Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Gegenstand vorliegender Erfindung ist eine Maschine, welche bezweckt, Kugeln nicht nur blank zu schleifen oder zu poliren, sondern auch bei denselben eine genaue und runde Kugeloberfläche zu erzielen.The subject of the present invention is a machine which aims not only to balls to grind or polish bright, but also an exact and round one To achieve spherical surface.

Fig. ι der Zeichnung stellt einen senkrechten, Fig. 2 einen waagerechten Schnitt der Maschine dar.Fig. Ι of the drawing shows a vertical section, Fig. 2 shows a horizontal section of the machine represent.

Wie aus Fig. 1 hervorgeht, besteht die Schleif- oder Polirvorrichtung der Maschine aus der in der Traverse m fest angeordneten Scheibe b mit Luftöffnungen i und nach innen einspringendem schrägen Rand. Innerhalb dieser Scheibe b ist die am Rand nach aufsen abgeschrägte Reibscheibe c auf einer Buchse a gelagert, und zwar so, dafs sie mittelst Feder g (s. Pfeilrichtung) stets gegen die Innenfläche der festen Scheibe b geprefst wird. Durch die Anordnung beider Scheiben b und c bildet sich eine Nuth oder Rille zur Aufnahme der Kugeln k, welche durch das konische Unterfangen und gleichzeitige Anpressen der Scheibe c an die Kugeln k in der Drehrichtung der Scheibe c vermöge der Reibung sich bewegen.As can be seen from Fig. 1, the grinding or polishing device of the machine consists of the disc b fixedly arranged in the cross member m with air openings i and an inwardly receding inclined edge. Inside this disk b , the friction disk c , which is bevelled outward at the edge , is mounted on a bushing a, in such a way that it is always pressed against the inner surface of the fixed disk b by means of spring g (see direction of arrow). The arrangement of the two disks b and c forms a groove or groove for receiving the balls k, which move in the direction of rotation of the disk c by virtue of friction due to the conical undertaking and simultaneous pressing of the disk c against the balls k.

Unterhalb der Kugeln k ist die Arbeitsoder Schmirgelscheibe d auf einer verstellbaren Welle e gelagert, und zwar so, dafs dieselbe gegen die Kugeln k zwecks Schleifens oder Polirens gehoben und vermittelst der Gegenmuttern f eingestellt wird. Ferner bewegt sich die Schleifscheibe d entgegengesetzt zur Reibscheibe c (s. Pfeilrichtung Fig. 1).Below the balls k the work or emery disk d is mounted on an adjustable shaft e , in such a way that it is lifted against the balls k for the purpose of grinding or polishing and is adjusted by means of the counter nuts f. Furthermore, the grinding wheel d moves in the opposite direction to the friction disk c (see arrow direction in FIG. 1).

Die verstellbare Welle kann in der Buchse a concentrisch oder (s. Fig. 2) excentrisch gelagert werden, um den Kugeln auf der Schleifscheibe d eine gröfsere Arbeitsfläche zu geben.The adjustable shaft in the socket a concentric or (s. Fig. 2) are mounted eccentrically to the balls on the grinding wheel working surface gröfsere a d to give.

Wie nun aus obiger Anordnung der Schleifoder Polirvorrichtung zu ersehen ist, wird es auf diese Weise möglich gemacht, dafs die zu schleifenden Kugeln eine genaue und runde Oberfläche von bester Arbeit erhalten.As can now be seen from the above arrangement of the grinding or polishing device, it becomes in this way made possible that the balls to be ground are accurate and round Surface obtained from the best work.

Die Kugelschleif- und Polirmaschine wird sowohl in jeder Gröfse und Form, als auch mit verschiedenen Lagen der Antriebachse, wie senkrecht, waagerecht oder umgekehrt mit Arbeitsscheibe oben hergestellt.The ball grinding and polishing machine is available in every size and shape, as well as with different positions of the drive axis, such as vertical, horizontal or vice versa with Working disk made above.

Claims (1)

Pate nt-Anspruch:Sponsorship claim: Kugelschleifmaschine, dadurch gekennzeichnet, dafs eine mittelst einer unter achsialem Feder- (g) oder Gewichtsdruck stehenden umlaufenden Nabe (α) durch Reibung angetriebene kegelabschnittförmige Scheibe^ die zu schleifenden Kugeln in dem innen hohlkegelförmigen Rande einer festen Scheibe (b) gegenüber einer umlaufenden Schmirgelscheibe (d) derart führt, dafs die dabei gebildete schwalbenschwanzförmige Führungsnuth sich selbstthälig den infolge der fortschreitenden Bearbeitung kleiner werdenden Kugeln stetig anpafst.Ball grinding machine, characterized in that a conical segment-shaped disc, which is driven by friction by means of a rotating hub (α) which is under axial spring (g) or weight pressure, holds the balls to be ground in the inner hollow-conical edge of a fixed disc (b) opposite a rotating emery disc ( d) leads in such a way that the dovetail-shaped guide groove formed in the process continuously adapts itself to the balls, which become smaller as a result of the progressive machining.
