[0044] Combined with Figures 1 to 11 As shown, a superhard grinding wheel that is easy to replace includes a superhard grinding wheel body 1 and a disassembly component 2.

[0045] A first mounting cavity 11 is formed on the superhard grinding wheel body 1, and a plurality of through holes 12 are also formed on the superhard grinding wheel body 1. The through holes 12 are located around the first mounting cavity 11; a disassembly component 2 is provided on the superhard grinding wheel body 1 to facilitate the replacement of the superhard grinding wheel body 1; the disassembly component 2 includes: a first mounting plate 21, a second mounting plate 22 and a connection component 23. The first mounting plate 21 is sleeved on one side of the first mounting cavity 11; the second mounting plate 22 is sleeved on the other side of the first mounting cavity 11, and the second mounting plate 22 is arranged opposite to the first mounting plate 21; the connection component 23 is arranged in the through hole 12, and one end of the connection component 23 is fixedly connected to the first mounting plate 21, and the other end of the connection component 23 is detachably connected to the second mounting plate 22.

[0046] Among them, under the action of the disassembly component 2 and by using the first mounting plate 21, the second mounting plate 22 and the connection component 23 for connection, the fixation and disassembly of the superhard grinding wheel body 1 are realized. The structure is simple and the operation is convenient, achieving the effect of quickly and conveniently disassembling and installing the superhard grinding wheel body 1, greatly shortening the time for replacing the grinding wheel, improving the work efficiency, and at the same time avoiding the situation of overall replacement of the device due to the wear or failure of a single grinding wheel. The first mounting cavity 11 and the through holes 12 on the superhard grinding wheel body 1 are key structures, which provide mounting positions for the disassembly component 2. The disassembly component 2 is composed of the first mounting plate 21, the second mounting plate 22 and the connection component 23. The first mounting plate 21 and the second mounting plate 22 are respectively sleeved on both sides of the first mounting cavity 11 to form a stable support structure. The connection component 23 passes through the through hole 12, one end is fixed on the first mounting plate 21, and the other end is detachably connected to the second mounting plate 22, such as threaded connection or snap connection, etc. Such a design enables that when the grinding wheel needs to be replaced, only the connection component 23 needs to be loosened, and the second mounting plate 22 together with the worn grinding wheel can be separated from the first mounting plate 21, then a new grinding wheel is replaced, and the connection component 23 is fixed again to complete the replacement process.

[0047] Combined with Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 7As shown, a second mounting cavity 221 corresponding to the through hole 12 is provided on the second mounting plate 22. The connecting component 23 passes through the through hole 12 and extends into the second mounting cavity 221. The connecting component 23 includes: a connecting rod 231, a spring 234, and a limiting head 235. One end of the connecting rod 231 is fixedly connected to the first mounting plate 21, and the other end passes through the through hole 12 and extends into the second mounting cavity 221. Guide grooves 232 are respectively formed on both sides of the connecting rod 231 extending into the second mounting cavity 221, and a limiting groove 233 is formed on one side of the guide groove 232; The spring 234 is arranged on both side walls of the second mounting cavity 221, one end of the spring 234 is fixedly connected to the inner side wall of the second mounting cavity 221, the other end of the spring 234 is fixedly connected to a limiting head 235, a limiting convex block 236 is fixedly arranged on one side of the limiting head 235, and the limiting convex block 236 is slidably arranged in the guide groove 232 and is embedded in the limiting groove 233; Accommodating cavities 222 are respectively formed on both side walls of the second mounting cavity 221, and the spring 234 is embedded in the accommodating cavity 222.

[0048] Specifically, the second mounting cavity 7 on the second mounting plate 6 corresponds to the through hole 3, and the connecting component 4 enters the second mounting cavity 7 through the through hole 3. One end of the connecting rod 9 is fixed to the first mounting plate 5, and the other end moves in the second mounting cavity 7 through the guide groove 232 and the limiting groove 233. The spring 10 is located in the accommodating cavities 222 on both side walls of the second mounting cavity 7, one end of it is fixed to the inner side wall, the other end is connected to the limiting head 11, and the limiting convex block 12 on the limiting head 11 slides in the guide groove 232 and is embedded in the limiting groove 233, ensuring the stability and safety of the connecting component 4. Such a design ensures that the connecting component 4 will not accidentally come out during the disassembly and assembly process. The elastic force of the spring 10 provides a certain pre-tightening force and can automatically rebound during disassembly, making the process of replacing the super-hard grinding wheel body 1 more convenient and fast. The existence of the accommodating cavity 222 protects the spring 10 from being interfered during work, ensuring the stability and reliability of the entire system.

