In the design of the transmission, according to the size requirements of the installed bearings, the length dimension tolerance from the end face of the input shaft circlip groove to the large end face is 0.06mm. Usually, the detection of the length and dimension of shaft parts is directly through the altimeter, with the large end face as the reference, collecting points in the circlip groove to measure the length and dimension of shaft parts. However, due to the complex operation of the altimeter, online detection cannot be realized, and it cannot meet the needs of mass production. Generally, the measurement reference plane of the input shaft is a circular arc surface. According to the conventional plug plate design idea, the length distance from the end face of the circlip groove of the input shaft to the large end face cannot be accurately measured. The detection device is required to be operable and simple. At the same time, the structure of the inspection fixture is required to be simple and the requirements for the industrial environment are not high.

The end face of the circular arc through end can enter the circlip groove, and the end face of the circular arc stop end cannot enter the circlip groove to stop, and the part is judged to be qualified, otherwise it is unqualified. Therefore, it is possible to quickly detect whether the length dimension of shaft parts is qualified or not. The device has the advantages of accurate detection, simple operation, low cost and light weight, and is widely applicable to the popularization and use of on-line measurement.

Further, since the section of the inspection tool body is L-shaped, it is possible to observe the measurement situation intuitively and conveniently,
