3）Adjust all large tunnels axialities are installed and adjust the position that pointer is measured on auxiliary device so that all measurement pointers
Top keeps identical relative position with the kernel of section of section cylinder corresponding position；
4）Close up all sections, so that each top measuring pointer is located along the same line.
Step 3）Described in measure the position on pointer top to realize up and down by adjustable bolt and pulling and pushing of measurement pointer
Left-right and front-back is adjusted.
The invention has the beneficial effects as follows：This device will cause outside cylinder outside the internal not wind-tunnel inner barrel measurement point of intervisibility
Portion measures, and solves the problems, such as obstructed optionally lower axis, absolute altitude, the bad measurement of axiality.By bar hole, adjustable bolt
And the adjustment of scalable measurement pointer, precise positioning measurement point is it is ensured that tubular axis, absolute altitude, axiality accuracy.
