本文对实际生产中应用很广、现场工程技术人员不易掌握其定位精度计算的“一面双孔”定位系统定位误差的计算方法作了深入的分析、并推导出可供现场使用的简便计算公式,尤其是变针对一种定位系统的计算公式为适应多种定位系统的通用公式,从而为机床夹具设计中定位精度计算的系统化、自动化开辟了一条新途径。
In this paper, the calculation method of positioning error of “one side and two holes” positioning system which is widely used in the actual production is widely analyzed and the on-site engineers and technicians are not easy to grasp the calculation of the positioning accuracy, and the simple calculation formula available for on- In particular, the calculation formula that is adapted to a positioning system is a general formula adapted to a variety of positioning systems, thus opening up a new way for systematizing and automating the calculation of the positioning accuracy in the design of machine tool fixtures.
