摘　　要：轴类零件加工时需要用夹具定位,夹具设计拼装过程中需要计算出定位圆中心到基准面的垂直距离(定位圆中心高),文章通过建立许昌烟草机械有限责任公司可用于轴类定位的所有组合夹具结构模型,把工件尺寸、组装尺寸及元件尺寸巧妙地通过尺寸模型图进一步推导中心高的数学模型及excel函数公式,实现定位圆中心高的快速自动计算。本发明国家已授权实用新型专利。When machining shaft parts,we need to use fixture positioning,and in the process of fixture design and assembly,we need to calculate the vertical distance from the positioning circle center to the datum plane(positioning circle center height).By establishing all the modular fixture structure models that can be used for shaft positioning in our company,the workpiece size,assembly size and component size are skillfully deduced from the dimension model diagram to further deduce the mathematical model of center height and excel function formula.The fast and automatic calculation of the height of the center of the circle is realized.For this invention,a utility model patent has been authorized by the country.
