Description
Mähmesserschleifmaschine. Gegenstand der Erfindung ist eine Näh messerschleifmaschine, die das; eingespannte Mähmesser auf einem Schleifstein automa tisch vor- und rückwärts bewegt und gleich zeitig zwei Schneiden schleift. In der Zeich nung ist der Erfindungsgegenstand beispiels weise dargestellt, und zwar zeigt: Abb. 1 die Mähmesserschleifmaschine von der Seite, und Abb. 2' die Draufsicht dazu; Abb. 3 zeigt eine Teilansicht einer etwas abgeänderten Mähmesserschleifmaschine. Die Spannbacken<I>a</I> und b sind bei<I>p</I> klappbar miteinander verbunden, so dass durch Wirkung eines Exzenterhebels c das zu schleifende Mähmesser zwischen den Backen festgeklemmt werden kann.
Die Backe a ist wiederum am freien Ende eines Schwingarmes e angelenkt, der auf der auf dem Hauptrahmen f der Maschine gelagerten Welle<I>h</I> festsitzt. Auf der Welle<I>h</I> ist ferner ein Hebel g drehbar gelagert, auf den .die über das Kegelradgetriebe 1, m vom Schleif steinantrieb aus angetriebene Exzenter scheibe i einwirkt und der seine Bewegung durch . die einstellbare Schraube k dem Schwingarme e. mitteilt und dadurch die Backen a, b vor- und rückwärts bewegt.
Die verstellbare Schraube k dient zur Feinein stellung des, Schleifhubes und zur Nachstel lung bei sich abnützendem Schleifstein. Bei. der Ausführungsvariante nach Abb. 3 erfolgt .der Antrieb der Exzenterscheibe i unter Ver mittlung des. Stirnräderpaares n, o. Zur Er zielung des gleichzeitigen Schleifens zweier Schneiden ist der Schleifstein am Umfang firstförmig ausgebildet.
Mower knife sharpening machine. The invention is a sewing knife grinding machine that; Clamped mower blades are automatically moved back and forth on a grindstone and simultaneously grinds two cutting edges. In the drawing, the subject matter of the invention is shown by way of example, namely: Fig. 1 shows the mower knife grinding machine from the side, and Fig. 2 'shows the top view thereof; Fig. 3 shows a partial view of a somewhat modified knife sharpening machine. The clamping jaws <I> a </I> and b are hingedly connected to each other at <I> p </I>, so that the cutting knife to be ground can be clamped between the jaws by the action of an eccentric lever c.
The jaw a is in turn articulated to the free end of a swing arm e, which is firmly seated on the shaft <I> h </I> mounted on the main frame f of the machine. A lever g is also rotatably mounted on the shaft, on which the eccentric disk i, driven by the bevel gear 1, m from the grinding stone drive, acts and which controls its movement. the adjustable screw k the swing arm e. communicates and thereby moves the jaws a, b back and forth.
The adjustable screw k is used for fine adjustment of the grinding stroke and for readjustment when the grinding stone wears out. At. the variant according to Fig. 3 takes place .the drive of the eccentric disk i mediated by the. pair of spur gears n, o. In order to achieve the simultaneous grinding of two cutting edges, the grindstone is designed in the shape of a ridge on the circumference.
