KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Die Erfindung bezieht sich auf Bildhauer-Kopiermaschinen mit Parallelogrammführung, bei denen das Werkzeug auf der Verlängerung einer Parallelogrammseite über den einen der Gelenkpunkte hinaus, in welchen die angrenzenden Parallelogrammseiten angreifen, angeordnet ist. Bei derartigen Maschinen hat man bisher zum Ausgleich des Werkzeuggewichtes zwei Gegengewichte angewendet, eines,The invention relates to sculptor copying machines with parallelogram guidance, where the tool is on the extension of one side of the parallelogram over one of the Articulation points in which the adjacent parallelogram sides engage, is arranged. In machines of this type, it has hitherto been necessary to compensate for the weight of the tool two counterweights applied, one,
ίο welches das Werkzeuggewicht in bezug auf den genannten einen Gelenkpunkt ausglich, und ein zweites, welches das Werkzeuggewicht und das erste Gegengewicht in bezug auf den festen Drehpunkt des Parallelogramms ausglich. ίο which the tool weight in relation to counterbalanced the said one pivot point, and a second which the tool weight and counterbalancing the first counterweight with respect to the fixed pivot point of the parallelogram.
Gemäß der Erfindung wird der Ausgleich des Werkzeuggewichtes durch ein einziges Gegengewicht bewirkt, welches, vom Werkzeug aus gesehen, jenseits der den festen Drehpunkt des Parallelogramms enthaltenden Parallelogrammseite, und zwar mit dem Schwerpunkt an einer auf der Verbindungsgeraden des Werkzeuglagerpunktes mit dem festen Drehpunkt des Parallelogramms gelegenen Stelle des Parallelogramms angeordnet ist.According to the invention, the compensation of the tool weight by a single Counterweight causes which, seen from the tool, beyond the fixed The pivot point of the parallelogram side containing the parallelogram, namely with the Focus on one of the straight lines connecting the tool support point with the fixed point of rotation of the parallelogram located point of the parallelogram is.
Auf der Zeichnung ist die Kopiermaschine schematisch im Aufriß dargestellt. B, C, D, E ist das Führungsparallelogramm. Auf der Verlängerung von B1C in A ist das Werkzeug W in bekannter Weise um den Punkt A schwingend untergebracht. Unter »Werkzeug« ist hier nicht nur das eigentliche, Material abtrennende Messer, sondern auch seine Spindel nebst Lagerung und der Taster zu verstehen. Sind mehrere Werkzeuge vorhanden, so gehören auch die Verbindungen der Werkzeugspindellagerungen mit zu dem Begriff »Werkzeug«. In Punkt D befindet sich das Ausgleichsgewicht G. F ist der feste Drehpunkt der Parallelogrammführung. Er liegt auf der Parallelogrammseite B, E. Wenn Gleichgewicht in jeder Werkzeuglage stattfinden soll, so muß der Drehpunkt F auf der gestrichelt angedeuteten Verbindungsgeraden des Werkzeuglagerpunktes A mit dem Gegengewichtsschwerpunkt liegen, der bei der dargestellten Ausführung mit dem Gelenkpunkt D zusammenfällt. In the drawing, the copier is shown schematically in elevation. B, C, D, E is the guide parallelogram. On the extension of B 1 C in A , the tool W is accommodated swinging around point A in a known manner. The term »tool« is to be understood here not only as the actual knife which separates the material, but also its spindle, bearing and button. If there are several tools, the connections between the tool spindle bearings also belong to the term »tool«. At point D there is the counterweight G. F is the fixed pivot point of the parallelogram guide. It lies on the parallelogram side B, E. If equilibrium is to take place in every tool position, the point of rotation F must lie on the straight line connecting the tool bearing point A with the counterweight's center of gravity, which in the embodiment shown coincides with the pivot point D.
