Description

Die Erfindung bezieht sich auf eine Vorrichtung zum Nachbearbeiten einer Stahlkante eines Skis, bestehend aus einer topfförmigen, von einem Motor angetriebenen Schleifscheibe mit quer zur Vorschubrichtung verlaufender Drehachse.The invention relates to a device for reworking a Steel edge of a ski, consisting of a cup-shaped, by an engine driven grinding wheel with axis of rotation running transversely to the feed direction.

Zum Nachbearbeiten abgenützter Stahlkanten eines Skis ist es bekannt (DE 39 14 977 A1), eine von einem Motor angetriebene, topfförmige Schleifscheibe mit zur Vorschubrichtung und zur Lauffläche des Skis unter einem spitzen Winkel geneigter Drehachse einzusetzen, so daß die ringförmige Stirnseite der Schleifscheibe lediglich in einem Umfangsbereich an der außenseitigen Bearbeitungsfläche der Stahlkante anliegt. Mit einer solchen Schleifscheibenanstellung läßt sich zwar ein dem in Längsrichtung taillierten Verlauf der Seitenfläche der Stahlkanten folgender Vorschub erreichen, doch bleiben die Schleifergebnisse unbefriedigend, weil sich wegen des taillierten Stahikantenverlaufes der Anstellwinkel über die Länge der Stahlkante ändert. Außerdem können mit einer solchen Vorrichtung lediglich die Seitenflächen der Stahlkanten, nicht aber deren laufflächenseitige Bearbeitungsflächen geschliffen werden.It is known for reworking worn steel edges of a ski (DE 39 14 977 A1), a cup-shaped grinding wheel driven by a motor to the direction of advance and to the tread of the ski at an acute angle insert inclined axis of rotation so that the annular end face of the grinding wheel only in a peripheral area on the outside machining surface the steel edge rests. With such a grinding wheel adjustment This is true to the lengthwise course of the side surface of the Steel edges reach the following feed, but the grinding results remain unsatisfactory, because of the waisted steel edge profile the angle of attack changes over the length of the steel edge. You can also use a such device only the side surfaces of the steel edges, but not their machining surfaces on the tread side are ground.

Durch die aus der CH-A-661 876 bekannte gattungsgemäße Vorrichtung ist auch eine Schleifbearbeitung der Stahlkante im Bereich nicht nur der außenseitigen, sondern auch der laufflächenseitigen Bearbeitungsfläche moglich.By the generic known from CH-A-661 876 The device is also grinding the steel edge not only on the outside, but also on the tread side Machining area possible.

Der Erfindung liegt somit die Aufgabe zugrunde, eine Vorrichtung zum Nachbearbeiten einer Stahlkante eines Skis der eingangs geschilderten Art so auszugestalten, daß sie einfach handhabbar ist.The invention is therefore based on the object of a device for reworking a steel edge of a ski of the type described above to design that it is easy to handle.

Die Erfindung löst die gestellte Aufgabe dadurch, daß die Schleifscheibe mit dem Motor in einem Gestell einer Anstelleinnchtung um eine Pendelachse anschlagbegrenzt frei drehbar gelagert ist, die quer zur Vorschubrichtung und senkrecht zu Drehachse der Schleifscheibe verläuft. und daß die Anstelleinrichtung zum Anstellen der Schleifscheibe an die Stahlkante in Richtung der Drehachse der Schleifscheibe um eine zur Vorschubrichtung parallele Schwenkachse zwischen zwei Arbeitsstellungen einerseits für die laufflächenseitige und anderseits für die außenseitige Bearbeitungsfläche der Stahlkante schwenkverstellbar ist.The invention solves the problem in that the grinding wheel with limited to the engine in a frame instead of about a pendulum axis Is freely rotatable, which is transverse to the feed direction and runs perpendicular to the axis of rotation of the grinding wheel. and that the adjusting device for positioning the grinding wheel against the steel edge in the direction of the axis of rotation the grinding wheel around a swivel axis parallel to the feed direction between two working positions on the one hand for the tread side and on the other for the outside processing surface of the steel edge swivel adjustable is.

