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

Embodiment 1

[0079] The first embodiment of the present invention figure 1 with Figure 3 to 17 Shown, it is about a magnetically enhanced electric field induced nanoparticle jet droplet charging mechanism and droplet controllable and orderly transport micro-lubrication grinding process and equipment.

[0080] Such as figure 1 As shown, in the first embodiment, part of the worktable 2 of the grinder is covered with an insulating plate 3 (this new type of material can be magnetic but not conductive, so as to ensure the installation of the workpiece 4 and the nozzle 12 and the workpiece 4 to form a stable electric field). Place the workpiece 4 on the insulating plate 3, clamp and position the workpiece 4 when the grinder is magnetized, and attach the magnetic chuck 5 to the side of the grinding wheel cover 6 to fix the nanofluid conveying serpentine tube 8, compressed air conveying serpentine tube 7 And the negative electrode wire in the high-voltage wire 10 of the electrode. One end of the na...

[0087] figure 2 To 5 and Figure 18 to 22 This is the second embodiment of the present invention. In the second implementation, the nozzle 12 and the electromagnetic device 13 in the first embodiment are replaced with an integrated nozzle 110.

[0088] Such as figure 2 As shown, part of the worktable 2 of the grinder is covered with an insulating plate 3 (this new type of material can be magnetically conductive, but not conductive, which can ensure the installation of the workpiece and the formation of a stable electric field between the nozzle and the workpiece). Place the workpiece 4 on the insulating plate 3, clamp and position the workpiece 4 when the grinder is magnetized, and attach the magnetic chuck 5 to the side of the grinding wheel cover 6 to fix the nanofluid conveying serpentine tube 8, compressed air conveying serpentine tube 7 And the negative electrode wire in the high-voltage wire 10 of the electrode. One end of the nanofluid conveying serpentine tube 8 is conn...

Embodiment 3

[0094] The third embodiment of the present invention figure 1 , image 3 To 5, Image 6 , Figure 7 , Figure 9 to 16 with Figure 23 As shown, in the third embodiment of the present invention, except that the arrangement of the electrodes and the design of the spray head are different from the first embodiment, other designs are the same as the first embodiment. In the third embodiment, the method of adding the discharge electrode is changed. The L-shaped needle electrode I83 is no longer arranged in the electrode slot 68 on the electrode chuck 51 in the original first embodiment. In the third embodiment, the electrode The chuck 51 is only used as a cover of the magnetic box 52. In the third embodiment, the spray head 18 in the first embodiment is redesigned. The design scheme is as follows: Figure 23 As shown, the spray head 18 in the original first embodiment is split into two parts: the spray head body 111 and the electrode nozzle I 112. The spray head body 111 and the ele...

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 mechanical grinding processing micro-lubricating grinding fluid transportation process and equipment, in particular to a nano-particle jet controllable transportation of micro-lubricating grinding equipment under a magnetic enhanced electric field. Background technique [0002] Minimal quantity lubrication technology is also called MQL (Minimal Quantity Lubrication) technology. It mixes and atomizes a very small amount of lubricating fluid with compressed air with a certain pressure, sprays it to the grinding area, and touches the grinding wheel and the grinding debris, the grinding wheel and the workpiece The surface is effectively lubricated. 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 of the traditional casting lubrication method) to reduce costs and environmental pollution and harm to the human body . ...
