Installation process：
The small blind die screw thread core pulling rivet of one kind is inserted in matrix hole to be connected.Clamp core bar tail respectively with riveting gun
The symmetrically arranged concave plane 15 in portion and drive nut 4, make drive nut 4 be relatively rotated relative to core bar 1, drive nut
4 move under the interlocking of driving screw thread and the thread segment 14 of core bar 1 second to the direction of head convex body 11 of core bar 1, now, drive
Dynamic nut 4 makes rivet nut 3 not turned round relatively with drive nut 4 by the mating reaction between striped 41 and the groove of rivet nut 3 35
Turn, but drive nut 4 applies the power in the direction of head convex body 11 towards core bar 1 to rivet nut 3 simultaneously, and rivet nut 3 passes through rivet nut tail cone
Portion 31 applies the power being subject to body 2, and rivet nut boattail 31 creeps into the first through hole of body 2 section 22 first, and body 2 is in rivet nut tail
It is softened under the bi-directional force of tapering 31 and the head convex body 11 of core bar 1, rivet nut boattail 31 progresses into the through hole of body 2 second
Section 21, the first through hole section 22 of the now entrance of rivet nut sheath body portion 33 body 2；Until rivet nut boattail 31 goes to the head of core bar 1
At convex body 11, body 2 is strutted completely, and rivet nut boattail 31 is engaged with the second through hole section 21 of body 2, rivet nut sheath body portion 33
It is engaged with body first through hole section 22, first through hole 22 ends of section of body 2 and the side of connected piece are brought into close contact, body
2 21 ends of the second through hole section are spacing by the head convex body 11 of core bar 1, and small blind die is integrally formed, the effect of fastening is reached.When
When drive nut 4 moves to core bar cut-off neck slot 13, process is moved on due to the first thread segment 12 and the spiral shell of the second thread segment 14
Line is differed, and the advance resistance increase that drive nut 4 is subject to, torsional moment enhancing so that cut-off neck slot 13 is blocked forms surface
The concordant plane of disruption, completes to install.
This self-plugging rivet is made up of core bar 1, body 2, rivet nut 3, drive nut 4, the screw thread core pulling rivet with other classes
Compare, the body 2 of the self-plugging rivet is a through-hole structure, and length is shorter, and diameter of bore is identical, without step, body 2 is provided with outer
The bigger first through hole section 22 in footpath and smaller the second through hole section 21 of external diameter, have chamfering 23 in first through hole 22 end endoporus of section；
Body 2 is set on core bar 1, and 21 ends of the second through hole section of body 2 are contacted with the head convex body 11 of core bar 1 and by the head
Convex body 11 is spacing.In riveting process, cecum forms small blind die rather than big base angle.Draw screw thread core pulling rivet pretightning force and antivibration
The big advantage of kinetic force, while eliminating big base angle, this is used for the factor of composite, saves the material of core bar 1 and body 2
Material, simplifies the manufacturing process of core bar 1 and body 2, improves installation quality, reaches the demand that economical and efficient one side is installed.Should
Used in cecum narrow space and be also easy to produce riveting interference metallic connection parts position.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
God is with principle, and any modification, equivalent substitution and improvements made etc. should be included in the scope of the protection.
