<p>The system consists of a pair of reference surfaces (10, 16) on the first (3) of two components, lying parallel to one another and to a predetermined direction. The first component has another pair of reference surfaces (25, 26) which are parallel to one another and to the predetermined direction, but not parallel to the first pair, and it also has a stop (26) lying perpendicular to the predetermined direction. A second component (2) has a first pair of thrust surfaces (31a, 31b) which are parallel to one another and to the predetermined direction, designed to make contact with the corresponding reference surfaces of the first component, sliding along them in the predetermine direction until the components are aligned. It also has a stop (34) to engage with the stop surface (236) on the first component.</p> |
