Abstract
The utility model discloses an emergent testing tool of putting undercarriage. Including pulley, auricle, casing, support arm, sleeve, lead screw, cable wire, pulley and auricle one end pass through bolt or pin joint, the pulley is around the bolt or the free rotation of pinning, the auricle other end and lead screw rigid coupling, casing include the ring flange, the sleeve have the internal thread and with the lead screw cooperation, support arm one end and ring flange rigid coupling, the other end and sleeve rigid coupling, the cable wire is walked around the pulley, and cable wire one end rigid coupling the drag hook, the one end rigid coupling pull ring, the drag hook can put the undercarriage and be connected with emergent. Of the present invention has solved certain medium -sized intermediate range cargo airplane of china, can't measure the emergent problem that nose -gear system design index required of putting since production, manufacturing always. The technology and equipment design talent has been trained to the technological difficulties problem in certain medium -sized intermediate range cargo airplane test system of puzzlement china that has broken through.
Description
Technical field
The present invention relates to a kind of the emergent of China's medium-sized intermediate range shipping platform that be specifically designed to and put nose-gear system testing frock, be mainly used in testing emergent force value of putting nose-gear system and whether meet design objective requirement.
Background technology
Landing-gear emergency extension is that aircraft is in the lower a kind of system realizing drop that is in an emergency, can this this system works reliably working, directly jeopardize the life of aviator and threaten transport goods and materials to send to destination safely on time, also affecting the safety of aircraft carrier aircraft platform simultaneously.
In order to avoid aircraft occurs meeting an urgent need putting the situation of nose-gear, this medium-sized medium range transporter designer has made strict test request, to stop fatal crass.But the emergent of the said firm puts nose-gear system for many years, due to the restriction of construction space restriction and process, Fixture Design thinking, the emergent nose-gear system of putting of this medium-sized medium range transporter is caused not tested according to design objective requirement.
In design and researchp process, for designing a kind of practicality and easy frock, go deep into production line and have collected up to a hundred of Various types of data parameter, the folding and unfolding principle, jack drawing etc. of undercarriage are analyzed simultaneously, grasp the theory of related fields and the knowledge of practical application aspect, Prometheanly propose this process.
Summary of the invention
Goal of the invention:
The present invention, while guarantee testing crew safety, overcomes construction access obturation, provides a kind of proving installation that can use under the inaccessible environment of this medium-sized medium range transporter.
Technical scheme:
Technical scheme of the present invention: a kind of testing tool of landing-gear emergency extension, it comprises pulley 1, auricle 2, housing 3, support arm 4, sleeve 5, screw mandrel 6, cable wire 7; Described pulley 1 is connected by bolt or pin with auricle 2 one end, pulley rotates freely around bolt or pin, auricle 3 other end and leading screw affixed, housing 3 comprises ring flange, and sleeve 5 has internal thread and coordinates with screw mandrel 6, support arm 4 one end and ring flange affixed, the other end and sleeve 5 affixed, cable wire 7 walks around described pulley 1, and the affixed drag hook in cable wire 7 one end, one end is affixed draw ring, described drag hook can be connected with landing-gear emergency extension.
Beneficial effect
The invention provides a kind of aircraft to meet an urgent need and put the Fixture Design technology of nose-gear, breach certain medium-sized medium range transporter to produce in decades, cannot meet an urgent need and put the scheme of nose-gear design objective by Accurate Determining, solve the bottleneck problem always perplexed in certain medium-sized medium range transporter measuring technology.Meanwhile, this frock energy specific aim solves individual difference problem in China's medium-sized medium range transporter nose-gear emergency system, provides a kind of versatility, practicality, simple, novel frock test technique.
Meanwhile, in present invention process Fixture Design tackling key problem process, the technician of Main Tissues youth, is designed to China by this and has cultivated some outstanding technology and pattern assembly designing talents.For technician has been laid in certain medium-sized medium range transporter technology and pattern assembly design from now on of China.

Wherein: 1-pulley, 2-auricle, 3-housing, 4-support arm, 5-guide rod, 6-screw mandrel, 7-cable wire.
Embodiment
A testing tool for landing-gear emergency extension, it comprises pulley 1, auricle 2, housing 3, support arm 4, sleeve 5, screw mandrel 6, cable wire 7; Described pulley 1 is connected by bolt or pin with auricle 2 one end, pulley rotates freely around bolt or pin, auricle 3 other end and leading screw affixed, housing 3 comprises ring flange, and sleeve 5 has internal thread and coordinates with screw mandrel 6, support arm 4 one end and ring flange affixed, the other end and sleeve 5 affixed, cable wire 7 walks around described pulley 1, and the affixed drag hook in cable wire 7 one end, one end is affixed draw ring, described drag hook can be connected with landing-gear emergency extension.
Its practical approach is: the first step, housing 3 is positioned over aircraft and meets an urgent need and put the exclusive architecture tapping of nose-gear.
Second step, puts nose-gear test macro by cable wire drag hook is connected with emergent, ensures that drag hook is drawn cable wire and meets an urgent need that to put nose-gear test macro in alignment.If when not forming straight line, adjusting screw or housing ensure straight line.
3rd step, operating personnel stand on the ring flange of housing, are connected by the test macro of landing-gear emergency extension with cable wire draw ring one end.
4th step, reads measurement data from test macro, and determines whether to meet design objective requirement.
