Description
Technical field
The present invention relates to a kind of uplock gap detection device and the methods of detection assembly, belong to air equipment field.
Background technology
The main landing gear of aircraft uplock Mr. Yu's aircraft, when main landing gear is packed up, uplock is in locked state, will
Main landing gear is fixed on stowed position, and main landing gear unlocks uplock before putting down, and realizes smoothly putting down for undercarriage, is to rise and fall
An important component in frame system.
Uplock part is more, structure is more complicated, and air-tightness requires high and pressure higher, it is desirable that detects between guarantee
Gap, size are more.Uplock includes 2 kinds of specifications of left and right part.Uplock by lock housing, piston rod, latch hook, locking key, spring, mandril,
Rocking arm, ring, ozzle and other parts are constituted.Uplock requires the main gap of detection, size to have：Simulate locked state, inspection
It looks into locking key and is bonded rate 70% or more with the contact area of latch hook；Locked state is simulated, adjustment mandril ensures between mandril and locking key
Gap tightens nut after being 0.5-1mm；Locked state is simulated, checks latch hook higher than two 0.7-1.2mm of plane in lock housing；Latch hook
When concordant with lock housing, latch hook and locking key are checked（Two surfaces of former fitting rate 70%）Between the gap that generates should be 1.5-3mm.
These gaps, size are not only not easy detection and ensure, but also also interrelated between different sizes.If structure of the detecting device is unreasonable
Or uplock detects, assembly method is unreasonable, not only efficiency is low but also is not easy 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 that a set of and it is completely right
The tooling of title in the locking of connection oil circuit state Imitating undercarriage, unlocking condition and can not carry out gap detection and ruler
Very little guarantee cannot function as experimental rig use, need between experiment and assembly process back and forth repeatedly, and detection efficiency is low,
And detection result is difficult to ensure.
Invention content
The present invention is intended to provide a kind of uplock gap detection device and the method for detection assembly, which can
Also ensured while ensureing product quality by reasonable arrangement process for the multiple gap detections of uplock and Assurance of Size
