摘要
针对陀螺框架高精度垂直孔系加工精度影响因素多且无综合分析测评方法的工程实际,采用齐次坐标变换的分析方法,建立了坐标镗床上应用转台精镗陀螺框架孔的同轴度误差模型,设计实现了误差分析软件,对陀螺框架的同轴度误差进行了定量分析,实现了陀螺框架加工误差的快速预测.加工试验结果表明该模型分析结论与加工试验结果具有较好一致性,分析方法对系列新产品开发具有指导作用.
The factors that affect the machining precision of the two couple vertical coaxial holes of the gyroscope frame are complex,and there is no effective integrated evaluation method in practice. Based on homogeneous coordinate transformation,a machining error model for the turntable of a coordinate boring machine is established, an error analysis tool which can quantify the major geometric tolerances of the turntable and quickly predict the machining error of the gyroscope frame is developed. The test results show that calculation errors are similar to the test data. The error model method submitted in the paper becomes the basis of the integral error model of the gyroscope frame machining systems.
