在“鞍钢宪法”的指引下,我厂一车间职工,为了提高阀体螺纹孔的攻丝质量,提高生产效率,减轻体力劳动,用小台钻改装成了一台小型液压攻丝机。这种小型液压攻丝机结构简单,用我厂自制的ZM1-B25液压马达代替台钻上的电机驱动主轴旋转。在台钻的进给齿轮轴上,装有限位开关的控制挡铁,用来控制电磁阀换向。改变液流进入液压马达的旋转方向,达到台钻主
Under the guidance of the “Anshan Iron and Steel Constitution”, workers in the workshop of our factory have improved the production efficiency and reduced manual labor in order to improve the tapping quality of threaded holes in the valve body, and have been converted into a small hydraulic tapping machine using a small bench drill. This kind of small hydraulic tapping machine has a simple structure. The ZM1-B25 hydraulic motor made by our factory replaces the rotation of the motor driven spindle on the bench drill. On the feed gear shaft of the bench drill, a control stop with a limit switch is used to control the solenoid valve reversal. Change the direction of flow into the rotation direction of the hydraulic motor to reach the main driller
