[0002] Existing grinding wheels, also known as bonded abrasives, are tools used to grind cutting tools or parts. They are made by bonding ordinary abrasive grains into a certain shape (mostly circular with a central through hole) with a bonding agent, and possess a certain strength.

[0003] Existing grinding wheels and their internal mounting structures are all integrally formed and fixed during manufacturing, which is not convenient for separate operation. When the grinding wheel is damaged by friction after long-term operation, the whole wheel becomes unusable, making it difficult to replace parts and causing material waste. This also affects the convenience of separate disassembly and replacement when the grinding wheel is damaged after installation. Therefore, this utility model proposes a separate grinding wheel structure. Utility Model Content

[0025] To facilitate the installation of the four-corner post mount 1011 and the inner four-corner chuck 1016 using the mounting assembly, in this embodiment, preferably, the mounting assembly includes an embedding groove 1012 located at the middle position of both sides of the grinding wheel body 101. The connection point of the two embedding grooves 1012 is located inside the grinding wheel body 101 and forms a four-corner locking hole 1018. The four-corner post mount 1011 and the inner four-corner chuck 1016 can be installed through the embedding grooves 1012, and when the four-corner post mount 1011 is installed, it extends through the four-corner locking hole 1018 to the inner surface of the inner four-corner chuck 1016.

[0026] To facilitate the installation of the four-corner post mount 1011 and the inner four-corner chuck 1016 via a fixed connection assembly, in this embodiment, preferably, the fixed connection assembly includes a four-corner post mount 1011 that is engaged with one side of the grinding wheel body 101 via an embedding groove 1012, and an inner four-corner chuck 1016 that is engaged with the other side of the grinding wheel body 101 via an embedding groove 1012. The four-corner post mount 1011 passes through the four-corner locking holes 1018 and the interior of the inner four-corner chuck 1016, and the end surface of the four-corner post mount 1011 is flush with the surface of the inner four-corner chuck 1016. After the four-corner post mount 1011 and the inner four-corner chuck 1016 are installed via the embedding groove 1012, the four-corner post mount 1011 can be installed and used by passing through the four-corner locking holes 1018 and the interior of the inner four-corner chuck 1016, which facilitates installation and, conversely, facilitates separate replacement.

[0027] In order to facilitate the through-mounting of the threaded rod 1014 when installing the four corner post mounting body 1011 and the inner four corner chuck 1016, in this embodiment, preferably, the through-mounting component includes a through hole 1019 formed between the edges of the two embedded grooves 1012, and four grooves 1015 are formed on the surface edge of the four corner post mounting body 1011, so that the threaded rod 1014 can pass through the through hole 1019 and the grooves 1015 when the inner four corner chuck 1016 is closed for installation.

[0028] To facilitate the installation and fixation of the four-corner post mounting body 1011 and the inner four-corner chuck 1016 by means of a rotating fixing assembly, in this embodiment, preferably, the rotating fixing assembly includes a threaded rod 1014 integrally disposed at the edge of the inner surface of the inner four-corner chuck 1016. The threaded rod 1014 passes through the through hole 1019 and the interior of the groove 1015. The bottom end of the threaded rod 1014 is located inside the groove 1015 and is threadedly connected to a fixing nut 1013. The threaded rod 1014 can be passed through the four-corner post mounting body 1011 and the inner four-corner chuck 1016, and the fixing nut 1013 can be rotated on the bottom surface of the threaded rod 1014 to fix it, which facilitates the reinforcement and installation.

[0029] The heat dissipation mechanism includes a heat dissipation and chip removal component located at the edge of the outer surface of the grinding wheel body 101. During the grinding process, the heat dissipation mechanism increases the contact with air on the outer surface of the grinding wheel body 101 to dissipate heat, while facilitating chip removal during heat dissipation.

[0030] In order to facilitate heat dissipation and chip removal by increasing the contact between the outer surface of the grinding wheel body 101 and the air, the heat dissipation and chip removal assembly is preferably provided in this embodiment. It includes heat dissipation grooves 1017 formed at equal intervals at the edge of the outer surface of the grinding wheel body 101, and the cross-section of the heat dissipation grooves 1017 is V-shaped. During the grinding process of the grinding wheel body 101, the heat dissipation grooves 1017 can increase the contact with the air for rapid heat dissipation, and chip removal is performed at both ends of the heat dissipation grooves 1017 during heat dissipation.

[0031] The working principle and usage process of this utility model: Before use, this split-type grinding wheel structure is first installed. The four corner post mounting bodies 1011 and the inner four-corner chucks 1016 are engaged through the embedding grooves 1012 on both sides of the grinding wheel body 101. This continues until the four corner post mounting bodies 1011 pass through the four corner locking holes 1018 and the inner four-corner chucks 1016 are closed. When the inner four-corner chucks 1016 are closed, the threaded rod 1014 extends through the through hole 1019 into the interior of the groove 1015. The fixing nut 1013 is rotated to the bottom end of the threaded rod 1014 to fix it, so that both the end of the threaded rod 1014 and the fixing nut 1013 are embedded in the interior of the groove 1015, facilitating... The inner four-corner chuck 1016 is fixedly installed with the four-corner column mounting body 1011 and the grinding wheel body 101. When in use, the output shaft of the grinding wheel machine drive end is directly inserted through the interior of the four-corner column mounting body 1011 for fixed installation. This facilitates the assembly and installation of the grinding wheel body 101 and its subsequent fixed installation with the drive end for processing operations. Therefore, if the grinding wheel body 101 is damaged after long-term grinding after installation, the inner four-corner chuck 1016 and the four-corner column mounting body 1011 can be disassembled and the grinding wheel body 101 replaced in reverse order. This facilitates partial replacement of the grinding wheel body 101, avoids material waste, and improves the convenience of disassembly and replacement of the grinding wheel body 101 when it is damaged after installation.

[0032] Then, when the grinding wheel body 101 is fixedly installed on the output shaft of the drive end of the grinding machine through the four corner column mounting body 1011 and the inner four corner chuck 1016 for grinding, when the surface of the grinding wheel body 101 generates heat, the heat dissipation groove 1017 increases the contact area between the surface of the grinding wheel body 101 and the air, and effectively dissipates heat when in contact with the air during grinding. The debris generated during grinding is discharged from the side of the heat dissipation groove 1017, which facilitates heat dissipation and chip removal, and improves the convenience of surface heat dissipation and chip removal of the grinding wheel body 101 after installation.

[0033] Although embodiments of the present invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
