The 12V240 diesel locomotive used in diesel locomotives running on China's railways has a complicated structure and strict dimensional and shape position requirements. Previously, the measurement of the roundness and cylindricity of the main bearing hole was measured by the two-point method. Due to the low measurement accuracy, it was not intuitive (cannot display the actual circular pattern). The actual circle was once the main quality of our factory. problem. After three years of hard work, we have successfully developed a measuring device for measuring the main bearing hole of the diesel engine body φ235_0~(+0.046)mm, roundness and cylindricity error of 0.02mm, and can print the measurement results. The measuring device also has certain reference value for measuring the roundness and cylindricity error of other box parts.
