Description
Bei den in Gebrauch befindlichen spitzenlosen Rundschleifmaschinen hatte die Führungsscheibe eine Drehbewegung, die an der Schleif stelle nach oben gerichtet war, während die Drehrichtung der Schleifscheibe nach unten gerichtet ist, um das Werkstück auf die Unterlage zu halten. Das Festhalten gelang jedoch nur unvollkommen, selbst ein Springen des Werkstückes konnte nicht ver-In the case of the centreless ones in use Cylindrical grinding machines, the guide disk had a rotary motion that was directed upwards at the grinding point the direction of rotation of the grinding wheel is downwards in order to hold the workpiece on the base. Holding on succeeded only imperfectly, even a jumping of the workpiece could not
• ° hindert werden. Diese Nachteile werden durch die Erfindung beseitigt, die darin besteht, daß die Scheibe jeweils an der dem Werkstück am nächsüen liegenden Stelle ihres Umfanges elektromagnetisch ist und an dieser Stelle eine nach unten gerichtete Drehbewegung ausführt.• ° be prevented. These disadvantages are eliminated by the invention, which consists in that the disk is in each case at the point of its next to the workpiece Circumference is electromagnetic and at this point a downward rotary movement executes.
■In Abb. ι ist eine Transportscheibe dargestellt, .deren ganzer Umfang aus Elektromagneten besteht, und in Abb. 2 eine solche, bei der in der Transportscheibe ein feststehender Magnet angeordnet ist, der durch die sich drehende Scheibe hindurch wirkt. Die Transportscheibe b (Abb. 1) wird durch mehrere Elektromagneten c gebildet, die auf den ganzen Umfang der Scheibe verteilt sind. Aber nur ein Magnetsystem, welches dem Arbeitsstück d am nächsten ist, ist unter Strom gesetzt, während alle anderen stromlos sind, also nicht magnetisch.■ In Fig. Ι a transport disk is shown, whose entire circumference consists of electromagnets, and in Fig. 2 one in which a stationary magnet is arranged in the transport disk, which acts through the rotating disk. The transport disk b (Fig. 1) is formed by several electromagnets c , which are distributed over the entire circumference of the disk. But only one magnet system, which is closest to the workpiece d, is energized, while all the others are de-energized, i.e. not magnetic.
Durch den Magnetismus der sich in Pfeilrichtung drehenden Scheibe wird das Werkstücke unbedingt ruhig auf der Unterlagen an .der Schleifscheibe a, die sich an der Schleifstelle von oben nach unten.dreht, vorbeigeführt, und somit ist ein genaues Schleifen gesichert.Due to the magnetism of the disc rotating in the direction of the arrow, the work piece is absolutely quietly guided past the base of the grinding wheel a, which rotates from top to bottom at the grinding point, and precise grinding is thus ensured.
Abb. 2 zeigt eine Transportscheibe mit denselben Wirkungen wie Abb. 1, jedoch steht hier der Elektromagnet / innerhalb der Scheibe fest, und zwar in derselben Höhe wie das Werkstück g. Die magnetische Kraft wirkt hier durch die Scheibe auf das Werkstück und verursacht dieselbe Wirkung wie bei der Anordnung nach Abb. 1.Fig. 2 shows a transport disk with the same effects as Fig. 1, but here the electromagnet / is fixed within the disk, and at the same height as the workpiece g. The magnetic force acts here through the disk on the workpiece and causes the same effect as with the arrangement according to Fig. 1.
