Abstract

The present invention relates to a changing device for automatic replacement of modular cutting units in CNC machine tools. The cutting units are guided into or out of the machine tool's work zone in a loading attachment by means of a gripping fork. The invention is characterised by the device comprising a magazine like a loading pallet and several linear-shaped holders in the magazine at a set distance from one another. Each holder is provided with mechanisms for locating and holding in place several cutting units arranged in a row. The magazine is mounted on an incremental feed device in order to advance a specific holder to the changing position. A lifting device can raise the holder in the changing position from the magazine to a precisely located position above the other holders, where the cutting units can be reached by the gripping fork of the loading attachment.

Description

Die vorliegende Erfindung bezieht sich auf eine Wechsel­ vorrichtung zum automatischen Austauschen von modulari­ sierten Schneideinheiten in CNC-gesteuerten Werkzeug­ maschinen.The present invention relates to a change device for the automatic exchange of modulari based cutting units in CNC-controlled tools machinery.

Schneideinheiten für Werkzeugmaschinen werden immer mehr in modularisierter Form hergestellt, indem verschiedene Schneideinheiten, wie Drehstähle, Bohrfutter usw., mit einer Spannvorrichtung ausgestattet werden, die in einer Spanneinheit, beispielsweise im Werkzeughalter einer Revol­ verdrehbank, verwendet werden kann. Diese Schneidein­ heiten gestatten schnelles Wechseln und Umrüsten und kön­ nen dazu beitragen, die Werkzeugmaschine mehr flexibel auszustatten. Sie lassen sich auch automatisch handhaben, was automatisches Austauschen eines verschlissenen Werk­ zeuges oder Austausch gegen eine andere Art von Werkzeug beim Umrüsten gestattet.Cutting units for machine tools are becoming more and more made in modularized form by different Cutting units such as turning tools, drill chucks etc. with a clamping device can be equipped in a Clamping unit, for example in the tool holder of a revolver lathe, can be used. This cutting units allow quick changing and retrofitting and can contribute to making the machine tool more flexible equip. They can also be handled automatically, what automatic replacement of a worn out work or exchange for another type of tool allowed when converting.

Die Schneideinheiten müssen jedoch so magaziniert werden, dass sie leicht durch die Greifgabel der Ladevorrichtung greifbar sind, die dieselben in die Arbeitszone der Maschine hinein- bzw. aus derselben herausführen soll, so dass sie in Wechselstellung genau lokalisiert sind, sowie dass sie auf einfache Art und Weise zur und von der Maschine auf einer Palette nach Art einer Ladepalette (Europa-Palette) transportierbar sind.However, the cutting units have to be that they can easily be gripped by the loading fork are tangible, the same in the working zone of the machine should lead in or out of the same, so that it are exactly localized in the change position, as well as that in a simple way to and from the machine a pallet like a loading pallet (European pallet) are transportable.

Erfindungsgemäss wird dieses Problem dadurch gelöst, dass die Wechselvorrichtung ein Magazin nach Art einer Lade­ palette umfasst, sowie mehrere im Magazin in vorgegebenem Abstand voneinander vorgesehene linealförmige Halter, die jeweils mit einem Organ versehen sind, um mehrere in einer Reihe vorgesehene Schneideinheiten festzuhalten und zu lokalisieren, eine Schrittvorschubvorrichtung, auf der das Magazin zum Verfahren eines bestimmten Halters in eine Wechselstellung angebracht ist, sowie eine Hebevorrich­ tung, um den Halter in Wechselstellung vom Magazin hoch in eine genau vorgegebene Lage über der Ebene der übrigen Halter anzuheben, in der die Schneideinheiten durch die Greifgabel der Ladevorrichtung greifbar sind.According to the invention, this problem is solved in that the changing device is a magazine like a drawer range includes, as well as several in the magazine in predetermined Spacers provided spaced from each other, the are each provided with an organ to make several in one Row intended to hold and close cutting units locate a step feeder on the the magazine for moving a particular holder into one Change position is attached, as well as a lifting device the holder in the change position from the magazine  in a precisely specified position above the level of the rest Lift holder in which the cutting units through the Gripping fork of the loading device are within reach.

