超高精罗拉轴毛坯件的自动综合检测系统

Automatic inspection system for super high-quality roller blank

为了提高超高精罗拉的生产效率,根据两点法和相对测量理论,提出了一种超高精罗拉轴毛坯件的自动综合检测系统。其硬件系统采用直接接触式测量方式,通过杠杆机构实现零件表面信息的采集。软件系统应用模块化设计思想,能实现零件的在线测量、检测数据自动记录、零件分选、参数调整、统计分析等功能。系统能一次检测且能自动获得罗拉毛坯件的5个截面直径和直线度,系统误差为±0.7μm。经多批次随机抽样50件检验,将自动检测和手工检测结果相比较,二者重合度很好,每根检测时间为20 s。

A super high-quality roller blank automatic inspection system has been proposed according to the two point method and relative measure theory for production efficiency improvement. The hardware system adopts the direct contact measure way, affecting the collecting of surface information of the roller blank by means of the lever mechanism. And the modularization design has been applied in the software system to accomplish online measurement, automatic datum recording, part distinguishing, parameters updating, statistic and analysis. The system can achieve 5 sectional diameters and straightness in one inspection, and its error is ± 0.7 μm. Based on inspection of 50 blanks by random sample in many lots, the results obtained by the automatic inspection system are in good agreement with those by manual operations. The automatic inspection system can finish inspection of one blank within 20 seconds.
