摘　　要：定心机构广泛应用于深孔类零件内孔测量装置中,定心机构的定心精度是影响测量误差的关键因素。文中分析了齿轮齿条定心机构、杠杆滑块定心机构和伞状定心机构的工作原理和定心误差,并对3种机构的定心误差大小进行了比较,结果表明伞状定心机构定心精度显著高于其他两种定心机构的定心精度。The centering device extensively is applied to inner diameter measurement of the deep bore parts,and the enter location precision of the centering device is a key factor to the measurement accuracy. In this paper,the principles and the centering error range of the rack gearing device,lever-slider device and umbrella-like centering device were analyzed and compared.The results showed that the enter location precision of the umbrella-like centering device had higher centering precision.

关 键 词：定心误差 伞状定心机构 杠杆滑块机构 齿轮齿条机构
