performed on the fixed part 97 of the coupling 91.

The latter is mounted on the shaft 71 with the possibility of contact with the rollers 98 (Fig. 9) mounted on the fork 44 of the switching mechanism of the executive bodies, and the rollers 995 fixed on the fork 45 are mounted with the possibility of contact with the shifting ring of the friction clutch 60 ..

On housing 1 (FIG. 1), the fastener 100 of the rotary faceplate 17, which is under the action of the spring 101 and connected via the lever 102 to the rod of the pneumatic cylinder 103, is hinged.

On the housing 1 is also fixed drive rammer wedges, including a pneumatic cylinder 104, the rod of which is fixed strap 105 with two lugs 106 and with one or three gates 107, according to the number

one

The sheared gate valves scatter the wedges and are retained from the angular displacement of the guide 108.

On the base of the semiautomatic device, besides the housing 1, the stator clamping mechanism 109 is mounted on mandrels 18 (positions II and III), equipped with pressure plates 110 and 111, and the stator removal mechanism 112 (position IV) is equipped with a gripper 113. Both these mechanisms 109 and 112 are kinematically connected to each other and may have a common drive from the pneumatic cylinder 114.

Semiautomatic works as follows.

When: air is supplied to the pneumatic system and the electric motor 55 is turned on, the movement from it through the shaft 56 and the worm gear 57 is transmitted to the camshaft 58, and all the mechanisms of the semi-automatic machine return to their original position: the lock 100 is inserted into the faceplate 17, the stators 19 to the position x II and III for 1sat by pressing presses 110 and 111 (fig. 1); at position IV, the stator is removed from the mandrel 18 by gripping 113z the coupling 36 in the stator turning mechanism circuit is on, i.e. the right coupling sleeve 40 is in the groove 39 of its left side, while the mandrel 18 at position II is fixed, i.e. the latch 41 is removed from the socket 43, the friction clutch 60 is turned off, and the brake clutch 91 is turned on, rigidly connected forks 44, and 45 of the mechanism

The actuator switches are in the leftmost position, and the 47 L-shaped roller is in the rightmost position, i.e. in the neckline pinion 62 strap. 105 drive rammer wedges on pos. III is in the leftmost position.

The friction clutch 59, sitting on the shaft 58, is adjusted for a small torque, therefore, due to its pickup, the shaft 67 through the gears 61, 63, 64 and 66 lash until the finger of the crank 68 approaches the next groove of the Maltese cross 69, sitting on the same shaft with the face plate 17 fixed at that moment, and then the coupling 59 will start to slip. After turning on the semi-automatic mode, the machine is ready for operation.

The mandrel 18, located at position 1, is manually put on the stator 19 with a winding and pressing a button on the console gives the command to actuate the pneumatic cylinders 114 and 103 and to bleed air from the cavity of the pneumatic cylinder 34 of the coupling 36. At the same time, the pneumatic cylinder rod 114 moves to the left removes

the pressure cups 110 and 111 of the clamp mechanism 109 from the mandrels 18 at positions II and III, and the gripper 113 of the mechanism 112 moves towards the mandrel at position IV. Pneumatic cylinder rod

103 through the lever 10., overcoming the force of the spring 101, leads the retainer 100 out of the slot of the faceplate 17, and when air is released from the pneumatic cylinder 34, the coupling 36 is turned off, i.e. the spike 40 comes out of contact with the groove 39, while under the action of the spring 42 the retainer 41 enters the socket 43, fixing the mandrel 18 in the angular position. At this time, the crank 68 enters the groove of the Maltese cross 68 and turns

shakes clockwise faceplate 17 by 90,

At the end of the rotation of the faceplate from the pneumatic cylinder 103, the air is rationalized, while the latch 100 under the action of the spring 101 re-fixes the faceplate and giving the command to trigger the hinges of cylinders 114 and 34, causing the cups 110 and 111 to move towards the mandrels. 18, they clamp the stators 19 to positions II and III, and the grip 113, moving from the bay, seizes the stator to position IV and removes it from the transfer, the coupling 36 again

