Beschreibung description
[0001] Die vorliegende Erfindung bezieht sich auf eine Bearbeitungsanlage mit einem Rundschalttisch und mindestens zwei Arbeitsstationen, wovon mindestens eine eine Rundschleifstation ist, gemäss Oberbegriff von Patentanspruch 1. Dabei ist die Anzahl der Bearbeitungsstationen so gewählt, dass ein Werkstück in einer Aufspannung fertig bearbeitet werden kann. Eine solche Anlage ist in der WO 01/34 342 beschrieben. The present invention relates to a processing plant with a rotary indexing table and at least two workstations, of which at least one is a cylindrical grinding station, according to the preamble of claim 1. In this case, the number of processing stations is selected so that a workpiece to be finished in one setting can. Such a system is described in WO 01/34 342.
[0002] Dabei kann das Werkstück auch innerhalb des Rundtaktes umgespannt werden, so dass eine Komplettbearbeitung beider Seiten möglich ist. Die Bearbeitung findet hauptsächlich durch Aussen-/Innenrund- und Planschleifen statt, wobei die Bearbeitungsprozesse auf allen Bearbeitungsstationen simultan stattfinden, wodurch eine hohe Produktivität und Wirtschaftlichkeit erreicht wird. In this case, the workpiece can be re-clamped within the rotary cycle, so that a complete machining of both sides is possible. The machining takes place mainly by external / internal cylindrical and surface grinding, whereby the machining processes take place simultaneously on all processing stations, whereby a high productivity and economic efficiency is achieved.
[0003] Die Arbeitsgenauigkeit wird in einem wesentlichen Teil durch die Positionier- und Wiederholgenauigkeit des Rundtaktschaittisches in den verschiedenen Arbeitspositionen bestimmt und die Streubreite in den verschieden Arbeitspositionen wirkt sich direkt auf die Massgenauigkeit am Werkstück aus. The working accuracy is determined in a substantial part by the positioning and repetition accuracy of the rotary indexing table in the various working positions and the spread in the different working positions directly affects the dimensional accuracy of the workpiece.
[0004] Statische und dynamische Einwirkungen wie Drehmomente, Reibung, Gewichte und wechselseitige Belastungen durch Kabelschlepps haben, trotz formschlüssiger Indexierung in der Hirthverzahnung, eine Positionsstreubreite am Bearbeitungspunkt von mehreren Mikrometer zur Folge. Static and dynamic effects such as torques, friction, weights and mutual loads by cable tractors have, despite positive indexing in the Hirth gearing, a position scatter at the processing point of several microns result.
[0005] Die Endbearbeitung von Werkstücken mit engsten Masstoleranzen, wie sie im Bereich der Kraftstoff-Einspritztechnik in grossen Mengen benötigt werden, sind deshalb auf Rundtaktmaschinen, wie sie heute bekannt sind, nicht herstellbar. Dies trifft sowohl auf die Rundtaktmaschine gemäss FR-A-1 549 215 als auch gemäss US-A-5 452 502 zu, die eine solche Präzision weder zulassen noch andeuten. The finishing of workpieces with tightest dimensional tolerances, as required in the field of fuel injection technology in large quantities, therefore, are not produced on rotary transfer machines, as they are known today. This applies both to the rotary transfer machine according to FR-A-1 549 215 and to US-A-5 452 502, which neither allow nor suggest such a precision.
[0006] Es ist von diesem Stand der Technik ausgehend Aufgabe der vorliegenden Erfindung, eine Rundtakt-Bearbeitungsmaschine anzugeben, die eine Feinbearbeitung erlaubt, die vorher nur mit linearen Bearbeitungsmaschinen erzielbar war. Diese Aufgabe wird mit der Rundtakt-Bearbeitungsmaschine gemäss Patentanspruch 1 erreicht. Ausführungsbeispiele und Verbesserungen sind in den abhängigen Ansprüchen definiert. It is from this prior art starting task of the present invention to provide a rotary indexing machine, which allows a fine machining, which was previously achievable only with linear processing machines. This object is achieved with the rotary indexing machine according to claim 1. Embodiments and improvements are defined in the dependent claims.
[0007] Die Erfindung wird im Folgenden anhand von Zeichnungen einer Messanordnung im Rundschalttisch näher erläutert. The invention will be explained in more detail below with reference to drawings of a measuring arrangement in the rotary indexing table.
Fig. 1 zeigt schematisch als ein Ausführungsbeispiel der Erfindung einen Schnitt durch eine Anlage mit einem Fig. 1 shows schematically as an embodiment of the invention a section through a system with a
Rundschalttisch mit einer Messanordnung und Fig. 2 zeigt den Grundriss der Anlage von Fig. 1. Rotary table with a measuring arrangement and Fig. 2 shows the outline of the system of Fig. 1st
[0008] In den Fig. 1 und 2 sind die Messeinrichtungen zum Erfassen der Positionsabweichungen zwischen den Werkstückachsen und den Werkzeugachsen schematisch dargestellt. In Figs. 1 and 2, the measuring means for detecting the positional deviations between the workpiece axes and the tool axes are shown schematically.
