Abstract

The invention discloses a nano-liquid electrostatic atomization and thermoelectric heat pipe integrated trace lubrication grinding device which comprises a grinding wheel with heat pipes and an electrostatic atomization combined spray nozzle in thermoelectric refrigeration and magnetic enhancement electric fields. Thermoelectric film materials cover the surfaces of two sides of the grinding wheel with the heat pipes, and extra electric fields are applied to the outsides of the thermoelectric film materials; a high-voltage direct-current electrostatic generator and a magnetic field forming device are arranged on the outside of the electrostatic atomization combined spray nozzle; the electrostatic atomization combined spray nozzle is connected with a nano-particle liquid supply system and a gas supply system; nano-liquid is subjected to electrostatic atomization and is sprayed to grinding zones by the electrostatic atomization combined spray nozzle, and heat in the grinding zones can be absorbed; the heat can be absorbed by the thermoelectric film materials in the grinding zones under thermoelectric effects, and absorbed heat can be dissipated by the grinding wheel with the heat pipes after the thermoelectric film materials are separated from the grinding zones, so that a Carnot cycle can be formed. The nano-liquid electrostatic atomization and thermoelectric heat pipe integrated trace lubrication grinding device has the advantages that nano-liquid electrostatic atomization and thermoelectric refrigeration and heat pipe refrigeration technologies are integrated with one another, accordingly, a large quantity of grinding heat can be absorbed after the nano-liquid electrostatic atomization and thermoelectric heat pipe integrated trace lubrication grinding device reaches the grinding zones, the grinding temperatures can be reduced, and obvious refrigeration effects can be realized for the grinding zones.

Description

technical field [0001] The invention relates to a grinding process and device, in particular to a micro-lubrication grinding device integrating electrostatic atomization of nano fluid and electric card heat pipe. Background technique [0002] Grinding is an important processing technology for finishing. The processing process is to use the grinding wheel to interact with the workpiece. Since the abrasive grains on the surface of the grinding wheel are usually cut with a negative rake angle, the heat generated during the grinding process is much greater than other processing forms. Abrasive grains consume a lot of mechanical energy when grinding the workpiece material and convert it into heat. A very small part of the heat at the grinding interface is taken away by the grinding debris, and more than 90% of the heat is transferred to the grinding wheel and the workpiece substrate, which has a great impact on the service life of the grinding wheel and the workpiece.
