Abstract
A kind of novel electric vehicle automobile body welding method belongs to electric vehicle production technology field.Including always spelling tooling and workbench, total spelling tooling is set on workbench, it is characterised in that：Side-wall inner-plate assembly, roof bow and floor pan assembly are first welded as body frame in always spelling tooling when carrying out total welding and connecing, then tooling opening will always be spelled, making vehicle body is fixed in left and right side-wall outer-plate assembly and body frame, vehicle body is fixed with head cover outside plate as packet body assembly, then packet body assembly and car door assembly, front anti-collision beam installation assembly, the secondary total spelling of subframe installation assembly progress.It is finished by the way that floor pan assembly and vehicle body are shifted to an earlier date assembly, then is always spelled, improve welding efficiency.Simultaneously as needed, can floor pan assembly and vehicle body be subjected to different collocation, in order to realize that doubling produces various types of electric vehicles.
Description
Technical field
The invention belongs to electric vehicle production technology field, specifically a kind of novel electric vehicle automobile body welding method.
Background technology
Currently, electric vehicle start it is like a raging fire at home grow up, the purposes of electric vehicle also the more is opened the more various
Change, thus the vehicle of electric vehicle is also varied, and then the pattern of its vehicle body is also far more than general-utility car vehicle body, and electronic
The automobile body welding efficiency of automobile is low, far can not meet needs of the market to electric vehicle.The vehicle body of electric vehicle is equally by six
Block car body panel is welded to each other, and includes the gusset plate with vehicle window mouth of the left and right sides, the front and rear panels of front and rear sides and
The top plate at top, the bottom plate of bottom.Usually artificial welding successively, welding efficiency is low, and positions and weld inconvenience, causes to weld
It connects of poor quality.A kind of welding method for the vehicle body being appropriate to electric vehicle thus is needed, to improve welding treatment and welding efficiency.
Chinese patent application CN201510436722.6 discloses a kind of electric car body welding method, and feature exists
In：Electric car body, the electric car body Welder are welded including using a kind of electric car body welding tooling
Dress includes the workbench with stabilizer blade, and left and right twice cross rail is symmetrically arranged on the workbench and forward and backward twice are vertical
Guide rail, the cross rail are equipped with locating rack, and the locating rack includes two horizontal cross bars with sliding slot, the cross bar from
The close one end in the workbench center is vertically arranged with a montant, and the montant top is equipped with horizontal location bar, at two
The upper end of the montant is connected with a vertical pole, and the locating rack is equipped with multiple align clamps；It is equipped on the vertical guide rail
Locating piece with sliding slot；Its welding step includes：A, each car body panel of clamping：Installation fixes bottom plate on workbench, as
The positioning datum of other each car body panels；It respectively puts one block of side plate well on two locating pieces, adjusts the position for indulging locating piece on guide rail,
Clamping two blocks of side plates；It places front and rear panels respectively on two locating racks, adjusts the position of locating rack on cross rail, dress
Front and rear panels are clipped, horizontal location bar and align clamp on two locating racks, clamping top plate are finally utilized；B, welding is each
Car body panel：Successively with argon arc welding point weld each car body panel between junction both ends and centre, clamp each positioning again
Clamp will carry out seam weld with argon arc welding between each car body panel successively；C, after welding treatment：It is each in the vehicle body that step B is welded
A commissure carries out the polishing of appearance using grinding wheel, and each locating clip is unclamped in the weld seam disengaging sand paper polishing for milled of fighting each other later
Pincers, running fix block and locating rack make the vehicle body being welded unclamp, sling vehicle body with suspension arm and unload.
Its existing deficiency is to be unable to doubling production, low production efficiency.
Invention content
It can be multiple with doubling general assembly production according to the above-mentioned deficiencies in the prior art, the purpose of the present invention is to provide one kind
Model improves the novel electric vehicle automobile body welding method of electric vehicle production efficiency.
The technical solution adopted by the present invention to solve the technical problems is：Novel electric vehicle automobile body welding method, including
It is total to spell tooling and workbench, total spelling tooling is set on workbench, it is characterised in that：When carrying out total welding and connecing first by gusset
Inner panel assembly, roof bow and floor pan assembly are welded as body frame in always spelling tooling, then will always spell tooling opening,
Making vehicle body is fixed with body frame in left and right side-wall outer-plate assembly, and vehicle body is fixed with head cover outside plate as hired car body
Assembly, then packet body assembly and car door assembly, front anti-collision beam installation assembly, the secondary total spelling of subframe installation assembly progress.
The floor pan assembly be will include forward engine room assembly, preceding floor and centre gangway, floor assembly, in after floor it is total
At, left and right floor side member assembly, squab panel assembly, torsion beam assembly and rear floor panel assembly be stitched together.
The forward engine room assembly be will include shock absorber support assembly, front longitudinal girder inner plate assembly, front wall assembly and preceding vertical
Beam reinforcing plate is stitched together.
The front wall assembly is that will exist including longeron crossbeam assembly and holder, 2 pieces of front panels and air cartridge splicing
Together.
The floor pan assembly includes battery pack, and battery pack is that battery pack mounting rail assembly, holder are stitched together.
Advantageous effect is possessed by novel electric vehicle automobile body welding method of the present invention：Welding sequence is compared with traditional vehicle difference
Place is side-wall inner-plate when carrying out total welding and connecing first, roof bow, and floor assembly is welded as vehicle body always spelling in tooling
Then left and right side-wall outer-plate is fixed, carries out secondary total spelling by skeleton by total tooling opening of spelling.The advantage of total spelling scheme be into
When driving type appearance remodifies, total tooling need not be spelled, it can be achieved that the conllinear pattern of two vehicles re-designing.It should
Scheme can effectively reduce Productive statistics, while also can shorten the development cycle.
Specific implementation mode
The embodiment of the present invention is described further below：
Embodiment 1：
Novel electric vehicle automobile body welding method, including tooling and workbench are always spelled, total spelling work is set on workbench
Side-wall inner-plate assembly, roof bow and floor pan assembly are first welded as vehicle body by dress when carrying out total welding and connecing in always spelling tooling
Then skeleton will always spell tooling opening, left and right side-wall outer-plate assembly and body frame are fixed making vehicle body, vehicle body with
Head cover outside plate is fixed as packet body assembly, then packet body assembly and car door assembly, front anti-collision beam installation assembly, secondary vehicle
Frame installation assembly carries out secondary total spelling.
Floor pan assembly be will include forward engine room assembly, preceding floor and centre gangway, floor assembly, in after floor assembly, a left side
Right floor side member assembly, squab panel assembly, torsion beam assembly and rear floor panel assembly are stitched together.
