Description

1219307

refers to automatism but k

assembly equipment and can be used in mechanical engineering and instrument making.

The purpose of the invention is to increase the reliability of assembling split rings by eliminating the possibility of skewing and jamming of the installed rings in the hole of the inner mandrel.

FIG. 1 shows the proposed device, a general view ;, FIG. 2 shows section A-A in FIG. one; in fig. 3 is a view B in FIG. one.

The device comprises a frame, in the landing hole of which the power cylinder 2 is mounted and fixed. On the rod 3, which is also an internal mandrel, is the upper part A of the external mandrel, in which the conical bore 5 is made. The device also contains end cams 6. A compression spring 7 is installed between the power cylinder 2 and the upper part D of the outer mandrel. In the lower part 8 of the outer mandrel, cylindrical 9 and conic 10 bores are made on one side, and conic 1I on the other. On the side of the cylindrical bore 9, the end cams 12 are inserted. The directional speakers 13 connect the upper 4 and lower 8 parts of the outer mandrel, which are oriented so that the depressions on the opposite part are located against the cams 6 and 12. The springs 14 provide relative position of the parts in the vertical plane, adjustable by nuts 15. Forks 16 fixed on the base 1 limit the vertical movement of the parts 4 and 8 of the outer mandrel in the absence of the base part 18 through the nuts 17, while preventing their rotation around the vertical axis. At the same time, the gate 19 has the ability to pass between the cams 12. The core magazine 20 is fastened to the frame I, on which the circlips 21 are strung. The guide protrusion 22 ensures their desired circumferential position;

capture the assembled ring 2, which is to be installed in the groove 24 of the base part 18.

The device works as follows.

When moving to the left, the gate 19 with the ledge 23 cuts off the ring 21 from the magazine 20 and with further movement supplies it to the cylindrical bore 9 of the lower part 8 of the outer mandrel,

whereupon the gate returns to its original position. When supplying the compressed air into the upper cavity of the power cylinder 2, the inner mandrel 3 is lowered. Simultaneously under the action

the springs 7 and 14 lower the upper and lower portions of the outer mandrel. The lower part 8, reached the end of the base part 18, with its conical bore 11 centers and presses it to

base of the bed 1. Upon further movement of the upper part 4, the deformation of the springs 14 occurs, and the cams 6 enter into the depressions between the cams 12. In this case, the conical boring 5 centers the retaining ring 2 and, deforming it, pushes through the conical bore 10. The inner mandrel 3 at In its further movement, the locking ring 21 is sent to the groove 24 of the base part 18. When compressed air is fed into the cavity of the power cylinder 2, the mandrel returns to its original position.
