机械专业多工位数控钻床设计毕业论文

【摘要】本文要紧针对形状相对复杂的工件的孔加工工件，现在一样都采纳钻床加工，但随着科技的进展和对制造精度有了更高的要求，因此数控技术成为了主流。而数控多工位钻床确实是提高钻削加工精度和效率的一种专门好的机加工工具，在满足制造精度的前提下，更是节约了人力、时刻的成本。

在一样情形下，数控钻床就满足需求，而基于采纳西门子数控系统，能完成连续精确的高速钻孔。相关于传统的数控钻床，该方案能适合较大直径的深孔加工，且还满足加工速度、高精度、高生产效率的要求;

运动方式而采纳点位操纵系统，先以较快速度移动到终点邻近位置，再以低速正确移动到终点定位位置，保证了良好的定位精度；

而操纵方式那么采纳半闭环操纵系统，该系统通过检测移动部件的位置，然后反馈到数控装置的比较器中，与输入的原指令位置进行比较，用比较后的差值进行操纵，是移动部件补充位置，直到差值交出为止，因此增大了工件的加工精度；

Design of CNC drilling machine with multi-position progressive die

【Abstract】This article which mainly aimed at the shape of the hole of the work pieces those relatively complicated process work pieces. At present，the drilling machine processing have been typically used, but with the development of science and technology and manufacturing precision need the higher request. The numerical control technology became the mainstream. And the numerical control of progressive drilling machine is a kind of very good machining tool to enhance drilling processing precision and efficiency. It not only meets manufacturing precision, but also low the manpower and the time.

Usually, The Numerical Control Drilling Machine will meet the demands, and the numerical control system based on Siemens’, it can do high speed drilling and accuratel y. Compared with the traditional Numerical Control Drilling Machine, it’s suitable for some larger diameter and deep hole processing, and still meet the requests of speed, high precision, high production efficiency requirements.

The Position Control System will take care of the mode of motion. Firstly, in a rapid rate moves to the near position of the end. And it with a low speed to the correct end position. To ensure it can be in the good location accuracy.

And control the half-closed-loop control system, by detecting the position of the moving parts of the system, and then back to the comparison of the numerical control device, and enter the location of the original instructions, control difference compared, is moving parts added, until the difference until the surrender, thus increasing the precision of workpiece machining

【Key words】Precision, Numerical Control Technology, Multi-station, Drilling
