The present invention relates to a tool holder for machine tools of all Type and consists in the fact that the working steel in the steel holder can be rotated in the latter stored key by means of an eccentric slide in a groove of the working steel mounted pin can be adjusted, the size of the displacement by any The measuring device can be determined or read from a scale and the key or the working steel after setting by pressure screws, nuts or the like. can be determined.

In the drawing the invention is shown represents, namely shows:

Fig. Ia a section through a steel holder, Fig. 1b a side view of the same,

Fig. Ic a section through another embodiment,
Fig. Ι the front view,

Fig. 2 is a side view of a steel holder with pendulum suspended in a known manner, steels swinging around fixed points, adjustable in height, which are and reverse gears of the machine work

Fig. 3 illustrates the plan view of an embodiment of the pointer mechanism.

FIG. 4 shows an embodiment of FIG. 4 arranged on a planer or turning tool holder Invention in section.

Fig. 5 shows the embodiment suitable for a drill head, while

6 shows a drill head with the invention in side view and
Fig. 7 shows the same in front view.

The working steel b, which can be moved in the steel holder, is provided with grooves i . A key g is rotatably mounted in the steel holder. This key has an eccentrically mounted pin h, which engages in the groove i of the steel b and, when the key is turned, the adjustment of the working steel in any, precisely determinable. Length causes.

The key g can be stored directly in the steel holder (Fig. Ia and ib) or in a hollow pin d of the steel holder (Fig. 1 and 2) or in a sleeve (Fig. Ic) or in a drill head (Fig. 5 to 7) be.

The embodiments shown in FIGS can of course be designed differently without changing the essence of the invention.

Fig. Ι and 2 show the invention on a steel holder, the holder around fixed points in a housing are suspended swinging, which allow in a known manner; that the. Machine tool works forward and backward.

The holders α for the steels b are swinging around fixed pins c, d in the housing / which can be closed by cover e. The key required for precise setting g. is provided with a pin h arranged eccentrically on a head. The pin h engages in corresponding grooves i of the steel b and here, too, causes the steel to be adjusted to any precisely determinable height when the key is turned. The key g is stored in the hollow pin d of the steel holder α. The size of the

Displacement can be determined by any measuring device. This measuring device can be arranged on the steel holder. An embodiment of the same is set up as follows: A pointer ο is connected to the key, while a disk m provided with a scale η is attached to the pin d. When the key g is turned, the pointer ο ίο on the disk m also turns. The pointer ο can be clamped onto the disk m by nut p, so that the chip pressure is overcome and the wrench or working tool does not move automatically If a further adjustment becomes necessary, only the square q needs to be turned with a key, whereby the pointer 0 on the scale η is adjusted, but stops as soon as the square stops turning. The setting of the pointer on the scale can be done extremely precisely. The pointer can be provided with different marks, which enable the exact setting to the smallest part of a millimeter. A so-called print head k, on which the pin h is seated, is provided on the key g. This printhead rests against a threaded sleeve I of part m. The sleeve is screwed into the hollow pin d and rotates with the same or sits in the steel holder. If the nut p is tightened, the printhead is pressed against the sleeve I and is here completely or only in such a way determined; that the chip pressure is overcome and the square q needs to be turned for the purpose of further adjustment. In order not to always have to remove the sleeve I when changing the steel for the purpose of sharpening, the printhead k is flat. The sleeve I has grooves l \ which continue wholly or partially through it, so that the print head can be pulled out completely (Fig. Ia) or partially (Fig. 1C, dotted) through the grooves if the position is suitable, whereupon the steel can also be conveniently pulled out can be removed from the holder. Fig. 4 shows the invention applied to a planer or turning tool holder. The steel b can be moved in the holder u and is provided with grooves i. An eye u1 is provided on the holder u, in which the pressure screw s can be adjusted by means of a thread. In the pressure screw s, which corresponds to the sleeve I, the key g rotates with the print head k, on which the pin h sits, which moves in grooves i. The angular head γ, on which the scale η can be provided, is arranged on the pressure screw. As already described, the pointer 0, which is firmly connected to the key g and which can be clamped on the scale for the purpose already described, by the nut p screwed onto the key g rotates on the latter. The printhead can be partially or completely clamped by the square r. The steel is adjusted by means of a square q using a key. If the intention is to work on wavy surfaces with the steel or to rotate the shape, a lever t is attached to the square and slides along a template, so that an inevitable automatic adjustment of the steel takes place according to the template. In this way, any number of different shapes can be planed, especially the machining of the same parts is possible at any time without difficulty, since the worker does not need to make a time-consuming adjustment of the different thicknesses. 5 to 7 show the device in a view arranged on drill heads. The setup is the same as described above. Even with drill heads, the device has the great advantage that the working steel is inevitably adjusted in its height, so that the time-consuming adjustment of the steel is eliminated. Ρλτκ nt claims: 1. Tool holder with steels adjustable by eccentrically mounted pins, characterized in that a key (g) provided with an eccentric pin is rotatably mounted in the tool 95 '■ holder, which with pin (h) in grooves (i) of the working steel (b ) engages and causes an adjustment of the working tool joo in the axial direction during rotation, the size of the adjustment being measured by any measuring device and the key or the working tool being wholly or partially determined by nuts, pressure screws or the like. 2. Tool holder according to claim 1, characterized in that the key (g) is mounted in the hollow pin (d) of the steel holder swingingly suspended in a housing (f) and swings with the steel holder. 3. Tool holder according to claim 1, characterized in that for the purpose of easier replaceability of the steel, the head (k) of the key (g) is oval or flat and the latter is mounted in a sleeve (I) screwed into the tool holder or the hollow pin (d) is, which carries grooves, so that when the head is in a suitable position, the key can be wholly or partially withdrawn from the holder can without the need to unscrew the sleeve. 4. Tool holder according to claim i, characterized in that the key is mounted for the purpose of use in planing or turning tool holders or in a drill head in a pressure screw (s) through which the locking of the key causes against rotation and thus that of the working tool against displacement can be. 5. Embodiment of the tool holder according to claim 1, characterized in that the adjustment of the steel (b) by means of the key and the pin running in a groove is carried out by a lever connected to the key which slides along a template, so that undulating surfaces and any shape can be processed with the device 1 sheet of drawings,
