Description
Die vorliegende Erfindung betrifft einen ausschwingbaren Werktisch an Werkzeugmaschinen, insbesondere an Schleifmaschinen.The present invention relates to a swingable Workbench on machine tools, in particular on grinding machines.
Sie beruht auf der Tatsache, daß die modernen Werkzeuge für die Metallbearbeitung, insbesondere diejenigen, die mit einer Auflage von Wolframkarbid versehen sind, unter bestimmten Winkeln der Schleifscheibe zugeführt werden müssen und eine abwechselnde Verschiebebewegung senkrecht zuIt is based on the fact that modern tools for metalworking, in particular those that are provided with a layer of tungsten carbide, at certain angles the grinding wheel must be fed and an alternating displacement movement perpendicular to it
ίο dem Weg der Körner der Schleifscheibe ausführen müssen.ίο follow the path of the grains of the grinding wheel have to.
Die Erfindung bezweckt nun, diese Bewegung des das zu schleifende Werkzeug tragenden Tisches mit geringster Anstrengung des Arbeiters auszuführen, eine Bewegung, welche gleichzeitig den Zweck hat, die Erwärmung zu verteilen und die Abnutzung der Schleifscheibe über ihre ganze Fläche zu erreichen ohne eine mechanische Steuerung.The invention now aims at this movement of the table carrying the tool to be ground with to carry out the least effort on the part of the worker, a movement which at the same time has the purpose of to distribute the heating and to achieve the wear and tear of the grinding wheel over its entire surface without a mechanical control.
Zu diesem Zweck besteht die Erfindung im wesentlichen darin, daß der Tisch gegenüber dem Sockel abgestützt ist durch zwei starre Schwingen und durch Federn, die am Tisch und am Sockel befestigt sind, gegen den Sockel gezogen wird. Die Federn sind dabei in teilweise längs verstellbaren Schlaufen eingehängt und dienen auch als Schwingen. Sie sind gleichzeitig in der Längs- und in der Querrichtung schräg gestellt.For this purpose, the invention consists essentially in that the table opposite the The base is supported by two rigid rockers and springs on the table and on the base are attached, is pulled against the base. The springs are partially adjustable lengthways Loops are attached and also serve as a swing. They are at the same time in the longitudinal and in the Tilted transversely.
Andererseits ist die Bewegung der festen Schwingen, welche gewöhnlich in Lagerausschnitten des Tisches und des Sockels geführt werden, in der Querrichtung begrenzt durch am Tisch und am Sockel befestigte Anschlagplatten, die über Nasen der Schwingen greifen.On the other hand, the movement of the fixed rocker, which is usually carried out in the bearing sections of the The table and the base are guided in the transverse direction by the table and the Stop plates attached to the base, which grip over the lugs of the rocker arms.
Die Zeichnung zeigt ein Ausführungsbeispiel der Erfindung. Fig. 1 ist eine Vorderansicht und Fig. 2 ein Querschnitt.The drawing shows an embodiment of the invention. FIG. 1 is a front view and FIG. 2 a cross section.
Der Werktisch einer Werkzeugmaschine, z. B. einer Schleifmaschine, ist mit 1 bezeichnet und der Sockel, auf dem er einerseits mit Hilfe der beiden festen Schwingen 3 und andererseits mit Hilfe der Federn 7 ruht, mit 2.The work table of a machine tool, e.g. B. a grinding machine is denoted by 1 and the Base on which he is on the one hand with the help of the two fixed rockers 3 and on the other hand with the help of Springs 7 rests, with 2.
Die Schwingen 3 sind in V-förmigen Lagerausschnitten des Tisches und des Sockels geführt, und ihre Querbewegung wird begrenzt durch die Anschlagplatten 4, die am Tisch 1 und am Sockel 2 befestigt sind, beispielsweise durch die Schrauben 6. Diese Platten 4 sind außerdem über Vorsprünge 5 abgebogen, die oben und unten an den Schwingen 3 sich befinden und diese festhalten gegen seitliche Verschiebung.The rockers 3 are guided in V-shaped bearing cutouts of the table and the base, and their transverse movement is limited by the stop plates 4 on the table 1 and on the base 2 are fastened, for example by the screws 6. These plates 4 are also over projections 5 bent, the top and bottom of the rocker 3 are and hold them against the side Shift.
Die Federn 7 sind unten durch ösen 8 mit dem Sockel 2 verbunden und oben mit dem Tisch 1 durch einstellbare Schlaufen 9. So bilden diese ösen 8 und Schlaufen 9 gleichsam Schneiden, auf denen die Haken der Federn schwingen.The springs 7 are connected to the base 2 by eyelets 8 at the bottom and to the table 1 at the top adjustable loops 9. So form these eyelets 8 and loops 9 as it were cutting on which the Swing hooks of springs.
Wie aus der Zeichnung hervorgeht, sind die Federn 7 gleichzeitig in der Längs- und in der Querebene schräg gerichtet. As can be seen from the drawing, the springs 7 are simultaneously directed obliquely in the longitudinal and in the transverse plane.
Die Schräglage in der Längsebene bewirkt eine Gleichgewichtslage des Tisches in der Mittelstellung, wie aus Fig. 1 hervorgeht, und gestattet auch seine Verschiebung nach links und nach rechts bei nur geringer Anstrengung, etwa bei Betätigung mittels eines Handgriffes 10. Der Tisch ist somit bestrebt, immer wieder in seine Gleichgewichtslage zurückzukehren; er schwingt wie ein Pendel, und die Unterhaltung dieser Schwingungen erfordert nur eine vollständig vernachlässigbare Anstrengung seitens des Arbeiters.The inclined position in the longitudinal plane results in an equilibrium position of the table in the middle position, as can be seen from Fig. 1, and also allows its shift to the left and to the right at only little effort, for example when actuated by means of a handle 10. The table thus strives to to return to his equilibrium again and again; he swings like a pendulum, and the conversation these vibrations require only a completely negligible effort on the part of the worker.
Die Schräglage der Federn 7 in der Querrichtung bezweckt, die Schwingen 3 stets gegen dieselben Anschlagplatten 4 anzulegen, um ständig ein Spiel zu verhindern.The oblique position of the springs 7 in the transverse direction is intended to keep the rockers 3 always against the same Apply stop plates 4 to constantly prevent play.
