This paper aims to study questions about the thread cone angle of the cone lock-pin synchronizer used in the gearbox of a vehicle model, such as unstable measurement accuracy and single quality control method. This thesis introduced the basic working method of the equipment for testing the thread cone angle developed according to the tangent trigonometric function. The experimental data reported that the limitation and unreasonableness in the design of its original measuring mechanism were the main reasons that the measurement accuracy was unstable. Therefore, we selected another angle measuring scheme, that is, to develop new test equipment using the method of calculating the radian and then rotating the angle, and optimize the structure of mechanical measuring head to improve the measurement accuracy and reliability of the synchronizer’s thread cone angle, finally realizing that the processing quality of synchronizer parts was under control.
