Degree is required in standard, is calculated the support body to the distance F of weld seam according to the requirement of the standard of elliptic imaging, is recycled institute
The support body is fixed on the article to be measured by the screw rod fixture for stating support body bottom, thus can directly be carried out lossless
It has detected, only need to remember translation distance F when clapping first photo, only needed according to distance F when weld seam below is detected a flaw
The support body is fixed on the article to be measured, detection efficiency and the egative film qualification rate is thus greatly improved.
In order to further improve performance of the present utility model, diameter big ten milli of the retainer ring than the stem pipe
Rice.
In order to further improve performance of the present utility model, the height of the support body is in 600 millimeters and 700 millimeters
Between.
In order to further improve performance of the present utility model, the width of the screw rod fixture is 100 millimeters.
In order to further improve performance of the present utility model, the screw rod fixture and the support body nested encryptions, institute
State support body and the crossbeam nested encryptions.
In order to further improve performance of the present utility model, the crossbeam is fixedly connected with the retainer ring.
In order to further improve performance of the present utility model, the exposure source electrically connects with the stem pipe, described
Article to be measured is definite value with the distance of the egative film, the distance of the article to be measured and the exposure source.
Beneficial effect is：The utility model can be stable high into degree with fixed clamp small diameter tube, and has detection and localization
Function, the efficiency and exposure performance of exposure can be improved, so as to improve detection speed and efficiency.
