[0040] Working principle

[0041] When the tool head grinding device starts to work, the servo motor two 41 in the power mechanism 4 starts to work, and the output end of the servo motor two 41 drives the transmission wheel 42 connected thereto to rotate, and through the transmission of the transmission belt 43, power is transmitted to the transmission wheel 42 at the other end of the rotating rod 32, thereby driving the rotating rod 32 to rotate. Since the polishing wheel 33 is sleeved on the rotating rod 32 and fixed by the locking piece 34, the rotation of the rotating rod 32 causes the polishing wheel 33 to rotate, and the grinding operation on the tool head begins.

[0042] When it is necessary to clean or replace the polishing piece 3, the transverse moving mechanism 1 starts to work, and the servo motor one 15 starts to work, and the output end of the servo motor one 15 drives the adjusting screw 13 to rotate. Since the transverse block 14 is threadedly sleeved on the outer wall of the adjusting screw 13, and the transverse block 14 is connected with the bottom of the support frame 2, according to the screw transmission principle, the rotation of the adjusting screw 13 will make the transverse block 14 move linearly along the adjusting screw 13.

[0043] The movement of the transverse block 14 drives the support frame 2, the polishing piece 3, the power mechanism 4 and the tension adjusting piece 5 mounted thereon to move together, so that the polishing piece 3 leaves the polishing position, and the operator can clean or replace the polishing piece 3. When the device is debugged, maintained or needs to be separated from the power mechanism 4 and the polishing piece 3, the tension adjusting piece 5 needs to be used to adjust the tension of the transmission belt 43. After the transmission belt 43 is loosened, the operator can separate the power mechanism 4 from the polishing piece 3 and maintain the polishing piece 3.

[0044] Although the embodiments of the present application have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and modifications can be made to these embodiments without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
