It is short, so as to play the role of adjusting car body size, control welding deformation.
Welded using a kind of welding tooling of overhead rail train body of the present embodiment, specific welding method include with
Lower step：
Step 1: carrying out laser before car body welding to welding tooling, integrally school is examined.12 groups of side bar clamping dresses are adjusted first
It puts 120 and is located at same level, technique is then carried out high-volume to tooling according to vehicle body bottom frame width, to offset welding of underframe horizontal stroke
To contraction distortion, to ensure tooling during adjusting about central symmetry, to ensure the symmetry of chassis group weldering.
Step 2: welding assembly is carried out to chassis.Referring to Fig. 6 to Fig. 8, welding tooling provided in this embodiment is to chassis
During 200 progress welding assembly, by arranging 12 groups of side bar clamping devices 120, edge beam of underframe front type block lower surface is placed
In U-shaped mounting base, edge beam of underframe is adjacent to edge beam of underframe front type block upper surface, and then chassis 200 is compressed with the second screw rod 7
Formation rigidly fixes, and measures the width between the symmetry and two side bars of two edge beam of underframe so that two edge beam of underframe it is symmetrical
It spends and is less than 3mm, after the width dimensions between two side bars meet drawing tolerance, lift the big bottom plate of chassis, the big bottom plate of chassis is made uniformly to take
It is connected on two edge beam of underframe, adjusts the big bottom plate of chassis later about central symmetry, lap weld is welded.Welding is completed
Flange is carried out to chassis afterwards, changes edge beam of underframe front type block into edge beam of underframe reverse side type block, is carried out by above-mentioned same method
The welding of chassis reverse side.Because of the U-type groove interface that the mounting base in side bar clamping device uses, front type block is replaced with reverse side type block
It is very convenient, it can realize the welding of chassis front and reverse side simultaneously by a basic tooling.
Step 3: welding assembly is carried out to head cover.Referring to Fig. 9 and Figure 10, welding tooling provided in this embodiment is to top
When lid 210 carries out welding assembly, head cover 210 is placed on crossbeam 110, is fastened head cover 210 by side bar clamping device 120
On crossbeam 110, edge beam of underframe type block is changed into tip cap edge beam type block, a quadrat method is welded according to chassis 200, to head cover
210 are welded.
Step 4: assembled welding is carried out to entire car body.Referring to Figure 11, entire car body, that is, chassis 200, head cover 210 and
In the assembled welding of side wall 220, chassis 200 is first hung in into tooling, chassis 200 is fixed and coordinated using side bar clamping device 120
Hoist tenses chassis 200, and chassis 200 is made to be adjacent to edge beam of underframe front type block 131.Because tooling pre-sets degree of disturbing,
Chassis 200 is formed naturally pre- disturb after tensing.Secondly lifting side wall Unit 220 makes side wall unit be adjacent to assembling with edge beam of underframe
Afterwards, section solid welding is carried out to determine.Then head cover 210 is lifted again, is treated that head cover 210 is fallen completely within and is bonded back segment solid welding with side wall unit and determines.
Then the first jury strut 310 is used to adjust the size between each doorframe, first by the first jury strut 310 and vehicle
Gate width direction is parallel, carries out elongating or shortening the first jury strut 310 by rotating the second nut and third screw rod
Length is bigger 2-3mm than the theoretical value of gate-width, and the cushion block at both ends is close to side wall door pillar, to offset side wall Unit 220 and bottom
The transverse weld of frame 200 and head cover 210 is shunk (referring to Figure 12).As shown in figure 13, each door is adjusted using the first jury strut 310
It is first that the first jury strut 310 is parallel with car door short transverse during size between height, pass through and rotate the second nut and third
Screw rod elongate or shorten the big 4-5mm of theoretical value for so that the length of the first jury strut 310 is higher than door, the cushion block point at both ends
It is not close to chassis and head cover, is shunk to offset side wall Unit 220 with the longitudinal measure of chassis 200 and head cover 210.Such as Figure 14
It is shown, when adjusting the symmetry of car body using the second jury strut 320,2 the second jury struts 320 are placed on car body first
Diagonal positions, by rotating third nut and the 4th screw rod Symmetry degree no more than 3mm, the pole at both ends respectively with
Edge beam of underframe and head cover side bar are close to, and to prevent the dislocation of head cover 210 and chassis 200, ensure the stability of body construction.
By the adjustment of the critical sizes such as door height, gate-width, car body diagonal it is qualified after, complete chassis and side wall door pillar weld seam and
The welding of head cover and side wall door pillar weld seam；The welding of framed side wallboard and chassis, framed side wallboard and head cover weld seam is completed after welding again；It
Carry out the assembling of car body other component and welding (such as end wall of car body and drivers' cab column) again afterwards.Intersection is generally followed in welding
Symmetrical welding principle, with less welding deformation, ensures car body overall dimensions.
Step 5: by after all weld seam welding of car body, car body is stood 4-5 hours, waits weld seams cooling and stress elimination
Afterwards, the first jury strut and the second jury strut are dismantled, then by car body tread flaking.
In conclusion welding tooling provided by the utility model is simple in structure, novel in design, easy to operate, versatile,
In addition welding deformation can also be effectively controlled, positioning and anti-welding deformation dual function is realized, both ensure that quality, reduce
Labor intensity also saves a large amount of assembling adjustment time, improves production efficiency.
The above descriptions are merely preferred embodiments of the present invention, is not intended to limit the utility model, for this
For the technical staff in field, various modifications and changes may be made to the present invention.It is all in the spirit and principles of the utility model
Within, any modification, equivalent replacement, improvement and so on should be included within the scope of protection of this utility model.
