Abstract
The utility model discloses a square projection-weld nut with locating ends, comprising a nut body and projection-weld points. The structure of the utility model is characterized in that all edges of the nut body is made in a square shape; the projection-weld points are processed in four round lug bosses at the farthest points of the square corners at the bottom of the nut body edges; a protruding locating ring are processed on the bottom outer edge of the central screw of the nut body. Compared with the existing products, the utility model which has a simpler structure and convenience for use solves the problem of the locating of the projection-weld nut and improves the weld strength.
Description
Technical field
A kind of four directions of the utility model band positioning end project-welding nut belongs to processing technique field, and it relates to improvement on the present product structure and the raising on the performance.
Background technique
Project-welding nut is used very extensive on automobile, and bicycle is used nearly 300 the most for a long time, but the nut that projection welding is used on car body, does not normally have positioning boss, and this nut is when projection welding, and the workman is difficult to control, and often weldering needed to detain rectification partially; The hole is poor to neutrality simultaneously, also is difficult for during assembling aligning.In addition, at present the project-welding nut that uses is added the thin thickness of nut because the problem on the structural design own generally has only three projection welding points, has often just caused the join strength after the welding lower, or the like shortcoming.
Summary of the invention
The purpose of this utility model designs at the existing shortcoming of the said goods just a kind of four directions of new structure band positioning end project-welding nut is provided.
The purpose of this utility model realizes by following measure:
This kind four directions band positioning end project-welding nut, it is to be made of basal body of nut and projection welding point, its structural design features is, the periphery of basal body of nut is square shape, and the projection welding point is machined in the distal-most end place at angle, basal body of nut peripheral base four directions and is four roundlet boss shapes, at the positioning ring of the outer rim place processing projection of the bottom of basal body of nut center screw.
The drawing of accompanying drawing is described as follows:
Fig. 1 is a form structure schematic representation of the present utility model
Fig. 2 is a user mode structural representation of the present utility model
Fig. 3 is the cross-sectional view of the utility model basal body of nut
Fig. 4 is the enlarged view of I part among Fig. 3
Embodiment
Below with reference to drawings and Examples the utility model is further described:
Shown in accompanying drawing 1-4,
This kind four directions band positioning end project-welding nut, it is to be made of basal body of nut 1 and projection welding point 2, its structural design features is, the periphery of basal body of nut 1 is square shape, and projection welding point 2 is machined in the distal-most end place at angle, basal body of nut 1 peripheral base four directions and is four roundlet boss shapes, at the positioning ring 4 of the outer rim place processing projection of the bottom of basal body of nut 1 center screw 3.The thickness m of basal body of nut 1 is 4～12mm.Thicker than general nut.The height h1 of positioning ring 4 is 0.9～1.1mm.The height h2 of the 4 projection welding points 2 that process with stamping process is 0.8～1mm, and its maximum cross-section width b is 1～1.5mm.The formed angle α of the outer surface of its outer surface and basal body of nut 1 is 130～140 °.And angle β is about 45 ° between basal body of nut (1) bottom.The utility model product is the series product of a screw thread specification from M4, M5, M6, M8, M10 * 1.25, M12 * 1.25.It both can solve the location of project-welding nut, had improved weld strength again.
During projection welding, the positioning ring 4 of the projection on this basal body of nut 1 matches with the metal sheet bottom outlet and locatees automatically, need not to control, and promptly safety is convenient again; We are for improving the assurance load of nut simultaneously, satisfy with the joining usage requirement of 8 grade bolts, through test for several times, can remedy with low carbon steel without the defective of heat treatment (assurance weldability) by adding big nut thickness m size, especially for M10 * 1.25, its thickness of M12 * 1.25 all greater than common 2 type nuts.
The utility model is compared with existing product to have simple in structurely, easy to use, both can solve projection welding Weld strength has been improved again in the location of nut.
