[0054] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0055] See also Figure 1 and Figure 2 The embodiment of the present application provides a grinding device 100, which includes a grinding component 10, a liquid supply component 20 and a linkage component 30. The grinding device 100 is used for wet grinding of workpieces.

[0056] Please also read Figure 2 , Figure 3 and Figure 4The grinding assembly 10 includes a grinding wheel 11, a liquid receiving tank 12 and a plurality of liquid receiving holes 13. The liquid receiving tank 12 is annular and is arranged on the inner side wall of the grinding wheel 11 near its axis. The plurality of liquid receiving holes 13 are evenly arranged on the tank wall of the liquid receiving tank 12. The liquid supply assembly 20 includes a liquid supply member 21 and a clamping member 22. The liquid supply member 21 is received in the liquid receiving tank 12 and is coaxially arranged with the grinding wheel 11. There is a preset liquid receiving gap 211 between the outer periphery of the liquid supply member 21 and the tank wall of the liquid receiving tank 12. The liquid supply member 21 is provided with a receiving tank 212 and a plurality of liquid outlets 213. The receiving tank 212 is used to receive liquid. The plurality of liquid outlets 213 are arranged at intervals along the circumference of the liquid supply member 21 and are all connected with the receiving tank 212. The clamping member 22 is arranged on the outer periphery of the liquid supply member 21 and is detachably connected with the grinding wheel 11. One end of the linkage assembly 30 is coaxially connected to the liquid supply member 21, and the other end of the linkage assembly 30 is connected to the external driving member. The linkage assembly 30 is used to drive the liquid supply member 21 and the grinding wheel 11 to rotate synchronously under the drive of the external driving member, so that the liquid supply member 21 provides the liquid in the receiving groove 212 to the multiple liquid receiving holes 13 through multiple liquid outlets 213 and the preset liquid receiving gap 211. Among them, the liquid received by the liquid receiving hole 13 penetrates into the outer wall of the grinding wheel 11, so that the grinding wheel 11 wet-grinds the workpiece. Exemplarily, the external driving member can be a rotating cylinder. It can be understood that the preset liquid receiving gap 211 refers to a certain spacing distance between the liquid supply member 21 and the liquid receiving groove 12, so as to avoid the outer periphery of the liquid supply member 21 directly contacting the groove wall of the liquid receiving groove 12, resulting in the inability of the liquid to be transported to the liquid receiving hole 13.

[0057] In the above-mentioned grinding device 100, the linkage assembly 30 drives the liquid supply component 21 and the grinding wheel 11 to rotate synchronously, so that the liquid supply component 21 can transport the liquid in the receiving groove 212 to the multiple liquid receiving holes 13 through the multiple liquid outlets 213 and the preset liquid receiving gap 211 under the action of centrifugal force, so that the liquid received by the liquid receiving holes 13 can evenly penetrate into the outer wall of the grinding wheel 11, so that the grinding wheel 11 can realize wet grinding of the workpiece, avoid dry friction between the grinding wheel 11 and the workpiece, and improve the grinding quality of the workpiece.

[0058] See also Figure 4 In some embodiments, the liquid supply member 21 is further provided with a liquid inlet 214, which is provided on the upper surface of the liquid supply member 21 and communicated with the receiving tank 212, and the liquid inlet 214 is used to receive liquid provided by the external liquid injection member to replenish the liquid in the receiving tank 212 to a preset volume. The liquid supply assembly 20 further includes a blocking member 23, which is provided at the liquid inlet 214 and detachably connected to the liquid supply member 21, and the blocking member 23 is used to block the liquid inlet 214.

[0059] In this way, by setting the sealing member 23 to be detachably connected to the liquid supply member 21, the sealing member 23 can seal the liquid inlet 214 after the liquid in the receiving groove 212 is replenished to a preset volume, so that the liquid in the receiving groove 212 can only be transported to the liquid receiving hole 13 through the liquid outlet 213, thereby preventing the liquid in the receiving groove 212 from flowing out from the liquid inlet 214 to other areas and wasting the liquid.

[0060] Please continue reading Figure 4 In some embodiments, the liquid supply assembly 20 further includes a liquid retaining ring 24 and a connecting member 25. The liquid retaining ring 24 is rotatably disposed in the receiving groove 212 and abuts against the groove wall of the receiving groove 212. The liquid retaining ring 24 is provided with a plurality of connecting holes 241. The plurality of connecting holes 241 respectively correspond to the plurality of liquid outlets 213 and are used to transport the liquid in the receiving groove 212 to the corresponding liquid outlets 213. One end of the connecting member 25 is connected to the liquid retaining ring 24, and the other end of the connecting member 25 is movably disposed in the groove bottom of the receiving groove 212. The connecting member 25 is used to drive the liquid retaining ring 24 to rotate, so that the plurality of connecting holes 241 are misaligned with the plurality of liquid outlets 213 and the liquid retaining ring 24 blocks the plurality of liquid outlets 213.

