Description
Technical Field
The invention relates to a laser shock peening system, and belongs to the technical field of laser shock peening.
Background
Laser shock peening is an advanced technique for modifying the surface of a material by using shock waves induced by intense laser. The technique utilizes short pulse (< 10 ns), high peak power density (> 1GW/cm 2) laser light through a transparent constraining layer to act on an absorbing layer coated or attached to the surface of the workpiece. The absorption layer absorbs laser energy and expands rapidly to generate GPa-level shock waves which are transmitted to the interior of the material, so that the dislocation density of the surface layer of the material is increased, crystal grains are refined, and residual compressive stress is formed, thereby improving the fatigue resistance, corrosion resistance and other properties of the material. At present, the laser shock peening technology has been widely applied in the fields of aviation, ships, mechanical engineering and the like.

For the impact reinforcement of complex parts or parts of different types, one path or even two paths of laser are difficult to meet the requirements, and the laser processing heads with different functions are usually required to be disassembled and replaced as shown in fig. 2, however, the laser processing heads are complex and heavy in composition and difficult to replace, so that time and labor are wasted, large-scale and high-efficiency production and application are difficult to realize, and the industrialization process of the technology is hindered; secondly, laser shock peening belongs to the high-energy laser application field, has very high strict requirements on the temperature, the humidity and the cleanliness of a laser device, a space transmission light path and the interior of a laser processing head, and quality accidents easily occur in the process of dismounting the laser processing head and optical components, so that professional personnel must operate the laser shock peening in person, and the use difficulty of the technology is increased to a certain extent. In addition, existing laser shock peening systems lack a user friendly design in controlling use. An integral system comprises a laser, a space transmission light path, a laser processing head and a mechanical movement mechanism, and each part has an independent control interface at present, so that the interconnection and the intelligence level are lacked, production accidents are easy to occur, and the large-scale and high-efficiency production application is not facilitated.
