Description

Spitzenlose Schleifmaschine zum Rundschleifen von Werkstücken Die Erfindung betrifft eine spitzenlose Schleifmaschine zum Rundschleifen von Werkstücken im Durchgangsverfahren mit einer Schleifscheibe und einer V-förmig ausgebildeten Werkstückauflage sowie einer Antriebsvorrichtung zum Drehen der Werkstücke, die so angeordnet ist, daß die Werkstücke, schon bevor sie die Schleifscheibe berühren, in Umdrehung versetzt werden.Centerless grinding machine for cylindrical grinding of workpieces The The invention relates to a centerless grinding machine for cylindrical grinding of workpieces in a straight through process with a grinding wheel and a V-shaped one Workpiece support and a drive device for rotating the workpieces that is arranged in such a way that the workpieces, even before they touch the grinding wheel, be set in rotation.

Bei Maschinen dieser Art mittet sich das Werkstück nicht von selbst ein, da die Führungsrinne neben der Umfangsfläche der Schleifscheibe liegt. Es muß daher eine dem Werkstückdurchmesser entsprechende Höheneinstellung vorgenommen werden.With machines of this type, the workpiece does not center itself because the guide groove is next to the peripheral surface of the grinding wheel. It must therefore a height adjustment corresponding to the workpiece diameter must be made.

Erfindungsgemäß wird vorgeschlagen, die V-förmig ausgebildete Werkstückauflage so anzuordnen, daß die Halbierungsebene der V-förmig ausgebildeten Werkstückauflage in einer axialen Schnittebene der Schleifscheibe liegt. Dadurch läßt sich auf einfache Weise das genaue Maß der Zustellung unabhängig vom Werkstückdurchmesser einstellen, weil die Berührungslinie der Schleifscheibe mit dem Werkstück immer in der gleichen Ebene liegt.According to the invention it is proposed that the V-shaped workpiece support to be arranged so that the bisection plane of the V-shaped workpiece support lies in an axial section plane of the grinding wheel. This makes it easy to Way, set the exact amount of infeed regardless of the workpiece diameter, because the line of contact between the grinding wheel and the workpiece is always the same Level lies.

In den Zeichnungen ist ein Ausführungsbeispiel der Erfindung dargestellt. Das Werkstück 1 liegt in einer V-förmig ausgebildeten Werkstückauflage 2, deren Halbierungsebene zu einer axialen Schnittebene der Schleifscheibe 3 angeordnet ist. Die Drehbewegung des Werkstückes wird durch einen Ring 4, der vor der Schleifscheibe 3 liegt, durch Reibung auf das Werkstück 1 übertragen. Das Werkstück 1 wird nun an der Schleifscheibe vorbeigeschoben. Dabei tritt eine Änderung der Antriebsverhältnisse ein, insofern, als jetzt das Werkstück von der Schleifscheibe angetrieben wird und die Regeleinrichtung bremsend wirkt. Eine weitere Bremsung wird durch die Reibung im Führungsprisma bewirkt. Für Fälle, bei denen das nicht ausreicht, können noch zusätzliche Bremseinrichtungen 5, 6 angeordnet werden.In the drawings, an embodiment of the invention is shown. The workpiece 1 lies in a V-shaped workpiece support 2, the Halving plane is arranged to an axial section plane of the grinding wheel 3. The rotation of the workpiece is controlled by a ring 4 in front of the grinding wheel 3 is transferred to the workpiece 1 by friction. The workpiece 1 is now pushed past the grinding wheel. There is a change in the drive ratios one, insofar as the workpiece is now driven by the grinding wheel and the control device has a braking effect. Another braking effect is caused by friction causes in the guide prism. For cases where this is not enough, you can still additional braking devices 5, 6 are arranged.
