Definitions
- the invention relates to a profile grinding unit with at least two tool holders fastened in a frame, to each of which a grinding tool for machining workpieces transported past the profile grinding unit in a working plane is fastened, the tool holders being arranged in different angular positions and their tools complementing each other to the desired profile shape (see for example DE-A-30 34 206).
- the invention is therefore based on the object of designing a profile grinding unit of the type mentioned at the outset in such a way that a perfect grinding result is achieved with the use of a plurality of grinding tools while requiring little space.
- the profile grinding unit according to the invention thus has an arrangement of the tools which enable the grinding process to be carried out in one gear, but do not have the disadvantages of the rigid shape of a one-piece tool.
- the tools at an angle to each other can compensate for any thickness tolerance of the workpiece by a certain flexibility in the axial direction of their tool holder.
- the belt guided in the direction of transport runs simultaneously over the several tools. In the overlapping area, the two tools alternately determine the grinding shape in an identical manner.
- the tool holder can be fastened in the frame in different angular positions.
- This can preferably be achieved in that the tool holders are fastened to a holder with a contact surface arranged perpendicular to the conveying plane and direction and can be detachably fastened to the holder in various angular positions.
- the releasable fastening is very simple if the holder and / or the tool holder have a plurality of holes which are aligned with at least two holes of the tool holder or the holder for fastening the respective tool holder in different angular positions.
- the tool is fastened to the tool holder with a connecting piece which can be pivoted in the direction of the angular position, wherein the connecting piece can also be translationally displaceable perpendicular to the longitudinal axis of the tool holder.
- the connector can be used to make fine adjustments to the tools.
- the design of the profile grinding unit according to the invention can also be realized with a rotating tool turret which has a plurality of tool holder sets, the tool holders being arranged in different angular positions in each tool holder set, so that their tools complement each other to the desired profile shape. This makes it possible to effectively switch toothed tools for different profile shapes by rotating the tool turret without the need for major conversion measures.
- the tool turret can be rotated both about an axis of rotation lying in the direction of transport of the workpieces and about an axis of rotation arranged perpendicularly thereto.
- Figure 1 shows a plan view of the effective sides of a workpiece 1 facing two tools 2, 3, which - as shown in Figure 2 - are at an angle to each other and overlap in a symmetrical to the conveying plane 4 overlap area 5 so that one in the Conveying plane 4 moving workpiece 1 in the overlap area 5 alternately abuts one and the other tool 2, 3.
- the tool holders 7, 8 are both at an angle of 45 ° to the transport plane 4 and thus form an angle of 90 ° to one another.
- the connecting pieces 5, 6 are arranged offset from the central axis of the tool holder towards the workpiece and thus free up the space for the inner ends of the base plates 9, 10.
- the side edges of the tools 2 ', 3' are designed so beveled to the conveying plane 4 that the size of the base plates 9 ', 10' can be kept so small that they practically do not overlap at their inner ends . Accordingly, the connecting pieces 5 ', 6' can be formed symmetrically to the longitudinal axis of the tool holder 7, 8.
- Figures 1 to 3 show that in the same place in the conveying direction of the complete grinding process for the rounded edge of the workpiece 1 is carried out, however, with two tools 2, 3 and 2 ', 3', which are at an angle of, for example, 90 ° to each other and thus thickness tolerances of the workpiece 1 due to a low mobility of the tool in the direction of the central axis of the tool holder 7, 8 can compensate.
- the arrangement of the two tools 2, 3 and 2 ', 3' at an angle of 45 ° to the conveying plane 4 is expedient.
- a different angular position can be more advantageous.
- FIG. 4 therefore shows a holder 10 to which tool holders 7, 8 can be fastened in different angular positions.
- the holder 10 has a sickle-like front attachment 11, which is provided with an arc-like arrangement of a plurality of holes 12.
- the bracket 10 is fastened with a fastening flange 13 to a crossbar (not shown) of a frame of the profile grinding unit.
