Turbine blade opening retaining ring assembly method and assembly tool

Abstract

The application aims to provide a turbine blade opening block ring assembling method and an assembling tool. The assembling tool comprises a seat body, a driving block, a block, an elastic element and a driving unit. The seat body has an opening, the driving block is arranged in the opening and has a first inclined surface, the block is arranged in the opening and has a second inclined surface. The elastic element elastically supports the block in the opening so that the second inclined surface always matches the first inclined surface. The driving unit can drive the driving block to move in the opening along the direction from the upper surface to the lower surface. When the driving unit exerts force, the first inclined surface extrudes the second inclined surface so that the block moves towards the elastic element, the elastic element is compressed until the block part abuts against the inner periphery of the block ring, and the driving unit continues to exert force so that the block part exerts external force on the block ring. The assembling tool can reduce the local interference between the block ring and the sealing ring after assembling, thereby improving the assembling quality of the low-pressure turbine.
