Description
Die vorliegende Erfindung betrifft Führungsschienen von Linearwälzlagern.The present invention relates to guide rails of linear roller bearings.
Aus
Aufgabe der vorliegenden Erfindung ist es, eine Führungsschiene gemäß Anspruch 1 anzugeben, bei der das Herausnehmen und Einsetzen der Maßverkörperung vereinfacht ist.Object of the present invention is a guide rail according to claim 1 to indicate when removing and inserting the material measure is simplified.
Erfindungsgemäß wird diese Aufgabe dadurch gelöst, dass die Abdeckung zerstörungsfrei lösbar an dem Maschinenkörper befestigt ist, wobei zwischen dem Nutgrund und der Maßverkörperung ein Andruckmittel angeordnet ist, dass einerseits an dem Schienenkörper, insbesondere dem Nutgrund abgestützt ist, und das andererseits die Maßverkörperung gegen die Abdeckung andrückt. Die ertindungsgemäße Führungsschiene weist mehrere Vorteile auf. Zum einen kann die Maßverkörperung aus der quer zur Längsrichtung des Schienenkörpers geöffneten Längsnut herausgenommen werden. Das Einsetzen einer neuen Maßverkörperung kann ebenso problemlos über die geöffnete Längsnut erfolgen. Ein weiterer Vorteil ist darin zu sehen, dass während des Einsetzens einer neuen Maßverkörperung diese nicht unnötig beansprucht wird. Bei der bekannten Führungsschiene muss die Maßverkörperung durch die geöffnete Stirnseite des Schienenkörpers in die ansonsten geschlossene Längsnut hinein geschoben werden. Durch dieses Schieben kann beispielsweise die Maßverkörperung in unerwünschter Weise knicken oder aber verkratzt werden, was bei der erfindungsgemäßen Führungsschiene ausgeschlossen ist. Wenn das Andruckmittel beispielsweise durch ein Schaumstoffband gebildet ist, kann dieses die Längsnut vollständig ausfüllen. Die Maßverkörpe rung kann dennoch einfach auf das Schaumstoffband gelegt werden, wobei im Anschluß daran die Abdeckung auf den Schienenkörper erneut aufgesetzt wird. Während des Aufsetzens kommt die Maßverkörperung zur Anlage an die Unterseite der Abdeckung und wird gegen das Andruckmittel angedrückt. Dieses – hier durch ein Schaumstoffband – gebildete Andruckmittel gibt unter diesem Druck problemlos nach und ermöglicht so eine einfache Montage der- Maßverkörperung.According to the invention, this object solved, that the cover can be removed non-destructively the machine body is attached, with a between the groove base and the material measure Pressure means is arranged that on the one hand on the rail body, in particular supported the groove base and, on the other hand, the material measure against the cover presses. The guide rail according to the invention has several advantages. Firstly, the material measure from the transverse to the longitudinal direction of the rail body open longitudinal groove be taken out. The insertion of a new material measure can just as easily over the open longitudinal groove respectively. Another advantage is that during the Insertion of a new material measure this not unnecessary is claimed. In the known guide rail, the measuring standard must be used through the open Front of the rail body in the otherwise closed longitudinal groove are pushed into it. By pushing this, for example Measuring standard in unwanted Kink way or be scratched, what with the guide rail according to the invention is excluded. If the pressure medium, for example, by a foam tape is formed, this can completely fill the longitudinal groove. The Measuring standard can still be easily placed on the foam tape, whereby after that the cover on the rail body is put on again. While touchdown comes to the material measure Attach to the bottom of the cover and is against the pressure medium pressed. This - through here a foam tape - formed Pressure medium yields easily under this pressure and thus enables easy assembly of the measuring standard.
Die Abdeckung und der Schienenkörper können mit Formschlußmitteln versehen sein, die formschlüssig ineinandergreifen, wenn die Abdeckung lösbar an dem Führungskörper befestigt ist. Hier eignen sich alle gängigen Formschlußmittel. In besonders günstiger Weise kann die Abdeckung als Abdeckband ausgebildet sein, dass an seinen Längsseiten abgewinkelte Schenkel aufweist. Diese Schenkel können dann, wenn das Abdeckband auf den Schienenkörper montiert ist, in Hinterschneidungen eingreifen, die an dem Schienenkörper ausgebildet sind. Die Schenkel können beispielsweise aus einem weichen Nichteisenmetall gebildet sein, die sich leicht plastisch verformen lassen. Wenn das Abdeckband auf den Schienenkörper aufgedrückt wird, spreizen die Schenkel unter dem äußeren Druck nach außen und in die Hinterschneidungen des Schienenkörpers hinein. Auf diese Weise ist das Abdeckband einwandfrei an dem Schienenkörper befestigt. Zum Abnehmen des Abdeckbandes kann an diesem gezogen werden, wobei unter dieser äußeren Zugkraft die Schenkel unter erneuter plastischer Verformung im Vorbeigleiten an der Wandung der Hinterschneidungen zurückgedrängt werden.The cover and the rail body can with Positive locking means be provided, the form-fitting interlock when the cover is releasably attached to the guide body is. All common are suitable here Form-locking means. In particularly cheaper The cover can be designed as a cover tape that on its long sides has angled legs. These legs can then if the masking tape on the rail body is mounted, engage in undercuts that are formed on the rail body are. The legs can for example made of a soft non-ferrous metal, that can be easily plastically deformed. If the masking tape on the rail body pressed the legs spread outwards and under the external pressure into the undercuts of the rail body. In this way the masking tape is securely attached to the rail body. To lose weight the masking tape can be pulled on it, under this external tensile force the legs glide past with renewed plastic deformation be pushed back on the wall of the undercuts.
