Description

The invention relates to a steel ball detecting method and system, in particular to an automatic detecting system for detecting the surface of the steel ball and the physical properties of the steel ball.

In order to reduce the friction of mechanical transmission components, most of them currently use steel balls to improve the efficiency of transmission by rolling contact. Therefore, steel balls play an important role in the machinery industry. Therefore, the fineness of steel balls is very important, usually in testing. For steel balls, items that need to be measured include: surface profile, roundness, surface roughness, and fouling.

If it is known to test whether the steel balls are excellent, most of them use the artificial appearance method to detect the quality of the steel balls, that is, to detect the surface quality of the steel balls with the naked eye or with the aid of a low magnification magnifier under the light; since the human eyes observe the luminosity for a long time under the light Very high spherical surface is very prone to fatigue, and the human vision is only sensitive to the width of the defect. It is difficult to find defects such as thin and deep cracks and folds, and it is easy to miss detection. In addition, the conventional steel ball detection method can only be used.
