Description

Die Erfindung bezieht sich auf eine Vorrichtung zum Richten von Ventilen für Brennkraftmaschinen mit einem Stützlineal für den Ventilschaft und gegeneinander anstellbaren, achsparallel mit dem Ventilschaft, jedoch in Achsrichtung versetzt zueinander angeordneten Richtrollen. Die Erfindung besteht darin, daß eine Gruppe der Richtrollen in an sich bekannter Weise ortsfest angeordnet ist, von denen die eine, mit einem dem Ventilsitz entsprechenden Schrägbund versehene, gegen den Ventilteller und die anderen gegen den Ventilschaft anliegen und die andere, diametral. entgegenüesetzt zu der ersten angeordnete Gruppe mit zwischen je zweien der ortsfesten Rollen anliegenden Richtrollen hydraulisch gegen den Ventilteller anstellbar ist, sowie daß ein den Ventilteller abstützendes Widerlager vorgesehen ist.The invention relates to a device for straightening valves for internal combustion engines with a support ruler for the valve stem and against each other adjustable, axially parallel to the valve stem, but offset in the axial direction aligned straightening rollers. The invention consists in that a group the straightening rollers is arranged stationary in a known manner, of which the one, provided with an inclined collar corresponding to the valve seat, against the valve head and the other against the valve stem and the other, diametrically. opposed to the first arranged group with lying between each two of the stationary rollers Straightening rollers can be adjusted hydraulically against the valve disc, as well as that a the Valve plate supporting abutment is provided.

Bekannt sind Richtmaschinen für runde Stangen mit einem Stützlineal und Richtrollen. Weiterhin sind auch Wellenrichtmaschinen mit zwei nebeneinanderliegenden Walzen und einer Druckwalze bekannt.Straightening machines for round bars with a support ruler are known and straightening rollers. There are also shaft straightening machines with two adjacent Rollers and a pressure roller known.

Demgegenüber wird beim Gegenstand der Erfinr dung der Ventilschaft und der Ventilteller gleichzeitig gerichtet, was bisher nicht bekannt war.In contrast, the subject of the invention is the valve stem and the valve disc directed at the same time, which was previously unknown.

In der Zeichnung ist eine beispielsweise Ausführungsform des Erfindungsgegenstandes dargestellt. Das Ventil i wird zum Ausrichten des Schaftes auf ein Stahllineal :2 gelegt. Gegen den Schaft liegen zwei starre Richtrollen 3 und 3' und zwei bewegliche Druckrollen q. und 6 an. Gegen den Ventilteller liegt eine Rolle 5 an, die mit einem dem Ventilsitz entsprechenden Schrägbund versehen ist. Dieser Bund bewirkt, daß der Teller nicht nur im Außendurchmesser konzentrisch zum Schaft gerichtet wird, sondern daß auch der Schlag in Richtung der Ventilachse, also die Taumelbewegung beseitigt wird.The drawing shows an example embodiment of the subject matter of the invention shown. The valve i is used to align the stem on a steel ruler: 2 placed. Two rigid straightening rollers 3 and 3 'and two movable ones lie against the shaft Pressure rollers q. and 6 on. Against the valve plate is a roller 5 with a the diagonal collar is provided corresponding to the valve seat. This covenant causes the plate is not only aligned concentrically to the shaft in the outer diameter, but that also the impact in the direction of the valve axis, i.e. the tumbling movement is eliminated.

Sämtliche Rollen drehen sich. Die Druckrollen werden gegen den Schaft angedrückt, bis dieser gegen die beiden Richtrollen 3, 3' leicht durchgedrückt ist. Alsdann wird der Anpressungsdruck der Rollen q. und 6 ganz langsam zurückgenommen. Ein den Ventilteller abstützendes Widerlager 7 verhindert ein Ausweichen des Ventils in dieser Richtung.All roles spin. The pressure rollers are against the shaft pressed until it is slightly pressed against the two straightening rollers 3, 3 '. Then the contact pressure of the rollers q. and 6 withdrawn very slowly. An abutment 7 supporting the valve disk prevents the valve from evading in this direction.

PATENTANSPRUCH: Vorrichtung zum Richten von Ventilen für Brennkraftmaschinen mit einem Stützlineal für den Ventilschaft und gegeneinander anstellbaren, achsparallel mit dem Ventilschaft, jedoch in Achsrichtung versetzt zueinander angeordneten Richtrollen, dadurch gekennzeichnet, daß eine Gruppe der Richtrollen in an sich bekannter Weise ortsfest angeordnet ist, von denen eine, mit einem dem Ventilsitz entsprechenden Schrägbund versehene (5), gegen den Ventilteller und die anderen (3, 3') gegen den Ventilschaft anliegen und die andere, diametral entgegengesetzt zu der ersten angeordneten Gruppe mit zwischen je zweien der ortsfesten Rollen anliegenden Richtrollen (q., 6) hydraulisch gegen den Ventilschaft anstellbar ist, sowie daß ein den Ventilteller in Richtung der Ventilachse abstützendes Widerlager (7) vorgesehen ist. In Betracht gezogene Druckschriften: Deutsche Patentschriften Nr. 47 171, 297 70q.; schweizerische Patentschrift Nr. 29i 862; USA.-Patentschrift Nr. 1 1ö4551. PATENT CLAIM: Device for straightening valves for internal combustion engines with a support ruler for the valve stem and alignable straightening rollers axially parallel to the valve stem, but offset from one another in the axial direction, characterized in that a group of straightening rollers is fixedly arranged in a manner known per se, from one of which (5), provided with an inclined collar corresponding to the valve seat, rests against the valve plate and the other (3, 3 ') rests against the valve stem and the other, diametrically opposite to the first group, with straightening rollers resting between two of the stationary rollers (q., 6) is hydraulically adjustable against the valve stem, and that an abutment (7) supporting the valve disk in the direction of the valve axis is provided. Considered publications: German Patent Specifications No. 47 171, 297 70q .; Swiss Patent No. 29i 862; U.S. Patent No. 114551.
