在车床上攻丝,用手动操作的一般方法是:先将丝锥头部放入螺纹底孔中,用活板手夹住丝锥的方榫部,将板手柄部放于车床导轨上。开车,正转进行攻丝,反转时用手握住板手,退出丝锥。如果手的力量小,握不住容易出事故。我们在生产实习中尝试了一种新的方法。就是将板手固定于刀架上,按所攻的螺距调整好车床各手柄位置,按下开合螺母,使板手和丝锥实现同步运动。 Tapping in the lathe, the general method of manual operation is: first tap the head into the bottom hole of the thread, with live hands clamped tap tenon, the handle part of the plate on the lathe rail. Drive, forward to tapping, hand holding the wrench when reversing, exit the tap. If the hand’s power is small, it can not hold out easily. We have tried a new method in production internship. Is the wrench is fixed to the knife holder, according to the pitch of the pitch to adjust the lathe handle position, press the opening and closing nuts, so that the wrench and tap synchronized movement.
