What is the tolerance range of precision screws?
Therefore, how to provide a socket nut, a fastener and an installation method thereof that are more firmly connected and can be applied to thin-walled profiles is a technical problem to be solved by those skilled in the art.
Generally speaking, the metal plate needs to open holes for inserting the rivets, and then press the two sides of the metal plate along the positive direction of the metal plate with a jig, so that the metal plate is deformed in the plane direction, which makes the inner edge of the hole Shrink and fit the rivet. Existing riveting techniques are not suitable for thin sheets. Because the thin plate does not have enough thickness to compress in its forward direction, the insufficient deformation in the forward direction causes enough deformation in the plane direction to insert the rivet, so the rivet cannot be firmly fixed to the thin plate.
Yueluo Company adopts the following technical solutions: fasteners for preventing nuts from falling off, including bolts and nuts, the nuts are provided with screw holes, the screw holes are provided with internal threads, the bolts are provided with M grooves along its axial direction, M ≥1; There is an arc-shaped notch on the screw hole of the nut, and there are N V-shaped tooth grooves along the axial direction of the nut in the arc-shaped notch, N≥2; a locking strip is placed in the groove, and the locking The bar includes a locking bar body and a V-shaped locking tooth, the width of the locking bar body is the same as the width of the groove, the V-shaped locking tooth is located on one side of the locking bar body, and the V-shaped locking tooth is engaged with the V-shaped locking tooth.
Yueluo also provides a thin plate rivet structure, which includes a metal thin plate and a rivet. The metal sheet is provided with a riveting hole; the riveting piece is penetrated in the riveting hole, the outer edge of the riveting piece is provided with an occlusal structure, and the inner edge of the riveting hole is embedded with the occlusal structure. A deformation groove is provided on the metal sheet, and the deformation groove is adjacent to the rivet hole.
