Background technology
Undercarriage is aircraft taxi, landing, the parts of support aircraft entirety, and wherein undercarriage urceolus is major part, and it seals
Performance is closely related with the damping performance of aircraft shock mitigation system.And undercarriage urceolus is in use, owing to inside enters air
Or it is filled with compressed air, during takeoff and landing and the change of ambient temperature all can cause air heats, condensation to be formed
Water vapour, steam is met the cold formation globule and is condensed in undercarriage outer tube inner wall, forms local micro cell, thus can cause inwall office
Portion corrodes, and long-time use results even in undercarriage outer tube inner wall excessive erosion.Have a strong impact on the sealing property of undercarriage urceolus.
For recovering there occurs the undercarriage urceolus sealing property of corrosion, need to carry out plating and repair.And a height of 1m～2m of undercarriage urceolus,
The highest, the conventional groove electro-plating method that enters needs to immerse in tank liquor undercarriage urceolus entirety, need the degree of depth of coating bath be enough to by
Part submergence, and the electroplating bath liquid measure needed is big.For the reparation of undercarriage urceolus can be efficiently completed under limited conditions, can
With the outer tube inner chamber of undercarriage for tank liquor loop-body, to design and produce sealed circulation system to complete the plating of undercarriage outer tube inner wall
Repair.
Summary of the invention
It is an object of the invention to: a kind of bath solution circulating device being tank liquor loop-body with the outer tube inner chamber of undercarriage is provided, with
The undercarriage outer tube inner wall plating solved under limited conditions is repaired, and improves production efficiency, saves electroplating cost.
The technical scheme is that undercarriage outer tube inner wall electroplanting device, it includes: tank liquor entrance, lower seal blanking cover,
Upper sealing blanking cover, tank liquor exports, galvanic anode, water pump, tank, plastic tube；It includes: lower seal blanking cover, upper seal plug
Lid, galvanic anode, water pump and tank；
Upper sealing blanking cover designs and produces according to undercarriage outer tube structure, is assemblied in undercarriage urceolus upper end, is used for closing outside undercarriage
Cylinder upper port, prevents tank liquor from overflowing；Upper sealing blanking cover bias hole milling, discharges for tank liquor backflow and gas；Center hole milling, uses
In clamping, spacing galvanic anode upper end；
Lower seal blanking cover designs and produces according to undercarriage outer tube structure, is assemblied in undercarriage urceolus lower end, is used for sealing outside undercarriage
Cylinder lower port, prevents tank liquor from flowing out；Lower seal blanking cover upper surface center groove milling, is used for fixing, clamping galvanic anode lower end；Partially
Heart hole milling, is used for connecting plastic tube input bath solution；
Tank is used for containing bath solution；
Water pump and plastic tube are used for inputting and refluxing tank liquor；
Galvanic anode is arranged on undercarriage outer barrel, and its upper end is protruding by stating hole A on upper seal plug lid, its position, lower end
In the mounting groove of lower seal blanking cover.
Beneficial effect: the present invention solves undercarriage urceolus and electroplates reparation problem under limited conditions, and device assembling is simple, behaviour
Facilitate, improve plating and repair production efficiency；Electroplating bath liquid measure needed for device is little, be no longer necessary to electroplating bath, has saved life
Produce cost.
Promote the circulation of bath solution owing to being provided with water pump, the present invention also has tank liquor agitating function, it is to avoid bubble during plating
It is attached to electroplated component surface and causes coating that pin hole occurs.