- a bracket 10 ' is shown, the crescent-like approach 11' is much wider and has a plurality of holes 12 which form a crescent-like grid.
- This bracket 10 'therefore allows a greater range of variation in the attachment of the tool holder 7, 8th
- Figure 6 shows a tool holder 7 which is screwed to the brackets 10, 10 '.
- the tool holder 7 has two lateral lugs 14, each carrying a hole 15, the spacing of which corresponds to the spacing of the holes 12 of the brackets 10, 10 ', as will be explained with reference to FIG. 9.
- the side lugs 14 ', 14 ⁇ are designed so that one lug 14' carries three parallel holes 16 a aligned with the longitudinal axis of the tool holder 7 a, while the other side lug 14 'with an elongated hole 16 'is equipped, which extends perpendicular to the longitudinal axis of the tool holder 7 a. Due to the elongated hole 16 ', this tool holder 7 a can be easily attached in the hole pattern of the secure projection 11' of the bracket 10 'in different angular positions.
- a large variation of the fastenings can be achieved with the tool holder 7 b, which is shown in Figure 8.
- Rivets or similar can be replaced.
- Figure 9 illustrates that the connecting pieces 5 ', 6' are preferably laterally displaceable relative to the associated tool holder 7, 8, that is perpendicular to its longitudinal axis, and are also tiltable to its longitudinal axis. This allows a fine adjustment of the tools 2 ', 3' to be achieved, so that an optimal adaptation to the edge of the workpiece 1 to be ground can be achieved.
- Figure 9 illustrates that an extended in the transport direction grinding belt 18 is guided over the tools 2 ', 3', so that the tools 2 ', 3' for the grinding pressure in the desired shape are responsible, while the actual abrasive is present on the grinding belt 18.
- the grinding belt 18 is essentially at the same time on the tools 2 ', 3', so that the advantages of a uniform grinding process, as is the case with a single tool, set.

Abstract
Description
Die Erfindung betrifft ein Profilschleifaggregat mit wenigstens zwei in einem Rahmen befestigten Werkzeughaltern, an denen jeweils ein Schleifwerkzeug zum Bearbeiten von an dem Profilschleifaggregat in einer Arbeitsebene vorbeitransportierten Werkstücken befestigt ist, wobei die Werkzeughalter in verschiedenen Winkelstellungen angeordnet sind und sich ihre Werkzeuge zu der gewünschten Profilform ergänzen (siehe z.B. DE-A-30 34 206).The invention relates to a profile grinding unit with at least two tool holders fastened in a frame, to each of which a grinding tool for machining workpieces transported past the profile grinding unit in a working plane is fastened, the tool holders being arranged in different angular positions and their tools complementing each other to the desired profile shape (see for example DE-A-30 34 206).
