[0035] As attached Figure 1 To Attachment Figure 2 As shown:

[0036] The present invention provides a grinding wheel, comprising:

[0037] The detachable grinding wheel component 1 includes a base plate 15, a magnet 14 fixedly connected to one end surface of the base plate 15, an iron plate 12 magnetically connected to the magnet 14, a grinding wheel 11 fixedly connected to the iron plate 12, and a transmission rod 17 fixedly connected to the other end surface of the base plate 15.

[0038] In this embodiment, the grinding wheel 11 is designed to be a magnetic structure, which facilitates the installation and replacement of the grinding wheel 11 and improves the convenience of installation.

[0039] An outer protective ring 16 is arranged on the periphery of the magnet 14, and the outer protective ring 16 is fixedly connected to the bottom plate 15. The outer protective ring 16 plays a protective role on the magnet.

[0040] At least one avoidance notch 160 is provided on the outer periphery of the outer protection ring 16. The avoidance notch 160 is provided to facilitate the removal of the grinding wheel 11 by hand.

[0041] Embodiment 2:

[0042] like Figures 3 to 6 As shown, the remaining features of this embodiment are the same as those of the first embodiment, except that the detachable grinding wheel component 1 in this embodiment further includes a heat absorbing ring 13, which is fixedly connected to the bottom plate 15, and the heat absorbing ring 13 can be in thermal contact with the iron plate 12;

[0043] It also includes a heat absorbing rotating member 2, which includes an inner ring shell 21 and an outer ring shell 22 arranged on the outer periphery of the inner ring shell 21, the inner ring shell 21 includes a first bottom shell 211, a first top cover 212 rotatably connected to the top of the first bottom shell 211, a first flow guide pipe 213 connected to the inside of the first bottom shell 211 at one end, and a first outer pipe port 214 connected to the inside of the first top cover 212, the other end of the first flow guide pipe 213 is connected to the inside of the heat absorbing tube ring 13, and the first bottom shell 211 and the first top cover 212 form a first cavity;

[0044] The outer ring shell 22 includes a second bottom shell 221, a second top cover 222 rotatably connected to the top of the second bottom shell 221, a second flow guide pipe 223 connected to the inside of the second bottom shell 221 at one end, and a second outer pipe opening 224 connected to the inside of the second top cover 222 at one end. The other end of the second flow guide pipe 223 is connected to the heat absorbing tube ring 13. The second bottom shell 221 and the second top cover 222 form a second cavity.

[0045] A sealing ring 3 is provided at the connection between the first bottom shell 211 and the first top cover 212 , and a sealing ring 3 is also provided at the connection between the second bottom shell 221 and the second top cover 222 .

[0046] In this embodiment, a heat absorbing rotating member 2 is provided to cool the grinding wheel 11, thereby extending the service life and high temperature resistance of the grinding wheel.

[0047] The second outer pipe opening 224, the outer ring shell 22, the second flow guide pipe 223, the heat absorbing tube ring 13, the first flow guide pipe 213, the inner ring shell 21, the first outer pipe opening 214

[0048] The sealing ring 3 is a lip-shaped oil seal for the rotating shaft. The lip-shaped oil seal for the rotating shaft, also known as a skeleton oil seal, works on the basis of an oil film controlled by the oil seal edge, and the oil film has fluid lubrication properties. Under the action of the surface tension of the liquid, the stiffness of the oil film causes the oil film to form a crescent surface at the contact end with the air, thereby preventing leakage of the working medium, thereby achieving sealing of the rotating shaft. It has good sealing performance, thereby forming a good fluid flow space, and ensuring the mutual rotation of the first bottom shell 211 and the first top cover 212, and the mutual rotation of the second bottom shell 221 and the second top cover 222.

[0049] The first bottom shell 211 and the second bottom shell 221 are fixedly connected to the bottom plate 15, so that the structures of the first bottom shell 211 and the second bottom shell 221 are stable.

[0050] At least one limiting rod 110 is fixedly connected to the bottom plate 15 , and both the grinding wheel 11 and the iron plate 12 are provided with through holes corresponding to the limiting rod 110 .

[0051] The limit rod 110 is made of non-magnetic material to ensure that the through holes of the grinding wheel 11 and the iron plate 12 are adsorbed by the magnet 14 after being inserted into the limit rod 110 to avoid the magnetic attraction from affecting the positioning of the iron plate 12. The limit rod 110 is made of plastic or aluminum alloy.

[0052] Embodiment three:

[0053] The remaining features are the same as those of the second embodiment, except that the sealing ring 3 in this embodiment is a high temperature resistant spring tension sealing ring. The sealing ring provides a certain sealing effect through spring tension and can withstand high temperature environments, further improving the high temperature working reliability of the sealing ring.

[0054] The specific usage and function of this embodiment are as follows:

[0055] When the present invention is in use, the first top cover 212 and the second top cover 222 are fixedly arranged so that the first bottom shell 211 and the first top cover 212 can rotate with each other, and the second bottom shell 221 and the second top cover 222 can rotate with each other, so that when the grinding wheel is running, heat exchange can be carried out with the outside world, so that the cooling performance of the grinding wheel 11 is better, and the first outer pipe opening 214 is injected with coolant, and the coolant flows through the inner ring shell 21, the first guide pipe 213, the heat absorbing tube ring 13, the second guide pipe 223, the outer ring shell 22 in sequence, and then flows out from the second outer pipe opening 224, and the heat generated by the grinding wheel 11 is transferred to the iron plate 12 and the heat absorbing tube ring 13, and the heat is transferred from the heat absorbing tube ring 13 to the coolant.

[0056] The embodiments of the present invention are given for the purpose of illustration and description, and are not intended to be exhaustive or to limit the invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art.
