The object of the innovation is to provide a device for pivoting and inserting a multi-tool clamp to create a working situation that is simpler, more reliable and also cheaper and that is not complicated Control mechanism requires.

This object is achieved according to the invention in that the The device has a piston which is designed as a hollow cylinder and can be linearly displaced longitudinally in a cylinder is mounted and a rotatably mounted tooth coupling with a helical groove is arranged centrally in the piston is, in which groove engages a fixed but rotatably connected to the piston roller and the one containing the groove Tooth coupling is arranged displaceably on a centrally extending shaft within the limits of a lock and with their end face facing away from the toothing in an end position of the piston at a: free end of the shaft arranged cutter rests, and in the other end position comes into engagement with the counter-toothing, which is fixed with eier axially displaceable and rotatably mounted shaft is connected.

The embodiment of the device according to the invention is shown schematically in the drawing in a partial longitudinal section shown.

The device for twisting and inserting sewing tool clamps consists of a cylinder 1, which at one end with a cover 2 with holes 3, 4 for alternating supply or discharge of a hydraulic or pneumatic pressure medium is provided, which is provided by a not shown Manifold is controlled. The second end of the cylinder 1 is provided with a cover 5 with a hole for the shaft 6 completed. On the outer side of the cover 5 are · ί Claws 7 are provided, in which the claws 8 of a ring 9 engage, which is firmly connected to the "shaft 6, on which a tool holder 26 is arranged. Moves in the cylinder 1." straight a piston 10, which is designed as a hollow cylinder and secured against rotation by a pin 11 is, the guide surfaces 12 against the flanks of the Ktit Support 13 in this piston 10.

Tool holders are attached to the widened end flange of the shaft 6 with the help of clamping pieces 26 and screws 27 28 excited.

The modernization device works as follows:

When supplying hydraulic pressure medium through the bore 3 to the right side of the piston 10 when the bore 4 with your drain is connected to the piston 10 and with it by means of the ball 18 under pressure and the notch 19 the toothed coupling 17 is also pushed to the left.

As a result, the claws 8 of the Hinges 9, which are fixed is connected to the shaft 6, from the claws 7 of the cover 5 disengaged. After the hanging of the longitudinal ball bearing 22 has been placed on the remaining end wall of the ceiling 5, the piston presses further movement of the ball 18 against the peder 20 out of the notch 19 and the hollow firmly connected to the piston 10 of the pin 14 moves in a straight line with the piston and twisted under the influence of the helical

The supply of hydraulic pressure medium to the bore A- is effected by means of the distributor and the bore 3 is opened to the The piston 10 comes back from the left end position to the right at the same time as the tooth coupling 17 connected to it via the ball 18 under pressure from the spring 20. The toothed coupling 17 is disengaged from the mating teeth 23 and presses on the screwed and secured cutter 21 on the shaft 6. The shaft 6 brings the claws 8 of the ring 9 into engagement with the claws 7 of the lick 5 through its axial movement to the right. Immediately after the claws 8 of the ring 9 engage in the claws 7 of the cover 5, the piston 10 lifts the ball 18 against the force of the spring 20, and the further linear movement causes the toothed coupling 17 to rotate back by means of the roller 15 and the helical groove 16 in the starting position. The ball 18 falls back into the notch 19.
