文档介绍：摘要
随着社会的发展,工业水平的不断提高,加工产品的质量和精度也在不断提高,传统的加工手段只能满足一些的精度的零件,而影响加工精度的一个关键因素就是机床的定位系统,所以定位系统的改进对于一台机床来说,将产生质的变化。
自动冲孔机利用已经成熟的动态摄像技术进行冲孔的准确定位,D照相机获取输出目标的图像信号,由计算机进行图像分析,计算出相应的目标位置并驱动冲头移动至目标正上方。其定位精度高,可实现单孔高精度冲孔,但其拍照和识别范围较小,只能在小范围识别定位,连续作业时仍然需要人工的参与。
为此,本设计根据自动定位冲孔机的这一不足,设计出了一套包含大行程粗定位和小行程精定位的自动进给控制系统,这套系统除了能完成冲孔之外,D相机的连续拍摄自动进给工件,连续打孔,省去了人的参,提高了加工速率。

Abstract
Going with the developing society and the keeping promoting standard of technology, the quality and accuracy of machinery products are improving processing means can only satisfy some parts with lower have a big influence on accuracy is the position system of the machine tool, so a reasonable improvement on the machine tools will makes a big difference.
Automatic punching tool based on the grow up dynamic shoot technology to plish the positioning for means D camera gets the signal of the picture of output objects,then takes it puter for picture analysis and calculates the position of the last,moves the punch to the right above of the target. It provides high accuracy positioning plete single punch with high it can only works well in a small area and needs operator to join.
This design aiming to improve it gives an account of a automatic feeding position system contains big stroke for roughly location and small stroke for high accuracy location. Not only can this plete punching ,but also achieve continuous punching based on the continuous shooting D camera that gets rid of operators and improve the processing efficiency .
