With longitudinal keyway so as to latticed keyway arrangements are formed on base plate, blade locking device, blade holding device and blade are surveyed
Amount model component is respectively installed in the latticed keyway arrangements, for difference by positioning key and slotted cheese head screw
The overall length detection of the fixed blade of steam turbine diaphragm piece of size only needs to adjust the survey of blade locking device, blade holding device and blade
Relevant position of the amount model component in backplane mesh shape keyway arrangements, can meet detection and require, therefore it greatly improves survey
The versatility of tool, can effectively reduce frock cost；Equidistantly open between its adjacent transverse keyway, between adjacent longitudinal keyway
If, and the equal setting of spacing between the spacing between adjacent transverse keyway and adjacent longitudinal keyway, can be in base plate chi
It is very little it is certain in the case of expand the adjustable extent of blade locking device, blade holding device and Blade measuring model component,
Its versatility is improved further.
