The utility model discloses a simple process, the still originality that reassembles after the dismantlement is good, and the cost is lower.
Description
Technical field
The utility model belongs to automobile body components, is specifically related to a kind of front-end module.
Background technology
Front-end module is positioned at automotive front end, installs the impact to front shroud lock time load impacting when the various motion operating mode of automobile of fixing and carrying radiator and front shroud are closed for radiator, head light, front bumper, front shroud lock etc.The front-end module of current routine mainly contains panel beating welding and plastics general assembly two kinds of front-end module schemes.
As shown in Figure 5, existing panel beating welding front-end module comprises left column 3, right column 1, front lower member 2 and front upper member 4, during assembling, first left column 3 is welded on left cabin side bar assembly 5, right column 1 is welded on right cabin side bar assembly 7, wherein, right cabin side bar assembly 7 and left cabin side bar assembly 5 are welded in front panel 6; Then at front housing assembly station, the two ends, left and right of front lower member 2 are welded with the lower end of left column 3 and the lower end of right column 1 respectively, the mounting hole 4a plain bolt at the two ends, left and right of front upper member 4, nut are connected with the upper end of left column 3 and the upper end of right column 1.Left column 3, right column 1, front lower member 2 and front upper member 4 is made to form " mouth " glyph framework of installing for radiator.Easy to assembly in order to radiator, so generally front upper member 4 is designed to total piece installing, first assemble in welding shop tool locating, arrive assembly shop dismounting again, but in unloading process, because vehicle body sprays paint through coating baking, there is welding stress release, left column 3 and right column 1 can depart from the position before the front upper member 4 of dismounting.Before ressembling during upper member 4, because plain bolt is without positioning function, or positioning precision is bad, during assembling, is difficult to the precision of each attachment point on upper member 4 before ensureing, thus affects the coupling of front bumper, head light.Therefore the difficult point controlled time outward appearance adjustment is all often and produces.
In addition, plastics front-end module is that left column, right column, front lower member, front upper member are integrated into a plastic monoblock, and precision is higher, lightweight.But because Plastic Parts intensity is not as sheet metal component, often need to embed panel beating between local in plastic skeleton, such plastics front-end module not only in loss of weight advantage not obvious, and cost comparatively panel beating scheme is high.
Therefore, be necessary to develop a kind of new front-end module.
Summary of the invention
The purpose of this utility model is to provide a kind of front-end module, and its technique is simple, and that ressembles after dismounting is Well-recovered, and cost is lower.
Front-end module described in the utility model, it is overall in " mouth " font, comprise left column, right column, front lower member and front upper member, the two ends, left and right of front lower member are welded with the lower end of left column and the lower end of right column respectively, the two ends, left and right of front upper member are respectively equipped with mounting hole, be respectively equipped with project-welding nut in the upper end of left column and the upper end of right column, the two ends, left and right of described front upper member by mounting hole, project-welding nut with self-align bolt respectively with the upper end of left column and the upper end of right column is corresponding connects;
Described self-align bolt comprises nut and screw rod, and is arranged on the guide part between nut and screw rod, and the diameter of this guide part is consistent with the diameter of mounting hole.
Described left column, right column, front lower member and front upper member are sheet metal component.
During assembling, first left column, right column, front lower Member Welding are become a U-shaped framework, being located through by welding jig adopts self-align bolt front upper member to be assembled to front-end module U-shaped framework being formed " mouth " font again, is finally integrally welded to by the front-end module of " mouth " font on right cabin side bar assembly and left cabin side bar assembly.
The beneficial effects of the utility model:
(1) because front upper member is connected with adopting self-align bolt between left column and right column, because self-align bolt has self-locating function, even if distortion after there is welding stress release after dismounting, left column and right column also can be returned to initial makeup location when again assembling by self-align bolt, thus ensure that the accuracy resumption of each attachment point on front upper member is to higher level, and carry out auxiliary positioning without the need to any positioning tool, improve efficiency of assembling;
(2) front-end module is integrally welded on the side bar of cabin, left and right, is welded on the side bar of cabin, left and right relative to each component, the precision of front-end module relative to car load can be improved, be convenient to the clearance surface difference controlling whole front end area.
In sum, structure of the present utility model is simple, applicability is high, by the self-align principle of creationary employing bolt and reasonable distribution assembling level, because welding stress discharges the reducibility difference problem caused after effectively improving front upper component removal, and under ensureing panel beating scheme strength conditions, cost is better than plastics front-end module.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As the front-end module that Fig. 1 shows, it is overall in " mouth " font, and comprise left column 3, right column 1, front lower member 2 and front upper member 4, described left column 3, right column 1, front lower member 2 and front upper member 4 are sheet metal component.The two ends, left and right of front lower member 2 are welded with the lower end of left column 3 and the lower end of right column 1 respectively, the two ends, left and right of front upper member 4 are respectively equipped with mounting hole 4a, project-welding nut 10 is respectively equipped with in the upper end of the upper end of left column 3 and right column 1, the left end of described front upper member 4 is connected with the upper end of left column 3 by mounting hole 4a, the self-align bolt 9 of project-welding nut 10, and the right-hand member of front upper member 4 is connected with the upper end of right column 1 by mounting hole 4a, the self-align bolt 9 of project-welding nut 10.Described self-align bolt 9 comprises nut 9b and screw rod 9c, and is arranged on the guide part 9a between nut 9b and screw rod 9c, and the diameter of this guide part 9a is consistent with the diameter of mounting hole 4a.
As Fig. 1 to 4 shows, during assembling, first the lower end of the lower end of left column 3 and right column 1 is welded with front lower member about 2 two ends respectively, form a U-shaped framework, then be located through self-align bolt 9 by welding jig and front upper member 4 be assembled to the front-end module 8 U-shaped framework being formed " mouth " font.Finally be integrally welded to by the front-end module 8 of " mouth " font on right cabin side bar assembly 7 and left cabin side bar assembly 5, right cabin side bar assembly 7 and left cabin side bar assembly 5 are welded in front panel 6.Because the front-end module 8 of this " mouth " font is by once welding and assembly process, therefore overall precision is high.When after upper member 4 before assembly shop dismounting, left column 3 and right column 1 move because Y-direction occurs in welding stress releasing position, before again assembling after having assembled radiator during upper member 4, left column 3 and right column 1 can be made to return to initial makeup location by the positioning action of self-align bolt 9, thus ensure that the accuracy resumption of each attachment point on front upper member 4 is to higher level.
