Description
Die Erfindung bezieht sich auf ein mechanisch angetriebenes. Schabewerkzeug mit geradlinig hin und her gehender Bewegung der Arbeitsspindel.The invention relates to a mechanically driven. Scraping tool with rectilinear reciprocating movement of the work spindle.
Zum genauen Einschaben von MetallfLächen aller Art sind mechanisch angetriebene Schabewerkzeuge bekanntgeworden, bei welchen mittels Antriebes durch biegsame Welle unter Verwendung eines Umlenkungsgetriebes die Schabeklinge in ähnlicher Ausführung wie die Handschabeklinge in rascher Folge mechanisch geradlinig hin und her bewegt wird. Die Schabeklinge ist bei diesen bekannten Werkzeugen in der Arbeitsspindel fest eingespannt und bleibt in ihrer Lage zum Werkzeug immer unverändert.For precise scraping into metal surfaces all kinds of mechanically driven scraping tools have become known in which by means of a flexible shaft drive using a deflection gear the scraper blade in a similar design as the hand scraper blade in quick succession is moved back and forth mechanically in a straight line. The scraper blade is well known in these Tools are firmly clamped in the work spindle and remain in their position for Tool always unchanged.
Es hat sich nun gezeigt, daß ein Schaben nach dieser Methode feine Haarrisse hinterläßt, da das abzuhebende Material gleichermaßen weggehobelt oder weggestoßen wird. Der Erfindung liegt nun eine Schabeklinge zugrunde, bei welcher das abzuhebende Material nicht weggehobelt, sondern weggeschnitten wird, um Haarrisse zu vermeiden.It has now been shown that scraping using this method leaves fine hairline cracks, because the material to be lifted is planed or pushed away in the same way. The invention now resides in a scraper blade where the material to be lifted is not planed away, but cut away to avoid hairline cracks.
Da die geradlinig hin und her gehende ' Bewegung an sich festliegt, kann ein Wegschneiden von Material nur dadurch erzielt werden, daß die Schabeklinge an der Schneidkante abgerundet ist und sich während des Hubes um einen gewissen "Winkel zu der Antriebsspindel verschwenkt. Der Schwenkungswinkel wird bestimmt durch die Rundung, deren Schneide in Art einer Messerbewegung über das zu bearbeitende Material weggeht. Dies wird nun erfindungsgemäß dadurch erreicht, daß in die Arbeitsspindel eine Nut eingefräst ist, in welche ein in dem Gehäuse fest eingesetzter Stift eingreift.Since the straight back and forth movement is fixed in itself, it can be cut away of material can only be achieved by keeping the scraper blade at the cutting edge is rounded and during the stroke at a certain "angle to the Drive spindle pivoted. The swivel angle is determined by the rounding, whose cutting edge moves over the material to be processed in the manner of a knife movement. This is now according to the invention achieved in that a groove is milled into the work spindle, in which one in the Housing firmly inserted pin engages.
Das in die Arbeitsspindel eingesetzte Werkzeug macht demnach nicht nur eine hin und her gehende Bewegung, sondern gleichzeitig eine Schwenkbewegung.The tool used in the work spindle therefore doesn't just make one thing forward movement, but at the same time a pivoting movement.
Damit nun die Schneidkante der Schabeklinge in jeder Stellung der Arbeitsspindel auf der zu bearbeitenden Fläche aufliegt, kann die Form der Schabeklinge entweder, wenn rechteckiges Material verwendet wird, vorn abgerundet sein, oder aber die Schabeklinge muß, wenn die Fläche, in welcher die Schneidkante liegt, genau senkrecht zur Achse der Schabeklinge geschnitten ist, eine ballige Form haben. Auf jeden Fall muß in jeder Stellung der Schabeklinge die Schneidkante bzw. deren Krümmung tangential auf der Arbeitsfläche aufliegen.So now the cutting edge of the scraper blade in every position of the work spindle rests on the surface to be processed, the shape of the scraper blade can either if rectangular material is used, it should be rounded at the front, or the scraper blade must, if the surface in which the cutting edge lies is cut exactly perpendicular to the axis of the scraper blade, a have a convex shape. In any case, the cutting edge must be in every position of the scraper blade or their curvature lie tangentially on the work surface.
Damit nun beim unsorgfältigen Aufsetzen der Schabeklinge kein Beschädigen durch scharfe Ecken an den beiden Enden der Schneidkante eintreten kann, wird erfindungsgemäß noch vorgesehen, diese Ecken abzurunden.So that if the scraper blade is not placed carefully, there is no damage sharp corners can occur at the two ends of the cutting edge, is according to the invention still intended to round off these corners.