[0061] In this way, before replenishing the liquid in the containing tank 212, the operator drives the liquid blocking ring 24 to rotate through the connecting piece 25, so that the multiple connecting holes 241 and the multiple liquid outlets 213 are misaligned, so that the liquid blocking ring 24 blocks the liquid outlets 213, preventing the liquid from flowing out from the connected liquid outlets 213 and connecting holes 241, which is beneficial to ensure the stability of liquid replenishment.

[0062] In some embodiments, the liquid supply member 21 is further provided with a guide groove 217 , which is connected to the receiving groove 212 and receives the connecting member 25 . The guide groove 217 is used to guide the movement direction of the connecting member 25 .

[0063] In this way, by accommodating the connecting member 25 in the guide groove 217, the guide groove 217 can guide the movement direction of the connecting member 25, so that the connecting member 25 always moves along the groove track of the guide groove 217, so that the liquid blocking ring 24 can accurately block multiple liquid outlets 213, thereby improving the blocking accuracy of the liquid blocking ring 24.

[0064] It can be understood that the groove body trajectory of the guide groove 217 is an arc-shaped trajectory. When the connecting member 25 rotates to one end of the guide groove 217 and abuts against the groove wall of the guide groove 217, the multiple connecting holes 241 are respectively connected to the multiple liquid outlets 213, so that the liquid in the containing groove 212 can flow out through the connected connecting holes 241 and the liquid outlet 213; when the connecting member 25 rotates to the other end of the guide groove 217 and abuts against the groove wall of the guide groove 217, the multiple connecting holes 241 are respectively misaligned with the multiple liquid outlets 213, so that the liquid blocking ring 24 blocks the multiple liquid outlets 213.

[0065] In some embodiments, the connecting member 25 includes a connecting portion 251 and a rotating portion 252. The connecting portion 251 is movably arranged in the liquid supply member 21 and connected to the liquid retaining ring 24. The rotating portion 252 is rotatably connected to the connecting portion 251, and the rotating portion 252 is used to drive the connecting portion 251 to drive the liquid retaining ring 24 to rotate synchronously.

[0066] In this way, by setting the rotating part 252 and the connecting part 251 to be rotatably connected, when the liquid retaining ring 24 is to be rotated, the operator rotates the rotating part 252 to a vertical state, which is convenient for the operator to drive the rotating part 252 to drive the connecting part 251 and the liquid retaining ring 24 connected to the connecting part 251 to rotate synchronously. When the liquid retaining ring 24 completes the rotation operation, the operator rotates the rotating part 252 to a horizontal state to avoid interference between the rotating part 252 and other components.

[0067] See also Figure 2 and Figure 4 In some embodiments, the liquid supply part 21 includes a liquid supply portion 215 and a cover portion 216. The liquid supply portion 215 is provided with a receiving groove 212 and a liquid outlet 213 and is respectively connected to the clamping member 22 and the linkage assembly 30. The cover portion 216 is covered on the liquid supply portion 215 and is threadedly connected to the liquid supply portion 215, and the cover portion 216 is used to cover the receiving groove 212.

[0068] In this way, impurities mixed in the liquid are easy to block the liquid outlet 213 and deposit to the bottom of the receiving groove 212 to interfere with the liquid supply part 21 to provide liquid. By threading the cover part 216 and the liquid supply part 215, it is convenient for the operator to disassemble and assemble the cover part 216 and the liquid supply part 215 and remove impurities in the liquid supply part 21 in time, which is beneficial to ensure that the liquid supply part 21 stably supplies liquid to the liquid receiving hole 13, thereby improving the liquid supply stability of the liquid supply part 21.

[0069] See also Figure 4 In some embodiments, a working groove 2161 is provided on a side of the cover portion 216 away from the liquid supply portion 215 .

[0070] In this way, by setting the above-mentioned working groove 2161, a working space can be provided for the locking tool, which is convenient for the operator to insert the locking tool into the working groove 2161 and apply a driving force to the cover part 216, so that the operator can stably disassemble and assemble the cover part 216 and the liquid supply part 215.