Für bestimmte Schleifaufgaben ist es zweckmäßig, die zu schleifende Profilform mit mehreren, beispielsweise zwei Werkzeugen zu bearbeiten. Der Grund hierfür kann in einer problematischen Positionierung nur eines einzigen Werkzeuges liegen. Darüber hinaus führt die Verwendung eines einzigen Werkzeuges bei einem von dem Werkzeug umfaßten Profil zu dem Nachteil, daß Toleranzen in der Werkstückdicke zu erheblichen Beeinträchtigungen des Schleifergebnisses führen. Werkzeuge, die hingegen nur jeweils einen Teil des Profils schleifen, sind gegenüber Änderungen der Werkstückdicke weniger anfällig. Es ist daher bekannt, kompliziertere Profilformen oder Profilformen, die auf gegenüberliegenden Seiten zu schleifen sind, mit mehreren Werkzeugen zu bearbeiten, die jeweils nur einen Teilschliff bewirken. Diese Werkzeuge sind regelmäßig in einer Halterung in Förderrichtung unmittelbar hintereinander angeordnet. Bei Bandschleifmaschinen läuft das in Transportrichtung geführte Band somit nacheinander über die mehreren Werkzeuge. Dabei entsteht ein höherer Platzbedarf in Förderrichtung. Darüber hinaus sind bei speziellen Schleifaufgaben Probleme am Ende des Schleifbereichs des letzten Werkzeuges nicht auszuschließen.For certain grinding tasks, it is advisable to machine the profile shape to be ground with several, for example two, tools. The reason for this can be the problematic positioning of only one tool. In addition, the use of a single tool with a profile encompassed by the tool leads to the disadvantage that tolerances in the workpiece thickness lead to considerable impairments of the grinding result. However, tools that only grind part of the profile are less susceptible to changes in workpiece thickness. It is therefore known to make more complicated profile shapes or profile shapes that are to be ground on opposite sides with several tools edit, which only cause a partial grinding. These tools are regularly arranged one behind the other in a holder in the conveying direction. In the case of belt grinding machines, the belt guided in the transport direction thus runs over the several tools one after the other. This creates a higher space requirement in the conveying direction. In addition, problems at the end of the grinding area of the last tool cannot be ruled out for special grinding tasks.
Der Erfindung liegt daher die Aufgabe zugrunde, ein Profilschleifaggregat der eingangs erwähnten Art so auszubilden, daß bei geringem Platzbedarf ein einwandfreies Schleifergebnis bei der Verwendung mehrerer Schleifwerkzeuge erzielt wird.The invention is therefore based on the object of designing a profile grinding unit of the type mentioned at the outset in such a way that a perfect grinding result is achieved with the use of a plurality of grinding tools while requiring little space.
Diese Aufgabe wird erfindungsgemäß bei einem Profilschleifaggregat der eingangs erwähnten Art dadurch gelöst, daß die Werkzeughalter in Transportrichtung im wesentlichen auf gleicher Höhe angeordnet sind und daß die Werkzeuge zweier benachbarter Werkzeughalter durch eine komplemetär gezahnte Ausbildung der zueinander zeigenden Kanten ineinandergreifend die gewünschte Profilform bilden.This object is achieved according to the invention in a profile grinding unit of the type mentioned at the outset in that the tool holders are arranged essentially at the same height in the direction of transport and in that the tools of two adjacent tool holders form the desired profile shape in an interlocking manner by a complementary toothed design of the edges pointing towards one another.
Das erfindungsgemäße Profilschleifaggregat weist somit eine Anordnung der Werkzeuge auf, die die Durchführung des Schleifvorganges in einem Gang ermöglichen, nicht aber die Nachteile der starren Form eines einteiligen Werkzeuges aufweisen. Die in einem Winkel zueinander stehenden Werkzeuge können eine etwaige Dickentoleranz des Werkstückes durch eine gewissen Nachgiebigkeit in axialer Richtung ihres Werkzeughalters ausgleichen. Bei einer Bandschleifmaschine läuft das in Transportrichtung geführte Band gleichzeitig über die mehreren Werkzeuge. In dem überlappenden Bereich bestimmen die beiden Werkzeuge abwechselnd die Schleifform in identischer Weise.The profile grinding unit according to the invention thus has an arrangement of the tools which enable the grinding process to be carried out in one gear, but do not have the disadvantages of the rigid shape of a one-piece tool. The tools at an angle to each other can compensate for any thickness tolerance of the workpiece by a certain flexibility in the axial direction of their tool holder. In a belt grinder, the belt guided in the direction of transport runs simultaneously over the several tools. In the overlapping area, the two tools alternately determine the grinding shape in an identical manner.
