[0002] At present, due to the development of the national economy, the improvement of living standards and the rapid development of automobile sales, automobiles have entered thousands of households. After being fixed, welding is carried out. During the processing of the outer plate of the rear wall and rear beam, due to its large volume and unevenness, it is not easy to fix and easily shift during processing operations, which affects the efficiency of processing operations. Patent No. CN207807161U discloses a rear wall The rear beam outer panel clamp is used to fix the rear wall outer panel as a whole by setting multiple pressure columns, setting the supporting surface for support, and setting multiple limit columns to limit the position, so as to complete the effective fixing of the rear wall outer panel of the car. However, the fixture is aimed at the overall fixing of the rear wall outer panel, and lacks effective fixing and positioning for the welded parts of the rear wall outer panel. During welding, the welded parts are easy to shift and affect the welding quality. Therefore, it is very important to solve this problem.
