Description

Vorrichtung zum Prägepolieren von kreisrunden, am Gestell der Vorrichtung auf Körnerspitzen drehbar gelagerten Körpern, insbesondere von Achsschenkeln. Die Erfindung bezieht sich auf Vorrichtungen zum Prägepolieren von kreisrunden, am Gestell der Vorrichtung auf Körnerspitzen drehbar gelagerten Körpern, insbesondere von Achsschenkeln, und bezweckt, eine möglichst vollkommene Entlastung der Körnerspitzen von dem Druck der gleichfalls am Gestell angeordneten Prägerollen zu gewährleisten.Device for embossing of circular, on the frame of the device Bodies rotatably mounted on center points, in particular of steering knuckles. the The invention relates to devices for burnishing circular, on the frame of the device rotatably mounted bodies on grain tips, in particular of steering knuckles, and aims to relieve the grain tips from the pressure as completely as possible to ensure the embossing rollers also arranged on the frame.

<4uf der Zeichnung ist ein zum Polieren der Achsschenkel eines Eisenbahnradsatzes bestimmtes Ausführungsbeispiel des Erfinclungsgegenständes dargestellt, und zwar zeigt Abb. i eine teilweise im Schnitt dargestellte Stirnansicht der Poliervorrichtung und Abb.2 einen Schnitt nach Linie 2-2 der Abb. i, von links gesehen.<4 of the drawing is one for polishing the steering knuckles Railway wheelset specific embodiment of the subject matter of the invention shown, namely, Fig. i shows a partially sectioned end view of the polishing apparatus and Fig. 2 is a section along line 2-2 of Fig. i, seen from the left.

Am Gestell A der nach Art einer Drehbank mit einem (nicht dargestellten) Spindelstock und einem Reitstock A1 ausgerüsteten Poliervorrichtung ist ein mittels einer Spindel C in der Längsrichtung der Vorrichtung verschiebbarer Vorschubschlitten B angeordnet. Auf dem Schlitten B sind zwei Tragkörper D und E senkrecht zur Bewegungsrichtung des Schlittens B nach einander entgegengesetzten Seiten verschiebbar. Zur Verschiebung der Tragkörper D und E dient eine mit rechts-und linksgängigem Gewinde versehene Schraubenspindel F, die in dem Schlitten B drehbar, aber unverschiebbar gelagert ist und in Führungsmuttern d' und e' eingreift, die an den Tragkörpern befestigt sind. In dem einen der beiden Tragkörper, D, ist eine Prägerolle G gelagert, deren Drehachse in gleicher Höhe mit den Körnerspitzen a= liegt und der Verschiebungsrichtung des Schlittens B parallel ist. In dem anderen Tragkörper, E, ist mittels eines Zapfens e2, dessen Achse ebenfalls in gleicher Höhe mit den Körnerspitzen a= liegt und der Verschiebungsrichtung des Schlittens B parallel ist, ein Halter H für zwei weitere Prägerollen, J und K, drehbar gelagert,. deren Achsen der Drehachse der Rolle G parallel sind.On the frame A of the polishing device equipped in the manner of a lathe with a headstock (not shown) and a tailstock A1, a feed slide B which can be displaced in the longitudinal direction of the device by means of a spindle C is arranged. On the slide B , two support bodies D and E can be displaced perpendicular to the direction of movement of the slide B to opposite sides. To move the support bodies D and E, a screw spindle F provided with a right-hand and left-hand thread is used, which is rotatably but immovably mounted in the carriage B and engages in guide nuts d 'and e' which are attached to the support bodies. In one of the two support bodies, D, an embossing roller G is mounted, the axis of rotation of which is at the same height as the grain tips a = and the direction of displacement of the slide B is parallel. In the other support body, E, a holder H for two further embossing rollers, J and K, is rotatably mounted by means of a pin e2, the axis of which is also at the same height as the punch tips a = and the direction of displacement of the carriage B is parallel. whose axes are parallel to the axis of rotation of the roller G.

Der Radsatz, dessen Achsschenkel zu polieren sind, wird, rivie aus Abb. 2 ersichtlich ist, zwischen die Körnerspitzen ader Poliervorrichtung eingespannt und von dein (nicht dargestellten) Spindelstock aus in Umdrehung versetzt. Nachdem mittels der Schraubenspindel F die an den Tragkörpern D und E angeordneten Prägerollen G, J und K gegen die zu polierende Lauffläche eines Achsschenkels angepreßt sind, werden die Druckrollen von dem umlaufenden Achsschenkel in Z'_ndrehung versetzt und durch den gleichzeitig mittels der Spindel C in der Längsrichtung des Achsschenkels verschobenen Schlitten B an der zu polierenden Lauffläche des Achsschenkels entlanggeführt.The wheel set, the steering knuckle of which is to be polished, is rivie out Fig. 2 can be seen, clamped between the grain tips of the polishing device and rotated from your headstock (not shown). After this the embossing rollers arranged on the supporting bodies D and E by means of the screw spindle F G, J and K are pressed against the running surface of a steering knuckle to be polished, the pressure rollers are set in Z'_turn by the rotating stub axle and by simultaneously by means of the spindle C in the longitudinal direction of the steering knuckle moved carriage B along the running surface of the steering knuckle to be polished.

Die beschriebene Vorrichtung hat zunächst den Vorteil, daß nicht nur an der zviindrischen Mantelfläche des Achsschenkels, sondern ohne weiteres auch in den Hohlkehlen die gewünschte Politur erzielt werden kann. Ferner besteht infolge der Lagerung der Rollen J und K in dein drehbaren Halter H der weitere Vorteil, daß mit Sicherheit darauf gerechnet werden kann, daß stets alle drei Rollen G, J und k gleichzeitig an dem Achsschenkel anliegen. Insbesondere ist dies auch dann der Fall, wenn z. B. infolge von Verschleiß der Schlittenführung eine Veränderung in der gegenseitigen Höhenlage der Rollen und der Körnerspitzen eintritt. Durch die gleichzeitige Anlage der Prägerollen wird das Auftreten eines einseitigen Druckes auf dem Achsschenkel vermieden und somit eine möglichst vollkommene Entlastung der Körnerspitzen erreicht.The device described initially has the advantage that not only on the cylindrical lateral surface of the steering knuckle, but also without further ado the desired polish can be achieved in the fillets. Furthermore, as a result the storage of rollers J and K in your rotatable holder H is another advantage, that it can be counted on with certainty that all three roles G, J and k at the same time rest on the steering knuckle. In particular, this is also the case the case when z. B. due to wear of the slide guide a change occurs in the mutual height of the rollers and the grain tips. By the simultaneous application of the embossing rollers will result in one-sided printing on the steering knuckle avoided and thus a complete relief of the Grain peaks reached.
