Minimum quantity lubrication supply system capable of automatically regulating oil mist quantity for machine tool processing

Abstract

The invention relates to a minimum quantity lubrication supply system capable of automatically regulating the oil mist quantity for machine tool processing. The minimum quantity lubrication supply system comprises a gas conveying switch, at least one electromagnetic switch, a one-way valve, a flow rate control valve and an atomizing chamber, wherein the atomizing chamber contains cutting oil, the inner side wall of the top of the atomizing chamber is provided with at least two Venturi atomizing spray heads, the gas conveying switch is sequentially connected with one Venturi atomizing spray head through a gas conveying pipe, the gas conveying switch and the at least one electromagnetic valve are respectively and sequentially connected with the at least one Venturi atomizing spray head through a gas conveying pipe, the one-way valve and the flow rate control valve are sequentially connected through an oil liquid conveying pipeline, the bottom of the oil liquid conveying pipeline is communicated with the bottom of the atomizing chamber, the top of the flow rate control valve is connected with the at least two Venturi atomizing spray heads through an oil liquid conveying pipeline, and a baffle plate is fixedly arranged in the atomizing chamber. The minimum quantity lubrication supply system has the advantages that the structure is simple, the oil mist spraying quantity at the outlet part can be automatically regulated, and in addition, the oil mist can be simultaneously used for a plurality of machine tools.

Description

technical field [0001] The invention relates to a micro-lubrication supply system that can automatically adjust the amount of oil mist for machine tool processing. The system can ensure that the oil mist overcomes the influence of centrifugal force and smoothly passes through the high-speed rotating spindle and the inner hole of the tool to reach the processing area. At the same time, the system will According to the diameter of the inner hole of the internal cooling tool, the spraying amount of the outlet oil mist is automatically adjusted; in addition, the system can also be used for the lubrication and cooling of the external cooling tool, and the system will automatically adjust the spray volume of each nozzle according to the number of nozzles. The oil mist injection amount belongs to the high-speed and high-efficiency green cutting technology field in mechanical processing. Background technique [0002] High-speed cutting is a high-performance process technology that ...
