摘要
十字轴加工过程中,既要控制同轴轴头的同轴度≤0.015mm,又要控制相互垂直的二组轴的垂直度≤0.025mm。采用传统的四次装夹,分别钻中心孔和车削轴头的工艺,难以保证加工精度。为了提高加工精度,须减少加工过程中的装夹次数,基于CJK6136型数控车床,将原有的液压卡盘改造成液压自动分度卡盘,普通车床尾架改造成液压驱动尾架,进行二次开发,设计了十字轴"一次安装完全加工"的全自动专用机床,提高加工效率近10倍,保障了工艺精度,拥有开发成本低的优势。
In cross-axis machining processing it is necessary to control the coaxial shaft concentricity ≤ 0. 015mm, and also control two groups of mutually perpendicular axes vertical ≤0. 025mm, using the traditional need four clamping, respectively, the center hole and drill turning shaft of the process, but it is difficult to ensure accuracy. Based CJK6136 CNC machine, through the transformation of the original hydraulic chuck, hydraulic control quick drive to increase the end frame, the second development, the design of the cross axis ＂ a complete installation process,＂ the fully automatic machine tools, improve the processing efficiency nearly 10 times the protection of the process accuracy, has the advantage of lower development costs.