Zufolge der freien Drehbarkeit der Schleifscheibe um eine Pendelachse, die senkrecht zur Drehachse der Schleifscheibe und vorzugsweise ebenfalls senkrecht zur Vorschubnchtung verläuft, kann die Schleifscheibe über die Anstelleinrichtung selbstausrichtend so an die Stahlkante angestellt werden, daß sie in zwei bezüglich einer Sehne gegenüberliegenden Umfangsbereichen anliegt, was eine selbstandige Anpassung der Schleifscheibenausrichtung gegenüber der jeweiligen Bearbeitungsfläche der Stahlkante auch im taillierten Bereich der Längsseite erlaubt. Die wahlweise Bearbeitung entweder der laufflächenseitigen oder der außenseitigen Bearbeitungsfläche der Stahlkante erfolgt durch eine Schwenkverstellung der Anstelleinrichtung, so daß die Drehachse der Schleifscheibe gegenüber der jeweiligen Bearbeitungsfläche senkrecht ausgerichtet wird. Über eine entsprechende Beaufschlagung der anstelleinrichtung, beispielsweise durch einen Stellzylinder kann die Schleifscheibe nach der Schwenkverstellung an die Stahlkante angestellt werden, um dann während des Bearbeitungsvorschubes dem Längsverlauf der Stahlkante selbständig zu folgen, was insbesondere im Bereich der Taillierung des Skis eine entsprechende Nachführung über die anstelleinrichtung erfordert.Due to the free rotation of the grinding wheel around a pendulum axis, the perpendicular to the axis of rotation of the grinding wheel and preferably also perpendicular the feed wheel runs over the adjusting device be aligned to the steel edge so that they are in two circumferential regions lying opposite one another with respect to a chord, which an independent adjustment of the grinding wheel alignment compared to the respective machining area of the steel edge also in the waisted area of the Long side allowed. The optional processing of either the tread side or the outside machining surface of the steel edge is done by a Swivel adjustment of the adjusting device so that the axis of rotation of the grinding wheel aligned perpendicular to the respective processing surface becomes. By means of a corresponding action on the replacement device, for example the grinding wheel can be adjusted by means of an adjusting cylinder after the swivel adjustment be placed on the steel edge and then during the machining feed to independently follow the longitudinal course of the steel edge, which is particularly appropriate in the area of the waist of the ski Tracking of the replacement device required.

Die Anstelleinrichtung kann konstruktiv unterschiedlich ausgeführt sein, weil es ja lediglich darauf ankommt, die Schleifscheibe in Richtung ihrer Drehachse an die zu bearbeitende Fläche der Stahlkante schleifgerecht anzustellen. Zu diesem Zweck kann die Anstelleinrichtung aus einem Schlitten bestehen, der auf einer zur Drehachse der Schleifscheibe parallelen Verschiebeführung verfahrbar ist. In diesem Fall weist die Verschiebeführung die Schwenkachse für die beiden Arbeitsstellungen auf so daß der Schlitten mit seiner Verschiebeführung verschwenkt wird, um nach der Bearbeitung der einen Fäche der Stahlkante deren andere zu bearbeitende Fläche schleifen zu können. Eine andere Möglichkeit der Ausgestaltung der Anstelleinrichtung ergibt sich, wenn die Anstelleinrichtung einen um die Schwenkachse schwenkverstellbaren Träger bildet, an dem das Gestell für die Pendellagerung der Schleifscheibe über ein Gelenkparallelogramm angelenkt ist. Über dieses Gelenkparallelogramm kann die Schleifscheibe an die jeweils zu bearbeitende Fläche der Stahlkante in Richtung der Schleifscheibenachse angestellt werden.The adjusting device can be designed differently because it it just depends on the grinding wheel in the direction of its axis of rotation adjust the surface of the steel edge to be machined to suit the grinding. To this For this purpose, the adjusting device can consist of a sled mounted on a is parallel to the axis of rotation of the grinding wheel sliding guide. In this case, the displacement guide has the pivot axis for the two Working positions so that the slide swings with its sliding guide after machining the one surface of the steel edge to be able to grind other surfaces to be processed. Another possibility the configuration of the adjusting device results when the adjusting device forms a pivotally adjustable carrier about which the Frame for the pendulum bearing of the grinding wheel via a parallelogram is articulated. The grinding wheel can be used with this parallelogram to the surface of the steel edge to be machined in the direction of Grinding wheel axis can be adjusted.

