Description

embodiment

Die Erfindung wird nachstehend an einem Ausführungsbeispiel näher erläutert. In der zugehörigen Zeichnung zeigen in schematischer Darstellung:The invention will be explained in more detail using an exemplary embodiment. In the accompanying drawing show in a schematic representation:

Fig. 1: eine Vorderansicht des Werkzeugmagazins,1 is a front view of the tool magazine,

Fig. 2: einen Schnitt A-A nach Fig. 1.2 shows a section A-A of FIG. 1.

Auf einem Sockel 1 ist der um die senkrechte Achse 2 drehbewegliche Magazinkörper 3 angeordnet. Dieser kann mit einer oder mehreren Speicherflächen 4 ausgeführt werden, was vom jeweiligen Einsatzfall und der daraus resultierenden Anzahl zu speichernder Werkzeuge 5 bestimmt wird, die im Ausführungsbeispiel Mehrspindelbohrköpfe sind. Jede Speicherfläche 4 besitzt einen quadratischen Grundriß mit jeweils vier Speicherplätzen 6. Diese sind als nach der Übergabeseite hin offene Kammern 7 ausgebildet. In jeder der Kammern 7 sind an deren äußerer seitlicher Innenwand 8 Werkzeugaufnahmen 9 befestigt, die durch in die Werkzeuge 5 eingreifende Führungsschienen 10,11 gebildet werden.On a base 1 of the rotatable about the vertical axis 2 magazine body 3 is arranged. This can be performed with one or more storage areas 4, which is determined by the particular application and the resulting number of stored tools 5, which are in the embodiment Mehrspindelbohrköpfe. Each memory area 4 has a square plan with four memory locations each. These are designed as chambers 7 that are open towards the transfer side. In each of the chambers 7 8 tool holders 9 are attached to the outer side inner wall, which are formed by engaging in the tools 5 guide rails 10,11.

Fig. 2 verdeutlicht, daß die Werkzeugaufnahmen 9 der jeweils benachbarten Speicherplätze 6 rechtwinklig zueinander angordnet sind, wodurch eine hohe Speicherdichte erreicht wird, was wiederum die Reduzierung des magazinbedingten Platzbedarfes auf ein Minimum ermöglicht.Fig. 2 illustrates that the tool holders 9 of the respective adjacent memory locations 6 are angordnet at right angles to each other, whereby a high storage density is achieved, which in turn allows the reduction of the magazine-related space requirements to a minimum.

Aus den Fig. 1 und 2 ist zu erkennen, daß das Lösungsprinzip im wesentlichen einen unmittelbaren Anschluß der Führungsschienen 10,11 an komplementäre maschinenseitige Führungen zur Aufnahme des Werkzeuges 5 in einer nicht dargestellten Maschine erlaubt. Damit ergibt sich eine erhebliche Vereinfachung des Werkzeugwechsels und der dazu erforderlichen technischen Mittel, die im Interesse einer aufwandsarmen Gestaltung des Werkzeugmagazins der Maschine zugeordnet werden, da sie dadurch für alle Speicherplätze 6 entfallen. Die Speicherflächen 4 sind vorzugsweise in einem festen Abstand zueinander angeordnet, ihre Anzahl wird demzufolge vom Einsatzfall und dem Senkrechtkurs der Maschine bestimmt. Eine für bestimmte Anwendungsfälle denkbare Höhenverstellbarkeit der Speicherflächen 4 ist technisch ohne weiteres möglich.From FIGS. 1 and 2 it can be seen that the solution principle essentially allows an immediate connection of the guide rails 10,11 to complementary machine-side guides for receiving the tool 5 in a machine, not shown. This results in a considerable simplification of the tool change and the necessary technical means, which are assigned in the interest of a low-cost design of the tool magazine of the machine, since they account for all memory locations 6. The storage areas 4 are preferably arranged at a fixed distance from each other, their number is therefore determined by the application and the vertical course of the machine. A conceivable height adjustment of the storage areas 4 for certain applications is technically possible without further ado.

Die Vorteile der Erfindung bestehen insbesondere darin, daßThe advantages of the invention are in particular that

— bei Erzielung einer vergleichsweisen hohen Speicherkapazität der Platzbedarf für das Werkzeugmagazin verhältnismäßig gering ist,If the space required for the tool magazine is comparatively small when a comparatively high storage capacity is achieved,

— eine Vereinfachung der ÜbergabeAnahmebedingungen zwischen Maschine und Magazin erreicht wird.- A simplification of the transfer acceptance conditions between the machine and magazine is achieved.

Field of application of the invention

The invention relates to a tool magazine, insbesndere automatically replaceable Mehrspindelbohr- and machining heads of larger design, with rotatable about a common axis memory locations, which can be brought into transfer position to a headstock and a guide, for the purpose of a radially extending to the work spindle of the machine WerkzeugübergabeZ removal is in alignment with an in-machine lead. The preferred field of application are machining centers.

Characteristic of the known technical solutions

Automatically exchangeable Mehrspindelbohr- and machining heads, which are not stored in the usual tool magazine of the machine due to their relatively large space requirements, are usually included in a second, specially tailored to them magazine, which can be both an integral part of the machine or this as a separate unit is provided.

It is known to form tool magazines of the type mentioned turret-like and evenly distributed on its circumference to provide planar systems for receiving the processing heads, which are in transfer position with complementary guides of the machine / headstock in accordance (DE-OS 3009357, machining center XB 306 the Fa Ex-CeII-O, DE / Prospectus).

With regard to expansion, this solution principle leads in particular to a relatively large design of the magazines, when their storage level runs horizontally. This is of significant disadvantage where the magazines are to be provided as a separate unit to increase the flexibility of machining centers and, as is very often the case, only a very limited space is available. Moreover, such a design of the magazine complicates the coupling of the tools to the machine and makes the tool change more complex (see, for example, DE-OS 1813989). The disadvantage of the relatively large footprint also has the one shown in DE-OS 2233657 and formed as an angular swivel body to a horizontal axis movable tool magazine for spindle and machining heads, which also has a very limited storage capacity and measured thereon, requires considerable effort. Linear memory for processing heads, as used for example in flexible manufacturing systems (eg PFZ1500 Fa. KoIb, DE / Prospekt, Flex Center 320 from the company Ex-CeII-O Corporation, US / Prospectus) are also very space consuming, usually require extensive handling technology and are therefore mainly only for very specific applications.

Object of the invention

The aim of the invention is to ensure a sufficient storage capacity while minimizing the space requirement and to simplify the conditions for tool transfer / removal.

Essence of the invention

The object of the invention is to provide a tool magazine, in particular automatically replaceable Mehrspindelbohr- and machining heads of larger design, with a common axis rotatable memory locations, which can be brought into transfer position to a headstock and a guide, for the purpose of a radial to the work spindle of the machine extending tool transfer / removal with a machine-internal guide is in alignment, the arrangement of the tools is such that at maximum utilization of the circumscribed by the magazine cross-section storage area is given a substantially immediate connection to the coupling point of the machine.

According to the invention the object is achieved in that there are four memory locations on a memory area with a square plan, wherein the tool holders of the respective adjacent memory locations are arranged at right angles to each other.

According to a further feature of the invention, the memory locations are formed as open to the transfer side chambers, at the outer side inner wall, the tool holder are mounted as engaging in the tools guide rails.
