Abstract

The grinding apparatus has a clamping device (10) with clamping jaws (12, 14) between which a handle (16) can be clamped in such a way that the position of a centre plane (A) of the handle (16) normal to the handle ends (18, 18') is fixed and the handle ends (18, 18') are accessible for grinding. A grinding unit (30, 30') is allocated to each of the handle ends (18, 18'). The grinding units (30, 30') have a bearing block (32 or 32') which defines a rotary axis (D, D') of a rotationally drivable grinding body (40, 40') and can be positioned and moved in a reciprocating manner with regard to the clamping device (10). The rotary axes (D, D') of both grinding bodies (40, 40') lie in the centre plane (A), and the bearing blocks (32, 32') can each be pivotably adjusted about a separate pivot axis (C, C') at least approximately normal to the centre plane (A). <IMAGE>

Description

Die Erfindung betrifft eine Schleifmaschine zum Vorbereiten der Enden eines keramischen Henkels für das Angarnieren an einen Gefäßkörper, mit einer Einspannvorrichtung für den Henkel.The invention relates to a grinding machine for preparing the ends of a ceramic handle for garnishing to a vessel body, with a clamping device for the handle.

Gemäß der DL-PS 99325 werden Henkel paarweise gegossen, anschließend weißgetrocknet und entgratet. Sodann werden die Henkelpaare geglüht und im geglühten Zustand in einer Schneidvorrichtung, bestehend aus vier verstellbar angeordneten Trennschleifscheiben, zugeschnitten. Schließlich werden in einer Schleifmaschine Ansatzflächen an den Henkelenden durch einen rotierenden Schleifkörper an das Außenprofil von Tassen angepaßt, an welche die Henkel angarniert werden sollen. Dabei ist es erforderlich, daß der Schleifkörper ein zum Außenprofil der Tassen komplementäres Profil aufweist. Ein solcher Schleifkörper ist teuer in seiner Herstellung und muß häufig abgerichtet werden, damit er das vorgegebene Profil beibehält. Ändert sich die Form der Tassen, an welche die Henkel angarniert werden sollen, so muß ein entsprechend geänderter Schleifkörper in die bekannte Schleifmaschine eingesetzt werden.According to DL-PS 99325, handles are cast in pairs, then dried in white and deburred. The pairs of handles are then annealed and cut in the annealed state in a cutting device consisting of four adjustable cutting wheels. Finally, in a grinding machine, attachment surfaces on the ends of the handles are adapted by a rotating grinding body to the outer profile of cups to which the handles are to be attached. It is necessary that the grinding wheel has a profile complementary to the outer profile of the cups. Such a grinding wheel is expensive to manufacture and often has to be dressed in order to maintain the specified profile. If the shape of the cups to which the handles are to be attached changes, a correspondingly modified grinding wheel must be inserted into the known grinding machine.

Der Erfindung liegt die Aufgabe zugrunde, eine Schleifmaschine der genannten Gattung derart weiterzubilden, daß sie zum Bearbeiten von an unterschiedliche Profile von Gefäßkörpern angepaßten Henkeln mit geringerem Aufwand umrüstbar ist.The invention has for its object to develop a grinding machine of the type mentioned in such a way that it can be converted with less effort for processing handles adapted to different profiles of vessel bodies.

Die Aufgabe ist erfindungsgemäß dadurch gelöst, daß die Schleifmaschine zwei voneinander getrennte, gegen die Einspannvorrichtung zustellbare Schleifaggregate aufweist, mit denen die beiden Henkelenden gleichzeitig geschliffen werden können, und daß die Schleifaggregate von Lagerböcken getragen sind, die um je eine eigene, zur zu den Henkelenden normalen Mittelebene des Henkels mindestens annähernd normale Schwenkachse schwenkeinstellbar sind.The object is achieved in that the grinding machine has two separate, against the clamping device adjustable grinding units with which the two handle ends can be ground at the same time, and that the grinding units are supported by pedestals, each with its own, to the handle ends normal center plane of the handle are at least approximately normal pivot axis adjustable.

