我厂工具科电工小组,在1A62型车床上增加一个断电联动装置,可以使机床电动机随机床的停车而停止运转,一台机床一年可为国家节约电力2403瓩。联动装置很简单。在走刀箱旁的停车手柄的连杆上装一个凹圆弧轮,凹弧轮的圆弧应和直线开关的接点紧密接触。停车时,搬动手柄,凹弧轮和活动接点紧密接触,直线开关内的电键和电路分开,切断电路,电动机停止转动。开车时,搬动手柄,这时凹弧轮和活动接点脱开, I Electric Tools Group Branch Division, in the 1A62 lathe to increase a power linkage, the machine can stop the motor bed random operation, a machine a year for the country to save electricity 2403 瓩. The linkage is simple. A concave circular arc wheel is mounted on the connecting rod of the parking handle beside the knife box. The arc of the concave arc wheel should be in close contact with the contact of the linear switch. Parking, moving handle, concave arc wheel and movable contact in close contact, the linear switch within the key and circuit separate, cut off the circuit, the motor stops rotating. When driving, move the handle, when the concave arc wheel and movable contact disconnect,
