Hexagon socket head cap bolts are widely used in the manufacturing and assembly of automotive chassis due to their unique design and high load-bearing capacity. These bolts are commonly used to secure various chassis components, such as suspension arms, brackets, and body structures.

[0003] In the existing technology, the installation technology of hexagon socket head bolts for automobile chassis faces the challenges of improving efficiency, ensuring precision, reducing costs, and enhancing adaptability. Patent document No. CN215634305U describes an impact-resistant bolt for automobile chassis. By providing a buffer spring and a spring limit nut on the bolt body, the buffer spring can absorb part of the impact force when the bolt body is subjected to a large impact, thereby enhancing the impact resistance of the bolt body. The utility model greatly enhances the connection stability between the fastening nut, spring limit nut, and washer by providing a gasket with a fastening nut connection end and a limit nut connection groove, a fastening nut with a tapered hole, and a spring limit nut with a frustum. This ensures that the bolt body and each nut are not prone to loosening for a long time.

[0004] However, this device is not convenient for automatically positioning the hexagon socket bolts when in use. During the production and maintenance process, workers or automated equipment may need to spend more time aligning the bolts and screw holes, thereby reducing the efficiency of the assembly line and increasing production time and labor costs.

[0005] Based on this, an automatically positioned automobile chassis hexagon socket bolt is now provided to eliminate the drawbacks of the existing device. Utility Model Content

The bolt is then screwed into the threaded hole, where the hole wall presses against the locking ball, compressing the second spring. When the locking ball slides into the locking groove in the hole, the second spring returns, and the locking ball embeds in the groove, firmly locking the bolt and ensuring precise positioning. This process simplifies the process of adjusting and securing the bolt length.

[0022] 2. The utility model realizes fast and automatic positioning of the bolt by sliding the positioning ramp in the guide groove of the automobile chassis. When the ramp reaches the top of the guide groove, the third spring pushes the limit block to embed into the threaded hole, indicating that the positioning is completed. At this time, the operator can immediately sense and tighten the bolt. This device significantly improves the efficiency and convenience of bolt positioning, brings great convenience to operation, and effectively promotes a leap in work efficiency.
