Nano-fluid electrostatic atomization controllable jet micro-lubrication grinding system

Abstract

The invention relates to a nano fluid electrostatic atomizing controllable jet stream minimal lubricating and grinding system. Sprayed fog drops can be controllably distributed through the electrostatic principle, so that the pollution to environment is reduced, and better health security is provided to workers. A grinding system is provided with a corona charging nozzle, wherein a nozzle body of the corona charging nozzle is connected with a liquid supply system and an air supply system; a high-voltage direct-current electrostatic generator on the lower part of the nozzle body is connected with the cathode of an adjustable high-voltage direct-current power supply; the anode of the adjustable high-voltage direct-current power supply is connected with a workpiece charging device; and the workpiece charging device is attached to the non-machined surface of a workpiece. Nano fluid grinding liquid is fed into the corona charging nozzle through the liquid supply system, meanwhile the air supply system feeds compressed air into the corona charging nozzle, the nano fluid grinding liquid is charged into controllable jet stream by the high-voltage direct-current electrostatic generator while being driven by the compressed air to be sprayed out and atomized from the nozzle body, and the controllable jet stream is controllably distributed to a grinding area of the machined workpiece under the actions of electric field force and aerodynamic force.

Description

technical field

[0001] The invention relates to a grinding fluid supply device in mechanical processing, in particular to a micro-lubricating grinding system of nano-fluid electrostatic atomization controllable jet flow. Background technique

[0002] Minimal Quantity Lubrication technology is also called MQL (Minimal Quantity Lubrication) technology. It mixes a very small amount of lubricating fluid with compressed air with a certain pressure and atomizes it, sprays it into the grinding area, and controls the contact between the grinding wheel and the grinding debris, and the grinding wheel and the workpiece. effectively lubricate the surface. Under the premise of ensuring effective lubrication and cooling effects, this technology uses the minimum amount of grinding fluid (about a few thousandths of the amount used in traditional pouring lubrication methods) to reduce costs, environmental pollution and harm to the human body .
