Description
技术领域 technical field
本实用新型涉及一种曲轴外径检测装置。 The utility model relates to a crankshaft outer diameter detection device.
背景技术 Background technique
曲轴外径是一个很重要的加工尺寸，加工难度大，精度要求高，一般测量采用杠杆千分尺，但是由于工人技术水平有限，测量误差很大，不能保证大批量产品的合格率。而使用测长仪，因为效率问题又不能大批量测量，而且耗时长，不能及时反馈，不利于加工现场的控制。 The outer diameter of the crankshaft is a very important processing dimension, which is difficult to process and requires high precision. Generally, a lever micrometer is used for measurement. However, due to the limited technical level of workers, the measurement error is large, and the pass rate of mass products cannot be guaranteed. However, the use of length measuring instruments cannot be measured in large quantities due to efficiency issues, and it takes a long time and cannot be fed back in time, which is not conducive to the control of the processing site.
