In an abrasive tool for grinding or polishing, a grippable shaft is connected to an abrasive disc by means of a cylindrical elastic pad of plastic or rubber. A surrounding cap, preferably a screw cap, is provided, which for stiffening the assembly is adapted to be secured at one end to the abrasive disc and is engageable at its other end by means of an annular shoulder to an annular shoulder of the grippable shaft. Alternatively, the grippable shaft may extend through a cylindrical elastic ring of plastic or rubber, which ring is surrounded to a metal sleeve, which is connected to the abrasive disc and adapted to be tightened by a nut so as to stiffen the tool.

Description

Die Erfindung bezieht sich auf einen Schleif- oder Polierteller mit einem Einspannschaft und Endflansch entsprechend dem Oberbegriff.The invention relates to a grinding or polishing plate with a clamping shaft and end flange according to the preamble.

Nach der US-PS 26 29 990 ist ein Schleifteller bekannt mit einem Einspannschaft und Endflansch, welchem ein anvulkanisierter Elastomerpuffer mit Befestigungsflansch für den Schleif- oder Polierteller folgt, wodurch eine elastische Anlage beim Schleifen erreicht werden soll.According to US-PS 26 29 990 a grinding plate is known with a clamping shaft and end flange, which is followed by a vulcanized elastomer buffer with a mounting flange for the grinding or polishing plate, whereby an elastic system should be achieved during grinding.

Desweiteren ist nach der DE-OS 33 01 210 ein Trägerkopf für Arbeitsscheiben bekannt mit einem Einspannschaft und Endflansch, sowie einem Gewinde am Einspannschaft, welchem Schaft ein anvulkanisierter Elastomerpuffer mit Hülse zugeordnet ist. Hierbei geht es um die bewegliche Ausbildung des Trägerkopfes und dessen stoßfreies Nachgeben.Furthermore, according to DE-OS 33 01 210, a carrier head for working disks is known with a clamping shaft and end flange, and a thread on the clamping shaft, which shaft is associated with a vulcanized elastomer buffer with a sleeve. This is about the flexible design of the carrier head and its bumpless yielding.

Schließlich ist die DE-OS 32 22 858 bekannt, welche eine Schleif- oder Polierscheibe betrifft, bestehend aus einem Plattenteller mit aufbringbarem Schleif- oder Polierbelag, wobei die Scheibe mittels Endstutzen eines biegsamen Wellenstücks in einem Antriebsfutter einspannbar und mittels starrem Über- oder Einschub versteifbar ist.Finally, DE-OS 32 22 858 is known, which relates to a grinding or polishing disc, consisting of a platter with an attachable grinding or polishing pad, the disc being clampable in a drive chuck by means of end pieces of a flexible shaft piece and stiffening by means of rigid over or insertion is.

Hiernach ist es bekannt eine biegsame Welle für den Antrieb des Schleiftellers zu verwenden, welche überdies durch einen starren Über oder Einschub versteifbar ist, so dass bei steifer Welle die Verwendung zum Flachschleifen und -Polieren mit ein und derselben Vorrichtung ermöglicht wird. Es hat sich dabei gezeigt, dass bei hoher Belastung abhängig auch von der Schleiftellergrösse und hohen Drehzahlen, wie dies im Gegensatz zu Bohrmaschinen mit ca. 3000 U/min bei Winkelschleifmaschinen mit ca. 9000 U/min zutrifft, die biegsamen Wellenstücke durch überbeanspruchung brechen können.According to this, it is known to use a flexible shaft for driving the grinding plate, which moreover can be stiffened by a rigid over or insertion, so that the use for flat grinding and polishing is possible with one and the same device when the shaft is rigid. It has been shown that at high loads, depending on the size of the sanding pad and high speeds, as is the case in contrast to drills with approx. 3000 rpm and angle grinders with approx. 9000 rpm, the flexible shaft sections can break due to excessive stress .

Es ist nun Aufgabe der Erfindung hier eine auch bei hoher Beanspruchung und Drehzahl weniger bruchgefährdete Lösung zu schaffen.It is an object of the invention to provide a solution which is less susceptible to breakage even under high stress and speed.

Zur Lösung dieser Aufgabe kennzeichnet sich der Schleif- oder Polierteller entsprechend Anspruch 1. Dabei wird durch Festziehen der Topfhülse eine Versteifung erreicht.To solve this problem, the grinding or polishing plate is characterized according to claim 1. Stiffening is achieved by tightening the cup sleeve.

Zur Lösung dieser Aufgabe kann sich der Schleif- oder Polierteller auch entsprechend Anspruch 2 kennzeichnen, wobei ebenfalls durch Festziehen der Schraubmutter eine Versteifung erreicht wird.To solve this problem, the grinding or polishing plate can also be characterized according to claim 2, stiffening also being achieved by tightening the screw nut.

In beiden Fällen wird in überraschender Weise neben höherer Bruchsicherheit eine elastischere und in der Fertigung billigere Ausführung erreicht.In both cases, surprisingly, in addition to greater resistance to breakage, a more elastic design that is cheaper to manufacture is achieved.

