Abstract

The utility model discloses an export vehicle big component welding deformation control device, including framework, set up on automatic welding subassembly and water spray cooling subassembly of framework, the length direction both ends of framework are provided with the support structure symmetry, and the support structure and the framework between setting framework work height adjusting structure, the support structure is integrated with walking mechanism cooperation one end fixed establishment, this device still includes the pressure loading structure of sliding connection in the framework, and the pressure loading structure has the pressure end of compacting workpiece, when the pressure loading structure is compacted workpiece through its pressure end, and the reaction force that generates through the compacting force drives the framework and the support structure upward movement, and drives fixed establishment and walking mechanism upward movement and separates the guide rail to restrict the movement of device to reach the product quality's standard, also has greatly shortened the production cycle.
