Displacement machine and system for laser shock peening and laser shock peening method

The invention relates to a positioner and system for laser shock peening and a laser shock peening method, a rotary driving mechanism and two roller supporting mechanisms are all installed on a base, the rotary driving mechanism is installed on one side of one roller supporting mechanism, two clamps are installed on the two roller supporting mechanisms respectively, and the two clamps are installed on the base. The two clamps are used for clamping a workpiece, the rotating disc is installed on the rotating driving mechanism, one end of the universal shaft is connected with the rotating disc, the other end of the universal shaft is connected with one of the clamps, the rotating disc is used for driving the universal shaft to rotate under the condition that the rotating driving mechanism is started, and the universal shaft drives the clamps and the workpiece to rotate. The laser shock peening device is applied to laser shock peening and used for solving the problem that installation is difficult when a large wo
