Eine Vorrichtung der eingangs bezeichneten Art wird unter Verwendung eines rotierenden Abrichtwerkzeuges vorwiegend eingesetzt zum Abrichten von Schleifscheiben mit einem Durchmesser in einer Größenordnung von etwa 200 bis 500 mm in Verbindung mit dem CD-Abrichtverfahren (continuous dressing) oder dem IPD-Abrichtverfahren (in-process-dressing), wobei das Abrichten intervallmäßig zum Beispiel während bestimmter Phasen des Schleifprozesses erfolgt (z.B. Grobabrichten während der Werkstücktisch-Fortschaltung oder während des Werkstückwechsels, Feinabrichten während des Schlichtschleifens).A device of the type described in the introduction is used using a rotating Dressing tool mainly used for dressing grinding wheels with a diameter on the order of about 200 to 500 mm in Connection with the CD dressing process (continuous dressing) or the IPD dressing process (in-process dressing), with dressing at intervals For example, during certain phases of the grinding process (e.g. rough dressing during the workpiece table advance or during the workpiece change, Fine dressing during finish grinding).

In der Praxis eingesetzte Abrichtgeräte sind aufgrund ihrer separaten linearen Zustellachsen, den zugeordneten Achsantrieben, Meßsystemen und Gehäusen relativ aufwendig und unwirtschaftlich. Dressers used in practice are due to their separate linear infeed axes, the assigned axis drives, measuring systems and housings relative complex and uneconomical.

Der Erfindung liegt die Aufgabe zugrunde, eine vereinfachte, wirtschaftlich betreibbare Abrichtvorrichtung zu schaffen.The invention has for its object a simplified, economically operable To create a dressing device.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass die Abrichtrollen an einem gemeinsamen Rollenträger gelagert sind, der um eine Achse schwenkend die Abrichtrollen wechselweise in eine der jeweils aktiven Schleifscheibe zugeordnete Abrichtposition zustellend angeordnet ist.
Gemäß zweckmäßigen Ausgestaltungen verläuft die Schwenkachse des Rollenträgers parallel zur Schleifspindelachse, wobei die Abrichtrollen parallel zur zentralen Schwenkachse um 1800 versetzt zueinander am Rollenträger gelagert sind. Vorzugsweise sind die Schleifscheiben achsgleich auf einer gemeinsamen Schleifspindel angeordnet.
Weiterhin wird vorgeschlagen, den Rollenträger mit seiner parallel zur Schleifspindelachse verlaufenden Schwenkachse über den vertikal verfahrbaren Schleifspindelträger anzuordnen.
Es ist außerdem von Vorteil, wenn die Schwenkachse des Rollenträgers als CNC-Schwenkachse ausgebildet ist, wobei der Schwenkantrieb des Rollenträgers als NC-Teilapparat ausgebildet ist, so dass eine kompakte, hochpräzise und spielfrei arbeitende Einheit erhalten wird, deren hohe Steifigkeit für die Übertragung eines hohen Drehmomentes geeignet ist.
Eine stabile Lagerung und ein leichtes und schnelles Auswechseln der Abrichtrollen ist nach einem weiteren Vorschlag dadurch gewährleistet, dass die Abrichtrollen tragende Rollendorne zweiseitig in einem Getriebegehäuse und in abziehbaren Gegenlagern gelagert sind.
Zum Zweck einer optimierten, gedrängten Bauweise ist eine gemeinsame Rollenantriebsachse durch die Teilapparatachse hindurchgeführt (Hohlwellenprinzip).This object is achieved according to the invention in that the dressing rollers are mounted on a common roller carrier, which is arranged so that the dressing rollers alternately feed into a dressing position assigned to the respectively active grinding wheel, pivoting about an axis.
According to expedient refinements, the swivel axis of the roller carrier runs parallel to the grinding spindle axis, the dressing rollers being mounted parallel to the central swivel axis by 1800 on the roller carrier. The grinding wheels are preferably arranged axially on a common grinding spindle.
Furthermore, it is proposed to arrange the roller carrier with its pivot axis running parallel to the grinding spindle axis above the vertically movable grinding spindle carrier.
It is also advantageous if the swivel axis of the roller carrier is designed as a CNC swivel axis, the swivel drive of the roller carrier being designed as an NC dividing device, so that a compact, highly precise and play-free unit is obtained, the high rigidity of which for the transmission of a high torque is suitable.
According to a further proposal, stable storage and easy and quick replacement of the dressing rollers is ensured by the fact that the roller mandrels carrying the dressing rollers are mounted on two sides in a gear housing and in removable counter bearings.
For the purpose of an optimized, compact design, a common roller drive axis is led through the dividing head axis (hollow shaft principle).

Die mit der Erfindung erzielten Vorteile bestehen in einer deutlichen Gewichtsersparnis und damit verbundenen reduzierten Dimensionierung der Maschinenkomponenten. Zudem kann der Aufwand für die Maschinensteuerung geringer gehalten werden. Außerdem ist aufgrund des reduzierten Schleifscheibenverbrauchs eine wirtschaftliche Betriebsweise gegeben, was wiederum die Stückkosten der zu schleifenden Teile reduziert. The advantages achieved by the invention are significant weight savings and the associated reduced dimensioning of the machine components. In addition, the effort for machine control can be reduced being held. In addition, due to the reduced grinding wheel consumption given an economical mode of operation, which in turn increases unit costs of the parts to be ground.

Die Erfindung wird nachstehend anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert.The invention is described below with reference to an embodiment shown in the drawing explained in more detail.

Figures 2 to 4
different working positions of the dressing device relative to the assigned grinding wheels.

