在常规情况下,普通车床只能加工等螺距丝杠。我们对普通车床C6250改装后,就可以方便地加工变距丝杠了。图1是要加工的变距丝杠,它是麻织机械中的关键部件之一。在纵向走刀运动和工件回转运动两者都为等速的情况下,另将走刀丝杠回转运动经辅助的组合机构(由蜗杆、蜗轮-凸轮-齿条-齿轮组成)变换后,通过尾座芯轴施加在工件上,从而使工件在纵向产生附加的等加速移动。其传动部分如图2。图中花键套与装夹在主轴上的套(法兰)固结,主轴转动时,经花键套和花键轴及卡盘驱动工件回转。走刀丝杠带动刀架产生等速的
Under normal circumstances, ordinary lathe can only process such as pitch screw. We modified the general lathe C6250, you can easily process variable pitch screw. Figure 1 is to be processed pitch screw, it is one of the key components in the linen machinery. In the case of both longitudinal and workpiece turning movements at constant speed, the turning movement of the take-over lead screwdriver is converted by the combined mechanism (consisting of a worm, a worm gear, a cam, a rack and pinion) Tailstock mandrel is applied to the workpiece, so that the workpiece in the longitudinal direction of the additional isochronous movement. The transmission part shown in Figure 2. In the figure, the spline sleeve is fixed with the sleeve (flange) mounted on the spindle. When the spindle rotates, the spline sleeve and the spline shaft and the chuck drive the workpiece to rotate. Take the knife lead screwdriver to produce constant velocity