[0071] See also Figure 24, in some embodiments, the grinding assembly 10 is further provided with a clamping groove 14, which is arranged at intervals from the liquid receiving hole 13 on the groove wall of the liquid receiving groove 12 and is adapted to the clamping member 22, and the clamping groove 14 is used to accommodate the clamping member 22, so that the grinding wheel 11 and the clamping member 22 can be detachably connected. It can be understood that there are multiple clamping grooves 14, and the multiple clamping grooves 14 are arranged at intervals along the circumference of the liquid receiving groove 12, and the number of the clamping members 22 is also multiple and is arranged one-to-one with the multiple clamping grooves 14.

[0072] In this way, by clamping the clamping member 22 in the clamping groove 14, the liquid supply member 21 can be detachably connected to the grinding wheel 11. When the liquid in the liquid supply member 21 is consumed, it is convenient for the operator to replace the liquid supply member 21 in time, and it is also convenient to replenish the liquid in the liquid supply member 21, thereby improving the working efficiency.

[0073] See also Figure 2 In some embodiments, the linkage assembly 30 includes a first spacer 31, a second spacer 32, a linkage member 33 and a locking member 34. The first spacer 31 and the second spacer 32 are respectively arranged on both sides of the grinding wheel 11 and are respectively clamped and connected with the liquid supply assembly 20. One end of the linkage member 33 abuts against the side of the first spacer 31 away from the grinding wheel 11 and is connected to the external driving member, and the other end of the linkage member 33 is penetrated through the liquid supply assembly 20 and the second spacer 32. One end of the locking member 34 abuts against the side of the second spacer 32 away from the grinding wheel 11, and the other end of the locking member 34 is penetrated through the second spacer 32 and is threadedly connected to the linkage member 33. Exemplarily, the linkage member 33 can be a flange, and the locking member 34 can be a screw.

[0074] In this way, by arranging the first material separator 31 and the second material separator 32 on both sides of the grinding wheel 11, it is prevented that the operator or other components come into contact with the grinding wheel 11 in a high-speed rotating state, thereby providing a safe working environment for the operator. In addition, by arranging the above-mentioned linkage member 33 and locking member 34, the linkage member 33 can be detachably connected to the liquid supply assembly 20 through the locking member 34, so that the grinding device 100 can be disassembled, assembled and repaired.

[0075] In some embodiments, the linkage assembly 30 further includes a first seal 35 and a second seal 36, wherein the first seal 35 is disposed between the first material separation member 31 and the liquid supply assembly 20, and the second seal 36 is disposed between the second material separation member 32 and the liquid supply assembly 20, and the first seal 35 and the second seal 36 are both in contact with the liquid supply assembly 20 and the grinding wheel 11. Exemplarily, the first seal 35 and the second seal 36 may be sealing sheets.

[0076] In this way, by setting the above-mentioned first seal 35 and second seal 36, the first seal 35 and second seal 36 can block the gap between the liquid supply component 20 and the grinding wheel 11, preventing the liquid from flowing out of the gap and making it impossible for the liquid in the supply receiving groove 212 to be completely transported to the grinding wheel 11, which is beneficial to ensure that the liquid supply component 20 stably provides liquid to the liquid receiving hole 13.

[0077] The working process of the above-mentioned grinding device 100 is roughly as follows:

[0078] First, the driving assembly drives the liquid supply member 21 and the grinding wheel 11 to rotate synchronously, so that the liquid supply member 21 can transport the liquid in the receiving groove 212 to the multiple liquid receiving holes 13 through the multiple liquid outlets 213 and the preset liquid receiving gap 211 under the action of centrifugal force, so that the liquid received by the liquid receiving holes 13 can evenly penetrate the outer wall of the grinding wheel 11, so that the grinding wheel 11 can wet-grind the workpiece, avoid dry friction between the grinding wheel 11 and the workpiece, and improve the grinding quality of the workpiece;

[0079] Then, the operator removes the liquid supply member 21 from the driving assembly and the grinding wheel 11, and drives the connecting member 25 to drive the liquid blocking ring 24 to rotate, so that the liquid blocking ring 24 blocks the multiple liquid outlets 213, and then removes the blocking member 23 and replenishes the liquid in the containing tank 212 to a preset volume;

[0080] Finally, the operator drives the connecting piece 25 to drive the liquid blocking ring 24 to return to the initial position, and connects the liquid supply piece 21 to the grinding wheel 11 through the clamping piece 22, and then assembles the liquid supply piece 21 to the driving assembly so that the grinding wheel 11 can repeat the grinding operation.

[0081] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present application and are not intended to limit it. Although the present application has been described in detail with reference to the preferred embodiments, a person of ordinary skill in the art should understand that the technical solution of the present application may be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the present application.
