The data acquisition and control system 8 may be a single chip or a computer. According to the control requirement of the embodiment, a 1T-8501 singlechip with the model of STC15W4K32S4 is selected, and when the working frequency is the same, the working speed is 8-12 times that of the common 805 series, and the working voltage is about 2.5-5.5V.
The oil supply mode of the oil-gas lubrication is periodic oil supply, so according to the oil supply quantity of a system and the requirements of the oil supply mode, the oil pump 9 adopts a Nanjing Hencui full-automatic gear pump, the pump has two operation modes, namely manual operation and electric control, manual operation is used for initial lubrication, after the initial lubrication is finished, a pressure switch is controlled by a single chip microcomputer under the electric control mode, the oil supply time and the oil supply period of the oil pump are set according to the requirements, and the oil supply time interval and the oil supply period are selected to determine the oil supply quantity. The working principle of the gear pump is as follows: when the system is pressurized, oil is injected, the indicating rod extends out, the oil is stored after the system is unloaded, and the viscosity of the lubricating oil cannot influence the flow. The oil mass distributor adopted by the application is an RH-3203 progressive distributor, and accurate oil supply of each friction pair can be realized.
Because the transportation of the lubricating oil needs compressed air to provide power, the pressure value of the air compressor is generally 0.2-0.5 Mpa. In an oil-gas lubrication system, compressed air has both a conveying function and a cooling function, and the consumption of the compressed air is influenced by multiple factors, so that 550W-8L of Ottos in Taizhou is selected as an air source to meet the production requirement.
Research shows that the compressed air is dirty or the water content is too high, so that the system of oil-gas lubrication is in failure, the stability of an oil film is also damaged, and the precision of an air filtering and pressure reducing valve is required to be not less than 5 mu m. In order to meet the requirement, the T50 air filtering pressure reducing valve is selected to filter the compressed air, and the filtering precision is 5 μm; in this embodiment, need regulate and control this important oil gas parameter of air feed speed, consequently selected for use the gas flowmeter to control the gas flow who measures after filtering, combine the condition demand, select for use the model to be: the MF300-RS232-AIR-500-4mm fast screwing gas flowmeter has the maximum gas flow of 5L/min, and the specific gas flow output can be regulated and controlled through a single chip microcomputer.
The oil-gas mixing block is a key component of an oil-gas lubricating system, and the performance and reliability of the oil-gas mixing block are closely related to the lubricating effect. The main function of the oil-gas lubricating device is to mix lubricating oil delivered by the oil distributor with filtered compressed air, deliver the mixed lubricating oil to a friction pair through an oil-gas pipeline, and spray the mixed lubricating oil out through a nozzle to complete the whole oil-gas lubricating process. The selected oil-gas mixing block is also of Nanjing Hencui lubrication equipment company, the flow rate of the oil-gas mixing block is 0.1ml/cyc, the working period of the oil-gas mixing block depends on the oil supply period of an oil pump, and the oil-gas mixing block is adjusted according to the required oil supply amount.
The working principle of the oil-gas mixing block is as follows: after the oil pump starts to work, the main pipe sends lubricating oil to form a certain pressure, the lubricating oil in the quantitative plunger cavity is pressed out, and after the main pipe releases the pressure, the quantitative plunger cavity is filled with the lubricating oil again. The diameter of the nozzle affects the divergence angle of the lubricant outlet, and in this embodiment, a nozzle with a bore diameter of 1.2mm is used.
The implementation of the control parameters is set forth in detail below.
Oil pressure and air pressure regulation
According to the set value, the oil pressure and air pressure values are collected and read in real time through an oil pressure sensor and an air pressure sensor, in order to improve the precision, the oil pressure and air pressure values are measured for 10 times, then the average value is obtained, and finally the average value is stored in an oil pressure register and an air pressure register respectively.
Because the oil supply is periodic and the air supply is continuous, a constant pressure treatment of the oil pressure is required. The oil pressure deviation is read by an oil pressure sensor according to the set oil pressure, and the controller controls the start and stop of the oil pump to complete the output of the constant oil pressure, and the control flow chart is shown in fig. 2.
② air flow control
The gas output by the air compressor reaches the gas flowmeter after passing through the air filtering pressure regulating valve, the gas flowmeter is set with a gas flow value, and the numerical value is set at the beginning of the operation.
③ regulating and controlling oil temperature

When the test is started, a temperature value is set, an oil temperature sensor measures an oil temperature signal value, temperature deviation is read, a single chip microcomputer sends out an instruction, a heating pipe is started to start heating, when the set value is reached, the oil temperature sensor measures the oil temperature deviation again, when the deviation reaches the accuracy range of the oil temperature sensor, the heating of equipment is stopped, and a control flow chart is shown in a figure 3.
Liquid level alarm
In order to protect the normal work of the oil pump, the oil pump oil lower limit alarm is set so as to feed back and process in time.
The numerically controlled grinder also comprises a display for displaying data in real time, and the display is electrically connected with the data acquisition and control system 8. The display can display the data of oil pressure, oil temperature, air pressure, air flow, oil injection period, oil injection time, set oil pressure, set oil temperature, set air flow and the like.
