Description
Technical field
The present invention relates to a kind of method of uplock gap detection device and detection assembling, belong to air equipment field.
Background technology
Aircraft uplock is used for the main landing gear of certain aircraft, and when main landing gear is packed up, uplock is in locking state, will
Main landing gear is fixed on stowed position, and uplock is unlocked before putting down by main landing gear, realizes smoothly putting down of undercarriage, is to rise and fall
One of frame system vitals.
Uplock part is many, structure is more complicated, air-tightness have high demands and pressure higher it is desirable to detection ensure between
Gap, size are more.Uplock includes left and right 2 kinds of specifications of part.Uplock by lock housing, piston rod, latch hook, locking key, spring, push rod,
Rocking arm, ring, ozzle and other part are constituted.Uplock requires the main gap of detection, size to have: simulation locking state, inspection
Look into locking key and fit rate more than 70% with the contact area of latch hook;Simulation locking state, adjustment push rod ensures between push rod and locking key
Gap tightens nut for after 0.5 1mm;Simulation locking state, checks that latch hook is higher than two plane 0.7 1.2mm in lock housing;Latch hook
When concordant with lock housing, check that the gap producing between latch hook and locking key (two surfaces of former rate 70% of fitting) should be 1.5 3mm.
These gaps, size are not only difficult detection and ensure, and also interrelated between different size.If structure of the detecting device is unreasonable
Or uplock detection, assembly method are unreasonable, not only efficiency is low but also be difficult to ensure that quality even causes important parts to scrap.
The uplock detecting tool that tradition uses can only detect uplock left member, and the detection of right member has a set of and it is completely right
The frock claiming is it is impossible to connecting the locking of oil circuit state Imitating undercarriage, unlocking condition and carrying out gap detection and chi
Very little guarantee, it is impossible to use as assay device, needs multiple back and forth between test and assembly process, detection efficiency is low,
And Detection results are difficult to ensure that.
Content of the invention
