Zentrier- und Niveliereinrxchtung für rotationssymetrischeCentering and leveling device for rotationally symmetrical
Werkstücke.Work pieces.
Bei der Prüfung und Bearbeitung von rotationssymetrxschen Werkstücken ist es oft erforderlich das Werkstück bezüglich einer Meß- oder Bearbeitungsebene zu zentrieren und/oder die Werkstückachse in die Senkrechte zu nivelieren.When testing and processing rotationally symmetrical workpieces, it is often necessary to relate the workpiece to center a measuring or machining plane and / or to level the workpiece axis in the vertical.
Hierzu werden meistens rotierende Meßtische verwendet,die mittels handbedienter Kreuzschlitten gegenüber dem Rotationsmittelpunkt in 2 Achsen verschoben werden können und deren Neigung ebenfalls in zwei Achsen über eine Kugelwippe einstellbar ist.Diese Einstellungen sind sehr zeitaufwendig und erfordern mehrere Meß- und Einstellvorgänge,da sich die einzelnen Bewegungen gegenseitig beeinflussen.Rotating measuring tables are mostly used for this purpose can be moved in 2 axes with respect to the center of rotation by means of hand-operated compound slides and their Inclination can also be adjusted in two axes via a ball rocker. These settings are very time-consuming and require several measuring and setting processes, since the individual Movements affect each other.
Vorstehende Nachteile werden erfindungsgemäß mittels einer automatischen Zentrier- und Niveliereinrxchtung für rotationssymetrische Werkstücke,die auf einem justierbaren Drehtisch vermessen oder bearbeitet werden sollen dadurch vermieden,daß ein oder mehrere Stellmotore (Ml1M2) bei entsprechender Drehstellung des Meßtisches (ME) automatisch an die jeweilgen Stellglieder (S) angekoppelt werden.Hierbei rasten die Antriebsachsen (A1,A2) der Motore (Ml,M2) durch Vorschub mechanisch in die Aufnehmer der jeweiligen Stellglieder (S) ein,oder die Ankopplung erfolgt über Elektromagnete.The above disadvantages are avoided according to the invention by means of an automatic centering and leveling device for rotationally symmetrical workpieces that are to be measured or processed on an adjustable turntable by automatically connecting one or more servomotors (Ml 1 M2) to the respective Actuators (S) are coupled. Here, the drive axes (A1, A2) of the motors (Ml, M2) engage mechanically in the transducers of the respective actuators (S), or they are coupled via electromagnets.
Es ist bei derartigen Prüfungen üblich,die Mitt.e.lpunktsabweichung des Prüflings von der Meßtischachse über Wegmeßnehmer während einer oder mehrerer Umdrehungen des Meßtisches zu registrieren und einem Rechner zur Auswertung zu übermitteln. Dieser ist mit diesen Daten in der Lage,den Versatz in x- und y-Richtung zuerrechnen und entsprechende Steuersignale für die motorische Verstellung zu erzeugen.Mit den Signalen von zwei oder mehr in unterschiedlicher Höhe angeordneter Wegmeßnehmer kann mittels des Rechners auch dieIt is common in such tests to use the center point deviation of the test specimen from the measuring table axis via displacement transducers during one or more revolutions of the measuring table to register and to transmit to a computer for evaluation. With this data, the operator is able to determine the offset calculate in x and y directions and generate corresponding control signals for the motorized adjustment Signals from two or more transducers arranged at different heights can also use the computer

Schräglage dos Prüflings ermittelt und die notwendige Korrektur der Meßtischneigung errechnet werden.Mit diesen Daten können somit Steuersignale für die Verstellung der K\jgelwippe (K) erzeugt werden.Inclination of the test item determined and the necessary correction the measuring table inclination can be calculated using this data control signals for adjusting the rocker switch (K) can thus be generated.
Nach Positionierung des Meßtisches derart,daß z.B. die Stellglieder (S) in x-Richtung sich gegenüber den Motoren (Ml,M2) befinden,werden die Antriebsachsen der Motore mit den Stellgliedern gekoppelt.Hierauf erfolgt die Einstellung in x-Richtung entsprechend der errechneten Werte.Anschließend erfolgt die entsprechende Einstellung in y-Richtung.After positioning the measuring table in such a way that e.g. the actuators (S) in x-direction opposite the motors (Ml, M2) are located, the drive axes of the motors with the actuators The setting is then made in the x-direction according to the calculated values, followed by the corresponding setting in the y-direction.
Um weitere Zeit einzusparen,kann natürlich mit weiteren Motoren die Einstellung gleichzeitig in beiden Achsen erfolgen.To save more time, you can of course use additional motors the setting can be made in both axes at the same time.
Die Positionierung des Meßtisches und die Auswertung der erforderlichen Stellrichtung erfolgt in bekannter Weise über Winke Ischrittgeber .The positioning of the measuring table and the evaluation of the necessary Adjustment direction takes place in a known manner via angle encoder.
Werden die Wegmeßaufnehmer (Tl,T2) übereinander in Richtung der Antriebsachsen der Motore (Ml,M2) montiert,kann während des Niveliervorgangcs eine ggf. neu auftretende Mittelpunktsverschiebung sofort erkannt und nusgeregelt worden. If the transducers (Tl, T2) one above the other in the direction the drive axles of the motors (Ml, M2) mounted, can during of the leveling process, any new center shift that may occur is recognized immediately and adjusted.
