Device for attaching measuring sticks to the angle piece of a drawing head

The invention relates to devices for attaching measuring rods at the elbow of the drawing head of drawing machines.

Devices for attaching measuring rods to the angle piece of the drawing head are known. You fixtures contain a bar attached to the character measuring bar, which is beveled on one of its long sides. A hat is provided in the elbow through which the drawing rods are attached to the drawing head. In this groove the bar operated on the character measuring rod btf is arranged. Hold down the character measuring rod β in the length of the angle piece by means of the one that acts as a wedge. Lead edge bevel (see, for example, the advertising font for drawing machines "Junior" from Kuhlmann BHD).

This device ensures only one fixed position the character measuring rods in the groove of the elbow and allows it does not, the scaling points of the mutually perpendicular measuring rods to unite.

In addition, there are devices for attaching character measuring sticks known by wedge-shaped inserts with screw terminals. Such devices are complicated to manufacture and have clamping parts protruding from the surface of the elbow, which interfere with the designer's work.

The invention is based on the object of providing a device for To develop attachment of measuring rods that make it possible to to hold the position of the measuring rods in any position and that is simple to manufacture and easy to use is.

This object was achieved in that the device for Attachment of measuring rods to the angle piece of a drawing head, which contains a bar which is rigidly seated on the measuring rod and which is fastened in a corresponding groove in the angle piece is, erfindungsgeaäß the attachment of the bar in the corresponding groove of the angle piece by a curved leaf spring, which is arranged spread between the bottom of the groove and the bar, takes place.

The leaf spring is advantageous with one end on the bar attached. ·

Such an attachment prevents when pulling the measuring stick the spring falling out of the elbow.

The device designed according to the invention for attaching measuring rods in the angle piece of the drawing head ensures with any position of the measuring rods a reliable retention of the same in the groove of the angle piece is easy in manufacturing and easy to use.

In the following the invention is based on the description of a Embodiment and the accompanying drawings explained in more detail. It shows

Fig. Λ an overall view of the device according to the invention for attaching measuring rods to the angle piece of a Z eichenma machine;

FIG. 2 shows a section along II - II of FIG. 1;

3 shows a section according to IH-III of FIG. 1. M

An angle piece 1 (Fig. 1), the two mutually perpendicular measuring rods 2 is rigidly connected to a drawing head 3. On the character measuring rods 2 is by means of screws 4, 5 a Fastened bar 6, which has a "dovetail shape" in cross section.

In the elbow 1, a groove 7 is made for the arrangement of the bar 6. The height of the groove 7 is slightly greater than that of the

Bar 6. Sitting between the bottom of the groove 7 and the bar 6 a curved leaf spring 8. The leaf spring 8 is arranged between the bottom of the groove 7 and the strip 6 so as to be spread. The one The end of this spring is rigidly attached to the measuring rod 2 together with the bar 6 by the screw 4-, the other end is exposed. The measuring rods 2 are held in place in the angle piece 1 thanks to the elastic properties of the leaf spring 8.

In this way, the character measuring rods 2 are constantly by a constant force pinched, making them in any position, especially in one in which the zero strokes of the mutually perpendicular rods coincide, can be adjusted.

In the working position of the measuring rods 2, the bar 6 is completely sunk into the groove 7, whereby the outer surface of the angle piece, as can be seen from Fig. Λ, can be made quite smooth.

To adjust the angle of the measuring rod 2 in the angle piece 1, the measuring rod 2 with bar 6 is advanced out of the groove 7 of the angle piece 1 so that the screw 5 is outside (the bar). Then the screw 5 is loosened and the angle adjustment is carried out in the usual way. After setting, slide the measuring rod 2 in the groove 7 of the angle piece Λ to the required position.
