stretched and placed in the recess 9 of the housing 3. Then the actuator 5 lowers the sleeve 4, which with its conical protrusion 8 fixes the ring in the recess 9. Next, the assembly head rises and transfers the elastic ring to the assembly position. Here the assembly head is lowered again.

In this case, the pusher 6 abuts against the end surface of the base part and stops. and the elastic ring is placed opposite the groove in the base part. Then the sleeve 4 is raised and released ring, which is due to the elasticity is installed on the base part. 1 hp ff, 9

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

The aim of the invention is to increase reliability by reducing the deformation of elastic rings during their installation.

FIG. 1 shows the device, a general view; in fig. 2-9 - the main stages of installation of the elastic ring on the base parts.

A device for installing elastic rings on the base parts contains a loading device 1 with a conical finger 2 and an assembly head, in case 3 of which the sleeve 4 with the drive 5 and the spring-loaded plunger 6 are placed. On the finger 2 there are slots 7, and on the pusher 6 im slotted grooves. On the end surface of the sleeve 4 is made a conical protrusion 8; and in the hole of the housing 3 is made the recess 9 and the elastic ring 10.

The device works as follows.

The elastic ring 10 is fed to the tapered pin 2 of the loading device.

1 (Fig. 2). When the assembly head 25 moves downwards, the pusher 6 moves the ring 10 along the slots 7 of the finger 2. In this case, at the end of the stroke of the assembly head, the tension ring 10 is placed in the recess 9 of the housing 3 (FIG. 3). Then, with the actuator 5, the sleeve 4 moves 30 downwardly with the protrusion 8 and fixes the ring 10 in the recess 9 (FIG. 4). Next, the assembly head rises, removes it from the finger 2 and transfers it to the assembly portion, positioning it over the base part 11. When the assembly head is lowered, the pusher 6

rests against the base part 11 and stops, and the body 3 with the sleeve 4 continues to move downward, setting the elastic ring 10 against the groove in the base part 11 (Fig. 7). Then the sleeve 4 by the actuator 5 rises, the ring 10 is released and installed in the groove of the part 11 (Fig. 8). Next, the assembly head rises (Fig. 9) and returns to the loading position.

Claims of the invention • 1. A device for installing elastic rings on basic parts, comprising a loading device, a tapered pin 15 with slots and an assembly head in the form of a cylindrical body with an opening and an internal cavity in which a spring-loaded pusher with splined grooves is placed, and the pushers have the capability the interaction of their slotted grooves with conic finger slots, characterized in that, in order to increase reliability, the device is equipped with a sleeve in the axial direction, on the bottom end wherein the second surface of the protrusion is conical, and a conical finger is mounted on the loading device, in addition, on the inner end surface of the opening in the housing is formed a recess in which there is the possibility of placing the tapered projection of the sleeve, wherein the plunger is placed in the sleeve and spring-loaded relative thereto. 2. Device pop. 1.It differs from the fact that the sleeve is equipped with a drive mounted on the housing. 5 1646767 6 installation. The elastic ring is fed to the tapered pin 2. The assembly head is lowered and the pusher 6 moves the ring along the slots 7 of the finger 2. The elastic ring is then stretched and placed in the recess 9 of the housing 3. Then the actuator 5 lowers the sleeve 4, which with its conical protrusion 8 fixes the ring in recess 9. Next, the assembly head rises and transfers the elastic ring to the assembly position. Here the assembly head is lowered again. When this, the pusher 6 abuts against the end surface of the base part and stops, and the elastic ring is placed opposite the groove in the base part. Then the sleeve 4 is raised and released ring, which is due to the elasticity is installed on the base part. 1 hp ff, 9 ill. The invention relates to the process equipment and can be used in mechanical engineering). The aim of the invention is to increase reliability by reducing the deformation of elastic rings during their installation. FIG. 1 shows the device, a general view; in fig. 2-9 - the main stages of installation of the elastic ring on the base parts. The device for installing elastic rings on the base parts contains a loading device 1 with a tapered pin 2 and an assembly head, in case 3 of which there is a sleeve 4 with a drive 5 and a spring-loaded plunger 6. On the finger 2 there are slots 7, and on the push rod 6 there are spline slots corresponding to them . On the end surface of the sleeve 4 is made a conical protrusion 8, and in the hole of the housing 3 is made the groove 9 and the elastic ring 10. The device works as follows. The elastic ring 10 is fed to the tapered pin 2 of the loading device 1 (FIG. 2). When the assembly head moves downward, the pusher 6 moves the ring 10 along the slots 7 of the finger 2. At the end of the stroke of the assembly head, the tension ring 10 is placed in the recess 9 ′ of the body 3 (FIG. 3). Then, with the actuator 5, the sleeve 4 moves downwardly with the protrusion 8 and fixes the ring 10 in the recess 9 (FIG. 4). Next, the assembly head goes up, removes it from the finger 2 and transfers it onto the assembly portion, positioning it over the base part 11. When the assembly head is lowered, the pusher 6 abuts against the base part 11 and stops, and the body 3 with the sleeve 4 continues to move down, setting the elastic ring 10 opposite the groove in the base part 11 (FIG. 7). Then the sleeve 4 by the actuator 5 rises, the ring 10 is released and installed in the groove of the part 11 (Fig. 8). Next, the assembly head rises (Fig. 9) and returns to the loading position. Claim 1. Device for installing elastic rings on the base parts containing a loading device, a conical finger with slots and an assembly head in the form of a cylindrical body with an opening and an internal cavity in which a spring-loaded pusher with spline grooves is placed, and the pushers have the ability to interact with their spline grooves conical finger splines, characterized in that, in order to increase reliability, the device is equipped with an axially movable sleeve, on the lower end surface of which you The conical protrusion is full, and the conical finger is fixed on the loading device, moreover, a recess is made on the inner end surface of the opening in the housing, in which the conical protrusion of the sleeve is accommodated, the pusher being placed in the sleeve and spring-loaded relative to it. 2.