Damit wird erreicht, daß unabhängig von der Form der Gefäßkörper, an welche die geschliffenen Henkel angarniert werden sollen, stets im wesentlichen gleiche Schleifkörper verwendet werden können. Die Schleifkörper der Maschine können entweder unmittelbar schleifend auf die Henkelenden einwirken oder von je einem Schleifband bekannter Art umschlungen werden.This ensures that, regardless of the shape of the vessel body to which the ground handles are to be attached, essentially the same grinding body can always be used. The grinding wheels of the machine can either have a direct grinding action on the ends of the handles or can be wrapped around by a grinding belt of known type.

Es ist zweckmäßig, wenn die Schleifkörper die Form von balligen Rollen aufweisen.It is expedient if the grinding wheels have the shape of spherical rollers.

Es ist ferner zweckmäßig, wenn die Lagerböcke beider Schleifaggregate an einem gemeinsamen Schlitten befestigt sind, der in Richtung zur Einspannvorrichtung zustellbar ist.It is also expedient if the bearing blocks of both grinding units are fastened to a common slide which can be advanced in the direction of the clamping device.

Dabei ist es vorteilhaft, wenn dem Schlitten eine Dämpfungsvorrichtung zugeordnet ist, die bei Annäherung der Schleifkörper an die Einspannvorrichtung die Zustellgeschwindigkeit mindert.It is advantageous if a damping device is assigned to the slide, which reduces the infeed speed when the grinding bodies approach the clamping device.

Die erfindungsgemäße Schleifmaschine kann ferner dadurch weitergebildet sein, daß an jedem Lagerbock ein um die Achse des zugehörigen Schleifkörpers schwenkeinstellbarer Tragkörper befestigt ist, und die Schleifkörper über je einen Riementrieb von je einem eigenen Motor angetrieben sind, der am zugehörigen Tragkörper über eine Spannvorrichtung abgestützt ist. Damit wird erreicht, daß die Motoren in einem Bereich angeordnet werden können, in dem sie nicht stören, und die Tragkörper so eingestellt werden können, daß sie auch dann nicht miteinander kollidieren, wenn die Schleifkörper in eine Stellung in bezug zueinander gebracht werden müssen, die ein Beschleifen von Henkeln für Gefäßkörper mit konkaver Außenkontur ermöglicht.The grinding machine according to the invention can also be further developed in that a supporting body which can be pivoted about the axis of the associated grinding body is fastened to each bearing block, and the grinding bodies are each driven by a separate motor via a belt drive, which is attached to the associated supporting body via a tensioning device is supported. This ensures that the motors can be arranged in an area in which they do not interfere, and the support body can be adjusted so that they do not collide with each other even if the grinding body must be brought into a position with respect to each other Grinding of handles for vessel bodies with a concave outer contour enables.

Schließlich ist es im allgemeinen vorteilhaft, wenn die Achsen beider Schleifkörper der Maschine in der Mittelebene des Henkels liegen.Finally, it is generally advantageous if the axes of both grinding bodies of the machine lie in the central plane of the handle.

Die dargestellte Schleifmaschine hat eine Einspannvorrichtung 10 mit zwei übereinander angeordneten Spannbacken 12 und 14, zwischen denen ein Henkel 16 einspannbar ist, dessen Henkelenden 18 und 18' beschliffen werden sollen. Der Henkel 16 ist symmetrisch in bezug auf eine Mittelebene A, die der Formteilungsebene einer Gießform entspricht, in welcher der Henkel 16, ggf. mit weiteren gleichen Henkeln, gegossen worden ist. Im dargestellten Beispiel liegt die Mittelebene A waagerecht. Die Einspannvorrichtung 10 kann zusammen mit mehreren gleichen Einspannvorrichtungen an einem Förderer angeordnet sein, beispielsweise an einem Drehtisch.The grinding machine shown has a clamping device 10 with two clamping jaws 12 and 14 arranged one above the other, between which a handle 16 can be clamped, the handle ends 18 and 18 'of which are to be ground. The handle 16 is symmetrical with respect to a central plane A, which corresponds to the mold division plane of a casting mold in which the handle 16, possibly with other identical handles, has been cast. In the example shown, the central plane A is horizontal. The clamping device 10 can be arranged together with several identical clamping devices on a conveyor, for example on a turntable.

