Material Selection and Structure Design of Auto Parts Inspection Tool

Among the auto parts inspections tools the one with complex structure and complete functions is the auto inspection tool. Compared with a single detection tool, the vehicle detection tool is more convenient to use, more practical, higher in efficiency and lower in cost. The vehicle inspection tool simulates the shape and structure of the actual car body, and realizes the inspection of most parts of the car body by simulating the matching gap and position relationship between the actual car parts and the vehicle inspection tool. For example, vehicle detection tools can detect the accuracy and matching relationship of front and rear windshields, bumpers, lights, doors, luggage covers, instrument panels, interior decoration and other components. As one of the auto parts, the car side wall has a matching relationship with many parts on the car body, such as four doors, tailgate, ABCD4-pillar decorative plate, car roof, wing plate, triangular window, fuel cover, etc. Whether they are qualified or not will not only affect the appearance of the car body, but also affect the quality and safety of the car. In recent years, the domestic inspection tool industry has broken the monopoly position of foreign enterprises through independent research and development and technological innovation, and produced more and more high-performance and cost-effective vehicle inspection tools, especially the use of new materials such as resin materials, which provided a great space for the development of lightweight and high-quality inspection tools in China. This paper introduces the development process of the side simulation block of the vehicle inspection tool based on the new paste resin material. In the process of automobile assembly, the automobile body is composed of thousands of parts, and the inspection tools play an important role in the assembly process. Through the use of inspection tools, after passing the test on professional inspection tools, you can directly install parts to ensure the smooth flow of the whole assembly line and solve the problem of interchangeability of automobile parts. Automobile inspection tool design is a kind of polymer composite material mixed with organic compounds and inorganic compounds. After physical changes and chemical reactions, it has been widely used in many industries because of its small deformation coefficient, stable size, good processability, good chemical stability, good acid and alkali resistance, low storage conditions and low density. Paste is another resin form, which is a semi-fluid resin before curing, and consists of two independent raw materials. The two materials can be uniformly stirred at room temperature, and can be cured into common bulk resin without other conditions, and the curing time is 12h or 16h. Paste resin has all the advantages of ordinary bulk resin after curing. Automobile parts have convenient molding and modification, moderate curing time, strong adhesion, small shrinkage, and no other by-products are discharged during curing. Products are widely used in the manufacture of inspection tools, models and fixtures.
