Abstract
The utility model discloses a kind of welded nut, its nut body comprises flange body, and the side of flange body is panel beating faying surface, is provided with boss in the middle of panel beating faying surface, be provided with pedestal along on the panel beating faying surface of boss periphery, the center of boss is provided with tapped through hole.The utility model can effectively improve welding production efficiency, reduces welding cost, and can carry out repair welding processing to solder skip nut; Can have insulator coating welding to panel beating reverse side, and required welding equipment is simple, easy and simple to handle, weld strength is high, and applicable various sheet metal part is fixedly connected with nut, easy to utilize.
Description
Technical field
The utility model relates to metal fastenings, specifically relates to a kind of welded nut being applicable to only have on the sheet metal part of one-sided weld pass.
Background technique
In automobile manufacturing process, the sheet metal part not having bilateral weld pass is wanted welded nut very difficult.Occur nut solder skip through being everlasting or need repair welding after coming off, but nut is in cavity, welding cannot be implemented.Current common welded nut adopts the welding of nut projection welding machine, but also has following drawback: 1, sheet metal part both sides all need larger weld pass; 2, sheet metal part needs to be raised to certain height and welds; 3, by nut projection welding machine structural limitations, need the size of sheet metal part can not be too large; 4, repair welding difficulty after nut solder skip; 5, panel beating reverse side has the insulators such as coating, welding difficulty; 6, super thick panel beating electric current punctures the problems such as difficulty.
Summary of the invention
The purpose of this utility model is for problems of the prior art, provides a kind of novel welded nut, solves the difficulty that sheet metal part only has welded nut on one-sided weld pass, large-scale sheet metal part; And repair welding after nut solder skip, panel beating reverse side puncture the problem of the general welded nut performance difficulties such as difficulty just like the super thick panel beating electric current of the insulators such as coating.
The utility model takes following technological scheme to realize above-mentioned purpose.Welded nut, its nut body comprises flange body, and the side of flange body is panel beating faying surface, and be provided with boss in the middle of panel beating faying surface, be provided with pedestal along on the panel beating faying surface of boss periphery, the center of boss is provided with tapped through hole.
The utility model can effectively improve welding production efficiency, reduces welding cost, and can carry out repair welding processing to solder skip nut; Can have insulator coating welding to panel beating reverse side, and required welding equipment is simple, easy and simple to handle, weld strength is high, and applicable various sheet metal part is fixedly connected with nut, easy to utilize.

In figure: 1. nut body, 11. panel beating faying surfaces, 12. boss, 13. pedestals, 14. flange bodies, 2. bolt, 3. sheet metal part, 4. mounted piece.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.See Fig. 1 to Fig. 4, welded nut, its nut body 1 comprises flange body 14, the side of flange body 14 is panel beating faying surface 11, be provided with boss 12 in the middle of panel beating faying surface 11, be provided with pedestal 13 along on the panel beating faying surface 11 of boss 12 periphery, the center of boss 12 is provided with tapped through hole.
embodiment:flange body 14 side of its nut body 1 of the utility model is panel beating faying surface 11, the central authorities of panel beating faying surface 11 are provided with boss 12 with threaded hole, and have three pedestals 13 to be distributed in equilateral triangle on the outer panel beating faying surface 11 peripherally of the boss 12 being threaded hole.Sheet metal part 3 punch process have one with nut flange body 14 thickness, sizable heavy stand, and be processed with a through hole corresponding with boss 12 outer circumference diameter in the centre of heavy stand, can ensure that the attachment face of welding back nut body 1 is concordant with surrounding sheet metal part 3.Switch on power between nut body 1 of the present utility model and sheet metal part 3, form loop, through pressurizeing instantaneously and discharging, produce high temperature at pedestal 13 place, after pedestal 13 high temperature melt, nut body 1 is welded on (as shown in Figure 4) on sheet metal part 3; Mounted piece 4 offers a hole more bigger than bolt 2, by the connection of bolt 2 with tapped hole in nut body 1 boss 12, realizes mounted piece 4 and is fixedly connected with sheet metal part 3.
