Aluminum alloy chassis auxiliary frame shape correction method and tool for achieving shape correction and detection

The invention relates to the technical field of shape correction tools, in particular to an aluminum alloy chassis auxiliary frame shape correction method and a tool for achieving shape correction and detection. The method has the advantages that the product is monitored in the whole process by designing the correction tool, the static tool and the detection tool in the whole process. The method comprises the following steps: 1, finding out a deformed part through structural analysis, and correcting the deformed part of the whole frame by adopting telescopic motion of a hydraulic oil cylinder; and 3, the blank is detected through an upper detection tool, whether rebound exists or not is detected, the rebounded product returns to be subjected to shape correction again, and the non-rebounded product flows downwards. Therefore, the blank qualification rate of the product can be greatly improved, waste of machining and casting resources caused by scrapping of the product due to deformation is avoided, and the cos