In der Zeichnung sind beispielsweise zwei bevorzugte Ausführungsformen eines Schleif- oder Poliertellers gemäß der Erfindung dargestellt und nachfolgend beschrieben und zwar zeigen:

  • Figur 1 und 2 die Darstellung der ersten Ausführung eines Schleif- bzw. Poliertellers mit flexiblem und starrem Anschluß am Antriebsfutter und
  • Figur 3 und 4 die Darstellung der zweiten Ausführung eines Schleif- bzw. Poliertellers mit flexiblem und starrem Anschluß am Antriebsfutter.
In the drawing, for example, two preferred embodiments of a grinding or polishing plate according to the invention are shown and described below, namely:
  • Figures 1 and 2 the representation of the first embodiment of a grinding or polishing plate with flexible and rigid connection to the drive chuck and
  • Figures 3 and 4 the representation of the second embodiment of a grinding or polishing plate with flexible and rigid connection to the drive chuck.

Wie aus der Zeichnung in Figur 1 und 2 ersichtlich ist, besteht der Schleif- oder Polierteller nach dem ersten Ausführungsbeispiel aus dem Plattenteller 1 aus hartem Kunststoff insbesondere aber aus Stahl mit unter Zwischenlage einer Gummiplatte 1a aufgebrachtem Schleif-oder Polierbelag 2, welcher beispielsweise mittels Klettverschluß lösbar befestigt ist. Der zylindrische Elastomerpuffer 3 aus Kunststoff oder Gummi ist hier einerseits beim Plattenanschluß am Befestigungsflansch 4 mit Außengewinde 5 zum Aufbringen einer Topfhülse 6 anvulkani- ;iert, wobei der Befestigungsflansch 4 einen Schraubstutzen 7 zum Aufspannen des Plattentellers 1 mit Mittelbohrung 8 und Gegenmutter 9 besitzt, während andererseits am Elastomerpuffer 3 ein Flansch 10 mit Einspannschaft 11 zum Anschluß am Antriebsfutter 12 anvulkanisiert ist.As can be seen from the drawing in FIGS. 1 and 2, the grinding or polishing plate according to the first exemplary embodiment consists of the platter 1 made of hard plastic, but in particular of steel with a grinding or polishing covering 2 applied with the interposition of a rubber plate 1a, which, for example, by means of a Velcro fastener is releasably attached. The cylindrical elastomer buffer 3 made of plastic or rubber is vulcanized here on the one hand at the plate connection to the mounting flange 4 with external thread 5 for applying a pot sleeve 6, the mounting flange 4 having a screw connection 7 for clamping the turntable 1 with telbohrung 8 and lock nut 9 has, while on the other hand on the elastomer buffer 3, a flange 10 with clamping shaft 11 is vulcanized for connection to the drive chuck 12.

Die Topfhülse 6 besitzt am offenen Ende ein Innengewinde 13 passend zum Außengewinde 5 am Befestigungsflansch 4 und weist am anderen Ende einen Boden 14 mit einer Mittelöffnung 15 zwecks Anlage am Flansch 10 des Einspannschaftes auf. Hierbei weist, wie ersichtlich, der Elastomerpuffer 3 abhängig vom Durchmesser des Plattentellers 1 einen wesentlich größeren Durchmesser als der Einspannschaft 11 auf, was zu guter Stabilisierung und hoher Lebensdauer bei Schleif- und Polierarbeiten auch im höchsten Drehzahlbereich führt.The pot sleeve 6 has at the open end an internal thread 13 matching the external thread 5 on the mounting flange 4 and has a bottom 14 at the other end with a central opening 15 for abutment against the flange 10 of the clamping shaft. Here, as can be seen, the elastomer buffer 3, depending on the diameter of the turntable 1, has a much larger diameter than the clamping shaft 11, which leads to good stabilization and a long service life during grinding and polishing work even in the highest speed range.

Zum Anbringen bzw. Abnehmen der topfförmigen Hülse 6 weist diese einen geriffelten bzw. abgeflachten Außenrand 16 auf. Ohne diese (6) ist entspr. Figur 1 der Plattenteller 1 für das Flachschleifen und Polieren flexibel anlegbar, so daß einseitige Schleifeindrücke vermieden werden. Bei aufgebrachter Topfhülse 6 ist der Plattenteller 1 hingegen vor dem Festziehen zwischen Grenzen, welche auch von der Größe der Mittelöffnung 15 im Boden 14 und dem Durchmesser des Einspannschaftes 11 abhängig sind, beweglich und nach dem Festziehen der Hülse 6 starr mit dem Antriebsfutter 12 verbunden, wie dies für ein einwandfreies Kantenschleifen u.a. erwünscht ist.To attach or remove the pot-shaped sleeve 6, this has a corrugated or flattened outer edge 16. Without this (6), according to FIG. 1, the turntable 1 can be flexibly applied for surface grinding and polishing, so that one-sided loop impressions are avoided. With the pot sleeve 6 attached, however, the turntable 1 is movable before tightening between limits, which also depend on the size of the central opening 15 in the base 14 and the diameter of the clamping shaft 11, and is rigidly connected to the drive chuck 12 after the sleeve 6 has been tightened, like this for a perfect edge grinding among other things is desired.

