Abstract

The grinding head has a bar-like member, on whose free end is mounted a grinding tool with a grinding wheel spindle arranged at right angles to the longitudinal axis of the bar-like member. The grinding tool is driven by means of a work gear and a driving shaft, which is driven by means of a coupling with a motor. The motor is mounted in a casing, which is shaped onto the mounting flange. The grinding head can be vertically or horizontally arranged in the grinding or milling machine. Due to the fact that the grinding tool has a larger diameter than that of the bar-like member, facing groove sides in bores can be worked in one setting, so that the complete working operation is made faster due to the few idle strokes and simultaneously precision is increased.

Description

Die Erfindung betrifft einen Schleifkopf zum Bearbeiten von Nuten und andern Vertiefungen, in welchem eine Lagerung für ein rotierendes Schleifwerkzeug und Antriebsteile zum Antrieb des Schleifwerkzeugs untergebracht sind und welcher an einem Tragteil befestigt ist, wobei der Schleifkopf ein stabförmiger Körper ist, in welchem das den Körper an gegenüberliegenden Seiten überragende Schleifwerkzeug an dem einen Ende des Körpers gelagert ist sowie von dem andern, antriebseitigen Ende über ein Getriebe mit der das Schleifwerkzeug tragenden Welle verbunden ist, wobei der Schleifkopf mit einem, ein Gehäuse aufweisenden Befestigungsflansch zu Aufnahme der Antriebswelle des Schleifkopfes verbunden ist.The invention relates to a grinding head for machining grooves and other recesses, in which a bearing for a rotating grinding tool and drive parts for driving the grinding tool are accommodated and which is fastened to a supporting part, the grinding head being a rod-shaped body in which the body Grinding tool projecting on opposite sides is mounted on one end of the body and is connected from the other, drive-side end via a gear to the shaft carrying the grinding tool, the grinding head being connected to a mounting flange having a housing for receiving the drive shaft of the grinding head .

Zum Bearbeiten von Nuten und andern Vertiefungen werden vor allem das Räumen und das Stossen derselben verwandet, Beiden Verfahren sind verhältnismässig enge Grenzen gesetzt, da Werkstücke aus hochfestem Material oder gar gehärtetem Material nicht damit bearbeitet werden können.For machining grooves and other recesses, broaching and pounding are mainly used, both methods are relatively narrow limits, since workpieces made of high-strength material or even hardened material cannot be processed with it.

Aus DE-A-2 552 259 ist ein Schleifkopf bekannt, bei dem das Schleifwerkzeug innerhalb des Querschnittes eines stabförmigen Körpers auf einer Welle gelagert ist. Diese Welle wird durch einen Riementrieb angetrieben, der sich längs eines stabförmigen Körpers bis zu dem dem Schleifwerkzeug gegenüberliegenden Antriebsende erstreckt. Die Benetzung des Riemens durch die Schleifflüssigkeit ist unvermeidlich, weshalb dadurch die Lebensdauer des Riemens vermindert wird. Um dieser Benetzung des Riemens entgegenzuwirken, ist vorgesehen, dass die Lagerung des Schleifwerkzeuges und der Riemen durch ein Übergeschobenes Abdeckrohr und eine Abdeckhülse völlig abgekapselt wird. Dies bedeutet einen erheblichen zusätzlichen Aufwand, der auch Dichtungsprobleme beim Gebrauch mit sich bringt.From DE-A-2 552 259 a grinding head is known in which the grinding tool is mounted on a shaft within the cross section of a rod-shaped body. This shaft is driven by a belt drive, which extends along a rod-shaped body to the drive end opposite the grinding tool. Wetting the belt with the grinding fluid is unavoidable, which reduces the belt life. To counteract this wetting of the belt, it is provided that the mounting of the grinding tool and the belt is completely encapsulated by a cover tube and a cover sleeve. This means a considerable additional effort, which also brings sealing problems with use.

Der Erfindung liegt die Aufgabe zugrunde, einen Schleifkopf der eingangs beschriebenen Art so auszugestalten, dass damit unter Vermeidung der Nachteile der bekannten Schleifköpfe und Vertiefungen auch in engen Bohrungen exakt bearbeitet werden können.The invention has for its object to design a grinding head of the type described in such a way that it can be machined precisely in narrow bores while avoiding the disadvantages of the known grinding heads and recesses.

