我厂利用C630车床铸坯,改制了一台能车能磨的土设备(图1),解决了以前无设备修复曲轴轴颈和进行大件车削的难题.它能修磨各种曲轴,几年来共修复曲轴1500余根,修磨后曲轴颈的椭圆度与锥度均在0.005毫米左右,符合大修技术要求,使用效果较好.现就这台土设备在车床的基础上进行改进和新增的部分介绍如下,供参考. 机床的组成一、床头箱床头箱是按C630车床图纸加工的,其结构主要改 I plant using C630 lathe slab, the restructuring of a car can be able to grind the soil equipment (Figure 1), to solve the previously no equipment repair crankshaft journal and large turning problem.It can grind a variety of crankshaft, a few Over the years a total of more than 1,500 crankshaft repair, after grinding crankshaft ellipticity and taper are about 0.005 mm, in line with overhaul technical requirements, the use of better. Now on this soil equipment in the lathe on the basis of improvement and new Part of the introduction are as follows, for reference. The composition of a machine, bedside box headstock is processed by the C630 lathe drawings, the structure of the main changes
