Abstract
A device, a modular construction system and a method for inserting an elastic ring into an inner groove of a workpiece opening provides that the device the ring is fixed by multiple retainers to specific retaining regions and between the retaining regions said ring acquires a wavy shape or crown shape in an axial direction.
Claims20
A device for inserting an elastic ring into an inner groove in a workpiece opening, said device having:
- at least two retainers that are circumferentially spaced apart from one another and can slide into the workpiece opening with regard to an axial insertion direction (B), each of said retainers having a radially outwards open recess for retaining regions on the ring,
- wherein the device is configured so that the ring that sits in the recesses can deform between its retaining regions to form a wavy shape, seen in a lateral view, in order to form trailing, curved regions,
- at least one slider for pushing the trailing, curved regions in the direction towards the inner groove, wherein the device is configured such that the slider can be moved into the workpiece opening in a trailing manner with respect to the recesses, and
- wherein a mouthpiece is provided with a guiding aperture for the ring to be pushed through in the direction towards the workpiece and for deforming the ring, wherein the retainers together with the inserted ring and the slider can be pushed axially through the guiding aperture.

A modular construction system having a device with
- at least two retainers that are circumferentially spaced apart from one another and can slide into a workpiece opening with regard to an axial insertion direction (B), each of said retainers having a radially outwards open recess for retaining regions on a ring,
- wherein the device is configured so that the ring that sits in the recesses can deform between its retaining regions to form a wavy shape, seen in a lateral view, in order to form trailing, curved regions,
- at least one slider for pushing the trailing, curved regions in the direction towards an inner groove, wherein the device is configured such that the slider can be moved into the workpiece opening in a trailing manner with respect to the recesses, and
- multiple mouthpieces, each mouthpiece having a guiding aperture for the ring to be pushed through in the direction towards the workpiece opening and for deforming the ring and each having an axial outlet end, wherein the retainers together with the inserted ring and the slider can be pushed axially through the guiding aperture, wherein
- the mouthpieces differ from one another by virtue of different diameters of the guiding apertures in the region of the axial outlet end, wherein the slider and the retainers can be coupled to each of the mouthpieces so that during the insertion procedure the retainers can make contact adjacent to their recesses with an inner face of a wall of the mouthpiece, said wall forming the guiding apertures.
