The 1, first framework module 16 of mouth composition, the second framework module 17, third framework module 4 and the 4th framework module 5, and it is respective respectively
It is completed, each process component and wallboard, attachment is finally assembled into headwall synthesis procedure.
(1) outlet parietal bone frame tooling is designed, tooling can be compatible with two kinds of end parietal bone frame productions (height top and flat-top)；First holding
Assembly side top bow 31, end head piece 32 and end top column 33, ensure end head piece 32 and other termination parietal bone in parietal bone frame tooling
There are 2.5mm differences in height, i.e., the plate thickness of one end top plate 34 for the material of frame tooling；In end head piece 32 and end 31 interface of top bow
Place increases anti-deformation to 3.5mm, and pressing device compression end parietal bone frame tooling is used in combination；The reverse side of first welding ends parietal bone frame tooling welds
Seam, then go out tire and turn-over, organize the fillet in normal shear of welding end parietal bone frame tooling；Assembly side top plate 34 ensures the indentation, there of end top plate 34
It is exactly matched with end head piece 32；Hold top plate 34 to hold head piece 32 for line of demarcation, upper weld whole full weld, lower part weld seam is only
Solid point；Opposite end top plate 34 carries out adjusting, ensures planarity requirements.
(2) headwall upper layer skeleton is extracted, is divided into the first framework module 16 and the second framework module 17, makes two kinds of skeletons
Module is symmetrical, and framework types are " rich " word class formation；According to two kinds of modular structures on carbon steel platform, compatibility is designed
Tooling；Group two kinds of module frameworks of weldering, postwelding carry out flatness adjusting to the built-in face of skeleton.
(3) floor and rectangular square tube of headwall lower layer skeleton and two layers of skeleton connection are extracted, is divided into third skeleton pattern
Block 4 and the 4th framework module 5, third framework module 4 and the 4th framework module 5 are the similar symmetrical module of structure, remove supporting beam
Position is different, remaining is symmetrical member；According to its double-layer structure, setting for a set of tooling is completed using the different locating piece of height
Meter, and meet the compatibility of two kinds of modules；After assembling framework module in tooling, compresses skeleton wallboard using pressing device and contact
Face reuses F folder clamp rectangulars square tube 41 and high locating piece；Group two kinds of module frameworks of weldering, postwelding to skeleton wallboard contact surface and
Side wall wallboard contact surface carries out flatness adjusting, and adjusting is also needed to ensure verticality≤1mm of two kinds of wallboard contact surfaces.
(4) end door frame 12, tie-beam 11, cab apron 13 are extracted, partition cart end door mouth composition；End door mouth tooling is designed,
It can be compatible with the topology requirement of a variety of end door mouths, vehicle is saved and replace the tooling adjustment time brought；It is assembled in tooling each
Component increases anti-deformation on the basis of clear door opening upper dimension bound；The weld seam of first welding ends doorframe 12 and cab apron 13, then weld
Connect all weld seams in doorway top；Postwelding adjusting gate size and windscreen mounting surface flatness.
Step B requires design headwall group mounted welder according to headwall size, changes by adjusting cab apron locating piece in tooling
Become tool structure, the headwall group to be compatible with a variety of models welds demand.
Step C, end door mouth composition 1 are placed in headwall group mounted welder down with windscreen installation.In headwall group mounted welder
Upper elder generation's assembly side doorway composition 1 ensures that the center line of headwall group mounted welder is overlapped with the center line of end door mouth composition 1, and assembly is public
Difference is between ± 0.5mm；Cab apron 13 and end door frame 12 are compressed using pressing device, ensures that locating piece patch is tight, reassembles two pieces of ends
Wallboard 2, adjustment end wall panel are ensureing wallboard dress just, and end wall panel 2 will form on 1 overlap joint with end door mouth, and 2 lower part of end wall panel is wanted and end door
The cab apron 13 of mouth composition 1 pastes sternly, and adjustment end wall panel 2 is ensureing dress just；End wall panel 2 and end door mouth are formed into 1 solid point；Reassemble end top
Composition 3 ensures that end top 3 center lines of composition form 1 center line with end door mouth and overlap, ensures that end top plate 34 and end wall panel 2 paste sternly, protect
Demonstrate,prove 3 installation of end top composition just, adjustment headwall is total high (being adjusted by raising or reducing end top composition 3), rearmost point fixed end
Top plate 34 and end wall panel 2.Pay attention to：All weld seams being related in this step, its welding deformation amount, only allows solid point in order to control.
Step D, successively erection welding third framework module 4, the 4th framework module 5, headwall stepped plate 6, step stiffening plate
7, end angle support 8, long babinet composition 9 and short babinet composition 10.
Third framework module 4 and the 4th framework module 5 are assembled, adjusts headwall beam overall and headwall skeleton diagonal line (by the
Three framework modules 4 and the 4th framework module 5 are adjusted towards extending out or receiving inwardly), anti-deformation 4mm is applied to headwall beam overall
Left and right clamps third framework module 4, the 4th framework module 5 and locating piece, compression end top composition 3 and headwall using pressing device
Group mounted welder patch is tight, all weld seams in welding step C；Assembly side wall stepped plate 6, step stiffening plate 7, end angle support 8, are first protected
The upper surface of the upper surface and end angle support 8 of demonstrate,proving all step stiffening plates 7 in the same plane, then carries out its two-sided welding；Dress
With long babinet composition 9 and short babinet composition 10, the weld seam of long babinet composition 9, short babinet composition 10 and headwall skeleton tooling is welded.
Pay attention to：Long babinet composition 9 and short babinet composition 10 include upper cover, bottom plate and box body wall, to prevent box body welding deformation from influencing
Follow-up assembly, all weld seams of box house only allow solid point.
Step E, successively erection welding wire-passing tube form the 15, first framework module 16 and the second framework module 17.Assembly weldering
Spool composition 15 is taken over, wire-passing tube composition 15 must could be assembled in babinet group postwelding；Assemble 16 He of the first framework module
Second framework module 17；The rectangle in the rectangular square tube 41 and the 4th framework module 5 on third framework module 4 is clamped using F
Square tube 41 prevents welding deformation from influencing skeleton verticality；Weld all welderings of the first framework module 16 and the second framework module 17
Seam, assembly group weld all headwall attachmentes 14.Pay attention to：All pressing devices and F folders be not when welding all weld seams of this step, in tooling
Energy loose unloading, prevents headwall welding deformation.
Headwall group welder is taken on tire and turn-over, it is all to weld front by step F after above-mentioned weld seam is adequately cooled
Weld seam, welding requirements ensure welded seal；Erection welding plane of structure plate 18 finally carries out adjusting to the headwall that group is soldered, protects
It demonstrate,proves its flatness and reaches quality requirement.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
With within principle, any modification, equivalent replacement, improvement and so on should all be included in the protection scope of the present invention god.
