The invention relates to mechanical engineering, in particular to assembly devices, and can be used in the automotive industry.

The purpose of the invention is to increase the productivity due to the unimpeded passage of the elastic ring with the tips of the spring-loaded arms rejected.

The drawing shows a device for installing an elastic ring, a longitudinal section.

The device for mounting the elastic ring comprises a housing 1 with a mandrel 2 for accommodating the clamping part 3 coaxially placed with a guide element in the form of a truncated cone 4, the sleeve 5 formed with a gap in the circumferential direction and spring-loaded elastic element 6 in the radial the direction of the petals-7 with the inner surface 8 for periodic interaction with the outer surface 9 of the truncated cone 4 and the end surface for the periodic interaction with the elastic ring 10.

On the device are placed the double-arm levers 11 and the corresponding stops 12, which are pivotally mounted in the housing 1 and are spring-loaded to it. One with one of the arms of the corresponding lever 11. On the outer surface 9 of the truncated cone 4 are made symmetrically with a gap between the petals 7 longitudinal

in the radial direction by the petals 7 with the inner surface 8 for periodic interaction with the outer surface 9 of the truncated cone. 4 When the sleeve 5 moves, with its end it picks up the elastic ring 10, puts it on the lead-in phase of the cone 4, grabs and moves the latter to the stop 16 With further movement of the sleeve 5, the ring 10 slides off the cone 4 and is put on the part 3. 1 Cp f-ly, 1 ill.

grooves 13 with which, as well as with the side surfaces of the petals 7, the free ends of the levers 11 are intended to interact. The mandrel 2 is made in the form of pads 14 placed in staggered order with respect to the petals 7 of the sleeve 5 for passing the latter between them. The number of levers is 11. equal or a multiple of three. The device has a mechanism 15 for feeding the elastic ring 10 and an emphasis 16 rigidly fixed in the housing 1.

The device for installing an elastic ring works as follows.

When the sleeve 5 moves toward the elastic ring 10, it with its end removes the last of the nests of the feed mechanism 15 and moves it towards the guide element. Continuing a forward movement, the elastic ring 10 is put on the lead-in chamfer of the cone 4, thereby catching the cone and moving it towards the clamping part 3. The cone 4 touches the part 3, lifts it towards the locking 16 and presses it. As the sleeve 5 continues its movement, and the cone 4 is stopped by the stop 16, the elastic ring 10 moves along the axis of the cone and. stretching it to the inner diameter. Upon contact of the ring 10 with the end of the lever 11, the latter begins to turn relative to the hinge. The levers 11 are positioned against the gap between

petals 7 sleeves 5. Narrow areas 14 easily bend around elastic ring 10. After passing ring 10, spring-loaded levers 11 return to their original position to stops 11, falling into the gaps between petals 7 of sleeve 5 and into grooves 13 of cone 4, Ring 10, advancing Subsequently, under the action of the sleeve 5, it jumps off the cone 4 and is put on the part 3. When the hyeses 5 returns to the initial position, the cone 4 also returns to its original position. The feed mechanism 15 inserts the new elastic ring 10 and the next part in the mandrel 2,

The cycle of operation is repeated. The use of the invention makes it possible, by automatically feeding the mounted elements with a continuously operating device, to increase the productivity of the work.
