Description
Technical field
This utility model relates to a kind of riveting nut, especially relates to a kind of compound dismountable type step riveting nut.
Background technology
At present, riveting nut has been widely used for metal, nonmetallic plane, the riveting of non-planar junction component.With one
As riveting class securing member compare, riveting nut riveting after wherein another structure can freely dismantle, combine rivet and nut
Function, it is simple to keep in repair and update.Therefore in electronics industry, shipbuilding industry, automobile, motor-car manufacture also and aviation field etc. the most
Start extensively to use.
But, when existing riveting nut rivets for multiple riveting workpiece in different pre-holes, often by riveting bar
The restriction of part and occur riveting bad situation.
Utility model content
The purpose of this utility model is to provide one compound dismountable type step riveting nut, its can make riveting nut with
Different-thickness, riveting of pre-hole have good riveting effect equally between workpiece, and have more superior mechanical properties strength, with
Solve the problems referred to above existed when riveting nut in prior art rivets for multiple riveting workpiece in different pre-holes.
For reaching this purpose, this utility model by the following technical solutions:
One is combined dismountable type step riveting nut, and it includes riveting tube body, and the head end of described riveting tube body arranges oriented
Offering big stepped hole in the shade body of outer extension, and described riveting tube body, wherein, the bottom of described big stepped hole offers spiral shell
Pit, described riveting tube body is arranged with the liner collar selected according to the big freedom in minor affairs dismounting being riveted the pre-hole of workpiece.
Especially, the lateral wall of the described liner collar offers embedded anti-slop serrations.
Especially, the tail end of described riveting tube body is provided with the guide section that cross-sectional area tapers into.
Especially, the external diameter of riveting tube body described in the inner hole of the described liner collar is arranged.
The beneficial effects of the utility model are, the most described compound dismountable type step riveting nut is at riveting pipe
It is provided with the liner collar that can freely dismantle selection on body, under the conditions of solving different-thickness and pre-bore dia, rivets workpiece
Between riveting in occur unfavorable condition, compensate for common riveting nut to being riveted thickness of workpiece scope and the harshness of pre-hole size
Requirement；For the high rivet performance requirement under the conditions of the multiple pre-bore dia occurred between multiple riveting workpiece, also can produce very well
Effect.Riveting environment under the conditions of i.e. using a riveting nut just can solve different-thickness and multiple pre-bore dia, improves
Riveting nut, to being riveted the scope of application of workpiece, has saved client cost.The periphery of this liner collar is provided with embedding
Enter after formula anti-slop serrations has stopped product riveting and be riveted the possibility that on workpiece, skidding rotation phenomenon occurs, enhance riveting nut
And the combination effect being riveted between workpiece, is greatly improved the driving torque of riveting nut, it is therefore prevented that product is on riveting workpiece
The defect that easily skidding rotates, makes product shear behavior between riveting workpiece improve 3 times simultaneously, and this riveting nut exists
The riveting nut use that the dismountable type liner collar can become general only need to be unloaded under the conditions of common riveting.

Detailed description of the invention
Further illustrate the technical solution of the utility model below in conjunction with the accompanying drawings and by detailed description of the invention.
Referring to shown in Fig. 1 to Fig. 4, in the present embodiment, a kind of compound dismountable type step riveting nut includes riveting tube body
1, the head end of described riveting tube body 1 offers big stepped hole in being provided with outward extending shade body 2, and described riveting tube body 1
3, the bottom of described big stepped hole 3 offers screwed hole 4, described riveting tube body 1 is arranged with according to being riveted the pre-hole of workpiece
Big freedom in minor affairs dismantles the liner collar 5 selected, and described in the inner hole of the described liner collar 5, the external diameter of riveting tube body 1 is arranged, institute
Stating the liner collar 4 height, to be riveted workpiece 6 with big pre-hole consistent, the lateral wall of the described liner collar 5 offers and embedded prevents
Slip teeth 7.
Be riveted workpiece 6 for big pre-hole and little pre-hole be riveted workpiece 8 rivet time, the liner collar 5 is filled out automatically
Fill big pre-hole and be riveted the gap size between workpiece 6 and riveting nut, the riveting workpiece 8 then riveting normal with riveting nut of little pre-hole
Connect, the deformation automatically generated by big stepped hole 3, according to on-the-spot riveting condition automatic moulding bulge 9, the size of bulge 9 by
Big pre-hole is riveted workpiece 6 and little pre-hole is riveted workpiece 8 total thickness and determines.
The tail end of described riveting tube body 1 is provided with the guide section 10 that cross-sectional area tapers into, and makes riveting by guide section 10
Connected nut more easily pass be provided with pre-hole be riveted workpiece.
When to be riveted workpiece rivet time, the rifle head on clincher tool pass shade body 2, riveting tube body 1, big step
Install with the screw thread in screwed hole 4 behind hole 3 and screw, inserted by the guide section 10 in outside the most together and be riveted on workpiece in advance
In the riveted holes held successfully, then it is pulled outwardly.Riveting tube body 1 upper end is made to be forced into bird-caging bulge portion outward expansion, until at quilt
Form bird-caging bulge 9 inside riveting piece, make to be riveted piece-holder at this bird-caging bulge 9 and the shade as spacing plane
Between body 2.
Now when being riveted on workpiece the different grip of appearance and riveting pre-bore dia, the riveting that riveting condition is more complicated
During T-Ring border, then common riveting nut cannot normally work；And the liner collar 5 of this riveting nut is i.e. for this feelings
Condition, completes efficiently to rivet.Under above-mentioned case conditions to be riveted workpiece rivet time, need to be at the outer sheath of riveting tube body 1
The upper liner collar 5 is also pushed into the root of shade body 2, and the rifle head on clincher tool passes shade body 2, riveting tube body 1, big platform
Install with the screw thread in screwed hole 4 behind hole, rank 3 and screw, insert big pre-hole by the guide section 10 in outside the most together and be riveted work
In part 6, the height of the liner collar 5 is riveted the highly consistent of workpiece 6 with big pre-hole.Insert little by guide section 10 the most together
Pre-hole is riveted workpiece 8, is finally pulled outwardly, and makes riveting tube body 1 upper end be forced into bird-caging bulge outward expansion, until at quilt
Form bird-caging bulge 9 inside riveting piece, make to be riveted piece-holder at this bird-caging bulge 9 and the shade as spacing plane
Between body 2.
Above example simply elaborates ultimate principle of the present utility model and characteristic, and this utility model is not by above-mentioned example
Limiting, on the premise of without departing from this utility model spirit and scope, this utility model also has various change and change, and these become
Change and change in the range of both falling within claimed this utility model.This utility model claims scope and is wanted by appended right
