Background technique
Along with the development of auto technology, the Security of automobile circuit system also draws attention day by day, by car load earth point rational deployment, guarantee car load electric potential balancing, in meeting basic electrical function requirement, more be conducive to the Electrical Safety of each module, avoid potential shift, evade the appearance of the problems such as electromagnetic interference.
Use ground connection weld bolt to connect each electrical equipment as circuit link guide pillar, it is the preferred option that guarantees each electrical equipment electric potential balancing, this kind of mounting type, requires high to ground connection weld bolt assembly: especially the perpendicularity of bolt welding, position degree require high, and definitely can not rosin joint.
Along with the market demand of energy-conserving and environment-protective grows to even greater heights, passenger car lightweight requirements has become world car development trend, so depot is in the situation that guaranteeing its intensity, steel plate design is more and more thinner, this has just proposed challenge to the welding procedure of weld bolt, according to the needs of design, require a kind of ground connection weld bolt of exploitation can meet the requirement of welding in thin plate and cylinder tubing cambered surface.
Summary of the invention
The object of the present invention is to provide a kind of ground connection weld bolt assembly, it can meet the requirement of welding in the thin plate of 0.6mm thin plate and above thickness and cylindrical tubing cambered surface.
In order to achieve the above object, the present invention is achieved in that
For 0.6mm and with the ground connection weld bolt assembly of upper thin sheet, it comprises ground connection weld bolt, flange sheath nut; Described ground connection weld bolt comprises welding fusing point, flange, for the anistree shaft shoulder of conjunction cable with there is externally threaded screw rod; Described flange sheath nut comprises that the internal thread corresponding with external thread of screw, flange sheath nut rotation set are on ground connection weld bolt, and both flange interfaces fit tightly; The welding fusing point of ground connection weld bolt comprises a bihexagonal cylinder soldering tip, and the cylinder soldering tip end of telling is a striking district, is specially, and the top of cylinder soldering tip is taper type, and the top of cylinder soldering tip is circular arc.
Described for 0.6mm and with the ground connection weld bolt assembly of upper thin sheet, the outside thread of ground connection weld bolt screw rod is M-point guide thread.
The present invention adopts above-mentioned design, design by the welding fusing point emphasis to ground connection weld bolt, thereby improved the stability of welding earth stud in 0.6mm thin plate, circular arc pipe fitting surface soldered, make rosin joint rate trend towards zero, greatly improve working efficiency, reduced failure risk.

Embodiment
Further illustrate the present invention by specific embodiment below.
As shown in Figure 1, a kind of ground connection weld bolt assembly, comprises flange sheath nut 10, ground connection weld bolt 30.Described flange sheath nut 10 comprises the internal thread 14 in hexagonal top 11, cylinder body 12, nut flange 13 and nut flange 13; Described ground connection weld bolt 30 comprises that the outside thread employing M-point guide thread 31 having with on the corresponding externally threaded screw rod 32 of flange sheath nut 10 internal thread 14, described screw rod 32 is top; Be positioned at screw rod 32 bottoms the anistree shaft shoulder 33, be positioned at the bolt flange 34 of the anistree shaft shoulder 33 bottoms and be positioned at the welding fusing point 35 of bolt flange 32 bottoms.The internal thread 14 of flange sheath nut 10 is corresponding screw pair with screw rod 32 outside threads, guarantees that flange sheath nut 10 can screw in ground connection weld bolt 30 and play the role of fastening.
As shown in Figure 2, welding fusing point 35 comprises that a cross section is bihexagonal cylinder soldering tip 36, and cylinder soldering tip 36 ends of telling are striking districts 37, are specially, and the top of cylinder soldering tip 36 is taper type, and the top of cylinder soldering tip 36 is circular arc.When flange sheath nut 10 just assembles with ground connection weld bolt 30, hexagonal abutment sleeve 41 pushes up 11 fastening flange sheath nuts 10 by hexagonal.Aerodynamic moment rifle is by 12 jiaos of sleeves, 42 twisting cylinder soldering tips 36 and guide with the M-point guide thread 31 at screw rod 32 tops, makes ground connection weld bolt 30 screw in smoothly flange sheath nut 10 fastening.The upper plane of the bolt flange 34 on the lower plane of the nut flange 13 on flange sheath nut 10, welding earth stud 30 is all perpendicular to axis, and after flange sheath nut 10, ground connection weld bolt 30 are fastening, two flange junction planes fit tightly seamless.
As shown in Figure 3, elasticity soldering set chuck 43 is by adopting cylinder body 12 location to capture flange sheath nut 10, ground connection weld bolt 30, and automatic or manual has operated the welding process of welding earth stud 30 on various thin plate and tubing 44 arc surfaces.The circular flat medial axis in cylinder body 12 medial axis and the striking district 37 at welding earth stud top during simultaneously with screw rod 32 axis coaxle, guarantees accurate positioning.
As shown in Figure 4, be the final assembling condition of ground connection weld bolt assembly, be welded on the ground connection weld bolt prepackage accessory on sheet metal part, the nut of back-outing.Be inserted in after wire connecting sheet, aerodynamic moment rifle twisting nut hexagonal top 11 guides with M-point guide thread 31, makes flange sheath nut 10 screw in smoothly ground connection weld bolt 30 and fasteningly complete assembling.The described anistree shaft shoulder 33 is measure-alike with the anistree endoporus of connecting sheet 21, plays anti-rotation, positioning action after connecting sheet 21 is inserted in.
The present invention adopts said modules, and its advantage is:
1, ground connection weld bolt screw rod 32 axis are perpendicular to bolt flange 34 planes, internal thread 14 axis of flange sheath nut 10 are perpendicular to the axis of flange sheath nut 10, after guaranteeing that ground connection weld bolt 30 and flange sheath nut 10 are fastening, the combination of two Flange Plane can fit tightly seamless.
2, the welding fusing point 35 of ground connection weld bolt 30 adopts bihexagonal cylinder soldering tip 36 structures, when twisting can take into account ground connection weld bolt 30 simultaneously and combine with flange sheath nut 10 time and welding, increase by 7% bonding area and increase by 50% periphery curvature than the hexagonal soldering point of same S face and reach the object that strengthens welding robustness, and general hexagon head or the design of socket cap solder joint cannot meet two requirements simultaneously.
3, ground connection weld bolt 30 and flange sheath nut 10 carry out preassembly by pre-clamping apparatus and reach stable fastening and exit and loosen moment of torsion, and the cylindrical shape axis of flange sheath nut 10 is coaxial with ground connection weld bolt screw rod 10.The welding fusing point 36 of ground connection weld bolt 30 is with the striking district 37 of the conical surface and circular flat.Guarantee that welding robot captures while location with the cylinder of flange sheath nut, the fusing point striking welding position of welding earth stud keeps minimum millet cake contact to steel plate, to avoid arcing rosin joint phenomenon.
4, the anistree shaft shoulder 33 of ground connection weld bolt supports the use with corresponding anistree hole wire connecting sheet, guarantees that wire contact pin can transfer and deviation post in fastening nuts process.Can meet small angle transposition, avoid stopping impact simultaneously.
