Description
Die Neuerung betrifft eine Werkzeugbearbeitungsmaschine mit einem Schaltteller, wie er in CNC-Rundtaktfertigungsautomaten zur Werkzeugbearbeitung eingesetzt wird.The innovation concerns a machine tool with an indexing table like that used in CNC rotary production machines is used for tool processing.
Der Schaltteller weist hierbei eine Antriebseinrichtung zum Antrieb einer auf der Antriebsachse des Schalttellers sitzenden Spannzangentrommel auf. Die Spannzangentrommel weist eine zumindest annähernd zylindrische Gestalt auf mit Werkzeugaufnahmeöffnungen, die an Ihrer Umfangsfläche verteilt sind. Eine Spannzangentrommel kann beispielsweise sechzehn Bearbeitungsstationen haben. Übliche Größenabmessungen solcher Spannzangentrommeln liegen zwischen 800 und 1400 mm.The switch plate has one Drive device for driving a on the drive axis of the Control plate seated collet drum. The collet drum has one at least approximately cylindrical shape with tool holder openings distributed around its circumferential surface. A collet drum can, for example, have sixteen processing stations to have. Usual size dimensions Such collet drums are between 800 and 1400 mm.
In diese Werkstückaufnahmen werden die zu bearbeitenden Werkstücke eingespannt und von den Bearbeitungseinheiten bearbeitet. Nach einem erfolgten Arbeitsgang wird die Spannzangentrommel über den Spannteller zur nächsten Bearbeitungsstation gedreht, so dass der nächste Bearbeitungsschritt am Werkstück erfolgen kann.The workpieces to be machined are placed in these workpiece holders workpieces clamped and processed by the processing units. After one operation is carried out, the collet drum is over the Clamping plate to the next Machining station rotated so that the next machining step on workpiece can be done.
Problematisch bei dieser Verfahrensweise ist die sogenannte Nebenzeit, d. h. Totzeit, während der das Werkstück nicht bearbeitet werden kann. Dies liegt daran, weil die Spannzangentrommel in dieser Zeit gedreht werden muss. Diese Zeit wird auch häufig als „Schalttellernebenzeit" bezeichnet.Problematic with this procedure is the so-called idle time, i.e. H. Dead time during which the workpiece is not can be edited. This is because the collet drum must be rotated during this time. This time is also often referred to as "switch plate secondary time".
Hier setzt die vorgeschlagene Neuerung an.This is where the proposed innovation comes in on.
Der Erfindung liegt die Aufgabe zugrunde, bei einer Werkzeugmaschine mit einem Schaltteller bei einer Minimierung der Nebenzeiten die Bearbeitungsmöglichkeiten zu erhöhen.The invention is based on the object a machine tool with an indexing table while minimizing the non-productive times to increase the processing options.
Gelöst wird diese Aufgabe durch die Merkmale des Patentanspruchs 1.This task is solved by the features of claim 1.
Es wird eine Werkzeugbearbeitungsmaschine mit einem Schaltteller vorgeschlagen, der mindestens zwei Spannzangentrommeln antreibt. Die Spannzangentrommeln sind hierbei übereinander angeordnet und sitzen auf der Antriebsachse des Schalttellers auf.It becomes a machine tool proposed with an indexing plate, the at least two collet drums drives. The collet drums are arranged one above the other and sit on the drive shaft of the table top.
Der wesentliche Vorteil dieser Idee besteht darin, daß die Nebenzeiten auf die Zeit für das Vertikalverfahren der Bearbeitungsspindel von der ersten zur zweiten Spannzangentrommel oder umgekehrt reduziert werden kann. Während z. B. auf der unteren Spannzangentrommel gearbeitet wird, kann die obere Spannzangentrommel eine Position weiterschalten. Ein weiterer Vorteil besteht darin, daß einfachere Werkzeugaufnahmeöffnungen in den Spannzangentrommeln vorgesehen werden können. Dies deshalb, weil beispielsweise in der unteren Spannzangentrommel lediglich solche Öffnungen für die Werkzeugaufnahme vorzusehen sind, die ein Einstecken des Werkzeuges von vorn erlauben und in die andere Spannzangentrommel Werkzeugaufnahmeöffnungen aufgenommen sind, die die Aufnahme des Werkzeuges von der rückwärtigen Seite ermöglichen.The main advantage of this idea is that the Non-productive times on time for the vertical movement of the machining spindle from the first to the second collet drum or vice versa. While z. B. on the lower collet drum, the upper Advance the collet drum one position. Another advantage is that simpler Tool receiving openings can be provided in the collet drums. This is because, for example only such openings in the lower collet drum for the tool holder are to be provided which allow the tool to be inserted from the front and tool holder openings in the other collet drum are included, the tool holder from the rear side enable.
Eine Prinzipskizze der vorgeschlagenen Werkzeugbearbeitungsmaschine mit übereinander angeordneten Spannzangentrommeln ist in der beiliegenden Figur dargestellt.A schematic diagram of the proposed machine tool with one above the other Collet drums are shown in the attached figure.
