Method for mounting side doors on motor-vehicle bodies, wherein the doors are connected to the body by means of a pair of hinges each providing a pivot for support and articulation of the door. Each hinge is constituted by a body (fixed) element connected to the body and a door (movable) element connected to the door, as well as by a pin for their mutual rotational articulation. The method comprises the steps of: - detecting - by means of optoelectronic systems - a plurality of dimensions measured along coordinates X, Y, Z, on the body and on the door units, with the aid of the proper references, for qualifying the geometric conditions of the coupling between the doors and the cooperating door receiving seats, - on the basis of the detected dimensions, determining the mounting positions of each pair of hinge elements to be secured to the body and to the doors, so as to obtain that the doors, in the closed condition thereof, are consistent with the respective door receiving portions on the body sides according to the assembly project drawing, - mounting the aforementioned hinge elements on the body in the thus determined positions, using tools that arrange the upper and lower body hinge elements obtaining the alignment of their axes and the correct conjugation of the pivots, - mounting the doors on the body by connecting the body hinge elements and the door hinge elements to each other by simply simultaneously inserting the articulation pins in the seats thereof, without requiring performing further operations for adjusting and recording the geometrical settings, neither on the pre-painting body completion line, nor on the final vehicle assembly line. |
