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 Schleifen von Nuten und andern Vertiefungen, in welchem eine Lagerung für ein rotierendes Schleifwerkzeug und Antriebsteile zum Antrieb des Schleifwerkzeuges untergebracht sind, wobei der Schleifkopf an einem Tragteil befestigt ist, ein Verfahren zum Betrieb des Schleifkopfes und eine Maschine für denselben.The invention relates to a grinding head for grinding grooves and other recesses, in which a bearing for a rotating grinding tool and drive parts for driving the grinding tool are accommodated, the grinding head being fastened to a supporting part, a method for operating the grinding head and a machine for the same .

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

Weitere Nachteile der beiden Bearbeitungsverfahren sind in dem gleichzeitig hinterlegten Schutzrecht CH-PS ...... (BE 20 417) beschrieben und es wird auf dieses Schutzrecht ausdrücklich als Teil des vorliegenden Schutzrechtes Bezug genommen.Further disadvantages of the two processing methods are described in the protective right CH-PS ...... (BE 20 417), which is filed at the same time, and this protective right is expressly referred to as part of the present protective right.

Der Erfindung liegt die Aufgabe zugrunde, einen Schleifkopf der eingangs beschriebenen Art so auszugestalten, dass damit unter Vermeidung der Nachteile der bekannten Verfahren Nuten und Vertiefungen auch in engen Bohrungen exakt und kontinuierlich bearbeitet werden können.The object of the invention is to design a grinding head of the type described in the introduction in such a way that grooves and depressions can be machined precisely and continuously, even in narrow bores, while avoiding the disadvantages of the known methods.

Diese Aufgabe wird dadurch gelöst, dass der Schleifkopf als stabförmiger Hohlkörper ausgebildet ist, in welchem sowohl das Schleifwerkzeug an dem einen Ende mit quer zur Achse des Schleifkörpers liegender Drehachse als auch die sich gegen das andere, antriebseitige Ende des Schleifkopfes erstreckenden Antriebsteile gelagert sind.This object is achieved in that the grinding head is designed as a rod-shaped hollow body, in which both the grinding tool is mounted at one end with the axis of rotation lying transversely to the axis of the grinding body and also the drive parts extending towards the other end of the grinding head on the drive side.

Die Erfindung umfasst auch ein Verfahren zum Betrieb des erfindungsgemässen Schleifkopfes beim Schleifen von Nuten in Bohrungen, welche Aufgabe in optimaler Weise dadurch gelöst wird, dass in einer Aufspannung des Werkstückes zuerst die einen gegenüberliegenden Flanken zweier gegenüberliegender Nuten und in einer zweiten, um 180° gedrehten Aufspannung des Werkzeuges die beiden andern gegenüberliegenden Flanken dieser Nuten bearbeitet werden.The invention also encompasses a method for operating the grinding head according to the invention when grinding grooves in bores, which object is optimally achieved by first clamping the opposite flanks of two opposite grooves in a clamping of the workpiece and rotating them by 180 ° in a second Clamping of the tool, the two other opposite flanks of these grooves are machined.

Weiter umfasst die Erfindung auch eine Maschine, mit dem der Einsatz des Schleifkopfes in optimaler Weise gewährleistet wird. Diese Aufgabe wird dadurch gelöst, dass einerseits ein fester Träger als Werkzeugträger, an dem der Schleifkopf verschiebbar gelagert ist, und andererseits ein bezüglich des Abstandes zum festen Träger verstellbar geführter Träger als Arbeitstisch für das Werkstück vorgesehen ist.The invention also includes a machine with which the use of the grinding head is optimally guaranteed. This object is achieved in that on the one hand a fixed support as a tool support on which the grinding head is displaceably mounted, and on the other hand a support which is adjustable with respect to the distance from the fixed support is provided as a work table for the workpiece.

