摘要
针对火箭部段对接孔数字量协调的难点,分析数字量协调加工的影响因素确定要因,并通过对比试验和理论分析的方法分析测量误差和定位误差两种要因对加工精度的影响。在此基础上,提出数字量协调加工控制方案,并以典型部段端框为对象开展协调制孔试验,试验结果表明,数字量协调加工孔位精度符合装配协调要求,与工装平台试对协调,为端框数字量协调加工的工程化应用奠定了基础。
In the view of the difficulty of digital coordination of coordination hole of the carrier rocket part,the influencing factors of digital coordination processing are analyzed and the main reasons are determined,and the influence of measurement error and positioning on the machining accuracy is analyzed through comparative test and theoretical analysis.On this basis,the digital coordinated machining control scheme is put forward,and the typical part is taken as the object to carry out coordinated hole test,the test results show that the digital quantity coordination machining hole position accuracy meets the requirements of assembly coordination,and the test coordination with the tooling platform,laying the foundation for the engineering application of the end-frame digital quantity coordinated machining.
