Embodiment Construction

[0005] During rough honing, the macroscopic shape of the inner hole of the cylinder liner is determined, and the consistency of cylindricity and margin must be ensured to provide a basic surface for laser shaping.

[0006] According to the performance requirements of the engine, the type of laser sculpted structure is selected.

[0007] Laser shaping is performed after adjusting the reciprocating and rotating speeds of the laser, light guide system, laser output head and spindle.

[0008] Fine honing is mainly to remove the burrs after laser forming and improve the surface roughness of the inner wall of the cylinder liner.

Abstract

The invention provides an application of a laser honing technology in a cylinder liner of an ocean engine, which combines laser and the honing technology and causes the final processing of the surface of the cylinder liner to comprise three procedures, namely, rough honing, laser forming and fine honing; a platform reticulate pattern after laser honing has even deep grooves and uniform width and interval, thus building an oil lamella on the surface of a platform and having good lubricating effect; the deep grooves have the function of storing engine oil and releases the engine oil for lubricating friction timely; meanwhile, the platform supports the motion of a piston ring and meets the requirements of high abrasive resistance and low emission.

Description

technical field [0001] The invention relates to the application of a laser honing technology in an ocean-going engine cylinder liner, which is especially suitable for the configuration of a large-scale ocean-going ship engine and meets the requirements of high wear resistance and low emission. Background technique [0002] At present in the world, honing is the method used for the final processing of the working surface of the engine cylinder liner. Usually, secondary honing (rough honing and fine honing) or triple honing is performed after fine boring, that is, platform honing is performed on the basis of secondary honing. From a tribological point of view, platform textures, which are more expensive and difficult to control, are preferred. The general platform honing method will inevitably have non-uniformity, so it is difficult to pre-calculate the matching situation related to the engine. So far, the possibility of improving the surface profile shape and further tighte...
