Abstract
The utility model relates to a hexagonal projection welding nut of a sealing structure. The middle part of the nut is a circular shoulder. The hexagonal projection welding nut is characterized in that the welding part of the projection welding nut is a raised circular ring, and the shape of the upper part of the nut is a hexagon. The hexagonal projecting welding nut has the characteristics of high speed and low cost of detecting the torsion strength of the welding nut in an on-site manner. As the welding part of the projection welding nut is the raised circular ring, the sealing at the position of a welding seam after welding is ensured. As the upper half part of the projection welding nut adopts the shape of the hexagon, the test of welding intensity can be carried out at the production field. The hexagonal projection welding nut solves the problem that the present circular projection welding nut cannot carry out on-site test of welding intensity.
Description
Technical field
The utility model belongs to the technical field of automobile nut, particularly a kind of sealing configuration six side's project-welding nuts.
Background technique
Welded nut is a kind of important fastening piece on the automobile, a nearly hundreds of project-welding nut on the car.Require its weld strength height, screw thread can not produce distortion during welding, and spatter can not adhere on the screw thread, and the twisting strength of welding effect can be checked.The welded nut that uses in the automobile production at present is the project-welding nut of four spot welding mostly, 4 salient point fusings fuse with base plate during welding, does not melt at other positions, when the local time postwelding that is applied in sealing requirements can not satisfy sealing requirements in gap air intake and the infiltration between the weld salient point.
External automobile industry to the solution that this problem adopts is: the round welded nut that adopts the bulge loop structure, though this method can solve sealing problem, but because external form is circular, can't carry out the situ strength check after the welding, and do not form series, need these series product of exploitation and solve the weld strength check problem of production scene.
Summary of the invention
The utility model purpose provides a kind of sealing configuration six side's project-welding nuts.
The technical solution of the utility model is achieved in that
Sealing configuration six side's project-welding nuts, its intermediate portion is the circle shoulder, and it is characterized by: the welding part of described project-welding nut is the annulus of a projection, and the top profile of nut is a hexagon.
It is fast to the utlity model has field test welded nut twisting strength speed, and the low characteristics of cost.Because the welding part of project-welding nut is the annulus of a projection, has guaranteed the sealing of postwelding weld joint.Because upper half part of project-welding nut adopts hexagon, can carry out the weld strength check in the production scene.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a superstructure schematic representation of the present utility model.
Specific embodiments
Describe specific embodiments of the present utility model in detail below in conjunction with accompanying drawing.
Sealing configuration six side's project-welding nuts, its intermediate portion is circle shoulder 1, and it is characterized by: the welding part of described project-welding nut is the annulus 2 of a projection, and the top profile of nut is a hexagon 3.
As depicted in figs. 1 and 2, sealing configuration six side's project-welding nuts are M6～M12 series product.At first select the fastening piece material of the good and bulge loop good moldability of weldability, determine the diameter of the annulus 2 of projection, highly according to the required weld strength of product and sealing requirements, determine annulus 2 sectional shapes of projection and annulus 2 top dimension of projection according to welding procedure characteristic, and finally determine the structure and the size of nut by soldering test and quality analysis.According to the principle of saving material as far as possible, the nut upper design is become hexahedron, circle shoulder and protruding welding ring, upper half part of nut is hexagon 3, and intermediate portion is circle shoulder 1, and the bottom is divided into annulus 2.Conducting welding current when weld the rounded shoulders position, the welding part is the annulus 2 of a projection, the annulus 2 of the whole projection in welding back and base plate fusion, the weld joint is water-tight, air tight after can welding, and has guaranteed the sealing of weld.Upper half part of project-welding nut is designed to hexagon, not only adopts at the scene to turn round and refuses spanner and just can carry out Weld Quality Inspection, and can shorten Check-Out Time, is approximately 1 minute Check-Out Time.Lower half portion of project-welding nut is designed to bulge loop, can guarantee project-welding nut welding after, have sealing function.
It is respond well that the utility model is applied in positions such as passenger-car chassis, vehicle light support, vehicle body.
Claims (1)
1, sealing configuration six side's project-welding nuts, its intermediate portion is circle shoulder (1), and it is characterized by: the welding part of described project-welding nut is the annulus (2) of a projection, and the top profile of nut is hexagon (3).
