在锅炉集箱上排列着许多圆孔,用摇臂钻床加工的突出问题是劳动强度大,加工周期长,精度不易保证。为此,我们研制了单板机控制的集箱专用钻床。一、系统简介 1.机床简介该机床由床身、动力头、液压夹具三部分组成。床身长6米,动力头由3台交流异步电机拖动,完成位移、定位、打孔等操作。工件由液压夹具夹紧。 2.定位原理微控钻床是典型的点位控制系统,准确实现定位控制是对该系统最基本的要求。本控制采用绝对坐标,床身上的零位开关作为坐标原点。控制方式是半闭环控
Many round holes are arranged on the header of the boiler. The outstanding problems of processing with a radial drilling machine are that labor intensity is large, the processing period is long, and the accuracy is not easily guaranteed. To this end, we have developed a single machine-controlled header dedicated drilling machine. First, the system profile 1. Introduction to the machine The machine consists of bed, power head, hydraulic fixture composed of three parts. Bed length 6 meters, powered by three AC asynchronous motor drag to complete the displacement, positioning, drilling and other operations. Workpiece is clamped by hydraulic clamp. 2. Positioning principle Micro-controlled drilling is a typical point control system, accurate positioning control is the most basic requirements of the system. The control of absolute coordinates, the bed of the zero switch as the origin of coordinates. The control method is semi-closed loop control
