Embodiment Construction

[0013] The technical solutions in the embodiments of the present invention will be described clearly and completely below. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0014] The invention provides an active heat dissipation grinding wheel (see Figure 1-3 , Referred to as grinding wheel), including grinding wheel disc body 1, aluminum core 2 and diaphragm 3;

[0015] The grinding wheel disc body 1 has a central cavity 11, a central through hole 12, a heat dissipation groove 13 and a heat dissipation through hole 14. The heat dissipation groove 13 is located on the lower surface of the grinding wheel disc body 1, and is formed by a central diverging groove 131 and an annular shape. The groove 1...

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] When grinding or cutting materials, the grinding wheels commonly used in engineering often generate a lot of grinding heat due to friction, which is easy to cause burns and cracks on the surface of the workpiece, which seriously affects the surface processing quality of the workpiece. [0003] In the prior art, methods of increasing the heat dissipation area or changing the configuration of the grinding wheel for heat transfer are mostly adopted, and the passive heat dissipation method is used to achieve the purpose of heat dissipation. Application No. 201020166002.5 discloses a grinding wheel that is easy to dissipate heat. The technical solution adopted is to connect an aluminum core through the center of the grinding wheel disc body and design annular grooves on the upper and lower surfaces of the disc body to di...
