滚丝机是高效螺纹加工机床,它被广泛地应用于机械加工领域。但是,由于该机床上缺乏应有的工件径向定位装置,而是靠操作者手工掌握,使得操作过程中,当两滚丝模接触工件的瞬时,被滚工件的轴线与滚丝模轴线在水平和垂直两个方向上的平行度很难保证,从而造成被滚切后的螺纹中径轴线与工件原来轴线不同轴,以及工件端面与螺纹轴线不垂直。特别是在螺纹长径比较小时,加工中,操作者更不易于手工掌握。为此,我们采用截断机床上方
Thread rolling machine is an efficient thread processing machine, it is widely used in mechanical processing. However, due to the lack of proper radial positioning device on the machine tool, but by the operator manual control, so that during operation, when the two rolling mold contact with the workpiece at the moment, the axis of the workpiece being rolled and rolling mold axis in Horizontal and vertical parallelism in both directions is difficult to guarantee, resulting in being hobbed after the thread diameter axis and the original axis of the workpiece is not coaxial, and the workpiece end and the thread axis is not vertical. Especially in the thread diameter ratio is small, the processing, the operator is more difficult to grasp by hand. To this end, we use truncated machine above
