Abstract
Description
Die Erfindung betrifft eine Abdeckvorrichtung für Gleit- und Führungsbahnen von Maschinen, bestehend aus metallischen Abdeckelementen, die gegeneinander in Längsrichtung der Gleit- oder Führungsbahn verschieblich sind und einander mit parallel zur Gleit- oder Führungsbahn verlaufenden Abdeckbereichen je nach Auszugszustand mehr oder weniger weit überdecken und aus zwischen benachbarten Abdeckelementen angeordneten Federelementen.The invention relates to a cover device for slideways and guideways of machines consisting of metallic cover elements that oppose each other longitudinal the slideway or guideway are movable and parallel to each other with the slide or guideway running covering areas more or less depending on the pull-out condition cover far and from spring elements arranged between adjacent cover elements.
Bei derartigen bekannten Abdeckvorrichtungen sind die Abdeckelemente als U-förmige, abgekantete Blechtunnelstücke ausgebildet. Zwischen zwei benachbarten Tunnelstücken sind Zugfedern gespannt. Die Tunnelstücke übergreifen einander in der Weise, daß jedes Tunnelstück um mindestens seine Blechdicke größer ist als das übergriffene Tunnelstück. Bei dieser bekannten Konstruktion sind die Abdeckelemente einer Abdeckvorrichtung notwendig sämtlich unterschiedlich ausgebildet. Durch die unterschiedliche Ausbildung sämtlicher Abdeckelemente ergibt sich ein hoher Fertigungsaufwand, der zu einem hohen Herstellungspreis führt.In such known covering devices are the cover elements as U-shaped, bent sheet metal tunnel pieces educated. Tension springs are tensioned between two adjacent tunnel sections. Spread over the tunnel sections each other in such a way that each tunnel piece by at least its sheet thickness is greater than the overlapped one Tunnel piece. In this known construction, the cover elements are a cover device necessary all trained differently. Because of the different training all Covering elements result in a high manufacturing cost, which leads to a leads to high manufacturing prices.
Dieser Nachteil gilt auch für Abdeckvorrichtungen mit einem ähnlichen Aufbau, bei dem die tunnelförmigen Abdeckelemente nicht über Federmittel miteinander verbunden sind. Bei derartigen Abdeckvorrichtungen werden die Abdeckelemente nicht während des Auszugsvorgangs gleichmäßig gegeneinander verschoben, sondern nacheinander bis zum Erreichen ihrer Auszugslänge nacheinander aus dem zusammengeschobenen Stapel herausgezogen.This disadvantage also applies to covering devices with a similar one Structure in which the tunnel-shaped Cover elements do not have Spring means are interconnected. With such cover devices the cover elements are not evenly against each other during the pull-out process shifted, but one after the other until their extension length is reached pulled out of the stack pushed together.
Beide vorerwähnten Abdeckvorrichtungen sind dickwandig ausgebildet und für höhere Beschleunigungen und Verfahrgeschwindigkeiten nicht geeignet.Both of the aforementioned cover devices are thick-walled and for higher Accelerations and travel speeds are not suitable.
Es ist auch bekannt, Abdeckvorrichtungen für Gleit-
und Führungsbahnen
so auszubilden, daß sie
aus einem Faltenbalg bestehen, an dessen Faltenspitzen Blechlamellen

Ausgehend von diesem Stand der Technik liegt der Erfindung die Aufgabe zugrunde, eine ausschließlich aus metallischen Abdeckelementen und zwischen diesen angeordneten Federele menten bestehende Vorrichtung der als bekannt vorausgesetzten Art so auszubilden, daß sie aus über die gesamte Auszugslänge gleich ausgebildeten Abdeckelementen besteht, eine hohe Lebensdauer besitzt und für hohe Beschleunigungen und Verfahrgeschwindigkeiten gut geeignet ist.Based on this state of the art the object of the invention, one exclusively metallic cover elements and arranged between these Federele elements to design existing devices of the type presumed to be known, that she from over the entire extension length consist of the same trained cover elements, a long service life owns and for high Accelerations and travel speeds are well suited.
Die Lösung dieser Aufgabe erfolgt mit den Merkmalen des Schutzanspruchs 1.This task is solved with the features of protection claim 1.
Bevorzugte Ausführungsformen der Erfindung sind in den Unteransprüchen beschrieben.Preferred embodiments of the invention are in the subclaims described.
