根据防爆电机机座的结构、技术要求和生产类型,研究并确定了防爆电机机座的主要机械加工工艺方法。在研究了夹具设计原理的基础上,确定了夹具的定位方案与夹紧方式,详细研究了定位误差的分析,液性塑料的配方、配制和浇注,薄壁套筒及柱塞的设计,夹具体设计等内容,设计了机座车削加工过程中所用液性塑料芯轴,为提高机座加工精度提供可靠保证。
According to the structure, technical requirements and production type of explosion-proof motor base, the main mechanical processing technology of explosion-proof motor base is researched and determined. Based on the study of the principle of the fixture design, the positioning scheme and clamping mode of the fixture are determined. The analysis of the positioning error, the formulation of the liquid plastic, the formulation and pouring, the design of the thin-walled sleeve and the plunger, Specific design and other content, designed the liquid plastic mandrel used in the lathe turning process, to provide a reliable guarantee for improving the machining accuracy.
