Grinding wheel is the most widely used abrasive tool. It rotates at high speed when used and can be used for rough grinding, semi-finishing grinding, fine grinding, grooving and cutting of the outer circle, inner circle, plane and various surfaces of the workpiece. Grinding wheel can be divided into resin grinding wheel, rubber grinding wheel, metal grinding wheel, ceramic grinding wheel, electroplating coating grinding wheel and single-layer metal coating grinding wheel according to the different types of binders. Resin grinding wheel has high strength, high elasticity, impact resistance and hardness. Due to its solidity and other characteristics, it is widely used. When some double-sided concave resin grinding wheels are used, the double-sided concave resin grinding wheels are first installed on the drive shaft through the mounting hole, and then the drive shaft drives the double-sided concave resin grinding wheel to rotate at a high speed through the power device. The outer grinding surface of the double-sided concave resin grinding wheel rotates at a high speed to grind the surface of the workpiece. However, the double-sided concave resin grinding wheel rotates at a high speed when in use, which will generate a lot of heat. The large amount of heat accumulation will cause cracks in the grinding part of the double-sided concave resin grinding wheel, affecting the service life of the double-sided concave resin grinding wheel.

DETAILED DESCRIPTION
[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0019] See also Figure 1-3 , This embodiment provides a technical solution: a double-sided concave resin grinding wheel that is easy to dissipate heat, including a mounting seat 1;
[0020] Mounting seat 1: a grinding wheel body 3 is provided on its outer side, a water storage shell 5 is provided on the front side of the grinding wheel body 3, uniformly distributed water diversion grooves 7 are provided inside the grinding wheel body 3, the water diversion grooves 7 are connected with the water storage shell 5, a cross 9 and a blocking ring 13 are provided inside the water diversion grooves 7, a telescopic column 10 is provided on the side of the cross 9 close to the center of the mounting seat 1, a blocking seat 12 is provided on the telescopic end of the telescopic column 10, and the blocking seat 12 is installed in coordination with the blocking ring 13, uniformly distributed concave patterns 4 are provided on the front and rear sides of the grinding wheel body 3, a sponge pad 8 is provided at the water outlet of the water diversion groove 7, a spring 11 is provided between the cross 9 and the adjacent blocking seat 12, and the spring 11 is connected to the adjacent The outer end of the telescopic column 10 is movably sleeved, and the front and rear side walls of the grinding wheel body 3 are both provided with evenly distributed thermal conductive silicon chips 14. A water inlet pipe is penetrated through the front wall of the water storage shell 5, and a threaded cover 6 is threadedly connected to the outer front end of the water inlet pipe. Evenly distributed mounting holes 2 are opened on the front side of the mounting seat 1. When using the double-sided concave resin grinding wheel to grind the external workpiece, first, the device is fixed to the rotating shaft with bolts through the mounting hole 2, and then the rotating shaft drives the grinding wheel body 3 to rotate through the external power device. The outer grinding surface of the grinding wheel body 3 rotates at a high speed to grind the surface of the workpiece. When the double-sided concave resin grinding wheel is used to grind the surface of the workpiece, the grinding wheel body 3 The high-speed rotation causes the water in the water storage shell 5 to enter the water diversion groove 7 under the action of centrifugal force and exert centrifugal pressure on the blocking seat 12. The blocking seat 12 is separated from the blocking ring 13 by the centrifugal pressure of the water, thereby releasing the blocking restriction on the water diversion groove 7. The telescopic end of the telescopic column 10 and the spring 11 contract, and then the water flows along the water diversion groove 7 and contacts the sponge pad 8. Through the capillary phenomenon of the sponge pad 8, the water gradually diffuses to the outer surface of the grinding wheel body 3, and the heat is absorbed by the evaporation of the water, thereby dissipating the heat of the grinding part of the double-sided concave resin grinding wheel. The compression elastic force of the spring 11 makes the blocking seat 12 and the blocking ring 13 squeeze and contact when the device is not in use, avoiding this situation. The water inside the device is consumed, and the heat-conducting silicon wafer 14 has excellent heat-conducting performance. The heat-conducting silicon wafer 14 accelerates the heat exchange rate between the inside of the double-sided concave resin grinding wheel and the external gas, and further grinds and dissipates the heat of the double-sided concave resin grinding wheel. It is easy to use. When the device is not in use, the threaded cover 6 is rotated to open, and the water storage shell 5 is replenished with water through the water inlet pipe. The double-sided concave resin grinding wheel that is easy to dissipate heat absorbs heat through water evaporation and accelerates the heat exchange efficiency between the inside of the device and the external gas, thereby efficiently dissipating the heat during the grinding process of the double-sided concave resin grinding wheel, avoiding cracking, and thereby prolonging the service life of the double-sided concave resin grinding wheel.
[0021] The outer side of the grinding wheel body 3 is provided with a diamond grinding layer, and the diamond grinding layer is used to increase the grinding service life of the device itself.
[0022] The working principle of the double-sided concave resin grinding wheel for easy heat dissipation provided by the utility model is as follows: when using the double-sided concave resin grinding wheel to grind an external workpiece, first fix the device to the rotating shaft with bolts through the mounting hole 2, and then use an external power device to make the rotating shaft drive the grinding wheel body 3 to rotate, and the outer grinding surface of the grinding wheel body 3 rotates at high speed to grind the surface of the workpiece. When the double-sided concave resin grinding wheel grinds the surface of the workpiece, the grinding wheel body 3 rotates at high speed, and the water in the water storage shell 5 enters the water diversion groove 7 under the action of centrifugal force and applies centrifugal pressure to the blocking seat 12. The blocking seat 12 is separated from the blocking ring 13 by the centrifugal pressure of the water, thereby releasing the blocking restriction on the water diversion groove 7, and the telescopic end of the telescopic column 10 and the spring 11 contract, and then the water flows along The water inlet groove 7 is in contact with the sponge pad 8. Through the capillary phenomenon of the sponge pad 8, the water gradually diffuses to the outer surface of the grinding wheel body 3, and absorbs heat through evaporation of the water, thereby dissipating the heat of the grinding part of the double-sided concave resin grinding wheel. The compression elastic force of the spring 11 makes the sealing seat 12 and the sealing ring 13 squeeze and contact when the device is not in use, thereby avoiding the consumption of water inside the device at this time. At the same time, the thermal conductive silicon chip 14 has excellent thermal conductivity. The heat exchange rate between the inside and outside of the double-sided concave resin grinding wheel is accelerated through the thermal conductive silicon chip 14, and the double-sided concave resin grinding wheel is further ground and dissipated. It is easy to use, and the grinding service life of the device itself is increased through the diamond grinding layer. When the device is not in use, the threaded cover 6 is rotated to open, and the water in the water storage shell 5 is replenished with water through the water inlet pipe.
