Description
Technical field
The utility model relates to a kind of nut, particularly relates to the fastening self-locking adjustable nut of a kind of welding.
Background technique
In the prior art, it is comparatively extensive that welded nut connects fastening applications at the panel beating of the industry such as automobile, industry, particularly in automobile chassis system with the installation at position, each portion be connected, adopt common welded nut usually can select and the impact such as strength grade of design due to welding precision, the own raw material of welding technique level, welded nut, there will be following a few class problem: one, after welding, the central position of welded nut and assembling set misalignment, cause installing; Two, the height of the Kohlenstoffgehalt in the material selected by different welded nut strength grades, causes the height of weld strength uneven, causes the generation of sealing-off, rosin joint, have a strong impact on the Security of product; Three, due to the quality problems that welded nut is produced, cannot do over again after welding, the operations such as replacing, the phenomenon such as cause that one-piece element is scrapped, causes larger economic loss problem.
Summary of the invention
Technical problem to be solved in the utility model is to provide the fastening self-locking adjustable nut of a kind of welding, which solve the welding technique problem of different materials different intensity grades, can screw in fastening in fast automatic correction location, and quick-replaceable and rework issues can be realized, the application of welding in fastening field at the panel beating such as automobile, industry is of great significance with popularization tool.
The utility model solves above-mentioned technical problem by following technical proposals: the fastening self-locking adjustable nut of a kind of welding, it is characterized in that, it is welded stamping by the self-locking nut body of cold-heading molding form with stamping forming, and the self-locking nut body of cold-heading molding is fastened in stamping forming welding stamping;
The self-locking nut body of cold-heading molding comprises self-locking nut housing, self-locking thread, cubic flange body, and self-locking nut housing and cubic flange body are fixed, and self-locking thread is positioned at self-locking nut housing;
Stamping forming welding stamping comprises face of weld, spacing leg, the centre of face of weld is provided with a cubic penetration hole, the diameter of four directions penetration hole is greater than the diameter of self-locking thread, four angles of face of weld are respectively equipped with four circular weld salient points, and two spacing legs form an oval breach.
Preferably, the other end of described self-locking thread is provided with the counterbore that is greater than self-locking thread external diameter.
Preferably, the external shape of described self-locking nut housing is circular or polygonal.
Positive progressive effect of the present utility model is: the utility model solves in the prior art because welding positioning precision problem causes regulating, causes the problem that cannot install.The utility model can screw in fastening in fast automatic correction location, and can realize quick-replaceable and rework issues, and the application of welding in fastening field at the panel beating such as automobile, industry is of great significance with popularization tool.The utility model can carry out disassembled simply and replacing, convenient for maintaining.Self-locking thread has certain activity space, realize automatic adjustment and lock performance fast, as occurred, quality is reprocessed or thread failure, only the spacing leg instrument adjustment of welding stamping need be taken out nut carry out replacings reset limit can, effectively reduce be correlated with do over again, the expense such as to scrap.

Embodiment
The utility model preferred embodiment is provided, to describe the technical solution of the utility model in detail below in conjunction with accompanying drawing.
As shown in Figures 1 to 4, the fastening self-locking adjustable nut of the utility model welding is welded stamping 2 by the self-locking nut body 1 of cold-heading molding form with stamping forming, and the self-locking nut body 1 of cold-heading molding is fastened in stamping forming welding stamping 2;
The self-locking nut body 1 of cold-heading molding comprises self-locking nut housing 11, self-locking thread 12, cubic flange body 13, and self-locking nut housing 11 is fixed with cubic flange body 13, and self-locking thread 12 is positioned at self-locking nut housing 11.
Stamping forming welding stamping 2 comprises face of weld 21, spacing leg 22, the centre of face of weld 21 is provided with a cubic penetration hole 23, the diameter of four directions penetration hole 23 is greater than the diameter of self-locking thread 12, four angles of face of weld 21 are respectively equipped with four circular weld salient points, 24, two spacing legs 22 and form an oval breach 25.
The space that four directions penetration hole is installed for providing adjustment, displacement interval when namely screwing in for bolt adjusts automatically.Circular weld salient point makes not mate with butt-welding fitting material due to welded nut without the need to considering in welding procedure, reduces the technical requirements to welding.
The external shape of self-locking nut housing is circular or polygonal.One end of self-locking thread reaches rigidity auto-lock function by external compression distortion.The other end of self-locking thread is provided with the counterbore 14 that is greater than self-locking thread external diameter, and counterbore is used for when bolt is pre-installed placed in the middle fast, and perpendicular fastener, prevent from locking inclined, thread biting locking phenomenon.The self-locking nut body of cold-heading molding has automatic calibration hole and rigidity auto-lock function.The welding stamping that four directions flange body is stamped shaping is formed spacing, prevents bolt from screwing in when installing and produces rotation.
As shown in Figure 5, the circular weld salient point of stamping forming welding stamping 2 welds with soldered sheet metal part 3, and bolt 5 is connected with the self-locking thread of the self-locking nut body 1 of cold-heading molding, and fastened sheet metal part 4 is between bolt 5 and soldered sheet metal part 3.
Above-described specific embodiment; the technical problem of solution of the present utility model, technological scheme and beneficial effect are further described; be understood that; the foregoing is only specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any amendment made, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
