立式铣床主轴及铣头结构设计〔三维建模CAD图纸〕

摘要

随着制造业的开展,高速度、高效率、高精度和高刚度已经成为当今机床发

展的主要方向。为了满足当前机床市场的需要,铣床已经成为了当今机械行

业一

个重要的开展趋势,特别是在工业制造,加工过程中有着举足轻重的地位。在

各

式各样的机床中,立式铣床有着独特的加工对象。主要是对大型的平面、沟

槽等

进行铣削。在对铣床的研究中到达了一定的水平,从而铣床的主要配件立铣

头的

研究在一定程度上也到达了空前的规模。通过以往的加工经验可以对立铣

头的研

究在一定程度上有所改良,铣床主轴是靠齿轮进行传动的。铣床铣头的转动

方式

有多种多样,每种机床铣头的形式都不尽相同。立铣头的传动方式也是多

种多样,

立铣头主轴传动系统采用齿轮传动,传动形式采用集中式传动,主轴变速系

统采

用多联滑移齿轮变速。齿轮传动具有传动效率高,结构紧凑,工作可靠、寿命

长,

传动比准确等优点,齿轮机构是现代机械中应用最广泛的传动机构,用于传

递空

间任意两轴或多轴之间的运动和动力。现在的工业开展对铣削有了更加苛

刻的要

求,高精度、高速度、高效率、复合型、智能型等是今后开展的主要趋势。
