Abstract
Ein Tellerschleifer weist eine beim Betrieb eine rotierende und/oder kreisende Bewegung ausführende Haltevorrichtung (7) zum lösbaren Befestigen eines Schleiftellers (8) auf. Dabei ist der Schleifteller (8) mittels einer Steck-/Drehverbindungseinrichtung nach Art einer Bajonettverbindung lösbar an der Haltevorrichtung befestigbar.A disc sander has a holding device (7) that executes a rotating and / or circular movement during operation for releasably securing a sanding disc (8). The sanding plate (8) can be releasably fastened to the holding device by means of a plug / rotary connection device in the manner of a bayonet connection.
Description
Die Erfindung betrifft einen Tellerschleifer, insbesondere Exzentertellerschleifer, mit einer beim Betrieb eine motorisch angetriebene rotierende und/oder kreisende Bewegung ausführenden Haltevorrichtung zum lösbaren Befestigen eines Schleiftellers. Die Erfindung befasst sich ferner mit einem Schleifteller für einen solchen Tellerschleifer.The The invention relates to a disc sander, in particular eccentric disc sander, with a motor driven rotating and / or during operation performing a circular movement Holding device for releasable Attaching a sanding plate. The invention is further concerned with a sanding plate for such a disc sander.
Tellerschleifer sind von Hand geführte Geräte und dienen zur schleifenden Bearbeitung von Werkstücken. Dabei kann je nach der vorzunehmenden Schleifarbeit oder im Verschleißfall ein Schleiftellerwechsel erforderlich werden. Dieses Entfernen und Anbringen des Schleiftellers sollte möglichst werkzeuglos und ohne besondere Schwierigkeiten für den Benutzer erfolgen.Tellerschleifer are hand-guided equipment and are used for grinding workpieces. there Depending on the grinding work to be performed or in case of wear Sanding pad replacement will be required. This removal and attachment The sanding plate should be as tool-free as possible and without any special difficulties for the user.
Ferner besteht bei Schleiftellern allgemein die Gefahr, dass sie keine exakt plan verlaufende Schleifbewegung ausführen sondern mit einem sogenannten Planschlag umlaufen, was das Arbeitsergebnis beeinträchtigen kann.Further there is a general risk of sanding plates that they no execute exactly plan running grinding movement but with a so-called Turn around plan, which affect the work result can.
Ausgehend hiervon liegt der Erfindung die Aufgabe zu Grunde, die Montage und Demontage des Schleiftellers möglichst einfach und dabei werkzeuglos zu gestalten. Außerdem soll der Schleifteller möglichst plan umlaufen.outgoing From this, the invention is based on the object, the assembly and Disassembly of the sanding pad possible simple and tool-free design. In addition, the sanding plate as possible plan to revolve.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass der Schleifteller mittels einer Steck-/Drehverbindungseinrichtung nach Art einer Bajonettverbindung lösbar an der Haltevorrichtung befestigbar ist.These Task is inventively characterized solved, that the sanding pad by means of a plug / rotary connection device in the manner of a bayonet connection detachably fastened to the holding device is.
Beim Befestigen des Schleiftellers muss dieser lediglich in axialer Richtung an die Haltevorrichtung angesteckt und dann verdreht werden, sodass die Bajonettverbindung wirksam und der Schleifteller damit sicher gehalten wird. Das Wegnehmen des Schleiftellers erfolgt in umgekehrter Richtung. Es ergibt sich eine sehr einfache Handhabung. Irgendwelche Werkzeuge werden nicht benötigt.At the Fixing the sanding plate must this only in the axial direction be attached to the holding device and then rotated so that the Bayonet connection effective and held the sanding pad so safe becomes. The removal of the sanding plate takes place in the opposite direction. This results in a very easy handling. Any tools are not needed.
Bajonettverbindungen weisen allgemein einen verhältnismäßig großen Durchmesser auf. Dementsprechend kann auch vorliegend der Durchmesser groß bemessen werden, was den planen Umlauf des Schleiftellers begünstigt.bayonet connections generally have a relatively large diameter on. Accordingly, in the present case, the diameter can be made large be, which favors the plan circulation of the sanding plate.
Ein weiterer Vorteil besteht darin, dass eine Bajonettverbindung in axialer Richtung kurz baut. In Zusammenhang hiermit ist der erfindungsgemäße Schleifteller dadurch gekennzeich net, dass er eine von seiner beim Gebrauch dem zu schleifenden Werkstück entgegengesetzten Oberseite ausgehende, im Wesentlichen kreisförmige Steckausnehmung zum Eintauchen des Halteteils aufweist.One Another advantage is that a bayonet connection in axial direction short builds. In connection herewith is the sanding pad according to the invention characterized in that it one of his in use the to be ground workpiece opposite upper side outgoing, substantially circular plug recess for Dipping the holding part has.
Auf diese Weise findet die Bajonettverriegelung sozusagen im Inneren des Schleiftellers statt. Auf Grund der geringen axialen Länge der Steckausnehmung kann ein die Steckausnehmung enthaltendes, aus starrem Material bestehendes Oberteil des Schleiftellers verhältnismäßig flach gehalten werden, sodass ein an das Oberteil angesetztes Schleifteller-Unterteil aus elastisch verformbarem Kunststoffmaterial entsprechend dicker gemacht werden kann. Schleifteller weisen üblicherweise ein elastisches Unterteil auf, an dessen Unterseite das die Schleifbearbeitung ausführende Schleifmittel angebracht wird. Dabei erhält man durch das elastische Unterteil ein gutes Anschmiegen des Schleifmittels an das Werkstück, auch wenn dieses uneben ist.On This way, the bayonet lock finds itself inside, so to speak the sanding plate instead. Due to the small axial length of Plug recess may contain a plug-in recess, from rigid Material existing upper part of the sanding pad relatively flat be held so that an attached to the upper part sanding pad base made of elastically deformable plastic material correspondingly thicker can be made. Sanding plates usually have an elastic lower part on, on the underside of which the abrasive machining exporting abrasive is attached. It receives by the elastic lower part a good nestling of the abrasive to the workpiece, even if this is uneven.
