The attitude and orbit control gas valve group is a key component for controlling the attitude and orbit control engine to realize attitude control and orbit adjustment in the flight process of the aircraft. The control ability of the attitude and orbit control gas valve group has an important influence on the performance of the attitude and orbit control engine, so the mechanical movement of the attitude and orbit control gas valve group must meet the rapid and accurate response effect, so as to rapidly and accurately adjust the attitude control system such as pitch, yaw and roll of the engine and the trajectory control system of lateral maneuvering flight. The mechanical movement of the attitude and orbit control gas valve group refers to the linear movement of two groups of four valve core assemblies arranged in a cross shape in the attitude and orbit control gas valve group, and the movement of the two groups of valve core assemblies is controlled to realize the correction of the attitude and orbit of the attitude and orbit control engine.

[0003] In the assembly process of the attitude and orbit control gas valve group, the valve core assembly movement is generally driven by an electric control comprehensive test platform, and the movement stroke of the valve core assembly is measured by a depth micrometer to determine whether the attitude and orbit control gas valve group meets the design index requirements. However, the manual measurement of the valve core assembly stroke by the depth micrometer has the following problems: the measurement is inaccurate due to the deformation of the depth micrometer caused by the impact force of the valve core assembly movement; the measurement error caused by the reference deviation is large; the valve core assembly stroke in four directions is completed in four times, the efficiency is low; and the measured data needs to be recorded manually.
