Abstract
tung für Werkstücke (2), insbesondere für Messer von Rasenmähern oder Häckslern, welche wenigstens zwei beabstandet zueinander angeordnete Schneidflächen (30, 32) aufweisen, enthaltend eine Haltevorrichtung (3) für das Werkstück (2) sowie eine Schleifscheibe (7), mittels welcher die Schneidflächen (30, 32) schleifbar sind. Die Schleifvorrichtung soll mit einem geringen konstruktiven Aufwand dahingehend ausgebildet werden, dass das Schleifen der Schneidflächen (30, 32) ohne Umspannen und/oder Veränderungen der Haltevorrichtung (3) durchgeführt werden kann. Zur Lösung wird vorgeschlagen, dass eine Schwenkvorrichtung (4) vorgesehen ist, mittels welcher das Werkstück (2) um eine Schwenkachse (5) schwenkbar ist, und dass die Schwenkvorrichtung (4) um eine Drehachse (22) drehbar derart angeordnet ist, dass wahlweise und/oder nacheinander die erste Schneidfläche (30) und die zweite Schneidfläche (32) mittels der Schleifscheibe (7) geschliffen werden kann.Device for workpieces (2), in particular for knives of lawn mowers or shredders, which at least two mutually spaced cutting surfaces (30, 32), comprising a holding device (3) for the workpiece (2) and a grinding wheel (7), by means of which the cutting surfaces (30, 32) are sandable. The grinding device is to be designed with a low design effort to the effect that the grinding of the cutting surfaces (30, 32) without re-clamping and / or changes of the holding device (3) can be performed. To solve it is proposed that a pivoting device (4) is provided, by means of which the workpiece (2) about a pivot axis (5) is pivotable, and that the pivoting device (4) about a rotational axis (22) is rotatably arranged such that optionally and / or successively the first cutting surface (30) and the second cutting surface (32) by means of the grinding wheel (7) can be ground.
Description
Die Erfindung bezieht sich auf eine Schleifvorrichtung für Werkstücke, insbesondere für Messer von Rasenmähern oder Häckslern.The The invention relates to a grinding device for workpieces, in particular for knives of lawnmowers or shredders.
Die mittels einer derartigen Schleifvorrichtung zu schleifenden Werkstücke enthalten im Bereich der Enden üblicherweise wenigstens zwei Schneidflächen, welche nach einer gewissen Gebrauchsdauer durch Schleifen geschärft werden müssen. Hierzu wird das Werkstück auf eine geeignete Haltevorrichtung derart aufgespannt, dass mittels einer rotierenden Schleifscheibe und bei Durchführung einer linearen Relativbewegung zwischen der Schleifscheibe und dem Werkstück zunächst die eine Schneidfläche geschliffen wird. Nachfolgend wird das Werkstück auf der Haltevorrichtung umgespannt, damit auch die zweite Schneidfläche geschliffen werden kann. Der Zeit- und Arbeitsaufwand ist hierbei nicht unerheblich.The Contain by means of such a grinding device to be sanded workpieces in the area of the ends usually at least two cutting surfaces, which must be sharpened by grinding after a certain period of use. For this becomes the workpiece clamped on a suitable holding device such that by means of a rotating grinding wheel and when performing a linear relative movement first the one cutting surface is ground between the grinding wheel and the workpiece becomes. Subsequently, the workpiece on the holding device spanned, so that the second cutting surface can be ground. The time and effort is not insignificant.
Der Erfindung liegt die Aufgabe zugrunde, die Schleifvorrichtung mit einem geringen konstruktiven Aufwand dahingehend auszubilden, dass das Schleifen der Schneidflächen ohne Umspannen und/oder Veränderungen der Haltevorrichtung durchgeführt werden kann. Die Schleifvorrichtung soll in einfacher Weise handhabbar sein und/oder mit geringem Arbeits- und/oder Montageaufwand ein funktionssicheres und/oder optimiertes Schleifen des Werkstücks ermöglichen. Ferner soll die Schleifvorrichtung einen geringen Fertigungs- und/oder Montageaufwand erfordern und in einfacher und gleichwohl sicherer Weise das Schleifen von unterschiedlich und/oder verschiedene Abmessungen aufweisenden Werkstücken problemlos ermöglichen.Of the Invention is the object of the grinding device with to design a low design effort to the effect that the grinding of the cutting surfaces without reclamping and / or changes the holding device performed can be. The grinding device should be easy to handle be and / or with low labor and / or assembly costs enable functionally reliable and / or optimized grinding of the workpiece. Furthermore, the grinding device is a small manufacturing and / or Require assembly effort and in a simple and yet safer way Do the grinding of different and / or different dimensions having workpieces easily possible.
Die Lösung dieser Aufgabe erfolgt gemäß den im Patentanspruch 1 angegebenen Merkmalen. Besondere Ausgestaltungen und Weiterbildungen sind in den Unteransprüchen sowie der Beschreibung eines besonderen Ausführungsbeispiels angegeben.The solution This task is performed according to the Claim 1 features specified. Special designs and further developments are in the dependent claims and the description a particular embodiment specified.
Die erfindungsgemäße Schleifvorrichtung wird anhand des in der Zeichnung schematisch dargestellten Ausführungsbeispiels näher erläutert, ohne dass insoweit eine Beschränkung erfolgt. Es zeigen:The inventive grinding device is based on the embodiment schematically shown in the drawing explained in more detail, without that in that respect a restriction he follows. Show it:
