摘 要

数控技术是制造业实现自动化、柔性化、集成化生产的基础，现代的CAD/CAM、柔性制造系统、计算机集成制造系统等等，都是建立在数控技术基础之上的。同时，数控技术也关系到国家战略地位，是体现国家综合国力水平的重要基础性产业因素之一，其水平高低是衡量一个国家制造业现代化程度的核心标志。实现加工机床及生产过程数控化，已成为当今制造业的发展方向。推广与应用数控技术是我国机械制造行业的一项重要的战略任务。数控机床的生产准备的时间短，所制造的零件重复精度高，对改变零件设计的适用性强，夹具成本低，加工形状复杂的零件时准确可靠。因此，数控机床在现阶段以及以后的时间将占据重要地位。

本题目是数控车床CK6163的纵向进给系统设计。首先根据典型工艺数据，结合拟定参数，传动方案的确定。对传动系统主要结构进行设计，包括选择滚珠丝杠螺母副和减速箱体的机构设计，从而完成整个进给系统机械结构的设计。然后，通过计算选择步进电机，驱动滚珠丝杠运动，从而带动工作台运动。基于AT89C51对步进电机的控制系统设计，使电机实现正反转，快速正反转功能，保证对传动系统的控制要求，从而完成整个进给系统的设计。

Abstract

Numerical control technique is the basic of automation, flexible, integrated, production in manufacturing, modern CAD/CAM, flexible manufacturing systems, computer integrated manufacturing systems are all built on the basic of numerical control technology. At the same time, numerical control technique is related to the strategic importance of a country and it is one of the important foundation industries to reflect the overall national strength of a country, the level of which is the core signs of measuring the modernization of a country’s manufacturing. The realization of the processing of CNC machine tools and production processes has become the development direction of the manufacturing. Popularizing and using numerical control technology is a strategic task in our mechanical manufacturing industry. NC machine tools, which can produce parts with high repeated precision and manufacture complex shape parts with reliability, need no more time to prepare, have more flexibility to alteration of parts, and clamping apparatuses of NC machine tools are very simple. Consequently, NC machine tools will play an important position in mechanical manufacturing at now and a period of time in the future.

The topic is the design of CK6163 vertical feed system. First of all, the solution of transmission will be determined according to the typical technological data and combined with the formulation parameters. Design the main structure of the transmission system, including choice the ball screw and design the structure of the slowdown box, so as to complete the design of mechanical structure of the whole system. Then, choice the stepping motor by calculating, drive the ball screw, which led campaign table. In order to complete the design of feeding system, design the control system of stepping motor based on AT89C51, so that the motor to achieve positive or negative rotating, rapid positive or negative rotating, ensure the control of the transmission system.

Key words: CNC machine tools；ball screw；stepping motor；single-chip