. Zweckmässig ist hierbei der Werkzeugträger ein mit den Enden von zwei vertikalen Säulen festverbundenes horizontales Joch, auf dem der Schleifkopf in Längsrichtung des Joches verschiebbar gelagert ist, und der Arbeitstisch an den beiden Säulen höhenverstellbar geführt ist, wobei der Arbeitstisch mit einem Einfach- oder einem Kreuzschlitzen und vorzugsweise mit einem Teilapparat ausgerüstet ist.. The tool carrier is expediently a horizontal yoke firmly connected to the ends of two vertical columns, on which the grinding head is mounted so as to be displaceable in the longitudinal direction of the yoke, and the work table on the two columns is adjustable in height, the work table having a single slot or a cross slot and is preferably equipped with a dividing head.

Der in Fig. 1 dargestellte Schleifkopf 1 weist an seinem freien Ende 2 ein Schleifwerkzeug 3 auf, dessen Drehachse 4 quer zur Längsachse 5 eines stabförmigen Körpers 6 des Schleifkopfes angeordnet ist. Der stabförmige Körper 6 weist an seinem antriebseitigen Ende 7 einen Befestigungsflansch 8 auf, an welchem ein Gehäuse 10 befestigt, z.B. angeschraubt, ist und einen Tragteil für den Schleifkopf 1 bildet. Im stabförmigen Körper 6 sind Antriebsteile für den Antrieb des Schleifkopfes 3 angebracht, die im einzelnen noch beschrieben werden. Im Gehäuse 10 sind weitere Antriebsteile untergebracht, die mit den Antriebsteilen des Schleifkopfes 1 zusammenwirken und den Anschluss an einen motorischen Antrieb in einer Bearbeitungsmaschine ermöglichen. Im Bereich des Befestigungsflansches 8, wo die Antriebsteile des Schleifkopfes 1 mit den weiteren Antriebsteilen des Gehäuses 10 verbunden sind, kann es erforderlich sein, eine Ausbuchtung 12 im stabförmigen Körper 6 vorzusehen. Dadurch wird jedoch die Eignung des stabförmigen Körpers, das Schleifwerkzeug 3 in enge Bohrungen einzuführen, praktisch nicht beeinträchtigt. Durch einen Kühlmittelanschluss 9 wird ein Kühlmedium in den Schleiffkopf 1 geführt, zwecks Kühlung des Werkzeuges und zum Entfernen der Späne.The grinding head 1 shown in Fig. 1 has at its free end 2 a grinding tool 3, the axis of rotation 4 is arranged transversely to the longitudinal axis 5 of a rod-shaped body 6 of the grinding head. The rod-shaped body 6 has at its drive end 7 a fastening flange 8, to which a housing 10 is fastened, for example screwed, and forms a supporting part for the grinding head 1. In the rod-shaped body 6 drive parts for driving the grinding head 3 are attached, which will be described in more detail. In the housing 10 further drive parts are accommodated, which cooperate with the drive parts of the grinding head 1 and enable connection to a motor drive in a processing machine. In the area of the fastening flange 8, where the drive parts of the grinding head 1 are connected to the further drive parts of the housing 10, it may be necessary to provide a bulge 12 in the rod-shaped body 6. However, this practically does not affect the suitability of the rod-shaped body for inserting the grinding tool 3 into narrow bores. A coolant is fed through a coolant connection 9 into the grinding head 1 for the purpose of cooling the tool and for removing the chips.

Auf dem dem Schleifkopf 1 abgewandten Ende des Gehäuses 10 ist ein Antriebskonus 11, z.B. ein Morsekonus, angeordnet, mit dem die Verbindung zu den maschinenseitigen Antriebsteilen bewerkstelligt wird.On the end of the housing 10 facing away from the grinding head 1 there is a drive cone 11, e.g. a Morse cone is arranged, with which the connection to the machine-side drive parts is accomplished.

