[Abstract]:With the development and popularization of intelligent manufacturing, it provides a powerful foundation for the construction of digital workshop and digital factory. In the boiler manufacturing industry, the butt welding of the boiler drum segment occupies a very important position, and the measurement of the inner diameter of the cylinder joint is the basis to achieve the best welding state. The application of intelligent laser measurement and intelligent pairing method can solve the problem that the key production parameters such as product quality and production benefit can not be accurately measured, in order to improve the production benefit. Ensuring the quality of the product provides a powerful means. In this paper, a non-contact laser measurement method is used to effectively realize accurate, fast and stable multiple measurements of the inner diameter of the cylinder knots, and the data can be sent out synchronously. The measurement system is realized by axial alignment, coaxial centering, rotating positioning, scanning measurement, and wireless communication transmission technology is adopted to avoid the inconvenience caused by wire winding. The system can not only measure the inner diameter of drum knots in real time, but also complete the matching quickly and effectively. To meet the digital workshop intelligent manufacturing automation production requirements. This paper first introduces the present situation of domestic and international research on the measurement method of large aperture inner diameter, and the bottleneck of the existing technology in our country, and the deficiency in boiler manufacture, then designs a non-contact method using laser. The measuring system for measuring the inner diameter of boiler tube is simple in structure, high in measuring accuracy and accurate in rotation and positioning. A real-time and reliable measuring system is designed to realize the functions of sensor scanning, wireless communication, motor driving and so on. The function of the system is to realize the hardware design and software development of the measurement system by using ARM chip and C language program, and to transmit the measured data to the host computer in real time and effectively by using the ZigBee wireless communication technology. Avoid wire-winding interference in data acquisition.
