摘要
研究装配精度,采用有效的装配方法,对保证产品的质量有着十分重要的意义。文章主要介绍了CKA6150数控车床床头箱在整机总装关键工序中的装配工艺技术及精度检验方法,对床头箱与床身的位置精度、冷态精度和热态精度的相互关系、主轴热位移偏差方向等方面进行了分析研究。在数控车床的现场装配过程中,应用这种装配技术,对于保证机床整机精度的可靠性,提高机床生产效率是一种有效的途径。
Study on the assembly accuracy and adoption of effective assembly methods have great significance on the quality assurance of products. This paper introduces assembly techniques and accuracy tests of CKA6150 CNC lathe's headstock throughout the critical final assembly process and provides positional accuracy of the headstock to the bed,inter-relationship between hot and cold accuracy,study and analysis on spindle offset deviation resulting from heat. This assembly technique proves that it is an effective and correct method to ensure the reliability of the entire machine's accuracy and enhance production efficiency during CNC lathe final assembly process on site.
