| Car body dimension control is one of the most important works of quality control in vehicle manufacture, realize better technics, improve brand. Many vehicle manufacture company has established a suit of systemic car dimension control system one by one, such as Europe and the United States, Japan and South Korea, equipped with a comprehensive means of measurement, monitor the dimension of car manufacture process, development many mature evaluation and analysis tools.Local brand usually adopt converse develop, usually they use the same measurement method, there is inadequate means of measurement, measurement items are not comprehensive, evaluation and analysis issues such as the more primitive, therefore, the level of car body dimension control is backward compared with Europe and the United States, Japan and South Korea.In this background, this paper fully learns from the experience of the international advanced enterprises, we use"Function dimension". The after-match parts of the installation process as the body dimension of the measurement elements of creative problem solving local brands mechanically 3D coordinate measurement points, the deviation of the measurement point is unable to determine the order of the impact of the problem and then can not be fast feedback processes analysis to solve problems, while a unified measure benchmarks and drawing benchmark, to achieve functional dimension and measurement points of the transformation, constructed an effective body dimension control system and automated analysis of monitoring data processing and networking.This article is expatiate that how to build based on functional dimension of the body dimension of control system, use functional diagram,module diagram to show system design, design for how to realize system database in logic and physics, and explain for system configuration and test. On this basis, with one models, for example depth of body dimension control system and development of the practical application. |
