Es können 2 bis 6 bei 28 auf, welcher schwenkbar ist, um die auf die oder noch mehr Werkzeuge vorgesehen sein; so stellt Welle3 längs eines Bruchteils ihrer Außenfläche 31 Fig. 6 fünf Werkzeuge 34, 35, 36, 37, 38 dar, die einwirkenden Klemmstücke 29 und 30 einander zu wechselweise in Wirkung gebracht werden können.and the rear end of the lever in the direction of the 5 As already stated, the holder 1 of the arrow 26 (Fig. 1) can push upwards. The rear end of the volverkopfes in any suitable manner on a 27 of the locking lever 21 can be attached to any tool carrier slide, the front section of the handle 15, so that in the case shown in Fig. 2 you can use a thumb or forefinger of this handle used piece 32, which allows the cutting hand on this a trigger forming io edge of the tool before tightening through the end, so that the turret with screw 33 to bring the desired height, this hand can be rotated as soon as the lock - This type of fastening is incidentally excavated from the number lever from the groove, with which it is selected in the chen fastening types, which one is each engagement. according to the shape of the slide and the present case the machining of a workpiece a force 15 circumstances can invent. In all cases, which has a significant effect on the attachment of the turret head to the work tool, the shaft 3 of the turret tool carrier slide allows the free use of the rear l'es with the holder 1 even more effectively through the in tool in every moment of processing.
F i g. 2 locks shown firmly connected. Of course, the number of tools can be arbitrary. One of these locks has a helix to be selected as required. There can be 2 to 6 at 28, which is pivotable about the or more tools to be provided; Thus, along a fraction of its outer surface 31, FIG. 6, shaft 3 represents five tools 34, 35, 36, 37, 38, the acting clamping pieces 29 and 30 can be brought into action alternately.

Turret head for lathes. 25 As can be seen from the drawing, the holder is

In a known turret of this type, the turret 1 is fastened to the usual tool, the bolt carrying the tool carrier, by a carrier block of a lathe. A hole 2 formed in the shark claw can be coupled to the handle for rotation, ter 1, and receives the shaft 3, which is rotatably mounted in the bearings by pivoting the handle of these surfaces 4 and 5. Bolt axially displaced and thereby the claw 3 ° In the turret coupling, which is firmly connected to the shaft 3, is released; then the work head 3 'are radial bores 6, 7, 8 and 9 tool carriers formed by the handle into the desired position, which are each rotated 90 ° apart from one another. This design is complex, th radiuses at equal distances from the axis because they are arranged on the one hand a tension spring and on the other hand one of the shaft 3. Each hole takes claw coupling requires. In spite of this, your hand has a corresponding tool which, due to its use, is relatively cumbersome, since the fixed tension operation is attached, which is shown in FIG. 1 is shown for the tool arranged in the coupling or uncoupling of the tool carrier of the bore 7, in many cases it must be carried out repeatedly, ie for the tool that is ready to work in a horizontal position to move the tool carrier into the desired position. This fixed tension, which development to bring. Finally, the known Vorrich- 4 ° provided for each of the four tools 6 ', T, 8', 9 'device is not suitable for a precise adjustment of the is, has a screw 10, the axis of which to the tool with a very small radial play is parallel to the axis of the shaft 3, and cause its thread. . is engaged with the clamping piece 12, so that their

The invention is based on the object of creating a rotation of the clamping pieces 11 and 12 simultaneously with a manually switchable turret head for lathes 45 the tool inserted into the bore in Berühnen, which brings in the structure and in the tion and its effective clamping geHandhandung significantly simplifies is and also ensures. The axial play of the shaft 3 in the holder 1 an adjustment with a very small radial play is set by the nut 14, which allows one on the shaft of the tool carrier. The solution of the fine thread provided for the shaft 3 in engagement with this task is carried out according to the invention by a feature combination that stands up against the back of the holder 1, after which one is supported with the turret. The handle 15, which is firmly connected to the rear end of the shaft 3 and placed in a fixed axial position, is used to rotate the turret-mounted handle and a locking head with its tools,
The locking of the turret in one of the

verkopfes about an axis of the turret 55 four positions in which one of the tools in Arlagernden Holder is pivoted and brought optional work position in a horizontal plane wise in one of the circumference of the turret head is done by a locking lever provided groove engages, wherein the locking 21, which is firmly connected to the holder 1 on a control lever is pivotable in the area of the handle he axis 22 and in a vertical stretch and when the handle is rotated, the incision 20 located in the longitudinal plane of the holder 1 is actuated is cash. is movable. The front end of the locking lever

The turret head lever 21 designed according to the invention can be inserted into one of the four grooves 16, 17, 18 and 19 required, in contrast to the known design, we (Fig. 4) intervene, which in the turret head out a tension spring nor a claw coupling, where are formed, and their planes of symmetry through the is significantly simplified by the structure. There- 65 axes of the holes go so that they too by that the firmly connected to the turret head are offset from each other by 90 °. The front ab handle is held in a fixed axial position, section 23 of the locking lever 21 has a Furthermore, the radial play of the holder is very small, which corresponds exactly to that of the grooves, so that
