The tenon of processing blade 15 is close and is tightly attached to the tenon side of blade 15 to be processed, to grip blade 15 to be processed
Between locating piece 6 and pressing plate 2, left hand jiggles headgear 16, judges whether blade 15 to be processed clamps.Blade 15 to be processed
After clamping, gauge stand 19 is placed on calibrating rack 22, the tip of measuring rod 18 is contacted with the upper surface to table pin 23, adjusts tabular value
To zero.Blade 15 to be processed is fixed on device by above-mentioned operation and after dial gauge or the correction of amesdial tabular value, will be measured
Bar 18 is inserted into the first guide rail 7-1 of first pair of table block 7, and the measurement head of measuring rod 18 is contacted with 16 outer surface of headgear, from upper past
Lower slider, observation and record tabular value, if tabular value variation in the margin of tolerance of headgear position, illustrates that the position of headgear 16 is closed
Otherwise lattice illustrate there is deviation in intake and exhaust edge direction, unqualified；Then measuring rod 18 is being inserted into the of second pair of table block 8 again
In two guide rail 8-1, the measurement head of measuring rod 18 is contacted with 16 outer surface of headgear, is slided from top to bottom, is observed and record tabular value, such as
Fruit tabular value changes in the margin of tolerance of headgear position, then illustrates that the position of headgear 16 is qualified, otherwise illustrate in leaf basin, blade back side
It is unqualified to there is deviation.
After being measured, if 16 position of headgear is qualified, subsequent handling, the i.e. blade tip to blade 15 to be processed are carried out
Band headgear is carried out to pour into a mould；If 16 position of headgear is unqualified, need to unload on headgear 16, adjust position after again by headgear 16 with
The blade tip position cast connection of blade 15 to be processed, then position measurement is carried out, until reaching headgear position qualification, then carry out follow-up
Process.
Blade to be processed 15 with headgear 16 is clamped to and measures in tooling by the present invention, by dial gauge or amesdial
Measuring rod 18 is inserted into guide rail, and measurement head is contacted with the outer surface of headgear 16, and measuring rod 18 is being kept outside measurement head and headgear 16
Surface contact under conditions of slided up and down along guide rail, observe the variation of tabular value, if tabular value in the margin of tolerance of headgear position,
Then illustrate that 16 position of headgear is qualified, if exceeding the margin of tolerance, illustrates that headgear 16 tilts, position is unqualified, needs at this time
Headgear 16 is unloaded and is poured into a mould again.Therefore, whether the position of the invention that can measure headgear 16 is qualified, when finding unqualified again
Cast to improve the qualification rate of 16 position of headgear, and then improves the qualification rate for the blade subsequently poured into a mould.And it will be to be processed
The fixed form that blade 16 is placed vertically, measurement error caused by effectively preventing terrestrial gravitation improve die forging rotor blade
The qualification rate that headgear position measures, and then improve the consistency of die forging rotor blade headgear cast.