Nach der Zeichnung in Figur 3 und 4 zeigt das zweite Ausführungsbeispiel einen Schleif- und Polierteller ebenfalls bestehend aus dem Plattenteller 17 aus hartem Kunststoff, insbesondere aber aus Stahl mit unter Zwischenlage einer Gummiplatte 17a aufgebrachtem Schleif-oder Polierbelag 18, welcher beispielsweise mittels Klettverschluß lösbar befestigt ist. Der Einspannschaft 19 zum Einspannen im Antriebsfutter 20 ist hier am anderen Ende von einem Elastomerpuffer 21 aus Kunststoff oder Gummi umgeben und zwar ist dieser (21) anvulkanisiert und mit einer Metallhülse 22 umgeben, ebenfalls anvulkanisiert, welche zum Plattenanschluß ein Außengewinde 23 aufweist, auf das der Plattenteller 17 mit seinem Innengewinde 24 aufgeschraubt ist.According to the drawing in FIGS. 3 and 4, the second exemplary embodiment shows a grinding and polishing plate likewise consisting of the platter 17 made of hard plastic, but in particular made of steel with a grinding or polishing covering 18 applied with the interposition of a rubber plate 17a, which, for example, is detachably fastened by means of a Velcro fastener is. The clamping shaft 19 for clamping in the drive chuck 20 is here surrounded at the other end by an elastomeric buffer 21 made of plastic or rubber, and this is (21) vulcanized and surrounded with a metal sleeve 22, also vulcanized, which has an external thread 23 for the plate connection, on which the turntable 17 is screwed on with its internal thread 24.

Zur Versteifung ist hier eine Mutter 25 auf dem Gewinde 25a des Einspannschaftes 19 gegen die Hülse 22 des Elastomerpuffers 21 schraubbar. Der Einspannschaft 19 kann hierbei andererseits vom Elastomerpuffer 21 einen Endflansch 26 zur Gegenanlage an der Hülse 22 besitzen. Zur Montage von oben ist der Flansch 26 so zurückgesetzt, daß er durch das Außengewinde 23 der Platte 17 bringbar'und bei Anzug der Schraube 25 am Ende der Hülse 22 anlegbar ist. Bei größerer Flanschausbildung 26 kann dieser auch von unten montierbar sein, wofür. dieser (26) auf einem Endgewinde am Einspannschaft 19 aufgeschraubt und fest verklebtwird.For stiffening, a nut 25 can be screwed onto the thread 25a of the clamping shaft 19 against the sleeve 22 of the elastomer buffer 21. The clamping shaft 19 can, on the other hand, have an end flange 26 from the elastomer buffer 21 for mating with the sleeve 22. For assembly from above, the flange 26 is set back so that it can be brought through the external thread 23 of the plate 17 and can be put on at the end of the sleeve 22 when the screw 25 is tightened. With a larger flange formation 26 , this can also be mounted from below, for which purpose. this (26) screwed onto an end thread on the clamping shaft 19 and firmly glued w ir d .

Beim Anzug der Mutter 25 entfällt der Abstand 26a nach Fig. 3, sodaß eine feste Verspannung entsprechend Figur 4 erfolgt. Hierdurch wird, wie in Fig. 4 dargestellt ist, gegenüber Fig. 3 eine starre Festlegung des Plattentellers 17 ermöglicht. Der anvulkanisierte Elastomerpuffer 21 weist zum besseren Anzug bei der Festlegung mittels Mutter 25 an beiden Stirnseiten je eine Ringnut 27 bzw. 28 auf. Mit dieser zweiten Ausführung läßt sich die erfindungsgemäße Aufgabe überdies noch optimaler und sicherer lösen.When the nut 25 is tightened, the distance 26a is eliminated Fig. 3, so that a fixed bracing takes place according to Figure 4. As a result, as is shown in FIG. 4, a rigid fixing of the turntable 17 is made possible in comparison with FIG. 3. The vulcanized elastomer buffer 21 has an annular groove 27 or 28 on both ends for better tightening when fixed by means of a nut 25. With this second embodiment, the task according to the invention can also be achieved in an even more optimal and reliable manner.

Schließlich ist in Kombination zwischen dem ersten und zweiten Ausführungsbeispiel (Fig. 2 und 4) möglich, daß der Endflansch 10 und Elastomerpuffer 3 von einer topfförmigen Hülse 6 umgeben ist, die einer Ringanlage am Befestigungsflansch 4 aufsteckbar und vorzugsweise mittels Schraubmutter 25 am Gewindeschaft 25a zu halten ist.Finally, in combination between the first and second exemplary embodiment (FIGS. 2 and 4) it is possible for the end flange 10 and elastomer buffer 3 to be surrounded by a cup-shaped sleeve 6 which can be plugged onto a ring system on the fastening flange 4 and preferably by means of a screw nut 25 on the threaded shaft 25a hold is.
