Abstract

The invention relates to tooling of an automated assembly plant, and in particular to 2 devices for assembling sealing joints. The device comprises a power member and a housing with guiding elements. The power element is equipped with a flat guide element, and the housing is made up of a platform with a flat guide element and a removable socket with movable and fixed jaws, and the flat guide element of the force organ is located at a distance from the flat guide element of the platform , together with a mounted ring, form a cavity associated with a pressure source .2 ill.

Description

The invention relates to the technological equipment of automated assembly production and can find application in various branches of technology, in particular in machine, instrument and aircraft industry, ........

The purpose of the invention is to reduce energy consumption.

Deformation of the ring in the device according to the invention is carried out by fundamentally different means and methods.

Due to the presence of a deforming member made in the form of an airtight cavity formed by the lateral surface of the removable retainer, a flat guiding element of the housing and a flat clamp, the ring is deformed by air pressure without rotation at high frequency. By supplying compressed air through a hole made in the flat guide element of the housing, the ring in the sealed cavity is deformed along the flat guide element of the housing and the flat clamp to a diameter of the inner surface of the ring exceeding the diameter of the shaft being sealed.

Since the latch is made in the form of a clamping device with a fixed jaw and movable, after the ring is deformed, it becomes possible to fix it in a deformed state along the end surfaces. Removable latch allows the assembled shaft to be inserted into the hole for installing the sealing ring into the shaft groove.

In FIG. 1 shows the proposed device with a ring installed in it before deformation of the ring; in FIG. 2 - a removable latch with a ring clamped in it in a deformed state before installing the ring in the shaft groove.

The device includes a housing 1 and a removable latch 2 with a fixed jaw 3. The movable jaw 4 is made in the form of a sleeve with a flange, is installed in the latch 2 and is spring-loaded 5. The latch 2 for 00

covered with a cover 6 i., which has holes for fingers 7, pressed into the flange of the movable jaw 4. Under the lid 6 there is a gasket 8 that adjusts the upper position of the jaw 4, The flat clip 9 has an independent reciprocating drive, into the threaded hole of the housing 1 screwed fitting 10 for supplying compressed air.

The housing 1 and the flat clip 9 have flat guide elements 11 and 12.

The operation of the device is as follows.

A latch 2 is mounted on the housing 1. A ring 13 is thrown into the latch 2. The flat clip 9 is lowered into the latch 2, pressing the ring 13 with its flat guide element 12 against the flat guide element 11 of the housing 1 (Fig. 1). Compressed air is supplied into the sealed cavity 14 through the nozzle 10. After the ring 13 is deformed, the protractor-force organ 15 acts on the movable jaw 4 through the fingers 7, lowering it and clamping the ring 13 in a deformed state. The compressed air source is turned off, the flat clamp 9 is lifted, the transport and power member 15 removes the latch 21 from the housing 1 and conveys to the assembly position. The deformed ring 13 is aligned with the groove 16 of the assembled shaft 17 (Fig. 2), after which the movable jaw 4 is freed from the action of conveyor 0

force-body member 15 and ring 13, having restored its shape, self-installs in the groove 16 of the shaft 17.

The device provides for the assembly of sealing joints at much lower energy costs by using the energy of compressed air only to stretch the ring. Such devices can be implemented both on robotic complexes and as a hand tool,
