Three-dimensional detection method of plateau honing cross hatches in inner hole of cylinder liner

Abstract

The invention relates to a three-dimensional detection method of plateau honing cross hatches in inner hole of a cylinder liner. Developing image analysis, feature recognition and digital processing technology lay good foundation for the development of surface roughness measurement and provide capacity of surface three-dimensional analysis. The method is characterized in that: three-dimensional parameters are acquired from regional surface rather than from profile track; statistic information exacted by three-dimensional analysis has high robustness and reliability; the advantages of excellentstatistic property, small error; and the like are achieved, and parameter values can reflect a real surface state.

Description

technical field [0001] The invention relates to a three-dimensional cylinder liner inner hole platform honing texture detection method, with the development of image analysis, feature recognition and digital processing technology, it provides a technical basis for the development of surface roughness measurement, and the ability to perform three-dimensional analysis on the surface . The 3D parameters are obtained from the regional surface rather than the contour trajectory. The statistical information extracted by 3D analysis is more robust and reliable, and has the advantages of good statistical properties and small errors, so that the parameter values ​​can reflect the real state of the surface. Background technique [0002] The current internal combustion engine cylinder liner inner hole platform honing technical specifications and testing methods are still industry standards issued in 1999. Ten years later, its content and requirements can no longer meet the needs of the...

Problems solved by technology

Various OEMs and production enterprises put forward a lot of their own evaluation requirements, resulting in many and complicated requirements for platform honing anilox technology, forming a mutually closed situation, which limits the exchange and development of the industry to some extent

[0003] The current technical specifications and detection methods are mainly based on the traditional two-dimensional profile, and the main measurement indicators are the current standard parameters, which cannot meet the diverse requirements of customers. At the same time, they cannot describe the geometric structure characteristics of the surface in detail, and cannot be reflected by the surface morphology features. process problems
