Steuervorrichtung für Schleifmaschinen für mehrschneidige Werkzeugej insbesondere für MesserköpfeControl device for grinding machines for multi-edged tools, in particular for cutter heads
Die !Teuerung betrifft eine Steuervorrichtung für Schleifmaschinen für mehrschneidige Werkzeuge, insbesondere für Messerköpfe. Bs ist bei derartigen Schleifmaschinen notwendig, daß insbesondere der in Richtung der Messerkopfachse planseitig zum Messerkopf gemessene Rundlauffehler der SFebenschneiden und Schneidecken nicht größer als 0,005 mm ist. Um die erforderte Laufgenauigkeit schleiftechnisch zu erreichen, erfolgt bisher selbst bei den sogenannten Messerkopf-Schleifautomaten die Zustellung der Schleifscheibe in ihrer zeitlichen Begrenzung und ihrer Größe nach von Hand. Auch wird bisher der Eilvorgang des Messerkopfes von Hand ein- und ausgeschaltet. Hierbei muß jeweils ebenfalls von Hand mit einer üblichen Meßuhr die erreichte Laufgenauigkeit der Schneiden mit der geforderten Laufgenauigkeit gemessen und diese miteinander verglichen werden.The price increase relates to a control device for grinding machines for multi-edged tools, especially for cutter heads. In grinding machines of this type, it is necessary, in particular, that the plane side in the direction of the cutter head axis Concentricity errors of the S flat cutting edges measured to the cutter head and cutting corners is no larger than 0.005 mm. In order to achieve the required running accuracy in terms of grinding technology, takes place so far even with the so-called cutter head grinding machines the delivery of the grinding wheel in terms of time Limitation and size by hand. Up to now, the rapid process of the cutter head has also been switched on and off manually. In this case, the running accuracy of the cutting edges with the required running accuracy must also be achieved by hand with a conventional dial gauge Running accuracy is measured and these are compared with each other.

Der Feuerung liegt die Aufgabe zugrunde, "bei Schleif maschinen für mehrschneidige Werkzeuge eine Steuervorrichtung zu schaffen, mit der die Zustellung der Schleifscheibe und gegebenenfalls die Teilbewegung des Werkzeugträgers selbsttätig auf Grund des Vergleiches mit dem Sollwerk der Laufgenauigkeit erfolgt.The firing is based on the task "in grinding machines to create a control device for multi-edged tools, with the infeed of the grinding wheel and possibly the partial movement of the tool carrier automatically based on the comparison with the target movement of the running accuracy he follows.
Gelöst wird diese Aufgabe nach der Feuerung dadurch, daß zum Abtasten der Werkzeugschneiden eine Meßuhr mit einstellbaren Kontakten vorgesehen und zwischen dem Zustellmotor für die Schleifscheibe und dem die Teilbewegung oder auGh eine andere Bewegung des Messerkopfes bewirkenden Motor ein von der Meßuhr beeinflußter Verstärker mit Zählwerk angeordnet wird. Mit Hilfe einer solchen Vorrichtung wird die wirkliehe Lage der zu schleifenden Werkzeugschneiden meßtechnisch ermittelt, mit der angestrebten Lag© der zu schleifenden Werkzeugschneiden verglichen und die Schleifscheibe und sonstige Elemente der Schleifmaschine werden solange zugestellt oder angetrieben, bis der eingestellte Sollwert der Werkzeugschneidenlage erreicht ist.This task is solved after the firing in that the Scanning the tool cutting a dial gauge with adjustable contacts is provided and between the feed motor for the Grinding wheel and the partial movement or another Movement of the cutter head causing motor an amplifier influenced by the dial gauge with counter is arranged. With With the help of such a device, the real position of the Tool cutting edges to be ground determined by measurement, with the desired position of the tool cutting edges to be ground compared and the grinding wheel and other elements of the grinding machine are fed or driven as long as until the set target value of the tool cutting edge position is reached.
Bei der praktischen Ausführung kann der Meßstift der Meßuhr mit einer verschleißfesten Kufe od. dgl. versehen sein, damit der Meßstift beim Schalten des Messerkopfes durch das näehste Messer wieder in seine Meßlage zurückgeführt wird. Die Meßuhr selbst kann a^· einem einstellbaren Meßarm angeordnet werden,In the practical version, the measuring pin of the dial gauge can be provided with a wear-resistant runner or the like, so that the measuring pin is returned to its measuring position by the closest knife when the cutter head is switched. The dial gauge even an adjustable measuring arm can be arranged,

Der Meßstift 3^- der Meßuhr ist in bekannter Weise mit verschiebbaren und einstellbaren elektrischen Kontaktstücken 5 ausgerüstet. Am vorderen Ende des Meßstiftes 3 befindet sich eine verschleißfeste Kufe 6, die dazu dient, beim Schalten des Messerkopfes von einem Messer zum anderen den durch eine leichte Feder belasteten Meßstift 3a entgegen der leder in die Meßlage zurückzudrücken.The cutter head 1 is placed in a known manner on a switchable carrier 2 of the machine. For the control is a dial gauge 3 is provided, which is arranged on an adjustable measuring arm and conveniently adjusted with the help of the joints can. The measuring pin 3 ^ - the dial gauge is in a known manner with sliding and adjustable electrical contact pieces 5 equipped. At the front end of the measuring pin 3 is a wear-resistant runner 6, which is used when switching the Cutter head from one knife to the other, the measuring pin 3a loaded by a light spring against the leather in the measuring position to push back.
Die Kufe 6 legt sich gegen die Schneide des Messers 7 an, bei dem es sich beispielsweise um ein Fräsmesser handelt, das sich in der Halterung 1a des Messerkopfes 1 befindet.The runner 6 rests against the cutting edge of the knife 7, which is, for example, a milling knife that is located in the holder 1 a of the cutter head 1.
Die Meßuhr 3 steht über eine Leitung 8 mit einem Verstärker in Verbindung, der auf ein Zählwerk 10 einwirkt. Dieses Zählwerk steuert den Beginn und das Ende oder auch die Größe derThe dial gauge 3 is connected to an amplifier via a line 8 in connection, which acts on a counter 10. This counter controls the beginning and the end or the size of the
