Abstract

Usage: mechanical engineering for the mechanization of the assembly of sealing compounds. SUMMARY OF THE INVENTION: The device comprises a cylindrical mandrel with two restrictive stops and a deforming finger sequentially connected with each other and two pneumatic drives for its movement along two coordinates in the diametrical plane of the mandrel. A pneumatic actuator associated with a deforming finger is placed inside the mandrel and is mounted for swinging in the center plane from the second pneumatic actuator. The deforming finger has the ability to interact with the cam, made in the mandrel. 6 Il.

The invention relates to process equipment and can be used in mechanical engineering to mechanize the assembly of sealing joints.

FIG. 1 given the device, a general view; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. 2; in fig. 4. 6 - the main stages of the device operation: in FIG. 5 - cross-section of the device in the plane of the elastic ring .;

The device includes a housing 1, with a replaceable cylindrical mandrel 2 fixed on it, inside of which on the projections 3 of the housing is mounted with the possibility of swinging on the axis 4 the housing of the power cylinder 5 of the pneumatic actuator connected by means of the rod 6 with the deforming pin 7. The spring 8 serves to return the rod 9 to the starting position.

The deforming finger is placed in a diametral groove made in the mandrel 2, the sides 9 of which (Fig. 2) serve

To prevent the deforming pin 7 from rotating around the axis of the rod 6. Supporting rollers 10 are mounted on the deforming finger 7. Contacting the device with cam inclined surfaces 11 made in the mandrel 2 when operating the device. Restrictive stops made in the form of rollers are placed on the lower end surface of the mandrel. 12 (FIG. 3) mounted on the pivot arms 13, swinging in the end plane of the mandrel 2 on the axes 14. The levers 13 are spring-loaded in the direction from the center of the mandrel 2 by the springs 15.

The case of the power cylinder 5 is connected by an earring 16 to the rod 17 of the second pneumatic actuator, the power cylinder 18 of which is made in the case 1. The limiting washer 19 is fixed to the projections 20 of the mandrel 2, serves to support the elastic ring 21 being installed (Fig. 4) and to limit its deformations in the vertical plane. The adjusting stop 22 is installed on СЬ

2 with movement along the axis of the mandrel and fixation.

Before the operation of the device, the stop 22 is set to a position corresponding to the depth of the groove 23 in the part 24 installed in the assembly position

The device works as follows.

The device mandrel 2 is brought to the loading position either manually or by means of a manipulator and takes up a position relative to the gate with an elastic ring 24 installed in it (see Fig. 4). In this case, the deforming finger 7 is in the lower left position, and the rollers 10 are in contact with the surfaces 11. Then the deforming finger 7 moves in the radial direction to the right, while the rollers 10 move along the cambeat face 11, providing a straight line of movement end of the deforming ring. The elastic ring 21 is deformed and takes the shape shown in fig. 5. The limit stops 12 thereby rotate on the levers 13, approaching the center of the mandrel 2.

Next, the device rises and transfers the deformed elastic ring 21 to the assembly position where the hole of the part 24 is lowered until the stop 22 contacts the surface of the part 24. In this case, the plane of the elastic ring 21 is aligned with the groove 23. Then the deforming finger 7 rises, a or- retaining stops 12, moving under

the elasticity of the springs 15 from the center of the mandrel 2 partially stretches the elastic ring 21. This allows the deforming pin 7 to be inserted inside the contour of the deformed elastic ring without using an additional separating element,

After that, the deforming pin 7 is lowered and the elastic ring 21 completely extends the reverse run in the radial direction, placing it in the groove 23 (Fig. 6). Next, the deforming pin 7 is retracted to the right, the device is withdrawn from the hole of the base part and returns to the loading position.
