Description
Technical field
The utility model belongs to new-energy automobile body structure field, and in particular to a kind of cowl upper.
Background technique
Cowl upper is the critical function component of body-in-white structure, is welded with front panel assembly (Dash Panel),
To realize being isolated for cockpit and enging cabin.Traditional cowl upper is generally long strip type, is not easy to position when welding, many
Welding production line uses Docking system, i.e., after robot gripper crawl cowl upper piece uploading, cowl upper is together with handgrip
Together by falling off on robots arm, to realize will there is sufficient positioning between cowl upper and front panel assembly.Which is true
Have good locating effect in fact, guarantees welding quality.But it is welded using which, production line needs to be equipped with expensive robot
And Docking system, it is not cost-effective enough for inexpensive low-producing new-energy automobile, virtually improve new energy
The price of automobile, and reduce its brand competitiveness.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of cowl upper, with the structure of optimization, without
Automatic piece supplying system only needs artificial piece uploading, so that it may which simply its welding positioning between front panel assembly of stable realization is being protected
While demonstrate,proving quality, the input cost of production line is reduced.
In order to achieve the above objectives, the utility model provides the following technical solutions:
A kind of cowl upper, including integrally formed girder, the first flange and the second flange；First flange and master
Beam is set in obtuse angle in front of girder；The vertical girder of second flange is down-set in girder rear；In first flange
Connection sheet there are two portion is arranged symmetrically vertically downward, two sides and girder are arranged symmetrically diagonally downward in obtuse angle, and there are two engaging lugs；
A pilot hole and a location hole are symmetrically offered on second flange；The diameter of the pilot hole is greater than location hole；Institute
It states the second flange rear and is additionally provided with the third flange parallel with girder.
Preferably, the gutter channel of several recess is also provided on second flange.
Preferably, the diameter of the pilot hole is greater than 1~2mm of location hole.
Preferably, the connection sheet, engaging lug and the first flange are integrally formed；The third flange and the second flange one
Molding.
The utility model has the beneficial effects that: realizing by using the cowl upper after optimization structure and facilitating people
Work piece uploading and positioning (XYZ to all have face position, be aided with XY to hole position), guarantee position, and then guarantee welding quality
While, reduce the input cost of production line.
Detailed description of the invention
In order to keep the purpose of this utility model, technical scheme and beneficial effects clearer, the utility model provides as follows
Attached drawing is illustrated:
Fig. 1 is the utility model perspective view；
Fig. 2 is the utility model front view.
It is marked in attached drawing as follows: girder 1, the first flange 2, the second flange 3, connection sheet 4, engaging lug 5, pilot hole 6, positioning
Hole 7, third flange 8, gutter channel 9.
Specific embodiment
Below in conjunction with attached drawing, the preferred embodiment of the utility model is described in detail.
Description below in relation to " forward and backward " direction refers to the front and back along vehicle body direction.
Such as Fig. 1~2, a kind of cowl upper, including integrally formed girder 1, the first flange 2 and the second flange 3；It is described
First flange 2 is set to 1 front of girder with girder 1 in obtuse angle；The vertical girder 1 of second flange 3 is down-set after girder 1
Side；First flange, 2 middle part is symmetrical arranged vertically downward there are two connection sheet 4, and two sides are right diagonally downward in obtuse angle with girder 1
Claiming setting, there are two engaging lugs 5；A pilot hole 6 and a location hole 7 are symmetrically offered on second flange 3；It is described to lead
It is greater than location hole 7 to the diameter in hole 6；Second flange, 3 rear is additionally provided with the third flange 8 parallel with girder 1.
Firstly, front panel assembly has been on welding fixture, then manually by suspender or directly manually by front wall upper cover
Plate is placed in above front panel assembly, and location hole 7 is matched with the positioning pin of fixture where front panel assembly, realization XY to determine
Position, the diameter of pilot hole 6 are greater than location hole 7, therefore are only used as cowl upper and fall into leading for corresponding position positioning pin on fixture
To positioning otherwise will be caused to XY to coarse positioning.
In obtuse angle because of the first flange 2 and girder 1, therefore cowl upper can be carried out from vehicle front to vehicle body rear
Piece uploading smoothly can be easily packed into relatively.
Second flange 3 is vertical with girder 1, and for guarantee location hole 7 can be completely parallel to horizontal direction realize XY to
Positioning, i.e., do not generate any drift angle of Z-direction.
Two connection sheets 4 (will be not shown in the figure, can connect to be conventional with a transition piece being arranged on front panel assembly
Fitting) welding, and then complete to be welded to connect at cowl upper and the first of front panel assembly.Because connection sheet 4 is set vertically downward
It sets, therefore it integrally has certain correcting to cowl upper in the X direction.
Engaging lug 5 is arranged as the first flange 2 with girder 1 in obtuse angle, all will be in the corresponding flange of front panel assembly
It contacts and welds, and then complete to be welded to connect at cowl upper and the second of front panel assembly and at third.And the choosing at obtuse angle
It selects and is arranged, so that only engaging lug 5 can have the positioning action in the direction XZ (if such as connection sheet 4 of engaging lug 5 is vertically arranged, only
There is X-direction positioning action).
The third flange 8 parallel with girder 1 is being contacted and is being welded with the flange of front panel assembly corresponding position, and then complete
It is welded to connect everywhere at cowl upper with the of front panel assembly, the positioning of cowl upper Z-direction can be completed on the whole.
So far, it by using the cowl upper after the above optimization structure, realizes and facilitates artificial piece uploading and positioning (XYZ
To all have face position, be aided with XY to hole position), guarantee position, and then guarantee welding quality while, reduce production
The input cost of line.
Further, the gutter channel 9 of several recess is also provided on the second flange 3 that the present embodiment uses, which sets
Meter, can by after rainwater conflux orderly and not it is rambling import vehicle body drainage system.
Further, the diameter for the pilot hole 6 that the present embodiment uses is greater than 1~2mm of diameter of location hole 7, tolerance choosing
It selects and ensure that location hole 7 and pilot hole 6 simultaneously to XY to positioning, did not avoided positioning, and can absorb production to a certain extent
And the manufacturing tolerance of punching, facilitate assembled in situ to position.
Further, connection sheet 4, engaging lug 5 and the first flange 2 that the present embodiment uses are integrally formed；The third is turned over
Side 8 and the second flange 2 are integrally formed, which improves the consistency of front-wall upper cover plate structure, while being also convenient for producing, and are reduced
The processes such as assembly welding.
Finally, it is stated that preferred embodiment above is merely intended for describing the technical solutions of the present application, but not for limiting the present application, to the greatest extent
Pipe has been described in detail the utility model by above preferred embodiment, but those skilled in the art should manage
Solution, can make various changes, without departing from the utility model claims book institute to it in the form and details
The range of restriction.
