摘要
在实际工程中,受加工、装配以及工作环境等因素的影响,通常存在一定的误差,为了减少误差带来的不确定性,针对转动机构的产品特征,分析了容差设计与设计、工艺、制造、装配等精密机械研制过程之间的联系,提出了适合机构产品的装配方法,总结出装配过程中调整法及修配法的计算步骤。针对天线转动机构驱动部件进行容差分析,利用装配调整法设计调整方案。
In practical engineering,due to the influence of processing,assembly,working environment and other factors,there are usually some errors.In order to reduce the uncertainty brought by the errors,according to the product characteristics of the rotating mechanism,this paper analyzes the relationship between tolerance design and the development process of precision machinery such as design,process,manufacturing,assembly,etc.,puts forward the assembly method suitable for the product of the mechanism,and summarizes the calculation steps of adjustment method and repair method in assembly process.According to the tolerance analysis of the driving parts of the antenna rotating mechanism,the assembly adjustment method is used to design the adjustment scheme.
