Abstract
Längenmesseinrichtung mit einem Maßstab (21), der von einem Abtastkopf (22) abtastbar ist und mit Montagemitteln (30) zur lösbaren Ankopplung des Maßstabs (21) an die Führungsschiene (11) einer aus einer Führungsschiene (11) und einem Wagen (12) bestehenden Linearführung, die als eigenständige Baueinheit (10) mit einer Anbaufläche (14) an eine Montagefläche (100) einer Maschine anbringbar ist, wobei die Montagemittel (30) senkrecht zur Längsrichtung (X) der Führungsschiene (11) wirkende Anschlagflächen (31, 32) zur parallelen Ausrichtung des Maßstabs (21) längs der Führungsschiene (11) aufweisen, und die Montagemittel (30) in Längsrichtung der Führungsschiene (11) voneinander beabstandet angeordnet sind und die Bewegung des Wagens (12) in Längsrichtung (X) begrenzen, indem diese zum Umgreifen und zum Anschlagen der Anschlagflächen (31, 32) an Referenzflächen (15, 16) der Führungsschiene (11) außerhalb der Anbaufläche (14) ausgebildet sind, wobei die Referenzflächen (15, 16) die bei der Fertigung der Führungsschiene (11) zur Führung des Wagens (12) hochgenau bearbeiteten und homogen in Längsrichtung (X) verlaufenden äußeren Flächen sind und die von den Montagemitteln (30) umgriffene Referenzfläche (15) parallel zur Anbaufläche (14) verläuft und die Oberseite der Führungsschiene (11) bildet.Length measuring device with a scale (21) which can be scanned by a scanning head (22) and with mounting means (30) for detachably coupling the scale (21) to the guide rail (11) of a guide rail (11) and a carriage (12) existing linear guide, which is mountable as an independent unit (10) with a mounting surface (14) on a mounting surface (100) of a machine, wherein the mounting means (30) perpendicular to the longitudinal direction (X) of the guide rail (11) acting stop surfaces (31, 32 ) for parallel alignment of the scale (21) along the guide rail (11), and the mounting means (30) are spaced apart longitudinally of the guide rail (11) and limit movement of the carriage (12) in the longitudinal direction (X), by these for gripping and for striking the stop surfaces (31, 32) on reference surfaces (15, 16) of the guide rail (11) outside the mounting surface (14) are formed, wherein the Referenzflä Chen (15, 16) in the manufacture of the guide rail (11) for guiding the carriage (12) highly accurately machined and homogeneously in the longitudinal direction (X) extending outer surfaces and by the mounting means (30) encompassed reference surface (15) parallel to Attachment (14) extends and forms the top of the guide rail (11).
Description
Die Erfindung betrifft eine Längenmesseinrichtung gemäß dem Anspruch 1 und eine Linearführungseinheit mit dieser Längenmesseinrichtung gemäß dem Anspruch 9.The invention relates to a length measuring device according to
Bei Bearbeitungs- und Messmaschinen setzt sich vermehrt der Einsatz von vormontierten Führungseinheiten, bestehend aus einer gehärteten und geschliffenen Führungsschiene und einen daran über Rollen- oder Kugelelemente geführten Wagen durch. Dabei ist die Führungseinheit eine eigenständige Baueinheit in der Art, dass die Führungsschiene mit einer Anbaufläche an einem Bett einer Maschine und der Wagen an einem Schlitten dieser Maschine anbringbar ist.In machining and measuring machines, the use of preassembled guide units, consisting of a hardened and ground guide rail and a carriage guided over roller or ball elements, is increasingly prevalent. In this case, the guide unit is an independent unit in the way that the guide rail with a mounting surface on a bed of a machine and the car on a carriage of this machine can be attached.
Zur Messung der Relativlage des Wagens gegenüber der Führungsschiene ist es z. B. aus der
Der Erfindung liegt die Aufgabe zugrunde, eine Längenmesseinrichtung zur Verfügung zu stellen, die besonders einfach austauschbar und platzsparend an eine Führungsschiene einer Linearführungseinheit montiert werden kann. Dabei soll eine parallele Ausrichtung des Maßstabs der Längenmesseinrichtung längs der Führungsschiene einfach erreicht werden.The invention has for its object to provide a length measuring device available, which can be mounted very easily replaceable and space-saving on a guide rail of a linear guide unit. In this case, a parallel alignment of the scale of the length measuring device along the guide rail should be easily achieved.
Diese Aufgabe wird durch die Merkmale des Anspruchs 1 gelöst.This object is solved by the features of
In Anspruch 9 ist eine Linearführungseinheit mit einer derartigen Längenmesseinrichtung angegeben.In claim 9, a linear guide unit is specified with such a length measuring device.
