Position.
Before measurement, rotated around locating dowel by plate and make torsion spring store power, so make the fixing location-plate in locating dowel top with
On the left of plate, the lasso of upper end rotates against, on the left of location-plate and plate the location hole of upper end lasso to timing, by alignment pin
It is inserted simultaneously into the above-mentioned two positioning in the holes aligning, make the lasso circumference locking of upper end on the left of location-plate and plate；Adjust positioning
The circumferential position of cover for seat is inserted in post lower end, makes locating dowel connect plate and connects with a fin on stabilising arrangement empennage cylinder to be measured
Touch.
During measurement, by the free end of lower moulded rod, alignment pin is extracted from the two positioning in the holes aligning, location-plate with
On the left of plate, lasso lock-out state in upper end releases；In the presence of torsion spring, plate rotates around locating dowel, and then stirs to be measured stable
The empennage cylinder of device rotates around jet pipe, by observing rotating speed and the time that empennage cylinder rotates relative to jet pipe, draws this stabilising arrangement
Motility.By adjusting the empennage cylinder of stabilising arrangement and the assembly technology of jet pipe, so that the motility of stabilising arrangement is consistent, enter
And improve the concordance that stabilising arrangement is adjusted to rocket projectile flight path.
Beneficial effect
The structure of the detecting device of the present invention is simple, easy to operate, solves traditional handicraft and cannot measure rotatable stable dress
Put the technological difficulties of motility, and then ensure that the stabilising arrangement of projectile tail to the conforming requirement of regulation of rocket projectile flight path.
