AI Technical Summary
Technical Problem
In the maintenance of existing turbine blades, the balance test fails due to the difference in weight and center of gravity between new and old blades, which requires repeated disassembly of rivets and adjustment of blades, increasing costs and time.
Method used
New and old blades are temporarily fixed with rivets. First, the new blades are ground to the size of the old blades, then the rivets are removed. Combined with balance measurement and adjustment, the blade installation positions are ensured to be consistent.
Benefits of technology
It improved the repair success rate, reduced the waste of expensive original rivets, and decreased the number of rework attempts and economic costs.

Abstract
本申请公开了一种涡轮维修方法及装置，涉及航空维修技术领域。所述方法包括：通过拉铆钉将新涡轮叶片安装在涡轮盘上；通过拉铆钉将旧涡轮叶片安装在所述涡轮盘上；磨削所述新涡轮叶片至所述旧涡轮叶片的尺寸；拆卸所述拉铆钉。本申请通过采用拉铆钉双面操作临时固定叶片，替代了使用原厂压接铆钉，减少了昂贵的原厂铆钉的浪费，同时结合新叶片先磨削后拆卸的流程，使得新叶片磨削后尺寸与旧叶片一致，避免了平衡测试不通过导致的返工，有效解决了现有涡轮维修中因新旧叶片重量差异大而需反复拆卸铆钉、调整叶片的问题，从而显著提高了维修成功率并降低了成本。
