The plate 20 is placed vibrobots 24 associated tray-drive 25 with the groove 16 of the unit to supply pins. In the housing 1 also imeetzu the following.

The generator 27 with the satellite 28 approaches the device from the bottom to rotating the stop 29. This corrugated center 3 is in contact with the shaft 26 of the generator. Into the internal cavity of the stem 11, air is injected, the plunger-finder 12 is suitable to the shaft 26 and rotates with the shaft grooved center 3 plunger-finder sink down into the keyway of the shaft. In the cavity pnevmostartery 7, air is injected and the shaft 26 is fixed by the plunger 9 in the desired position. Thus the air in the cavity of the rod 11 is stopped and the plunger-finder 12 is given by the spring to the right in the rod 11, skipping the next key from the tray drive 25 in the groove 16 of the unit to supply pins. Next, air is supplied into the cylinder 14 by moving the plunger 15 with a radial plunger 17 and sandwiched between them is the key to the position opposite the key way of the shaft 26 is fully inserted in the screw 19. After that, air is injected into the right cavity pnevmostartery 10 and the rod 11 through the plunger-finder 12 supressive the key in the keyway of the shaft 26. When disconnecting the air supply system of the device, all nodes return to its original position.

This device allows to increase the reliability of the technological process of pressing, the Woodruff key is in automatic mode and build quality.

The DEVICE C is it rotational drive, the fixing unit shaft in the working position, vibrobots for dowels, site submission dowels in the area of pressing and pressing mechanism, wherein when the pressing feather keys in the shaft predominantly generators it is provided with a rack pivotally mounted on the bracket and tray-drive connecting vibrobots with the feed unit of keys, and a host of rotation of the hinge shaft mounted with the possibility of angular movement about an axis located perpendicular to the center node of rotation of the shaft, and axial movement relative to said axis, the feed unit of dowels in the area of the pressing placed perpendicular to the pressing mechanism, and the housing is mounted on the bracket.
