Description

A kind of self-plugging rivet

Technical field

The utility model belongs to field of machining, particularly a kind of self-plugging rivet.

Background technique

The applicable interlayer scope of traditional self-plugging rivet is only 1mm, and after installation, core bar fracture size and matrix tolerance range are at 0~2.6 ㎜, and the core bar fracture that needs to polish after installation makes it smooth, so inefficiency.If while installing for small space, because core bar fracture dimensional range is large, cause situations such as often occurring breaking end, crossing riveting in installation process; In bruting process, damage is also easily caused in the rivet nut surface in addition, rivet nut is threaded with core bar and occurs becoming flexible, installation quality is difficult to be controlled.

The model utility content

For overcoming above-mentioned defect, the technical problems to be solved in the utility model is to provide a kind of easy to operate and the fracture size is little, the self-plugging rivet of the core bar fracture that do not need to polish.

A kind of self-plugging rivet, this rivet comprises rivet nut, core bar, drive nut, body, ring; Rivet nut between body and drive nut, rivet nut with core bar for being threaded; Core bar bar footpath is Full Thread FT, and the one end is T shape round column structure, at the middle part of core bar, is provided with and twists into two parts groove, twists into two parts two sections, groove two ends Major Diam inconsistent, by the head end Major Diam, is greater than by the tail end Major Diam; Body is complete hollow step hole cylindrical structural, with core bar be Spielpassung, be set in core bar; Ring is full hollow cylinder structure, with body be Spielpassung, be installed in the relevant position of body; The end that rivet nut matches with body is external conical shape, and another end that matches with drive nut is for inner conical, and whole rivet nut is complete hollow female thread structure; Drive nut is the hexagonal female thread structure, and with core bar, for being threaded, the large footpath of drive nut internal thread size is consistent with core bar tail end Major Diam; The end that drive nut matches with rivet nut is also cone structure.

The utility model self-plugging rivet has that intensity is high, riveting is reliable, easy to operate, installation efficiency high.

The accompanying drawing explanation

The mounting structure schematic diagram that Fig. 1 is the utility model self-plugging rivet.

Embodiment

Use at present a large amount of self-plugging rivet on clamp connector, because there is defect in traditional self-plugging rivet, the technician has developed a kind of novel high-strength by practice for many years and has connected self-plugging rivet, and this rivet riveting gun in the riveted joint installation process drives the drive nut rotation and causes the body distortion to form one " large footing " shape on matrix to reach the effect of riveted joint pretension.

As shown in Figure 1, a kind of novel high-strength connects self-plugging rivet, and this rivet comprises rivet nut 1, core bar 2, drive nut 3, body 4, ring 5.Rivet nut 1 between body 4 and drive nut 3, rivet nut 1 with core bar 2 for being threaded; Core bar 2 bar footpaths are Full Thread FT, and the one end is T shape round column structure, at the middle part of core bar 2, is provided with and twists into two parts groove, twist into two parts two sections, groove two ends Major Diam inconsistent, by core bar head end Major Diam, are greater than by the tail end Major Diam; Body 4 is complete hollow step hole cylindrical structural, with core bar 2 be Spielpassung, be set on core bar 2.Ring 5 is the full hollow cylinder structure of plastic material, with body 4 be Spielpassung, be installed in the relevant position of body 4; The end that rivet nut 1 matches with body 4 is external conical shape, and another end that matches with drive nut 3 is for inner conical, and whole rivet nut 1 is complete hollow female thread structure; Drive nut 3 is the hexagonal female thread structure, and with core bar 2, for being threaded, the large footpath of drive nut internal thread size is consistent with core bar tail end Major Diam.The end that drive nut 3 matches with rivet nut 1 is also cone structure.

During operation, riveting gun drives core bar 2 rotations, drives drive nut 3 rotations simultaneously, till being screwed to drive nut 3 and being adjacent to rivet nut 1.Because rotation makes body 4 distortion, riveting is revolved when contact with drive nut in core bar 2 fault trough places, because the core bar Major Diam is greater than the large footpath of drive nut, core bar no longer rotate driven nut from fault trough twist revolve disconnected, thereby reach the pretension effect, assurance riveting intensity.

The utility model adopts advanced drive nut 3 blocking-up principles, applicable interlayer scope 1.27mm, and riveted joint core bar fracture dimensional range, at 0~0.76 ㎜, has guaranteed that core bar fracture size and matrix plane are basically identical.Guarantee that from fracture size and moulding blocking-up principle core bar not there will be the phenomenons such as riveting, broken end, in addition because the core bar fracture is of a size of 0~0.76, do not improved efficiency thereby do not need to install rear polishing, guaranteed that the rivet nut surface can not sustain damage, and has improved the installation quality of self-plugging rivet yet simultaneously.The utility model is specially adapted to the riveted joint of single face bindiny mechanism.
