1、 Automotive fastener structure
Automotive fasteners include various standard and non-standard fastening elements that are fixed and connected to the entire vehicle. Bolts, screws, etc. are connected to the main body through threaded fastening. According to the number of parts, the proportion of fasteners in the total number of vehicle parts far exceeds that of any other parts, reaching 40% to 55%; The final assembly process of the entire vehicle mainly uses fasteners to connect various components; Accidents and fatalities caused by some fastener failures also occur from time to time. Therefore, fasteners should be very important for the manufacturing and use of automobiles, but in fact, automotive fasteners have not received widespread and sufficient attention in China. This is a question worth discussing. Here, the author attempts to conduct a preliminary discussion on this for reference only.
2、 The Importance of Automotive Fasteners
The importance assessment of automotive fasteners requires the establishment of a standard or guideline to evaluate the importance of automotive fasteners or all automotive components. The automotive industry seems to have an inertia thinking that the more complex the technology and the more difficult the manufacturing, the more important it becomes. For example, in the small car fastener industry, the term "high-strength fasteners" has been popular for many years and has been included in national policy documents. A typical example. Indeed, high-strength fasteners are often important fasteners, but it should also be said that this is not entirely the case. Obviously, this is a classification standard based on "manufacturer status". Since the only consumers of cars are people, the general public, the most reasonable and ultimate principle should be to evaluate from the "user's perspective". The question is how to make this principle more specific.
Key points for making automotive fasteners
Effective management and control must be carried out throughout the entire process of designing and manufacturing automobiles and their components. Obviously, this can only rely on centralized management departments such as automobile manufacturing, transportation, maintenance, and spare parts sales. Quality supervision, business management and other departments collaborate and carry out work from multiple perspectives. Firstly, prioritize the management of the 'security aspect'. If the automotive industry includes it in the scope of product certification, production licenses, etc., gradually realizes licensed production, and gradually prohibits the production of unlicensed and unqualified "safety components" within a certain period of time; Implement quality supervision and inspection by the automotive industry and quality supervision departments; The industrial and commercial department shall manage the circulation of unlicensed and unqualified "security components"; The relevant management department controls and restricts the use of unlicensed and unqualified "safety components" in the parts sales and maintenance industry... waiting. Obviously, the key is to control the source of the product.
