Description
Technical field
This utility model relates to the processing tool field of turbine blade, is specially the scalable leaf top Finial device of a kind of Turbine with Long Blades.
Background technology
Turbine with Long Blades typically refers to the length blade more than 900mm in turbomachinery, the middle part of blade, often with damping boss, is characterized in that boss is with fine down to blade root position rigidity, generally will not be deformed, and more than boss very poor to leaf top bit rigidity, deform often very big.
The course of processing of Turbine with Long Blades is, makes a call to two centre bores at the blade root position of blade forging blank, and leaf top bit makes a call to a centre bore, by three centre bore location of blade blank, processing blade profile, then blade profile is carried out square chest pre-determined bit, by square chest location processing blade root. Owing to boss is with upper bit poor rigidity, thus the deformation of this partial blade profile is very big, after causing that blade profile machines, the position of leaf top centre bore has deviated from original blade center line position, and owing to deformation is uncontrollable, the deviation value of every blade and blade top centre bore is different, if re-using original forging blank Shang Yeding center, being equivalent to blade slant setting in the axial direction, this is unallowed in turbine blade processing. Existing Ye Ding center holding device is as shown in Figure 1, its position of top 10 cannot carry out the adjustment in other directions except producing axial displacement again to hold out against leaf top centre bore, therefore to ensure the clamping position of blade, leaf top centre bore can only be beaten again, this be accomplished by first passing through beat straight pin and welding by vexed for original centre bore fall, then go up drill jig and beat again centre bore, the position in inspection center hole again, if being unsatisfactory for requirement, in addition it is also necessary to again beat again centre bore, waste time and energy very much.
