Abstract

An installation for assembly and in particular for pinning the car bodies of motor vehicles, includes carriages for supporting the car bodies to be assembled by welding, and a conveyor track for displacing these carriages to an assembly station provided with welding equipment. The installation is characterized in that it includes a rigid and fixed stand, a rigid frame which reciprocates on the stand, and at least two gantry structures rigidly fixed to the frame, each gantry having apparatus for positioning and holding a particular model of car body to be welded, apparatus for reciprocating the frame on the stand in a direction parallel to the displacement of the carriages, and apparatus for locking the frame in relation to the stand so as to position one or other gantry in the assembly station.

Claims

1. Installation for the assembly and in particular for the pinning of car bodies of motor vehicles comprising carriages for supporting the car bodies which are to be assembled by welding, and means for displacing said carriages to an assembly station provided with welding equipment, said installation comprises a rigid and fixed stand, a rigid frame which reciprocates on the stand in a direction parallel to the movement of the carriages and at least two gantries rigidly fixed to said frame, each said gantry comprising positioning and holding means for a particular model of car body to be welded, means for reciprocating the frame on the stand in a direction parallel to displacement of the carriages and means for locking the frame in relation to the stand so as to position one of the gantries in the assembly station.

2. Installation according to claim 1, characterised in that the means for displacing the carriages are arranged in the interior of the stand and of the frame parallel to the sense of displacement of the frame on this stand.

3. Installation according to claim 1, characterised in that each gantry supports welding equipment.
