Whole ring machining tool and method for SiC/SiC ceramic matrix composite turbine blade
The invention relates to a turbine blade assembly tool and method, in particular to a SiC/SiC ceramic matrix composite turbine blade whole ring machining tool and method. The technical problem that when an existing SiC/SiC ceramic matrix composite turbine blade is assembled into a whole ring, the consistency of the size and the molded surface is poor is solved. The tool comprises a front face machining tool and a back face machining tool. The front face machining tool comprises a front face base, a plurality of first pressing pieces, a supporting ring and a first pressing plate. The front base is provided with a cylindrical boss; the supporting ring is arranged on the outer surface of the cylindrical boss in a sleeving mode, and the reference boss is tightly pressed through the first pressing plate and the supporting ring; the first pressing sheet is used for pressing the third boss on the front base; the back face machining tool comprises a back face base, a fastener, a second pressing plate and a plurality of second pressing pieces. A cylindrical boss is arranged in the center of the reverse base; the second pressing plate is arranged on the upper end face of the cylindrical boss and used for pressing the reference boss through a fastener. And the second pressing sheet is used for pressing the second boss on the reverse base.
本发明涉及涡轮叶片装配工装及方法，具体涉及一种SiC/SiC陶瓷基复合材料涡轮叶片整环加工工装及方法。解决了现有SiC/SiC陶瓷基复合材料涡轮叶片组装成整环时，存在尺寸及型面一致性较差的技术问题。本发明工装包括正面加工工装和反面加工工装；正面加工工装包括正面底座、多个第一压片、支撑环和第一压板；正面底座设置有圆柱凸台；支撑环套设在圆柱凸台外表面，第一压板和支撑环将基准凸台压紧；第一压片用于将第三凸台压紧在正面底座上；反面加工工装包括反面底座、紧固件、第二压板和多个第二压片；反面底座中心设置有圆柱凸台；第二压板设置在圆柱凸台上端面，用于通过紧固件将基准凸台进行压紧；第二压片用于将第二凸台压紧在反面底座上。
