Abstract
Device for the remote control of the center distance of two bores or two cylinders with parallel axes in a structure with high dimensional accuracy, comprising a base plate (24) having a part (24a) for the accurate positioning of the device, two centering pins (26, 27), engageable in a perfectly coaxial position on the bores or cylinders (22, 23), two unit assemblies (33, 32') each carrying one of the pins (26, 27), articulated for moving the pins (26, 27) in any direction at right angles to the axes of the bores or cylinders (22, 23) and a distance detector transmitting transducer (50) fixed on a support (45) fixed integrally to one of the pins (26) and joined to the other pin (27) with some play in the direction of the center distance. The rod (51) of the detector (50) is directed along the direction of the center distance and its end is in contact with the pin (27). The device applies, particularly, to the control of the upper internal parts of a pressurized water nuclear reactor.
