钻床主轴进给机构改造变速机构本科大学毕设论文

摘 要随着先进制造技术的进展和进步，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。本文对数控多工位钻床进行了设计，采纳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。本文完成数控多工位钻床的资料收集与国、内外现状的调查比较，提出较为可行的方案;完成机床的机械结构设计计算与电气控制系统设计，初步完成控制系统的软硬件设计。本设计是关于将普通钻床改造为多工位加工钻床的结构设计。普通钻床为单轴机床，且工件安装后需要进行反复调整，工件上有相互位置要求的各表面间的位置精度就会受到很多因素的影响，通过设计改造成快速主轴、移动工作台和具有一定回转精度的能实现多工位加工的钻床后，能大大地缩短加工时间，提高生产效率。因此本设计主要从钻床的主轴箱设计、移动工作台设计及工作台的回转设计几个方面，对普通钻床进行一定的结构改进，实现多工位加工，以符合现代机械加工的要求。关键词：多工位钻床；生产效率；主轴箱AbstractWith 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...
