This locate mode not only need be provided with connecting bore on positioning tool 3 before and after the top cover, and need corresponding on the side wall assembly frock pin that matches with connecting bore be set, so frock is complicated, cost is high.
The utility model content
In view of this, the purpose of the utility model is to provide a kind of automobile top-cap and the gusset location structure at fore-and-aft direction, to reduce frock complexity and frock cost.
For achieving the above object, the utility model provides a kind of automobile top-cap and the gusset location structure at fore-and-aft direction, but but comprise the limited step of limit, top cover outer front end and the limited step of limit, gusset outer front end; But but the limited step of the limited step of limit, said top cover outer front end and limit, gusset outer front end is had a common boundary place's lap fit at fore-and-aft direction.
Preferably, but the limited step of limit, said top cover outer front end comprise: first upper table surface, first following table and first step face; Said first upper table surface is connected through the first step face with first following table, and first step face and the first upper table surface junction have chamfering on first, has chamfering first time with the first following table junction.
Preferably; But the limited step of limit, said gusset outer front end comprises: with second upper table surface of the first upper table surface lap fit, with second following table of the first following table lap fit, and have a common boundary the second step face of place's lap fit at fore-and-aft direction with the first step face; Said second upper table surface is connected through the second step face with second following table, and second step face and the second upper table surface junction have chamfering on second, has chamfering second time with the second following table junction.
Preferably, said second step face and gusset main body junction are provided with the side chamfering.
Preferably, said top cover and gusset chamfering cooperation place on chamfering and second on said first has fine gap, has fine gap in said first time chamfering and second time chamfering cooperation place.
Preferably, the angle of said first step face and first upper table surface is identical with the angle of the said second step face and second upper table surface, and is the obtuse angle greater than 90 degree.
Visible by above-mentioned technical scheme; This automobile top-cap of the utility model and gusset are at the location structure of fore-and-aft direction; But but the limited step of limited step through limit, top cover outer front end and limit, gusset outer front end is had a common boundary the no gap lap fit at place at fore-and-aft direction, realizes the location.That is to say that the utility model utilizes the architectural feature of part itself to guarantee the location of fore-and-aft direction, therefore, need not design fore-and-aft direction locating dowel pin on frock, has simplified frock, has reduced the frock cost.

The specific embodiment
This automobile top-cap of the utility model and gusset be at the location structure of fore-and-aft direction, but but the limited step of limited step through limit, top cover outer front end and limit, gusset outer front end is had a common boundary the no gap lap fit at place at fore-and-aft direction, realize the location.
Below lift a specific embodiment and, the utility model is elaborated with reference to accompanying drawing.
The location structure of present embodiment is referring to Fig. 3, and the left side of Fig. 3 is the connecting bridge structural representation of top cover, and the right side is the connecting bridge structural representation of gusset.
As shown in Figure 3, but the front end on the limit, top cover 1 outer 10 of present embodiment and the connecting bridge on limit, gusset outer 20 are provided with a limited step, and this step comprises: first upper table surface 11, first following table 12 and first step face 13.Said first upper table surface 11 is connected through first step face 13 with first following table 12, and first step face 13 and first upper table surface, 11 junctions have chamfering on first, has chamfering first time with first following table, 12 junctions.
Be provided with a limited step but the front end on the limit, gusset 2 outer 20 of present embodiment is corresponding with the connecting bridge on limit, top cover 1 outer 10; This step comprises: is used for second upper table surface 21 of first upper table surface, 11 lap fit, is used for second following table 22 with the first following table lap fit, and the second step face 23 that is used for having a common boundary at fore-and-aft direction with first step face 13 place's lap fit.Said second upper table surface 21 is connected through second step face 23 with second following table 22, and second step face 23 and second upper table surface, 21 junctions have chamfering on second, has chamfering second time with second following table, 22 junctions.
In the present embodiment, the second step face 23 on the first step face 13 on limit, top cover 1 outer 10 and the angle of first upper table surface 11 and limit, gusset 2 outer 12 is identical with the angle of second upper table surface 21, is generally the obtuse angle greater than 90 degree.
As shown in Figure 3, said second step face 23 is provided with side chamfering 231 with gusset main body junction, is used to realize the smooth connection of second step face 23 and gusset main body.
Present embodiment realizes that the locate mode of top cover 1 and gusset 2 is referring to Fig. 4; Fig. 4 first half left side shows the position of location structure in car load of the utility model; First half right side is a top cover and birds-eye view after gusset is connected; Fig. 4 lower part left side is prior art A-A place cross-sectional view, and Fig. 4 lower part right side is the utility model A-A place cross-sectional view.
As shown in Figure 4, top cover 1 has a step to prior art at the A-A place, and gusset 2 also has a step, but the step of top cover 1 has a bigger gap 3 with the step of gusset 2 after being connected.In this case, can only adopt the conventional positioning mode to realize the location of top cover and gusset.
And visible by Fig. 4 lower part right part of flg, top cover 1 all has a limited step with gusset 2 to present embodiment at A-A place, and the step surface of the step surface of top cover 1 and the angle of upper table surface and gusset 2 is identical with the angle of upper table surface, is generally the obtuse angle of spending greater than 90.Because the angle of the step surface of top cover 1 is identical with the angle of the step surface of gusset 2, makes top cover 1 and gusset 2 after being connected, have a faying surface 4, only the chamfering place is not overlapping with following chamfering place on top cover 1 and gusset 2.That is to say that top cover and gusset chamfering cooperation place on chamfering and second on said first has fine gap, have fine gap in said first time chamfering and second time chamfering cooperation place.
Use the location structure of present embodiment; The position fixing process that top cover is placed on the gusset is: robot gripping's top cover slowly moves in the past backward, when the step surface on the top cover is run into the step surface on the gusset, then stops to move; Just accomplished the fore-and-aft direction location this moment, just can begin welding.
Visible by the above embodiments, this automobile top-cap of the utility model and gusset be at the location structure of fore-and-aft direction, utilizes the architectural feature of part itself to guarantee the location of fore-and-aft direction.Therefore, need not design fore-and-aft direction locating dowel pin on frock, simplified frock, reduced the frock cost.
