The specific embodiment:
For technological means, creation characteristic that the present invention is realized, reach purpose and effect and be easy to understand and understand, below in conjunction with concrete diagram, further set forth the present invention.
A kind of aircraft surfaces physics removes lacquer craftwork,
Physics paint removal process using operating pressure is at 200～220MPa, and flow is at the rotary-atomizing water jet of 30～50L/min; With uniform shower nozzle translational speed and constant best range; Attach aircraft skin surface mobile operating successively with the fixing rotary nozzle that cleans wide cut, promptly kept range, can form vacuum chamber again; In time reclaim sewage and coat of paint, operation field avoids producing water smoke simultaneously.
As shown in Figure 1, the six axial lengths robot 2 of cranking arm is arranged on the track 3 of aircraft 5, and six axial lengths are cranked arm and rotary nozzle 4 are installed in the robot 2, and rotary nozzle 4 connects super-pressure pump unit and vavuum pump units 1.
As shown in Figure 2; The step of physics operation is following: the normal pressure pure water forms the super-pressure water source from filtered water tank through fore pump, fine filter to super-pressure pump; If high-pressure water is then safety valve jumping up warning of superpressure; Nominal situation guarantees can get into 300mm major diameter rotary-atomizing shower nozzle or 150mm minor diameter rotary nozzle on request with the reversal valve of stable operating mode entering extreme pressure hose to robotic end-of-arm through air vent valve, so far forms the operation of super-pressure rotation pure water jet on the aircraft skin surface.Meanwhile, vavuum pump gets into foul water tank through the vacuum hose on two shower nozzles with sewage and coat of paint suction.
Like Fig. 3, shown in Figure 4; The rotatory sealing 41 that major diameter rotary nozzle and minor diameter rotary nozzle include spray boom 43, are installed in the nozzle 44 of spray boom lower end and are installed in spray boom 43 upper ends; Spray boom 43 places in the vacuum chamber 46 with nozzle 44; The hairbrush 45 that vacuum chamber 46 edge clampings are used to seal, vacuum chamber 46 connects vacuum hose 42, and spray boom 43 connects air motor 47 through transmission device.
Like Fig. 1, Fig. 3, shown in Figure 4; Major diameter rotary nozzle and minor diameter rotary nozzle are 90 ° of installations on six axial lengths are cranked arm the mechanical arm of robot 2; In order to guarantee constant best range, rotary nozzle 4 is forced adherent traversing by mechanical arm, and shower nozzle 44 drives and regulates with (300 ~ 400rpm) operations of an optimum speed by air motor 47; Water under high pressure forms rotating fluid through rotatory sealing 41, spray boom 43 to nozzle 44; Spray boom 43 places with nozzle 44 and forms jet flow field in the vacuum chamber 46,45 sealings of vacuum chamber 46 edge clamping hairbrush, and vacuum chamber 46 connects vacuum hose 42 to vavuum pump unit.The normal pressure clear water is through the super-pressure generating process; Supervene the high temperature flow field about 80 ℃, under the acting in conjunction in vacuum draw and high temperature flow field, after water jet hits paint removal; Sewage and coat of paint are drawn back foul water tank; Skin-surface then promptly removes promptly and does, and need not clean or dry, and the scene can not produce the water smoke that fills the air yet.
Like Fig. 5, shown in Figure 6, the artificial washer of carrying out comprises the rotary nozzle 4 that is installed on the washer framework 7, and washer framework 7 upper ends also are equipped with water under high pressure control valve 6, and hand operated pneumatic control valve 8 is installed on the handle of washer framework 7.
The artificial washer of carrying out is specifically designed to the occasion (like fighter plane) of aircraft upper surface.Fig. 5 is a 300mm major diameter plane cleaner, can solve most of upper surface covering paint removal problem.Fig. 6 is a 150mm perpendicular type curved surface washer, can solve the covering paint removal problem of surface blending circular arc.These two kinds of washers all are provided with hand operated pneumatic control valve 8 specially at the handle place and control the water under high pressure control valve, by the break-make of staff STOCHASTIC CONTROL high-pressure water jet.In like manner, these two kinds of washers do not produce the water smoke that fills the air because of vacuum chamber yet.Even (4m/min) that shower nozzle moves do not stop, and it is important not repeating not damaging skin-surface.
More than show and described basic principle of the present invention, principal character and advantage of the present invention.The technical staff of the industry should understand; The present invention is not restricted to the described embodiments; That describes in the foregoing description and the specification just explains principle of the present invention; Under the prerequisite that does not break away from spirit and scope of the invention, the present invention also has various changes and modifications, and these variations and improvement all fall in the scope of the invention that requires protection.The present invention requires protection domain to be defined by appending claims and equivalent thereof.
