Description
Technical field
The utility model relates to a kind of electric device, relates in particular to a kind of curb girder electric device of welding automatically that is used for.
Background technology
Wire feed dolly crude oil is driven by motor in the curb girder automatic soldering device, and must have two oil pipes to follow the wire feed moving of car this moment, and oil pump is placed on ground and will works always, easily overload.Oil motor speed can not be regulated, and oil pipe moves back and forth fragile, can cause accidents such as leakage of oil.
Summary of the invention
The technical problem that the utility model will solve is: wire feed dolly crude oil is driven by motor in the curb girder automatic soldering device; Oil motor speed can not be regulated; Oil pipe moves back and forth fragile, can cause accidents such as leakage of oil, and a kind of curb girder electric device of welding automatically that is used for is provided.
In order to overcome the defective that exists in the background technology; The utility model solves the technical scheme that its technical problem adopted: this electric device that is used for the automatic welding of curb girder comprises controller PLC; The output point Q14 of said controller PLC connects D.C. contactor KMZ1; The output point Q15 of said controller PLC connects D.C. contactor KMZ2; Said D.C. contactor KMZ1 is connected DC servo motor control power supply A1 with D.C. contactor KMZ2 through interface H1; Said D.C. contactor KMZ2 connects DC servo motor control power supply A1 through interface H2, and the interface VR1 on the said DC servo motor control power supply A1 is connected potentiometer R1 with interface VR2, and the interface 4 on the said DC servo motor control power supply A1 is connected indicator lamp HL1 with interface 5; Interface 2 on the said DC servo motor control power supply A1 connects fuse F U1, and said fuse F U1 connects low-voltage circuit breaker QF1.
The beneficial effect of the utility model is: this simple in structure of the automatic electric device that welds of curb girder that be used for, and the wire feed dolly is driven by DC servo motor like this, can regulate, and oil pipe is not fragile.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the structural representation of the utility model PLC controller.
The specific embodiment
As depicted in figs. 1 and 2; Among Fig. 2 controller PLC; The output point Q14 of said controller PLC connects D.C. contactor KMZ1, and the output point Q15 of said controller PLC connects D.C. contactor KMZ2, and is as shown in Figure 1; D.C. contactor KMZ1 is connected DC servo motor control power supply A1 with D.C. contactor KMZ2 through interface H1 among the figure; Said D.C. contactor KMZ2 connects DC servo motor control power supply A1 through interface H2, and the interface VR1 on the said DC servo motor control power supply A1 is connected potentiometer R1 with interface VR2, and the interface 4 on the said DC servo motor control power supply A1 is connected indicator lamp HL1 with interface 5; Interface 2 on the said DC servo motor control power supply A1 connects fuse F U1, and said fuse F U1 connects low-voltage circuit breaker QF1.
Supply with DC servo motor control power supply A1 AC power 220V through low-voltage circuit breaker QF1 and fuse F U1.Low-voltage circuit breaker QF1 plays on-off action, can also be used for electrical overloads, short-circuit protection.Fuse F U1 is used for electrical overloads, short-circuit protection.DC servo motor control power supply A1 is connected with DC servo motor M1.When programmable controller PLC output point Q14 connected D.C. contactor KMZ1, coil got electric, and its contact is connected, the energising of DC servo motor M1 magnet exciting coil forward, the running of motor forward; When programmable controller PLC output point Q15 connects D.C. contactor coil KMZ2, and must be electric, its contact is connected, and DC servo motor M1 magnet exciting coil is oppositely switched on, the motor antiport.Through regulator potentiometer R1, can regulate DC servo motor M1 running speed.Write programmable controller PLC program according to technological requirement and realize control DC servo motor M1.Indicator lamp HL1 is bright during DC servo motor M1 operation.Like this, the PLC programmable controller was controlled the part of oil motor originally, changed control D.C. contactor KMZ1 and D.C. contactor KMZ2 coil into, and then control DC servo motor M1.
This simple in structure of the automatic electric device that welds of curb girder that be used for, the wire feed dolly is driven by DC servo motor like this, can regulate, and oil pipe is not fragile.
