我厂在S1-127A型管螺纹车床锥度尺的改型设计中,应用直线滚动轴承支承后,在床身上任意位置加工　锥管螺纹。此时,直线滚动轴承7(见图2)分别在滑尺导轨9和靠模尺6上滚动。由于靠模尺调整为一锥度,所以在大托板3纵向运动时,同时伴随着导向板5横向运动,刀架固定在中托架上,中托板 I plant in S1-127A pipe thread lathe taper ruler modified design, the application of linear rolling bearing support, in any position on the bed taper pipe thread processing. At this time, the linear rolling bearing 7 (see FIG. 2) rolls on the slide rail 9 and the scale 6, respectively. As a result of adjusting the ruler to a taper, when the large pallet 3 moves longitudinally, accompanied by the lateral movement of the guide plate 5, the turret is fixed on the bracket, the pallet