Damit eine möglichst reibungsarme Pendelbewegung für die Schleifscheibe sichergestellt werden kann, kann für die Schleifscheibe mit dem Motor eine zwischen Lagerspitzen als Pendelachse im Gestell des Schlittens gelagerte Halterung vorgesehen werdenThis ensures a low-friction pendulum movement for the grinding wheel can be ensured, can be between the grinding wheel with the motor Bearing tips mounted as a pendulum axis in the frame of the slide be provided

Da der Schwenkwinkel zwischen den beiden Arbeitsstellungen der Anstelleinrichtung den Winkel zwischen den beiden Bearbeitungsflächen der Stahlkante bestimmt. können auch die Neigungswinkel dieser Bearbeitungsflächen über Anschläge für diese Arbeitsstellungen vorgegeben werden. Zu diesem Zweck können verstellbare Anschläge für die Anstelleinrichtung vorgesehen sein. Besonders einfache Konstruktionsverhältnisse lassen sich in diesem Zusammenhang dadurch erzielen, daß die Anschläge für die Anstelleinrichtung aus drehverstellbaren Anschlagnocken bestehen. Zum Festlegen der Sollneigung der Bearbeitungsflächen sind in diesem Fall lediglich die Anschlagnocken in die entsprechende Anschlaglage zu verdrehen, um üblicherweise vorgegebene Neigungswinkel für die Bearbeitungsfächen gewährleisten zu können.Because the swivel angle between the two working positions of the adjusting device the angle between the two machining surfaces of the steel edge certainly. can also adjust the inclination angle of these machining surfaces via stops be specified for these working positions. To this end adjustable stops can be provided for the adjusting device. In this context, particularly simple design relationships can be achieved thereby achieve that the stops for the adjusting device from adjustable There are stop cams. To set the target inclination of the In this case, processing surfaces are only the stop cams in the to turn the appropriate stop position to usually predetermined angles of inclination to guarantee for the processing areas.

Die dargestellte Vorrichtung weist eine topfförmige Schleifscheibe 1 auf, die an die Antriebswelle eines Motors 2 angeflanscht und mit einer Schutzabdeckung 3 versehen ist. Diese aus dem Motor 2 und der Schleifscheibe 1 gebildete Baueinheit ist auf einer im wesentlichen U-formigen Halterung 4 befestigt, deren Schenkel 5 zwischen Lagerspitzen 6 eines die Halterung 4 umgreifenden Gestelles 7 frei drehbar gehalten sind. Diese Lagerspitzen 6 bilden somit für die Schleifscheibe 1 eine Pendelachse a die senkrecht zur Drehachse der Schleifscheibe 1 und zur Vorschubrichtung 8 verläuft, wie dies insbesondere den Fig. 1 und 2 entnommen werden kann.
Das Gestell 7 ist Teil einer Anstelleinrichtung, die gemäß den Fig. 1 bis 4 durch einen Schlitten 9 gebildet wird. der auf einer Verschiebeführung 10 in Richtung der Drehachse der Schleifscheibe 1 verlagerbar ist. Zu diesem Zweck weist die Verschiebeführung 10 zwei parallele Führungsstangen 11 auf, auf denen der Schlitten 9 mit Hilfe von Gleitblocken 12 verschiebbar gelagert ist. Der Verschiebeantrieb für den Schlitten besteht aus einem beispielsweise mit Druckluft beaufschlagbaren Stellzylinder 13. Mit Hilfe dieses Stellzylinders 13 kann demnach die Schleifscheibe 1 an die Stahlkante 14 eines Skis 15 angestellt werden, der auf Stützrollen 16 in Vorschubrichtung 8 an der Schleifscheibe 1 vorbeigefördert wird. Die Schutzabdeckung 3 weist im Bearbeitungsbereich eine Ausnehmung 17 auf, wie sie insbesondere der Fig. 1 entnommen werden kann. Auf Grund der Pendellagerung um die durch die Lagerspitzen 6 gebildete Pendelachse a richtet sich die Schleifscheibe 1 bei einer axialen Beaufschlagung selbststandig gegenüber der zu bearbeitenden Stahlkante 14 aus, so daß trotz der Taillierung des Skis 15 eine exakte Bearbeitung der Längsseite der Stahlkante 14 erreicht wird Die über den Stellzylinder 13 auf die Schleifscheibe 1 aufgebrachte Andrückkraft stellt außerdem eine Nachführung des Schlittens 9 entsprechend der Breitenänderungen des Skis 15 sicher. The device shown has a cup-shaped grinding wheel 1 which is flanged to the drive shaft of a motor 2 and is provided with a protective cover 3. This unit, formed from the motor 2 and the grinding wheel 1, is fastened on an essentially U-shaped holder 4, the legs 5 of which are freely rotatable between bearing tips 6 of a frame 7 encompassing the holder 4. These bearing tips 6 thus form a pendulum axis a for the grinding wheel 1 which runs perpendicular to the axis of rotation of the grinding wheel 1 and to the feed direction 8, as can be seen in particular from FIGS. 1 and 2.
The frame 7 is part of an adjusting device which is formed by a carriage 9 according to FIGS. 1 to 4. which is displaceable on a sliding guide 10 in the direction of the axis of rotation of the grinding wheel 1. For this purpose, the sliding guide 10 has two parallel guide rods 11, on which the slide 9 is slidably supported by means of sliding blocks 12. The sliding drive for the slide consists of an actuating cylinder 13 which can be pressurized with compressed air, for example. With the aid of this actuating cylinder 13, the grinding wheel 1 can accordingly be placed against the steel edge 14 of a ski 15, which is conveyed past the grinding wheel 1 on support rollers 16 in the feed direction 8. The protective cover 3 has a recess 17 in the processing area, as can be seen in particular in FIG. 1. Due to the pendulum bearing around the pendulum axis a formed by the bearing tips 6, the grinding wheel 1 aligns itself with an axial application with respect to the steel edge 14 to be machined, so that despite the waist of the ski 15 an exact machining of the long side of the steel edge 14 is achieved Pressing force applied to the grinding wheel 1 via the actuating cylinder 13 also ensures that the carriage 9 is tracked in accordance with the changes in the width of the ski 15.

