Description

Threaded self-plugging rivet rivet

Technical field

The utility model relates to a kind of machine components technical fields, relate in particular to a kind of threaded self-plugging rivet rivet.

Background technique

Rivet is a kind of common securing member, is widely used, and threaded self-plugging rivet rivet abbreviation threaded self-plugging rivet, is in rivet A major class, belong to high End rivet, be mainly used in aerospace and ship domain.

Currently, existing threaded self-plugging rivet rivet is high shearing resistance rivet and big bottom threaded self-plugging rivet, plush copper type is divided into (see figure And countersunk head type (see figure 2) two major classes 1).Wherein, high shearing resistance rivet (or is lining by core bar, the shaft of rivet (or cry nail cover) and ring Set) three parts composition, in use, assembled threaded self-plugging rivet rivet component to be first inserted into rivet hole prefabricated on interlayer, in riveting Under the action of rifle, two symmetrical flat and a disconnected diameter slot threaded core bars rotations are set, the shaft of rivet of high shearing resistance rivet (or Make nail cover) or the nail set (or being the shaft of rivet) and twisting nut of big bottom threaded self-plugging rivet remain stationary, under the action of screw thread, core Club head moves closer to interlayer along core bar axial movement, squeezes ring (or being bushing) and makes its deformation, ring (or being bushing) It is broken from disconnected diameter slot after deformation with the shaft of rivet (or nail is made to cover) collective effect, locking interlayer, core bar, achievees the purpose that connection. The component part quantity of above-mentioned threaded self-plugging rivet is more, and structure is more complex, and processing efficiency is lower.

Summary of the invention

The component part provided the purpose of the utility model is to overcome disadvantages mentioned above is few, and structure is simple, easy to use Efficiently threaded self-plugging rivet rivet.

It the utility model aim and solves its technical problem underlying and adopts the following technical solutions to realize:

A kind of threaded self-plugging rivet rivet of the utility model, including core bar and the shaft of rivet, in which: the shape of core bar is that sequence is set Pin head, step, external screw thread, disconnected diameter slot, two symmetrical flat straight-bars are equipped with, the shape of the shaft of rivet is the sequence setting shaft of rivet Head, bar portion, bar portion tail end are provided with softened zone, and the shaft of rivet is equipped with internal thread hole and stepped hole, the internal screw thread and core bar of the shaft of rivet External screw thread connection.

Above-mentioned threaded self-plugging rivet rivet, in which: shaft of rivet head is plush copper or taper.

Above-mentioned threaded self-plugging rivet rivet, in which: softened zone is that stepped hole is softened close to internal thread hole part, tail portion 1mm or so does not soften.

The utility model compared with prior art, has apparent beneficial effect, as can be known from the above technical solutions: this is practical Novel to be only made of core bar and nail set, core bar is attached with nail set by screw thread, and structure is simple, convenient to use, assembling Prefabricated rivet hole on good threaded self-plugging rivet rivet component insertion interlayer, under the action of riveting gun, setting two is flat and one disconnected Diameter slot, step are rotated with externally threaded core bar, be arranged a stepped hole with internal thread hole and through the nail of local softening Set remains stationary, and under the action of screw thread, core bar head moves closer to interlayer along core bar axial movement, squeezes nail pressing sleeve and makes its warp The part of local softening deforms, and when core bar is axially moveable a predetermined distance, nail set deformation is reached a certain level, is set to Step end face on core bar is in contact with the inner face for being set to nail and putting on stepped hole, and torque increases suddenly, and core bar is from disconnected diameter It is broken at slot, riveting process is completed.Nail covers and makes it after the deformation of the part of local softening and nail set head collective effect, locking Interlayer realizes riveting.

Specific embodiment

Below in conjunction with attached drawing and preferred embodiment, to according to the utility model proposes threaded self-plugging rivet rivet specific implementation Mode, structure, feature and its effect, detailed description is as follows.

As shown in fig. 3 to 7, a kind of threaded self-plugging rivet rivet, including core bar 1 and the shaft of rivet 2, in which: the shape of core bar 1 is suitable Sequence is provided with pin head 4, step 5, external screw thread 6, disconnected diameter slot 7, symmetrical two flat 8 straight-bars, and the shape of the shaft of rivet 2 is sequence It is softened zone 11 that shaft of rivet head 9, bar portion 10, bar portion tail end, which is arranged, and the shaft of rivet 2 is equipped with band internal thread hole 12 and stepped hole 13, core The external screw thread of bar 1 is connect with the internal screw thread of the shaft of rivet 2.2 head of the shaft of rivet is plush copper or taper.Softened zone 11 is that stepped hole 13 leans on Nearly 12 part of internal thread hole is softened, and tail portion 1mm or so does not soften.

According to the use occasion of threaded self-plugging rivet, is separately designed and be fabricated to plush copper type threaded self-plugging rivet (see figure 3) and sunk Head dummy threaded self-plugging rivet (see figure 4).The threaded self-plugging rivet core pin shaped of two kinds of head dummys be it is identical, be distinguished as nail set head locating for position It sets different with rotation stop mode.The head that specially plush copper type threaded self-plugging rivet follows closely set when in use is fully exposed to outside interlayer, only Turning mode is the flat of different number, and when flat quantity is six, i.e., head is hexagonal head type；Countersunk head type threaded self-plugging rivet is when in use It designs and the nail set head for being fabricated to taper is sunk to completely inside interlayer counter sink, rotation stop mode is cross recess.Two kinds of head dummys The shaft of rivet 2 of threaded self-plugging rivet is respectively provided with internal thread hole 12 and stepped hole 13, and close to the internal thread hole 12 of head end, tail end is step Hole 13, stepped hole 13 are softened close to 12 part of internal thread hole, and tail portion 1mm or so does not soften, and the length of core bar step 5 is less than The difference of the depth of 2 stepped hole 13 of the shaft of rivet, the two is determined according to the size of bulge after riveting, small if you need to bulge, then the two is poor Value answer it is small, anyway, also greatly；The diameter of core bar step 5 is slightly less than 2 stepped hole of the shaft of rivet, 13 diameter, cooperates for small―gap suture；Core bar 1 The internal screw thread of external screw thread and the shaft of rivet 2 match, be clearance fit.

The above descriptions are merely preferred embodiments of the present invention, not makees in any form to the utility model Limitation, it is any without departing from the content of the technical scheme of the utility model, according to the technical essence of the utility model to above embodiments Made any simple modification, equivalent change and modification, are still within the scope of the technical solutions of the present invention.
