Abstract
The utility model discloses a welding structure of an automobile front floor assembly. The welding structure comprise a front floor (1), a left front seat cross beam (2) and a right front seat cross beam (3) which are welded above the front floor (1), and a front end reinforcement plate (4) which is welded below the front floor (1); the left front seat cross beam (2) and the right front seat cross beam (3) are symmetrically arranged on left and right sides of the front floor (1); and welding positioning protruded points (5) which are distributed along welding edges at intervals are arranged at the welding positions of the left front seat cross beam (2), the right front seat cross beam (3) and the front end reinforcement plate (4) and on the front floor (1). The welding positioning protruded points are used as welding guide marks, the welding positions can be determined according to the welding positioning protruded points during welding, the front floor is not needed to be rotated, a welding clamp head is not needed to be assisted manually, and parts of front and reverse faces can be welded on the front face, and the welding structure is ingenious in design and novel in conception.
Description
Technical field
The utility model relates to auto parts and components, specifically, is a kind of welded structure of automobile front floor assembly.
Background technology
The automobile front floor assembly is made up of preceding floor 1, left front seat crossbeam 2, right front seat crossbeam 3, front end brace panel 4, and four are the steel plate punch forming.Left front seat crossbeam 2, right front seat crossbeam 3 are welded on the top on preceding floor 1 and are symmetrical set, and are respectively applied for left front seat and right front seat are installed; Front end brace panel 4 is welded on the below on preceding floor 1 and is positioned at the front end on preceding floor 1, strengthens the front end intensity on preceding floor 1.
On the plate 1 this bigger part, need the tow sides soldering part previously, positive part is owing to can see the position of weld; Welding is than being easier to; And the part of reverse side welds very difficulty owing to can't see the position of weld in the front, and solution commonly used has two kinds:
(1) makees a switching mechanism, utilize switching mechanism to overturn 180 ° after positive part weld, weld again after making the part of reverse side be turned to the front.Shortcoming: make a switching mechanism in addition, increase cost; The upset welding, efficient is low.
(2) adopt two people's co-operatings, promptly a people reverse side will weld an end position of chuck definite after, weld to reverse side by another people.Shortcoming: artificial auxiliary welding chuck location is very dangerous, inadvisable; Increase the cost of labor in the welding.
The utility model content
The purpose of the utility model provides a kind of automobile front floor assembly welded structure, easy to operate, safety, and efficient is high, cost is low.
For solving above technical matters; A kind of automobile front floor assembly welded structure that the utility model provides; Comprise preceding floor (1); Be welded on left front seat crossbeam (2), the right front seat crossbeam (3) of top, preceding floor (1); Be welded on the front end brace panel (4) of below, preceding floor (1), said left front seat crossbeam (2), right front seat crossbeam (3) are symmetricly set on the left and right sides of preceding floor (1), and key is: said preceding floor (1) is provided with along the spaced apart welding positioning convex point of welded edge (5) at the place, position of weld of left front seat crossbeam (2), right front seat crossbeam (3), front end brace panel (4).
As preferably, said welding positioning convex point (5) is a circular protrusions, this welding positioning convex point (5) and preceding floor (1) integrated punching moulding, and the welding accuracy of positioning is high, and has reduced technology, has reduced manufacturing cost.
Be respectively arranged with the welding positioning convex point of left front seat crossbeam, right front seat crossbeam, front end brace panel previously on the plate; As the welding leader label; When welding, just can confirm the position of weld according to the welding positioning convex point; Need not overturn preceding floor, do not need artificial auxiliary welding chuck yet, just can accomplish the welding of positive and negative two surface parts in the front, design ingenious, novel.Beneficial effect: do not need switching mechanism, reduced equipment cost, improved production efficiency; Do not need artificial auxiliary welding chuck, reduced cost of labor and more convenient operation, safety.

Fig. 2 is the back view of Fig. 1.
Fig. 3 is the A portion enlarged drawing of Fig. 1.
Fig. 4 is Fig. 2
BPortion's enlarged drawing.
Fig. 5 is the exploded drawings of the automobile front floor assembly before improving.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further:
Like Fig. 1, automobile front floor assembly welded structure shown in Figure 2, constitute by preceding floor 1, left front seat crossbeam 2, right front seat crossbeam 3, front end brace panel 4, four are the steel plate punch forming.The rear and front end of left front seat crossbeam 2, right front seat crossbeam 3 is provided with flange, and both are welded on the top on preceding floor 1 through flange separately.Left front seat crossbeam 2, right front seat crossbeam 3 are symmetricly set on the left and right sides on preceding floor 1, are respectively applied for left front seat and right front seat are installed.Also be provided with flange on the front end brace panel 4, be welded on the below on preceding floor 1 through its flange, front end brace panel 4 is positioned at the front end on preceding floor 1, strengthens the front end intensity on preceding floor 1.The above with improve before the automobile front floor assembly identical.
Difference is: combine Fig. 1, Fig. 2, Fig. 3 to know, preceding floor 1 respectively is provided with 12 along the spaced apart welding positioning convex point 5 of welding edge at the place, position of weld of left front seat crossbeam 2, right front seat crossbeam 3.Can know that in conjunction with Fig. 1, Fig. 2, Fig. 4 preceding floor 1 is provided with five along the spaced apart welding positioning convex point 5 of welding edge at the place, position of weld of front end brace panel 4.The quantity of welding positioning convex point 5 is set according to the size at place, position of weld.
Welding positioning convex point 5 is preferably circular protrusions, and should welding positioning convex point 5 and the 1 integrated punching moulding of preceding floor.
Claims (2)
1. automobile front floor assembly welded structure; Comprise preceding floor (1); Be welded on left front seat crossbeam (2), the right front seat crossbeam (3) of top, preceding floor (1); Be welded on the front end brace panel (4) of below, preceding floor (1); Said left front seat crossbeam (2), right front seat crossbeam (3) are symmetricly set on the left and right sides of preceding floor (1), it is characterized in that: said preceding floor (1) is provided with along the spaced apart welding positioning convex point of welded edge (5) at the place, position of weld of left front seat crossbeam (2), right front seat crossbeam (3), front end brace panel (4).
2. according to the described automobile front floor assembly of claim 1 welded structure, it is characterized in that: said welding positioning convex point (5) is circular protrusions, this welding positioning convex point (5) and preceding floor (1) integrated punching moulding.