Um nicht nur die Längsseite der Stahlkante 14, sondern auch die laufflächenseitige Bearbeitungsfläche der Stahlkante 14 nachschleifen zu können, ist die Schiebeführung 10 auf einer parallel zur Vorschubrichtung 8 verlaufenden Wefle 18 angeordnet, deren Lager mit.19 bezeichnet ist. Auf dieser Welle 18 sitzt ein Stellarm 20, über den die Verschiebeführung 10 zwischen zwei Arbeitssteilungen verschwenkt werden kann, die durch Anschläge 21 und 22 im Zusammenwirken mit einem Gegenanschlag 23 festgelegt werden. Durch die Ausbildung des Gegenanschlages 23 als drehverstellbarer Anschlagnocken können sowohl die außenseitigen als auch die laufflächenseitigen Bearbeitungsflächen in einfacher Weise nach vorgegebenen Neigungswinkeln bearbeitet werden. Zur Drehverstellung eines solches Gegenanschlages 23 kann ein entsprechender Einstellknopf 24 vorgesehen sein. Die Fig. 1 bis 3 zeigen die Arbeitsstellung für ein Schleifen der Längsseite der Stahlkante 14. In dieser Arbeitsstellung wirkt der Gegenanschlag 23 mit dem Anschlag 21 zusammen.To not only the long side of the steel edge 14, but also the tread side To be able to regrind the machining surface of the steel edge 14 is Sliding guide 10 on a Wefle running parallel to the feed direction 8 18 arranged, the bearing is designated 19. A sits on this shaft 18 Actuating arm 20, via which the sliding guide 10 between two work divisions can be pivoted by the stops 21 and 22 in cooperation be determined with a counter stop 23. Through training the counter-stop 23 as a rotatable stop cam can both the outside as well as the tread side machining surfaces in easier Edited according to predetermined angles of inclination. For Rotary adjustment of such a counter-stop 23 can be a corresponding one Adjustment button 24 may be provided. 1 to 3 show the working position for grinding the long side of the steel edge 14. In this working position the counter-stop 23 together with the stop 21.

