Deformation correction tool

The utility model aims at providing a deformation correction tool to solve the problem that the flatness of the bottom of a workpiece cannot be guaranteed due to upward rebound of a position to be corrected caused by small downward pressing deformation of a downward pressing correction assembly in the prior art. The deformation correction tool comprises a correction platform and a mounting frame, and a pressing correction assembly is arranged on the mounting frame and is of a hydraulic or pneumatic or electric structure. Cushion blocks used for supporting the two ends of a to-be-corrected part in a workpiece are arranged on the correction platform, the tops of the cushion blocks are provided with supporting faces, and the supporting faces are located above the table top of the correction platform so as to increase the distance between the to-be-corrected part and the table top of the correction platform. Or the correction platform is provided with a groove, the correction platform is provided with a table top
