The problems of power supply, air supply and hydraulic supply of automatic screw tightening machine often lead to the failure of automatic equipment. For example, power supply problems, including all workshop power supply problems, such as low power supply, safe combustion, poor power plug contact, etc. The air pump or hydraulic pump is not open, the air blow three parts are not open, the discharge valve or some pressure valve in the hydraulic system is not open, etc., the detection of automatic screw tightening machine fault should include the following aspects:
1. Power supply
The most basic needs of the automatic screw tightening machine, including the power supply of each equipment and the power supply of the workshop. The air source includes the air source pressure required by the air blowing equipment. Hydraulic sources, including the working state of hydraulic pumps, are used in automation equipment and hydraulic equipment.
2. Whether the sensor direction is offset
Automatic screw tightening machine has more safety and detection sensors, due to the negligence of equipment maintenance personnel, it may be the positioning error of some sensors, such as not in place, sensor failure, sensitivity failure, etc. Often observe the induction direction and sensitivity of the sensor of the automatic screw tightening machine, find errors and adjust them in time. If the automatic screw tightening machine sensor is broken, replace it immediately.
3, relay, flow control valve, pressure control valve
The relay of the automatic screw tightening machine and the magnetic induction sensor are the same, and the long-term use of the iron core will also appear to be glued, and then the circuit cannot be guaranteed to be normal, and it needs to be replaced. In air blowing or hydraulic systems, with the movement of the equipment, the opening of the throttle valve and the pressure regulating spring of the pressure valve will also loosen or slide.
4, electrical, air blowing and hydraulic circuit connection
Automatic screw tightening machine fault detection The above three steps do not show any doubt, then look at all the cycles. Check whether the wire in the line is broken, especially whether the wire in the slot is pulled by the slot, check whether the gas pipe is damaged, and see if the hydraulic pipe is blocked. If the trachea is severely creased, it should be replaced immediately