[0009] Der Rundschalttisch enthält ein mit dem Maschinenbett 1 fest verbundenes Unterteil 2. Die über ein Getriebe 3 angetriebene drehbare Schalttischplatte 4 ist in einer Hirthverzahnung 5 indexiert. Auf der Schalttischplatte 4 sind die Werkstück-Spindeleinheiten 6 mit je einem Werkstück 7 angeordnet. The rotary indexing table includes a fixedly connected to the machine bed 1 lower part 2. The driven via a gear 3 rotatable indexing table plate 4 is indexed in a Hirth gearing 5. On the indexing table plate 4, the workpiece spindle units 6 are each arranged with a workpiece 7.
[0010] Rund um die Schalttischplatte sind die Bearbeitungseinheiten mit Kreuzschlitten 8 und Werkzeug-Spindel-einheiten 9 mit je einem Werkzeug 10 angeordnet. Around the indexing table plate, the processing units with cross slide 8 and tool spindle units 9 are each arranged with a tool 10.
[0011] Die erfindungsgemässe Messanordnung enthält einen an der drehbaren Schalttischplatte befestigten inkremen-tellen Ringmassstab 11 oder mehrere inkrementelle Ringmassstäbe und auf dem festen Schalttischunterteil 2 befestigte, inkrementelle Leseköpfe 12. Jeder Bearbeitungsstation 9 ist ein Lesekopf 12 zugeordnet. Dadurch kann eine Streubreitenkorrektur durchgeführt werden, so dass jede Rundtaktstation mit der Genauigkeit einer linearen Station arbeiten kann. The measuring arrangement according to the invention comprises an incremental ring scale 11 attached to the rotatable indexing table top or a plurality of incremental ring standards and incremental read heads 12 mounted on the fixed indexing table bottom 2. Each processing station 9 is assigned a read head 12. Thereby, a spreading width correction can be performed so that each round-clock station can operate with the accuracy of a linear station.
[0012] Dabei kann allen Leseköpfen 12 ein einziger Ringmassstab 11 oder jedem Lesekopf 12 je ein Ringmassstab 11 zugeordnet sein. In einer Ausführungs Variante ist für jeden Lesekopf ein Ringmassstab-Segment vorgesehen, wobei jedes Segment mindestens einen Referenzpunkt aufweist. In this case, all read heads 12 a single ring scale 11 or each read head 12 may each be associated with a ring scale 11. In an embodiment variant, a ring scale segment is provided for each read head, each segment having at least one reference point.
[0013] Das Einrichten der Streubreitenkorrektur wird nach folgendem Ablauf durchgeführt: The setting of the spreading width correction is carried out according to the following sequence:
- In der Grundstellung der Schalttischplatte 4 werden die Positionszähler der Leseköpfe 12 auf Null gesetzt. - In the initial position of the control panel 4, the position counter of the read heads 12 are set to zero.
- In den folgenden Positionen werden die Werte der Positionszähler der Leseköpfe 12 als Referenzwerte gespeichert. In the following positions, the values of the position counters of the reading heads 12 are stored as reference values.
- Für die erste Bearbeitung wird die Schalttischplatte 4 in der Grundstellung positioniert. - For the first processing, the switch table plate 4 is positioned in the normal position.
- Die Istwerte der Positionszähler werden als Positionsabweichung ± X gespeichert. - The actual values of the position counters are stored as position deviation ± X.
- Die Bearbeitungen mit allen Bearbeitungsstationen 9 werden durchgeführt und die Positionen X der Bearbeitungsstationen 9 gespeichert. The machining operations with all processing stations 9 are carried out and the positions X of the processing stations 9 are stored.
- Die folgenden Bearbeitungstakte werden nach dem Ablaufschema wie in der Grundstellung durchgeführt, bis jede Werkstück-Spindeleinheit 6 alle Bearbeitungsstationen 9 passiert hat. Alle Positionen X der Bearbeitungsstationen 9 und die dazugehörigen Positionsabweichungen ± X der Werkstück-Spindeleinheiten 6 zur Referenzposition sind damit erfasst und die Maschine eingerichtet. - The following processing cycles are performed according to the flowchart as in the basic position until each workpiece spindle unit 6 has passed all processing stations 9. All positions X of the processing stations 9 and the associated position deviations ± X of the workpiece spindle units 6 to the reference position are thus detected and set up the machine.
[0014] Wie aus Obigem hervorgeht, gestattet die vorliegende Erfindung, die Positionsstreubreite für jede einzelne Arbeitsstation messtechnisch zu erfassen und als Korrekturwert der Steuerung zuzuführen. As is apparent from the above, the present invention allows to detect the position spread for each individual workstation by measurement and supply as a correction value of the control.
[0015] Damit können automatisch bei jeder Positionierung die X-Achsen der Bearbeitungsstationen auf die gegenüberliegenden Werkstück-Spindelachsen exakt ausgerichtet werden und damit eine Genauigkeit erzielt werden, die mindes- Thus, the X-axes of the processing stations can be aligned exactly to the opposite workpiece spindle axes automatically with each positioning and thus an accuracy can be achieved, the least
