Introduction
As an important part of modern industry, CNC machine tools are widely used in various manufacturing fields. The service life and overall performance of CNC machine tools depend largely on their lubrication condition. Poor lubrication of CNC machine tools will cause excessive friction between parts, resulting in increased wear and premature failure.
In the traditional machine tool lubrication system control method, an operator manually performs a certain amount of oil charge according to the lubrication requirements of the machine tool. In order to reduce the influence of oil leakage and late lubrication, the development of machine tool lubrication system control has become the premise of machine tool performance and service life.
Oil Pressure Detection and Alarm System
The oil pressure detection and alarm system is a system mainly responsible for checking the oil pressure at the lubrication point of the machine tool. The system is mainly composed of a digital pressure gauge and multiple pressure switches. The digital pressure gauge can show the readings of the pressure switches in real time, and the pressure switches can automatically detect the change of pressure inside the machine tool. When the pressure exceeds the safe value, the system immediately generates an alarm.
The oil pressure detection and alarm system has the following advantages: (1) The main pressure parameters of the machine tool can be more accurately monitored, including: oil pressure, oil temperature, vibration, etc. (2) The system can automatically alarm when the pressure exceeds the safe value, thus avoiding the failure of the machine tool caused by the overload of pressure.
Oil Quantity Control System
Oil quantity control system mainly includes two parts: oil quantity measuring device and oil flow control device. The oil quantity measuring device is mainly to measure the oil quantity in the pipeline of the machine tool. The control system can compare the measurement results with the set parameters and accurately adjust the oil quantity in the pipelineT hat can meet the lubrication requirements of different components in the machine tool.
The oil flow control device can automatically adjust the flow rate of the oil, thus ensuring the uniformity and stability of the oil, and avoiding the problem of oil leakage and insufficient oil.
Oil Quality Testing System
The oil quality testing system is mainly used to detect the quality of the oil in the machine tool and find out the embedded small particles in the oil. The system mainly includes an oil quality tester and an oil filter.
The oil quality detector works by sending an ultrasonic wave through the oil, and then reflecting the ultrasonic wave by detecting the small particles embedded in the oil. Then display the oil quality parameters. The oil filter can filter out all the impurities detected by the oil quality detector in order make clean and high quality oil, and realize the protection of machine tool lubrication system.
Advantages of New System
The newly developed system is composed of an oil pressure detection and alarm system, an oil quantity control system and an oil quality testing system. Compared with the traditional machine tool lubrication system control method, the newly developed system has the following advantages:
1.The newly developed system can accurately measure the main pressure parameters of the machine tool, such as oil pressure, oil temperature, vibration, etc.. This can help to adjust the oil pressure in the machine tool in real time, and also prevent the machine tool from being overloaded due to excessive pressure.
2. The oil flow control device in the system can automatically adjust the flow rate of the oil, thus ensuring the uniformity and stability of the oil and avoiding the problem of oil leakage and insufficient oil.
3. The oil quality testing system can quickly detect the impurities in the oil, and the oil filter can filter out all the impurities in the oil. This makes clean and high quality oil and protect the lubrication system of machine tool.
Conclusion
In conclusion, through the development of the new system, the oil leakage of the machine tool and the improper use of the oil can be avoided, and the lubrication state of the machine tool can be improved, so that the working efficiency of the machine can be improved and the service life of the machine tool can be extended.
