Description

Technical Field

[0001] The utility model relates to the technical field of grinding wheel polishing, in particular to a special grinding wheel for nuclear power. Background Art

[0002] Grinding with a grinding wheel is a process that uses a grinding wheel to remove materials and perform surface processing. In the process of manufacturing nuclear power equipment, special grinding wheels for nuclear power are needed to process, grind and polish the surface or interior of the equipment.

[0003] However, the existing nuclear power-specific grinding wheels have weak protection functions. When the bowl-type grinding wheels are used for grinding, it is not convenient to perform multi-layer reinforcement and protection work on the bowl-type grinding wheels, which reduces the practicality of the bowl-type grinding wheels. Moreover, the existing nuclear power-specific grinding wheels have weak cooling functions. The bowl-type grinding wheels will continue to generate high temperatures when working, and the accumulation of high temperatures may affect the stability of the bowl-type grinding wheels during operation.

[0007] Preferably, an external groove is provided in the middle of the top surface of the connecting piece, and a protective ring is fixedly connected to the top of the external groove.

[0008] Preferably, the drip assembly further comprises a connecting pipe, the bottom of the connecting pipe is connected to one end of the top of the drip tank, and the top of the connecting pipe is connected to the bottom of the water inlet.

[0009] Preferably, a sponge layer is fixedly connected to one side of the bottom of the drip box, a conical tube is connected through one side of the bottom of the drip box, and buffer blocks are fixedly connected to both ends of the inside of the conical tube.

[0010] Preferably, the protection component further comprises a titanium nitride coating, the interior of the titanium nitride coating is fixedly connected to the surface of the diamond coating, and the surface of the titanium nitride coating is fixedly connected to a silicon carbide coating.

[0011] Preferably, the surface of the silicon carbide coating is fixedly connected to an aluminum oxide coating, and the surface of the aluminum oxide coating is fixedly connected to a zirconium oxide coating.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. This nuclear power-specific grinding wheel has a protective component and a protective ring. When the bowl-shaped grinding wheel is grinding a nuclear power device, the external power equipment is connected to the bowl-shaped grinding wheel through an external groove. The protective ring reinforces and protects the connection between the external power equipment and the external groove to prevent the bowl-shaped grinding wheel from shaking and deviation during operation. The diamond coating, titanium nitride coating, silicon carbide coating, aluminum oxide coating and zirconium oxide coating in the protective component will provide multi-layer and multi-functional reinforcement and protection to the surface of the bowl-shaped grinding wheel, thereby improving the practicality of the bowl-shaped grinding wheel.

[0014] 2. This nuclear power-specific grinding wheel is equipped with a drip assembly, a closing cover and a water inlet. When in use, the staff unscrews the closing cover with a thread and then connects the external water source and the water inlet. The water will flow through the water inlet to the inside of the connecting pipe and to the inside of the drip box. The drip box stores the water, and the sponge layer contacts and absorbs the water. When the bowl-shaped grinding wheel rotates, the water inside the sponge layer will be thrown out and continuously absorb the water inside the drip box. The thrown-out water will pass through the inside of the tapered tube and flow out to the outside. The outflowing water will contact the inside of the bowl-shaped grinding wheel and cool the water inlet of the bowl-shaped grinding wheel, thereby achieving the effect of improving the stability of the bowl-shaped grinding wheel.
