一、说明由于钢球在球轴承中是点状承载,故其表面的缺陷如裂纹,条状机械伤及锈蚀等,对轴承的质量和性能都有着很大影响。尽管这些缺陷的种类和数量随着钢球加工工艺水平的不断提高和稳定而相对减少,但要想全部通过加工来保证质量仍是困难较多,故钢球表面缺陷的检验仍是当前生产线上的一个重要工序。目前,这一工作主要还是靠人的肉眼来进行,这不仅占用了大量人力,而且人眼的视力是有限的,往往会由于误漏检而无法确保工件质量。因此自1958年以来,我国就有不少单位在球的表面质量自动检验方
First, that ball bearings in the ball bearing is punctate, so the surface defects such as cracks, bar-like mechanical injury and corrosion, the bearing quality and performance have a great impact. Although the type and quantity of these defects are relatively reduced with the continuous improvement and stabilization of the steel ball processing technology, it is still more difficult to ensure the quality of the steel ball by machining. Therefore, the inspection of the surface defects of steel balls is still the current production line An important process. At present, this work is still mainly by the naked eye, which not only takes up a lot of manpower, but also limited human eyesight, often due to error detection and can not ensure the quality of the workpiece. Therefore, since 1958, there are quite a few units in our country where the surface quality of the ball is automatically checked
