Description

Anreißapparat mit einer gleichzeitig als Anzeiger dienenden Nadel. Zum Anreißen zentrischer Flächen von Werkteilen, z. B. Scheiben, Maschinengehäusen u. dgl., sind die seither benutzten Anreißer bzw. Anreißapparate nicht geeignet. Um diesen Zweck zu erreichen, ist gemäß der Erfindung die Anreißnadel als Kniehebel mit gegeneinander verstellbaren Schenkeln ausgebildet.Scriber with a needle that also serves as an indicator. For marking out central areas of work parts, e.g. B. discs, machine housings and the like, the scribers or scribing devices that have been used since then are not suitable. In order to achieve this purpose, according to the invention, the scriber is a toggle lever formed with mutually adjustable legs.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung veranschaulicht.An exemplary embodiment of the invention is illustrated in the drawing.

Fig. i zeigt eine vordere Ansicht des Anreißapparates; Fig. z ist eine Seitenansicht und Fig.3 eine Draufsicht.Fig. I shows a front view of the scribing apparatus; Fig. Z is a side view and FIG. 3 a plan view.

Zwischen den Schenkeln i und 2 eines Stativs 3, das an einem winkelig gestalteten Fuße q. befestigt ist, ist auf einem Bolzen 5 ein Kniehebel 6, 7 gelagert. Der Schenkel 6 dieses Kniehebels trägt die Anreißnadel8, die nach Lösen einer Stellschraube g verstellbar ist, während der Schenkel ? mit seiner Verlängerung io auf die Skala eines mit der Drehachse des Kniehebels 6, 7 korrespondierenden bogenförmigen Lineals ii weist. Zum Anreißen zentrischer oder zentrisch angeordneter Werkteile müssen die Differenzen zwischen der ebenen Anreißplatte und den Kreisabschnitten der anzureißenden zentrischen Flächen (s. die punktiert angegebenen Bogen in Fig. i) vor der Benutzung des Apparates ausgeglichen werden. Dies geschieht durch eine Veränderung des Winkels zwischen den Schenkeln 6 und 7 des Kniehebels, und zwar in bekannter Weise durch Lösen einer Stellschraube 13, während zum Festhalten des Kniehebels 6, 7 zwischen den Schenkeln i und 2 des Stativs 3 in bekannter Weise eine Flügelschraube 1q. dient. Das Einstellen der Anreißnadel8 auf bestimmte Abstände geschieht in bekannter Weise nach Lösen der Flügelschraube =q. dadurch, daß die Pinne iz auf den erforderlichen Strich der Skala des Lineals i1 eingestellt und die Flügelschraube 14 wieder angezogen wird.Between the legs i and 2 of a tripod 3, which is angled at one designed foot q. is attached, a toggle lever 6, 7 is mounted on a bolt 5. The leg 6 of this toggle lever carries the scriber 8, which after loosening a set screw g is adjustable while the leg? with its extension io on the scale an arcuate ruler corresponding to the axis of rotation of the toggle lever 6, 7 ii has. For marking centric or centric work parts, the differences between the flat scribing plate and the segments of the circle to be scribed centric surfaces (see the dotted arc in Fig. i) before use of the apparatus can be compensated. This is done by changing the angle between the legs 6 and 7 of the toggle, in a known manner by Loosening a set screw 13 while holding the toggle lever 6, 7 between the legs i and 2 of the stand 3 in a known manner a wing screw 1q. serves. The setting of the scriber8 to certain distances is done in a known manner after loosening the wing screw = q. in that the tiller iz on the required Line on the scale of the ruler i1 is set and the wing screw 14 is tightened again will.

Das Anreißen mittels der Nadel 8 erfolgt durch Bewegung des Fußes q. über die Oberfläche des zentrischen Werkteils.The marking by means of the needle 8 is carried out by moving the foot q. over the surface of the centric part of the work.
