Problems solved by technology

Although this solution realizes the controllable orientation of the nanoparticle jet, in this case, if you want to further increase the charge amount of the droplet, you need to continuously increase the voltage of the DC power supply, but due to the limitation of the breakdown voltage, you cannot How to increase the electrostatic voltage without increasing the electrostatic voltage has become the main research direction. On the basis of increasing the charge amount of the droplet was explored

Abstract

The invention relates to a conveying capacity controllable nano particle jet flow minimal quantity lubrication grinding device in an enhanced magnetoelectricity field. Through adding of a magnetic field on the periphery of a corona zone, the charge capacity of liquid drops is increased. The device comprises a spray nozzle, a nano particle liquid feeding system, a gas supply system, a high-voltage DC electrostatic generator, an adjustable high voltage DC power supply and a magnetic field forming device. The high-voltage DC electrostatic generator and the magnetic field forming device are arranged outside the spray nozzle. The spray nozzle is connected with the nano particle liquid feeding system and the gas supply system. The high-voltage DC electrostatic generator is connected with the negative pole of the adjustable high voltage DC power supply. The positive pole of the adjustable high voltage DC power supply is connected with a workpiece power-up device which is used for being attached to a non-machined surface of a workpiece, and consequently a negative corona discharge form is formed. The magnetic field forming device is arranged on the periphery of the corona zone with electrostatic discharge. Nanofluid grinding fluid is sprayed out of a spray head of the spray nozzle and is atomized to be the liquid drops, and at the same time, the liquid drops are charged under the action of the high-voltage DC electrostatic generator and the magnetic field forming device and then are fed into a grinding region.

Description

technical field [0001] The invention relates to a process method and equipment for transporting micro-lubricating grinding fluid for mechanical grinding, in particular to a nano-particle jet flow controllable transporting micro-lubricating grinding equipment under a magnetically enhanced electric field. 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 pol...
