通过对叶栅试验件数控铣加工及组件装配工艺的改进研究,对传统加工工艺及组件装配工艺进行优化,选用三坐标加工中心加工叶片端面及榫头,保证了榫头的一致性;在榫头加工螺纹孔,利用螺栓穿过榫槽将叶片与栅板固定,解决了叶栅试验件组件装配尺寸问题。此方法可大幅减少加工时间,提高零件合格率。 Through the research of numerical control milling process and component assembly process of cascaded test pieces, the traditional machining technology and component assembly process are optimized. The machining of the blade end face and tenon by the three-coordinate machining center is adopted to ensure the consistency of the tenon. Holes, bolts and bolts through the tongue and the grid plate will be fixed to solve the cascade test assembly assembly size problems. This method can significantly reduce the processing time and improve the passing rate of parts.
