    FIG. 1 shows a machine, a general view; fig 2 is the same radial section; in fig. 3 is a diagram of the movement of the part and the tool.
    The machine contains a stationary bed 1 with a rotating caroupe 2 with a four cropshins 3-6, which can move along its axis of rotation. On the lower part of each bracket, a part holder 7 is installed. Four brackets are served by four working posts, namely, the post of supply 8 of the processed parts P, the first post of processing 9, the second post of final processing 10 and the post of removal of the processed parts 11.
    Right-handed 5e motion of the rotary rotation and up-and-down duplication of the carousel 2, bringing into rotation
    Details of the tool are shown in phi1. 2
    The bed 1, made in the form of a table 12, is mounted on adjustable supports 13. The axis of rotation of the carousel 2 is a floor 14, which can rotate and move vertically in the bearing support 15. The rack 14 has a flange 16 at its upper end for mounting brackets 3-6 screws 17, and on the bottom a Maltese cross 18, rigidly connected to it, is installed, which is rotated by means of a finger 19, mounted eccentrically on a rotating drum 20, which is a cam with a groove 21, made on a peripheral edge hnosti 22..
    The drum 20 is rigidly coupled to a shaft 23 rotating in a bearing 24. A disk 25 also rigidly sits on a shaft 23.
    The shaft 23 is provided with a driven gear 26, which is engaged with the drive gear 27 mounted on the output shaft 28 of the engine 29.
    The rack 14 has at the base of the support flange 30 with a friction lining 31, interacting with the lower support block 32 having two fingers opposite each other
    33, connected with lever
    34 rotatably mounted about an axis 35 located on the uprights 36.
    The second end of the lever 34 is connected by a fork through the fingers 37 to a counterweight 38 mounted on the rod 39, with the possibility of free movement.
    Between the axis of rotation 35 and the axis of the fingers 33, the lever 34 has a crossbar 40 in the form of an axis 41 on which a roller 42 mounted in the groove 21 of the drum 20 is mounted.
    In the hollow frame 14, through an axial hole corresponding to the hole 43 in block 32, is mounted on centering bearings 44 and 45 a shaft 46 with an upper flange 47 supported on the bearing 45. In order to drive the holders of the parts 7, in its lower part it is equipped with a drive a pulley 48 connected by a belt 49 with a driving pulley 5Q mounted on the output shaft of the electric motor 51.
    In the upper part, the 46 fell with a pulley 52, connected by a belt drive 53 with pulleys 54, fastened first on axles 55, set to rotatably on bearing 56 on brackets 3-6.
    The axis 55 is connected by a cardan joint 57 to a splined shaft 58, a slid shzy in the slot 59 of the holder 7, which it causes to rotate. The shaft 58 has a protrusion 60 entering the cylindrical cavity 61 of the holder 7, and the pusher 62 serving as a pusher of parts. Spring 63 provides
    almost constant reference pressure of parts P on the grinding head M.
    The holder 7 terminates at an RRPD: Coy 64 provided with a stop recess,
    in which is installed elastic
    ring 65, in the form corresponding to the details. The ring 65 holds the parts P by elastic concentric compression. The holder 7 is lowered onto
    the part is at the supply point, and it is fixed in the ring 65 (Fig. 2) by the force of the spring 63 and is simultaneously pressed against the support 66.
    Part holder 7 has over
    the mandrel 64 is a flange 67 forming a recess 68 with the mandrel used to push out the machined parts. The cylindrical housing parts holder 7 is installed with the ability
    rotation is eccentric in sleeve 69, which is also mounted eccentrically in sleeve 70, rotating in Bearings 71 and 72, with adjusting the angular position relative to
    sleeve 70.
