andere Oberfläche trägt auf ihrer Oberseite beispielsweise eine Vielzahl von kleinen Häkchen oder Kugel- oder Pilzköpfchen, die aus monofilen Klettfäden oder ähnlichen gebildet werden. Hierdurch entsteht beim Aufeinanderlegen beider Bänder eine klettenartige Haftwirkung.A surface fastener, which is also referred to as a Velcro fastener or Velcro fastener, is understood to mean two surfaces belonging to a particular type of zip fastener with different surface effects. In terms of weaving technology, one surface is provided with loose chain thread loops made of multifilament synthetics. The other surface has, for example, a large number of small hooks or spherical or mushroom heads on its upper side, which are formed from monofilament Velcro threads or the like. This creates a Velcro-like adhesive effect when the two tapes are placed on top of each other.

Die Erfindung hat ferner den Vorteil, daß der Träger auf einfache Weise mit einer Bewegung senkrecht zur Tellerfläche vom Stützteller entfernt werden kann. Trotzdem wird der Teller im Schleifbetrieb sicher gehalten, da die Wirkung der ausschließlich auftretenden Scherkräfte kleiner ist als die Oberflächenhaftwirkung.The invention also has the advantage that the carrier can be removed from the support plate in a simple manner with a movement perpendicular to the plate surface. Nevertheless, the plate is held securely in the grinding mode, since the effect of the shear forces that occur is smaller than the surface adhesion.

Es ist grundsätzlich möglich, den Träger aus einem Gewebe aus Kunststoffäden herzustellen. Aus Umweltschutzgründen ist es jedoch besonders vorteilhaft, daß das Gewebe aus einem Naturfasergewebe besteht. Das hat den weiteren Vorteil, daß es mit einem Imprägniermittel behandelt werden kann, welches die Haftwirkung und Verbindung mit dem die Schleiflamellen fixierenden Klebemittel verbessert.In principle, it is possible to manufacture the carrier from a fabric made of plastic threads. For reasons of environmental protection, however, it is particularly advantageous that the fabric consists of a natural fiber fabric. This has the further advantage that it can be treated with an impregnating agent which improves the adhesive effect and connection with the adhesive which fixes the abrasive flaps.

Es kann ferner vorteilhaft sein, daß der Träger aus mehreren Lagen besteht, so daß die Verankerungswirkung, die Flexibilität und die Gewebeöffnungen insbesondere im Hinblick auch auf die Korngröße der Schleiflamellen optimiert werden.It can also be advantageous for the carrier to consist of several layers, so that the anchoring effect, the flexibility and the fabric openings are optimized in particular with regard to the grain size of the grinding flaps.

Die Anwendungsmöglichkeiten des Lamellenschleifwerkzeugs werden dadurch besonders groß, daß der Außendurchmesser des Trägers und des Schleiflamellenkranzes größer ist als der Außendurchmesser des Stütztellers. Auf diese Weise wird ein Überstand erzeugt, der es ermöglicht, auch in Ecken und Schlitzen zu schleifen. Diese Weiterbildung ist besonders wirtschaftlich, da nach dem Abarbeiten des Außenbereichs der Schleiflamellen und entsprechender Außendurchmesser-Verringerung jeweils ein kleinerer Stützteller eingesetzt werden kann, so daß die Schleifscheibe nahezu vollständig von aussen nach innen abgearbeitet werden kann. Außerdem kann durch entsprechende Wahl des Schleifscheiben-Überstandes gezielt ein härteres oder weicheres Schleifen erfolgen. Das bedeutet mit anderen Worten, daß mit einem Satz von Stütztellern unterschiedlichen Durchmessers sowohl verschiedene Schleifaufgaben gelöst werden können als auch das Schleifgewebe optimal ausgenutzt werden kann.The possible applications of the flap grinding tool are particularly large in that the outer diameter of the carrier and the grinding flap ring is larger than that Outside diameter of the support plate. In this way, a protrusion is created that also allows grinding in corners and slots. This development is particularly economical, since after the outer area of the grinding flaps has been worked off and a corresponding reduction in the outer diameter, a smaller support plate can be used, so that the grinding wheel can be worked almost completely from the outside to the inside. In addition, by selecting the grinding wheel protrusion appropriately, a harder or softer grinding can be carried out. In other words, this means that with a set of support plates of different diameters, different grinding tasks can be solved and the grinding fabric can be optimally used.

Eine besonders einfache Zentrierung der Schleifscheibe bzw. des Trägers auf dem Stützteller wird dadurch erreicht, daß der Stützteller und die Schleifscheibe mit jeweils einer übereinstimmenden Lochung versehen sind. Bringt man beide Lochungen, beispielsweise mit Hilfe eines separaten Stifts, fluchtend übereinander, so sind Stützteller und Schleifscheibe konzentrisch.A particularly simple centering of the grinding wheel or the carrier on the support plate is achieved in that the support plate and the grinding wheel are each provided with a matching perforation. If you align both perforations one above the other, for example with the help of a separate pin, the backing plate and grinding wheel are concentric.

