Description
Die Erfindung betrifft einen Schleifteller für mit der Hand gehaltene, motorgetriebene Schleifmaschinen, gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a sanding pad for hand-held, motor-driven grinding machines, according to the preamble of claim 1.
Ein derartiger Schleifteller geht aus
Bei üblichen Schleiftellern weist die Innengewindeanordnung einen verhältnismäßig kleinen Durchmesser auf und das zugeordnete maschinenseitige Anschlußteil wird von einem Gewindebolzen entsprechenden Durchmessers gebildet.In conventional grinding plates, the internal thread arrangement has a relatively small diameter and the associated machine-side connecting part is formed by a threaded bolt of corresponding diameter.
Bei diesen Schleiftellern besteht die Gefahr, dass sie keine exakt plan verlaufende Schleifbewegung ausführen sondern sozusagen mit einem Planschlag und somit ungleichmäßig umlaufen. Dies kann das Arbeitsergebnis beeinträchtigen.With these sanding discs there is the danger that they do not execute a precisely planar grinding movement, but so to speak with a flat rate and thus unevenly circulate. This can affect the work result.
Der vorliegenden Erfindung liegt deshalb die Aufgabe zugrunde, einen Schleifteller zu schaffen, der beim Betrieb möglichst plan umläuft.The present invention is therefore an object of the invention to provide a sanding pad that rotates as plan as possible during operation.
Diese Aufgabe wird durch einen Schleifteller gemäß der technischen Lehre des Anspruchs 1 gelöst.This object is achieved by a sanding pad according to the technical teaching of claim 1.
Bei dem erfindungsgemäßen Schleifteller weist die Innengewindeanordnung, bezogen auf den Außendurchmesser des Schleiftellers, einen Mindestdurchmesser auf, von dem ab die Schleifbewegung des Schleiftellers, wie Versuche gezeigt haben, zumindest im wesentlichen schlagfrei verläuft.In the sanding pad according to the invention, the internal thread arrangement, based on the outer diameter of the sanding pad, has a minimum diameter from which the grinding movement of the sanding pad, as tests have shown, proceeds at least substantially without impact.
Ferner kann ein mehrgängiges Gewinde im Vergleich zu einem eingängigen Gewinde aufgrund seiner größeren Steigung bei gleicher Materialbelastung ein größeres Drehmoment übertragen. Daher kann man den Schleifteller stärker festziehen bzw. bei gleich starkem Festzieh-Drehmoment wie bei einem eingängigen Gewinde leichter wieder abschrauben.Furthermore, a multi-start thread can transmit a larger torque compared to a single-thread because of its larger pitch with the same material load. Therefore, you can tighten the sanding plate stronger or unscrew with the same strong tightening torque as a catchy thread easier again.

Die aus
Der Maschinenkopf 2 enthält eine vom Antriebsmotor her antreibbare Arbeitseinheit, die eine rechtwinkelig zur Motorwelle verlaufende und über ein nicht dargestelltes Umlenkgetriebe von dieser her angetriebene Antriebswelle 4 aufweist, an deren unteres Ende exzentrisch zu ihrer Wellenachslinie 5 ein parallel zur Antriebswelle 4 verlaufender Kurbelzapfen 6 angesetzt ist. Die zur Wellenachslinie 5 exzentrische Zapfenachslinie des Kurbelzapfens 6 ist mit der Bezugsziffer 5 bezeichnet.The machine head 2 includes a drivable by the drive motor forth working unit having a perpendicular to the motor shaft and driven via an unillustrated reversing gear from this forth drive shaft 4, at its lower end eccentric to its shaft axis 5 a parallel to the drive shaft 4 extending crank
An dem Kurbelzapfen 6 ist über ein Drehlager 7 ein Anschlußteil 8 drehbar gelagert, das beim Betrieb eine um die Wellenachslinie 5 kreisende Bewegung ausführt. Das Anschlußteil 8 enthält einen nach unten hin offenen Hohlraum 9, in dem ein Unwucht-Ausgleichskörper 10 angeordnet ist, der drehfest mit dem Kurbelzapfen 6 verbunden ist und von diesem zur Seite der Wellenachslinie 5 hin absteht, so dass sich eine insgesamt ausgewuchtete Anordnung ergibt.On the
