我们在JT4542机械动力滑台的电气回路里,增加两个交流接触器,克服了滑台工作终了时偶尔控制失灵的问题,同时进一步提高了滑台终点的定位精度,取得了较理想的效果。 JT4542机械动力滑台配置主轴箱加工带止口的孔时,适合采用带反向进给的机床动作。其工作循环为:快进-工进-工退-快退。滑台移动有两个电机,一个快速电机、一个工进电机。电气原理如图1 We JT4542 mechanical power slide in the electrical circuit, the addition of two AC contactor to overcome the slip of the occasionally occasional control failure at the end of the work, and further improve the positioning accuracy of the end of the slide, and achieved satisfactory results. JT4542 mechanical power slide configuration headstock machining hole with a hole, suitable for use with reverse feed machine action. The working cycle: fast forward - work - work back - rewind. The slide moves two motors, a fast motor, and a work-in motor. Electrical principle shown in Figure 1
