Description
Technical Field
The invention belongs to the field of machine tool machining, and particularly relates to an intelligent cooling and lubricating device and method applied to a numerical control machine tool.
Background
The numerical control machine tool is a high-efficiency automatic machining device which consists of a mechanical device and a numerical control system and is used for machining complex parts, and the numerical control machine tool is an important component of the manufacturing industry in China. In machining, it is often necessary to cool and lubricate the machining area in order to improve tool life and improve machining quality. At present, cooling and lubricating are mainly carried out through cutting fluid in actual production of a factory, but a large amount of lubricating cutting fluid is used, so that not only can the lubricating effect of the cutting fluid not be fully exerted and the production cost be improved, but also the soil geological environment is seriously polluted, and the volatile oil mist of the cutting fluid also can form a great threat to the health of workers; and the compressed air or the cooling compressed air is independently used for auxiliary processing, so that the cooling and lubricating effects are not obvious although the environment is protected and saved. In addition, in actual processing, a quantitative monitoring means for a cooling and lubricating medium is lacked, fuzzy control is often performed or only on/off binary control is performed depending on the experience of workers, so that the processing precision of manufactured parts is greatly influenced, and particularly, the surface metallographic structure change condition, the surface hardness, the residual stress and other surface layer mechanical properties which are closely related to the cooling and lubricating medium are influenced. Therefore, the industry needs to develop a novel cooling and lubricating device which is efficient, environment-friendly and capable of being quantitatively monitored.
The vortex effect means that when the airflow rotates at a high speed in the vortex tube, the airflow is converted and separated into two parts of airflows with different temperatures through vortex, the temperature of the airflow at the central part is lower than that of the airflow at the outer layer, the two parts of airflows can be separated to obtain low-temperature airflow without using additional refrigeration equipment, and the existing vortex tube refrigeration method is applied to a plurality of technical fields in the world. The micro-lubricating technology (MQL) is characterized in that a compressed gas and a small amount of lubricating oil are mixed and vaporized to form micron-sized liquid droplet oil mist, and the micron-sized liquid droplet oil mist is sprayed to a cutting area of a machine tool at a high speed through a nozzle to carry out effective cooling and lubrication. By organically combining the vortex refrigeration effect with the micro-lubrication technology, the low-temperature compressed air subjected to vortex refrigeration is mixed with the atomized cutting fluid and then is sprayed to a cutting area, so that the efficient and economical cooling and lubricating effect can be achieved, and the novel cooling and lubricating device is a novel product capable of replacing the existing cooling and lubricating equipment on a large scale.
Chinese patent publication No. CN107524906B discloses a minimal quantity lubrication device, which utilizes a modularized liquid flow regulator to connect a liquid conduit and a gas conduit, and can eject continuous or discontinuous air or lubricating liquid jet flow as required, and the minimal quantity lubrication device can fully mix compressed air and lubricating liquid, but cannot further cool a cutting area through low temperature; chinese patent publication No. CN109731705A discloses a minimal quantity lubrication device and a use method thereof, wherein an oil outlet of the device is connected with a fluid control valve, the fluid control valve is connected with a gas flow valve, and mixed liquid is atomized and then sprayed out through a nozzle; chinese patent publication No. CN108106038A discloses a counter-flow vortex tube type miniature refrigerator, which utilizes the vortex refrigeration effect to realize gas refrigeration through a counter-flow vortex tube, but the airflow injected from the refrigeration end has only the refrigeration effect, and the function is single, and the lubrication condition of the cutting area is not improved. In summary, the cooling and lubricating devices in the field of machining of numerical control machine tools at present have certain limitations, and lack of intelligent monitoring devices designed in a matching manner, so that real-time quantitative monitoring of cooling and lubricating media in machining is difficult to realize individually, and an intelligent cooling and lubricating device which is efficient in cooling and lubricating, low in cost, portable, easy to install, energy-saving and environment-friendly is urgently needed.

10. Use method of intelligent cooling and lubricating device for numerically controlled machine tool according to any of claims 1 to 9, characterized by comprising the following four main steps:
step one, gas-liquid input: compressed air of a compressor and lubricating cutting fluid of a fluid pump respectively flow into an air inlet pipe and a fluid inlet pipe of a cooling and lubricating system by opening an air inlet switch and a fluid inlet switch;
step two, cooling and flow control: the compressed air of the air inlet pipe flows into the vortex cooling chamber, low-temperature compressed air is generated under the vortex refrigeration effect and is output through the cold end pipe, the temperature range of the low-temperature air is-30 to-10 ℃, and the temperature is controlled by a temperature regulator arranged at the tail end of the hot end pipe; the lubricating cutting fluid flowing out of the liquid inlet pipe is output through the liquid flow control pipe after being regulated and controlled by the flow regulator;
step three, gas-liquid mixing: the flow-controlled lubricating cutting fluid of the liquid flow-control pipe and the low-temperature compressed air of the cold end pipe are fully mixed in the gas-liquid mixing chamber to form low-temperature lubricating aerosol, and the low-temperature lubricating aerosol is output to an externally-connected spray head through a mixed medium output pipe so as to cool and lubricate a cutting area; particularly, if the air inlet switch is opened and the liquid inlet switch is closed, the cooling and lubricating system only inputs compressed air and outputs the cooled and compressed air after vortex cooling, and the function of the cooling and lubricating system is equivalent to that of a vortex cooling pipe;
step four, intelligent monitoring: the temperature of low-temperature compressed air and the flow of lubricating cutting fluid are monitored in real time by utilizing various sensors arranged in a cooling and lubricating system, acquired data are displayed on a state display screen in real time after analog-to-digital conversion and coding and decoding, and the starting and the closing of the state monitoring system are automatically controlled by a circuit control switch.