Der in Fig. 2 dargestellte Schleifkopf 1 weist an seinem antriebseitigen Ende 7 einen Befestigungsflansch 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 im stabförmigen Körper 6 drehbar auf einer Antreibswelle 14 gelagerten Zahnkupplung 18 verbunden ist. Die Antriebswelle 14 erstreckt sich exzentrisch durch den stabförmigen Körper 6 und treibt eine Schleifwelle 19 mit dem Schleifwerkzeug 3, z.B. eine Schleifscheibe, über ein Schraubgetriebe 20 an, von dem in Fig. 2 das auf der 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. 2 has at its drive end 7 a fastening flange 8 which is integrally connected to a housing part 10. A high-frequency motor 13, for example with liquid circulation cooling, is mounted in the housing part 10 as a further drive part and has a toothed coupling 18 which is rotatably mounted on a drive shaft 14 in the rod-shaped body 6 connected is. The drive shaft 14 extends eccentrically through the rod-shaped body 6 and drives a grinding shaft 19 with the grinding tool 3, for example a grinding wheel, via a screw gear 20, of which the wheel 21 located on the drive shaft 14 is visible in FIG. 2, while the underlying wheel sitting on the grinding shaft 19 is not visible. The grinding shaft 19 is supported in bearings 22, 23, for example roller bearings, between which the grinding tool 3 is held by a drive ring 24. The bearing 22 is mounted in an arm 25 which is attached to the rod-shaped body 6 by means of a pin 26 and screws 27 on the rod-shaped body 6.

Fig. 2 zeigt weiter ein strichpunktiert dargestelltes Werkstück 30, in dessen Bohrung der Schleifkopf 1 eintaucht und Nuten 31 bearbeitet, wie dies anhand von Fig. 5 noch im Detail erläutert wird. In Fig. 3 sind einige, mit dem Schleifkopf nach Fig. 2 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. 2 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. 5. 3 shows some machining examples that can be carried out with the grinding head according to FIG. 2, these showing the grinding a) of a groove in a bore, b) of an outer rib, c) of a rectangular bore and d) of an outer recess.

In Fig. 4 ist der Anbau des Schleifkopfes 1 mit dem Schleifwerkzeug 3 und mit dem Gehäuse 10 an einer Fräsmaschine dargestellt. Der Antrieb kann hierbei gleich wie in Fig. 4 und 5 des erwähnten Parallelschutzrechtes ausgeführt sein, wobei der Antrieb von der Frässspindel der Fräsmaschine erfolgt. In Fig. 4 ist noch eine Lösung gezeigt, mit der höhere Drehzahlen erreicht werden können. Hierzu wird am Auslegerarm der Fräsmaschine ein Elektromotor 34 gelagert, der über einen Hülltrieb 35, z.B. einem Riementrieb, die Antriebswelle 14 des Schleifkopfes 1 antreibt. Dieses Einbaubeispiel zeigt, dass der Schleifkopf 1 eine grosse Anpassbarkeit an verschiedene Maschinen und Antriebe aufweist.4 shows the mounting of the grinding head 1 with the grinding tool 3 and with the housing 10 on a milling machine. The drive can be configured in the same way as in FIGS. 4 and 5 of the parallel protection law mentioned, the drive being carried out by the milling spindle of the milling machine. In Fig. 4 another solution is shown with which higher speeds can be achieved. For this purpose, an electric motor 34 is mounted on the cantilever arm of the milling machine, which drives the drive shaft 14 of the grinding head 1 via an enveloping drive 35, for example a belt drive. This installation example shows that the grinding head 1 is a has great adaptability to different machines and drives.

Das in Fig. 5 dargesrtellte, zu bearbeiten bestimmteThe one shown in Fig. 5 to be processed

