Abstract

The invention provides a positioning and tightening device of a vehicle body longitudinal beam internal plate. The device comprises a positioning swing arm, a clamping swing arm and a pressing swing arm, wherein a dowel pin and an upper clamping block are mounted at the lower part of one end of the positioning swing arm; the other end of the positioning swing arm is hinged to a base; the middle part of the clamping swing arm is hinged to one part, near the dowel pin, of the positioning swing arm; springs are mounted on two sides of the upper end of the clamping swing arm; one ends of the springs are fixedly connected with the clamping swing arm, and the other ends are fixedly connected with the positioning swing arm; a pressing projection is arranged on the side wall of the clamping swing arm; one end of the pressing swing arm is hinged to the base; the lower part of the other end of the pressing swing arm is corresponding to the pressing projection; one end, hinged to the base, of the positioning swing arm is synchronously hinged to a first driving cylinder; and one end, hinged to the base, of the pressing swing arm is synchronously hinged to a second driving cylinder. The positioning and tightening device of the vehicle body longitudinal beam internal plate can automatically clamp a cover plate after positioning, is precise in positioning, has no need to singly add a procedure for welding of the cover plate, and reduces the production cost.

Description

technical field [0001] The invention belongs to the technical field of vehicle body welding, in particular to a longitudinal beam positioning fixture. Background technique [0002] like Figure 7 As shown, it is a schematic diagram of the vehicle longitudinal beam structure. Due to structural needs, a cover plate needs to be welded inside the longitudinal beam. However, due to the complex structure of the cover plate and the narrow width of the longitudinal beam, the positioning of the cover plate during welding is difficult. In the prior art, in most cases, a process is specially added for welding the cover plate. Not only the production cost is increased, but also in the narrow space inside the longitudinal beam, the positioning accuracy of the cover plate cannot be guaranteed. SUMMARY OF THE INVENTION [0003] In view of this, the present invention aims to provide a positioning and tightening device for the inner panel of the vehicle body longitudinal beam, so as to ...
