摘　　要：为了提高曲轴中心距检测效率及检测精度,根据V形支承定位理论,设计新型曲轴中心距检具,并进行实际曲轴中心距测量验证。新型曲轴中心距检具由V形支承、横梁、表座、百分表、圆柱销、菱形销、中空螺栓、定位柱组成。实际测量结果表明:设计的曲轴中心距检具的测量误差在±0.01 mm以内,满足现有产品公差不超过±0.1 mm的要求,测量结果波动小,与数控检测机床检测结果的最大偏差为0.005 mm,操作简单、检测效率高、适用范围广。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.
