The overall workflow of the invention is as follows:
when the grinding wheel is required to be dressed, firstly, the horizontal moving module 301 is started to drive the whole grinding wheel dressing device to horizontally move to the position right above the grinding wheel, then the vertical lifter 302 is controlled to drive the dressing device 2 to descend until the dressing device 2 is contacted with the surface of the grinding wheel, friction is carried out between the rotating grinding wheel and the dressing device 2, so that dressing of the surface of the grinding wheel is realized, the horizontal moving module 301 can drive the dressing device 2 to do horizontal reciprocating motion in the dressing process, so that the dressing device 2 can sufficiently drew the surface of the grinding wheel, and after finishing dressing, the vertical lifter 302 and the horizontal moving module 301 are reset;
In the process of trimming, synchronously, when the vertical lifter 302 drives the trimmer 2 to descend, the piston 5 is synchronously driven to move outwards in the inner cylinder 4 through the transmission mechanism 602, and in the process of moving outwards, the piston 5 sucks flushing liquid into the inner cylinder 4 on one hand and pushes the dust collector 8 to extend out of the inner cylinder 4 on the other hand; then, in the dressing process of the dresser 2, the dust collector 8 extending out of the inner cylinder 4 can intercept and collect most of dust thrown by the grinding wheel;
When the vertical lifter 302 drives the trimmer 2 to ascend, the piston 5 is synchronously driven to move inwards in the inner cylinder 4 through the transmission mechanism 602, and during the process of moving inwards the piston 5, flushing fluid is extruded into the liquid storage cavity 702 in the outer cylinder 701 through the three-way pipe 704 on one hand, and the dust collector 8 is driven to retract into the inner cylinder 4 on the other hand; when the piston 5 gradually moves to the inner end of the inner cylinder 4, the rotating mechanism drives the outer cylinder 701 to rotate, so that the first through hole 708 on the outer cylinder 701 is aligned with the second through hole 709 on the inner cylinder 4, the liquid storage cavity 702 is communicated with the inner cavity of the inner cylinder 4, and liquid in the liquid storage cavity 702 is sprayed into the inner cylinder 4, so that the dust collector 8 is washed, dust intercepted by the surface of the dust collector 8 is washed away, and the dust collector 8 can work normally in the next use.
The foregoing is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art, who is within the scope of the present invention, should make equivalent substitutions or modifications according to the technical scheme of the present invention and the inventive concept thereof, and should be covered by the scope of the present invention.
