[Abstract]:The traveling accuracy, vibration, noise and temperature rise of rolling linear guideway pairs are the important performance indexes to evaluate the quality and accuracy of processed parts. Therefore, the accurate measurement of the comprehensive performance of rolling linear guideway pair has important reference significance for improving the quality of guide rail pair in actual production. Based on the comprehensive performance test bed of rolling linear guideway pair and the actual working condition of the test bed, the possible design defects of the test bed are analyzed, and according to the analysis results, the weight loss of the test bed is analyzed. The optimization design of key parts is carried out from the angle of improving mechanical properties and vibration characteristics, and the safety performance of the whole test-bed is improved. The measuring principle and measurement method of motion accuracy, acceleration, vibration, friction, noise and temperature rise of linear guideway pair are studied based on the comprehensive performance test bed of rolling linear guideway pair. According to the design index of the test bed and the measuring principle of the comprehensive performance of the guideway pair, the software of the dynamic measurement system is compiled with Visual Basic as assembly language to realize the data acquisition and data processing of the sensor. Data saving and report generation and a series of functions. The comprehensive performance test of linear guideway pair is carried out, the concrete steps of the test and the problems needing attention are expounded. Under the same conditions, the same object was tested many times, and the results of the test data were analyzed by using the conventional statistical analysis method and the spectrum analysis method. The repeatability of the measurement results is evaluated by calculating the range of the measured data under the same measuring conditions, and the validity of the whole measurement system and the feasibility of the measuring method are verified by experiments.
