Abstract

The invention relates to a nanofluid micro-lubricating electrostatic atomization controllable jet internal cooling process system. Through the electrostatic atomization principle, the micro-lubricating cutting fluid droplets can be controlled to be distributed in the spray, and the uniformity of the droplet spectrum can be improved. , deposition efficiency and effective utilization of liquid, and can effectively control the movement of droplets, thereby reducing environmental pollution and providing better health protection for staff. The system includes an adjustable high-voltage DC power supply, an internal coolant tool changer, a high-voltage electrical conversion device and an integrated nozzle. The minimum quantity lubrication system supplies the inner cooling drill bit with the minimum quantity lubrication cutting fluid through the inner cooling tool changer. The adjustable high-voltage DC power supply transmits the positive electrode to the electrode needle of the integrated nozzle through the high-voltage electric conversion device, and the negative electrode is electrically grounded and transmitted to the workpiece through the electromagnetic joint, so that the electrode needle-workpiece area forms a corona charge electric field, which is beneficial to the micro-lubrication. The cutting fluid is charged by corona to realize electrostatic atomization.

Description

technical field [0001] The invention relates to an electrostatic atomization device for nano-particle micro-lubrication cutting fluid in mechanical processing, in particular to a system for nano-fluid micro-lubrication electrostatic atomization controllable jet internal cooling process. Background technique [0002] Minimal Quantity Lubrication technology, also known as MQL (MinimalQuantityLubrication) technology, is to mix a very small amount of lubricating fluid with compressed air with a certain pressure and atomize it, spray it into the grinding area, and carry out the contact surface between the grinding wheel and the grinding debris, and the grinding wheel and the workpiece. Effective lubrication. 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) to reduce costs, environmental pollution and human damage....

AI Technical Summary

Problems solved by technology

[0006] However, this system is only used in grinding processing conditions. The supply method of the minimum amount of lubrication cutting fluid is external injection, and the size of the electrostatic atomization nozzle is large and the precision is low. It cannot be used for internal cooling drilling, milling, boring machines, reamers, etc. Machine Tool

Therefore, the system cannot be generally adapted to machining, especially machining with internal cooling tools.
