[Abstract]:The main research content of this paper is the development of automatic testing equipment for hydraulic lock in automobile cab, which solves the problem that the detection efficiency in the process of single station testing is not high, pure manual or semi-automatic, and low labor efficiency. At the same time, the equipment can meet the testing requirements of many hydraulic locks with one set of equipment, with high quality and reliability, good man-machine interaction, According to the technical requirements of hydraulic lock detection, this paper aims at solving the problems of low detection efficiency and low detection precision, and designs the best technical scheme of hydraulic lock detection equipment. The structure of automatic testing equipment for hydraulic lock is divided into four subsystems: rotating tooling system, tension and compression testing system, oil pressure detecting system and electric control system. The optimal mechanical structure model of each subsystem is designed by using the three-dimensional software SOLIDWORKS and the theory knowledge of sensor and test technology. The transient dynamics of the hydraulic lock detector is analyzed by using the ANSYS WORKBENCH finite element analysis software. Fatigue life analysis and optimization design analysis verify the rationality and feasibility of the scheme design of the key mechanical structure of the equipment, and provide a reliable technical guarantee for the realization of the whole design scheme. According to the function and structure characteristics of each subsystem and the testing technology requirements of hydraulic lock, the gas liquid system is selected as the driving detection system, and the testing technology requirements of the hydraulic lock are also introduced in accordance with the testing technical requirements of the hydraulic lock and the working conditions of the enterprise. According to the technical requirements of gas-liquid, calculate the specific parameters of the gas-liquid booster pump, calculate the inner diameter of the loading cylinder according to the technical requirements to be tested, Parameters such as stroke. The electrical control principle diagram is designed according to the testing function requirements of the equipment. Siemens PLC is chosen as the logic controller of the tester. Through the comprehensive application of electro-hydraulic control technology and sensor measurement technology and theory, The automatic detection of hydraulic lock is realized, and man-machine interaction and real-time monitoring data are realized through touch screen. Finally, according to the technical requirements of hydraulic lock detection, The experimental results show that the tester runs stably, has high reliability and has good effect.
