Abstract：In order to improve the efficiency and accuracy of crankshaft center distance inspection,a new type of measuring tool for the crankshaft center distance is designed based on the V-shaped support positioning theory,and actual crankshaft center distance measurement verification is carried out.The new measuring tool for the crankshaft center distance consists of a V-shaped support,crossbeam,gauge seat,dial gauge,cylindrical pin,diamond pin,hollow bolt,and positioning column.The actual measurement results show that the measurement error of new measuring tool for the crankshaft center distance is within±0.01 mm,which meets the requirement of existing products with an error not exceeding±0.10 mm.The measurement results have small fluctuations,and the maximum deviation compared to the detection results of CNC testing machines is only 0.005 mm.The measureing tool is easy to operate,has high detection accuracy,and can detect the center distance of various types of crankshafts.
