Abstract
A hollow component is adjusted in shape, for example to correct circularity, by means of a shape adjusting tool. The tool comprises a base structure on which adjuster elements are guided. An adjustment ring has a ramp surface corresponding to each adjuster element so that rotation of the adjustment ring causes radial displacement of the adjuster elements 6. The adjuster elements are displaced in unison, and engage the internal surface of the component to be adjusted so as to deform the component to the desired shape. The segments are interconnected by rigid links and a single flexible link, and are supported on bearing rollers mounted on the base structure.
Claims14
A shape adjusting tool for adjusting the shape of a hollow component, the tool comprising:
- a base structure carrying a plurality of adjuster elements which are distributed circumferentially about an axis of the tool;
- and
- an adjustment ring which is mounted on the base structure for rotation about the axis, the adjustment ring being resilient in the circumferential direction,
- wherein a respective ramp arrangement is provided on the adjustment ring corresponding to each adjuster element whereby rotation of the adjustment ring about the axis causes radial displacement of each adjuster element.
