轴承内圈内径加工精度统计质量监控系统的研究

Statistical Quality Monitoring System for the Machining Precision of the Internal Diameter of Bearing Inner Ring

为克服过去采用非数字化仪表测量易产生的读数误差等问题,设计开发了轴承内圈内径加工精度统计质量监控系统,提高了轴承内圈内径的质量检验效率,保证了轴承内圈的产品质量。该系统主要包括检测装置、数字量表、采集接口和微型计算机4个部分,其中检测装置可满足轴承内圈内径全系列的要求。

The statistical quality monitoring system for the machining precision of the internal diameter of hearing inner ring is developed,to overcome the shortcomings in non-digital instrument measurement,such as reading-error and so on. This systern is used to improve the test efficiency and ensure the quality of bearing inner ring. It includes four parts： test apparatus,digital instrument,acquisition interface and microcomputer. The test apparatus can ensure the rest of all bearing inner rings.
