A kind of weld jig of undercarriage V-arrangement linkage connector
Technical field
The application is related to the manufacture field of undercarriage, the specifically weld jig of undercarriage V-arrangement linkage connector
And application method.
Background technology
Solder technology has become one of leading technology method in the development and production of space shuttle.Its progress and hair
Exhibition can not only mitigate the weight of aircraft, but also for space shuttle structure design newly conceives offer technical support, promote aviation to fly
The raising of machine performance.
Undercarriage is to provide to be slided on the ground when taking off, landing and runs, slides what is parked.It is the main portion of aircraft
One of part, the quality and reliability of its service behaviour directly affect use and the safety of aircraft.Taken off to effectively complete
Landing function, undercarriage welding design is faced with many various requirements such as structure design, mechanism's design.
Present generation aircraft, in order to reduce aircraft drag, prevents high velocity air from destroying undercarriage due to the requirement to air speed,
Air maneuver agility is improved, undercarriage income must influence minimum sky after aircraft lift-off to housing construction and aircraft drag
Between in.Therefore the flexible jack of undercarriage is the important component of undercarriage, as shown in figure 1, the flexible receipts of undercarriage
Laying mechanism is made up of many for the V-arrangement connecting rod being driven, and the connecting rod includes joint and circular tube shaped connecting rod, to V-arrangement connecting rod
The welding of joint and connecting rod be problem in manufacturing, in traditional welding structure, after joint is connected with connecting rod, by water
Placing flat is welded, but so it cannot be guaranteed that the integrality of welding.The operating space at the joint back side is small simultaneously, visual
It is low, it is impossible to ensure the reliability of welding, it is therefore desirable to design a kind of new structure.
As shown in figure 1, V-arrangement connecting rod has treats welding line everywhere, front end bidirectional joint and two weld seams and two of connecting rod
Individual connecting rod tail end with the weld seam between an one-way joint, and bidirectional joint is must assure that in welding process and is unidirectionally connect
Location dimension between head, and the location dimension between two one-way joints, and to meet two one-way joints relative to
The angular bisector of bidirectional joint is symmetrical.If ensureing to weld the prologue and operability in space, must just make to treat welding line
Can be horizontally rotated around the axis of tubular link respectively, horizontality is in if necessary to one of connecting rod, just can only profit
Positioned with bidirectional joint and one-way joint, therefore how to be caused connecting rod horizontal positioned using the hole on the end connector of joint two,
And drive and treat that welding line rotates, the requirement of tack welding size is also met simultaneously, be the realistic problem that the application needs to solve.
