舵梁耳片孔同轴度是零件重要的形位公差。为保证零件同轴度要求,设计了由菱形销、圆柱销和平面支承组成的定位工装,并采用组合衬套和可拆卸引导装置等结构设计,满足了各项工艺要求。
The rudder beam hole concentricity is an important part of the form of tolerances. In order to ensure the concentricity of the parts, a positioning tooling consisting of rhombic pins, cylindrical pins and plane supports was designed. Structural design such as combination bushing and detachable guiding device was adopted to meet various technological requirements.
