Abstract

Control device on a sensor-integrated machine spindle (1) for process-controlled monitoring of the system and the clamping state of tools and/or tool holders in the working spindle of machine tools transfers measurement data recorded on the working side of the spindle end through the spindle onto a docking unit (9) consisting of an axial plug (7) and socket. Preferred Features: The docking unit is connected to the control unit of the machine.

Description

Die Erfindung betrifft eine Kontrolleinrichtung an einer sensorintegrierten Maschinenspindel zur prozesssicheren Überwachung der Plananlage und des Spannzustandes von Werkzeugen und/oder von Werkzeugaufnahmen in der Arbeitsspindel von Werkzeugmaschinen.The invention relates to a control device on a sensor-integrated Machine spindle for reliable monitoring of the plan system and the clamping state of tools and / or Tool holders in the work spindle of machine tools.

Bei der spangebundenen Fertigung auf Werkzeugmaschinen kommt unter den Bedingungen einer stetigen Leistungssteigerung und der damit einhergehenden erhöhten Drehzahlen der inneren Stabilität und Sicherheit der Werkzeugaufnahme eine besondere Bedeutung zu.When it comes to chip-based manufacturing on machine tools under the conditions of a constant increase in performance and with it accompanying increased speeds of internal stability and Safety of the tool holder is of particular importance.

Die Werkzeugaufnahme muss als eine der Voraussetzungen für einen sicheren Zerspanungsprozess jederzeit eine einwandfreie Plananlage des Werkzeuges garantieren und außerdem sicherstellen, dass der einmal vorgenommene Spannzustand zwischen Werkzeug und Maschinenspindel unverändert aufrechterhalten bleibt.The tool holder must be one of the prerequisites for one safe machining process at all times a perfect plan layout of the Guarantee tool and also ensure that the once made clamping state between tool and Machine spindle remains unchanged.

Vor allem dort, wo langauskragende Werkzeug Anwendung finden, wie z. B. im Werkzeug- und Formenbau, führt eine unzureichende bzw. unter dem Einfluss von Staub und Spänen beeinträchtigte und damit unvollkommene Plananlage zu Nachteilen, die den gesamten Spanungsprozess erheblich stören können.Especially wherever long cantilever tools are used, such as z. B. in tool and mold making, leads to an insufficient or under the influence of dust and chips and thus impaired imperfect plan layout to disadvantages that affect the entire Can significantly disrupt the cutting process.

Das Auftreten von Rundlauffehlern, Unwucht, Rattermarken sowie erhöhter Schneidenverschleiß sind die Folgen.The occurrence of concentricity errors, unbalance, chatter marks as well The consequences are increased cutting edge wear.

Es kommt demnach ersichtlich darauf an, den Erfordernissen einer genauen und sicher wirkenden Plananlage des Werkzeuges bzw. der Werkzeugaufnahme in der Maschinenspindel Rechnung zu tragen und Möglichkeiten vorzusehen, die eine verlässliche Kontrolle des Aufnahme- und Spannzustandes zu jeder Zeit des Spanungsprozesses zu schaffen in der Lage sind. It obviously depends on the needs of one precise and safe working plan layout of the tool or the Tool holder in the machine spindle and To provide possibilities for reliable control of the reception and to create a state of tension at any time during the cutting process are able.  

Herkömmlich bekannte Plananlagekontrollen, welche z. B. vermittels Wegmessender Drucklufteinrichtungen arbeiten, sind nach dem gemachten Erfahrungen der Anwender nicht zweckmäßig anwendbar und/oder genügen den derzeit wesentlich erhöhten Arbeitsansprüchen nicht mehr.Conventionally known plan plant controls, which z. B. mediated Path measuring compressed air devices are working according to the experiences made by users are not usable and / or meet the currently significantly higher work demands no more.

