Fuel gas nozzle adjusting device and method for solid orbit control engine

The invention discloses a fuel gas nozzle adjusting device and method for a solid orbit control engine, and aims to adjust the angle of a fuel gas nozzle by taking an engine cabin as a reference through the fuel gas nozzle adjusting device, improve the position precision of a thrust axis of the orbit control engine and realize accurate control of the orbit control engine. The structure comprises a spray pipe, a connecting flange, a base, a spherical column, an end cover, a positioning tool, a positioning core rod, a cabin body, an O-shaped ring, a fastening screw, a fixing screw and a positioning pin. The layout form is shown in the attached drawing, an orbit control engine spray pipe is fixed to the connecting flange through threads, the positioning tool and the cabin body are positioned through the two positioning pins and fixed through the two fixing screws, it is guaranteed that the angle of a gas nozzle is adjusted in place through the positioning tool and the positioning core rod, and the spherical colu
