A kind of internal cooling grinding wheel

Abstract

A novel internal cooling grinding abrasive wheel comprises an abrasive wheel body and a grinding portion. The abrasive wheel body is provided with a downward opening. The upper end of the abrasive wheel body is connected with a machine tool cutter handle. The grinding portion is arranged at the bottom of the abrasive wheel body. The novel internal cooling grinding abrasive wheel further comprisesa cooling liquid guiding pipe. The cooling liquid guiding pipe is arranged in the inner cavity of the abrasive wheel body. The water inlet head end of the cooling liquid guiding pipe penetrates through the top of the inner cavity of the abrasive wheel body and communicates with a cooling liquid supplying portion. The water outlet tail end of the cooling liquid guiding pipe is fixedly arranged on the inner edge of the lower end of the abrasive wheel body. According to the novel internal cooling grinding abrasive wheel, through the arrangement of the independent cooling liquid guiding pipe, cooling liquid is guided in from the top of the abrasive wheel body and guided to the outer edge of the lower end of the abrasive wheel body, and when the grinding portion conducts grinding, the cooling liquid conducts cooling, lubricating and flushing on the grinding area at the same time; the cooling liquid guiding pipe is independently arranged in the inner cavity of the abrasive wheel body, the technical threshold is lowered, and the production technology is simple; and the internal cooling type abrasive wheel is easier to manufacture and low in production cost.

Description

technical field [0001] The invention relates to a grinding wheel, in particular to an internal cooling grinding wheel, which belongs to the field of grinding processing. Background technique [0002] In machining, grinding is one of the most widely used material removal methods and belongs to finishing. [0003] During the grinding process, due to severe plastic deformation and friction, a large amount of grinding heat is generated in the grinding area between the grinding wheel and the workpiece. If the heat cannot be dissipated in time, burns and cracks will occur on the surface of the workpiece, which will seriously affect the workpiece. Processing quality. Traditionally, cooling is done by pouring coolant on the outside of the grinding wheel with nozzles. However, during the operation of the grinding wheel, a certain thickness of airflow layer is formed around it, which will prevent the external coolant from entering the grinding area, so it is impossible to process the...

Problems solved by technology

[0005] The internal cooling grinding wheel used in previous studies usually processes various shapes of grinding fluid inner channels on the main body of the grinding wheel. However, in this scheme, the processing technology of the inner channels is complicated and the processing cost is high, which greatly increases the The overall production cost of the grinding wheel
