Large thin-wall ceramic matrix composite part machining deposition tool, machining method and using method
The invention provides a large thin-wall ceramic matrix composite part machining and depositing tool, a machining method and a using method. The problems that in the machining and depositing process of a large thin-wall ceramic matrix composite part, limiting is not firm, and the control precision is poor are solved. The processing deposition tool comprises two graphite molds which are the same in shape and structure, and a plurality of sewing holes are formed in the graphite molds; the sewing holes are divided into cylindrical holes and two-section holes, 5%-8% of the sewing holes are the two-section holes, the ends, close to the outer surface of the graphite mold profile body, of the sewing holes are conical holes, and the ends, away from the outer surface of the graphite mold profile body, of the sewing holes are the cylindrical holes; a graphite support pin can be correspondingly placed in each conical hole, the tail part of the graphite support pin is a conical body, is positioned in the conical hole and is matched with the conical hole in shape, and the head part of the graphite support pin extends out of the conical hole and is a spherical body in shape; and the conical surface line of the conical body is tangent to the spherical surface of the spherical body. Meanwhile, the invention further provides a machining method and a using method of the tool.
本发明提供了一种大型薄壁陶瓷基复合材料件加工沉积工装及加工方法和使用方法，解决了大型薄壁陶瓷基复合材料件在加工沉积过程中限位不牢靠、控制精度差等问题。本发明中加工沉积工装包括两个形状、结构相同的石墨模具，石墨模具上设有多个缝制孔；所述缝制孔分为柱形孔和两段孔，缝制孔中的5％～8％为两段孔，靠近石墨模具型面体外表面一端为锥形孔，远离石墨模具型面体外表面一端为柱形孔；每个锥形孔内可对应放置一个石墨支撑稍，所述石墨支撑稍的尾部为锥形体，位于锥形孔内，形状与锥形孔的形状相适配，石墨支撑稍头部伸出锥形孔的外部，形状为球面体；所述锥形体的锥面线与球面体的球面相切。同时本发明还提供了上述工装的加工方法和使用方法。
