SU1484548A1 - Apparatus for setting seal rings into inner grooves of parts - Google Patents

Abstract

The invention relates to mechanical engineering and allows to expand the technological capabilities and increase reliability due to the possibility of pre-deformation of the ring to be installed and its distribution into the base part groove evenly along the entire perimeter. After installing the coupling on the mandrel, the rod receives movement from the actuator. Initially, the magazine and the pusher move together with the rod. When the drive reaches the clutch, the magazine stops, and the plunger, while continuing to move, deforms the rings with cone-shaped protrusions and drops the lower of the rings into the coupling groove. Then the pusher stops, and the rod spreads the cams with its pressure cone. Due to this, the ring is poured into the coupling groove. 4 il.

Description

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

The purpose of the invention is the expansion of technological capabilities and increased reliability due to the possibility of pre-deformation of the installed ring and the filling of the ring into the groove of the base part evenly around its perimeter.

Figure 1 shows the device, a general view; figure 2 - section aa in figure 1; fig.Z - the same, after resetting the ring into the groove of the base part; figure 4 - section bb in fig.Z.

The device contains a frame 1, a base fixture 2 with a mandrel 3 for placing a base part on it - a coupling 4, a magazine 5 for accommodating sealing rings 6 with a pusher 7 and a rod 8 spring-loaded relative to it, as well as a power drive 9. The mandrel 3 is provided with evenly around the circumference by the cams 10 mounted on the elastic plates N. On the outer surface of the store 5, the juice 12 is centered, and the opening 13 in the store 5 is made conical and provided with extra conical projections 14. The lower end w eye 8 is designed as a pressure cone 15.

The device works as follows.

After installing the clutch 4 ku 3, the drive 9 is turned on. Together with the pusher 7 and the magazine 5, they move down to the stop centering 12 on the mufg 4. At the same time, the magazine 5 stops and the ram is pushed.

The body 7, continuing the downward movement, pre-deforms the rings 6 with the help of the projections 14 and cuts the lower of the rings 6 into the groove of the coupling 4. The movement of the pusher 7 stops, and the rod 8 continues to move and spreads the cam 10 with its pressure cone 15 into the groove of the coupling 4. After the drive 9 is disconnected, the magazine 5, the pusher 7 and the rod 8 are returned to their original position and the assembled assembly is removed from the mandrel 3.
