Maintenance of radial drilling machine

Feb. 22, 2020


The application of PLC in the electrical control of radial drilling machine, the traditional relay contactor electrical control system of radial drilling machine is technically reformed by PLC, and the design ladder diagram, input and output wiring diagram of PLC electrical control system of radial drilling machine are given. The application of PLC not only greatly improves the reliability and anti-interference ability of the electrical control system of radial drilling machine, but also greatly simplifies and reduces the workload of maintenance.


In the future, the outer diameter of the radial drilling machine will increase. The radial drilling machine is not clamped. The drill bit is not well ground. If the center is deviated, there will be small errors. The price of the radial drilling machine is not good. How to deal with the change of the spindle speed? The hydraulic pressure is lack, or the hydraulic oil is small. You can add some hydraulic oil. You can take measures to start the machine to repair the change of speed cylinder. If possible, it is the pin in the cylinder head and the shift fork If there is no action, it may be that the oil cylinder is stuck, or the pressure in the oil circuit is not available, or the valve of the hydraulic system is faulty, what should be done if the radial drilling machine is not easy to change speed? It is suggested to check whether the forward and reverse forks one by one are qualified, whether the pressure of the oil pump can reach the demand, and whether there is a pressure measuring bolt on the upper end of the speed change valve to loosen and use a pressure gauge to measure the pressure, assuming that the pressure is not, and the adjusting nut on the oil pump has no margin to put some gasket into it.


If the above situation is not effective, it is the reason for the sky color. The sky color temperature is reduced, which causes the hydraulic oil to become viscous. It is recommended to replace the hydraulic oil. If it is still not effective, it is necessary to introduce the replacement oil of the friction plate in order to check whether the friction plate can be worn. If it is still not possible, it is the sealing function of the positive and reverse fork oil cylinder Bad buffer doesn't work! As a result, the oil volume in the forward rotating oil chamber of the oil cylinder is insufficient, and the slow operation of the gears is ineffective.


The first level protection of radial drilling machine operates for 600 hours to carry out the first level protection, which is mainly carried out by the operators and cooperated by the maintenance workers. The first step is to cut off the power supply, and then carry out the protection work platform to polish the burr, clean the screw rod, rack, gear, etc.; clean the oil line, felt, fill the smooth oil system without any shortage, dredge the oil path, and light the oil level; check the oil quality and oil quantity, and increase the oil level as appropriate Add smooth oil to clean the water pump, filter and coolant tank; the system shall be intact, the pipeline shall be unblocked, and the motor and electrical box shall be wiped without leakage; check the limit switch and grounding wire.


The radial drilling machine produced by Zaozhuang Make Machinery Co., Ltd. is of high quality and well received by customers.
