CPQ-1型叉车变速箱体加工工艺及双面钻孔组合机床主轴箱设计
摘要
本主要说明组合机床设计的基本过程及要求。组合机床是按高度集中原则设计的,即在一台机床上可以同时完成同一种工序或多种不同工序的加工。组合机床发展于工业生产末期,与传统的机床相比:组合机床具有许多优点:效率高、精度高、成本低。它由床身、立柱、工作台、及电源一些基本部件及一些特殊部件,根据不同的工件加工所需而设计的。
在组合机床上可以完成很多工序,但就目前使用的大多数组合机床来说,则主要用于平面加工和孔加工两大类工序。主要内容包括四大部分:
(1)、制定工艺方案。通过了解被加工零件的加工特点、精度和技术要求、定位夹紧情况、生产效率及机床的结构特点等,确定在组合机床上完成的工艺内容及加工方法,并绘制被加工零件工序图。
(2)、组合机床的总体设计。确定机床各部件之间的相互关系,选择通用部件和刀具的导向,计算切削用量及机床生产效率、绘制机床的尺寸联系图及加工示意图。
(3)、组合机床部件设计。包括专用多轴箱的设计,传动布局合理,轴与齿轮之间不发生干涉,保证传动的平稳性和精确性。专用主轴设计、轴承的选用及电机的选择等。
(4)、液压装置的设计。液压滑台、定位夹紧装置均为液压控制。并采用了许多液压控制阀,保证了运动的平衡性,循环性和精确性。
