The invention relates to the technical field of laser surface micro modeling, in particular to a laser micromachining device for the inner surface of an engine cylinder and a machining method of the laser micromachining device. An object machined by the laser micromachining device is an engine cylinder body; because the machined objects have irregular shapes, larger size and larger mass, a machining scheme that a workpiece is used for fixation and a laser head not only rotates but also takes a linear motion up and down is adopted. Through adopting the laser micromachining device disclosed by the invention, laser beams are output from an inner light path of a laser, pass through an outer light path system and then are focused by a focusing lens inside the laser head and then reflected to the machining surface of a workpiece through a total reflection mirror; and the laser outputs a single laser pulse at specified time on a specified machining point by dint of the coordination and the interaction of a numerical control system on the motion control of various axis of a work table and the single pulse output control of the laser, and therefore the laser micromachining of the surface of the workpiece is realized.
Description
technical field [0001] The invention relates to surface laser micro-texturing technology of friction pairs (Surface Laser Micro-Texturing), in particular to a laser micro-processing device and processing method for the surface of an engine cylinder. Background technique [0002] In the field of mechanical engineering, cylinder and piston ring are a typical friction pair. According to the principle of tribology, it can be known that machining the microscopic morphology conforming to the mechanism of anti-friction lubrication on the surface of the friction pair can significantly improve the lubrication performance of the friction pair and increase the service life of the friction pair. [0003] Laser surface micromodeling technology is widely used for its advantages of fast processing speed, low cost, no pollution, non-contact, no tool wear, and excellent dimensional control accuracy. The Chinese patent application publication number CN1857844A discloses a laser micro-modelin...