Diese Aufgabe wird dadurch gelöst, dass als Antriebsteil ein Hochfrequenzmotor vorgesehen ist, der mit einer Längswelle gekuppelt ist, welche sich durch den stabförmigen Körper in einer zur Längsachse desselben parallelen, exzentrischen Längsbohrung erstreckt und über ein Zahnradgetriebe mit Schraubenrädern mit der Welle des Schleifwerkzeuges verbunden ist, und das von den beidseits des Schleifwerkzeugs angeordneten, die Welle des Schleifwerkzeugs abstützenden Lager das von dem Zahnradgetriebe entferntere lager in einem am stabförmigen Körper fest angeordneten Arm aufgenommen ist.This object is achieved in that a high-frequency motor is provided as the drive part, which is coupled to a longitudinal shaft which extends through the rod-shaped body in an eccentric longitudinal bore parallel to the longitudinal axis thereof and is connected to the shaft of the grinding tool via a gear transmission with helical wheels , and the bearing, which is arranged on both sides of the grinding tool and supports the shaft of the grinding tool, accommodates the bearing which is more distant from the gear transmission in an arm which is fixedly arranged on the rod-shaped body.

Weiter umfasst die Erfindung auch eine Maschine, mit dem der Einsatz des Schleifkopfes in optimaler Weise gewährleistet wird. Diese Aufgabe wird dadurch gelöst, dass ein ortsfester Träger ein mit den Enden von zwei vertikalen Säulen fest verbundenes, horizontales Joch ist, auf dem der Schleifkopf in Längsrichtung des Joches verschiebbar gelagert ist, wobei ein bezüglich des Abstandes zum ortsfesten Träger an den Säulen höhenverstellbargeführterTräger als Arbeitstisch für das Werkstück ausgebildet ist, welcher mit einem Einfach- oder einem Kreuzschlitten und vorzugsweise mit einem Teilapparat ausgerüstet ist.The invention also includes a machine with which the use of the grinding head is optimally guaranteed. This object is achieved in that a stationary support is a horizontal yoke which is firmly connected to the ends of two vertical columns and on which the grinding head is mounted so as to be displaceable in the longitudinal direction of the yoke, with a support which is adjustable in height on the columns with respect to the distance from the stationary support Working table is formed for the workpiece, which is equipped with a single or a cross slide and preferably with a dividing head.

Der in Fig. 1 dargestellte Schleifkopf 1 weist an seinem antriebsseitigen Ende 7 einen Befestigungsflanch 8 auf, der integral mit einem Gehäuseteil 10 verbunden ist. Im Gehäuseteil 10 ist als weiterer Antriebsteil ein Hochfrequenzmotor 13, z.B. mit einer Flüssigkeits-Umlaufkühlung, gelagert, der mit einer in einem stabförmigen Körper 6 drehbar auf einer Antriebswelle 14 gelagerten Zahnkupplung 18 verbunden ist. Die Antriebswelle 14 erstreckt sich exzentrisch durch den stabförmigen Körper 6 und treibt eine Schleifwelle 19 mit einem Schleifwerkzeug 3, z.B. eine Schleifscheibe, überein Schraubgetriebe 20 an, von dem in Fig. 1 das aufder Antriebswelle 14 befindliche Rad 21 sichtbar ist, während das auf der Schleifwelle 19 sitzende darunterliegende Rad nicht sichtbar ist. Die Schleifwelle 19 ist in Lagern 22, 23, z.B. Wälzlagern, gelagert zwischen denen das Schleifwerkzeug 3 durch einen Mitnehmerring 24 gehalten ist, das Lager 22 ist in einem Arm 25 gelagert, der am stabförmigen Körper 6 mittels eines Stiftes 26 und Schrauben 27 am stabförmigen Körper 6 befestigt ist.The grinding head 1 shown in FIG. 1 has at its drive end 7 a fastening flange 8 which is integrally connected to a housing part 10. A high frequency motor 13, e.g. with a liquid circulation cooling, which is connected to a toothed coupling 18 rotatably mounted in a rod-shaped body 6 on a drive shaft 14. The drive shaft 14 extends eccentrically through the rod-shaped body 6 and drives a grinding shaft 19 with a grinding tool 3, e.g. a grinding wheel, via a screw gear 20, of which the wheel 21 located on the drive shaft 14 is visible in FIG. 1, while the underlying wheel sitting on the grinding shaft 19 is not visible. The grinding shaft 19 is in bearings 22, 23, e.g. Rolling bearings, between which the grinding tool 3 is held by a driving ring 24, the bearing 22 is mounted in an arm 25 which is fastened to the rod-shaped body 6 by means of a pin 26 and screws 27 on the rod-shaped body 6.

