防爆电机机座车削用液性塑料芯轴研究与设计

Research and Design of Liquid Plastic Mandrel Used in Explosionproof Motor Frame Turning

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 the type of production of the explosion-proof motor frame, this paper studies and determines it＇s main mechanical processing method, identifies the positioning program and the clamping way of the fixture based on the study of the fixture design principles. In this thesis, the analysis of the positioning error, the formula, compounding and pouring of the liquid plastic, the design of the thin sleeve and plunger, and the clamp specific designing etc. are also studied systematically. Meanwhile, the liquid plastic mandrel used in the explosion-proof motor frame turning is engineered completelly. That provides reliable guarantee to the improvement of the frame machining precision.
