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

[0002] With the development of science and technology, the requirements for workpiece processing accuracy are getting higher and higher. In grinding, in order to obtain higher processing accuracy, grinders or grinding wheels are sometimes used to process the workpiece. The grinding wheel is a tool used for grinding, polishing and trimming metals, wood and other materials. The grinding wheel can perform rough grinding, semi-finishing grinding, fine grinding, grooving and cutting on the outer circle, inner circle, plane and various surfaces of metal or non-metal workpieces.

[0003] The installation structure of the grinding wheel is to pass the shaft through the center of the grinding wheel and then fix it with a spiral structure. However, when the grinding wheel is working, it needs to rotate continuously and is spirally connected to the connecting structure. In this case, the rotating power may affect the relevant bearings, causing the connection point between the inner shaft of the grinding wheel and the power bearing to gradually loosen, which leads to the need for frequent tightening of the connection parts. However, if it is over-tightened, the rotation of the grinding wheel will become unsmooth, and during disassembly, the grinding wheel will be driven to rotate together due to the effect of friction, thereby increasing the difficulty of disassembly.
