Abstract
The utility model provides a welding structure of two stamping parts in mechanical products, which comprises two stamping parts welded into a whole by welded edges; a plurality of sunk convex plates facing the other stamping part are evenly arranged on the welded edge of one stamping part and welding points are arranged on the sunk convex plates. The adoption of the welding structure can improve the strength of the parts; when welding is carried out, the convex plates can be used for positioning so as to ensure correct positioning of a welding gun, and operation is simple and convenient. Besides, as the size of the convex plates is small, thus being easier for processing compared with strip-type bars and lowering mold fabricating complexity so as to lower cost and be capable of solving liquid leakage problem during application process.
Description
Technical field
The utility model relates to the welding technique of sheet metal part in the engineering goods.
Background technique
At present, a lot of engineering goods sheet metal parts adopt welding manner to be linked to be an integral body more.As the traditional welded structure of the sheet metal part of automotive body is that first sheet metal part 2 and second sheet metal part 3 that overlaps mutually designs the welding edge of width greater than 14mm, realizes that by spot-welding technology 1 is solder joint, as shown in Figure 1.Perhaps by improving, in welding edge design bar blocks muscle 4 structures, solder joint 1 is positioned on the piece muscle, as shown in Figure 2.For the former, traditional welding edge structure exists welding gun to be difficult for the location, causes bond pad locations not accurate enough, and the workman operates defectives such as inconvenience and part self intensity is bad.For the latter, increased bar blocks muscle structure, though increased the intensity of part itself,, make manufacturing process complicate because the part complexity has increased the mould manufacture difficulty, increased cost.
Summary of the invention
The utility model proposes the welded structure of two sheet metal parts in a kind of engineering goods at the deficiencies in the prior art, uses the sheet metal part convenient processing and manufacture of this structure, and cost of production is low, can make the welding gun accurate positioning when welding, and is easy and simple to handle.
The technical solution of the utility model is as follows:
The welded structure of two sheet metal parts in the engineering goods comprises that two are welded to each other sheet metal part into integral type by welding edge, wherein evenly is provided with a plurality of sinking boss towards another sheet metal part welding edge on the welding edge of a sheet metal part, and solder joint is positioned on each boss.
The welding of two sheet metal parts has improved the intensity of part itself by adopting the welding edge structure of heavy stand formula, can utilize boss to position when welding, makes the welding gun accurate positioning, and is easy and simple to handle.In addition,, compare easier processing, reduce the mould manufacture difficulty, thereby reduce cost, can also solve leakage problem in the coating process with the bar blocks muscle because the boss area is little.

Embodiment
Referring to Fig. 3, sheet metal part welded structure with vehicle body is an example, it comprises first sheet metal part 2 of U-shaped and second sheet metal part 3 of U-shaped, second sheet metal part 3 is fixed in first sheet metal part 2 by the spot welding mode, on the welding edge of the dual-side of second sheet metal part 3, be respectively arranged with the boss 5 of a plurality of sinkings, the boss bottom is a part circular, and solder joint 1 is positioned on the boss.Boss 5 is that spacing is that 40mm, the high 3mm of being, area are 40mm
2Circular small boss structure.
Claims (2)
1, the welded structure of two sheet metal parts in the engineering goods, comprise that two are welded to each other sheet metal part into integral type by welding edge, it is characterized in that wherein evenly be provided with a plurality of sinking boss towards another sheet metal part welding edge on the welding edge of a sheet metal part, solder joint is positioned on each boss.
2, the welded structure of two sheet metal parts in the engineering goods according to claim 1 is characterized in that: described boss is that spacing is that 40mm, the high 3mm of being, area are 40mm
2Circular small boss structure.
