ABSTRACT:
The invention relates to a straightening jig for vehicle bodies, particularly for the cabs of trucks, of the kind comprising a stand for fastening to a floor or other foundation, and being equipped with a number of bearing fixings in which a number of bearing components on a vehicle body are intended to fit and be fixed when the vehicle body is located on the jig.
The invention is characterized in that the stand is provided with guideways for at least one alignment bar which is displaceably arranged in the jig and which extends in the longitudinal direction of the jig, in that the alignment bar is provided with at least one bearing fixing in which a bearing component on the vehicle body is fitted when the vehicle body is located in the jig, in that the alignment bar is arranged so that it can carry out displacement movements in the guideways both in the longitudinal and transverse directions of the alignment bar, preferably with the aid of servo-controlled operating devices, and in that the relative position of the alignment bar in the stand can be locationally fixed when the alignment bar is moved into a given position for the bearing components of the vehicle body in the stand of the jig.
