DETAILED DESCRIPTION

[0024] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0025] like Figure 1-6 As shown, a grinding tool for preparing porous carbon materials includes an abrasive handle 1 for an operator to hold or install on a movable arm. The abrasive handle 1 has a built-in drive assembly 2 to provide driving torque. The drive assembly 2 is connected to a grinding disc 3. The grinding disc 3 is connected to an abrasive sheet 5 through a locking assembly 4. When the grinding disc 3 rotates, the abrasive sheet 5 rotates synchronously therewith. An adapter assembly 6 and a cover assembly 7 that hides the adapter assembly 6 are installed on the abrasive handle 1. The assembly and wiring control requirements of the abrasive handle 1 can be achieved by plugging and fixing. The abrasive handle 1 is connected to a guide assembly 8 adjacent to the grinding disc 3. When the abrasive tool moves to grind the porous carbon material, the guide assembly 8 contacts the surface of the material to detect its relative position in time to avoid excessive movement of the abrasive tool to damage the carbon material.

[0026] Specifically, in order to facilitate the gripping operation of the abrasive handle 1, it specifically includes a main handle body 11, a side of the main handle body 11 is provided with an integrally formed auxiliary handle body 12, and an extension handle 13 rotatably connected to the grinding disc 3 is provided at the end of the main handle body 11. The drive assembly 2 is arranged inside the abrasive handle 1 and is transmission-connected to the grinding disc 3 along the extension handle 13.

[0027] In depth, similar to the existing drive structure, the drive assembly 2 in the present application includes a drive motor 21 installed inside the main handle body 11, and the drive motor 21 is a variable frequency motor and can adjust the output power according to the abrasive sheet 5. The auxiliary handle body 12 has a built-in power module 22 and a main control module 23. A switch module 24 is provided at the junction of the main handle body 11 and the auxiliary handle body 12. The main control module 23 is controlled by external wiring to realize the automatic grinding of the abrasive tool. The extension handle 13 has a built-in speed change gear set 25 that is transmission-connected to the drive motor 21, and a connecting rod structure can also be used for transmission.

[0028] Furthermore, a protective cover plate 14 covering the grinding disc 3 is installed at the extension handle 13 of the abrasive handle 1, and a protective baffle plate 15 circumferentially opposite to the grinding disc 3 is arranged at the edge of the protective cover plate 14. The protective cover plate 14 and the protective cover plate 14 cooperate to form a disc body structure to prevent debris from splashing during grinding.

[0029] Furthermore, the adapter assembly 6 mainly meets the functions of fixing the position of the mold and power supply, and includes an adapter socket 61 arranged at the end of the main handle body 11, the adapter socket 61 has an internal adapter step surface 62, and a limit groove 63 is arranged between the adapter step surface 62 and the adapter socket 61. The corresponding robot arm has a plug plugged into the adapter socket 61, and the internal limit groove 63 is equipped with a charging contact. A wiring jack 64 is opened at the end of the auxiliary handle body 12 to realize the connection of the external control line.

[0030] In addition, in order to prevent external foreign matter from invading the adapter assembly 6, the cover assembly 7 closes the adapter assembly 6, including a closing plate 71 rotatably installed at the end of the main handle body 11, an elastic element is installed between the closing plate 71 and the main handle body 11, and the wiring hole 64 is blocked by a closing block 72 made of elastic material.

[0031] At the same time, unlike the conventional assembly structure of the abrasive sheet 5, the grinding disc 3 in the present application includes a main disc body 31, a spline hole 32 is opened in the center of the main disc body 31 for center limiting, spiral reinforcement ribs 33 are distributed on the main disc body 31 to provide its circumferential rotation structural stability, and the main disc body 31 has an assembly hole 34 arranged in a central symmetric manner relative to the spline hole 32, which is locked and fixed with the abrasive sheet 5 through a screw. The assembly hole 34 is equipped with an assembly gasket 35, and the distance between the locking assembly 4 and the main disc body 31 is adjusted by adjusting the specifications and quantity of the assembly gasket 35.

[0032] It can be seen that the locking assembly 4 includes a locking disk 41, which is connected to the assembly hole 34 of the main disk body 31 through a screw, a locking hole 42 is opened in the center of the locking disk 41, and mutually meshing locking teeth 43 are arranged between the locking disk 41 and the abrasive sheet 5. After the locking disk 41 is fitted with the abrasive sheet 5, the locking teeth 43 are engaged to achieve circumferential limiting, and the abrasive sheet 5 will not loosen or separate when it rotates at high speed.

[0033] Obviously, the guide assembly 8 includes a guide seat 81 clamped and fixed on the abrasive handle 1, and the guide seat 81 is connected to a guide roller 83 through a telescopic connecting rod 82, and a pressure sensor is installed on the guide roller 83. The guide seat 81 can slide relative to the extension handle 13, and the screw and the clamping block connected therein are used to achieve clamping and fixing. The telescopic connecting rod 82 can swing to adjust the angle to ensure that the guide roller 83 at the end is moved to the specified position, and the relative position of the abrasive sheet 5 and the carbon material is kept fixed when the abrasive tool moves as a whole.

[0034] Preferably, the outer side of the abrasive handle 1 is covered with an anti-slip layer 9 to increase the contact friction with the hand and ensure the stability of the holding operation.

[0035] In summary, the principle of this embodiment is that the built-in drive component 2 of the abrasive handle 1 provides a rotational driving torque for the grinding disc 3 and the abrasive sheet 5 at the end. When the abrasive tool is moved by manual grip or transferred by a robotic arm, the guide component 8 keeps the distance between the abrasive sheet 5 and the surface of the porous carbon material relatively fixed to prevent the carbon material from being broken during its movement.
