As an important connecting part in the automobile assembly process, the screw plays a vital role in the safety performance of the automobile. The assembly of each component of the vehicle cannot be separated from the function of the screw. In the connection of the automobile assembly and its parts, the screw connection As well as simple structure, easy maintenance and disassembly, it is widely used. There may be thousands of screws on a car. The screw connection of each part has its own function and function. Once one or some screw connections fail, it will be It will lead to the loosening or even separation of the connected parts. If the car is running, it is likely to cause some parts to fail or break away. The light ones will cause the main functions of the car such as steering and braking to fail, potentially affecting driving safety. If it is not found in time, it will lead to major safety accidents and even endanger the lives of people. The failure of the car screws will cause the safety hazard of the whole vehicle, and will also cause customers to worry and complain, thus affecting the reputation of the company and endangering the life of the company. cycle.
In another embodiment of Guangdong Yueluo Hardware Industry Co., Ltd., the discharge port of the vibrating plate 2 is matched with the screw receiving hole 35, and the screws can enter the screw receiving hole 35 through the discharge port after sorting and sorting in the vibrating plate 2. . Preferably, a guide rail 6 is provided between the discharge port of the vibrating plate 2 and the screw accommodating hole 35 , and the screws enter the screw accommodating hole 41 from the discharge port through the guide rail 6 . The slotting is carried out, which improves the efficiency and saves the labor cost.
The hexagonal flange surface nut mainly includes a nut body, a flange surface is fixed at one end of the nut body, and a cap is fixed at the other end of the nut body. Has good sealing and corrosion resistance. The hexagonal flange surface nut mainly includes a nut body, a flange surface is fixed at one end of the nut body, and a cap is fixed at the other end of the nut body; since the cap is set on the nut body, it has the Better sealing can effectively prevent rain, moisture, dust and other harmful substances from immersing in the nut body, prevent the nut body from rusting, and greatly extend the service life of the hexagonal flange nut.
Fasteners are also divided into different types according to different uses, and new types of fasteners are developed according to the needs of special environments to meet the needs of all walks of life. The gasket combination bolt is a common fastening bolt. The combination gasket protects the surface of the connected parts from scratches, disperses the pressure on the connected parts, and has a sealing and anti-loosening effect. It is widely used. With the continuous improvement of requirements, the new zinc-aluminum coating surface treatment has gradually become the mainstream surface treatment process because it meets the environmental protection requirements, the surface is beautiful, and the corrosion resistance strength is higher than that of the zinc-nickel surface treatment.
