[Abstract]:Since the engine crankshaft has an important influence on the performance of the automobile, the manufacture of the crankshaft has become a key step in the automobile manufacturing industry. The transition groove is an important structure in the crankshaft, so that the stress on the journal is not concentrated, the fatigue damage does not occur when the crankshaft is used, and therefore, the key dimension of the crankshaft is measured with high precision, which is an important way to ensure the manufacturing precision and the performance efficiency of the crankshaft. With the improvement of the machining precision of the crankshaft of the engine, the precision requirement of the measurement is higher, and the precision and error compensation of the crankshaft image system can further improve the accuracy of the measurement, and it is very important. Based on the developed crankshaft image system, the factors affecting the measurement accuracy and error of the system are analyzed, and the analysis, optimization and optimization are carried out. This paper deals with the high quality image acquisition technology, improves the system hardware, optimizes the kernel algorithm and the proposed fast two-dimensional calibration method, and improves the image system of the crankshaft. The space error modeling method based on the multi-body system is studied, the space error of the crankshaft image system is systematically analyzed, and then the space error model of the crankshaft image system is established. The model is optimized and the model is optimized. The rapid measurement method of space error based on laser tracker is studied, including the measurement of the geometric errors of the crankshaft image system and the influence of the error on the crankshaft image system. The measurement results are analyzed and analyzed. In this paper, the system error modeling and error measuring method of crankshaft image based on laser tracker is experimentally verified. firstly, measuring and analyzing the geometric error of the crankshaft image system, measuring the motion error of the three-dimensional space and calculating the value of each error source, and finally verifying the system comprehensive error compensation precision,