Werkstück 30 weist eine Bohrung 36 auf, in welcher vier Nuten 37 (nur drei ersichtlich) mit einem Fräskopf nach Fig. 2 bearbeitet werden, bei dem in Fig. 5 freie Ende 2 von unten sichtbar ist. Aus Fig. 5 ist weiter ersichtlich, dass das Schleifwerkzeug 3, z.B. eine Schleifscheibe, nicht nur in Fig. 2 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 gegenüberliegener 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.Workpiece 30 has a bore 36 in which four grooves 37 (only three can be seen) are machined with a milling head according to FIG. 2, in which free end 2 is visible from below in FIG. 5. From Fig. 5 it can also be seen that the grinding tool 3, e.g. a grinding wheel, not only in Fig. 2 down, but also protrudes laterally from the cross section of the rod-shaped body 6. This results in the possibility of machining one opposing 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. 6 und 7 sind Schleifmaschinen beschrieben, die mit den beschriebenen Schleifköpfen 1 ausgerüstet sind. Der Einsatz solcher Maschinen kommt dann in Frage, wenn Nuten oder andere Vertiefungen bzw. Erhebungen in grösserem Umfang geschliffen werden müssen.6 and 7 grinding machines are described, which are equipped with the described grinding heads 1. 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. 6 weist die Schleifmaschine 45 ein auf einer Unterlage 46, z.B. einem Fundament, abgestütztes Maschinenbett 47 auf. Auf dem Maschinenbett 47 sind zwei senkrechte Säulen 48, 49 abgestützt, die an ihrem obern Ende mit einem horizontalen Träger 50 fest verbunden 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, z.B. wie in Fig. 2, 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 ausgebildet 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 58.6, the grinding machine 45 has a machine bed 47 supported on a base 46, for example a foundation. On the machine bed 47 are two lower right columns 48, 49 supported, which are fixedly connected at their upper end with a horizontal support 50. A grinding head 1 with a housing 10 is mounted on the carrier 50 on a horizontally displaceable slide 51. The housing 10 can expediently contain the motor drive, for example as in FIG. 2. A horizontal work table 52 is guided in height-adjustable manner in guides 53, 54 on the columns 48, 49. A cross slide 55 is attached to the work table 52 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 are 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 when the slide 51 is laterally movable with the grinding head 1. The workpiece mounted on the cross slide 55 and to be machined with the grinding head 1 is not shown for the sake of simplicity. A drive, for example a hydraulic drive, for the height adjustment of the work table 52 can be accommodated in the machine bed 47; A control cabinet 58 is used to control and regulate the drives used on the machine 45.

Die in Fig. 7 dargestellte Schleifmaschine 60 entspricht im wesentlichen der Schleifmaschine 45 nach Fig. 6, jedoch in liegender Anordnung. Dementsprechend ist der Arbeitstisch 61 nicht vertikal sondern horizontal beweglich und ebenso ist der Schleifkopf 1 mit dem Gehäuse 10 nicht senkrecht, sondern horizontal an einem vertikalen Träger 62 verschiebbar angeordnet. Die Verschiebemöglichkeiten sind durch ein Pfeilkreuz angedeutet. Das Werkstück 30 ist auf dem Arbeitstisch 61 entweder direkt oder auf einem querverschiebbaren Schlitten befestigt. Die Bewegungspfeile an dem Schleifkopf 1 sind die Bewegungsrichtungen des Arbeitstisches 61. Der ganze Arbeitsbereich der Schleifmaschine 60 ist mit einem Gehäuse 63 abgedeckt.The grinding machine 60 shown in FIG. 7 essentially corresponds to the grinding machine 45 according to FIG. 6, but in a lying arrangement. Accordingly, the work table 61 is not movable vertically but horizontally, and likewise the grinding head 1 with the housing 10 is not arranged vertically, but can be displaced horizontally on a vertical support 62. The options for moving are indicated by an arrow cross. The workpiece 30 is on the work table 61 either directly or on a cross-slide Carriage attached. The movement arrows on the grinding head 1 are the directions of movement of the work table 61. The entire working area of the grinding machine 60 is covered by a housing 63.

Mit den beiden beschriebenen Schleifmaschinen ist es möglich, den Schleifkopf 1 in optimaler Weise einzusetzen und mit einem Schleifkopf nach Fig. 2 die Bearbeitung von jeweils zwei gegenüberliegenden Nutenflanken in derselben Einstellung der Maschine durchzuführen.With the two grinding machines described, it is possible to use the grinding head 1 in an optimal manner and, with a grinding head according to FIG. 2, to process two opposite groove flanks in the same setting of the machine.

Als Schleifkopf 1 können auch die in dem erwähnten Parallelschutzrecht beschriebenen Fräsköpfe verwendet werden. Im Hinblick auf unterschiedliche Drehzahlen beim Fräsen und Schleifen können die Uebersetzungen der Antriebe, Antriebsteile und der weiteren Antriebsteile in dem Gehäuse 10 entsprechend angepasst werden.The milling heads described in the parallel protection law mentioned can also be used as the grinding head 1. With regard to different speeds during milling and grinding, the ratios of the drives, drive parts and further drive parts in the housing 10 can be adjusted accordingly.
