Description
Die Erfindung betrifft eine Vorrichtung, mittels welcher diejenigen Flächen der Kolbenzapfen von Kraftmaschinen mit umlaufenden Kolben (vgl. die deutsche Patentschrift 40191) der Rundung des Zylinders entsprechend bearbeitet werden, welche an der Durchtrittsstelle die innere Zylinderfläche zu einer geschlossenen Fläche ergänzen. Das wesentliche Merkmal der Einrichtung besteht darin, daß die Kolbenzapfen sämtlicher in einem Rundzylinder zur Verwendung gelangenden Kolben in einem sich drehenden zylindrischen Futter befestigt sind und gleichzeitig in der Lage durch ein Werkzeug bearbeitet werden, die sie im Betriebe einnehmen. Das Werkzeug bearbeitet die genannten Flächen der Kolbenzapfen der Rundung des Rundzylinders entsprechend. Als Bearbeitungswerkzeug kann ein Fräser von einer dem lichten Durchmesser des Rundzylinders der zugehörigen Maschine entsprechenden Größe verwendet werden. · Das die Kolbenzapfen während der Bearbeitung aufnehmende zylindrische Futter dient dem die feststehende Fräsvorrichtung tragenden Halter als Führung. The invention relates to a device by means of which those surfaces of the piston pin of engines with rotating pistons (cf. German patent specification 40191) corresponding to the rounding of the cylinder be processed, which at the point of passage to the inner cylinder surface complement a closed area. The main feature of the facility is made in that the piston pins are all used in a round cylinder Pistons are fixed in a rotating cylindrical chuck and at the same time able to be machined by a tool that they occupy in the factory. That The tool processes the named surfaces of the piston pin of the rounding of the round cylinder corresponding. As a machining tool, a milling cutter with one of the clear diameter of the round cylinder can be used corresponding machine size can be used. · That the piston pin Cylindrical chucks that receive during machining serve the fixed ones Milling device carrying holder as a guide.
Auf den Zeichnungen ■ zeigt Fig. 1 die Vorrichtung im Querschnitt und Fig. 2 in Seitenansicht zum Teil im Längsschnitt.In the drawings, FIG. 1 shows the Device in cross section and FIG. 2 in side view, partly in longitudinal section.
Die Kolbenzapfen 1,1,1, die z. B. für eine Kraftmaschine mit drei umlaufenden Kolben erforderlich sind und deren die Zylinderwandung an der Durchtrittsstelle ergänzende Flächen 2, 2, 2 bearbeitet werden sollen, sind in einem zylindrischen Futter 3 von der aus Fig. ι ersichtlichen Form mittels einer Scheibe 4 eingespannt, die in irgendeiner geeigneten Weise an dem Futter 3 befestigt ist. Das Futter 3 sitzt auf einer Welle S, die in langsame Umdrehung versetzt wird, und ein ringförmiger Flansch 6 desselben dient zugleich einem gegen Drehung gesicherten Halter 7 als Führung, in welchem die mittels der Riemenscheibe 10 angetriebene Welle 8 der Fräsvorrichtung gelagert ist.The piston pin 1,1,1, the z. B. for a Engine with three rotating pistons are required and the cylinder wall Supplementary surfaces 2, 2, 2 are to be processed at the point of passage in a cylindrical chuck 3 of the form shown in Fig. ι by means of a Disc 4 clamped, which is attached to the chuck 3 in any suitable manner. The chuck 3 sits on a shaft S, which is set in slow rotation, and a annular flange 6 of the same also serves as a holder secured against rotation 7 as a guide, in which the shaft 8 driven by the pulley 10 of the Milling device is stored.
Die Fräsvorrichtung besteht aus einem Fräser 9, dessen Größe dem lichten Durchmesser des Rundzylinders der Kraftmaschine entspricht, so daß die Flächen 2 der Kolbenzapfen eine der Rundung der Zylinderwandung entsprechende Gestaltung erhalten.The milling device consists of a milling cutter 9, the size of which corresponds to the inside diameter of the round cylinder of the engine corresponds, so that the surfaces 2 of the piston pin receive a design corresponding to the rounding of the cylinder wall.
Die ganze Vorrichtung kann in einer Drehbank zwischen der Spindel und dem Reitstock eingespannt werden.The whole device can be placed in a lathe between the spindle and the tailstock be clamped.