Zur Durchführung verschiedener Schleifaufgaben und zur Anpassung an die gewünschten Profilformen ist es zweckmäßig, wenn die Werkzeughalter in verschiedenen Winkelstellungen im Rahmen befestigbar sind. Dies kann vorzugsweise dadurch realisiert sein, daß die Werkzeughalter an einer Halterung mit einer senkrecht zur Förderebene und -richtung angeordneten Anlagefläche befestigt und an der Halterung in verschiedenen Winkelstellungen lösbar befestigbar sind.To carry out various grinding tasks and to adapt to the desired profile shapes, it is expedient if the tool holder can be fastened in the frame in different angular positions. This can preferably be achieved in that the tool holders are fastened to a holder with a contact surface arranged perpendicular to the conveying plane and direction and can be detachably fastened to the holder in various angular positions.
Die lösbare Befestigung gestaltet sich sehr einfach, wenn die Halterung und/oder die Werkzeughalter eine Mehrzahl von Löchern aufweisen, die mit wenigstens zwei Löchern des Werkzeughalters bzw. der Halterung zur Befestigung des jeweiligen Werkzeughalters in verschiedenen Winkelstellungen fluchten.The releasable fastening is very simple if the holder and / or the tool holder have a plurality of holes which are aligned with at least two holes of the tool holder or the holder for fastening the respective tool holder in different angular positions.
In jedem Fall ist es vorteilhaft, wenn das Werkzeug an dem Werkzeughalter mit einem in Richtung der Winkelstellung verschwenkbaren Verbindungsstück befestigt ist, wobei das Verbindungsstück zusätzlich auch noch senkrecht zur Längsachse des Werkzeughalters translatorisch verschiebbar sein kann. Durch das Verbindungsstück lassen sich Feinjustierungen der Werkzeuge zueinander durchführen. Die erfindungsgemäße Ausbildung des Profilschleifaggregats läßt sich auch mit einem rotierenden Werkzeugrevoler verwirklichen, der eine Mehrzahl von Werkzeughaltersätzen aufweist, wobei in jedem Werkzeughaltersatz die Werkzeughalter in verschiedenen Winkelstellungen angeordnet sind, so daß sich ihre Werkzeuge zu der gewünschten Profilform ergänzen. Dadurch ist es möglich, durch Rotation des Werkzeugrevolvers verzahnte Werkzeuge für verschiedene Profilformen wirksam zu schalten, ohne daß es hierfür größerer Umbaumaßnahmen bedarf. Die Rotation des Werkzeugrevolvers kann dabei sowohl um eine in Transportrichtung der Werkstücke liegende Drehachse als auch um eine senkrecht dazu angeordnete Drehachse erfolgen.In any case, it is advantageous if the tool is fastened to the tool holder with a connecting piece which can be pivoted in the direction of the angular position, wherein the connecting piece can also be translationally displaceable perpendicular to the longitudinal axis of the tool holder. The connector can be used to make fine adjustments to the tools. The design of the profile grinding unit according to the invention can also be realized with a rotating tool turret which has a plurality of tool holder sets, the tool holders being arranged in different angular positions in each tool holder set, so that their tools complement each other to the desired profile shape. This makes it possible to effectively switch toothed tools for different profile shapes by rotating the tool turret without the need for major conversion measures. The tool turret can be rotated both about an axis of rotation lying in the direction of transport of the workpieces and about an axis of rotation arranged perpendicularly thereto.