Der Erfindung liegt demgemäß die Aufgabe zugrunde, unter Verwendung von Komponenten der Mikroelektronik ein in die Maschinenspindel integrierbares Überwachungssystem für den sicheren Sitz, darunter insbesondere auch der Plananlage, von HSK Werkzeugaufnahmen in HSK-Maschinenspindeln zu schaffen, mit dem die Überwachung beider Zustandseigenschaften, nämlich der Plananlage und des Spannzustandes ermöglicht ist.The invention is accordingly based on the object using of microelectronic components into the machine spindle Integrable monitoring system for a secure fit, including especially the plan layout, from HSK tool holders in To create HSK machine spindles, with the monitoring of both State properties, namely the plan layout and the clamping state is possible.

Diese Aufgabe wird mit den im Patentanspruch 1 charakterisierten technischen Mitteln und deren Anordnung an der Maschinenspindel gelöst.This object is characterized in that in claim 1 technical means and their arrangement on the machine spindle solved.

Damit wurde eine unmittelbare praktizierbare Möglichkeit geschaffen den Anforderungen von Werkzeugmaschinenherstellern sowie von Spanntechnik- und Werkzeugherstellern und auch den Erwartungen der Anwender nach einen einfachen oder sicher wirkenden, beide Zustandseigenschaften erfassenden Kontrollmechanismus zu entsprechen. Gleichsam wird mit dieser neuen Lösung eine Lücke zu den konventionellen Überwachungssystem geschlossen.This created an immediate practicable possibility the requirements of machine tool manufacturers as well as Clamping technology and tool manufacturers and also the expectations of Users looking for a simple or safe-looking, both Control mechanism determining state properties correspond. At the same time, this new solution becomes a gap in the conventional surveillance system closed.

Die Erfindung soll nachstehend an einem Ausführungsbeispiel und der zugehörigen Zeichnung kurz erläutert werden.The invention is based on an embodiment and the associated drawing are briefly explained.

Die Zeichnung stellt das Prinzip der erfindungsgemäßen Kontrolleinrichtung dar. The drawing represents the principle of the invention Control device.  

Die in üblicher Bauart gestaltete Spindelwelle 1 trägt an ihrem arbeitsseitigem Ende den Spindeleinsatz 2 zur passgerechten Aufnahme der als HSK ausgeführten Werkzeugaufnahme 3. An der Stirnseite 4 des Spindeleinsatzes 2 sind die mit der Spindelwelle 1 rotierenden, aus vorzugsweise drei Einheiten bestehenden Wirbelstromsensoren 5 angeordnet, deren Sensorkabel 6 durch die Spindelwelle 1 hindurchgeführt sind und dort in eine Art Steckdose 7 münden.The designed in conventional type screw shaft 1 carries at its end the spindle arbeitsseitigem insert 2 to pass just accommodate the tool holder 3 constructed as HSK. On the front side 4 of the spindle insert 2 , the eddy current sensors 5 rotating with the spindle shaft 1 , preferably consisting of three units, are arranged, the sensor cables 6 of which are led through the spindle shaft 1 and open there into a kind of socket 7 .

Dieser Steckdose 7 ist eine mit entsprechendem Stecker 8 ausgestattete Andockeinheit 9 zugeordnet, von der die Weiterleitung der Messwerte an die maschineneigene Steuerungseinheit vorgenommen wird.This socket 7 is assigned a docking unit 9 equipped with a corresponding plug 8 , from which the measured values are forwarded to the machine's own control unit.

Durch die Wirbelstromsensoren 5 werden also sowohl die Planflächenanlage als auch der wirkende Spannzustand erfasst. Die Datenübertragung erfolgt dabei im Spindelstillstand über die Andockeinheit wobei im Falle eines gemessenen Fehlers kein Spindelanlauf erfolgt.The eddy current sensors 5 thus detect both the plane surface system and the effective clamping state. The data transfer takes place when the spindle is at a standstill via the docking unit. In the event of a measured error, no spindle starts.
