本文所介绍的液压校正装置(附图),采用在车床上,使刀架相对溜板作自动纵向移动,以补偿切削螺纹时传动丝杆所产生的螺距误差。因此,可使切出的螺纹获得 高度的精确性。 如附图所示,溜板借助于由主轴籍经交换齿轮与进 给箱而带动的丝杆A沿导轨移动,进行螺纹切削。切削 螺纹的旋风 The hydraulic correction device described in this paper (with photos) is used on the lathe to make the tool holder automatically move longitudinally relative to the slide to compensate for the pitch error caused by the screw when the thread is cut. Therefore, a high degree of accuracy can be obtained for the cut thread. As shown in the drawing, the slide plate is threadedly moved along the guide rail by means of a screw A driven by the main shaft via the exchange gear and the feed box. Thread cutting whirlwind
