我们在采用经济型数控系统的基础上,开发出数控车床的对刀专用工具——快速对刀器。采用这种对刀器,在数控车床上可对出转位刀架上4～8把刀具的位置尺寸,并能自动将刀尖走到操作者所设定的起始点位置上。一般对4把刀具只需几分钟,而且对刀准确,使用方便。一、对刀器的基本结构及工作原理快速对刀器是由对刀控制程序、标准对刀棒及数控系统的收信接口电路等组成。其基本结构如图1所示。由芯轴、绝缘套、对刀圈所组成的标准对刀棒是作为对刀尺寸基准,并提供对刀信号至计算机,将对刀棒夹在车床的三爪卡盘
Based on the economical CNC system, we developed a special tool for the CNC lathe - quick tooling. Using this pair of knives, CNC lathes on the turret 4 to 8 on the position of the cutter size, and can automatically go to the operator set the starting point on the position. Generally only 4 knives a few minutes, and the knife accurate, easy to use. First, the basic structure of the knife and working principle Fast knife is controlled by the control program, the standard knife bar and CNC system receiving interface circuit and so on. The basic structure shown in Figure 1. By the mandrel, insulating sleeve, the knife against the knife on the standard bar consisting of knife size as a benchmark, and provides the signal to the knife on the computer, the knife will be caught in the three-jaw chuck chuck
