Description
Technical field
This utility model belongs to positioning fixture technical field, relates in particular to a kind of screw-rolling machine rolling ring-grooved rivet and breaks neck
The positioning fixture of groove.
Background technology
Ring-grooved rivet (HB5501, HB5506 etc.) is the class rivet that on aircraft, usage amount is bigger, according to standard-required, ring
Groove rivet need to roll cut-off neck slot, and before cut-off neck slot, polished rod length dimension requires and tolerance less (such as Fig. 5).Ring-grooved rivet breaks at present
Neck groove is formed by screw-rolling machine rolling, and screw-rolling machine uses location bar location (such as Fig. 6), owing to ring-grooved rivet blank is by cold headers upsetting system
Forming, cold-heading product end section is the most smooth, and when causing screw-rolling machine location bar to contact part end, position is inconsistent, and rolling
Before pressure, product this body length of blank is variant, causes product rolling cut-off neck slot time pole length size fluctuation bigger.
Summary of the invention
The purpose of this utility model is to overcome disadvantages mentioned above and a kind of simple in construction provided, the most reliable, operation side
The positioning fixture of the screw-rolling machine rolling ring-grooved rivet cut-off neck slot that just, environmental protection is practical.
This utility model purpose and solve its technical problem underlying and realize by the following technical solutions:
The positioning fixture of screw-rolling machine of the present utility model rolling ring-grooved rivet cut-off neck slot, including sheet, a fluting, wherein:
Sheet top is provided with fluting, and a sheet is arranged between roller A and roller B, and fluting is positioned at roller A and the sidepiece of roller B.
The positioning fixture of above-mentioned screw-rolling machine rolling ring-grooved rivet cut-off neck slot, wherein: slot as rectangular recess.
The positioning fixture of above-mentioned screw-rolling machine rolling ring-grooved rivet cut-off neck slot, wherein: a sheet top is up-narrow and down-wide isosceles
Trapezoidal, bottom is rectangle.
This utility model compared with the existing technology has clear advantage and beneficial effect.From above technical scheme,
In the positioning fixture of screw-rolling machine of the present utility model rolling ring-grooved rivet cut-off neck slot, a sheet top is provided with rectangular slot, passes through
The head of rivet part positions, and avoids the rivet polished rod length dimension change that the bar portion overall dimensions change of rivet brings,
Also the inconsistent rivet polished rod caused of contact position that when using location bar, blank end section out-of-flatness causes is avoided long
Degree change in size, drastically increases the concordance of rivet polished rod length dimension.In a word, this utility model simple in construction, accurately
Reliably, practicality convenient and environmental-friendly to operate, be suitable for screw-rolling machine rolling ring-grooved rivet cut-off neck slot location processing promote the use of.

Detailed description of the invention
Below in conjunction with accompanying drawing and preferred embodiment, break neck to according to the screw-rolling machine rolling ring-grooved rivet that the utility model proposes
Positioning fixture detailed description of the invention, structure, feature and effect thereof of groove, after describing in detail such as.
Seeing Fig. 1 to Fig. 3, the positioning fixture of screw-rolling machine of the present utility model rolling ring-grooved rivet cut-off neck slot, including a sheet
1, fluting 2, wherein: sheet 1 top is provided with fluting 2, a sheet 1 is arranged between roller A3 and roller B4, and fluting 2 is positioned at rolling
Wheel A3 and the sidepiece of roller B4.Fluting 2 is rectangular recess.Propping up sheet 1 top is up-narrow and down-wide isosceles trapezoid, and bottom is rectangular
Shape.
During use, seeing Fig. 4, the screw-rolling machine that rivet part 5 is placed upside down in the transformation of the way props up on sheet 1, and the head of rivet part 5 is put
Entering in fluting 2, the bar portion of rivet part 5 leans against on a sheet 1, is inverted by roller A3 and roller B4, it is achieved a sheet 1 of screw-rolling machine is fixed
Position rolls the cut-off neck slot 8 obtaining ring-grooved rivet 6.This utility model is positioned by the head of rivet part 5, avoids rivet
The rivet polished rod 7 length dimension change that the bar portion overall dimensions change of part 5 brings, blank end when also avoiding employing location bar
The inconsistent rivet polished rod 7 length dimension change caused of contact position that end-grain cutting section out-of-flatness causes, drastically increases riveting
The concordance of nail polished rod 7 length dimension.
The above, be only preferred embodiment of the present utility model, not this utility model is made any in form
Restriction, any without departing from technical solutions of the utility model content, according to technical spirit of the present utility model to above example
Any simple modification, equivalent variations and the modification made, all still falls within the range of technical solutions of the utility model.
