Abstract
Description
Die vorliegende Erfindung betrifft ein Verfahren zum Bearbeiten eines Werkstückes, mit einem an einem Werkzeugkopf montierten Werkzeug, mittels dem eine Aussparung oder ein Durchbruch an dem Werkstück hergestellt wird, und eine entsprechende Vorrichtung zur Herstellung einer Aussparung oder eines Durchbruches.The The present invention relates to a method for processing a Workpiece with a mounted on a tool head tool, by means of made a recess or a breakthrough on the workpiece is, and a corresponding device for producing a recess or a breakthrough.
Im Bereich der Metall- und Kunststoffverarbeitung, werden häufig Materialien mit CNC-gesteuerten Werkzeugmaschinen bearbeitet. Dabei werden insbesondere Bauteildurchbrüche hergestellt, beispielsweise mittels eines Lasers, Plasmaschneiders, Fräsers, Bohrers oder eines Stanzwerkzeuges in das Werkstück eingebracht. Im Rahmen der industriellen Serienfertigung ist es dabei nicht vollständig möglich, Fehler bei der Herstellung solcher Durchbrüche auszuschließen, sodass Material in dem Durchbruch verbleiben kann, das den weiteren Bearbeitungsvorgang behindert. Auch wenn solche Fehler nur selten auftreten, behindern sie den weiteren Verfahrensablauf und können bei einer automatischen Weiterverarbeitung des Werkstückes, beispielsweise im Automobilbereich, für einen Stillstand einer Produktionsanlage sorgen.in the The field of metal and plastic processing, often become materials machined with CNC-controlled machine tools. In doing so, in particular Component breakthroughs manufactured, for example by means of a laser, plasma cutter, milling cutter, drill or a punching tool introduced into the workpiece. As part of the industrial mass production, it is not completely possible, mistakes to exclude in the manufacture of such breakthroughs, so Material can remain in the breakthrough, the further processing with special needs. Even if such errors rarely occur, they hinder They further process and can be used in an automatic Further processing of the workpiece, For example, in the automotive sector, for a stoppage of a production plant to care.
Es ist daher Aufgabe der vorliegenden Erfindung ein Verfahren und eine Vorrichtung zum Bearbeiten von Werkstücken zu schaffen, mittels dem eine effektive Bearbeitung von Werkstücken möglich ist und eventuelle Fehler frühzeitig erkennbar sind.It is therefore an object of the present invention, a method and a To provide a device for machining workpieces, by means of a effective machining of workpieces is possible and possible errors early are recognizable.
Diese Aufgabe wird mit einem Verfahren mit den Merkmalen des Anspruches 1 und mit einer Vorrichtung mit den Merkmalen des Anspruches 4 gelöst.These The object is achieved by a method having the features of the claim 1 and solved with a device having the features of claim 4.
Bei dem erfindungsgemäßen Verfahren wird zunächst mittels dem Werkzeug eine Aussparung oder ein Durchbruch an dem Werkstück hergestellt und anschließend mittels einem am Werkzeugkopf montierten Sensor geprüft, ob die Aussparung oder der Durchbruch in einer vorbestimmten Form hergestellt und eine Abfallteil entfernt wurde. Eine solche Durchstoßkontrolle für Bauteildurchbrüche bietet eine Gewährleistung, dass Fehler bei der Herstellung sofort erkannt werden und entsprechende Maßnahmen ergriffen werden können. Die Prüfung kann umgehen nach der Bearbeitung des Werkstückes erfolgen, sodass sich die Bearbeitungszeit an dem Werkzeug nur minimal verlängert oder sogar gleich bleibt.at the method according to the invention will be first by means of the tool a recess or a breakthrough on the workpiece produced and then checked by means of a sensor mounted on the tool head, whether the Recess or breakthrough made in a predetermined shape and a waste part was removed. Such puncture control for component breakthroughs offers one warranty, that errors in the production are recognized immediately and corresponding activities can be taken. The exam can be done after the machining of the workpiece so that itself the processing time on the tool only minimally extended or even stays the same.
