Description

Technical Field

[0001] This utility model relates to the field of diamond grinding wheel technology, specifically a diamond grinding wheel that facilitates the guidance of cooling water. Background Technology

[0002] Diamond grinding wheels are circular bonded abrasive tools with a central through-hole, made from diamond abrasive as the raw material and using metal powder, resin powder, ceramic, and electroplated metal as binders. During grinding, diamond grinding wheels generate extremely high temperatures (above 500 degrees Celsius), with the contact point with the workpiece reaching thousands of degrees Celsius. Therefore, cooling water is required to cool the diamond grinding wheels.

[0003] When existing diamond grinding wheels come into contact with cooling water, the centrifugal force of the wheels causes the cooling water to be thrown away, thereby reducing the cooling effect of the cooling water on the contact point between the diamond grinding wheel and the workpiece. This compromises the service life of the diamond grinding wheel and has certain adverse effects on its use. To address this, we propose a diamond grinding wheel that facilitates the guidance of cooling water. Utility Model Content

The outer surface of the diamond grinding wheel body 1 is provided with a flow guiding structure 2. The flow guiding structure 2 includes a side flow guiding spiral groove 3, a liquid storage through hole 4 and a U-shaped flow storage groove 5. An automatic water spraying auxiliary cooling and reflux device 6 for reducing cooling water splashing is provided above the diamond grinding wheel body 1.

[0022] The side guide spiral groove 3 penetrates the middle of the outer surface of both sides of the diamond grinding wheel body 1, the liquid storage through hole 4 penetrates the middle of the inner surface of both sides of the diamond grinding wheel body 1, and the U-shaped storage groove 5 penetrates the end face of the diamond grinding wheel body 1.

[0023] The automatic water spray-assisted cooling and reflux device 6 includes a mounting base 7. An arc-shaped guide plate 8 is provided on the lower inner surface of the mounting base 7. A flow-blocking and deflecting plate 9 is fixedly connected to the other end of the arc-shaped guide plate 8. A liquid storage tank 10 is fixedly installed on the upper outer surface of the mounting base 7. A high-pressure water pump 11 is fixedly installed on one outer surface of the arc-shaped guide plate 8. A suction pipe 12 is provided between the inlet of the high-pressure water pump 11 and the inside of the liquid storage tank 10. A connecting pipe 13 is fixedly connected to the outlet of the high-pressure water pump 11. A coolant nozzle 14 is provided at the other end of the connecting pipe 13.

[0024] The arc-shaped guide plate 8 is fixedly connected to the lower inner surface of the mounting base 7, and the flow-blocking and deflecting plate 9 is fixedly connected to the other end of the arc-shaped guide plate 8.

The coolant nozzle 14 sprays the cooling water onto the diamond grinding wheel body 1 to cool it down. Under the centrifugal force of the rotating diamond grinding wheel body 1, the cooling water is thrown into the arc-shaped guide plate 8, and finally blocked and refracted by the flow-blocking and refraction plate 9, and then the cooling water in the arc-shaped guide plate 8 is further... The cooling water is guided to the diamond grinding wheel body 1 to avoid splashing. The side guide spiral groove 3 can guide and absorb the cooling water to the two sides of the diamond grinding wheel body 1 for cooling.
