Description

Meßmaschine mit zwei Portalen für Werkstücke kleinerer und mittlerer Abmessungen Die Erfindung betrifft eine Meßmaschine mit zwei Portalen für Werkstücke kleinerer und mittlerer Abmessungen wie Motorblöcke, Getriebe- und Pumpengehäuse Die Meßmaschinenmit zwei Portalen sind zur Erzielung großer Meßgenauigkeiten besser geeignet als Meßmaschinen mit Auslegearm oder solche mit nur einem Portal, auf dem der Querschlitten läuft, insbesondere da bei ihnen nicht die Verbiegungen auftreten wie bei auskragenden Armen und nicht Verkantungen und Verdrehungen in einer Größenordnung wie bei den Meßmaschinen mit nur einem Portal Bei Meßmaschinen mit zwei Portalen zur M.essung größerer Werkstücke wie Karosserieteile, bei denen der die Maschine Bedienende in den Raum zwischen den Ständern der Portale treten und unmittelbar an das Werkstück herantreten kann, wirkt sich diese Konstruktion nicht nachteilig auf die Bedienung der Maschine aus Bei den Meßmaschinen mit zwei Portalen für Werkstücke kleinerer und mittlerer Abmessungen, bei denen der Bedienende aber nicht zwischen die Ständer der Portale treten, sondern an der Maschine stehend nur durch seine Arme an das Werkstück heranreichen kann, stellen die vier massiven Ständer der Portale ein beachtliches Hindernis für den Zugang zum Werkstück dar Der Erfindung liegt die Aufgabe zugrunde, eine Meßmaschine mit zwei Portalen für Werkstücke kleinerer und mittlerer Abmessungen zu schaffen, die sich zur Erzielung großer Meßgenauigkeit eignet und diese Eigenschaft verbindet mit der besseren Zugänglichkeit zum Werkstück, wie sie bisher nur bei für geringere Meßgenauigkeit geeigneten Maschinen zu finden ist. Measuring machine with two portals for workpieces of small and medium size Dimensions The invention relates to a measuring machine with two portals for workpieces smaller and medium-sized dimensions such as engine blocks, gear boxes and pump housings The measuring machines with two portals are better for achieving high measuring accuracies suitable as measuring machines with an extension arm or those with only one portal on which the cross slide runs, especially since they do not bend as with cantilevered arms and not canting and twisting of the same order of magnitude as with measuring machines with only one portal. With measuring machines with two portals for the measurement of larger workpieces such as body parts, where the machine Operators step into the space between the posts of the portals and immediately can approach the workpiece, this construction is not disadvantageous on the operation of the machine. With the measuring machines with two portals for workpieces Smaller and medium-sized dimensions, but where the operator does not choose between the uprights of the portals step, but standing at the machine only through his Arms can reach the workpiece, the four massive pillars of the portals The invention is a significant obstacle to access to the workpiece the task is based on a measuring machine with two portals for smaller workpieces and to create medium dimensions, which can be used to achieve high measurement accuracy and this property combines with better accessibility to the workpiece, as it has so far only been found in machines suitable for lower measuring accuracy is.

Diese Aufgabe wird erfindungsgemäß durch eine Meßmaschine gelöst, die gekennzeichnet ist durch ein vorzugsweise motorisch verschiebliches, rechtwinklig zum mit dem Maschinenbett starr verbundenen Portal angeordnetes, nur einen Ständer aufweisendes, den Längsschlitten bildendes Portal, dessen mit der Führungsschiene für den Querschlitten versehener waagerechter Portal arm am freien Ende in einer im waagerechten Querriegel des starrer Portals angebrachten Führungsschiene geführt ist, wobei vom Ständer des verschieblichen Portals unterhalb der Werkzeugaufspannplatte ein durch einen Durchbruch der- angrenzenden Wand des Maschinenbetts hindurchgeführter, bis etwa zur Mittellinie der Maschine ragender Arm abzweigt, an dessen Ende der zu der dort befindlichen Meßeinrichtung zugehörige Meßwertgeber angebracht ist.According to the invention, this object is achieved by a measuring machine, which is characterized by a preferably motor-driven, right-angled to the portal rigidly connected to the machine bed, only one column having, the longitudinal slide forming portal, whose with the guide rail for the cross slide provided horizontal portal arm at the free end in one guided in the horizontal crossbar of the rigid portal is, from the stand of the movable portal below the tool mounting plate a through a breakthrough in the adjacent wall of the machine bed, up to about the center line of the machine branches off the arm, at the end of which the associated transducer is attached to the measuring device located there.

Allein schon die Verringerung der Zahl der Ständer von vier auf drei bei Beibehaltung eines starr mit dem Maschinenbett verbundenen Portals hat schon die Verbesserung des Zugangs zum Werkstück ohne Einbuße an erzielbarer Meßgenauigkeit zur Folge.Simply reducing the number of stands from four to three while maintaining a portal rigidly connected to the machine bed has already the improvement of the access to the workpiece without loss of the achievable measuring accuracy result.

Eine Steigerung an erzielbarer Meßgenauigkeit wird darüber hinaus noch dadurch erreicht, daß die Meßeinrichtung von der Umfassung des Maschinenbetts in deren Zentrum verlegt ist, da bei dieser Anordnung bei Meßfehlern infolge waagerechter Verdrehungen des Maschinengestells der Faktor Abstand des aus Verdrehung des Gestells und Abstand des Meßpunktes von der Meßeinrichtung gebildeten, den Meßfehler ergebenden Produkts nur die halbe Größe erreichen kann wie bei der Anordnung der Meßeinrichtung an der Umfassung des Maschinenbetts.In addition, there is an increase in the achievable measurement accuracy still achieved in that the measuring device from the enclosure of the machine bed is relocated in the center, since with this arrangement in the event of measurement errors due to horizontal Rotation of the machine frame is the factor of the distance from the rotation of the frame and the distance of the measuring point from the measuring device, which results in the measuring error Product can only reach half the size as with the arrangement of the measuring device on the enclosure of the machine bed.
