Description

Der Gegenstand der Erfindung bezieht sich auf eine Zielmarke, die für ein optisches Ausrichten und Ausfluchten von Maschinenteilen, insbesondere von Maschinenwellen und Wellenlagern, bestimmt ist, wobei die Zentrierung durch einen am Zielmarkenträger angebrachten Zylinder oder Kegel erfolgt. Bekannte Ausführungen haben den Nachteil, daß sie an den Wellenenden, die. zwar normalerweise eine Zentrierung aufweisen, nicht ohne zusätzliche Hilfsmittel angebracht werden können. The object of the invention relates to a target that for the optical alignment and alignment of machine parts, in particular of Machine shafts and shaft bearings, the centering being determined by a The cylinder or cone attached to the target carrier is carried out. Known versions have the disadvantage that they are at the shaft ends that. usually a centering cannot be attached without additional aids.

Auch für die Aufnahme in Lagern bedürfen. sie vielfach einer besonderen Hilfswelle, die entweder mit einem Innenzylinder oder einem Innenkegel versehen sein muß.Also required for inclusion in camps. she is often a special one Auxiliary shaft provided with either an inner cylinder or an inner cone have to be.

Die Zentrierung der Zielmarke läßt sich jedoch wesentlich einfacher und schneller in der Zentrierung der Welle oder der Hilfswelle durchführen, wenn nach der Erfindung det Zielmarkenträger mit einem Magneten ausgerüstet ist, der den Zielmarkenträger an dem auszurichten den Gegenstand, nämlich an der Welle oder der Hilfswelle, festhält, wobei zur selbsttätigen Zentrierung der Zielmarke ein in der Zielachse verschiebbarer und unter Federdriick stehender Zentrierkörper dient In vorteilhafter Weise wird ein kegeliger oder kugelförmiger Zentrierkörper benutzt, der auf einem Zentrierzapfen. verschiebbar sitzt. Ist der Zentrierkörper auswechselbar angeordnet, so kann er bequem der jeweiligen Große der an der Welle oder Hilfswelle vorhandenen Zentrierbohrung angepaßt verden. The centering of the target mark can, however, be much easier and perform faster in the centering of the shaft or the auxiliary shaft, if according to the invention det target mark carrier is equipped with a magnet that the target mark carrier to align the object, namely on the shaft or the auxiliary shaft, with a self-centering of the target mark The centering body, which can be moved in the target axis and is under spring pressure, is used A conical or spherical centering body is advantageously used, the one on a centering pin. slidably seated. Is the centering body replaceable arranged, so he can comfortably the respective size of the on the shaft or auxiliary shaft adapted to the existing centering hole.

Eine beispielsweise Ausführungsform des Gegenstandes der Erfindung ist in der Zeichnung teilweise im Schnitt dargestellt. An example embodiment of the subject matter of the invention is shown partially in section in the drawing.

An einem Zielmarkenträger I sitzt ein Zentrierzapfen 2, dessen Achse senkrecht auf der Auflagefläche des Trägers I steht un.d auf dem eine unter dem Druck einer Schraubenfeder 4 stehende Kugel 5 verschiebbar angeordnet ist. Diese Kugel ist durch den Kopf einer Schraube 6 gegen Herabgleiten ge sichert. An; dem Träger I ist eine eine Zielmarke 7 tragende Glasplatte 8 in einer Fassung 9 befestigt, die durch ein Deckglas 10 geschützt ist. Die Fassung 9 ist mittels vier im gleichen Abstand voneinander angeordneten Schrauben 14 verstellbar am Träger, um die Zielmarke 7 so einstellen zu können, daß sie in der Achse des Zentrierzapfens 2 liegt. A centering pin 2 and its axis are seated on a target carrier I perpendicular to the support surface of the carrier I is un.d on the one below the Pressure of a coil spring 4 standing ball 5 is slidably arranged. These Ball is secured against sliding ge by the head of a screw 6. At; to the Carrier I is a glass plate 8 carrying a target 7 attached in a mount 9, which is protected by a cover glass 10. The version 9 is by means of four in the same Spacing of one another arranged screws 14 adjustable on the carrier to the target mark 7 so that it lies in the axis of the centering pin 2.

Mittels eines am Träger angeordneten Magneten 11 läßt sich die Zielmarke an einer Welle 12 oder einer Hilfswelle ansetzen und wird durch die Kugel, die in eine an der Welle 12 vorgesehene Zentrierbohrung I3 gedrückt wird, selbsttätig zentriert. An Stelle eines Dauermagneten kann. auch ein Elektromagnet verwendet werden.The target mark can be set by means of a magnet 11 arranged on the carrier on a shaft 12 or an auxiliary shaft and is supported by the ball in a centering hole I3 provided on the shaft 12 is pressed, automatically centered. Instead of a permanent magnet. an electromagnet can also be used.

PATENTANSPRVCHE: I. Zielmarke mit Zentrierkörper, die für ein optisches Ausrichten und Ausfluchten von Maschinenteilen, insbesondere von Maschinenwellen und Wellenlagern, bestimmt ist dadurch gekennzeichnet, daß der Zielmarkenträger mit einem Magnet ausgerüstet ist, der den. Zielmarkenträger an dem auszurichtenden Gegen stand festhält, während die Zielmarke durch einen in der Zielachse verschiebbaren und unter Federdruck stehenden Zentrierkörper in der Zentrierbohrung der Welle selbsttätig zentriert wird. PATENT CLAIM: I. Target mark with centering body for an optical Alignment and alignment of machine parts, in particular machine shafts and shaft bearings, is characterized in that the target mark carrier is equipped with a magnet that the. Target carrier on the to be aligned Object was held while the target mark by a movable in the target axis and spring-loaded centering body in the centering bore of the shaft automatically is centered.
