Description

Technical Field

[0001] The utility model relates to the technical field of diamond grinding wheels, in particular to a diamond grinding wheel. Background Art

[0002] The circular bonded abrasive with a through hole in the center made of diamond abrasive as raw material and metal powder, resin powder, ceramic and electroplated metal as binders is called diamond grinding wheel (alloy grinding wheel). The structure of diamond grinding wheel is different from that of ordinary abrasive grinding wheel. Generally, it is composed of diamond abrasive layer, transition layer and matrix. The working layer is also called diamond layer, which is composed of abrasive, binder and filler, and is the working part of the grinding wheel. The transition layer is also called non-diamond layer, which is composed of binder, metal powder and filler. It is the part that firmly connects the diamond layer to the matrix. The matrix is ​​used to receive the abrasive layer and is firmly clamped on the spindle of the grinder with a flange when in use. Generally, metal binder products use steel and alloy steel powder as the matrix; resin binder products use aluminum alloy and bakelite as the matrix. It is made of aluminum, steel or bakelite, and plays the role of supporting the working layer and clamping the abrasive. The quality of grinding wheel molding and the accuracy of use are closely related to the matrix.

[0003] When the existing diamond grinding wheel is in use, friction between the existing diamond grinding wheel and the object being ground often generates a high temperature. The high temperature can easily seriously reduce the life of the diamond grinding wheel, affecting the life of the diamond grinding wheel. In addition, the existing diamond grinding wheel is often installed on the output shaft of the grinding machine when in use. However, the sizes of the output shafts of different models of grinding machines are different. When the mounting hole of the diamond grinding wheel is larger, it is often unable to adapt to the output shaft of the grinding machine with a smaller diameter, and the installation adaptability is poor. Therefore, the existing diamond grinding wheel has the disadvantages of being inconvenient to dissipate heat for the grinding wheel and having poor installation adaptability. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Example 1

[0023] The utility model provides a technical solution: a diamond grinding wheel, comprising a diamond grinding wheel body 1, a heat sink 2 is fixedly connected to the left side of the diamond grinding wheel body 1, a heat exchange fin 3 is fixedly connected to the outer surface of the heat sink 2, a plurality of heat exchange fins 3 are arranged and are evenly distributed in a circular array, a centrifugal blade 4 is fixedly connected to the outer surface of the heat sink 2, the centrifugal blade 4 is inclined, a plurality of centrifugal blades 4 are arranged and are evenly distributed in a circular array, an air inlet pipe 5 is fixedly connected to the end of the centrifugal blade 4, an air guide cover 6 is fixedly connected to the outer surface of the air inlet pipe 5, an air guide block 7 is fixedly connected to the outer surface of the heat sink 2 located on the inner side of the centrifugal blade 4, a fixed shaft 8 is fixedly connected to the outer surface of the air guide block 7, a fan blade 9 is fixedly connected to the outer surface of the fixed shaft 8, four fan blades 9 are arranged and are evenly distributed in a circular array, and a protective filter 10 is fixedly connected to one end of the air inlet pipe 5.

[0024] In order to facilitate the heat dissipation of the grinding wheel, Figures 1 to 6As shown, the present application adopts the following structure. Through the arrangement of the heat sink 2, the heat exchange plate 3, the centrifugal blades 4, the air guide cover 6 and the fan blades 9, the diamond grinding wheel has the effect of facilitating the heat dissipation of the grinding wheel. Through the coordinated arrangement of multiple centrifugal blades 4 and the heat exchange plate 3, during use, when the grinding wheel rotates, through the arrangement of several centrifugal blades 4, when the diamond grinding wheel body 1 rotates, the heat sink 2, the heat exchange plate 3 and the centrifugal blades 4 rotate together. When the centrifugal blades 4 rotate, high pressure is formed inside, and through the arrangement of the air guide block 7, the outside air enters from the end of the air inlet pipe 5 and is blown out from the right side of the air guide cover 6 and the left side of the heat sink 2. When blowing, the heat of the heat sink 2 and the heat exchange plate 3 can be exchanged with the air to dissipate the heat of the grinding wheel. In addition, through the arrangement of the air guide cover 6, the air can be better circulated along the outer surface of the diamond grinding wheel body 1, and the diamond grinding wheel can be directly cooled. The diamond grinding wheel body 1 is used for heat dissipation, and the wind blown out from between the air guide cover 6 and the diamond grinding wheel body 1 can directly dissipate heat to the workpiece body and the grinding position in contact with the diamond grinding wheel body 1 during grinding, thereby effectively improving the heat dissipation effect. Through the coordinated arrangement of the air inlet pipe 5, the air guide cover 6, the air guide block 7, the fixed shaft 8 and the fan blades 9, when in use, when the grinding wheel rotates, the fan blades 9 also rotate with the grinding wheel, thereby driving the air to blow from the end of the air inlet pipe 5 to the inner side of the plurality of centrifugal blades 4. Through the centrifugal force generated when the centrifugal blades 4 rotate, the air is blown out to the outside, thereby accelerating the air circulation speed and further improving the heat dissipation effect. Through the arrangement of the protective filter 10, debris can be prevented from entering from the end of the air inlet pipe 5, effectively preventing the blockage between adjacent centrifugal blades 4 and adjacent heat exchange plates 3, and also improving the safety performance, thereby achieving the purpose of facilitating the heat dissipation of the grinding wheel.
