Description
Technical field
The present invention relates to a kind of main assembling and welding process of automobile cab body, the both sides of especially heavily blocking the body assembly of operator's compartment do not have the heavily card driving body main assembling and welding process of roof drip.
Background technology
General, it is as follows heavily to block body shell cab body main assembling and welding process (branch units at different levels have been welded and have finished):
Dress welds engine casing assembly and left and right sides floor assembly--------will before enclose inner panel assembly engine casing assembly and left and right sides floor assembly and adorn the formation operator's compartment bottom assembly that is welded into one----dress welds left and right sides side wall assembly--the dress postwelding encloses assembly---and adorn and weld top cover assembly and air regulator upper skeleton assembly-commentaries on classics repair siding.The shortcoming of this technology is, preceding enclosing between inner panel and the car bonnet adopts the spot welding mode to be connected, and is rigidly connected, and in the vehicle ' process, because the effect of various load has caused car bonnet and before enclosed tearing of inner panel, causes the user to claim damages; In addition, refill top cover after back wall assembles again in the existing processes, at the position that top cover connects with gusset, especially in the rear portion of operator's compartment welding difficulty, welding gun must enter very trouble from car door, influences production efficiency, and is especially even more serious for the main welding wiring of automation.
Summary of the invention
Purpose of the present invention is exactly heavily to block the rear portion welding difficulty that body shell cab body master butt welding process causes operator's compartment at present in order to solve, influence capacity rating, problem such as fragile, provide a kind of have easy to operate, welding quality is good, and the both sides of advantage such as can effectively enhance productivity do not have the heavily card of roof drip and drive the body main assembling and welding process.
For achieving the above object, the present invention adopts following technical scheme:
A kind of both sides do not have the heavily card of roof drip and drive the body main assembling and welding process, and its step is,
1) dress weldering engine casing assembly and left and right sides floor assembly;
2) will before enclose inner panel assembly engine casing assembly and left and right sides floor assembly and adorn the formation operator's compartment bottom assembly that is welded into one, only the junction of preceding enclosing inner panel and floor, the left and right sides be welded;
3) dress weldering left and right sides side wall assembly;
4) dress weldering top cover assembly and air regulator upper skeleton assembly;
5) the dress postwelding encloses assembly;
6) riveted joint car bonnet with the junction of preceding enclosing inner panel;
7) change repair siding.
In the described step 1), car bonnet and floor, the left and right sides link together by spot welded mode in the side, spot pitch 25-40mm.
Described step 2) in, the spot welding mode is adopted in welding, and spot pitch is 25-35mm.
In the described step 3), during the side wall assembly of the dress weldering left and right sides, be connected by spot welded mode between left and right sides gusset and the floor, the left and right sides, spot pitch is 25-40mm; Left and right sides gusset is connected by spot welding with before enclosing between the inner panel, and the MIG weldering is carried out at the position that can't weld individually.
In the described step 4), when dress weldering top cover assembly and air regulator upper skeleton assembly, be connected by spot welding between top cover and the gusset, weld spacing is 25-40mm, and spot welded mode is connected between air regulator upper skeleton and the gusset, and weld spacing is 25-30mm.
In the described step 5), the dress postwelding is when enclosing assembly, between back wall and the top cover, between back wall and the gusset, between back wall and the car bonnet, all adopts spot welding to be connected between back wall and the floor, and the spot welding spacing is between the 25-40mm.
7, the both sides according to claim 1 heavily card that do not have a roof drip is driven the body main assembling and welding process, it is characterized in that: in the described step 6), the riveted joint process is a car bonnet and being connected of before enclosing adopted the form of riveting, and the riveted joint spacing is 38mm.
The present invention has changed existing welding sequence, in the end assembles back wall, the difficult phenomenon of subregion welding of having avoided first dress back wall to cause.Simultaneously car bonnet is connected with before enclosing by riveted way, makes to connect to be in a kind of flexible state, under the effect of various load, be unlikely to produce and tear.
The invention has the beneficial effects as follows: technology is simple, and is easy to operate, production efficiency height, good product quality.