Das Anschlußteil 8 bildet einen nach unten hin abstehenden Gewindeabschnitt 11 mit einer Außengewindeanordnung 12, so dass auf den Gewindeabschnitt 11 ein Schleifteller 13 aufschraubbar ist. Der Schleifteller 13 weist eine an der Schleifteller-Oberseite 14 offene, zentral angeordnete Befestigungsausnehmung 15 mit einer Innengewindeanordnung 16 auf, die mit der Außengewindeanordnung 12 des Anschlußteils 8 zusammenwirkt, so dass der Schleifteller 13 mit seiner Innengewindeanordnung 16 lösbar auf die Außengewindeanordnung 12 des Anschlußteils 8 aufgeschraubt werden kann. Im aufgeschraubten Zustand führt der Schleifteller 13 beim Betrieb eine der kreisenden Bewegung des Anschlußteils 8 entsprechende Schleifbewegung aus.The connecting part 8 forms a downwardly projecting threaded
Der Schleifteller 13 weist eine kreisrunde Gestalt auf. Er wird im dargestellten Falle von einem Schleifteller-Oberteil 17 aus starrem Material, insbesondere Kunststoffmaterial, und aus einem unten an das Oberteil 17 angesetzten Schleifteller-Unterteil 18 aus nachgiebigem Material, insbesondere Schaumkunststoff, gebildet, wobei an der Unterseite des Schleifteller-Unterteils 18 ein schleifblattartiges Schleifmittel auswechselbar befestigt werden kann, mit dem die Schleifbearbeitung des jeweiligen Werkstücks ausgeführt wird. Die Befestigung des Schleifmittels kann mittels eines Klettverschlusses erfolgen. Hierzu ist an der Unterseite des Schleifteller-Unterteils 18 ein Klettenhaftbelag 19 angeordnet. Das nicht dargestellte Schleifmittel weist einen mit dem Klettenhaftbelag 19 zusammenwirkenden Klettenhaftbelag auf.The
Das Schleifteller-Oberteil 17 überdeckt das Schleifteller-Unterteil 18 tellerartig. Dabei steht das Unterteil 18 am Umfang über das Oberteil 17 vor, wobei sich das Unterteil 18, ausgehend vom Oberteil 17, nach unten hin allmählich vergrößert, so dass sich ein vom Oberteil 18 nicht abgedeckter, nach unten außen hin schräg verlaufender Randbereich 20 des Unterteils 17 ergibt.The sanding pad
Die Befestigungsausnehmung 15 wird von einer dosenartigen, in das Schleifteller-Unterteil 18 eingreifenden Vertiefungspartie 21 des Schleifteller-Oberteils 17 gebildet, an deren Rand die Innengewindeanordnung 16 ausgebildet ist. Nach unten hin ist die Vertiefungspartie 21 durch eine Bodenwand 22 abgeschlossen.The mounting recess 15 is formed by a can-like, engaging in the
Die Innengewindeanordnung 16 wird von einem mehrgängigen Gewinde mit mindestens zwei winkelversetzt zueinander angeordneten Gewindegängen gebildet. Zweckmäßigerweise handelt es sich um ein dreigängiges Gewinde mit drei Gewindegängen 23, 24, 25, deren Anfänge in der Draufsicht gemäß
Die Außengewindeanordnung 12 des Anschlußteils 8 ist entsprechend mehrgängig ausgebildet. In
Ferner ist vorgesehen, dass das Durchmesserverhältnis zwischen dem Durchmesser D1 der Innengewindeanordnung 16 und dem Außendurchmesser D2 des Schleiftellers 13 mindestens etwa 0,25 beträgt. Mit dem Außendurchmesser D2 des Schleiftellers 13 ist dessen Nenndurchmesser gemeint, das heißt sein größter Durchmesser, der beim Ausführungsbeispiel an der Unterseite des Schleifteller-Unterteils 18 auftritt. Der Durchmesser D1 der Innengewindeanordnung 16 beträgt also mindestens ein Viertel des Außendurchmessers D2 des Schleiftellers 13.It is further provided that the diameter ratio between the diameter D1 of the
Zweckmäßigerweise liegt das genannte Durchmesserverhältnis im Bereich zwischen etwa 0,25 bis 0,5, wobei der Bereich zwischen etwa 0,3 und 0,4 besonders vorteilhaft ist.Conveniently, said diameter ratio is in the range between about 0.25 to 0.5, the range between about 0.3 and 0.4 being particularly advantageous.
