Abstract
The invention relates to a connecting structure of a hood hinge mounting plate and a side body outer plate of an automobile. The connecting structure comprises the hood hinge mounting plate, the side body outer plate and a side body front connecting plate connected to the side body outer plate; a hood hinge mounting plate front edge is in lap joint with a side body front connecting plate flanging; and the right side of the hood hinge mounting plate is connected to the side body outer plate through a connecting support. The connecting structure can solve the problem that due to the fact that the hood hinge mounting plate is directly welded to the side body outer plate, no spot welding channel exists; the connecting structure is beneficial to arrangement of spot welding; and a series of welding quality problems caused by CO2 gas-shielded welding can be solved.
Description
Technical field
The present invention relates to automotive body structure, be specifically related to the connection structure of automobile front hood hinge adapter plate and side-wall outer-plate.
Background technology
At present, automobile front hood hinge adapter plate with install between side-wall outer-plate be connected time, the direct connection mode of usual employing, as shown in Figure 1, comprise front hood hinge adapter plate front to fit with connecting panel flange before gusset 31 along 12 and weld, also be provided with former welding flange 11 on the right of front hood hinge adapter plate 1, and be welded to connect with side-wall outer-plate 2 by former welding flange 11.This connection mode is due to space and structural limitations, the welding gun passage of spot welding is not implemented between the former welding flange 11 of front hood hinge adapter plate right-hand member and side-wall outer-plate, therefore spot welding can not be adopted on body in white welding line to connect, after body in white weld line completes, CO can only be implemented at special repair welding station by workman
2gas shield welding connects.This connection structure difficult quality guarantee and welding conformability poor, and there is certain hidden danger, it is specific as follows to there is shortcoming in it: (1) adopts the ductility such as DC06 better because side-wall outer-plate material but the sheet material that rigidity is more weak, and sheet metal thickness mostly is 0.6mm or 0.7mm light sheet, and the front hood hinge adapter plate sheet material adopting the good rigidly such as DC01 or high strength steel more, and material thickness mostly is more than 1.2mm, like this, the plate property that front hood hinge adapter plate and side-wall outer-plate adopt and expect thick differing greatly, adopts CO between the two
2during gas shield welding welding; local, easy the destructive characteristics more weak and side-wall outer-plate junction that sheet material is thinner plate property; when welding quality is bad; even occur the phenomenon of side-wall outer-plate local burn-through; in road examination and real vehicle use procedure, there is indivedual side-wall outer-plate and be welded to connect place's local laceration phenomenon.(2) CO
2gas shield welding is manual operation welding, and because workman's skill level is different with technical ability height, its conformability is poor, and weld seam is comparatively obvious, attractive in appearance not, and productive temp is slower.
Summary of the invention
The object of the present invention is to provide the connection structure of a kind of automobile front hood hinge adapter plate and side-wall outer-plate, it can solve because front hood hinge adapter plate directly welds with side-wall outer-plate and cause not having the problem of spot welding passage, is conducive to arranging spot welding, to avoid adopting CO
2a series of problems of welded quality that gas shield welding brings.
The connection structure of automobile front hood hinge adapter plate of the present invention and side-wall outer-plate, connecting panel before comprising front hood hinge adapter plate, side-wall outer-plate and being connected to the gusset on side-wall outer-plate, described front hood hinge adapter plate front along with gusset before connecting panel flange overlap, it is characterized in that: being connected on side-wall outer-plate by a connection bracket of described front hood hinge adapter plate.
Further, the right of described connection bracket is provided with the first riser, back is provided with the second riser, and is welded on side-wall outer-plate by the first riser and the laminating of the second riser; Be provided with clinch in the front of connection bracket, and fitted with connecting panel flange before gusset by clinch and weld; The right of described front hood hinge adapter plate is welded in connection bracket.
Further, the middle part of described connection bracket is provided with rack positioning hole, is convenient to the Set and Positioning of this connection bracket in technique welding process.
Welding step of the present invention is as follows:
First, be welded to connect support: the first riser of connection bracket and the relevant position of the second riser and side-wall outer-plate are fitted, fitted by connecting panel flange before the clinch of connection bracket and gusset, weld in spot welding mode.
Then, welding front hood hinge adapter plate: ride on the rack body of connection bracket by the right of front hood hinge adapter plate, by front hood hinge adapter plate front along riding over before gusset on connecting panel flange, welds in spot welding mode.
The present invention has the following advantages: realize indirectly being connected by connection bracket with the junction of side-wall outer-plate at front hood hinge adapter plate, connection bracket is first welded on side-wall outer-plate and forms a branch unit by it, and then weld with front hood hinge adapter plate, this addresses the problem the problem causing not having spot welding passage when front hood hinge adapter plate directly welds with side-wall outer-plate due to the impact of peripheral parts, be convenient to adopt spot welding to weld, avoid with CO
2the problems such as the local burn-through phenomenon that gas shield welding mode occurs when welding and welding conformability difference, effectively improve the welding quality of front hood hinge adapter plate and side-wall outer-plate connection structure, achieve stable also failure-free therebetween and connect.Welding manner in the present invention is spot welding, adopts automatic mechanical arm welding, can ensure welding quality and aesthetic property, and improve rhythm of production.
