Enclose equal locating and machining hole and installation through hole on outside plate.
Wherein, described step 2 includes described back door hinge installing plate is welded in B column reinforcement plate outside plate and B
Between column reinforcement plate inner panel, described side-wall outer-plate is welded in B column reinforcement plate outside plate lateral surface, and makes institute
State installation via corresponding with the position of positioning hole on described vehicle body sheet metal.
Wherein, described step 3 is included on described back door hinge installing plate and installs lead to the hole site corresponding section
Processing one installation screwed hole.
Wherein, the boring method of described installation screwed hole selects drill tap be processed or select
Gang tool is processed, first tapping after boring.
Wherein, process described installation screwed hole and select the contour line of gusset car door cooperation to position, or select
Car door mounting-positioning holes on gusset lower-edge beam.
Wherein, after processing installation screwed hole, B column reinforcement plate inner panel welds B post inner panel.
Having the beneficial effect that of the technique scheme of the present invention:
In such scheme, it is achieved that between the external appearance characteristic line of body hinge mount point and side-wall outer-plate, position is closed
The concordance of system, it is ensured that car door is uniform with the outward appearance gap of gusset；Equal with side-wall outer-plate gap at car door
On the basis of even, gap width can be reduced further, improve vehicle appearance quality；Eliminate or reduce car door
Loaded down with trivial details adjustment work during assembling, improves productivity ratio, reduces cost.