Fig. 1 zeigt weiter ein strichpunktiert dargestelltes Werkstück 30, in dessen Bohrung der Schleifkopf 1 eintaucht und Nuten 31 bearbeitet, wie dies anhand von Fig. 3 noch im Detail erläutert wird. In Fig. 2 sind einige, mit dem Schleifkopf nach Fig. 1 ausführbare Bearbeitungsbeispiele dargestellt, wobei diese das Schleifen a) einer Nut in einer Bohrung, b) einer Aussenrippe, c) einer Rechteckbohrung und d) einer Aussenvertiefung zeigen.FIG. 1 also shows a workpiece 30 shown in broken lines, in the bore of which the grinding head 1 is immersed and machined grooves 31, as will be explained in detail with reference to FIG. 3. In Fig. 2 are some that can be carried out with the grinding head according to Fig. 1 Machining examples shown, which show the grinding a) a groove in a hole, b) an outer rib, c) a rectangular hole and d) an outer recess.

Das in Fig. 3 dargestellte, zu bearbeiten bestimmte Werkstück 30 weist eine Bohrung 36 auf, in welcher vier Nuten 37 (nur drei ersichtlich) mit einem Fräskopf nach Fig. 1 bearbeitet werden, bei dem in Fig. 3 das freie Ende 2 von unten sichtbar ist. Aus Fig. 3 ist weiter ersichtlich, dass das Schleifwerkzeug 3, z.B. eine Schleifscheibe, nicht nur in Fig. 1 nach unten, sondern auch seitlich aus dem Querschnitt des stabförmigen Körpers 6 ragt. Damit ergibt sich die Möglichkeit, je eine gegenüberliegende Flanke 38, 39 zweier gegenüberliegender Nuten 37 in derselben Aufspannung zu bearbeiten, wobei lediglich eine Verschiebung des das Werkstück 30 tragenden Schlittens oder des Schleifkopfes 1 erforderlich ist. Sind die Flanken 38, 39 bearbeitet, wird das Werkstück um 180° gedreht, worauf nun die gegenüberliegenden Flanken 40, 41 in einer Aufspannung bearbeitet werden. Durch die Ausbildung des Schleifkopfes nach Fig. 2 wird eine äusserst genaue Bearbeitung von Nutenflanken mit einer geringen Zahl Leerbewegungen erreicht.The workpiece 30 shown in FIG. 3 to be machined has a bore 36 in which four grooves 37 (only three can be seen) are machined with a milling head according to FIG. 1, in which in FIG. 3 the free end 2 from below is visible. From Fig. 3 it can also be seen that the grinding tool 3, e.g. a grinding wheel, not only in Fig. 1 down, but also protrudes laterally from the cross section of the rod-shaped body 6. This results in the possibility of machining an opposite flank 38, 39 of two opposing grooves 37 in the same clamping, only a displacement of the slide carrying the workpiece 30 or the grinding head 1 being necessary. Once the flanks 38, 39 have been machined, the workpiece is rotated through 180 °, whereupon the opposite flanks 40, 41 are machined in one setting. 2, extremely precise machining of groove flanks with a small number of empty movements is achieved.

In Fig. 4 ist eine Schleifmaschine beschrieben, die mit dem beschriebenen Schleifkopf 1 ausgerüstet ist. Der Einsatz solcher Maschinen kommt dann in Frage, wenn Nuten oder andere Vertiefungen bzw. Erhebungen in grösserem Umfang geschliffen werden müssen.4, a grinding machine is described, which is equipped with the grinding head 1 described. The use of such machines comes into question when grooves or other depressions or elevations have to be ground to a large extent.

