摘要
本次毕业设计课题是CJK6032简易数控车床。该数控车床结够简单,紧凑、体积小,功能齐全,是一个很适用的经济性数控车床,能够达到非常满意的工作效率。
CJK6032主要是由传动系统,进给系统和控制系统三部分组成。对其传动系统设计时,先进行总体方案的确定,画出简易的传动系统图。再根据给定的设计参数来确定传动和进给系统。滚珠丝杠由步进电机来驱动,步进电机由驱动控制系统来驱动。从而实现进给系统的进给。通过用途,功能和技术要求等合理定出系统结构,并通过认真的计算得到的参数,然后选择符合规定的元件和进行系统的结构设计。CJK6032是无级调速的,由电动机加变频器来实现。最后通过技术经济分析,验证了设计生产该产品是经济合理的。

ABSTRACT
The subject of design is the simple NC CJK6032-lathe. The numerical control lathe pact,small size, fully functional,is a suitable economy C lathes. we can achieve a satisfactory work efficient.
The simple NC CJK6032-lathe posed of drive system, feed system and controlsystem. When designing drive system, the diagram of simple drive system are the drive and feed system are designed according to the given design parameter. Thefeed system is working with the assistance of ball screw. The steped motor drove by deivecontrol system is drove by ball screw. through the use of functional and technical requeirements set reasonable structure,and through careful calculation by the parameters,and then select the ponents and systems for the structural simple NC CJK6032-lathe has variable speed which is plished by motor and frequency converter. In the end, the analysis on economic prove its reasonable to produce to CJK6032-lathe.
Key words:Lathe;Ball Screw;Stepping motor;Variable Speed;Transmission system
第1章绪论
数控车床利用数字化的信息对车床运动及加工过程进行控制,是一种可编程的通用加工设备,能自动完成内外圆柱面、圆锥面、圆弧面、端面、螺纹等工序的切削加工,所以特别适合加工形状复杂的轴类和盘套类零件。与通用机床和专用机床相比,数控车床具有加工灵活、通用性强、能适应产品的品种和规格频繁变化的特点,能够满足新产品的开发和多品种、小批量、生产自动化的要求,是一种柔性的、高性能的自动化车床,代表了现代控制技术的发展方
