Description

one

The invention relates to the field of assembly operations, for example for mounting cylinder liners.

A device for mounting cylinder liners is known, comprising a housing mounted on a cylinder of a drive cylinder with rotatable spring-loaded grippers mounted on it, and also a sleeve 1 installed outside the housing.

A disadvantage of the known device is the impossibility of automating the installation of sleeves due to the need to install removable grips on each pressed sleeve.

To automate the mounting sleeves in the proposed device, the housing is made in the form of a glass with an annular groove for the ends of the grippers and longitudinal grooves, and the sleeve is made with an inner lower and outer upper end flanges and is equipped with fixing screws that enter the longitudinal grooves of the housing.

FIG. 1 shows the proposed device, a general view; in fig. 2 — node I in FIG. one.

The device includes a housing made in the form of glass 1, rigidly fixed with bolts 2 on the rod 3 of the power cylinder 4 mounted on the cross bar 5. The glass has an annular groove 6 with a conical and surface

for inserting the ends of the radius arms of the grippers 7. The sleeve 8 is loosely mounted on the sleeve 1, which is fixed from the transverse and restricted from longitudinal displacement relative to the glass fixed by means of screws 9 inserted into the grooves 10 made in the upper part of the sleeve 1. On the sleeve 8 there is a lower inner shoulder 11 and an upper outer shoulder 12 for transmitting movement.

from the cup 1 to the press-fit sleeve 13. The hinge grips 7 are fixed to the axles 14 in the sleeve 8 and spring loaded 15. The sleeve 13 is installed in the case of the cylinder block 16 together with the sealing rings 17.

The proposed device works as follows. The circulating sleeve 13 is put on the sleeve 8 and is held on it by the grippers 7. When the stem 3 of the power cylinder 4 is lowered, the housing with sleeve 8 and sleeve 13 is lowered until the rings 13 of the cylinder block 16 are sonified.

The pressed-in sleeve 13 under the action of the friction force that occurs between the sealing rings 17 of the sleeve 13 and the cage-compatible opening of the cylinder block 16 stops, and the stem .3, the sleeve 1 and the sleeve 8 continue to move downwards.

The movement of the stem 3, the sleeve and the sleeve 8 will continue until the upper collar 12 of the sleeve 8 contacts the upper end of the pressed sleeve 13. The movement of the sleeve 8 stops and the glass 1 continues moving along with the stem 3, the conical groove 6 having a tapered surface contact with the shoulders of the grippers 7, inserted through the grooves in the sleeve 8 into the groove 6, and upon further movement of the glass down the conical surface of the groove 6, pressing the ends of the grippers 7 inserted inward around the axis 14, will release the sleeve 13 from the grips 7. Further Moving the cup I downward, it propels its lower end into the lower inner shoulder 11 of the sleeve 8. At this point, the claws 7 will be separated by the tapered surface of the glass 1 by an angle preventing them from contacting the cylinder block 16 during the end of the press-fit. Further movement of the rod 3 will be transmitted to the glass 1, which by its lower end transfers the force to the lower inner shoulder 11 of the sleeve 8, and it, in turn, with its upper outer shoulder 12 transfers the force to the upper end of the pressed sleeve 13. The final pressing of the sleeve 13 into the cylinder block occurs. sixteen.

After pressing the sleeve 13, the cup 1 and the sleeve 8 will be returned to their original position by the rod 3 of the power cylinder 4.
