摘 要

  在本次设计中,我采用常规分离式主传动设计,机床主传动采用液压操纵机构,可实现十八级转速。机床主轴为二支撑结构,前支撑采用C级高精度轴承,润滑油润滑,提高了回转精度,使机床主轴具有良好的精度和刚性。

  进给方面,采用开环数控系统。采用步进电机开环数控系统已基本能满足进给精度的要求。数控系统采用单片机技术在总体性能上可以达到经济精密数控机床之列,达到较好的性价比。

  我们采用磁刹车离合器。机床两轴进给系统采用步进电机驱动滚珠丝杠的典型传动方式,在滑板与床鞍及床鞍与床身之间的滑动面处贴有TSF导轨板,滑动磨擦系数非常小,有助于提高了机床的快速响应性能及生产效率。机床采用立式四工位刀架。

  该机床可以加工各种轴类、盘类零件,可以车削各种螺纹、圆弧、圆锥及回转体的内外曲面。作为通用型机床,特别适合汽车工业、摩托车行业、电子工业、航天、军工等行业,对旋转体类零件进行高效、大批量、高精度加工时采用。车床采用机、电、液综合运用。该机床整体设计符合国家标准。该机床能加工精度相对较高的工件。

Abstract

 In this design, I have split the main using conventional design, Lathes the lord spread to move to adopt the liquid to press to manipulate the organization, and can realize 18 classes turn soon. Lathes principal axis is two prop up the construction, and before prop up to adopt the high accuracy bearings of C class, grease, and improved precision rotary, and so that the machine spindle has a good accuracy and rigidity.

 I adopt using open-loop CNC system in Feed aspects . Using open-loop stepper motor CNC system has been basically able to meet the requirements of precision feed. Numerical control system uses microcontroller technology.Performance can be achieved in the overall economy of the column precision CNC machine tools to achieve better cost performance.

 We use the monolithic electromagnetic brake clutch.Lathes two stalks enter the system to adopt the step the glide for typical model for entering the electrical engineering drive recirculating-ball screw spreading moving the way, among the skateboard and bed saddle and bed saddle and bed body to stick to have the TSF guide plate,lide coefficient of friction very small, is beneficial toed to increase the Lathes of quickly respond to the function and produce the efficiency.We adopt vertical 4-position turret

The machine can process a variety of shaft ,disk types.It also can cut all kinds of thread、arc、cone、and rotary inside and outside of the body surface. Lathes adopt mechanical, electrical and hydraulic integrated. The overall design of the machine is in line with national standards.The machine can be a relatively high machining precision parts.
