To achieve these goals; The technical scheme that the utility model adopts is: a kind of rack automatic arc welding electric control system, comprise external control device, main motor, auxiliary-motor, hydraulic pump and welding gun, and also comprise PLC controller, welding machine control circuit, A.C. contactor A, A.C. contactor B, A.C. contactor C, speed adjusting plate, sensor sum counter; The external control device is connected with the PLC controller; The PLC controller is connected with counter, speed adjusting plate, A.C. contactor A, A.C. contactor B, A.C. contactor C and welding machine control circuit respectively, and counter is connected with sensor, and speed adjusting plate is connected with main motor; A.C. contactor A is connected with main motor; A.C. contactor B is connected with hydraulic pump, and A.C. contactor C is connected with auxiliary-motor, and the welding machine control circuit is connected with welding gun.
Wherein, the PLC controller is connected with main motor through voltmeter.
Speed adjusting plate is provided with the speed display list, and speed adjusting plate is connected with the speed display list.
The beneficial effect of the utility model is: simple to operate, easy to use, and the welding precision of raising welding machine, saving workman's muscle power improves work efficiency of workers effectively.
Description of drawings
Fig. 1 is the electric theory diagram of the utility model.
The specific embodiment
To combine accompanying drawing that the utility model is described further below.
As shown in Figure 1, a kind of rack automatic arc welding electric control system comprises external control device, main motor, auxiliary-motor, hydraulic pump and welding gun; Also comprise PLC controller, welding machine control circuit, A.C. contactor A, A.C. contactor B, A.C. contactor C, speed adjusting plate, sensor, voltmeter, counter and speed display list; The external control device is connected with the PLC controller, and the PLC controller is connected with counter, speed adjusting plate, A.C. contactor A, A.C. contactor B, A.C. contactor C, voltmeter and welding machine control circuit respectively, and voltmeter is connected with main motor; Counter is connected with sensor; Speed adjusting plate is connected with main motor with the speed display list respectively, and A.C. contactor A is connected with main motor, and A.C. contactor B is connected with hydraulic pump; A.C. contactor C is connected with auxiliary-motor, and the welding machine control circuit is connected with welding gun.
The course of work: the PLC controller receives the signal that the external control device transmits, and the PLC controller is controlled main motor through A.C. contactor A, thus the control that realization is just changeed/reversed main motor; The PLC controller is through A.C. contactor B control hydraulic pump, thus the up-down of realization control ram; The PLC controller is through A.C. contactor C control auxiliary-motor, thereby the realization auxiliary-motor is controlled the forward/backward of secondary cabinet; The PLC controller is through welding machine control circuit control welding gun, thus realize welding gun begin to weld/stop welding, the receipts arc that the while can Butt welding gun is controlled; The PLC controller is controlled main motor through speed adjusting plate; Realization is to the adjusting of the velocity of rotation of main motor; PLC is connected through voltmeter and main motor; Realize the voltage condition of the main motor of monitoring, can understand main rotating speed of motor in real time, the user can understand current main rotating speed of motor in real time through the speed display list simultaneously; Sensor passes to counter with detected main motor revolution signal; Counter is counted; Simultaneously signal is passed to the PLC controller, when reaching the counter setting value, the PLC controller is controlled main motor and is quit work; So just can realize arriving preset rotation numerical, the electric welding function quits work automatically.
