In such a known measuring device, there is always a return to the zero position. Due to the fact that the measuring element consists of two spreading jaws and one conical, that with the positioning of the vision needle according to the invention, the value, which can only be moved vertically from the spreading jaws, is held on a display device, namely the measuring device, can transfer workpieces that are in the measuring head. The measuring element is clamped in a supporting column connected to the lung on the measuring table, which is not connected to the measuring table without auxiliary means. Those that remain, are pressed down with the hand. The work stacks measuring according to the invention lie on a lifting table to be operated by means of the device according to the invention for holding the measuring element, hand lever, and are fed to the measuring probe, including the oil damping, absolutely maintenance-free by lifting the latter. and consists only of simple, relatively coarse dimensions In this known device, there is the disadvantage that parts.

Der Sokkel besitzt eine Föhrungssäule 4, in welcher die Tragesäule 5 verschiebbar und mittels eines Hebels 6 ein- und feststellbar ist. Die Tragesäule 5 hält einen kastenförmigen Tragekörper 7 mit dem aus Meßsonde 8 und Meßkopf 9 bestehenden Meßorgan. Mittels einer Klemme 10 kann dus Meßorgan vom Tragekörper 7 gelöst und in Richtung des Pfeiles 11 aus dem Tragekörper gezogen werden.«From a base 1 and a height-adjustable measuring table 3 to be operated by a lever 2. The base has a Föhrungssäule 4, in which the support column 5 is displaceable and adjustable and lockable by means of a lever 6. The support column 5 holds a box-shaped Support body 7 with the measuring element consisting of measuring probe 8 and measuring head 9. By means of a Terminal 10 can be detached from the support body 7 and in the direction of arrow 11 from the support body to be pulled.
Wie aus F i g. 2 hervorgeht, sind im kastenförmigen Tragekörper 7 zwei rechtwinkelig zueinander angeordnete, in der Art eines Parallelogramm-Gestänges ausgebildete Federblatthalterungen 12,13 angeordnet. Die Feiiertrtatthaiterung 12 besteht aus einer mit dem Tragekörper 7 verbundenen und somit ortsfesten Platte 12a, welche beidseitig Blattfedern 126 trägt Letztere Blattfedern sind derart angeordnet, daß sie über den Boden Ta des Tragdkörpers frei schwingen können. An ihren, der Einspanristelle gegenüberliegenden Enden sind die Blattfedern mit der Schwingplatte 12c verbunden, welche in RicMung des Pfeiles 14 schwingbeweglich gehalten ist. Die Schwingplatte 12c trägt wiederum die Halteplatte 13« der zweiten Federblatthalterung 13 mit den Blattfedern 13b und der Schwingplatte 13c,. welche in Richtung des Pfeiles 15 schwingbeweglich in den vorgenannten Blattfedern gehalten ist Eine Klemme 16 ist mit der Schwingplatte 13e verbunden und besitzt eine Bohrung 17 zur Aufnahme des Meßorgans. Im Boden Ta sowie im Deckel Tb des Tragkörpers befindet sich jeweils eine hinreichend weite Ausnehmung, derart, daß das Meßorgan einen genügend großen Spielraum besitzt Mit der Schwingplatte 13c ist fernerhin ein öldämpfer 19 verbunden, dessen Widerlager der Boden Ts des Tragekörpers ist.As shown in FIG. 2, two spring leaf holders 12, 13, which are arranged at right angles to one another and designed in the manner of a parallelogram linkage, are arranged in the box-shaped support body 7. The Feiiertrtatthaiterung 12 consists of a connected to the support body 7 and thus stationary plate 12a, which carries leaf springs 126 on both sides. The latter leaf springs are arranged such that they can swing freely over the bottom Ta of the support body. At their ends opposite the clamping point, the leaf springs are connected to the oscillating plate 12c, which is held in an oscillating manner in the direction of the arrow 14. The oscillating plate 12c in turn carries the holding plate 13 ″ of the second spring leaf holder 13 with the leaf springs 13b and the oscillating plate 13c. which is held in the aforementioned leaf springs such that it can oscillate in the direction of arrow 15. A clamp 16 is connected to the oscillating plate 13e and has a bore 17 for receiving the measuring element. In the bottom Ta as well as in the lid Tb of the supporting body, in each case there is a sufficiently wide recess, in such a way that the measuring element has a sufficiently large margin with the vibrating plate 13c, an oil damper 19 is henceforth connected, the abutment of the bottom Ts is of the carrying body.
Die Blattfedern 126 und 13/? sind, wie ersichtlich, mit Plattierungen 20 versehen, welche eine Verwindung der Gestänge gegeneinander verhindern. Die wirksame Federlänge ist hierbei so gehalten, daß bei den zu erwartenden Störkräften die Amplitude bei annähernd 1,5 mm liegt und bei relativ kldner Schwingungsfrequenz der öldämpfer 19 besonders wirkungsvoll ist.The leaf springs 126 and 13 /? are, as can be seen, with Plates 20 provided, which prevent twisting of the rods against each other. The effective The length of the spring is kept in such a way that the amplitude at approximately the expected disturbance forces 1.5 mm and at a relatively low oscillation frequency the oil damper 19 is particularly effective.