Die Ausbildung der metallischen Abdeckelemente als quer zur Auszugsrichtung sich erstreckende Winkelprofile erlaubt eine besonders einfache Fertigung aus in einer Abdeckvorrichtung völlig gleich ausgebildeten Abdeckelementen. Bei Verwendung von paarweise ausgebildeten und angeordneten Blattfeder-Verbindungselementen zur Verbindung benachbarter Abdeckelemente werden die Abdeckelemente beim Ausziehen parallel zueinander geführt. Dabei können zusätzliche Gleitführungselemente in vielen Anwendungsfällen vollständig entfallen. Die Verwendung von Blattfeder-Verbindungselementen zur Verbindung benachbarter Abdeckelemente führt dazu, daß im Blockzustand die Blattfederelemente einerseits eng über ihre gesamte Ausdehnung aneinander anliegen, während sie mit ihren Außenseiten jeweils an den quer zur Gleit- oder Führungsbahn verlaufenden zweiten Schenkeln der metallischen Abdeckelemente anliegen. Dabei kann die Anordnung und Ausbildung so gewählt sein, daß, beispielsweise durch Abkantung des parallel zur Gleit- und Führungsbahn verlaufenden ersten Schenkels des Winkelprofils, dessen freies Ende, welches das benachbarte Abdeckelement übergreift, unter Vorspannung auf der Oberfläche des benachbarten, übergriffenen Abdeckelements aufliegt.The formation of the metallic cover elements allowed as an angle profile extending transversely to the extension direction a particularly simple manufacture from in a covering device completely the same trained cover elements. When using pairs trained and arranged leaf spring connecting elements for connection Adjacent cover elements become the cover elements when they are pulled out run parallel to each other. You can additional sliding guide in many applications Completely omitted. The use of leaf spring fasteners Connection of adjacent cover elements leads to the fact that in the block state the leaf spring elements, on the one hand, closely over their entire extent abut each other while them with their outsides in each case across to the glide or guideway abutting second legs of the metallic cover elements. The arrangement and training can be chosen so that, for example by bending the first parallel to the slide and guideway Leg of the angle profile, the free end of which is the neighboring Covers element, under tension on the surface of the neighboring, attacked Cover element rests.
Von besonderem Vorteil ist es auch, wenn die metallischen Abdeckelemente gemäß einem weiteren Vorschlag der Erfindung aus Federstahl bestehen. Eine solche Ausbildung aus Federstahl erlaubt es auch, daß die Blattfeder-Verbindungselemente einstückig mit den zweiten Schenkeln der Abdeckelemente ausgebildet und als Teilbereich aus diesen zweiten Schenkeln ausgeschnitten sind.It is also of particular advantage if the metallic cover elements according to another proposal the invention consist of spring steel. Such training from Spring steel also allows the Leaf spring fasteners in one piece with the second legs formed of the cover elements and as a partial area from these second Thighs are cut out.
Es ist besonders zweckmäßig, wenn zwischen zwei benachbarten zweiten Schenkeln jeweils zwei Paare von Blattfeder-Verbindungselementen oder sogar vier Paare von Blattfeder-Verbindungselementen vorgesehen sind. Die Anordnung kann dabei so gewählt werden, daß die Blattfeder-Verbindungselemente einen in der Breite des zweiten Schenkels gemessenen größtmöglichen Abstand voneinander einhalten. Auf diese Weise ergibt sich die größtmögliche Momentenabstützung durch die Blattfeder-Verbindungselemente.It is particularly useful if between Two adjacent second legs are each provided with two pairs of leaf spring connecting elements or even four pairs of leaf spring connecting elements. The arrangement can be chosen so that the leaf spring connecting elements keep a maximum possible distance from each other measured in the width of the second leg. In this way, the greatest possible torque support is provided by the leaf spring connecting elements.
Es ist auch möglich, die Blattfeder-Verbindungselemente mit über die Länge der Abdeckvorrichtung unterschiedlicher Breite auszubilden. Auf diese Weise können an unterschiedlichen Stellen unterschiedliche Federkräfte erzeugt werden, welche den auftretenden unterschiedlichen Reibungsbedingun gen entsprechen.It is also possible to use the leaf spring fasteners with more than the length to form the covering device of different widths. To this Way can different spring forces are generated at different points be, which the occurring different conditions of friction correspond.
Weitere bevorzugte Ausgestaltungen ergeben sich aus den weiteren Unteransprüchen sowie aus den Zeichnungen und deren nachfolgender Beschreibung. Es zeigen:Further preferred configurations result from the further subclaims and from the drawings and their description below. Show it:

Es ist jedoch auch ohne weiteres möglich, die Blattfeder-Verbindungselemente jeweils durchgehend auszubilden und die erforderliche Federkraft durch eine entsprechende Wahl der Materialdicke sicherzustellen. Außer Federstahl als Blattfedermaterial sind auch andere dauerelastische Materialien verwendbar, wie z.B. Polypropylen.However, it is also readily possible to design the leaf spring connecting elements in each case continuously and to ensure the required spring force by an appropriate choice of the material thickness. In addition to spring steel as the leaf spring material, other permanently elastic materials are also available reversible, such as polypropylene.
