Abstract
The invention relates to a high-torsion rivet hole, which is a through hole arranged on a plate and comprises a section of straight hole and a section of conical hole. A small orifice of the conical hole is communicated with one end of the straight hole, the other end of the straight hole is opened on a surface of the plate, a large orifice of the conical hole is opened on another surface of the plate, the inner wall of the conical hole is wavy peripherally, and each bump of the inner wall of the conical hole is used as an anti-rotating rib. When the rivet hole is used, the structure of the rivet hole does not need to be changed, and the high-torsion rivet hole is high in torsion, reliable in use and convenient in manufacture.
Description
Technical field
The present invention relates to metal and connect, relate in particular to a kind of rivet hole of high torsion.
Background technique
Rivet, a kind of metallic one end has the shaft-like part of cap, penetrates by behind the rivet hole of coupling member, beats, extrudes the other end in the outer end of bar, and member is compressed, fixes.When connecting sheet material or sheet material, usually use rivet to connect, and connecting the part that different materials is processed, and can not weld, soldering or when bonding, need use rivet to connect more.
At present when using rivet to connect sheet material; Normally rivet is located in the rivet hole of offering on the sheet material, this rivet hole is the straight hole that cooperates with rivet nail body, and then tool using knocks the groove of offering on the rivet; Groove is destroyed; Make groove expand outwardly and form a section, this section is close on the sheet material, thereby reaches the effect of riveted joint.But the recessed folding of section that forms through the destruction groove is under the high twisting force, and easy and sheet material gets loose, if be under the effect of high torsion for a long time, will rupture in the recessed folding of section place, make rivet separate with sheet material, thereby makes the riveted joint of rivet lose efficacy.
Use the torsion that following several method strengthens rivet at present in the industry always: 1, strengthen rivet diameter, normal in the industry through strengthening the diameter of rivet, with the warping force of increase rivet, but need to change product structure, product development cycle will elongate, and cost will improve; 2, adopt the rivet hole of anistree shape, machining shape is complicated, and cost is also high, but the torsion that improves can only reach common 1.2 ~ 1.5 times.So the present invention proposes a kind ofly need not to change the structure of rivet, high torsion, it is reliable to use, and is convenient to the rivet hole of making simultaneously again.
Summary of the invention
The present invention provides a kind of high torsion rivet hole, and its purpose is need not change the structure of rivet, has high torsion simultaneously again, uses reliably, is convenient to make.
For achieving the above object; The technological scheme that the present invention adopts is: a kind of high torsion rivet hole; This rivet hole is the through hole that is opened on the sheet material, and said rivet hole comprises one section straight hole and one section taper hole, and the osculum of this taper hole is communicated with an end of straight hole; The other end of straight hole opens at the one side of sheet material, and the big mouth of taper hole opens at the another side of sheet material;
The inwall of taper hole is along circumferentially being the fluctuating shape, and each road protuberance is as a resistance convulsion.
Related content in the technique scheme is explained as follows:
1, in the such scheme, said resistance convulsion upwards evenly distributed in the week of taper hole inwall.
2, in the such scheme, a side plane angle of the inwall of said taper hole and sheet material is 90 ° ~ 120 °, and a said side plane is the plane of big mouthful of place side of taper hole.
Working principle of the present invention is: through producing undulations on the rivet hole that connects sheet material at need; When riveted joint; The material of rivet is flow in the undulations of rivet hole, increased the frictional force between rivet and the sheet material, thereby solved the not enough problem of riveted joint torsion.
Because the technique scheme utilization, the present invention compared with prior art has advantage:
1, because the present invention has changed the structure of rivet hole, on the taper hole inwall, set up the resistance convulsion, the frictional force when having increased riveted joint between rivet and the rivet hole efficiently solves the not enough problem of riveted joint torsion.
2, the present invention need not change rivet shape and structure, is applicable to existing rivet.
3, because the present invention is simple in structure, low cost of manufacture, and be convenient to safeguard.
Description of drawings
Accompanying drawing 1 is structural perspective of the present invention;
Accompanying drawing 2 is plan view of the present invention;
Accompanying drawing 3 is sectional view of the present invention;
Accompanying drawing 4 is the present invention and rivet schematic representation.
In the above accompanying drawing: 1, sheet material; 2, rivet hole; 3, resistance convulsion; 4, taper hole; 5, straight hole; 6, rivet.
Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further described:
Embodiment: a kind of high torsion rivet hole
Shown in accompanying drawing 1; This rivet hole 6 is for to be opened in the through hole on the sheet material 1, and said rivet hole 2 comprises one section straight hole 5 and one section taper hole 5, and the osculum of this taper hole 5 is communicated with an end of straight hole 5; The other end of straight hole 5 opens at the one side of sheet material 1, and the big mouth of taper hole 4 opens at the another side of sheet material 1;
The inwall of taper hole 4 is along circumferentially being the fluctuating shape, and each road protuberance is as a resistance convulsion 3.
Establish two resistance convulsions 3 on the inwall of taper hole 4, resistance convulsion 3 upwards evenly distributed in the week of taper hole 4 inwalls.
One side plane angle of the inwall of said taper hole 5 and sheet material 1 is 120 °, and a said side plane is the plane of big mouthful of place side of taper hole 4.
When riveted joint; The nail body of rivet 6 stretches into from straight hole 5 ends of rivet hole 2; Stretch out from the big opening end of the taper hole 5 of rivet hole 2, use Riveting Tool to beat the part that rivet 6 stretches out, the material of rivet 6 is flow in the undulations of rivet hole 1; Increase the frictional force between rivet 6 and the sheet material 1, thereby solved the not enough problem of riveted joint torsion.
In the above-described embodiments, taper hole 4 inwalls of rivet hole 2 are provided with two resistance convulsions 3, when practical application, can adjust the quantity of resistance convulsion 3 as required; Taper hole 5 is 120 ° with a side plane angle of sheet material 1 in the foregoing description, when practical application, preferably, can adjust angle as required in 90 ° ~ 120 ° scopes.
The foregoing description only is explanation technical conceive of the present invention and characteristics, and its purpose is to let the personage who is familiar with this technology can understand content of the present invention and enforcement according to this, can not limit protection scope of the present invention with this.All equivalences of doing based on spirit of the present invention change or modify, and all should be encompassed within protection scope of the present invention.
