The invention relates to a device for adjusting the centring of a turbo-engine pivoting vane control ring, comprising a control ring (26) centred on a longitudinal axis (X-X) of the turbo-engine and provided with a plurality of tapped holes (36) running in a radial direction and a plurality of pad h
The invention relates to a device for adjusting the centring of a turbo-engine pivoting vane control ring, comprising a control ring (26) centred on a longitudinal axis (X-X) of the turbo-engine and provided with a plurality of tapped holes (36) running in a radial direction and a plurality of pad holders (32), each comprising a threaded rod (34) screwed into one of the ring's tapped holes (36), each pad holder (32) holding, at an inner end, a pad (30) intended to come into contact with a cylindrical shell (28), coaxial with the ring. The control ring (26) comprises, in addition, a plurality of slots (38) running in a tangential direction, each slot (38) communicating with one of the ring's tapped holes (36) The device comprises means (40, 42a, 42b) of pinching, in a longitudinal direction, each of the slots (38) in such a way as to lock the pad holders (32) in position.

The invention claimed is: 1. A device for adjusting the centring of a turbo-engine pivoting vane control ring, comprising; a control ring centred on a longitudinal axis of the turbo-engine and provided with a plurality of tapped holes running in a radial direction of the control ring and a plurality of pad holders, each of the plurality of pad holders comprising a threaded rod screwed into one of the tapped holes of the control ring, each pad holder holding, at an inner end, a pad intended to come into contact with a cylindrical shell coaxial with the control ring, wherein the control ring comprises, in addition, a plurality of slots running in a tangential direction and going through the control ring radially, each slot communicating with one of the tapped holes of the control ring and wherein the device comprises means of pinching, in a longitudinal direction, each of the slots in such a way as to lock the pad holders in position. 2. A device according to claim 1, wherein the control ring comprises, in addition, a plurality of holes running in a longitudinal direction of the control ring, each hole communicating with one of the slots of the control ring and wherein the device comprises a plurality of bolt-connection systems, each inserted in one of the holes in the control ring in such a way as to effect pinching, in the longitudinal direction of the control ring, of a corresponding one of the plurality of slots. 3. A device according to claim 1 wherein each slot runs, at a tangential end of the respective slot, into one of the tapped holes of the control ring. 4. A device according to claim 3, wherein each slot runs, at a tangential end opposite the tapped hole, into a smooth bore that extends through the control ring radially. 5. A turbo-engine, comprising; at least one device for adjusting the centring of a pivoting vane control ring according to any one of claims 1 to 4.
