Embodiment 2
[0047] Such as image 3 and Figure 4 As shown, the present invention also provides a portable laser shock peening device with a more compact structure than that of Embodiment 1, which is easy to carry and store. In this embodiment, the laser 3 and the mechanical seal 4 are fixed on the bottom of the mechanical arm 7 On the mobile side, during laser shock strengthening, the mechanical arm 7 drives the laser 3 and the mechanical seal 4 to move synchronously, and the mechanical arm is used to directly grasp the laser and the laser transmission module, which not only realizes the dynamic adjustment of the six-dimensional direction of the output laser, but also simplifies the overall process. The optical path transmission structure of the machine laser shock peening device greatly improves the laser transmission efficiency, which is conducive to the realization of laser shock peening processing operations in multiple application scenarios.
