The electric spindle oil-air lubricating device comprises an electric spindle assembly with a rotation speed measuring element, an air adjusting mechanism, an oil amount control mechanism and a mixing mechanism; a front bearing anda back bearing are each provided with a temperature measuring element; the electric spindle assembly is provided with a first oil way communicating with the front bearing and a second oil way communicating with the back bearing; the electric spindle assembly, the oil amount control mechanism and the mixing mechanism sequentially communicate with one another to form a circulating loop, and the mixing mechanism communicates with the first oil way and the second oil way; the mixing mechanism is provided with an oil-air mixing valve; the air adjusting mechanism communicates with the mixing mechanism, and the oil amount control mechanism is electrically connected with the air adjusting mechanism; and the oil amount control mechanism is used for controlling the opening degree of the air adjusting mechanism and the flow of lubricating oil introduced into the mixing mechanism according to the measured temperature and rotation speed.
Description
Technical field [0001] The invention relates to the technical field of bearing lubrication, in particular to an electric spindle oil-air lubrication device, a control system and a control method. Background technique [0002] CNC machine tools are developing in the direction of ultra-high-speed and ultra-precision. The spindle of the machine tool is the most critical part of the CNC machine tool. The motorized spindle of the machine tool integrates the spindle and the motor in structure, and has the advantages of low noise and wide speed adjustment range. [0003] The current electric spindle has the following technical problems: the spindle accuracy error caused by the increase in lubricating oil temperature is too large. In the prior art, when the problem is improved, the increase in the amount of oil at the front and rear bearings will improve the temperature rise, but the amount of oil used for lubrication is often not automatically adjusted, and the spindle speed in which it ...