Vorzugsweise erfolgt die Prüfung während einer Bewegung des Werkzeuges weg von dem Werkstück, sodass die ohnehin erforderliche Bewegung des Werkzeuges gleichzeitig ausgenutzt wird, um eine Durchstoßkontrolle durchzuführen. Dadurch kann die Bearbeitungszeit an dem Werkzeug besonders effektiv genutzt werden. Die Prüfung kann dabei über eine optische Sende- und Empfangseinrichtung erfolgen, mittels der die Reflektion von Lichtstrahlen durch das Werkstück erfassbar wird.Preferably the exam takes place during one Movement of the tool away from the workpiece, so that the anyway required Movement of the tool is simultaneously exploited to puncture control perform. This makes the processing time on the tool particularly effective be used. The exam can over it an optical transmitting and receiving device take place by means of the reflection of light rays can be detected by the workpiece becomes.
Gemäß einer erfindungsgemäßen Vorrichtung ist ein Sensor am Werkzeugkopf montiert, mittels dem nach einer Entfernung des Werkzeuges vom Werkstück ermittelbar ist, ob an dem Werkstück die Aussparung oder der Durchbruch hergestellt wurde. Durch die unmittelbar benachbarte Anordnung von Sensor und Werkzeug ist es möglich, die Positionserfassung für das Werkzeug auch für den Sensor zu nutzen, sodass eine besonders sichere Erfassung des Durchbruches an dem Werkstück möglich ist, wobei kein weiteres Positionierungssystem an einer Maschine vorgesehen werden muss. Ferner kann der Sensor flexibel eingestellt wer den, sodass möglichst auch während der Bewegung des Werkzeugkopfes eine entsprechende Prüfung erfolgen kann.According to one Device according to the invention is a sensor mounted on the tool head, by means of a Removal of the tool from the workpiece can be determined, whether on the Workpiece the Recess or breakthrough was made. By the immediate adjacent arrangement of sensor and tool, it is possible, the Position detection for the tool also for to use the sensor, so that a particularly secure detection of the Breakthrough on the workpiece possible is, with no further positioning system on a machine must be provided. Furthermore, the sensor can be set flexibly who the, so possible even while the movement of the tool head carried out a corresponding test can.
Um die Bearbeitung des Werkstückes nicht zu beeinträchtigen, ist der Sensor vorzugsweise oberhalb beabstandet von dem Werkzeug angeordnet. Dabei kann auch ein schon im Einsatz befindlicher Werkzeugkopf mit einem entsprechenden Sensor oder mehreren Sensoren für die Durchstoßkontrolle nachgerüstet werden.Around the machining of the workpiece not to interfere the sensor is preferably spaced above the tool arranged. It can also be an already in use tool head with a corresponding sensor or several sensors for puncture control retrofitted become.
Vorzugsweise ist am Werkzeugkopf ein optischer Sensor und ein optischer Signalgeber montiert. Dabei können Sensor und Signalgeber auch zu einer Einheit zusammengefasst sein, die besonders einfach zu montieren und an eine Steuerung anzuschließen ist. Statt einer optischen Prüfung können am Werkzeugkopf auch ein kapazitiver Sensor, ein auf Ultraschall basierender Sensor oder andere Sensoren vorgesehen sein.Preferably is on the tool head an optical sensor and an optical signal generator assembled. It can Sensor and signal generator can also be combined into one unit, which is particularly easy to install and connect to a controller. Instead of a visual inspection can on the tool head also a capacitive sensor, one on ultrasound be provided based sensor or other sensors.
Die Erfindung wird nachfolgend anhand eines Ausführungsbeispiels mit Bezug auf die beigefügte Zeichnung näher erläutert. Es zeigt:The Invention will be described below with reference to an embodiment with reference to the enclosed Drawing closer explained. It shows:

Ferner ist es möglich, am Werkzeugkopf an verschiedenen Seiten mehrere Sensoren zu montieren, so dass bei einer Bewegung des Werkzeugkopfes nach oben die Prüfung durch eine schräg einfallenden Strahl von unterschiedlichen Seiten erfolgen kann. Dies schafft eine größere Flexibilität, da Bauteilkanten eines Werkstückes einen einzelnen einfallenden Strahl einmal unterbrechen können.Further Is it possible, to mount several sensors on the tool head on different sides, so that upon movement of the tool head up the test by an oblique incident beam can be made from different sides. This creates greater flexibility because of component edges a workpiece can interrupt a single incident beam once.
