Abstract
The invention relates to a water seepage preventing assembly process of a rail vehicle sealing structure. The process comprises the following steps: a side wall plate and an outer edge groove of a chassis edge beam are in butt joint on a vehicle body assembly tire; the segment welding treatment is performed for an internal fillet welding line; the full welding treatment is performed for an external welding line; the seepage test is performed for the external welding line, that is, soapy water is coated in the external welding line, high-pressure wind is blown from the internal of a vehicle along the welding lines of the chassis edge beam and the side wall plate from inside to outside to check if surface air holes exist in external butt joint welding lines of the chassis edge beam and the side wall plate; if the air holes exist, the polishing repair welding is performed, and the seepage test is performed again; if the air holes still exist, the polishing repair welding is continuously performed until the seepage test is passed; the full welding treatment is performed for the internal fillet welding line; and a repair leveling procedure is performed. The process prevents the water seepage phenomenon of the chassis edge beam and the side wall plate sealing structure to provide powerful guarantee for quality of a later paint procedure, is easy to realize, and is excellent in quality control.
Description
Technical field
The present invention relates to a kind of rail vehicle hermetically-sealed construction water-impervious packaging technology, metal nondestructive inspection detection technique field.
Background technology
The hermetically-sealed construction that edge beam of chassis of rail vehicle and framed side wallboard form (as shown in Figure 1, after framed side wallboard 2 docks with the outside groove 3 of edge beam of underframe 1, inside and outside full weld, A is inner corners weld seam, B is outside weld seam) belong to one of primary load bearing structure of car body formation, the assemble method of this structure directly affects its sealing effectiveness and the assembling quality of later process.
Original packaging technology is after welding bodywork assembly tire completing the usual weld seam of these structure twice, directly enters leveling operation of returning something for repairs.There is following shortcoming in original packaging technology:
1, the complete manual welding of inside and outside twice elongated (about 20m) weld seam, especially outside weld seam is in horizontal position, and artificial long-time operation exists fatigue and causes producing the defect risks such as pore;
2, because framed side wallboard allows the amount of deflection that exists within 10mm, therefore the butt-joint clearance reality of the theoretical 2mm of the external connections of the outside groove of framed side wallboard and edge beam of underframe fluctuates between 2-12mm, causes welding quality destabilizing factor to strengthen;
3, there is the defect risks such as pore in outside weldquality, under not carrying out effective precautionary measures prerequisite, directly enter leveling operation of returning something for repairs (this operation need be watered in a large number), easily cause moisture to infiltrate in this structure, thus cause the quality accidents such as corrosion and rear road paint operation peeling come off.
Summary of the invention
Technical problem to be solved by this invention is, overcomes the above-mentioned shortcoming of prior art, provides a kind of rail vehicle hermetically-sealed construction water-impervious packaging technology, stops the generation of sealing structure infiltration phenomenon.
In order to solve above technical problem, rail vehicle hermetically-sealed construction water-impervious packaging technology provided by the invention, step is as follows:
Step 1, on bodywork assembly tire, framed side wallboard to be docked with the outside groove of edge beam of underframe;
Step 2, to the inner angle welding section of carrying out weldering process;
Step 3, full weld process is carried out to outside weld seam;
Step 4, seepage test is carried out to outside weld seam, namely suds are smeared in outside commissure, high-pressure blast is blown from inside to outside along the weld seam of edge beam of underframe and framed side wallboard in car, check whether edge beam of underframe and the outside butt weld of framed side wallboard have surface pores to exist, if there is pore, then carry out polishing repair welding, re-start seepage test, if still have pore, then continue polishing repair welding, until tested by seepage;
Step 5, full weld process is carried out to inner angle welding;
Step 6, enter leveling operation of returning something for repairs.
As preferred version of the present invention, the weld seam relating to body framing junction is full weld.
The present invention to the elongated weld seam of inside and outside twice make rational planning for technological process, weld step by step, the defect leakproof such as promoting the circulation of qi hole of going forward side by side test, thus ensure the sealing of this structure.
Present invention process has stopped the infiltration phenomenon of edge beam of underframe and framed side wallboard hermetically-sealed construction, thus provides strong guarantee for rear road paints process quality, and present invention process easily realizes, and quality control is good.

Detailed description of the invention
Embodiment of the present invention rail vehicle hermetically-sealed construction water-impervious packaging technology, step is as follows:
Step 1, on bodywork assembly tire, framed side wallboard to be docked with the outside groove of edge beam of underframe;
Step 2, to the inner angle welding section of carrying out weldering process, the weld seam of body framing junction is full weld, as the junction of side wall column end opening and edge beam of underframe;
Step 3, full weld process is carried out to outside weld seam;
Step 4, seepage test is carried out to outside weld seam, namely suds are smeared in outside commissure, high-pressure blast is blown from inside to outside along the weld seam of edge beam of underframe and framed side wallboard in car, check whether edge beam of underframe and the outside butt weld of framed side wallboard have surface pores to exist, if there is pore, then carry out polishing repair welding, re-start seepage test, if still have pore, then continue polishing repair welding, until tested by seepage;
Step 5, full weld process is carried out to inner angle welding;
Step 6, enter leveling operation of returning something for repairs.
In addition to the implementation, the present invention can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of application claims.