In Fig. 4 weist die Schleifmaschine 45 ein aufeiner Unterlage 46, z.B, einem Fundament abgesetztes Maschinenbett 47 auf. Auf dem Maschinenbett 47 sind zwei senkrechte Säulen 48,49 abgestützt, die an ihrem obern Ende mit einem horizontalen Träger 50 festverbunden sind, Auf dem Träger 50 ist ein Schleifkopf 1 mit einem Gehäuse 10 auf einem horizontal verschiebbaren Schlitten 51 gelagert, Das Gehäuse 10 kann hierbei zweckmässig den motorischen Antrieb, wie in Fig. 1, enthalten. An den Säulen 48, 49 ist ein horizontaler Arbeitstisch 52 in Führungen 53, 54 höhenverstellbar geführt. Auf dem Arbeitstisch 52 ist ein Kreuzschlitten 55 mit einem Teilapparat 56 befestigt, mit dem die durch Pfeile angedeuteten Bewegungen ausgeführt werden können. Die Höhenverstellbarkeit des Arbeitstisches 52 und die Seitenverstellbarkeit des Schlittens 51 sind ebenfalls durch Pfeile angegeben und als handbetätigte Verstellantriebe dargestellt. Der Kreuzschlitten 55 kann auch als Einfachschlitten ausgebilet sein, da er bei vorhandener Seitenbeweglichkeit des Schlittens 51 mit dem Schleifkopf 1 nur in einer Richtung bewegt werden muss. Das auf dem Kreuzschlitten 55 gelagerte und mit dem Schleifkopf 1 zu bearbeitende Werkstück ist der Einfachheit halber nicht dargestellt. Im Maschinenbett 47 kann ein Antrieb, z.B. ein Hydroantrieb, für die Höhenverstellung des Arbeitstisches 52 untergebracht sein; zur Steuerung und Regelung der an der Maschine 45 eingesetzten Antriebe dient ein Schaltschrank 58.In Fig. 4, the grinding machine 45 has a machine bed 47 placed on a base 46, e.g., on a foundation. On the machine bed 47, two vertical columns 48, 49 are supported, which are firmly connected at their upper end to a horizontal support 50. On the support 50, a grinding head 1 with a housing 10 is mounted on a horizontally displaceable slide 51, the housing 10 can expediently contain the motor drive, as in FIG. 1. A horizontal work table 52 is guided in height-adjustable manner in guides 53, 54 on the columns 48, 49. On the work table 52, a cross slide 55 is fastened with a dividing device 56 with which the movements indicated by arrows can be carried out. The height adjustability of the work table 52 and the lateral adjustability of the slide 51 are also indicated by arrows and shown as manually operated adjustment drives. The cross slide 55 can also be designed as a single slide, since it only has to be moved in one direction with the grinding head 1 when the slide 51 is laterally movable. The workpiece mounted on the cross slide 55 and to be processed with the grinding head 1 is not shown for the sake of simplicity. A drive, e.g. a hydraulic drive, for the height adjustment of the work table 52; A control cabinet 58 is used to control and regulate the drives used on the machine 45.

Mit der beschriebenen Schleifmaschine ist es möglich, den Schleifkopf 1 in optimaler Weise einzusetzen und mit dem Schleifkopf nach Fig. 1 die Bearbeitung von jeweils zwei gegenüberliegenden Nutenflnaken in derselben Einstellung der Maschine durchzuführen.With the described grinding machine, it is possible to use the grinding head 1 in an optimal manner and, with the grinding head according to FIG. 1, to process two opposite slot flanks in the same setting of the machine.

Der Schleifkopf 1 kann auch als Fräskopf verwendet wreden. Im Hinblich auf die unterschiedlichen Drehzahlen beim Fräsen und Schleifen sind dann die Uebersetzungen der Antriebe, Antriebsteile und der weiteren Antriebsteile in dem Gehäuse 10 entsprechend anzupassen.The grinding head 1 can also be used as a milling head. The gear ratios of the drives, drive parts and the other drive parts in the housing 10 must then be adjusted accordingly with regard to the different speeds during milling and grinding.