Alternativ oder zusätzlich kann es auch vorteilhaft sein, auf der dem Stützteller zugewandten Seite des Trägers konzentrische Markierungen anzubringen, deren Durchmesser den unterschiedlichen Stützteller-Durchmessern entspricht. Somit kann der richtige Sitz ständig überprüft werden.Alternatively or additionally, it can also be advantageous to make concentric markings on the side of the carrier facing the support plate, the diameter of which corresponds to the different support plate diameters. This means that the correct fit can be checked continuously.

Als zusätzliche Sicherungsmaßnahme und zum einfachen Zentrieren ist es gemäß einer weiteren Ausgestaltung der Erfindung zweckmäßig, daß der Stützteller mit einem zentrischen, schleifscheibenseitigen Schraubbolzen bzw. mit einer Gewindebohrung und einer entsprechenden Ausnehmung zur Aufnahme des betreffenden Gegenstücks versehen ist. Da der Flächenhaftverschluß die Schleifscheibe hält und die Schraubverbindung im wesentlichen lediglich als Sicherung vor einem unbeabsichtigten Ablösen im Ruhezustand dient, kann sie entsprechend leicht ausgebildet sein.As an additional safety measure and for easy centering, it is expedient according to a further embodiment of the invention that the support plate is provided with a central, grinding wheel-side screw bolt or with a threaded bore and a corresponding recess for receiving the relevant counterpart. Since the Surface fastener holds the grinding wheel and the screw connection essentially serves only as a safeguard against unintentional detachment in the idle state, it can be made correspondingly light.

Eine besonders kostengünstige Herstellung der Schleifscheibe wird dadurch erreicht, daß die zum Flächenhaftverschluß gehörige Oberfläche aus den losen Kettenfadenschlaufen oder aus einer Florware besteht und daß der stütztellerseitige Teil des Flächenhaftverschlusses aus den Tentakel-Haftmitteln besteht. Außerdem hat diese Weiterbildung den Vorteil, daß der Kunststoffanteil der Schleifscheibe weiter gesenkt wird.A particularly inexpensive manufacture of the grinding wheel is achieved in that the surface belonging to the surface fastener consists of the loose chain thread loops or a pile fabric and that the support plate-side part of the surface fastener consists of the tentacle adhesives. In addition, this development has the advantage that the plastic portion of the grinding wheel is further reduced.

Nachfolgend wird die Erfindung anhand eines in der Zeichnung dargestellten Ausführungsbeispiels weiter beschrieben.

  • Fig. 1 zeigt schematisch einen Radialquerschnitt durch ein Lamellenschleifwerkzeug in einer Explosionsdarstellung und
  • Fig. 2 zeigt eine Teildraufsicht auf das Lamellenschleifwerkzeug gemäß Pfeil II in Fig. 1.
The invention is described below with reference to an embodiment shown in the drawing.
  • Fig. 1 shows schematically a radial cross section through a flap grinding tool in an exploded view and
  • FIG. 2 shows a partial top view of the flap grinding tool according to arrow II in FIG. 1.

Gemäß Fig. 1 ist ein im wesentlichen biegesteifer Stützteller 10 mit einem zentrischen Dorn 11 versehen, mit welchem dieser in einem Schraubfutter einer Antriebsmaschine (nicht dargestellt) eingesetzt werden kann. Auf der dem Dorn 11 abgewandten Seite ist der Stützteller 10 großflächig mit pilzartigen, elastischen Kunststoff-Tentakeln 12 versehen, welche eine Oberfläche eines Flächenhaftverschlusses (Klettenverschluß 9) bilden.1, a substantially rigid support plate 10 is provided with a central mandrel 11, with which this can be used in a screw chuck of a drive machine (not shown). On the side facing away from the mandrel 11, the support plate 10 is provided over a large area with mushroom-like, elastic plastic tentacles 12 which form a surface of a surface fastener (Velcro fastener 9).

Die Gegenfläche des Flächenhaftverschlusses 9 befindet sich auf einem kreisscheibenförmigen Träger 13 einer separaten Schleifscheibe 14. Diese Oberfläche wird von einer Florware 15 aus losen Kettfadenschlaufen gebildet.The counter surface of the surface fastener 9 is located on a circular disk-shaped carrier 13 of a separate grinding wheel 14. This surface is formed by a pile 15 of loose warp thread loops.

Auf der anderen Seite des Trägers 13 sind sich fächerartig überlappende Schleiflamellen 16 radial angeordnet, so daß ein Schleiflamellenring gebildet wird. Die Schleiflamellen 16 bestehen jeweils aus einem Gewebe mit einer mit Schleifkorn beschichteten Oberfläche. Sie sind an ihren Stirnseiten auf den Träger 13 aufgeklebt.On the other side of the carrier 13 there are radially overlapping grinding lamellae 16, so that a grinding lamella ring is formed. The grinding flaps 16 each consist of a fabric with a surface coated with abrasive grain. They are glued to the carrier 13 at their end faces.