Ein Schleifkopf 1 bestehend aus zwei auf einer gemeinsamen Schleifspindel 2 montierten Satzschleifscheiben 3, 4 ist mit seinem Schleifspindelträger 6 vertikal an einer Maschinensäule 7 verfahrbar.
Auf dem Schleifspindelträger 6 ist ein Abrichtgerät 8 installiert, welches zwei den Satzschleifscheiben 3, 4 umfangsseitig zugeordnete Abrichtrollen 9 und 11 aufweist, die auf Rollendornen 12 bzw. 13 montiert sind. Die Rollendorne 12, 13 sind einerseits antriebsseitig in einem Getriebegehäuse 14 und andererseits in abnehmbaren bzw.schnell wechselbaren Gegenlagern 16 bzw. 17 gelagert. Alle genannten Elemente sind als kompakte Einheit an einer Plattform 18 befestigt, so dass ein Rollenträger 19 erhalten wird, der um eine für die Abrichtrollen gemeinsame zentrale CNC-Achse 21 schwenkbar ist, welche parallel zur Schleifspindelachse 22 verläuft und zu der die Abrichtrollendorne 12, 13 mit den Abrichtrollen 9 und 11 parallel und um 180° versetzt zueinander gelagert sind und die darüber hinaus eine Gegenlagerstelle zur Aufnahme von Kräften in die Schleifscheibenschutzhaube bildet.
Der Schwenkantrieb des Rollenträgers 19 ist als NC-Teilapparat 22, beispielsweise vom Typ EA-430 der Firma Peter Lehmann, Schweiz mit zugeordnetem direktem inkrementalem Meßsystem 23 ausgebildet.
Eine für beide Abrichtrollen 9, 11 gemeinsame Antriebswelle 24 ist durch die als Hohlwelle ausgebildete Achse des Teilapparats 22 zu einem Getriebekasten 26 hindurchgeführt, an den ein Antriebsmotor 27 für die Abrichtrollen 9, 11 angeflanscht ist.
Mit 28 ist ein Servomotor für den NC-Rundtisch der Schleifmaschine bezeichnet.A grinding head 1 consisting of two set grinding wheels 3, 4 mounted on a common grinding spindle 2 can be moved vertically on a machine column 7 with its grinding spindle carrier 6.
On the grinding spindle carrier 6, a dressing device 8 is installed, which has two dressing rollers 9 and 11, which are assigned to the peripheral grinding wheels 3, 4 and are mounted on roller mandrels 12 and 13, respectively. The roller mandrels 12, 13 are mounted on the drive side in a gear housing 14 and on the other hand in removable or quickly exchangeable counter bearings 16 and 17. All of the elements mentioned are attached as a compact unit to a platform 18, so that a roller carrier 19 is obtained which can be pivoted about a central CNC axis 21 common to the dressing rollers, which runs parallel to the grinding spindle axis 22 and to which the dressing roller mandrels 12, 13 with the dressing rollers 9 and 11 parallel and offset by 180 ° to each other and which also forms a counter bearing for absorbing forces in the grinding wheel guard.
The swivel drive of the roller carrier 19 is designed as an NC dividing device 22, for example of the type EA-430 from Peter Lehmann, Switzerland, with an associated direct incremental measuring system 23.
A drive shaft 24 common to both dressing rollers 9, 11 is guided through the axis of the sub-apparatus 22, which is designed as a hollow shaft, to a gearbox 26 to which a drive motor 27 for the dressing rollers 9, 11 is flanged.
With 28 a servo motor for the NC rotary table of the grinding machine is designated.

In der in Figur 2 dargestellten neutralen Arbeitsstellung verläuft die Plattform 18 des Rollenträgers 19 horizontal ohne Eingriff der Abrichtrollen 9, 11 mit den zugeordneten Schleifscheiben 3 bzw. 4.
Gemäß Figur 3 ist der Rollenträger 19 um die Achse 21 in eine Abrichtposition 29 verschwenkt, in der die Abrichtrolle 11 die gerade aktive bzw. mit einem nicht dargestellten Werkstück im Eingriff befindliche Schleifscheibe 4 kontaktiert, während die andere Schleifscheibe 3 unbeaufschlagt bleibt.
Gemäß Figur 4 nimmt der Rollenträger 19 in einer entgegengesetzten Schwenkstellung eine Abrichtposition 31 ein, in der die Abrichtrolle 9 die gerade aktive Schleifscheibe 3 abrichtet, während die andere Abrichtrolle 11 von der Schleifscheibe 4 abgehoben ist.
Das wechselweise Abrichten der Schleifscheiben 9, 11 kann jeweils auch intervallmäßig in einem Zwischenstadium zwischen zwei Schleifzyklen erfolgen.
Auf diese Weise wird ein unnötiges Abrichten vermieden und der Schleifscheibenverbrauch um gut 50° reduziert.In the neutral working position shown in FIG. 2, the platform 18 of the roller carrier 19 runs horizontally without engagement of the dressing rollers 9, 11 with the associated grinding wheels 3 and 4.
According to FIG. 3, the roller carrier 19 is pivoted about the axis 21 into a dressing position 29, in which the dressing roller 11 contacts the grinding wheel 4 which is currently active or which is in engagement with a workpiece, not shown, while the other grinding wheel 3 remains unloaded.
According to FIG. 4, the roller carrier 19 takes up a dressing position 31 in an opposite pivoting position, in which the dressing roller 9 trains the currently active grinding wheel 3, while the other dressing roller 11 is lifted off the grinding wheel 4.
The alternate dressing of the grinding wheels 9, 11 can also take place at intervals in an intermediate stage between two grinding cycles.
In this way, unnecessary dressing is avoided and grinding wheel consumption is reduced by a good 50 °.
