29. Electrical control principle (with circuit diagram)
QF0 is the machine tool power switch. SB1 and SB2 are emergency stop buttons. The power indicator light is on to indicate that the main power switch is on; the overload indicator light is on to indicate that a motor is o verloaded. The corresponding circuit breaker has cut off the control power and all the motors have stopped running. B 3, SB5 , SB7 , SB9 , and SB 11 are the start buttons of each tool axis, respectively, and the start buttons have indicator l ights. SB 4 , SB6 , SB 8 , SB 10 , SB 12 are the stop buttons for each tool axis. SA is the selection knob of the feeding method. The knob has two working positions, one is jog feeding and the other is continuous feeding. The continuous mode has a self-locking function. In the continuous mode, the feeding state can only be released by pressing the "stop feeding" button. Return can only be jogged. The li fting of the feed roller works in a jog mode. SB16 and SB17 are the up and down buttons of the feed roller. The beginning of the stroke SQ1, SQ2 and SQ3 are designed to ensure that the feed roller does not exceed the stroke and does not touch the device when it is raised or lowered.
