Description
Technical field
The present invention relates to a kind of rivet, be specifically used for riveting the collapsible shockproof rivet of titanium alloy of the specific uses such as aircraft, astrovehicle.
Background technique
At present, mostly product in the specific uses such as riveted joint aircraft, astrovehicle is to rivet with common Lantern Type Rivet and two drum type rivet, self material and structural narrow limitation due to these two kinds of rivets, after product riveted joint, encounter special dimension and have the corrosion-prone defect of appearance, thereby damage by riveting products, affect product quality and performances.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of titanium alloy collapsible shockproof rivet, it is simple and reasonable, cydariform foot expands during staking, be connected firmly, sealability and shockproof properties are high, and intensity is high, corrosion-resistant, toughness sufficient, ductility is strong.
According to technological scheme provided by the invention: the collapsible shockproof rivet of titanium alloy, comprise rivet nut and blind rivet, it is characterized in that: the tubular body that described rivet nut is boring, described blind rivet one end is processed with ailhead, and the blind rivet the other end penetrates in rivet nut and from rivet nut head and stretches out from rivet nut tail end; Described rivet nut comprises rivet nut body and the rivet nut head being wholely set, the external diameter of rivet nut head is greater than the external diameter of rivet nut body, on the outer wall of rivet nut body, be provided with circumferentially uniform longitudinal groove of at least two edges, described longitudinal groove extends to the rivet nut the other end from the lower surface of rivet nut head, and leave distance with the end of the rivet nut the other end, the equal in length and two ends of described at least two longitudinal grooves are concordant.
As a further improvement on the present invention, in the lower surface of described rivet nut head, sealed nylon circle is housed.
As a further improvement on the present invention, the lower surface of described rivet nut head is provided with shallow annular groove along the circumferential direction, and described sealed nylon circle is contained in shallow annular groove, and sealed nylon circle protrudes outside shallow annular groove.
As a further improvement on the present invention, described longitudinal groove has three.
As a further improvement on the present invention, described rivet nut adopts titanium alloy material to make.
the present invention compared with prior art, has the following advantages:
(1) owing to being provided with in rivet nut of the present invention on the outer wall of body, be provided with some longitudinal grooves, during riveted joint workpiece, rivet nut is lower outside the drawing of effect of riveting gun, thereby make the bending of outwards expanding of strip rivet nut wall between adjacent two longitudinal grooves, several uniform petal kinks have been formed, the cydariform that expands during staking is sufficient, has solved a difficult problem for cydariform deficiency after riveted joint; And riveting operation is simple and convenient, operating noise is low.
(2) the ailhead inner side surface circumferencial direction due to rivet nut of the present invention has shallow annular groove, and sealed nylon circle is installed in shallow annular groove, and after riveted joint, seal ring is in ailhead and between by riveting piece, and sealability and shockproof properties improve greatly.
(3), because rivet nut of the present invention adopts titanium alloy material, make, the advantage such as have that intensity is high, corrosion-resistant, toughness foot, ductility are strong, can avoid the adverse consequences being corroded under particular surroundings after rivet.

Embodiment
Below in conjunction with concrete drawings and Examples, the invention will be further described.
As shown in Fig. 1 ~ Fig. 3: the collapsible shockproof rivet of titanium alloy in embodiment is mainly comprised of rivet nut 1 and blind rivet 2; The tubular body that described rivet nut 1 is boring, described blind rivet 2 can adopt conventional blind rivet 2, and blind rivet 2 one end are processed with ailhead 2a, and blind rivet 2 the other ends penetrate in rivet nut 1 and stretch out from rivet nut head 1b from rivet nut 1 tail end; Described rivet nut 1 comprises rivet nut body 1a and the rivet nut head 1b being wholely set, the external diameter of rivet nut head 1b is greater than the external diameter of rivet nut body 1a, on the outer wall of rivet nut body 1a, be provided with circumferentially uniform longitudinal groove 1c of three edges, described longitudinal groove 1c extends to rivet nut 1 the other end from the lower surface of rivet nut head 1b, and leave distance with the end of rivet nut 1 the other end, the equal in length and two ends of described three longitudinal groove 1c are concordant.
As shown in Figure 1 and Figure 2, in the embodiment of the present invention, described rivet nut head 1b is annular solid, and the top surface of rivet nut head 1b is sphere, and the lower surface of rivet nut head 1b is plane.
As shown in Figure 1 and Figure 2, in the embodiment of the present invention, in the lower surface of described rivet nut head 1b, sealed nylon circle 3 is housed, to improve the shockproof properties after riveted joint.In order to prevent that sealed nylon circle 3 from moving in riveted joint process, the lower surface of described rivet nut head 1b is provided with shallow annular groove 1d along the circumferential direction, described sealed nylon circle 3 is contained in shallow annular groove 1d, and sealed nylon circle 3 protrudes outside shallow annular groove 1d.
In the present invention, described rivet nut 1 preferably adopts titanium alloy material to make, and has the advantages such as intensity is high, corrosion-resistant, toughness sufficient, ductility is strong, can avoid the adverse consequences being corroded under particular surroundings after rivet.
In concrete application, while adopting the present invention to rivet workpiece 4, first rivet nut 1 and blind rivet 2 are fitted together to (shown in Fig. 1), then insert in the hole of beating in advance on workpiece 4 (shown in Fig. 4), with riveting gun, blind rivet 2 is pulled outwardly again, make the bending of outwards expanding of strip rivet nut 1 wall between the longitudinal groove 1c of rivet nut body 1a upper adjacent two, until formed shown in three uniform petal kink 5(Fig. 5, Fig. 6 by riveting piece 4 inner sides), thus make to be clamped between three petal kinks 5 and rivet nut head 1b by riveting piece 4.And because the sealed nylon circle 3 in rivet nut head 1b lower surface is clamped at rivet nut head 1b and is riveted between workpiece 4 after riveted joint, nylon material good springiness, can shockproofly can seal again.
After the collapsible shockproof rivet of titanium alloy of the present invention is connected on aircraft, astrovehicle part, can keep that rivet nut 1 is not rotated, blind rivet 2 does not come off, water, shock, firmly, noise is low in anti-anticorrosive strong, riveted joint.
