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.