Die Vorteile der vorgeschlagenen Werkzeugbearbeitungsmaschine werden nachfolgend am Beispiel einer Werkzeugbearbeitungsmaschine mit sechzehn Stationen näher beschrieben:The advantages of the proposed Tool processing machines are shown below using the example of a Tool processing machine with sixteen stations described in more detail:
Eine heute übliche Schalttellermaschine mit sechzehn Stationen weist sechzehn Spannvorrichtungen und damit sechzehn Werkzeugaufnahmeöffnungen am Umfangsrand der Spannzangentrommel auf. Die einzelnen Spannzangentrommeln liegen hierbei auf gleicher Höhenlinie und sind im Radius um je 16/360° aufgeteilt angeordnet. Eine solche Anordnung ist verhältnismäßig voluminös und groß und hat also einen großen Durchmesser. Dieser große Durchmesser führt zugleich zu einem verhältnismäßig hohen Massenträgheitsmoment und damit zu länger notwendigen Schaltzeiten. Die Schaltzeit und die sich daraus ergebende Umspannzeit liegt bei ca. 1,5 sec., die als reine unproduktive Nebenzeit in die Stückzeitberechnung mit eingehen.A table top machine common today with sixteen stations has sixteen fixtures and so sixteen tool holder openings on the peripheral edge of the collet drum. The individual collet drums lie on the same contour and are divided in the radius by 16/360 ° arranged. Such an arrangement is relatively voluminous and large and therefore has a large diameter. This big diameter leads at the same time to a relatively high Moment of inertia and therefore too long necessary switching times. The switching time and the resulting one The span time is approx. 1.5 sec., Which is a pure unproductive idle time in the piece time calculation come in with.
Durch die vorgeschlagene übereinanderliegende Anordnung wären zur Bearbeitung von sechzehn Werkzeugen nur zwei über einander angeordnete Spannzangentrommeln mit jeweils acht Stationen notwendig. Dies bedingt einen kleineren Durchmesser der beiden Spannzangentrommeln, was vorteilhafterweise zu einem kleineren Massenträgheitsmoment und schnelleren Schaltzeiten führt.By the proposed one above the other Arrangement would be for machining sixteen tools, only two superimposed Collet drums with eight stations each are necessary. This requires a smaller diameter of the two collet drums what advantageously to a smaller moment of inertia and faster Switching times.
Je nach Aufbau der Werkzeugbearbeitungseinrichtung kann durch vertikales Verfahren der Bearbeitungsmaschinen zuerst oben und dann auf der unteren Spannzangenvorrichtung gearbeitet werden. Somit wird die im Eilgang zu verfahrende vertikale Bewegung der Bearbeitungseinrichtung, z. B. ein Bohrer, der in das in der Werkzeugaufnahmevorrichtung der Spannzangentrommel sitzende Werkstück ein Loch bohrt, als Nebenzeit zu rechnen sein. Des weiteren kann durch wechselweise Schaltung der acht oberen und acht unteren Vorrichtungen die als Nebenzeit geltende Schaltzeit in der Stückzeitkalkulation weitgehend vernachlässigt werden.Depending on the structure of the tool processing facility can be done by moving the processing machine vertically first worked on top and then on the lower collet device become. Thus the vertical movement to be traversed in rapid traverse the processing device, e.g. B. a drill in the in the Tool holder of the collet drum seated workpiece a hole bores to be counted as off-time. Furthermore, alternately Switching of the eight upper and eight lower devices as idle time applicable switching time in the piece time calculation largely neglected become.
Weitere Vorteile der vorgeschlagenen Werkzeugbearbeitungsmaschine sind:Other advantages of the proposed Machine tools are:
- 1. Der obere und untere Spannvorrichtungsring wird wechselweise geschaltet, so daß die Schaltzeit somit keine Nebenzeit mehr ist, sondern in die Hauptzeit mit eingeht. Dies bedingt jedoch, daß am Beispiel von acht Spannvorrichtungen ein Werkstück mit acht Stationen fertig bearbeitet werden kann. Es laufen somit immer zwei Werkstücke gleichzeitig durch die Werkzeugbearbeitungsmaschine.1. The upper and lower clamping device ring is switched alternately, so that the switching time is no longer an idle time, but is included in the main time. However, this requires that using the example of eight clamping devices Workpiece can be finished with eight stations. This means that two workpieces always run through the machine tool at the same time.
- 2. Der obere und untere Spannvorrichtungsring, also die Spannzangentrommeln, werden gleichzeitig geschaltet. Hierdurch ergibt sich eine Konfiguration um zwei Werkstücke parallel zu bearbeiten. Dies ergibt eine doppelte Ausbringung an Werkstücken und damit eine verdoppelte Stückleistung.2. The upper and lower collet ring, ie the collet drums, are switched simultaneously. This results in a configuration by two workpieces to be processed in parallel. This results in a double output on workpieces and a doubled piece output.
- 3. Die beiden Spannzangentrommeln werden gleichzeitig geschaltet. Hierdurch ergibt sich eine Konfiguration an der unteren Spannzangentrommel, bei der die Vorderseite des Werkstückes bearbeitet wird. An der oberen Spannzangentrommel kann dagegen das Werkstück mit der Vorderseite eingespannt und daher an der Rückseite bearbeitet werden. Dies ergibt eine komplette Bearbeitung in einem Maschinendurchlauf.3. The two collet drums are switched simultaneously. This results in a configuration on the lower collet drum, where the front of the workpiece is machined. At the The upper collet drum, on the other hand, can hold the workpiece Clamped on the front and therefore processed on the back. This results in complete machining in one machine run.
Insgesamt wird durch die vorgeschlagene Werkzeugbearbeitungsmaschine ein kleinerer Bauraum erzielt, wodurch einerseits der Platzbedarf für die Maschine erniedrigt werden kann und andererseits die Fixkosten der Maschine reduziert werden können.Overall, the proposed machine tool a smaller installation space is achieved, which on the one hand requires space for the Machine can be lowered and on the other hand the fixed costs of the Machine can be reduced.
