SU1256904A1 - Arrangement for mounting sealing rings into internal grooves of articles - Google Patents

Description

The invention relates to mechanical engineering and can be used in the assembly of elements of hydraulic and pneumatic equipment.

The aim of the invention is to increase reliability by reliably locating the ring in the eccentric socket, orienting it with the aid of the force element and the protrusion on the rod and inserting it into the groove of the base part with the help of a radius protrusion and a guide with a bevel.

FIG. 1 shows the device, a general view; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. one; in fig. 4 shows a section B-B in FIG. one; in fig. 5 is a section of YYD in FIG. one; in fig. 6 - the position of the device at the time of the capture ring stop; in fig. 7 - the position of the device at the end of the stroke of the rod with a fixed device; in fig. 8 - the final position of the device.

The device for installing sealing rings in the internal grooves of the products contains a housing 2 installed on the base 1 with a sleeve 3 located in it with a power element 4 having a tapered bore 5 and the socket 6 eccentric to it. The sleeve 3 is kept from rotation with respect to the housing 2 by a screw 7. Inside the sleeve 3 there is a piston 8 with a radial protrusion 9 at the end and a groove for the pin 10, limiting the stroke of the piston 8. A piston rod 12 is fitted in the piston 8 rigidly connected with the pusher 11 of the driving cylinder (not shown) hard stop 13, which is made in the form of a plate with a bevelled working surface.

The sequence of movement of the parts of the device is provided by the springs 14 and 15. Coaxially with the sleeve 3 on the base 1 set

Flax rotary drum 16, driven by a drive (not shown). A base mandrel 17 is fixed to the baraba 16, at the end of which a guide 18 with a bevel is mounted. The base part 19 is mounted on the mandrel. A sealing ring 20 is fed to the socket 6.

The device works as follows.

The sealing ring 20 along the vibrating hopper tray (not shown) is fed to the socket 6 of the power element 4. The base part 19 is put on by a loading device (not shown) on the mandrel 17 of the drum 16. The drive (not shown) rotates the drum 16 and inserts the part 19 into the assembly area. A driving cylinder (not shown) moves the pusher I, which transmits the movement of the piston 8 and through the spring 15 to the sleeve 3. The sleeve 3 moves up to the stop of the power element 4 in part 19 and stops, and the piston 8 continues to move. The rod 12 then passes through the ring 20. Upon further movement of the piston 8, the ring 20 in the conical bore 5 is pulled out along the rod 12 and caught by the stop 13 (see Fig. 7). The stop 13 reaches the part 19 and stops, while the spring 15 begins to compress. The upper edge of the working surface of the stop 13 is set against the edge of the groove of the part 19. The piston 8, while continuing to move, acts on the lower edge of the ring 20, and the upper edge of the ring 18 moves into the groove of the part 19. The piston 8 selects the stroke defined by the length of the groove and pin 10, and the lower part of the ring 20 is flattened in the groove. In this case, the end face of the piston 8 stops opposite the groove edge of the part 19, and its radius protrusion 9 presses the ring 20 into the groove (see Fig. 8).
