Abstract

The invention discloses an active cooling grinding wheel which comprises a grinding wheel disc body, an aluminum core and a diaphragm. The grinding wheel disc body is provided with a center cavity, a center through hole, cooing grooves and cooling through holes. Under the condition of not affecting the grinding efficiency and the intensity of the grinding wheel, the cooling grooves and the cooling through holes are additionally formed, a closed and crossed cooling belt is built, the cooling area is ensured, and internal heat of the grinding wheel disc body is dissipated in time; the diaphragm structure of the grinding wheel effectively utilizes vibration generated in the grinding process and is combined with the cooling grooves and the cooling through holes, and the active cooling mode is formed. The diaphragm vibrates to drive air in two cavities of the grinding wheel disc body to vibrate, air flow enters the cooling through holes and the cooling grooves, and the purpose of heat loss through convection is achieved.

Description

technical field [0001] The invention relates to the field of processing tools, in particular to an active heat dissipation grinding wheel. Background technique [0002] Grinding wheels commonly used in engineering often generate a lot of grinding heat due to friction when grinding or cutting materials, which can easily cause burns and cracks on the surface of the workpiece, seriously affecting the surface processing quality of the workpiece. [0003] In the prior art, most of them adopt the method of increasing the heat dissipation area or changing the configuration of the grinding wheel for heat transfer, and the passive heat dissipation method is used to achieve the purpose of heat dissipation. The application number is 201020166002.5, which discloses a grinding wheel that is easy to dissipate heat. The adopted technical solution is to connect the aluminum core through the hole in the center of the grinding wheel disc body and design annular grooves on the upper and lower ...
