Summary of the invention
The technical problem to be solved in the present invention is to provide the online boring method of a kind of auto body, large to solve car door and the side-wall outer-plate gap of prior art, needs loaded down with trivial details adjustment, therefore can increase car load productive costs, reduces the problem of car load exterior quality.
For solving the problems of the technologies described above, embodiments of the invention provide a kind of auto body online boring method, comprising:
Step 1 is processed mounting-positioning holes on fabricated section, stamps default hole on the vehicle body sheet metal corresponding with fabricated section;
Wherein, fabricated section in described step 1 is back door hinge adapter plate, described mounting-positioning holes is the installation via hole of being located on described back door hinge adapter plate, described vehicle body sheet metal comprises B column reinforcement plate outside plate, B column reinforcement plate inner panel and side-wall outer-plate, all processes knock hole and through hole is installed on described B column reinforcement plate outside plate, B column reinforcement plate inner panel and side-wall outer-plate.
Wherein, described step 2 comprises described back door hinge adapter plate is welded between B column reinforcement plate outside plate and B column reinforcement plate inner panel, described side-wall outer-plate is welded in to B column reinforcement plate outside plate lateral surface, and makes described installation via hole corresponding with the position of positioning hole on described vehicle body sheet metal.
Wherein, described step 3 is included on described back door hinge adapter plate, with installation lead to the hole site corresponding section processing one, tapped bore is installed.
Wherein, the boring method of described installation tapped bore selects drill tap to process or Selection and Constitute cutter is processed, first tapping after boring.
Wherein, process described installation tapped bore and select the outline line of gusset car door cooperation to position, or select the car door mounting-positioning holes on gusset lower-edge beam.
Wherein, process and install after tapped bore, on B column reinforcement plate inner panel, weld B post inner panel.
The beneficial effect of technique scheme of the present invention is as follows:
In such scheme, realized the conformability of position relationship between body hinge attachment point and the external appearance characteristic line of side-wall outer-plate, ensured car door and gusset outward appearance gap evenly; On the uniform basis of car door and side-wall outer-plate gap, can further dwindle gap width, improve vehicle appearance quality; Loaded down with trivial details adjustment work when eliminating or having reduced car door assembling, boosts productivity, and reduces costs.
