According to the actual situation of existing detection technology at home and abroad, improving the level of measurement and developing the measurement technology are important parts of the automotive industry. In a sense, the level of detection represents the technical content of an enterprise. Now there is a very popular words: the life of the enterprise lies in the product and the life of product lies in quality. To ensure the quality of the product, stable and reliable measurement device is essential. In order to meet the requirements of modern automobile industry for the quality inspection of body manufacturing, automobile checking fixtures as the basic tool for testing, its design and manufacturing level are also rising. The traditional design methods and manufacturing processes have been phased out. CAD / CAM / CAE, Group Technology and reorganization of flexible technology and other advanced technologies began to widely used.
For the automobile manufacturing enterprises, the future development trend is multi-vehicle type, small batch and on-demand production. In the design and manufacture of checking fixtures, the combination and reusability of checking fixture, and the combination of computer-aided technology and the design and manufacturing process of checking fixture will be the future direction of checking fixture.
In order to meet the need of shortening the transformation period of automobile products, automobile manufacturers in developed countries such as USA, Germany and Japan have changed the traditional design method of checking fixture, and proposed a modular design method. In the checking fixture design and manufacturing process make use of a large number of common parts, and the use of modular combination of methods, quickly and effectively complete the test.