Beim Träger 13 handelt es sich im vorliegenden Fall um ein Gewebe aus Naturfasern, welches zur guten Verbindung mit dem Kleber mit einem Imprägniermittel behandelt ist. Die Schleifscheibe 14 ist insgesamt in sich flexibel, wenngleich grundsätzlich auch ein steifer Träger 13 möglich ist.In the present case, the carrier 13 is a woven fabric made of natural fibers, which is treated with an impregnating agent for a good connection with the adhesive. The grinding wheel 14 is flexible in itself, although in principle a rigid support 13 is also possible.

Der Außendurchmesser des Trägers 13 weist gegenüber dem Außendurchmesser des Stütztellers 10 einen vorgegebenen Überstand a auf, so daß das Lamellenschleifwerkzeug nicht nur für einen großflächigen Schleifbetrieb eingesetzt werden kann, sondern auch aufgrund des Überstandes a Ecken und ähnliches bearbeitet werden können.The outer diameter of the carrier 13 has a predetermined protrusion a compared to the outer diameter of the support plate 10, so that the flap grinding tool can not only be used for large-area grinding operation, but also corners and the like can be machined due to the protrusion.

Im Stützteller 10 ist mittig eine Ausnehmung 17 mit einem zentrischen Gewindebolzen 18 vorhanden, der bündig mit der Oberfläche des Stütztellers 10 abschließt. Der Gewindebolzen 18 wirkt mit einer zentrischen Lochung 19 im Träger 13 zusammen, so daß eine konzentrische Anordnung von Stützteller 10 und Schleifscheibe 14 sichergestellt ist.In the support plate 10 there is a recess 17 in the center with a central threaded bolt 18 which is flush with the surface of the support plate 10. The threaded bolt 18 cooperates with a central perforation 19 in the carrier 13, so that a concentric arrangement of the support plate 10 and grinding wheel 14 is ensured.

Der Träger 13 bzw. die Schleifscheibe 14 werden dadurch am Stützteller 10 befestigt, daß zunächst die Lochung 19 auf den Gewindebolzen 18 gesteckt und anschließend die Oberflächen des Flächenhaftverschlusses 9 aufeinandergedrückt werden. Die Tentakel 12 haften dann so fest in der Florware 15, daß ein sicherer Schleifbetrieb möglich ist. Als zusätzliche Sicherung kann eine Sicherungsmutter 20 auf den Gewindebolzen 18 aufgeschraubt werden, wobei die benachbarten Bereiche 21 (Fig. 2) des Trägers 13 in der Ausnehmung 17 verklemmt werden. In der Regel dürfte jedoch eine derartige Sicherung nicht erforderlich sein.The carrier 13 or the grinding wheel 14 are fastened to the support plate 10 by first opening the holes 19 the threaded bolt 18 inserted and then the surfaces of the surface fastener 9 are pressed together. The tentacles 12 then adhere so firmly in the pile 15 that a safe grinding operation is possible. As an additional safeguard, a locking nut 20 can be screwed onto the threaded bolt 18, the adjacent regions 21 (FIG. 2) of the carrier 13 being clamped in the recess 17. As a rule, such a backup should not be necessary.

Zum Entfernen der Schleifscheibe 14 wird der Flächenhaftverschluß 9 auf einfache Weise dadurch gelöst, daß der Träger 13 in Achsrichtung abgezogen wird.To remove the grinding wheel 14, the surface fastener 9 is released in a simple manner in that the carrier 13 is pulled off in the axial direction.

Durch Wahl eines hinsichtlich des Außendurchmessers geeigneten Stütztellers 10 wird erreicht, daß der vorgegebene Überstand a auch nach dem Abarbeiten des Außenbereichs der Schleiflamellen 16 beibehalten wird. Die Schleifscheibe 14 bzw. die Schleiflamellen 16 können daher nahezu vollständig von außen nach innen abgearbeitet werden.By choosing a support plate 10 which is suitable with regard to the outer diameter, it is achieved that the predetermined projection a is maintained even after the outer region of the grinding flaps 16 has been worked off. The grinding wheel 14 or the grinding flaps 16 can therefore be processed almost completely from the outside inwards.

Wie die Draufsicht gemäß Fig. 2 zeigt, ist der Träger 13 im Bereich der Lochung 19 mit radialen Schlitzen 22 versehen, so daß sich der Bereich 21 der Ausnehmung 17 des Stütztellers 10 beim Sichern mit der Sicherungsmutter 20 anpassen kann.As the top view according to FIG. 2 shows, the carrier 13 is provided with radial slots 22 in the area of the perforation 19, so that the area 21 of the recess 17 of the support plate 10 can adapt when securing with the lock nut 20.
