Method for making a motor car body

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 at least one transverse tool ( ) extending transversely to said parallel tools, the three tools being connected to one another and to the X, Y, Z frame of reference of the station in such a manner that the transverse tool ( ) is placed and held in a position that is precise and locked in the frame of reference and that it forms a spacer and bracing tool in the Y direction for the two parallel tools ( ) in a zone that is remote from the engine compartment ( ) of the underbody ( ); and in 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.