Die Schleifmaschine hat ferner ein im dargestellten Beispiel ortsfestes Gehäuse 20, aus dem zwei waagerechte Kolbenstangen 22 in Richtung zur Einspannvorrichtung 10 herausragen. Die Kolbenstangen 22 gehören zu je einer innerhalb des Gehäuses 20 angeordneten pneumatischen Kolbenzylindereinheit üblicher Bauart und tragen gemeinsam einen Schlitten 24, der in Richtung des in Fig. 1, 2 und 4 eingezeichneten Doppelpfeils B hin- und herbewegbar ist. Aus dem Gehäuse 20 ragt ferner parallel zu den Kolbenstangen 22 und in der Mitte zwischen diesen eine weitere Stange 26 heraus, die durch eine hydraulische Dämpfungsvorrichtung 28 mit dem Schlitten 24 verbunden ist.The grinding machine also has a stationary housing 20 in the example shown, from which two horizontal piston rods 22 protrude in the direction of the clamping device 10. The piston rods 22 each belong to a pneumatic piston-cylinder unit of the usual type arranged within the housing 20 and together carry a slide 24 which can be moved back and forth in the direction of the double arrow B shown in FIGS. 1, 2 and 4. A further rod 26, which is connected to the slide 24 by a hydraulic damping device 28, also protrudes parallel to the piston rods 22 and in the middle between them.

Der Schlitten 24 trägt zwei Schleifaggregate 30 und 30' gleicher Bauart, die spiegelsymmetrisch zueinander angeordnet und abgesehen davon, daß sie gemeinsam an allen Bewegungen des Schlittens 24 teilnehmen, voneinander unabgängig sind. Jedes der Schleifaggregate 30 und 30' hat einen Lagerbock 32 bzw. 32' mit einem Fuß 34 bzw. 34', der einen Querschlitz 36 bzw. 36' aufweist. Unter den Querschlitzen 36 und 36' ist im Schlitten 24 je ein in den Zeichnungen nicht sichtbarer Längsschlitz ausgebildet. Durch jeden der Querschlitze 36 und 36' und den zugehörigen Längsschlitz erstreckt sich eine Klemmschraube 38 bzw. 38'. Somit ist es möglich, die Lagerböcke 32 und 32' in unterschiedlichen Abständen voneinander sowie in unterschiedlicher Weise um je eine senkrechte Schwenkachse C bzw. C' geschwenkt auf dem Schlitten 24 festzuklemmen.The carriage 24 carries two grinding units 30 and 30 'of the same type, which are arranged mirror-symmetrically to one another and, apart from the fact that they participate in all the movements of the carriage 24, are independent of one another. Each of the grinding units 30 and 30 'has a bearing block 32 or 32' with a foot 34 or 34 ', which has a transverse slot 36 or 36'. A longitudinal slot, not visible in the drawings, is formed in the slide 24 under the transverse slots 36 and 36 '. A clamping screw 38 or 38 'extends through each of the transverse slots 36 and 36' and the associated longitudinal slot. It is thus possible to clamp the bearing blocks 32 and 32 'on the slide 24 at different distances from one another and in different ways, each pivoted about a vertical pivot axis C or C'.

