Abstract:
A method of making car bodywork, the method including a step of assembling body sides to an underbody, the underbody including a rigid engine compartment at one end and being placed in an assembly station in a precise position determined in an orthogonal frame of reference having directions X, Y, and Z, the method consisting in putting the body sides into position and holding them in position in the frame of reference of the station by means of two parallel tools each co-operating with a respective body side, and by means of at least one transverse tool extending transversely to said parallel tools, the three tools operating independently and being connected to one another and to the X, Y, Z frame of reference of the station by positioning to the two parallel tools in the direction X and Z of the frame of reference of the station and by placing and holding the transverse tool in a position that is locked in the frame of reference so that said transverse tool forms a spacer and bracing tool in the Y direction from the two parallel tools in a zone that is remote from the engine compartment of the underbody, and the method further consisting of maintaining a force (F) pressing each of the parallel tools at least against the sides of the engine compartment of the underbody while the body sides are being assembled to the underbody.
