Abstract
The utility model discloses a kind of self-plugging rivet, including core bar, head and body, head is arranged on the right-hand member of core bar, cut-off neck slot it is provided with on core bar, body noose is on core bar, on described core bar, head is provided with flange collar, on described body, one end away from flange collar is provided with the head of a nail of taper, annealing portion it is provided with in the middle part of body, also including pushing lining and the lock ring of band endoporus, the endoporus pushing lining is provided with dogging shoulder, pushes lining noose on core bar, lock ring noose is on core bar, and lock ring is arranged at the dogging shoulder pushing lining.This utility model simple in construction, installs convenient to operation, highly versatile, installation process and the least to the damage of connected piece after installing, and arranges flange collar, can rivet the connected piece of different-thickness, can be with the bigger thickness of interlayer of the scope of application；Arranging pushing lining and lock ring, add the intensity of structure, be unlikely to deform, riveting effect is more preferable.
Description
Technical field
This utility model relates to a kind of rivet, particularly to a kind of self-plugging rivet.
Background technology
In Aeronautics and Astronautics aircraft, more strict owing to own wt is controlled, often occur that installing space is narrow and small, the situation that workman cannot successfully install.In this case, the self-plugging rivet that can be used to blind riveting installation is generally used to realize assembling.Self-plugging rivet have lightweight, connect more reliable, intensity is high, the feature such as quick and easy for installation, all kinds of aerospace vehicles are widely applied.In view of the safety of Aeronautics and Astronautics aircraft, the performances such as the tension of self-plugging rivet, shearing resistance, pretightning force, locking there is the highest requirement；Meanwhile, the planarization twisting off groove port also there is higher requirement.Existing self-plugging rivet is combined by three to five bulk-breakings, structure is complex, owing to bulk-breaking is more, in self-plugging rivet installation process, easily produce axially loaded the situation of deviation occurs, cause installation process eccentricity excessive, cause installing built on the sand, twist off the bad phenomenon such as groove port out-of-flatness, even damage parts.
Utility model content
The purpose of this utility model is that a kind of simple in construction of offer, installs firm, rivets effective self-plugging rivet.
To achieve these goals, the technical solution adopted in the utility model is such that self-plugging rivet of the present utility model, including core bar, head and body, head is arranged on the right-hand member of core bar, cut-off neck slot it is provided with on core bar, body noose is on core bar, on described core bar, head is provided with flange collar, on described body, one end away from flange collar is provided with the head of a nail of taper, annealing portion it is provided with in the middle part of body, also include pushing lining and the lock ring of band endoporus, the endoporus pushing lining is provided with dogging shoulder, push lining noose on core bar, lock ring noose is on core bar, and lock ring is arranged at the dogging shoulder pushing lining.
As preferably, described flange collar is three, and three flange collar intervals are arranged.
As preferably, the left part of described core bar is provided with clamping face.
Compared with prior art, the utility model has the advantage of: this utility model simple in construction, install convenient to operation, highly versatile, installation process and install after the least to the damage of connected piece, flange collar is set, the connected piece of different-thickness can be riveted, can be with the bigger thickness of interlayer of the scope of application；Arranging pushing lining and lock ring, add the intensity of structure, be unlikely to deform, riveting effect is more preferable；Installation process uses screw drive, it is to avoid axially loaded occurs deviation to cause installation process eccentricity excessive, improves installation accuracy and the reliability of installation, concordance；Fix without lock ring after installation, firm fixing by threaded engagement, only deposit three bulk-breakings, improve product anti-loosening property and dependability；Block cut-off neck slot by actuator, block efficiency height, planarization and concordance high.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
See Fig. 1, self-plugging rivet of the present utility model, including core bar 1, head 2 and body 4, head 2 is arranged on the right-hand member of core bar 1, cut-off neck slot 5 it is provided with on core bar 1, body 4 noose is on core bar 1, on described core bar 1, head 2 is provided with flange collar 3, on described body 4, one end away from flange collar 3 is provided with the head of a nail 7 of taper, annealing portion 9 it is provided with in the middle part of body 4, also include pushing lining 6 and the lock ring 8 of band endoporus, the endoporus pushing lining 6 is provided with dogging shoulder, push lining 6 noose on core bar 1, lock ring 8 noose is on core bar 1, and lock ring 8 is arranged at the dogging shoulder pushing lining 6, described flange collar 3 is three, three flange collar 3 intervals are arranged, the left part of described core bar 1 is provided with clamping face 10.
Flange collar 3 is set on core bar 1, the connected piece of different-thickness can be riveted, can be with the bigger thickness of interlayer of the scope of application；Arranging pushing lining 6 and lock ring 8, add the intensity of structure, be unlikely to deform, riveting effect is more preferable；Installation process uses screw drive, it is to avoid axially loaded occurs deviation to cause installation process eccentricity excessive, improves installation accuracy and the reliability of installation, concordance；Fix without lock ring 8 after installation, firm fixing by threaded engagement, only deposit three bulk-breakings, improve product anti-loosening property and dependability；Block cut-off neck slot 5 by actuator, block efficiency height, planarization and concordance high；This utility model simple in construction, installs convenient to operation, highly versatile, the least to the damage of connected piece after installation process and installation.
