JC01-132@经济型中挡精度数控机床横向进给设计,机械毕业设计全套

内容简介：

摘要 此设计 是 经济型中档精度数控车床 横向 进给 系统 。 面对我国目前机床 数量少 、工业生产规模小的特点，突出的任务是用较少的资金迅速改变机械工业落后的面貌。而 数控车床 （ 及其系统 ） 已经成为现代机器制造业中不可缺少的组成部分。 所以， 实现这一任务的有效的、基本的途径就是普及应用经济型数控机床。 进给系统是由伺服电机经滚珠丝杠拖动工作台来完成的所以设计涉及伺服电机的选择，滚珠丝杠设计等。目前绝大部分的机床的 横向 进给均是采用滚珠丝杠来传递运动的，传动的精确性主要取决于丝杠支承形式，丝杠与伺服电机的联接方式。 在设计中充分考虑 到这两个问题 ，并且 ， 设计精度须达原始数据 。 关键 词 ：滚珠丝杠 伺服电机 横向 进给 ntsAbstract This design is the feeding operation of numerical control lathe with economic type of intermediate precision In view to the quantity of machine tools in our country is not enough and the scale of industrial production is little at present, the outstanding task is to change our mechanical industrial appearance with less fund in short order. And the numerical control lathe and its system have become an important part in modern manufacturing industry. So, to realize this task, the effective and the basic channel is to use this economic type of numerical control lathe widely. Feeding system goes normally with the ball screw which is droved by servo-motor dragging the workbench up and down. So, this design includes the option of servo motor, the design of ball screw and so on.Now, the landscape orientation feeding of most machine tools is offered by ball screw. The accuracy of the transmission depends on mainly the form of the screw supports and the way of how screw and servo-motor to be joined. Besides the precision of the design needs Bases the primal data. Consider these two questions in the design s
