The contour rotation half-turn of standard cylinder (40) is to obtain measurement circular curve (401)；
The measurement circular curve (401) is compared whether in the upper deviation circular curve (402) and the lower deviation circular curve (403)
Between, if the measurement circular curve (401) the 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 measuring head (10) more renewed.
8. Blade measuring instrument self checking method according to claim 7, which is characterized in that
The Blade measuring instrument self checking method further includes using measuring head (10) described in the Blade measuring instrument self-test tooling self-test
Mounting height deviation whether within the allowable range, specifically includes the following steps:
Start the Blade measuring instrument and be moved to the measuring head (10) after setting height and is moved to the Blade measuring instrument again
At the drift slot (501) of self-test tooling, it is smooth by described to continue to translate the measuring head (10) such as described measurement ball (11) energy
Drift slot (501) then the measuring head (10) mounting height deviation within the allowable range, otherwise, finely tune the measuring head (10)
Height keep the measurement ball (11) smooth by the drift slot (501).
9. Blade measuring instrument self checking method according to claim 8, which is characterized in that the Blade measuring instrument self checking method
Further include using the Blade measuring instrument self-test tooling to not by the measuring head (10) self-test of the drift slot (501) with
The actual height deviation of the measuring head (10) is obtained, specifically includes the following steps:
The dial plate (642) of the amesdial (64) for the Blade measuring instrument self-test tooling that returns to zero is to zero groove；
The lower section of the measuring head (10) extremely amesdial head (641) of the Blade measuring instrument self-test tooling is translated to support upwards
The amesdial head (641)；
Read the numerical value of the amesdial (64), actual height deviation=dial plate (642) of the measuring head (10)
Show value ﹣ precompressed tabular value.
