St8danordning for slipning av sk8rdeniaskinsknivar. Support device for sharpening cutting machine knives.

I bifogade ritning anger fig. 1 stodanordningen sedd framifran, fig. 2 sedd frail sidan och fig. 3 sedd uppifran. Fig. 4 visar en detalj i storre skala. In the accompanying drawing, Fig. 1 shows the standing device seen from the front, Fig. 2 seen from the side and Fig. 3 seen from above. Fig. 4 shows a detail on a larger scale.

Stativet 1, besta.ende ay en plat och tvenne vinIceljarn, fastes vid en slipho (slipbock) exempelvis medelst tvenne bultar 2. En hay-arm 3 är vridbar omkring bulten 4. Genom en stoppskruv 5 och ett sparsegment i stativet 1 kan havarmen 3 fastgoras i onskat lige. Havarmen 3 hestar av tvenne upptill utatbed da plattjarn, ett pa -vardera sidan om stativets plat. I den vinkel, som Midas av de tvenne utatbojda jarnen, är en hylsa 6 fastsvetsad. Genom denna hylsa lOper en tapp 7, vilken uppbar den nedat gaffelformat Whitdade och om tappen ledande havarmen S. Upptill ãr havarmen 8 forsedd med ett fastsvetsat rot. 9. Styrstangen 10 loper genom roret 9. Pa styrstangen arc tre armar 11 fastsvetsade. For att armarna 11 obehindrat skola kunna glida forbi roret 9 är detta senare forsett med ett genomgdende spar, vilket visas i fig. 4. Armarna 11 upphara skordemaskinskniven, som fastes medelst klamkolvar och skruv med vingmutter. The frame 1, consisting of a flat and two winch iron, is fastened to a grinding hook (grinding buck) for example by means of two bolts 2. A hay arm 3 is rotatable about the bolt 4. Through a stop screw 5 and a spare segment in the frame 1 the lever arm 3 can fastgoras in onskat straight. The sea arm 3 horses of the two at the top utatbed da flat iron, one on each side of the stand plate. At the angle at which Midas is bent by the two outwardly bent yarns, a sleeve 6 is welded. Through this sleeve runs a pin 7, which carried the lower fork-shaped Whitdade and about the pin leading the sea arm S. At the top, the sea arm 8 is provided with a welded root. 9. The handlebar 10 runs through the tube 9. On the handlebar three arms 11 are welded. In order for the arms 11 to be able to slide past the rudder 9 unhindered, this latter is provided with a continuous groove, which is shown in Fig. 4. The arms 11 raise the harvester knife, which is fastened by means of clamping pistons and screw with wing nut.

Genom ,anordningen blir del mojligt att Ulla en konstant vinkel for slipeggen. Vidare mojliggores genom hivarmen 8 den ringa forskj utning av styrstangen och darmed aven av skOrdemaskinskniven som erfordras, fi3r aft erhalla en plan slipyta pa kni-ven, oaktat slipstenens motsvarande yta är bOjd. Through, the device becomes part possible to Ulla a constant angle for the grinding edge. Furthermore, the low displacement of the guide rod and thus also of the cutting knife required by the lever 8 is made possible in order to obtain a flat grinding surface on the knife, notwithstanding that the corresponding surface of the grinding stone is curved.

Den ovan angivna stodanordningen ar anvandbar aven for det fall aft slipkroppen (slipsten, smargelskiva ,etc.) har vertikal axel. Det blir dã mojligt att utfora slipningen pa slipkroppens horisontala och plana yta. The above-mentioned support device can also be used in the case where the grinding body (grindstone, emery plate, etc.) has a vertical axis. It then becomes possible to perform the grinding on the horizontal and flat surface of the grinding body.

Claims

1. Claim claim: Support device for grinding harvester knives, characterized in that the harvester knife is arranged to be fastened to a guide support, which is supported by an approximately one. shaft rotatable sea arm, which Or is provided partly with a knuckle joint and partly with a rudder welded to the sea arm and with a slotted groove through which the guide rod scratches.
