Abstract
The invention discloses an anti-revolving automobile bolt. The anti-revolving automobile bolt comprises a bolt head, a screw rod and a thread; the bottom face of the bolt head stretches downward to form the screw rod, and the thread is formed on the outer edge of the screw rod; the thread on the screw rod is provided with a nut, a steel ring and a flat washer which are matched with the thread, a flange plate integrated with the nut is arranged on the nut, one side of the bolt head is provided with a stabilizing face, the stabilizing face is a concave face, and the concave face is composed by two oppositely arranged flats. According to the anti-revolving automobile bolt, the stabilizing face is composed by two relatively arranged flats, so that the space between the stabilizing face and a hub is enlarged; friction generating in screwing process or disassembling process is reduced, so that damage on the hub is prevented; the hub can be clamped to prevent the hub from rotating, and the usability of the product and the security coefficient after being assembled into an automobile are improved; at the same time, the processes of the processing technique is reduced greatly, so that rate of finished products and the production efficiency are improved.
Description
[technical field]
The present invention relates to a kind of fastening piece of automobile, be specifically related to a kind of anti-rotational automobile bolt and processing technology thereof.
[background technique]
The wheel hub of automobile with realize being connected by bolt between steel ring, in order to the convenience of installing and fastening after stability, the side of bolt head is generally all provided with stabilising surface, stabilising surface adopts arc surface, and its radian matches with the wheel hub cambered surface contacted, when bolt is in the situation tightened or dismantle, although can prevent bolt from rotating, but cause the friction between bolt head stabilising surface and wheel hub cambered surface to become greatly, the permanent time can cause wheel hub cambered surface to be worn and torn, reduce the safety coefficient of automobile.The operation of this bolt processing technic featuring is loaded down with trivial details simultaneously, and product rejection rate is large, and manufacturing efficiency is low, and processing cost is high.
Therefore, for avoiding above-mentioned technical problem, the necessary one that provides has structure improved anti-rotational automobile bolt, to overcome described defect of the prior art.
[summary of the invention]
In order to overcome above shortcomings part in prior art, the object of the present invention is to provide a kind of structure simple, fastening stable, and reduce the anti-rotational automobile bolt of wheel hub friction damage.
In order to reach above-mentioned object, the present invention adopts following concrete technological scheme: anti-rotational automobile bolt, comprise bolt head, screw rod that bolt head bottom surface extends to form downwards and the screw thread that is formed in described screw rod outer rim, screw flight is provided with the nut, steel ring, the plain washer that match with it, nut is provided with integrated flange plate with it, bolt head side is provided with stabilising surface, and described stabilising surface is concave surface, and concave surface is oppositely arranged by two planes and forms.
Further, the angle of two planes of the present invention is 95 ° ~ 175 °.
Further, the cross section of concave surface of the present invention is ridge.
Further, the upper end of bolt head of the present invention is arc.
Further, the dual-side that spacing of the present invention increases gradually is circular arc line, and namely bolt head both sides are cambered surface.
The processing technology of above-mentioned anti-rotational automobile bolt, comprises the steps:
1) size on demand prepares cylindrical round steel stock;
2) by overclocking stove, described stock one end is heated;
3) adaptive mold and punching head is adopted to carry out impact briquetting to blank heating end;
4) heat-preservation cylinder is put into the cylindrical body stock of step 4) drawing, treat that nature cools;
5) roll threading process is carried out to the described blank the other end;
6) finally by lathe, deburring is carried out to impact briquetting stock end.
The present invention's advantage is compared with prior art: the stabilising surface that the present invention is oppositely arranged by two planes, the spacing between stabilising surface and wheel hub is made to become large, reduce in the friction of tightening or dismantling generation, thus prevent the wearing and tearing of wheel hub, again can clamping wheel hub and prevent rotate, improve the safety coefficient after the usability of product and entrucking, processing technology operation of the present invention greatly reduces simultaneously, thus improves finished product rate and manufacturing efficiency.
[accompanying drawing explanation]
Fig. 1 is structural representation of the present invention;
Fig. 2 is the structural representation of bolt head of the present invention;
Fig. 3 is the structural representation of bolton of the present invention on wheel hub;
Below in conjunction with accompanying drawing, the present invention is described in further detail.
[embodiment]
In order to explain technological scheme of the present invention further, below by specific embodiment, the present invention will be described in detail.
Refer to shown in Figure of description 1 to Fig. 3, the present invention is anti-rotational automobile bolt, comprise bolt head 1, the screw rod 2 that bolt head 1 bottom surface extends to form downwards and the screw thread 3 be formed in described screw rod outer rim, screw flight 3 is provided with the nut 4 matched with it, steel ring 5, plain washer 6, nut 4 is provided with integrated flange plate with it, bolt head 1 is in more flat Cylindrical object, its cross section upper end 7 is narrower, lower end 8 is wider, for spacing increases the cambered surface on left side 9 and right side 10 gradually between upper end 7 and lower end 8, bolt head 1 lower end is the stabilising surface 11 with hub contacts, upper end 7 is cambered surface, lower end 8 is concave surface, concave surface cross section is ridge, concave surface is oppositely arranged by two planes and forms, wherein the angle a of two planes is 170 °, like this can better with hub contacts and clamping wheel hub, preventing rotates and rub becomes large, reduce the wearing and tearing of wheel hub and bad.
The processing technology of the anti-rotational automobile bolt of the present invention, comprises 1) size on demand prepares cylindrical round steel stock; 2) by overclocking stove, described stock one end is heated; 3) adaptive mold and punching head is adopted to carry out impact briquetting to blank heating end; 4) heat-preservation cylinder is put into the cylindrical body stock of step 4) drawing, treat that nature cools; 5) roll threading process is carried out to the described blank the other end; 6) finally by lathe, deburring is carried out to impact briquetting stock end.
But above-mentioned embodiment is exemplary, being to better enable those skilled in the art understand this patent, can not being interpreted as it is restriction this patent being comprised to scope; As long as according to this patent disclose any equivalent change done or the modification of spirit, all fall into the scope that this patent comprises.
