Description

Bei der Verwendung von Werkzeugen für die Bearbeitung von Schleifflächen od. dgl. an Ver-,brennungstmotoren od. d'gl. liegen diese Flüchen oft so ungünstig; da:ß man nur mit besonders geformten Haltern, wie gebogenen oder gekröpften Auslegern,-arbeiten kann.When using tools for machining grinding surfaces or the like on internal combustion engines or the like. are these curses often so unfavorable; because: ß you can only work with specially shaped holders, such as curved or cranked arms can.

Die Erfindung bezieht sich auf ein solches Werk- . zeug, das- im besonderen zur Bearbeihung von Ventilsitzflächen oder ähnlichen Schleifflächen dienen soll. Der Antrieb solcher mit höchster Drehzahl laufender Werkzeuge war bisher wegen der vielen Lagerstellen und Getriebe umständlich, und die einzelnen Teile waren .den auftretenden Erschütterungen allzu sehr ausgesebzt, .so d@aß sie bald unbrauchbar würden.The invention relates to such a work. stuff that- in particular to be used for machining valve seat surfaces or similar grinding surfaces. The drive of such tools running at the highest speed was previously because of the many bearings and gears cumbersome, and the individual parts were .den too much exposed to vibrations, so they soon became unusable would.

Die Erfindung betrifft nun ein solches Werkzeug mit gebogenem Ausleger, bei dem, ein neuerdings entstandener Werkzeugantrieb Verwendung findet., der die erforderliche axiale Federung möglichst nahe an das Werkzeug selbst legt.The invention relates to such a tool with a curved arm, in which a recently developed tool drive is used., which the required axial suspension as close as possible to the tool itself.

Die bisher für gebogene Ausileger bekanntgewordenen Antriebseinrichtungen, etwa mit loser Kupplung und Kegelradgetrieben, sind ebenfalls noch zu umständlich, kogfispielig und nicht erschütterungsfrei.The drive devices that have so far become known for curved outriggers, with loose coupling and bevel gears, for example, are still too cumbersome, Easy to use and not free from vibrations.

Der Werkzewgantr rieb nach der Erfindung besteht aus einer in einem gebogenen Auele@ger gelagerten biegsamen Welle, die zwischen dem federnden Kupplungsglied für den Werkzeughalter und dem Wellenantrieb eigeschaltet ist. -Durch- die Verwendung einer bekannten biegsamen Welle werden alle bisher angeordneten Zwischenteile ivberflifis,sig. Hierbei ist es möglich, das Kupplungsglied an seinem Schaft ortsfest in Kugellagern zu lagern, ahne da.ß Erschütterungen Einflug gewinnen können. In :der Zeichnung ist der neue Antrieb im Schnitt dargestellt.The Werkzewgantr rubbed according to the invention consists of one in one curved Auele @ ger mounted flexible shaft between the resilient coupling member is switched on for the tool holder and the shaft drive. -By- the use a known flexible shaft are all previously arranged intermediate parts ivberflifis, sig. Here it is possible to have the coupling member stationary on its shaft in ball bearings to camp, foresee that tremors can gain entry. In the drawing the new drive is shown in section.

In einem gebogenem. hohlen Ausleger i ist eine biegsrame Welle Z innerhalb eines (Metall-) Sehlauches 3 angeordnet und an den Enden mit dem Antriebsteil, der Motorwelle q. und dem Schaft 5 des: Abtriebsteiles, etwa eines Kupplungsgliedes 6, fest verbunden. Dieser Schaft 5 ist ortsfest in den Kugellagern 7 am Ende des Ausilegers i gelagert. Das Kupplungsglied 6 hat eine in Richtung der Drehachse A federnd bewegliche Kugel 8; die auf der Platte 9 des zweiten Kupplungsgliedes io aufsitzt. Das Glied ro gehört zum Werkzeughalter (Schleifsteinhalter). Zur Dichtung derLager 7 sind Dichtungsscheiben ii und 12 angebracht. Die biegsiame Welle z liegt freu innerhalb des Auslegers und kann sich zwischen den beiden Befestigungspunkten an den Lagerstellern frei bewegen. Die Schleifstöße werden durch die gefederte Kugel 8 und höchstenfall,sr noch- durch die Kugellage-r 7 und die biegsame Welle a aufgefangen..In a curved one. hollow boom i is a flexible shaft Z within a (metal) Sehlauches 3 arranged and at the ends with the drive part, the Motor shaft q. and the shaft 5 of the: output part, such as a coupling member 6, firmly connected. This shaft 5 is stationary in the ball bearings 7 at the end of the Ausilegers i stored. The coupling member 6 has a direction of the axis of rotation A. resiliently movable ball 8; on the plate 9 of the second coupling member io sits on. The link ro belongs to the tool holder (grindstone holder). To poetry the bearings 7 are sealing washers ii and 12 attached. The flexible shaft z lies happy inside the boom and can move between the two attachment points move freely on the bearing plates. The grinding joints are made by the spring-loaded ball 8 and at most, sr still- caught by the ball bearing-r 7 and the flexible shaft a ..
