Abstract
A low-power soft starter comprises an electrical cabinet, a resistor, a time relay, a contactor and a connecting wire, wherein the electrical cabinet is fixed behind a drilling machine; the three-phase symmetrical resistor, the time relay and the contactor are fixed in the electrical cabinet; and the wire is connected with the three-phase symmetrical resistor, the time relay, the contact and a spindle motor of the drilling machine. When the low-power soft starter works, a starting key of the drilling machine is pressed, the motor is connected with the three-phase symmetrical resistor in series to start rotating at a low speed, the time relay is powered on, a normally open contact is closed in a time delay manner (the time delay is set at 1-2 seconds), the contactor is powered on and closed, and the motor restores to the normal rotating speed. With the adoption of the low-power soft starter, the transmission gear of the machine can be protected to meet the needs of mass production.
Description
Technical field
The utility model relates to a kind of light duty machine device start field.The small-power soft starting device specifically formed by electric appliance box, resistance, the time relay, contactor, connection wire.
Background technology
Known Z5140, Z5150 vertical lifting bench drill, be the production equipment that does not have the direct rigidity of clutch apparatus to start, and for needing in process of production frequent the parking to change cutter, the production technology of restarting lathe, often damage the lathe travelling gear.Not only increase maintenance cost, affect manufacturing schedule simultaneously, this drawback is never had to good technical scheme and solve.
Summary of the invention
The purpose of this utility model be to provide a kind of invest little, do not change Z5140, the original circuit of Z5150 vertical lifting bench drill, can protect the small-power soft starting device of lathe travelling gear.
For achieving the above object, the utility model small-power soft starting device is comprised of electric appliance box, three-phase symmetrical resistance, the time relay, contactor, connection wire.
Electric appliance box is fixed on to the drilling machine back, and three-phase symmetrical resistance, the time relay, contactor are fixed in electric appliance box, and wire, three-phase symmetrical resistance, the time relay, contactor are connected with the drill press spindle motor.During work, press the lathe start key, the rotation of motor string three-phase symmetrical resistance low rate start, time relay energising, long open contact timing closing (delay adjustments 1 ~ 2 second), the contactor energising is closed, and motor recovers rated speed.
Adopt such small-power soft starting device, its beneficial effect is that investment is little, simple in structure, does not change Z5140, the original circuit of Z5150 vertical lifting bench drill, can protect the lathe travelling gear, meets the needs of producing in enormous quantities.
The accompanying drawing explanation
Fig. 1 is small-power soft starting device structural representation of the present utility model.
1. drilling machine lathe beds in Fig. 1,2. electric appliance box, 3
.three-phase symmetrical resistance, the 4. time relay, 5. contactor, 6. connection wire.
Fig. 2 is small-power soft starting device circuit diagram of the present utility model.
The specific embodiment
Shown in Fig. 1 is small-power soft starting device of the present utility model, electric appliance box 2 is fixed on to drilling machine lathe bed 1 back, three-phase symmetrical resistance 3 is fixed in electric appliance box 2 with the time relay 4, contactor 5, and wire 6 is connected with the drill press spindle motor with the time relay 4, contactor 5 with three-phase symmetrical resistance 3 respectively.During work, press the lathe start key, the 3 low rate start rotations of motor string three-phase symmetrical resistance, the time relay 4 energising long open contact timing closings (delay adjustments 1 ~ 2 second), contactor 5 energisings are closed, and motor recovers rated speed.
Small-power soft starting device circuit diagram of the present utility model shown in Fig. 2, operation principle is: press the lathe start key
→motor M string three-phase symmetrical resistance R
1, R
2, R
3the low rate start rotation