Der Durchmesser D1 der Innengewindeanordnung 16 und dementsprechend auch der Durchmesser der Außengewindeanordnung 12 des maschinenseitigen Anschlußteils 8 ist somit, bezogen auf den Außendurchmesser D2 des Schleiftellers 13, verhältnismäßig groß. Dies ergibt bei festgeschraubtem Schleifteller 13 nicht nur einen stabilen und festen Halt sondern vor allem auch eine praktisch exakt plan verlaufende Schleifbewegung.The diameter D1 of the
Der Schleifteller 13 weist an seiner Oberseite eine Anlagefläche 26 ringartiger Gestalt auf, die um die Mündung der Befestigungsausnehmung 15 herum verläuft und beim Aufschrauben des Schleiftellers 13 an einer maschinenseitigen Gegenfläche 27 zur Anlage gelangt. Der Schleifteller 13 wird bei seinem Aufschrauben gegen diese Gegenfläche 27 verspannt. Die Gegenfläche 26 wird von der Unterseite eines Ringbundes 28 des Anschlußteils 8 gebildet, der am oberen Ende des Gewindeabschnitts 11 nach radial außen hin absteht.The
Der Schleifteller 13 bildet ferner an seiner Oberseite eine zur Befestigungsausnehmung 15 konzentrische, größeren Durchmesser als die Anlagefläche 26 aufweisende Steckausnehmung 29, in die eine maschinenseitige Ringpartie 30 eingreift, so dass eine Zentrierung stattfindet. Die Ringpartie 30 wird beim Ausführungsbeispiel von dem Ringbund 28 des Anschlußteils 8 gebildet. Die Anlagefläche 26 bildet den Boden dieser Steckausnehmung 29.The
Der Schleifteller 13 weist Durchtrittsöffnungen 31 auf, die einerseits an der Unterseite und andererseits an der Oberseite des Schleiftellers 13 münden. Dabei sind die oberseitigen Mündungen 32 der Durchtrittsöffnungen 31 radial außerhalb der Befestigungsausnehmung 15 angeordnet und dabei um die Befestigungsausnehmung 15 herum verteilt. Diese Durchtrittsöffnungen 31 dienen zur Absaugung des bei der Schleifbearbeitung entstehenden Staubes. Hierzu wird in üblicher Weise ein Saugstrom erzeugt, der den vom Werkstück abgesaugten Schleifstaub mitnimmt. Solche Staubabsaugeinrichtungen sind allgemein üblich, so dass sich eine weitere diesbezügliche Beschreibung erübrigt.The
Aus der Zeichnung ist ferner ersichtlich, dass die oberseitigen Mündungen 32 der Durchtrittsöffnungen 31 in radialer Richtung zumindest im Wesentlichen innerhalb der Kreislinie 33 angeordnet sind, die mittig zwischen der Innengewindeanordnung 16 und dem Außenumfang des Schleiftellers 13 verläuft. Die von der genannten Kreislinie 33 nach radial innen hin ausgehende und die oberseitigen Mündungen 32 der Durchtrittsöffnungen 31 enthaltende Ringfläche 34 des Schleiftellers 13 ist beim Ausführungsbeispiel leicht kegelig angestellt.It can also be seen from the drawing that the upper-
Abschließend wird noch darauf hingewiesen, dass sich der beschriebene Schleifteller nicht nur für Exzentertellerschleifer sondern auch für Schleifmaschinen mit rotierendem Schleifteller oder auch für solche Maschinen eignet, bei denen der kreisenden Bewegung eine Rotationsbewegung überlagert ist.Finally, it should be noted that the sanding plate described is not only suitable for Eccentric disc grinder but also for grinding machines with rotating sanding pad or for such machines in which the circular motion is superimposed on a rotational movement.
