8. a kind of Blade measuring instrument self checking method, it is characterised in that using the blade as any one of claim 1 to 7
The degree of wear of the measurement ball (11) of measuring instrument self-inspection frock self-inspection Blade measuring instrument whether in allowed band, specifically include with
Lower step：
The Survey Software of the Blade measuring instrument is run with according to the standard cylinder (40) of the Blade measuring instrument self-inspection frock
Standard circular curve draw the standard round Curve Machining abrasion upper deviation value after upper deviation circular curve (402), the standard round
Curve is plus the lower deviation circular curve (403) after abrasion lower deviation value；
Start the Blade measuring instrument make two described measurement ball (11) conflict standard cylinder (40) cylindrical after along described
The contour rotation half-turn of standard cylinder (40) is to obtain measuring circular curve (401)；
Measurement circular curve (401) is compared whether in upper deviation circular curve (402) and the lower deviation circular curve (403)
Between, if measurement circular curve (401) upper deviation circular curve (402) and the lower deviation circular curve (403) it
Between, then the degree of wear of measurement ball (11) is in allowed band, otherwise, the measurement head (10) that more renews.
9. Blade measuring instrument self checking method according to claim 8, it is characterised in that
The Blade measuring instrument self checking method is also included using measurement head (10) described in the Blade measuring instrument self-inspection frock self-inspection
Setting height(from bottom) deviation whether in allowed band, specifically include following steps：
Starting the Blade measuring instrument makes the measurement head (10) move to the Blade measuring instrument again after being moved to setting height
Drift groove (501) place of self-inspection frock, continuing such as described measurement ball (11) of translation measurement head (10) can be smooth by described
Then described measurement head (10) the setting height(from bottom) deviation of drift groove (501) otherwise, is finely tuned measurement head (10) in allowed band
Height make measurement ball (11) can be smooth by drift groove (501).
10. Blade measuring instrument self checking method according to claim 9, it is characterised in that the Blade measuring instrument is from procuratorial organ
Method is also included using the Blade measuring instrument self-inspection frock to not by the measurement head (10) self-inspection of drift groove (501)
So that the actual height deviation of the measurement head (10) is obtained, following steps are specifically included：
The dial plate (642) of the amesdial (64) of the Blade measuring instrument self-inspection frock that returns to zero is to zero groove；
The lower section of amesdial head (641) of the measurement head (10) to the Blade measuring instrument self-inspection frock is translated to support upwards
Amesdial head (641)；
The numerical value of the amesdial (64) is read, actual height deviation=dial plate (642) of measurement head (10)
Show value precompressed tabular value.
