Description
Vorrichtung zum Schleifen von Kurbelzapfen mittels eines kreisenden Innenschleifrings Schleifvorrichtungen für Kurbelzapfen, z. B. von Lokomotivradsätzen, mittels eines kreisenden Innenschleifrings sind mehrfach bekannt geworden. Diese bekannten Einrichtungen weisen den Übelstand auf, daß ihre Befestigung und Zentrierung an denn zu schleifenden Werkstück umständlich ist und zuviel Zeit erfordert.Device for grinding crank pins by means of a rotating Inner slip ring Grinding devices for crank pins, e.g. B. of locomotive wheel sets, by means of a rotating inner slip ring have become known several times. These known devices have the disadvantage that their attachment and centering because the workpiece to be ground is cumbersome and takes too much time.
Dieser übelstand wird.durch die Erfindung dadurch vermieden, daß in den Werkzieugschlittenein Elektromagnet eingebaut ist, der das Festhalten und schnelle Zentrnerren bewirkt.This disadvantage is avoided by the invention in that in The tool slide is built into an electromagnet, which holds and fast Central causes.
In den Abb. r und 2 ist eine beispielsweise Ausführungsform der Erfindung dargestellt. Der Schättenhaltera enthält einen Elektromagneten mit innenliegender Magnetwicklung und den axial verschiebbaren Körner b. Dieser Schlittenhaltera besitzt zu seiner Sicherung gegen Verdrehen an seinem oberen Ende einen Arm c, welcher um den zu schleifenden Zapfen greift. Das erforderliche Spiel dies Armauges zum überschieben über den Zapfen wird durch die Klemmschrauben d ausgeglichen. Mit dem Schlittenhalter verbunden ist die hohle Schlittenachse e, auf welcher die Schlittenführung f drehbar gelagert ist. Die Feststellung der Schlittenführung auf der Schlittenachse wird durch die Mutter g bewirkt. Auf der Schlittenachse j bewegt sich geradlinig der Schlitten h, der in einem oberen Lager das Planetengetriebe m mit dem Innenschleifringl und den S:pindelantrieb z trägt. Die radiale Beistellung des Schleifrings l erfolgt in bekannter Weise durch das Planetengetriebe und der - Arheitsvorschub durch die Spindel k.In Figs. R and 2 is an exemplary embodiment of the invention shown. The shell holder contains an electromagnet with an internal Magnet winding and the axially displaceable center b. This slide holder has to secure it against rotation at its upper end an arm c, which around grips the pin to be ground. The required play of this Armauges to slide over over the pin is balanced by the clamping screws d. With the slide holder connected is the hollow slide axis e, on which the slide guide f is rotatable is stored. The determination of the slide guide on the slide axis is caused by the mother g. The moves in a straight line on the slide axis j Slide h, the planetary gear m with the inner slip ring in an upper bearing and the S: spindle drive z carries. The radial provision of the slip ring l takes place in a known manner by the planetary gear and the - Arheitsvorschub by the Spindle k.
Wirkungisweis e Nach Zentrierung des Schlittenhalters a mittels des Dorns b wird der Elektromagnet eingeschaltet und der Arm c an dem zu schleifenden Zapfen befestigt. Nachdem der Schlittenhalter so befestigt ist, wird durch Verdrehung der Schlittenachse f auf der Achsee der Kurbelwinkel eingerichtet und durch die Mutter g festgestellt, Hierauf richtet man den Schleifhub entsprechend dem Zapfendurchmesser ein, setzt das Schneckeggetriiebe i für die Planetspindel m und die Schleifringspindel in Betrieb und betätigt den Arheitsvorscbub (Schlitten h) durch Drehen der Spindel h.How it works After centering the slide holder a by means of the Mandrel b the electromagnet is switched on and the arm c on the to be ground Fastened tenons. After the slide holder is attached in this way, it is twisted the slide axis f set up on the Achsee of the crank angle and through the Nut g determined, then adjust the grinding stroke according to the journal diameter a, sets the worm gear i for the planetary spindle m and the slip ring spindle in operation and actuates the Arheitsvorscbub (slide h) by turning the spindle H.
Die Befestigung der Schleifvorrichtung mittels des Elektromagneten kann natürlich auch an den Schenkelflächen des Kurbielarmes erfolgen.The fastening of the grinding device by means of the electromagnet can of course also be done on the leg surfaces of the crank arm.
