车床挂挡拨叉作为车床换挡机构中关键零件,对尺寸和形位误差要求严格。针对现有测量技术在测量车床挂挡拨叉时的局限性,设计了一种结构简单、使用方便、能同时检测4个待测项目的综合检测装置。该装置提高了检测精度和检测速度,具有很好的实用价值。 Lathe hanging gear fork as a key part of the lathe shift mechanism, the size and shape of the error-bit strict requirements. In view of the limitation of the existing measurement technology in measuring the gear block of the lathe, an integrated detecting device with simple structure and convenient operation, which can test 4 items to be tested at the same time, is designed. The device improves the detection accuracy and detection speed, has good practical value.