An jedem der Lagerböcke 32 und 32' ist ein Schleifkörper 40 bzw. 40' auf einem Achsbolzen 42 bzw. 42' gelagert, der eine in der Mittelebene A liegende Drehachse D bzw. D' definiert. Im dargestellten Beispiel sind die Schleifkörper 40 und 40' glatte, leicht ballige Rollen aus Stahl, die auf je einem Wälzlager 44 gelagert sind. Auf jedem der Achsbolzen 42 und 42' ist ferner ein Tragkörper 46 bzw. 46' um die zugehörige Drehachse D bzw. D' schwenkbar gelagert. Jeder der Tragkörper 46 und 46' hat die Form einer senkrechten Platte mit einem im Abstand parallel zum zugehörigen Achsbolzen 42 bzw. 42' angeordneten weiteren Lagerbolzen 48 bzw. 48', auf dem eine Wippe 50 bzw. 50' in einer senkrechten Ebene schwenkbar gelagert ist.On each of the bearing blocks 32 and 32 ', a grinding body 40 or 40' is mounted on an axle bolt 42 or 42 ', which defines an axis of rotation D or D' lying in the central plane A. In the example shown, the grinding wheels 40 and 40 'are smooth, slightly spherical rollers made of steel, which are each mounted on a roller bearing 44. On each of the axle bolts 42 and 42 'there is also a support body 46 or 46 'pivotally mounted about the associated axis of rotation D or D'. Each of the supporting bodies 46 and 46 'has the shape of a vertical plate with a further bearing bolt 48 or 48' arranged parallel to the associated axle bolt 42 or 42 ', on which a rocker 50 or 50' is pivotably mounted in a vertical plane is.

Jede der Wippen 50 und 50' trägt einen Motor 52 bzw. 52', beispielsweise einen mit Drucköl betreibbaren Drehflügelmotor, mit einer Antriebsrolle 54 bzw. 54', die durch ein handelsübliches Schleifband 56 bzw. 56' mit dem zugehörigen Schleifkörper 40 bzw. 40' verbunden ist und diesen antreibt. An jeder der Wippen 50 und 50' ist, um das zugehörige Schleifband 56 bzw. 56' straffzuhalten, ein zum zugehörigen Lagerbolzen 48 bzw. 48' paralleler Bolzen 58 bzw. 58' befestigt, auf dem eine Spannfeder 60 bzw. 60' von der Form einer Wäscheklammerfeder gelagert ist. Die Spannfedern 60 und 60' stützen sich mit je einem Schenkel an einem Stift 62 bzw. 62' ab, der am zugehörigen Tragkörper 46 bzw. 46' befestigt ist, und drücken mit einem zweiten Schenkel gegen die zugehörige Wippe 50 bzw. 50'.Each of the rockers 50 and 50 'carries a motor 52 or 52', for example a rotary vane motor which can be operated with pressure oil, with a drive roller 54 or 54 'which is carried out by a commercially available grinding belt 56 or 56' with the associated grinding body 40 or 40 'is connected and drives it. On each of the rockers 50 and 50 ', in order to keep the associated grinding belt 56 or 56' taut, a bolt 58 or 58 'parallel to the associated bearing bolt 48 or 48' is fastened, on which a tension spring 60 or 60 'of the Form of a clothespin spring is stored. The tension springs 60 and 60 'are supported with one leg each on a pin 62 or 62', which is fastened to the associated support body 46 or 46 ', and press with a second leg against the associated rocker 50 or 50'.

Die Lagerböcke 32 und 32' haben je einen kreisbogenförmigen Schlitz 64 bzw. 64', dessen Mittelpunkt auf der zugehörigen Drehachse D bzw. D' liegt, und durch den sich eine in den zugehörigen Tragkörper 46 bzw. 46' eingeschraubte Klemmschraube 66 bzw. 66' erstreckt. Die Tragkörper 46 und 46' sind somit unabhängig voneinander in je einer Stellung festklemmbar, in der das zugehörige Schleifband 56 bzw. 56' mehr oder weniger stark gegen die Mittelebene A geneigt ist.The bearing blocks 32 and 32 'each have an arcuate slot 64 or 64', the center of which lies on the associated axis of rotation D or D ', and through which a clamping screw 66 or 66 screwed into the associated support body 46 or 46' 'extends. The support bodies 46 and 46 'can thus be clamped independently of one another in a position in which the associated grinding belt 56 or 56' is more or less inclined towards the central plane A.

