Embodiment
The utility model is further elucidated with reference to the accompanying drawings and examples.
A kind of locking riveted nut, as depicted in figs. 1 and 2, including nut body 1, nut body 1 open up inner bolt hole 11,
Nut body 1 is provided with binding face 12, and binding face 12 is provided with mosaics, the height h of mosaics (i.e. upper surface 13 and binding face 12
Distance) be equal to the thickness of sheet material 2, sheet material 2 is cubic as shown in figure 3, the inlaid hole of sheet material 2 includes the gridle 21 of square
The corner of gridle 21 of shape is provided with circular arc chamfering side 22, and four circular arc chamfering sides 22 are concentric.The corner of mosaics is provided with riveting mouthful
Salient point 14, two parallel gridles 21 of inlaid hole it is equal with the width b of mosaics apart from B, two diagonal circular arcs fall
A kind of form of presentation, namely riveting mouthful salient point (are changed in riveting mouthful salient point 14 outer surfaces diagonal equal to two apart from A of the arm of angle 22 apart from a
14 external diameter is equal to the internal diameter on circular arc chamfering side 22, is the dimensional tolerance for ignoring hole cooperation here certainly).Mosaics is with inlaying
Hole coordinates, because in square, four sides of mosaics constitute non slip surface 15, and nut body 1 is will not to be rotated around axle center
, serve skidproof effect.During riveted, riveting mouthful salient point 14, which turns up, to be pressed together on the upper surface of sheet material 2, four angles of binding face 12
Locking salient point under composition, riveting mouthful salient point 14 constitutes upper locking salient point, and locking salient point and upper locking salient point clamp sheet material 2 under
(as shown in Figure 5 and Figure 6).
Riveted for convenience, the inner surface 141 of the riveting mouthful salient point 14 is inclined-plane.As shown in figure 4, during riveted,
The bottom of the groove fixing nut body 1 of lower mould 3, the mosaics of nut body 1 passes through the gridle 21 of sheet material 2, and upper mould 4 is pushed
Make the riveting mouthful outer retreading forming of salient point 14, four angles and riveting mouthful salient point 14 for making binding face 12 clamp sheet material 2, nut can be limited simultaneously and existed
Radially, axially 6 frees degree after assembling, it is ensured that the intensity after nut assembling.
With the locking riveted nut of the present embodiment and common cold-reduced sheet riveted, progress agrees with strength failure experiment, sheet material
Thickness is 1.5mm.The peak of curve of pull-out force trial curve is 5.095 thousand Ns；The peak of curve of pressure-off power trial curve is
3.275 thousand Ns, (with reference to MES CH 401D welded nut crushing forces standard).Torsional test intensity 5674kgfcm can be carried
(normative reference MES CH 400E).
Relative to general point project-welding nut, the utility model effectively prevent electric current, voltage, air pressure, temperature during because of welding
It is too high or cross bottom and cause fusion penetration deviation after nut-welding, and the weld strength that human factor is caused is unqualified.
Embodiment 2
During long-time use, nut stress, when riveting mouthful salient point 14 is relatively thin, the riveting mouthful stress of salient point 14 can deform bullet
Rise, can become riveted effect, may loosen；When riveting mouthful salient point 14 is thicker, it is necessary to which big stamping press can just make riveting mouthful salient point 14
Bending, and bend that effect is poor, effect of being fitted with sheet material 2 is poor.In order that obtaining riveting mouthful salient point 14 both easily bends glued board 2
(being not required to blocked up), is close to sheet material 2 all the time, and deformation is not upspring and loosened in use, and the utility model is devised such as Fig. 7
With the locking riveted nut shown in Fig. 8, including nut body 1, nut body 1 opens up inner bolt hole 11, and nut body 1 is provided with laminating
Face 12, binding face 12 is provided with mosaics, and the height h of mosaics is equal to the thickness of sheet material 2, and the inlaid hole of sheet material 2 includes four directions
The gridle 21 of shape, the corner of gridle 21 of square is provided with circular arc chamfering side 22, and four circular arc chamfering sides 22 are concentric.Inlay
The corner of body is provided with riveting mouthful salient point 14, and the inner surface 141 of the riveting mouthful salient point 14 is inclined-plane, two parallel edges of inlaid hole
, the external diameter internal diameter equal to circular arc chamfering side 22 of riveting mouthful salient point 14 equal with the width b of mosaics apart from B of panel 21.Inlay
Body coordinates with inlaid hole, because in square, nut body 1 will not rotate around axle center, serve skidproof effect.Mosaics
Four pressing plates 16 of upper setting, pressing plate 16 is arranged on the inner side of riveting mouthful salient point 14, preferably curved, the circle of four pressing plates 16 of pressing plate 16
With one heart, the inner surface 161 of pressing plate 16 is inclined-plane to arc, and the height of pressing plate 16 is higher than riveting mouthful salient point 14, and locking riveted nut is also wrapped
Elastic washer is included, after riveting mouthful salient point 14 is pressed, elastic washer 17 as shown in Figure 9 and Figure 10, four pressures are padded on riveting mouthful salient point 14
The bending of plate 16 compresses elastic washer 17.The riveted nut of this structure, elastic washer 17 has elastic force, makes riveting mouthful convex by elastic force
Point 14 is by the power to sheet material 2, so that riveting mouthful salient point 14 will not upspring, riveted is more firm.Most preferably pressing plate 16 compares
Riveting mouthful salient point 14 is slightly thick, and more preferably, pressing plate 16 will not more be deformed stress.
Elastic washer 17 as shown in Figure 9 and Figure 10, is made of the metal material of elasticity and good toughness, including upper annulus
171 and lower circular arc 172, the inner edge arc transition connection of both upper annulus 171 and lower circular arc 172, upper annulus 171 and lower circular arc
172 be integrally formed, and upper annulus 171 and lower circular arc 172 possess certain elastic force, after upper annulus 171 and lower circular arc 172 are pressurized
Elastic force with reset.Elastic washer 17 can also be using spring leaf or the annular component of other flexible power.
In order that must press more firm, the outer surface top of 12 4 jiaos of binding face and riveting mouthful salient point 14 annular knurl or can be set
Convex thorn is put, sheet material 2 can be suitably pressed into, skidproof effect is more preferable.
During riveted, the bottom of the groove fixing nut body 1 of lower mould, mosaics the inlaying through sheet material 2 of nut body 1
Side 21, the protection core for preventing that pressing plate 16 from bending inwards is placed four inner sides of pressing plate 16, protection core is outer surface and pressing plate
The cylinder of 16 inner surfaces laminating, for prevent from pressing mouthful salient point 14 when, pressing plate 16 is deformed, and can protect riveting mouthful salient point pressing mold
Pressure head.Riveting mouthful salient point pressing mold pushes mouthful salient point 14 that makes to press and bent, and four angles and riveting mouthful salient point 14 for making binding face 12 are clamped
Sheet material 2, then removal riveting mouthful salient point pressing mold and protection core, elastic washer 17 are enclosed on outside pressing plate 16, using pressing plate stamping die
Pressing plate 16 is bent, makes pressing plate 16 that elastic washer 17 is pressed on riveting mouthful salient point 14.
Locking riveted nut of the present utility model, riveted firmly, will not loosen, convex by the elastic washer mouth that presses
Point, lasting stability is good.