Für die Bearbeitung der Laufflächenseite der Stahlkante 14 wird die Verschiebeführung 10 über den Stellarm 20 um die Welle 18 in die Arbeitsstellung nach der Fig. 4 verschwenkt, in der der Anschlag 22 zum Tragen kommt. Demensprechend wird die Schleifscheibe 1 um eine durch die Welle 18 gebildete, zur Vorschubrichtung 8 parallele Schwenkachse b zwischen ihren beiden Arbeitsausrichtungen verstellt. Durch eine Beaufschlagung des Stellzylinders 13 wird die Schleifscheibe 1 unabhängig von der jeweiligen Arbeitsstellung angestellt. Allerdings legt sich die Schleifscheibe 1 im Vergleich mit einer Bearbeitung der Stahlkantenlängsseite in einem gegenüberliegenden Umfangsbereich an die Stahlkante 14 an, was eine Ausbildung der Schutzabdeckung 3 mit zwei einander gegenüberliegenden Ausnehmungen 17 erfordert. In beiden Arbeitsstellungen bildet die Stahlkante 14 bezüglich der nngförmigen Stirnfläche der topfförmigen Schleifscheibe 1 eine Sehne, so daß durch das Anliegen der Schleifscheibe 1 an zwei einander bezüglich dieser Sehne gegenüberliegenden Umfangsbereichen durch die pendelbare Lagerung eine genaue Schleifscheibenführung gegenüber der Stahlkante 14 sichergestellt wird, was eine wesentliche Voraussetzung für ein exaktes Nachbearbeiten der Stahlkante 14 darstellt. The sliding guide is used for machining the tread side of the steel edge 14 10 via the actuating arm 20 around the shaft 18 in the working position after Fig. 4 pivots, in which the stop 22 comes into play. Accordingly the grinding wheel 1 is formed by a shaft 18 for Feed direction 8 parallel pivot axis b between their two working orientations adjusted. By acting on the actuating cylinder 13 the grinding wheel 1 is set independently of the respective working position. However, the grinding wheel 1 lays down in comparison with machining the Steel edge long side in an opposite circumferential area to the Steel edge 14 on what a formation of the protective cover 3 with two each other opposite recesses 17 required. In both working positions forms the steel edge 14 with respect to the nng shaped end face of the cup-shaped grinding wheel 1 a tendon, so that by the concern of Grinding wheel 1 on two opposite each other with respect to this chord Precise grinding wheel guidance thanks to the pendulum mounting against the steel edge 14 is ensured, which is an essential Prerequisite for an exact reworking of the steel edge 14.

Damit die Pendelbewegung der aus Schleifscheibe 1 und Motor 2 gebildeten Baueinheit auf das erforderliche Maß begrenzt wird, können entsprechende Anschläge 25 vorgesehen sein, die gemaß dem Ausführungsbeispiel als abgewinkelte Ansätze an einem der Schenkel 5 der Halterung 4 ausgebildet sind und mit dem Gestell 7 zusammenwirken. Diese Anschläge sind insbesondere dann wichtig, wenn die Schleifscheibe 1 am Beginn bzw. am Ende des Schleifvorganges nur in einem der beiden Umfangsbereiche an der Stahikante 14 anliegt, weil der in Vorschubnchfung hintere Umfangsbereich die Bearbeitungsfläche noch nicht erreicht oder der vordere Umfangsbereich die Bearbeitungsflache bereits verlassen hatSo that the pendulum movement of the grinding wheel 1 and motor 2 formed Unit is limited to the required level, can be appropriate Stops 25 are provided, which according to the embodiment as angled lugs formed on one of the legs 5 of the bracket 4 are and cooperate with the frame 7. These attacks are special important if the grinding wheel 1 at the beginning or at the end of Grinding process only in one of the two peripheral areas on the steel edge 14 is present, because the rear circumferential area in the feed test is the machining surface not yet reached or the front circumferential area of the processing area has already left

Die Anstelleinrichtung entsprechend der Fig. 5 besteht nämlich aus einem auf der Welle 18 gelagerten Träger 26. der mit dem Gestell 7 über sowohl am Träger 26 als auch am Gestell 7 angelenkte Führungswangen 27 verbunden ist. Diese Führungswangen 27 bilden ein Gelenkparallelogramm 28 zur Anstellung der Schleifscheibe 1 in Richtung ihrer Drehachse. Die Anstellbewegung erfolgt mittels eines Stellzylinders 29. der z. B. mit Druckluft beaufschlagt wird. Durch ein Verschwenken des Trägers 26 um die Schwenkachse b wird in analoger Weise die Bearbeitung der Stahlkante 14 im Bereich von zwei Bearbeitungsflächen möglichThe device according to FIG. 5 shows one compared to the embodiment 1 to 4 modified adjusting device for the grinding wheel.
