文档介绍：摘要
随着先进制造技术的发展和进步,数控加工已成为机加工过程中的一种主流技术。这一技术的运用提高了机加工过程中工作效率和加工精度。数控多工位钻床就是提高钻削加工精度和效率的一种很好的机加工工具。数控多工位钻床的设计,采用了普通车床设计的步骤和方法,综合考虑数控机床的特点。从切削力入手确定主轴及电机,到整个机床的结构设计和机床的控制,最后到对机床初始化程序设计。本设计是基于多轴加工的普通钻床改造。为了实现复合工位的加工,现需要对普通钻床进行多轴头的设计。普通钻床为单轴机床,但安装上多轴箱就会成为多轴的钻床,改造成多轴钻床后,能大大地缩短加工时间,提高生产效率。因此本设计的重点是多轴箱的设计,设计内容包括齿轮分布与选用、轴的设计、多轴箱的选用、导向装置设计等。

ABSTRACT
With the manufacturing development, numerical control manufacturing has e one of the major advanced technologies. efficiency and accuracy has been improved in application of the technology. Numerical control auto-drilling machine is a kind of the new machine tools that can improve the machining accuracy and efficiency. The paner has designed for Numerical control auto-drilling machine, using design method of the ordinary lathe, and considering the characteristic of the numerical control machine tools synthetically. cutting force has been calculated, the structural and the control system has been designed. Finally, the software routine has been paner has pleted a investigation of internal and external of current situation for numerical control multistage-drilling machine, pared it, put forward a feasible scheme; completed the mechanical structural design an calculated and designed the electric control system, and finished the software and hardware of the control system design is based on the multi-axis machining mon drilling machine. To plish the manufacture of multi-hole, redesigned the drive mechanism of the ordinary drill press. Mono-spindle be changed into a multiple spindle. It will improve its productive efficiency, shorten its processing time if assembled a multiple spindle case on. That so calls a multiple drill. Hereby, the keystone of this design paper is how to design a multiple spindle heads. The design subjects include the selection and distribution of gear wheel, the design of spindle, and the guiding equipment and selection of the multiple spi
