Abstract

The invention relates to mechanical engineering and makes it possible to increase the reliability of the assembly due to the possibility of left-serving the ring and eliminating its displacement during removal of the device. When compressed air is supplied to the elastic sheath 2, the elastic ring 7 is stretched and supplied by the actuator 4 to the base part 6. Next, the pressure in the sheath 2 is relieved and the actuator 4 returns the sheath 2 to its original position on the rod 1. At the same time, they move in radial directions. the stops prevent the ring 7 from moving relative to the base part 6. In another design of the device, the elastic chamber is made up of several annular chambers with a conical outer surface, into which the compressed air is successively supplied. In this case, the ring 7 slides off the chambers, shuffles along the stem I until it is installed on the base part 6. 2 Cp. f-ly, 4 ill. S (l

The invention relates to process equipment and can be used in mechanical engineering.

The aim of the invention is to increase the reliability due to the possibility of axially feeding the ring and eliminating its displacement during the retraction of the device.

In figure 1. depicts the proposed device in the first version, a General view; figure 2 and-3 - stages of installation of the ring; figure 4 - the proposed device in the second version, a General view.

The device (Fig. 1) contains a rod 1, an elastic sheath 2, connected through a sleeve with a pneumatic system (not shown) and with a drive 4, as well as stops 5 that are movable in radial directions (Fig. 3). Assembled parts: rigid base part 6 and retaining ring 7. In another design (Fig. 4, the elastic shell is made in the form of annular chambers 8-10, each of which is independently connected to the pneumatic system. The outer surface of the chambers 8-10 is made by a horse. .

The device works as follows:

An elastic ring 7 is installed on the shell 2, after which compressed air from the pneumatic system is fed into it. The extended ring 7 is moved by the actuator 4 to the right along the base part 6, after which the pressure in the sheath 2 is relieved and returned to its original position on the rod 1.

In this case, the stops 5 move from the actuator (not shown) to the center of the rod 1 and prevent the ring 7 from moving to the left.

In another design of the device (Fig. 4), the elastic ring 7 is first mounted on the first of the annular chambers 8, into which air is then compressed from the pneumatic system. In this case, the ring 7 is stretched and slides along the conical outer surface of the chamber 8 onto the chamber 9. Next, the pressure in the chamber 8 is relieved and the compressed air flows into the chamber 9, which causes the ring 7 to move to the chamber 10. The extended ring 7 is released from it on the base part 6.
