Description

Zero position adjusting device Technical Field The application relates to the technical field of adjusting devices, in particular to a zero adjusting device. Background The actuator is used as an actuating mechanism of the ground test thrust vector control system of the carrier rocket engine and is used for generating lateral control moment according to the instruction of the control system and controlling the pitching and yaw direction swing of the spray pipe. In view of the expansion and axial elongation of the launch vehicle engine under operating conditions, actuators are typically not directly mounted to the engine. But the deformation amount of the engine needs to be considered in the installation of the actuator, so that the length of the actuator needs to be adjusted according to the deformation and extension distance of the engine in operation before the actuator is installed, namely zero adjustment operation of the actuator is performed. In the related art, three persons are usually required to cooperate to adjust the length of the actuator, wherein two persons fix two ends of the actuator, and the other person uses a central hole distance caliper to measure the length of the actuator, and after the length of the actuator is adjusted to a preset value, the extension position of the moving end of the actuator is fixed.
