本文根据公司目前实际镗床精度情况,介绍了在普通镗床上同镗转轮体传统的工艺方法,分析其产生叶片大小轴孔同轴度误差的原因。在减轻数控镗床负荷的情况下,充分利用普通镗床自身带的滑块可以镗削大于1000的轴孔的优势,将转轮体叶片大小轴孔分别单独镗削,圆满解决了转轮体叶片大小轴孔同轴度及叶片大小轴孔轴心线与止推面不垂直的难题,保证了转轮体与叶片一次装配成功。
Based on the actual boring machine precision of the company, this paper introduces the traditional process of the same boring wheel on the ordinary boring machine, and analyzes the reason of the error of the concentricity of the shaft hole with the size of the blade. In reducing the burden of CNC boring machine, make full use of ordinary boring machine with its own slider can be boring more than 的 1000 axis hole advantages, the size of the rotor blade shaft hole were boring separately, the successful solution to the rotor blade The size of the axial hole axis and the size of the axis of the shaft hole axis and the thrust surface is not vertical problem, to ensure that the rotor body and blade a successful assembly.