    The sleeve 70 in its upper part has a gear 73 fixed on it, which engages through the gear 74 with the central gear 75, which is fixed to the shaft 46. The angular relative position of the sleeves 69, 70 is adjusted by means of flanges on them.
    equipped with scales and clips, fixing them in the desired position (not shown). The parts are given rotation through pulleys 52 and 54 around the axis of the holder 7, on which planetary motion is superimposed relative to the axis of sleeve 70, dependent on adjusting the relative angular position of bushings 69, 70. This movement is communicated through gears 75, 74 and 73.
    The rotational movement Rp of the part P around its axis and the auxiliary movement Rg around the axis of the sleeve 70 decouple in the direction opposite to the direction of movement R of the grinding head M. The machining time is divided into two parts for adjusting the working conditions of the machine. The auxiliary movement allows better flatness of the machined surface, reducing defects, which can be called the possible non-perpendicularity of the axis of the grinding head relative to the ground plane.
    The considered parts P are half of the ferrite magnetic armor core, in which the central projection plane N is machined to create a predetermined gap in the magnetic armor as a result of the connection of the two halves. The gap depends on the required value of inductance and must, in general, be performed with an accuracy of the order of microns
    The auxiliary motion axis and the grinding wheel axis M are offset relative to each other, as shown in FIG. 3, which makes it possible to improve the resulting flatness of processing in the presence of defects in the surface of the grinding wheel (for example, a convex surface).
    The grinding wheel M is fixed at the end of the tool spindle 76, the body 77 of which is mounted in the mounting stand 78 fixedly attached to the table 12. In the lower part, the fork has a pulley 79, which is connected with a driving pulley 81 attached to the output shaft of the electric motor through a belt transmission 80 82 The support 78 is provided with a support table 83, the reference plane of which can be adjusted in height with a special precise mechanism designed to adjust the displacement of the plane of the grinding head relative to the reference plane. and depending on trebogany details.
    At the station for supplying the workpieces 8 at a height close to the height of the plane of the tsifrirovat head, there is a base plane 84, above which is mounted a vertical trough 85 with parts P laid
    headquarters. The lower part of the shell is open and 1 tripod above rLnocKocTf.u) 84 iia height, ncMHi io greater than the thickness of part P.
    That is, the caterer 86, smaller in thickness, P, CKOJ b3HT and the plane 84 under the chute, so that using the reciprocating movement to bring the children one by one from the chute to the feed position, in which the part P can be gripped by the holder of the part 7 at stopping rotation and lowering the carousel. Backward Motion Pusher
    86 is received from the disk 25 on the shaft 23, the pa of which is located eccentrically a roller 87, which interacts with the stop 88, fixed at the end of the rod 89, movable in the guide 90.
    The rod 89 is connected to its second
    through the pin 91 with the rear pusher 86. At the same time, the pin 91 is connected through the spring 92 and the bolt 93 with the table 12, ensuring a constant
    contact roller 87 and stop 88.
    A removal post 11 of machined parts P contains a supporting square 94 s, 1 with a fixed finger 95 (FIG. 1), positioned so that
    enter the ring groove 68 of the part holder. While the carousel is being lowered, the finger 95 holds the holder 7, while the pusher 62 of the shaft 58, lowering together with the carousel, pushes the machined piece P out of the holder 7,
    The machine works in the following way. Maltese cross drive causes intermittent rotation
    carousel 2 by a quarter turn for one revolution of drum 20 with finger 19 (see FIG. 3), during which the carousel is held in the upper position by block 32 due to interaction of roller 42 with groove 21 of drum 20. Carousel 2 is lowered and remains some time lower position during which the machining of parts P takes place, then rises to
    top position before a discontinuous quarter-turn rotation begins. When the carousel is lowered, the part is captured at the feeding platform 8, as described above. The grip of the new part P by the pusher 86 is made during processing, and its supply ends during the next turn of the carousel.

    The friction connection of the MSS, the carousello and the block 32 ensures the elimination of the 1-: action — inertia forces that can disturb the praggil angular position of the carousel brackets. The connection is secured, but it may be reinforced with a spring or with the insert of the brake i with the brakes.
