传统摇臂钻床的改造方案

国产的摇臂钻床(如图)是使用较为广泛的普及型产品之产品间的零部件通用化程度较高,从控制上讲,需机、电、液压等相配合而且要进行时间控制。具有主轴的旋转运动和进给运动以及摇臂沿外立柱的垂直移动,主轴箱沿摇臂的径向移动及摇臂与外立拄一起相对于内立柱的回转运动:后两者为手动。另外还需考虑主轴箱、摇臂以及内外立拄的夹紧和松开。因此相应电动机较多,电路较复杂,往往因电气故曈而影响生产的进行。

摇臂钻床

机床从电动机控制方法的角度来说,自简单的分级调速发展到变频调速,再到现在的伺服控制;从控制系统的角度来说,自简单的孚动操作到电子化的升级,现在又发展到数控产品,控制功能越来越完善。但甶于数控系统成本很高,用在摇臂钻床上不仅大材小用,且随看制造成本的增加会使产品的性价比大幅降低。因此电子化摇臂钻床是取代普通摇臂钻床的最佳改造方案。利用可编程逻辑控制器(简称PLC)和变频器进行局部改造:彻底更换电气系统,改造成具有速度显示、进给选择、变频主轴等功能的电子摇臂钻床。这样不但能显著提高摇臂钻床的工作效率和稳定性,还可以直观地显示机床的工作状态,方便用户的操作。

 

Transformation scheme of traditional radial drilling machine

The domestic radial drilling machine (as shown in the figure) is a popular product widely used. The parts of the products have a high degree of generalization. From the control point of view, it needs the coordination of mechanical, electrical and hydraulic pressure, and time control is required. It has the rotation and feed movement of the spindle and the vertical movement of the rocker arm along the outer column, the radial movement of the headstock along the rocker arm and the rotary motion of the rocker arm and the outer column relative to the inner column: the latter two are manual. In addition, the clamping and loosening of headstock, rocker arm and inner and outer pillars should be considered. Therefore, there are many corresponding motors and complicated circuits, which often affect the production due to electrical faults.

From the perspective of motor control method, machine tools have developed from simple step-by-step speed regulation to variable-frequency speed regulation, and then to the present servo control; from the perspective of control system, from simple motor operation to electronic upgrading, and now to CNC products, the control function is more and more perfect. However, the cost of CNC system is very high, so it is not only overused in radial drilling machine, but also the cost performance of products will be greatly reduced with the increase of manufacturing cost. Therefore, the electronic radial drilling machine is the best transformation scheme to replace the ordinary radial drilling machine. The PLC and frequency converter are used for local transformation: the electrical system is completely replaced, and the electronic radial drilling machine with the functions of speed display, feed selection and variable frequency spindle is transformed. This can not only significantly improve the working efficiency and stability of the radial drilling machine, but also visually display the working state of the machine tool, which is convenient for users to operate.
