Amount of special fixture is widely used in the production of auto parts of non-standard test equipment. Because of its simple structure, easy to use, the cost is relatively low, particularly suitable for mass production as the characteristics of the automobile manufacturing industry, tens of thousands of the amount of special fixture used in auto parts and components manufacturing process between testing and testing of the final product. Along with the development of detecting technology, although more and more general measurement test equipment in various forms into the production site, but does not replace the traditional detection methods. Reason is the rapid development of auto industry also drove the car parts dedicated testing equipment technology high speed progress, its application scope and structure characteristics are also a huge change.

　　Dpca testing equipment is a dragon technology center quality inspection department to make overall planning and investment management, on the process design using a large number of special fixture, paragraphs to ensure that the key of the auto parts and safety quality item and regulations. Not only on the production line is equipped with a large number of special measuring tool, such as all kinds of links, check gauge, gauge, card board, depth gauge, etc.; Also equipped with a large number of special fixture, such as parallelism fixture, verticality, beating fixture, alignment gauge, location, degree of integrated fixture, etc.; At the same time also can equipped with many detection at the same time size and geometric error flexibility dedicated testing equipment; Is equipped with a certain number of special high efficient and comprehensive testing equipment - final inspection machine. These dedicated testing equipment configuration to improve the measurement efficiency, effectively control the quality of the product, in the end to ensure the use function of the product. The first phase of dpca is only used for testing equipment investment cost is as high as 650 million yuan, the special testing equipment investment costs accounted for nearly 400 million yuan. Below to dpca production of car engines, rest, transmission, and other products dedicated testing equipment with characteristics of xiangfan plant as an example, talk about the auto parts industry in our country in recent years the development of special testing equipment.