Figur 1 zeigt eine Draufsicht auf die zu einem Werkstück 1 zeigenden wirksamen Seiten zweier Werkzeuge 2, 3, die - wie Figur 2 verdeutlicht - in einem Winkel zueinander stehen und sich in einem symmetrisch zur Förderebene 4 liegenden Überlappungsbereich 5 so überlappen, daß ein in der Förderebene 4 bewegtes Werkstück 1 in dem Überlappungsbereich 5 abwechselnd an dem einen und an dem anderen Werkzeug 2, 3 anliegt.Figure 1 shows a plan view of the effective sides of a
Bei der in Figur 2 dargestellten Befestigung der Werkzeuge 2, 3 mit Verbindungsstücken 5, 6 an jeweils einem Werkzeughalter 7, 8 sind die Kanten der Werkzeuge 2, 3 parallel und senkrecht zur Förderrichtung ausgebildet, so daß auch das Werkzeug 2, 3 tragende Basisplatten 9, 10 gezahnt ausgebildet sein müssen, um in der für diese Ausbildung der Werkzeuge 2, 3 nötigen Weise durcheinander hindurchgreifen zu können.When the
Die Werkzeughalter 7, 8 stehen beide im Winkel von 45° zur Transportebene 4 und bilden somit zueinander einen Winkel von 90°. Um den erforderlichen Platz für die Basisplatten 9, 10 zu schaffen, sind die Verbindungsstücke 5, 6 aus der Mittelachse der Werkzeughalter zum Werkstück hin versetzt angeordnet und geben somit den Raum für die inneren Enden der Basisplatten 9, 10 frei.The
Bei dem in Figur 3 dargestellten Ausführungsbeispiele sind die Seitenkanten der Werkzeuge 2′,3′ so zur Förderebene 4 abgeschrägt ausgebildet, daß sich die Größe der Basisplatten 9′, 10′ so klein halten läßt, daß sich diese an ihren inneren Enden praktisch nicht überlappen. Demzufolge können die Verbindungsstücke 5′, 6′ symmetrisch zur Längsachse der Werkzeughalter 7, 8 ausgebildet sein.In the embodiments shown in Figure 3, the side edges of the tools 2 ', 3' are designed so beveled to the
Die Figuren 1 bis 3 lassen erkennen, daß an derselben Stelle in der Förderrichtung der vollständige Schleifvorgang für die abgerundete Kante des Werkstücks 1 durchgeführt wird, jedoch mit zwei Werkzeugen 2, 3 bzw. 2′, 3′, die in einem Winkel von beispielsweise 90° zueinander stehen und somit Dickentoleranzen des Werkstücks 1 aufgrund einer geringen Beweglichkeit des Werkzeugs in Richtung der Mittelachse der Werkzeughalter 7, 8 ausgleichen können.Figures 1 to 3 show that in the same place in the conveying direction of the complete grinding process for the rounded edge of the
Für eine in einer Halbkreisprofilform rundgeschliffenen Kante des Werkstücks 1 ist die Anordnung der beiden Werkzeuge 2, 3 bzw. 2′, 3′ in einem Winkel von 45° zur Förderebene 4 zweckmäßig. Für andere Profilformen an den Kanten von Werkstücken 1 kann eine andere Winkelstellung vorteilhafter sein.For an edge of the
Figur 4 zeigt daher ein Halterung 10, an der Werkzeughalter 7, 8 in unterschiedlichen Winkelstellungen befestigbar sind. Die Halterung 10 weist einen sichelartigen vorderen Ansatz 11 auf, der mit einer kreisbogenartigen Anordnung einer Vielzahl von Löchern 12 versehen ist. Die Halterung 10 ist mit einem Befestigungsflansch 13 an einer (nicht dargestellten) Traverse eines Rahmens des Profilschleifaggregats befestigt.FIG. 4 therefore shows a
In dem Ausführungsbeispiel gemäß Figur 5 ist eine Halterung 10′ dargestellt, deren sichelartiger Ansatz 11′ wesentlich breiter ausgebildet ist und eine Vielzahl von Löchern 12 aufweist, die ein sichelartiges Raster bilden. Diese Halterung 10′ erlaubt daher eine größere Variationsbreite bei der Anbringung der Werkzeughalter 7, 8.In the embodiment shown in Figure 5, a bracket 10 'is shown, the crescent-like approach 11' is much wider and has a plurality of
