Marking and dimension transfer device

The innovation relates to a marking and measurement transfer device, preferably for sections over 1 nu length, for use on a large ruler.

j Up to now, this work, for example in the case of road

work in the field of aerospace, normal rulers are used, but their dimensional transfers have very high tolerances were subjected, be it due to eye defects, parallaxes, reading errors, etc. In particular those below a millimeter Intermediate values were subject to the estimate. The high accuracy of the scales has not yet been exploited.

Oversized calipers with a measuring length of over 1000 mm have already become known, but these are only custom-made are available and are therefore very expensive. Their handling is also very cumbersome and often carried out by one person alone not feasible. These calipers cannot be used universally either.

The innovation has set itself the task of eliminating these disadvantages and creating a marking and dimension transmission device, with which especially large sections or diameters are measured and transferred to workpieces or drawings with high measuring accuracy or can be controlled.

This object is achieved in that a ruler guide part a clamping part and a measuring carrier part are assigned and all parts together form a single structural unit, the Ruler guide part is provided with a roller carrier and a knurled roller for fine adjustment and the clamping part for parallel holding of the device picks up spring pressure arrangements and clamping arrangements with the ruler.

In an embodiment of the innovation it is proposed that the clamping bolt in the clamping part of the device with an eccentric part is provided and is attached to the clamping part by means of a wing nut. In addition, the pressure bolt is ground spherically at its end facing the guide ruler or with inclined surfaces is provided.

Furthermore, the innovation provides that the measuring carrier part has a magnifying glass attachment, markings for parallel adjustment and adjustment has rulers with vernier scales on the axis cross, as well as on the guide ruler side. The side part of the measuring device part are innovatively designed as measuring and line edges, with dii ^ guide ruler a parallel line edge has a precisely tolerated length with a measure from the decimal system.

The innovation is described using an exemplary embodiment and drawn, so that further advantages and measures can be derived from this. Show it:

The innovation according to the marking and measurement transmission device for large sections is shown in Figs. 1 to 3 in a Ausfühi ungsbeispiel illustrated, for the sake of clarity in Figures 1 and 3 of the roller carrier 13 and the knurled roller l4, as well the wing nut 17 has been omitted. To work with the new device, two pieces are required, which are adjusted and clamped on the ruler 100 according to the distance to be measured at their beginning and end. By means of a Measuring magnifier, not shown, which is fastened in the magnifying glass attachment 21, and one of the vernier scales of the rulers 24, 25 of the measuring elements 12, the gauges are meticulously on the initial and

End point of the measuring section set. The exact parallel position can be seen on the markings 22 and the setting on the Read off the axis cross from the markings 23 on the scale part 12. The device is expediently designed so that the desired route with the inner edge or 26 of the two devices facing it, or with the outer edge 26 or 27 is measured, the latter is mainly recommended for the transfer of dimensions from large circular or hole diameters. To the precise fine adjustment is used by the knurled roller l4, which is arranged in a roller carrier 13 on the ruler guide part 10 and according to the illustrated embodiment, through a bore with the ruler 100, on which it rolls, comes into contact. This knurled roller l4 can be made of both metal and plastic being. Once the fine adjustment has been made, the devices can be fixed by means of a clamping arrangement 16, 17, 18, 19, 20. The. The clamping arrangement consists of a clamping bolt l6 with an eccentric part 20, which is in operative connection with a clamping bolt l8 stands, and a 7 pound wing nut together holding the tensioning bolt 16 connects to the so-called clamping part 11. The latter is provided with spring pressure assemblies 15, which above all a tilting of the Prevent the device from moving on the ruler. Once the setting has been made, the new marking and measurement transmission devices by means of the wing screw 17 the pressure pin l8 clamped to the ruler 100. This pressure bolt l8 is ground spherically at its end facing the ruler 100, whereby a punctiform abutment is achieved, or the end is provided with inclined surfaces, whereby a line or a surface contact occurs. The latter version should generally be the most recommendable because of changes in shape largely avoided on the guide ruler. It proves to be advantageous if the one lying parallel to the ruler 100 The line edge 28 of the measurement carrier part 12 has a precisely tolerated length with a dimension - for example 10 cm - from the decimal system.