[0049] Specifically, the number of the second mounting cavities 221 is the same as that of the through holes 12. The guide grooves 232 are inclined, and the guide grooves 232, the limiting grooves 233, and the limiting convex blocks 236 are all rectangular structures.

[0050] Among them, the number of the second installation cavities 221 is consistent with that of the through holes 12, ensuring that the connection components 23 can accurately correspond to each through hole on the superhard grinding wheel body 1, and improving the installation accuracy. The guiding groove 232 is inclined, which plays a guiding role during the installation and disassembly processes. When the connection component 23 is inserted or removed, the inclined guiding groove 232 guides the limiting convex block 236 to move in a specific direction. At this time, due to the action of the inclined guiding groove 232, the limiting convex block 236 will drive the limiting head 235 to push the spring 234 to move towards the accommodating cavity 222, and the spring 234 will be in a compressed state until the limiting convex block 236 completely enters the limiting groove 233. That is, under the action of the spring 234, the first mounting plate 21 and the second mounting plate 22 are completed, and the superhard grinding wheel body 1 is mounted on the disassembly component 2. Moreover, under the action of the spring 234, the loosening between the first mounting plate 21 and the second mounting plate 22 is also avoided. The design of the guiding groove 232, the limiting groove 233, and the limiting convex block 236 with a rectangular structure provides precise positioning and locking for the connection component 23. When the limiting convex block 236 slides along the guiding groove 232 to the limiting groove 233, the two fit tightly to form a firm locking state, ensuring the stable fixation of the connection component 23 on the second mounting plate 22. Compared with other shapes, the rectangular structure provides a larger contact area, increases the friction force, helps prevent the connection component 23 from sliding or loosening during operation, and enhances the overall stability.

[0051] Combined with Figure 1 、 Figure 2 and Figure 8 as shown, a sealing cover 3 is sleeved on one side of the second installation cavity 221. Among them, the sealing cover 3 is sleeved on the second installation cavity 221, which not only ensures the beauty of the whole device, but also the socket of the sealing cover 3 just abuts against the end of the connecting rod 231. Besides ensuring the positioning of the connecting rod 231, it can also prevent the connecting rod 231 from loosening.

[0052] Combined with Figure 9 as shown, a sleeve 24 is fixedly arranged on one side of the first mounting plate 21, and a plurality of mounting holes 241 are formed in the sleeve 24, so that under the action of the sleeve 24 and the mounting holes 241, the whole device can be fixedly sleeved on the rotating shaft of the corresponding equipment.

[0053] Combined with Figure 9 and Figure 10 as shown, arc-shaped grooves 211 are respectively formed on both sides of the first mounting plate 21, and a pull rod 212 is rotatably arranged in the arc-shaped grooves 211. When replacing the superhard grinding wheel body 1, the separation between the first mounting plate 21 and the second mounting plate 22 can be realized under the action of the pull rod 212. At the same time, under the action of the arc-shaped grooves 211, the pull rod 212 can be freely stored in the arc-shaped grooves 211.

[0054] Combined with Figure 10 As shown, limit pieces 213 are fixedly arranged on both sides of the arc-shaped groove 211 respectively, the pull rod 212 is embedded between the two limit pieces 213, and the limit pieces 213 are made of rubber material.

[0055] Among them, under the action of the two limit pieces 213, when not in use, the pull rod 212 can be completely fixedly placed in the arc-shaped groove 211. When in use, since the limit pieces 213 are made of rubber material, the limit pieces 213 will produce a certain elastic deformation, so as to realize the effect that the pull rod 212 can rotate relative to the arc-shaped groove 211.

[0056] The embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, various changes can also be made without departing from the gist of the present invention.
