Abstract
The invention discloses a kind of expansion sleeve type rivets.It includes the head of tapered sleeve structure and reaches bar portion outside head, it is provided with to compress the flange of riveting parts in the middle part of head, the groove arranged along tapered sleeve surface is provided on the circumference on head, one section that head is stretched into bar portion is provided with baffle ring, baffle ring makes tapered sleeve inner cavity be formed to place the cavity of extruded material, extruded material is placed in cavity, rivet can make extruded material squeeze out the inner surface for being pressed on workpiece in staking deformation process.After above-mentioned structure, it can make through tapered sleeve /V in work piece inner surface in staking deformation process, at the same time, extruded material is also pressed on work piece inner surface by squeezing, it is made to be completely combined to form an entirety with workpiece, thereby produces powerful tightening force, two workpiece is made only to tense together, it will not reduce due to the extension of time and rivet tightly power, tense good reliability, ensure that permanent use.
Description
Technical field
The present invention relates to a kind of rivet, specifically a kind of expansion sleeve type rivet.
Background technology
Rivet is the common components for two components are anchored, and existing rivet generally all includes bar portion and head
Portion in use, first accomplishing fluently mounting hole with boring bar tool, pulling rivet is then placed in mounting hole, is finally acted on again with hand riveter
It in rivet, firmly deforms the staking of rivet, disc is formed after rivet deformation expansion sleeve type or cylindrical chuck is stuck in mounting hole
In, staking connection is completed, the rivet of existing this structure can be such that two workpiece only tense together, but of long duration
Easily make to rivet tightly power reduction, loosened so as to generate, affect use.
The content of the invention
It rivets tightly that power is big the technical problem to be solved in the present invention is to provide one kind, is not likely to produce the expansion sleeve type rivet of loosening.
In order to solve the above-mentioned technical problem, expansion sleeve type rivet of the invention, head including tapered sleeve structure and reaches
Bar portion outside head is provided with to compress the flange of riveting parts in the middle part of head, is provided on the circumference on head along tapered sleeve surface
The groove of arrangement, one section that head is stretched into bar portion are provided with baffle ring, and baffle ring makes tapered sleeve inner cavity be formed to place extrusion molding material
The cavity of material, cavity is interior to place extruded material, and rivet can make extruded material extrusion be pressed on workpiece in staking deformation process
Inner surface.
The outer surface of the tapered sleeve is provided with undulatory protrusion.
The outer surface of the tapered sleeve is provided with the protrusion of odontoid.
The groove sets at least to two rows.
After above-mentioned structure, due to being provided on the head of tapered sleeve structure of setting and the circumference on head along tapered sleeve table
The groove of face arrangement, forms the cavity for placing extruded material in tapered sleeve, can make to limit by tapered sleeve in staking deformation process
Position is in work piece inner surface, and at the same time, extruded material is also pressed on work piece inner surface by squeezing, it is made to be completely combined with workpiece
An entirety is formed, powerful tightening force is thereby produced, two workpiece is made only to tense together, it will not be because of the extension of time
And reduce and rivet tightly power, good reliability is tensed, ensure that permanent use.
Description of the drawings
Fig. 1 is the structure diagram of expansion sleeve type rivet of the present invention.
Specific embodiment
With reference to the accompanying drawings and detailed description, the expansion sleeve type rivet of the present invention is described in further detail.
As shown in the figure, the expansion sleeve type rivet of the present invention, head 1 including tapered sleeve structure and the bar portion to outside head is foiled
2, outside head, the middle part on head 1 is provided with to compress the flange 3 of riveting parts, the circumference on head 1 for the end /V of bar portion 2
On be provided with the groove 4 arranged along tapered sleeve surface, one section that head is stretched into bar portion 2 is provided with baffle ring 5, and baffle ring 5 makes in tapered sleeve
Chamber forms to place the cavity of extruded material, places extruded material 6 in cavity, rivet can make to squeeze in staking deformation process
Moulding material squeezes out the inner surface for being pressed on workpiece.
Wherein, the outer surface of described tapered sleeve can both be provided with undulatory protrusion, can also be provided with odontoid
Protrusion, thus further improves pressing force in staking deformation process, and groove 4 sets at least to two rows, wherein groove 4
The reduced diameter section of tapered sleeve is arranged on, thus enables that the pressing force of upper and lower both sides keeps balance, further improves tightening force.
