Description

Technical Field

[0001] The utility model belongs to the technical field of automobile parts processing, and in particular relates to a nut fastening platform for installing a click plate on a steering wheel. Background Art

[0002] Cars are one of the indispensable means of transportation in modern society, and the steering wheel is one of the core control devices in car driving. In modern car design, the steering wheel is not only a tool for steering, but also integrates various control buttons to provide additional functions and convenience. Among them, the horn button, also known as the horn button or horn switch, is one of the important safety devices and is placed in the steering wheel housing so that the driver can issue an alarm signal when needed.

[0003] At present, the click plate is installed in the shell by a bolt assembly, and needs to go through a processing procedure of pre-tightening before tightening. After pre-tightening, it needs to be tightened. Due to the requirements of the assembly process, if the screw is turned from the top, the rubber pad will be worn, so the screw cannot be turned, and the nut can only be tightened from the back. The traditional tightening method is to manually lift the steering wheel to press the upper screw forward, and then tighten the nut from the bottom. Although this operation method can be completed by one person, it is troublesome and laborious to operate, and the processing efficiency is still low. Although the existing technology has designed a matching automatic tightening device, when the staff lifts the steering wheel upward to tighten the screw, the matching device below rises to the corresponding position to automatically tighten the nut. Although it is more convenient and efficient, the cost of the matching automatic tightening device is high. For some small and medium-sized enterprises, these investments may exceed their affordability, and the corresponding maintenance costs will also bring a considerable burden.

[0004] Therefore, we propose a nut fastening platform for installing a click plate on a steering wheel to solve the above technical problems. Utility Model Content
