C620车床经过长时间使用后,开合螺母的刹铁在使用中会产生磨损,导致开合螺母与刹铁之间的间隙增大,原设计是由三颗调整螺钉来消除这个间隙的,但是我们往往忽视了对它的调整,造成车螺纹时扎刀或乱扣现象。起初我们误认为是开合螺母的磨损造成的,甚至经过多次调整限位销,仍然消除不了扎刀和乱扣。开合螺母刹铁间隙的调整方法(附图)是:松开锁紧螺母3,按顺时针方向旋转调节螺钉4,当认为开合方便、工作时稳
C620 lathe after a long time use, opening and closing nut brake iron will be worn in use, leading to opening and closing nut and brake the gap between the increased iron, the original design is to eliminate the gap by the three adjusting screws, but We often overlook the adjustment of it, resulting in the car thread or knife buckle phenomenon. At first we mistakenly thought that the opening and closing nuts caused wear and tear, and even after adjusting the limit pin several times, still can not eliminate the knives and chaos buckle. Opening and closing nut brake iron clearance adjustment method (with photos) is: Loosen the lock nut 3, clockwise rotation of the adjustment screw 4, when that opening and closing convenient, stable work
