Anti-revolving automobile bolt and processing technique thereof

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】 [0001] The invention relates to a fastener for an automobile, in particular to an anti-rotation automobile bolt and a processing technology thereof. 【Background technique】 [0002] The connection between the wheel hub and the steel ring of the car is realized by bolts. For the convenience of installation and the stability after fastening, the side of the bolt head is generally equipped with a stable surface. The stable surface adopts a circular arc surface. The arc surface of the hub that is in contact with each other coincides. When the bolt is tightened or disassembled, although the bolt can be prevented from rotating, it will cause greater friction between the stable surface of the bolt head and the arc surface of the hub, which will cause the arc surface of the hub to wear for a long time and reduce the damage of the vehicle. safety factor. Simultaneously, the procedure of the bolt processing technology is cumbersome, the product scrap rate is high...

[0002] The connection between the wheel hub and the steel ring of the car is realized by bolts. For the convenience of installation and the stability after fastening, the side of the bolt head is generally equipped with a stable surface. The stable surface adopts a circular arc surface. The arc surface of the hub that is in contact with each other coincides. When the bolt is tightened or disassembled, although the bolt can be prevented from rotating, it will cause greater friction between the stable surface of the bolt head and the arc surface of the hub, which will cause the arc surface of the hub to wear for a long time and reduce the damage of the vehicle. factor of safety

At the same time, the process of the bolt processing technology is cumbersome, the product scrap rate is high, the production efficiency is low, and the processing cost is high.
