Start right baffle-plate displacement control system 10 and right shell body displacement control system 8, making right baffle-plate 2 and right shell body 5, it is returned
To original position；
Start worktable displacement control system 9, the workbench 4 of carrying honeycomb core is declined along Z-direction, shift length according to
Weld width and the honeycomb core born of the same parents length of side determine.Secondly, workbench 4 is made to be moved along Y-direction, because honeycomb hole is just in the present embodiment
Hexagon, so displacement of the workbench 4 along Y-direction is 1.5 times of honeycomb core born of the same parents' length of sides.
Repeat step 2- steps 5, successively weld out the honeycomb core of determination size.Now lower floor's cog belt in step 2 is
Upper strata cog belt in step 4.
In step 1, first place a cog belt and fixed on the table with fixture, as lower floor's cog belt；In lower floor's tooth
A cog belt is placed on shape band again, as upper strata cog belt.Upper strata cog belt and lower floor's cog belt it is symmetrical above and below place so as to
Form honeycomb hole.
This welding process is fixed by lower floor's cog belt, preseting solder, placement upper strata cog belt, solder side are heated, applied
Satisfactory honeycomb core is completed in ul-trasonic irradiation etc., welding.Tooth form strip is placed on accurate controlled level position and vertical position
The workbench put, workbench move down a normal pitch by displacement control system and move horizontally a pitch, hunting frequency
Linked with welding rhythm, realize automatic welding；Heating rod returns to heating location, places new solder and cog belt, enters
Enter next layer of welding assembly, realize the welding of multi-layer honeycomb core.Solder be specially design, by melting, forge, be rolled into paper tinsel
Band or thread or paste, are preset at honeycomb wicking surface to be welded, specific size and quality are related to honeycomb born of the same parents' size, then accurate cloth
It is placed on the ad-hoc location for the above-mentioned sawtooth strip for reaching temperature by heating, temperature.Solder density is small, and solder fusing point is low,
Strength of joint is high, good corrosion resistance.Welding process is carried out under ultrasonic assistant effect, makes tool heads by displacement control system
Surface is contacted with the institute face of weld, applies ul-trasonic irradiation, realizes that ultrasonic assistant welds.Substituted by welding connection cementing
Connection, it is greatly improved the intensity, corrosion resistance and weatherability of honeycomb core.
Heating system is mode of heating in electrothermal in the inventive method, while can also pass through other mode of heatings such as electromagnetism
Sensing heating is realized.Welding system is ultrasonic assistant welding system under atmospheric environment, while can also use brazing flux or protect
The inferior realization welding of atmosphere.
Certainly, the present invention can also have other various embodiments, ripe in the case of without departing substantially from spirit of the invention and its essence
Various corresponding changes and deformation, but these corresponding changes and deformation can be made according to the present invention by knowing those skilled in the art
The protection domain of appended claims of the invention should all be belonged to.
