[0007] Due to the characteristics of ultra-short pulse and ultra-high energy density, femtosecond laser has the characteristics of less damage to materials, good processing quality and fast processing speed when using femtosecond laser for material processing. At present, there are femtosecond laser processing Technology research on the inner surface of the cylinder, Wenzhou University declared "a method and device for the inner surface of the laser composite micro-textured cylinder liner" (201310013106.0), developed a laser composite micro-textured inner surface of the cylinder liner In this method, the required micro-texture structure is firstly obtained by femtosecond laser processing. The femtosecond laser processing area on the inner surface is subjected to impact strengthening treatment, thereby enhancing the mechanical properties of the material in the femtosecond laser processing area; however, compared with other traditional commonly used lasers, the femtosecond laser is very expensive, and currently the femtosecond laser is used for correlation. The industrial production of products, from the perspective of economy and production cost, is still far from meeting the requirements

[0008] In order to obtain higher processing efficiency and produce deep enough oil storage micro pits, there are also related technologies that use two or more lasers in parallel to improve processing efficiency and speed; Wuhan Kairuidi Laser Technology Co., Ltd. Announced a "Solid Laser Honing Device" (203265910U), which uses two or more pulse train solid-state lasers connected in parallel to a solid-state laser honing device, through which a higher teaching efficiency can be obtained and a sufficiently deep However, the "solid laser honing device" honing machine uses a two-dimensional translation guide rail to control its movement and positioning. This structure requires a lot of time wasted in clamping and processing positioning of the cylinder set, and every When changing a cylinder liner for processing, it is necessary to re-position the processing, which greatly increases the processing preparation time and is not conducive to improving production efficiency