the shaft 5 is connected to the roller 21, and the latch 41 comes out of the socket 43. After that, a command is given to supply air to the pneumatic cylinder 53 of the switching mechanism of the executive bodies, and the rod 52 moves the H-bar, the roller 47 leaves the cutout 94 of the pinion gear 62, and turning around the axes 50 and 51 parallel levers 48 and 49 towards the L-shaped bar, moves the rigidly attached forks 44 and 45. Having overcome the force of the spring 92, the protrusions 95 and 96 of the friction clutch were disengaged 91, disassembling while the driven shaft 71 and turn on The camshaft friction clutch 60 60. Once this happens, the movement from the pinion gear 62 is transmitted to gear 70, and then through bevel gears 72 and 73, crank 74, axis 75, Maltese cross 76, shaft 77, gears 78 and 79 - to the roller 6 of the material feed mechanism, which, rotating, moves the material 7, pressed against it by the roller 9, under the action of the spring 10.

The end of the feed of the material coincides with the beginning of its cutting. The movement from gear 70 through bevel gears 72 and 80, crank 81, axle 75, maltese cross 82, shaft 83. gears 84 and 85, shaft 86, gears 87 and 88 is transmitted to the shaft 3 of the parting mechanism and the guide mechanism, from which, through the crank 11 and the stud 12, the movement is then transmitted to the lever 13, which serves to direct the material of the wedge and carries the knife 15 at its end. The lever 13, turning around the axis 14, receives a swinging motion, during which the knife 15 interacts with the stationary knife 16, abbreviated at the same time, a wedge 115 engraved in the groove. After the wedge is cut, without waiting for the end of the movement of the lever 1.3, the stator turning mechanism is activated in which the crank 5 is transmitted through the crank 89 and the Maltese cross 90 to the shaft 36 at that moment coupled with the roller 21 and, therefore, there is a rotation of the mandrel 18 with the stator 19 at an angle corresponding to the next jammed groove. The end of the rotation of the stator coincides with the beginning of the filing

material into the next groove. All the above transitions to position II are repeated until all wedges are fully baited and cut off.

Simultaneously with the process of filing, cutting and turning the stator at position II, at position III, all the wedges are fed into the stator slots. Pneumatic cylinder 104, the rod of which moves the bar 105 in the direction of the mandrel. With its protrusions 106, the bar 105 presses on the ends of the rollers 29 and 30, while the gates 107 align with the gates 26 lining up the wedges to form a complete vicious circle of the gates, the number of which corresponds to the number of stator loops wedged. Upon further movement of the strip 105, the sleeve 27, overcoming the force of the spring 33, slides along the cylindrical part of the housing 31 of the roller support 21, the hooks 26 and 107 simultaneously send all the wedges into. the stator grooves to the required value, after which the pneumatic cylinder 104 is switched, the bar 105 with the slider moves back, the wedge spraying device under the action of the spring 33 takes the initial position.

While work is being carried out at positions II and III, the next stator is installed on the mandrel of position I, and, not waiting for the end of the cycle, press the Start button of the cycle, the command of which is memorized.

Once on position II all the wedges in the stator are tapped and cut off, a command is issued to bleed air from the pneumatic cylinder 53, and this command is given in advance for the last three periodic rotations of the stator. In this case, the 47-g-g-shaped strip under the action of the spring 92 is pressed against the end surface of the pinion gear 62 and rolls along it until it enters the notch 94. At the same time, the L-shaped strip and rigidly fastened forks 44 and 45 move in opposite directions, the clutch 60 is disconnected, the brake clutch 91 is turned on, and the protrusion 95 comes to the protrusion 96 until it contacts, locking the driven shaft 71. At this cycle is completed, all mechanisms are in the initial position.
