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。Abstract
With the manufacturing development, numerical control manufacturing has become 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 explored.This paner has finished completed a investigation of internal and external of current situation for numerical control multistage-drilling machine, and compared 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 tentatively.The design is based on the multi-axis machining of common drilling machine. To accomplish 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 spindle heads, etc.
Key words: multi-position manufacture; multiple drill press; productive efficiency; multiple spindle heads
