Description

punkt in der Mitte 13 ist bei dieser Schwenkbewegung exakt an seinem Platz geblieben.point in the middle 13 has remained exactly in place during this pivoting movement.

Das Kurbelgetriebe 10 ist als Doppelkurbelgetriebe ausgebildet, das acht Gelenke 16 bis 23 aufweist und aus zwei parallel zueinander laufenden Kurbeln 24, 25 und ebenfalls parallel zueinander gerichteten Koppelgliedern 26, 27 besteht. Der Bearbeitungskörper 5 ist so an die Gelenke 22, 23 an den Enden der Koppelglieder 26, 27, die auf der einen Seite über die Gelenke 18, 20 hinausragen, angeschlossen, daß die Verbindungslinie eine Parallele 28 zu den Kurbeln 24, 25 abgibt und durch die Mitte 13 der Bearbeitungsfläche 14 geht, die wiederum in eir.er Ebene 29 liegt, in die auch die Achsen 30, 31 der Gelenke 16, 17 fallen. Das Koppelglied 26, das näher an den Gelenken 16, 17 des Gestells 15 liegt, ist als stabiler Träger 32 ausgebildet, der das Gewicht des Bearbeitungskörpers 5 im Gelenk 22 aufnimmt, während das Koppelglied 27 lediglich eine entsprechend schwächere Führungsstange 33 abgibt. Per Träger 32 ist zwischen der Führungsstange 33 und dem Gestell 15 des Kurbelgetriebes 10 angeordnet. Die Kurbeln 24, 25 sind U-förmig mit unterschiedlich langen Schenkeln 34, 35 ausgebildet, in der Basis befinden sich jeweils die Gelenke 16, 17, die die Kurbeln 24, 25 mit dem Gestell 15 verbinden. Das Koppelglied 26 ist in beiden Schenkeln 34, 35 der Kurbeln 24, 25 gelagert (Gelenke 18, 19) für das Koppelglied 27 genügt die Lagerung jeweils in den Schenkeln 35 (Gelenke 20, 21).The crank mechanism 10 is designed as a double crank mechanism which has eight joints 16 to 23 and from two parallel cranks 24, 25 and also parallel coupling links 26, 27 consists. The processing body 5 is so on the joints 22, 23 at the ends of the coupling links 26, 27, which protrude on one side over the joints 18, 20, connected that the Connecting line is a parallel 28 to the cranks 24, 25 and goes through the center 13 of the processing surface 14, which in turn lies in a plane 29, in which the axes 30, 31 of the joints 16, 17 also fall. The coupling link 26, which is closer to the joints 16, 17 of the frame 15 is formed as a stable carrier 32 that supports the weight of the processing body 5 receives in the joint 22, while the coupling member 27 only receives a correspondingly weaker one Guide rod 33 releases. A carrier 32 is between the guide rod 33 and the frame 15 of the crank mechanism 10 is arranged. The cranks 24, 25 are U-shaped with legs of different lengths 34, 35, in the base there are each the joints 16, 17, which the cranks 24, 25 with connect the frame 15. The coupling member 26 is mounted in both legs 34, 35 of the cranks 24, 25 (Joints 18, 19) for the coupling member 27, the storage in each of the legs 35 (joints 20, 21).

Das Gestell 15 ist mit einem Ausleger 36 versehen, ar. dem eine Verstelleinrichtung 37 angreift, mit dem der Bearbeitungskörper 5 über die Kurbel 25 bewegt wird. Die Verstelleinrichtung 37 besteht in der ersten Ausführungsform (F i g. 1 bis 3) aus einer Gewindestange 38, die als einstellbares Verbindunpsteil im Ausleger 36 und in einem Drehzapfen 39 der Kurbel 25 angelenkt ist. Die Achse des Drehzapfens 39 fällt mit der Achse des Gelenkes 19 zusammen. Bei der ίο zweiten Ausführungsform nach Fig. 4 ist als Verstelleinrichtung 37 ein Druckzylinder 40 verwendet, der mit seinem einen Ende gelenkig am Ausleger 36 angeschlossen ist und dessen Kolbenstange 41 gelenkig mit der Kurbel 25 verbunden ist. Über diesen Druckzylinder 40 kann die Scheibe 1 über eine entsprechende Steuerung während des Bearbeitungsvorganges so geschwenkt werden, wie es die Oberfläche des zu bearbeitenden Werkstückes erfordert, eine Bewegung des Gestelies ?", in horizontaler oder vertiao kaier Richtung ist dazu IUc¹H notwendig, da ja die Mitte 13 der Bearbeitungsfläche 14 bei der Schwenkbewegung an ihrer Stelle verbleibt.The frame 15 is provided with a bracket 36, ar. which is engaged by an adjusting device 37 with which the machining body 5 is moved via the crank 25. The adjusting device 37 in the first embodiment (FIGS. 1 to 3) consists of a threaded rod 38 which is articulated as an adjustable connecting part in the arm 36 and in a pivot 39 of the crank 25. The axis of the pivot 39 coincides with the axis of the joint 19. In the second embodiment according to FIG. 4, a pressure cylinder 40 is used as adjusting device 37, one end of which is articulated to boom 36 and whose piston rod 41 is articulated to crank 25. Using this pressure cylinder 40, the disk 1 can be swiveled during the machining process via a corresponding control as required by the surface of the workpiece to be machined, a movement of the frame? ", in the horizontal or vertical direction, IUc ¹ H is necessary for this, since the center 13 of the processing surface 14 remains in its place during the pivoting movement.

Zur Einstellung auf entsprechende Werkstücke kann der Bearbeitungskörper 5 nach oben oder unten oder seitlich über einen Kreuzschlitten 9 verstellt werden, das Gestell 15 ist dazu als Schlitten 42 ausgebildet, der in vertikaler Richtung gleiten kann, dieser Schlitten sitzt auf einem weiteren Schlitten 43, der am Ständer 6 angeordnet ist und eine Horizontalbewegung zuläßt.The machining body 5 can move upwards or downwards for adjustment to corresponding workpieces or can be adjusted laterally via a compound slide 9, the frame 15 is designed as a slide 42 for this purpose, which can slide in the vertical direction, this slide sits on a further slide 43, which is on Stand 6 is arranged and allows horizontal movement.