Gemäß Fig. 1 bis 3 ist die Schleifmaschine zum Beschleifen der Henkelenden 18 und 18' eines Henkels 16 eingerichtet, der an einen zylindrischen Gefäßkörper angarniert werden soll. Dementsprechend sind die beiden Schleifaggregate 30 und 30' symmetrisch in bezug auf eine senkrechte Symmetrieebene E der Schleifmaschine angeordnet, und zwar derart, daß die in der Mittelebene A liegenden Drehachsen D und D' der Schleifkörper 40 und 40' miteinander fluchten. Dabei ist es am einfachsten, wenn auch nicht unbedingt erforderlich, daß die beiden Tragkörper 46 und 46' gleich angeordnet sind, beispielsweise - wie in Fig. 2 mit vollen Linien dargestellt - derart, daß auch die Drehachsen der Antriebsrollen 54 und 54' in der Mittelebene A liegen und somit die Schleifbänder 56 und 56' sich waagerecht erstrecken.According to FIGS. 1 to 3, the grinding machine is set up for grinding the handle ends 18 and 18 'of a handle 16 which is to be attached to a cylindrical vessel body. The two grinding units 30 are accordingly and 30 'arranged symmetrically with respect to a vertical plane of symmetry E of the grinding machine, in such a way that the axes of rotation D and D' of the grinding bodies 40 and 40 'lying in the central plane A are aligned with one another. It is easiest, if not absolutely necessary, that the two support bodies 46 and 46 'are arranged identically, for example - as shown in Fig. 2 with full lines - such that the axes of rotation of the drive rollers 54 and 54' in the Center plane A and thus the grinding belts 56 and 56 'extend horizontally.

Die waagerechte Anordnung beider Schleifbänder 56 und 56' kann beibehalten werden, wenn die Schleifmaschine, wie in Fig. 4 dargestellt, zum Beschleifen der Henkelenden eines Henkels eingestellt wird, der an einen Gefäßkörper 68 mit konvexem Außenprofil angarniert werden soll. In diesem Fall sind die Lagerböcke 32 und 32' im Vergleich mit der Anordnung gemäß Fig. 1 bis 3 derart um ihre Schwenkachse C bzw. C' geschwenkt, daß die Tragkörper 46 divergieren.The horizontal arrangement of both grinding belts 56 and 56 'can be maintained if the grinding machine, as shown in FIG. 4, is set for grinding the handle ends of a handle which is to be attached to a vessel body 68 with a convex outer profile. In this case, the bearing blocks 32 and 32 'are pivoted about their pivot axis C or C' in comparison with the arrangement according to FIGS. 1 to 3 in such a way that the support bodies 46 diverge.

Wenn jedoch die Henkelenden von Henkeln zu beschleifen sind, die an Gefäßkörper mit konkaver Außenkontur angarniert werden sollen, ist es erforderlich, die Tragkörper 46 und 46' um die zugehörige Drehachse D bzw. D' voneinander weg nach oben bzw. nach unten zu schwenken. Dadurch wird die Möglichkeit geschaffen, die Lagerböcke 32 und 32' um ihre Schwenkachse C bzw. C' derart zu schwenken, daß die Tragkörper 46 und 46' einander kreuzen und somit die Mantelflächen der Schleifkörper 40 und 40', also auch die Schleifbänder 56 und 56', ein zum konkaven Profil des Gefäßkörpers komplementäres Profil beschreiben.However, if the handle ends of handles are to be ground, which are to be attached to the vessel body with a concave outer contour, it is necessary to pivot the supporting bodies 46 and 46 'up and down about the associated axis of rotation D and D', respectively. This creates the possibility of pivoting the bearing blocks 32 and 32 'about their pivot axis C or C' in such a way that the support bodies 46 and 46 'cross each other and thus the outer surfaces of the grinding bodies 40 and 40', that is to say also the grinding belts 56 and 56 ', describe a profile complementary to the concave profile of the vessel body.
