飞机零零部件中往往或多或少都有不同程度型面,主要集中在各种连接接头、对接接头、角盒、推力座、连接座等。其形式有单向型面、双向型面、复合型面、组合型面等,型面的精度也随零件的装配关系或技术要求而高低不一。该文根据型面加工的特点和类型,结合实践和总结,给出了在型面加工的流程及注意要点,通过对实例的步骤分析,给出了详细生产过程和注意事项。事实证明,作者摸索出的这些方法和经验,在实际生产中是行之有效的,能够很好地保证零件的产品质量和大大提高了加工进度。
Aircraft parts often have more or less different degrees of profile, mainly in a variety of connectors, butt joints, corner boxes, thrust seat, connecting seat and so on. The form of one-way surface, two-way surface, composite surface, the combined surface, the accuracy of the surface with the assembly of parts or technical requirements of different levels. According to the characteristics and types of surface machining, this paper gives the process and points of attention in the surface machining with the practice and conclusion. Through the analysis of the steps of the example, the detailed production process and precautions are given. Facts have proved that the authors explore these methods and experience in the actual production is effective, well to ensure the quality of parts and products greatly improve the processing progress.