Figur 6 zeigt einen Werkzeughalter 7, der an die Halterungen 10, 10′ anschraubbar ist. Der Werkzeughalter 7 weist zwei seitliche Ansätze 14 auf, die jeweils ein Loch 15 tragen, deren Abstand zu dem Abstand der Löcher 12 der Halterungen 10, 10′ paßt, wie dies anhand der Figur 9 noch verdeutlicht wird.Figure 6 shows a
Bei dem in Figur 6 dargestellten Werkzeughalter 7 a sind die seitlichen Ansätze 14′, 14˝ so ausgebildet, daß der eine Ansatz 14′ drei parallel zur Längsachse des Werkzeughalters 7 a ausgerichtete Rundlöcher 16 trägt, während der andere seitliche Ansatz 14˝ mit einem Langloch 16′ ausgestattet ist, das sich senkrecht zur Längsachse des Werkzeughalters 7 a erstreckt. Aufgrund des Langloches 16′ läßt sich dieser Werkzeughalter 7 a problemlos in dem Lochraster des sicherförmigen Ansatzes 11′ der Halterung 10′ in verschiedenen Winkelstellungen befestigen.In the tool holder 7 a shown in Figure 6, the
Eine große Variationsmöglichkeit der Befestigungen ist mit dem Werkzeughalter 7 b zu erzielen, der in Figur 8 dargestellt ist. An dessen seitlichen Ansätzen 14 befinden sich zahlreiche, in Rasterform angeordnete Löcher 15.A large variation of the fastenings can be achieved with the tool holder 7 b, which is shown in Figure 8. There are
Ein Beispiel für die Befestigung von anhand der Figur 6 erläuterten Werkzeughaltern 7, 8 an einer Halterung 10, wie sie in Figur 4 gezeigt ist, verdeutlicht Figur 9. Die Befestigung erfolgt durch die miteinander fluchtenden Löcher 12, 15 ragende Schrauben 17, die auch durch Nieten o. ä. ersetzt werden können.An example of the attachment of
Figur 9 verdeutlicht, daß die Verbindungsstücke 5′, 6′ vorzugsweise gegenüber dem zugehörigen Werkzeughalter 7, 8 seitlich, also senkrecht zu dessen Längsachse, verschiebbar und zu dessen Längsachse auch kippbar ausgebildet sind. Dadurch läßt sich eine Feinjustierung der Werkzeuge 2′, 3′ erzielen, so daß eine optimale Anpassung an die zu schleifende Kante des Werkstücks 1 erreichbar ist.Figure 9 illustrates that the connecting pieces 5 ', 6' are preferably laterally displaceable relative to the associated
Figur 9 verdeutlicht noch, daß ein in Transportrichtung erstrecktes Schleifband 18 über die Werkzeuge 2′, 3′ geführt ist, so daß die Werkzeuge 2′, 3′ für den Schleifandruck in der gewünschten Formgebung verantwortlich sind, während das eigentliche Schleifmittel auf dem Schleifband 18 vorhanden ist. Das Schleifband 18 liegt im wesentlichen gleichzeitig an den Werkzeugen 2′, 3′ an, so daß sich insoweit die Vorteile eines einheitlichen Schleifvorganges, wie er bei einem einzigen Werkzeug gegeben ist, einstellen.Figure 9 illustrates that an extended in the transport direction grinding belt 18 is guided over the tools 2 ', 3', so that the tools 2 ', 3' for the grinding pressure in the desired shape are responsible, while the actual abrasive is present on the grinding belt 18. The grinding belt 18 is essentially at the same time on the tools 2 ', 3', so that the advantages of a uniform grinding process, as is the case with a single tool, set.
Obwohl die beschriebenen Ausführungsbeispiele lediglich zwei Werkzeuge 2, 3 bzw. 2′, 3′ zeigen, ergibt sich aus dem dargelegten ohne weiteres, daß auch einen Anordnung von drei oder mehr Werkzeugen möglich ist, wobei die aneinanderliegenden Kanten der Werkzeuge verzahnt ausgebildet sind und sich überlappen.Although the exemplary embodiments described only show two
