Description

Technical Field

[0001] The utility model relates to the technical field of boron grinding wheels, and more specifically to a combined high-efficiency grinding cubic boron nitride grinding wheel. Background Art

[0002] Cubic boron nitride grinding wheel is a grinding wheel made of cubic boron nitride material. It has high hardness, thermal stability and chemical inertness, as well as excellent properties such as good infrared transmittance and wide bandgap width. Its hardness is second only to diamond. Boron grinding wheel made of cubic boron nitride can not only process difficult-to-grind materials and improve productivity, but also effectively improve the grinding quality of workpieces.

[0003] However, the replacement of existing cubic boron nitride grinding wheels when worn is relatively cumbersome, which will affect the efficiency of grinding work.

[0004] After searching, a Chinese patent with patent publication number CN210704351U discloses a combined high-efficiency grinding cubic boron nitride grinding wheel. The structure is provided with a first cubic boron nitride grinding wheel and a second cubic boron nitride grinding wheel which are spirally engaged with each other. Through the portable combined disassembly and assembly operation therebetween, the worn-out first cubic boron nitride grinding wheel can be replaced in time, and the processing tool can be directly ground by the second cubic boron nitride grinding wheel, making the grinding work more efficient.

[0005] However, when the structure is actually used, when the second cubic boron nitride grinding wheel of the structure is connected to the metal fixing ring, according to the attachment of the structure, Figure 1 As shown, the bolt needs to be spirally inserted into the threaded through hole corresponding to the groove and the threaded groove of the second cubic boron nitride grinding wheel to fix the second cubic boron nitride grinding wheel to the metal fixing ring. However, during the installation or disassembly process, a disassembly tool such as a wrench or a screwdriver is required, and the space inside the metal fixing ring is limited. During the disassembly, the disassembly tool needs to be operated inside the fixing ring, which is inconvenient. In view of this, the utility model proposes a combined high-efficiency grinding cubic boron nitride grinding wheel. Utility Model Content
