本课题主要研究的内容是针对QKA1219数控管螺纹车床主轴组件部分的设计。设计的主要内容包括确定机床的主要参数，计算和校核主要零部件，并且利用专业制图软件进行零件的设计和处理。另外对一些轴和轴承进行校核，最终利用AutoCAD完成整个设计。根据QKA1219数控管螺纹车床的主要规格和性能要求，先进行主轴箱的总体设计，确定电动机，接着根据传动系统的参数确定主轴结构及尺寸，最后选用轴承并进行相应的校核。从而实现对主轴组件的优化设计。主轴上所选用的轴承既考虑承受径向和轴向载荷，还考虑到了实际生产中主轴受热膨胀伸长的情况。主轴组件中的轴承在满足使用寿命条件下支承主轴转动，保证转动精度。
谁能帮忙翻译一下哈，不要在线翻译的谢啦

Answer 1

This project mainly focus on the investigation of designing main shaft components for numerical control pipe threading machine QKA1219. Main context of this design includes specify main parameters of lathe, calculate and check key components, and take advantage of professional cartographic software to design& handle components. Besides, it includes check and agjust of some shafts and bearings. Finally, use Auto CAD to complete the whole design. According main specificaitons and performance requirements of QKA1219, we start with overall design of spindle box and confirm motor, then we determin structure& dimension of main shaft according to parameter of drive system. At last, choose bearing to do corresponding agjustment thereby finishing optimization design of main shaft components. The selection of main shaft should consider not only radial direction of bearing and thrust load, but also expansion of main shaft during production. Main shaft components support main shaft turning in the condition of assuring useful life to ensure precision of turning.

Answer 2

Main research contents of this subject for a QKA1219 CNC pipe spindle design of a component part. Design a framework for including the identification of main parameters of machine tools, calculation and check of the main parts, and the use of professional graphics software for parts design and processing. In addition to checking the shaft and housing, eventually using AutoCAD to complete the design. QKA1219 CNC pipe main specifications and performance requirements, General design of main spindle box, determine the motor, then according to parameters of transmission system of the spindle structure and size, final selection of the bearing and check accordingly. In order to achieve optimum design of spindle components. Spindle bearing is available in both radial and axial loads, also taken into consideration the actual spindle elongation of thermal expansion in production. Spindle components bearing service life conditions are met by the bearing spindle rotation to ensure rotational accuracy.
