AI Technical Summary

Technical Problem

[0002]现有经过加工的零件中，存在零件的内形为两段“卵形”腔体连接而成，通常采用数控车床加工成型，而内形中众多的半径圆弧尺寸则很难进行检测，且无法使用内径千分尺、三坐标进行检测；若要保证产品的加工质量，所有尺寸都必须进行100%检验合格才能使用

Benefits of technology

[0014]The beneficial effects of this utility model are as follows: This utility model adopts a path formed between the power supply and indicator light in conjunction with the detection block, resulting in high measurement accuracy, which depends on the machine tool accuracy, the accuracy of the probe itself, and its repeatability; high measurement efficiency, allowing for rapid measurement before, after, or during processing, significantly reducing machine tool downtime; low risk, with timely adjustments possible in case of problems. Furthermore, it can detect the full arc segment dimension of the workpiece's inner surface in real time, truly achieving the requirement of 100% dimensional detection. For parts with single or multiple continuous "oval" inner cavity arc dimension structures, this method offers a simple, scientifically sound, and low-cost approach for detection, becoming a universal detection method.