Die Schenkel können aber auch federelastisch ausgebildet sein und unter elastischer Auslenkung in die Hinterschneidungen eingreifen.The legs can also be resilient be formed and with elastic deflection in the undercuts intervention.
Vorzugsweise weist die Abdeckung an ihrer Außenseite eine Oberschicht aus amagnetischem Material, vorzugsweise Edelstahl oder Titanlegierung auf. Dieses Material eignet sich in besonderer Weise, wenn die Längenmesseinrichtung elektromagnetisch arbeitet. Edelstahl oder auch eine Titanlegierung weisen zudem hohe Festigkeiten auf, sind robust und bieten ausreichend Schutz vor unerwünschtem Eindringen von Fremdkörpern und Fremdstoffen in die Längsnut.The cover preferably has on their outside an upper layer made of non-magnetic material, preferably stainless steel or titanium alloy. This material is particularly suitable Way if the length measuring device works electromagnetically. Stainless steel or a titanium alloy also have high strength, are robust and offer sufficient Protection from unwanted Penetration of foreign bodies and foreign matter in the longitudinal groove.
Die Innenseite der Abdeckung kann aus einer Unterschicht aus einem weichen Nichteisenmetall bestehen, wobei die weiter oben bereits erwähnten Schenkel einstückig an der Unterschicht ausgebildet sind.The inside of the cover can consist of an underlayer made of a soft non-ferrous metal, the legs already mentioned above in one piece the lower layer are formed.
Eingangs wurde bereits erwähnt, dass das Andruckmittel durch ein Schaumstoffband gebildet sein kann. Allgemein eignen sich elastisch kompressible Bänder. In diesen Fällen kann die Maßverkörperung problemlos montiert werden. Sie ist einwandfrei auf dem Schaumstoffband gebettet und zugleich gehalten.It was mentioned at the outset that the pressure medium can be formed by a foam tape. Elastically compressible tapes are generally suitable. In these cases the material measure can be easily installed. It is flawless on the foam tape bedded and held at the same time.
Derartige Bänder können problemlos an der Unterseite der Abdeckung befestigt, insbesondere geklebt sein. In diesem Fall wird zuerst die Maßverkörperung in die Längsnut hineingelegt, und im Anschluß daran kann in einem einzigen Arbeitsgang die Abdeckung auf den Schienenkörper aufgesetzt werden, wonach die Montage zur Bereitstellung einer erfindungsgemäßen Führungsschiene abgeschlossen ist.Such tapes can easily be on the bottom attached to the cover, in particular glued. In this case is the material measure first in the longitudinal groove put in, and after that the cover can be placed on the rail body in a single operation be, after which the assembly to provide a guide rail according to the invention is completed.
In günstiger Weise ist die Abdeckung an ihrer der Längsnut zugewandten Unterseite mit einer Aufnahme für die Maßverkörperung versehen. Diese Aufnahme ist vorzugsweise derart ausgebildet, dass die Maßverkörperung in Richtungen quer zum Schienenkörper einwandfrei positioniert ist. Die Maßverkörperung ist demzufolge einwandfrei in der Aufnahme gehalten, so dass auch ein einwandfreies Messen gewährleistet ist.The cover is convenient at their the longitudinal groove facing underside with a receptacle for the measuring standard. This recording is preferably designed such that the material measure is transverse in directions to the rail body is properly positioned. The measuring standard is therefore flawless kept in the recording, so that a perfect measurement guaranteed is.
Die Maßverkörperung kann bei der erfindungsgemäßen Führungsschiene lose in den Schienenkörper eingelegt werden. Sie erhält ihre einwandfreie Positionierung durch die an der Abdeckung vorgesehenen Aufnahme.The material measure can be in the guide rail according to the invention loose in the rail body be inserted. she receives their correct positioning by the provided on the cover Admission.
Nachstehend wird die Erfindung anhand eines in einer Figur dargestellten Ausführungsbeispieles näher erläutert.The present invention will be explained below of an embodiment shown in a figure.
