1、 CA6132 普通车床的数控化改造 摘要 随着现代科技和社会生产水平的不断提高，零件的精度要求越高，要求用于 零件加工的机床有更高的精度和自动化。考虑到机床的生产能力和成本问题，以 旧车床为基础， 通过数控化改造提高机床的占有率是一条节约资金而又快速有效 的方法。本文以 CA6132 作为研究对象，主要研究内容如下。 本文对 CA6132 普通车床的数控化改造进行了深入研究，包括对数控车床结 构的分析、数控车床的改造方案、主传动系统的设计、主轴的形状结构的设计与 计算、主电动机的选择、进给伺服电机的选用、滚珠丝杆的计算与选用。根据机 械、动力学原理，重新设计了车床的主传动系统，使车床实现变频
2、无级调速。结 合车床工作条件加工质量，合理选择滚珠丝杆、齿轮和伺服电机。通过以上的设 计即可实现数控车床的改造，实现要求的技术参数。 关键词：机床占有率 数控化改造 伺服电机 主传动 滚珠丝杆 Numerical control innovation of CA6132 common lathe Abstract：With the continuous improvement of modern science and technology and the level of social production, the higher the accuracy of the parts, the
3、 requirements for the machine tool has a higher precision of parts processing and automation. Considering Machine tool production capacity and cost into consideration, improving machine tool share by numerical control transformation is an efficient and quick way. In this paper, the CA6132 ordinary l
4、athe numerical control transformation was studied. That includes the analysis of the numerical control lathe structure, the retrofit scheme of numerical control lathe, the main drive system design, the shape of the spindle structure design and calculation, the choice of main motor, feed servo motor
5、selection, calculation and selection of ball screw. The main drive system of machine tool was redesigned According to the principle of machinery and dynamics, making makes the lathe realize frequency conversion step less speed regulation. Combined lathe processing quality of working conditions, choo
6、se the ball screw, gear, and servo motor. Design of CNC lathe can be realized through the above reform, realizing technical parameters as required.
