Definitions
- the invention relates to a device for compensating for play on a circular disk-shaped device carrier to be inserted into a circular opening.
- Device carriers of the type mentioned which are used in measuring devices, must be able to be aligned with another device part with as little play as possible. This applies in particular to equipment carriers for holding standard sample changers, rotary and beam sample changers in X-ray diffractometers, which require very precise alignment in the beam path. This was previously achieved by inserting the circular disk-shaped device carrier with a high-quality, tight fit into the circular opening of a base plate and fastening it there with screws; reproducible removal and installation of the device carrier was not possible without repeated, complex adjustment assembly.
- the circular disc-shaped device carrier can be manufactured for normal fit (sliding fit), whereby only the edges of the three projections serve as the fitting surfaces.
- the resilient section with the projection can be adjusted radially, so that the device carrier is fixed in the opening without play is.
- the circular disc-shaped device carrier 1 is provided on its circumference with three projections 2, 2 'and 2 ⁇ at angular intervals of 120 °.
- the projections 2, 2 ', 2 ⁇ are arch-shaped, about 0.5 to 1 mm high and each extend over a length of 8 to 10 of the circumference of the circular disc-shaped device carrier 1.
- Their edge surfaces form the mating surfaces that are with the inner surface 3rd the circular opening 4 form a fit.
- the projection 2 is arranged on a section 5 which is resilient in the radial direction and which is formed from an arc-shaped slot 6 and two slots 7 which extend from the circumference of the device carrier 1 in the radial direction and are then directed tangentially toward one another.
- a wedge or truncated cone-shaped pressure piece 8 is attached, which is adjustable parallel to the central axis of the device carrier 1 with the aid of a screw 9. By actuating the screw 9, a play compensation of the fit in the direction of a diameter is possible.
- the circular disk-shaped device carrier 1 is provided with a protruding edge 10 with three threaded holes 11 parallel to the central axis, which, after making the play compensation, serve to fasten the device carrier 1 by means of screws 12 on the edge of the circular opening 4.
- a washer 13 under the resilient area 5 prevents bending and tilting when compensating for play.

Description
Die Erfindung bezieht sich auf eine Vorrichtung zum Spielausgleich an einem in eine kreisförmige Öffnung einzusetzenden kreisscheibenförmigen Geräteträger.The invention relates to a device for compensating for play on a circular disk-shaped device carrier to be inserted into a circular opening.
Geräteträger der genannten Art, die in Meßgeräten eingesetzt sind, müssen möglichst spielfrei auf ein anderes Geräteteil ausrichtbar sein. Das gilt insbesondere für Geräteträger zur Aufnahme von Standard-Probenwechslern, Dreh- und Durchstrahl-Probenwechslern in Röntgendiffraktometern, die eine sehr genaue Ausrichtung im Strahlengang erfordern.
Das wurde bisher dadurch erreicht, daß der kreisscheibenförmige Geräteträger mit einer hochwertigen engen Passung in die kreisförmige Öffnung einer Grundplatte eingefügt und dort mittels Schrauben befestigt wurde, reproduzierbares Aus- und Einbauen des Geräteträgers war ohne wiederholte, aufwendige Justiermontage nicht möglich.Device carriers of the type mentioned, which are used in measuring devices, must be able to be aligned with another device part with as little play as possible. This applies in particular to equipment carriers for holding standard sample changers, rotary and beam sample changers in X-ray diffractometers, which require very precise alignment in the beam path.
This was previously achieved by inserting the circular disk-shaped device carrier with a high-quality, tight fit into the circular opening of a base plate and fastening it there with screws; reproducible removal and installation of the device carrier was not possible without repeated, complex adjustment assembly.
Es besteht demgemäß die Aufgabe, einen Geräteträger mit normaler, leicht herstellbarer und handhabbarer Passung zu schaffen, der eine Vorrichtung zum Ausgleich des mechanischen Spiels zwischen Geräteträger und Grundplatte aufweist.Accordingly, there is the task of creating a device carrier with a normal, easily manufactured and manageable fit, which has a device for compensating for the mechanical play between the device carrier and the base plate.
Eine Lösung der Aufgabe wird in einer Vorrichtung mit den Merkmalen des Anspruchs 1 gesehen.A solution to the problem is seen in a device with the features of
Der kreisscheibenförmige Geräteträger kann für normale Passung (Gleitsitz) hergestellt werden, wobei als Passungsflächen lediglich die Ränder der drei Vorsprünge dienen. Zum Spielausgleich kann der federnde Abschnitt mit dem Vorsprung radial verstellt werden, so daß der Geräteträger in der Öffnung spielfrei festgelegt ist.The circular disc-shaped device carrier can be manufactured for normal fit (sliding fit), whereby only the edges of the three projections serve as the fitting surfaces. To compensate for play, the resilient section with the projection can be adjusted radially, so that the device carrier is fixed in the opening without play is.
Zur Erläuterung der Erfindung ist in den Figuren 1 und 2 ein Ausführungsbeispiel in zwei Ansichten dargestellt und im folgenden beschrieben.To explain the invention, an embodiment is shown in two views in Figures 1 and 2 and described below.
Der kreisscheibenförmige Geräteträger 1 ist an seinem Umfang mit drei Vorsprüngen 2, 2′ und 2˝ in Winkelabständen von jeweils 120° versehen.
Die Vorsprünge 2, 2′, 2˝ sind bogenförmig begrenzt, etwa 0,5 bis 1 mm hoch und erstrecken sich jeweils über eine Länge von 8 bis 10 des Umfangs des kreisscheibenförmigen Geräteträgers 1. Ihre Randflächen bilden die Paßflächen, die mit der Innenfläche 3 der kreisförmigen Öffnung 4 eine Passung bilden.The circular disc-

Der Vorsprung 2 ist auf einem in radialer Richtung federnden Abschnitt 5 angeordnet, der aus einem kreisbogenförmigen Schlitz 6 und zwei vom Umfang des Geräteträgers 1 in radialer Richtung ausgehenden und dann tangential gegeneinander gerichteten Schlitzen 7 gebildet ist.
In dem kreisbogenförmigen Schlitz 6 ist ein keil- oder kegelstumpfförmiges Druckstück 8 angebracht, welches parallel zur Mittelachse des Geräteträgers 1 mit Hilfe einer Schraube 9 verstellbar ist. Durch Betätigen der Schraube 9 ist ein Spielausgleich der Passung in Richtung eines Durchmessers möglich.The

Der kreisscheibenförmige Geräteträger 1 ist mit einem überstehenden Rand 10 mit drei zur Mittelachse parallelen Gewindelöchern 11 versehen, die nach Vornahme des Spielausgleichs zur Befestigung des Geräteträgers 1 mittels Schrauben 12 am Rande der kreisförmigen Öffnung 4 dienen.
Eine Unterlegscheibe 13 unter dem federnden Bereich 5 verhindert Verbiegen und Verkanten beim Spielausgleich.The circular disk-
