Abstract

The invention discloses a nanofluid electrostatic atomization controllable conveying micro quantity lubricating system for auxiliary electrode focusing. The problem that the micro quantity lubricatingliquid deposition rate is low in the prior art is solved. The system has the beneficial effects of improving the atomization cone form, deposition area and shape of fogdrop groups. According to the scheme, a nozzle for nanofluid micro quantity lubricating liquid comprises a gas-fluid mixing component, a corona discharge component and an auxiliary electrode focusing component. The nozzle is connected with a fluid supply system and a gas supply system. The corona discharge component is connected with the negative pole of an adjustable high voltage direct current power source, the positive poleis connected with a workpiece charging component and grounded, and a needle-plate negative corona discharge electric field. The auxiliary electrode focusing component is located below a corona area and connected with the negative pole of a power converter, the positive pole is grounded, and an additional electric field is formed. Under the effect of a nozzle gas-fluid mixing cavity, micro quantitylubricating fluid is atomized to spray out fogdrop groups, charged in the discharge electric field, atomized for the second time, focused towards the center axis under the effect of the auxiliary electrode focusing component, and controllably conveyed to a grinding area.

Description

technical field [0001] The invention relates to the technical field of grinding processing, in particular to a nanofluid electrostatic atomization controllable transportation micro-quantity lubrication system with auxiliary electrode focusing. Background technique [0002] Minimal quantity lubrication technology is a typical environment-friendly and green cutting technology. A small amount of lubricating fluid is mixed and atomized with compressed air with a certain pressure, sprayed into the grinding area, and the contact surface between the grinding wheel and the grinding debris, and the grinding wheel and the workpiece is cooled. lubricating. Under the premise of ensuring effective lubrication and cooling effect, this technology uses the minimum amount of grinding fluid (about a few thousandths of the amount used in traditional pouring lubrication methods), which can reduce costs, environmental pollution and human damage. . The particle size distribution of the mist and...