Die Erfindung sei nun näher unter Bezugnahme auf beiliegende Zeichnungen erläutert, die eine Ausführungsform der erfin­ dungsgemässen Wechselvorrichtung darstellen.The invention will now be described in more detail with reference to the accompanying Drawings explained that an embodiment of the inventions represent change device according to the invention.

Die Schneideinheiten 1 sind auf einem linealförmigen Hal­ ter 2 angeordnet. Die Halter sind mit ein paar Pinnen 3 zum Lokalisieren und einem anderen Paar Pinnen 4 zum Fest­ halten der Schneideinheiten versehen. Die linealförmigen Halter 2 sind im Magazin 5 in bestimmten Stellungen pla­ ciert und auf senkrechten Steuerpinnen 6 in vorgegebenem Abstand oder mit einer Teilung 7 voneinander geführt. Aus­ serdem sind die Schneideinheiten in einer bestimmten Tei­ lung voneinander auf dem Halter 2 angeordnet, so dass die Schneideinheiten auf diese Art und Weise in ein Koordina­ tensystem für das Magazin eingeordnet sind.The cutting units 1 are arranged on a linear Hal 2 ter. The holders are provided with a few tiller 3 for locating and another pair of tiller 4 for holding the cutting units. The ruler-shaped holder 2 are placed in magazine 5 in certain positions and guided on vertical control spiders 6 at a predetermined distance or with a division 7 from one another. In addition, the cutting units are arranged in a certain part of each other on the holder 2 , so that the cutting units are arranged in this way in a coordinate system for the magazine.

Das Magazin ist auf einer Schrittvorschubvorrichtung 12 an­ gebracht, die das ganze Magazin in eine Wechselstellung ver­ fahren kann. Der sich in der Wechselstellung der Maschine befindende Halter 2 wird durch eine Hebevorrichtung 9 aus dem Magazin in eine Ebene oberhalb der übrigen Halter an­ gehoben. Die Hebevorrichtung umfasst neben dem Magazin vorgesehene Hebezapfen 9, die durch Öffnungen in den Seiten­ wänden des Magazines in Eingriff mit entsprechenden Aus­ nehmungen in den Stirnseiten des jeweiligen Halters kommen können. Dadurch, dass der Halter in Wechselstellung in eine genau vorgegebene Stellung oberhalb der übrigen Hal­ ter angehoben wird, werden die Schneideinheiten auf diesem Halter der Greifgabel 15 der Ladevorrichung 14 zugänglich. Welche Schneideinheit zu holen ist bzw. welche freie Stel­ lung beim Rückführen auszunützen ist, wird durch das Pro­ gramm der Werkzeugmaschine gesteuert. The magazine is placed on a step feed device 12 , which can move the entire magazine into a changing position. The holder 2 in the changing position of the machine is lifted by a lifting device 9 out of the magazine into a plane above the other holders. The lifting device comprises in addition to the magazine provided lifting pin 9 , which can come through openings in the side walls of the magazine into engagement with corresponding recesses in the end faces of the respective holder. Characterized in that the holder is raised in a changing position in a precisely predetermined position above the other Hal ter, the cutting units on this holder of the gripping fork 15 of the loading device 14 are accessible. The machine tool's program controls which cutting unit is to be fetched and which free position is to be used when returning.

Die Erfindung ist natürlich nicht auf die oben beschriebene und auf den Zeichnungen dargestellte Ausführungsform be­ grenzt sondern lässt sich im Rahmen der Patentansprüche ab­ wandeln.The invention is of course not based on the one described above and be shown in the drawings embodiment delimits but can be within the scope of the claims walk.
