The experimental methods in the following embodiments are conventional methods unless otherwise specified, and the materials, reagents, etc. used in the following embodiments are all commercially available unless otherwise specified.

[0020] Embodiment 1:

[0021] like Figure 1-Figure 4 As shown, a polishing wheel that is easy to disassemble includes a motor 1 and a connecting mechanism, wherein the connecting mechanism includes a connecting rotating member 11, the connecting rotating member 11 is transmission-connected to the output end of the motor 1, a polishing wheel 2 is movably connected to the outer side of the connecting rotating member 11, a connecting thread groove 14 is provided on one end surface of the connecting rotating member 11, the inner side of the polishing wheel 2 is movably connected to a limited connecting member 3, one end of the limited connecting member 3 is movably connected to the outer side of the polishing wheel 2, a movable groove 31 is provided inside the limited connecting member 3, a main rotating rod 32 is connected to the inner bearing of the movable groove 31, a driving gear 33 is provided on the outer side of the main rotating rod 32, and a gear 33 is provided on the outer side of the driving gear 33. The driven gear 34 is connected to the main rotating rod 32, and a connecting screw 35 is provided inside the driven gear 34. One end of the connecting screw 35 passes through the limiting connecting piece 3 and is threadedly connected to the inner side of the connecting thread groove 14. One end of the main rotating rod 32 passes through the limiting connecting piece 3 and is located outside the limiting connecting piece 3 and is fixedly connected to an auxiliary rotating block 36. A positioning component is provided between the auxiliary rotating block 36 and the limiting connecting piece 3. The positioning component includes a positioning rotating block 37, which is provided on a side surface of the auxiliary rotating block 36 close to the limiting connecting piece 3. A positioning rotating groove 38 is provided outside the limiting connecting piece 3, and the positioning rotating block 37 is rotatably connected to the inner side of the positioning rotating groove 38.

[0022] Polishing refers to a processing method that uses mechanical, chemical or electrochemical effects to reduce the surface roughness of a workpiece to obtain a bright and smooth surface. It is a modification process of the workpiece surface using polishing tools and abrasive particles or other polishing media. Among them, the most important part of polishing is the polishing wheel, which will wear out during the polishing operation and is a consumable that needs to be replaced regularly.

[0023] The polishing wheels on the existing polishing devices are usually connected by bolts, which is the most stable method. In order to improve the stability, multiple bolts are used to complete the connection. However, when disassembling and assembling, these bolts need to be disassembled and assembled one by one using tools, which is cumbersome and involves too many steps.

[0024] When the polishing wheel 2 needs to be replaced, the auxiliary rotating block 36 is first rotated to allow the auxiliary rotating block 36 to drive the main rotating rod 32 so that the driving gear 33 rotates. While the driving gear 33 rotates, multiple driven gears 34 around it rotate together, so that the connecting screw 35 rotates to leave the connecting thread groove 14 until the limiting connecting member 3 is completely separated from the connecting rotating member 11. The limiting connecting member 3 can be removed first, and then the old polishing wheel 2 is removed. Then, the new polishing wheel 2 is put on the connecting rotating member 11, and then one end of the limiting connecting member 3 is inserted into the inner side of the polishing wheel 2 and the position of the connecting screw 35 corresponds to the connecting thread groove 14. Then, the auxiliary rotating block 36 is rotated in the opposite direction. Through a series of drives, the connecting screw 35 rotates in the opposite direction and slowly enters the inner side of the connecting thread groove 14 to complete the connection between the polishing wheel 2 and the connecting rotating member 11.

[0025] When replacing the polishing wheel 2, multiple connecting screws 35 can be rotated at one time to complete the disassembly and assembly of the polishing wheel 2. This can improve the convenience of disassembly of the polishing wheel 2 without affecting the installation stability of the polishing wheel 2. At the same time, there is no need to carry additional disassembly and assembly tools, and the burden and preconditions during operation are less, achieving a burden-reducing effect.

[0026] In other embodiments, the present embodiment discloses, please Figure 3 As shown, a rubber ring 30 is provided on one side of the limiting connector 3 close to the polishing wheel 2, and the rubber ring 30 is movably connected to the outer side of the polishing wheel 2; through this design, the friction between the limiting connector 3 and the polishing wheel 2 is greater and will not be damaged due to friction.

[0027] In other embodiments, the present embodiment discloses, please Figure 2 As shown, the polishing wheel 2 includes a main body 21 and a polishing body 22, wherein the main body 21 is located on the inner side and the polishing body 22 is located on the outer side of the main body 21; through this design, the structure of the polishing wheel 2 is more perfect, and at the same time, the connected components are all arranged on the main body 21, which will not affect the normal use of the polishing body 22.

[0028] Embodiment 2:

[0029] In other embodiments, the present embodiment discloses, please Figure 1-Figure 3 As shown, it also includes a reinforcement mechanism, which includes a fixing ring 12, the fixing ring 12 is arranged on one end surface of the motor 1, and the other end surface of the fixing ring 12 is provided with a first buffer cotton 13, and a connection slot 23 is opened on the surface of the side of the polishing wheel 2 close to the motor 1, one end of the fixing ring 12 is plugged into the inner side of the connection slot 23, and a second buffer cotton 24 is provided inside the connection slot 23, and the second buffer cotton 24 is movably connected to the first buffer cotton 13;

[0030] When the polishing wheel 2 is sleeved on the connecting rotating part 11, the fixing ring 12 is inserted into the connecting slot 23 to ensure that the position of the polishing wheel 2 is normal, and then the operation of the connecting mechanism is continued. If the polishing wheel 2 is squeezed during operation, the second buffer cotton 24 and the first buffer cotton 13 will not cause the components to be damaged due to squeezing; the connection point between the polishing wheel 2 and the motor 1 can be improved, thereby improving the stability during installation and avoiding displacement or misalignment of the polishing wheel 2 during installation.

[0031] The implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
