Working procedure
Firstly, grinding wheel detection is carried out, a driving part 2 drives a grinding wheel to rotate on a measuring piece 311, the measuring piece 311 is abutted against the surface of the grinding wheel to move, a pushing piece 312 moves up and down along with the measuring piece 311, and downward pushing action is transmitted to a locking component 313;
step two, locking transmission, the locking piece 3131 pushed by the pushing piece 312 is locked after continuously moving in one direction through the mutual matching between the locking piece 31313 and the locking rack 31311, and in the process of moving the locking seat 31312, the downward moving action is transmitted to the transmission piece 3132;
step three, polishing transmission, wherein the locking piece 3131 with the largest descending position arranged along the thickness direction of the grinding wheel pushes the power support 31322 to move along with the continuous unidirectional pushing and locking of the locking piece 3131, and the locking piece 3131 is transmitted to the polishing part 4 through the rotating guide piece 31321, so that the polishing part 4 moves towards the grinding wheel, and the optimal polishing dressing distance of the polishing part 4 from the grinding wheel is adjusted to correspond to the minimum size of the detection grinding wheel in the radial direction of the locking piece 3131;
step four, grinding and maintaining, wherein the maintaining part 32 pushes the pushing support 313222 to move towards one side of the rack 1 and lock the pushing support 313222 on the rack 1, so that the optimal grinding position of the grinding part 4 is ensured to be locked and maintained;
and step five, feeding and dressing, wherein the power assembly 42 drives the grinding cutter 42 to reciprocate along the guide direction of the grinding seat 41 for grinding, and meanwhile, the feeding assembly 44 drives the grinding seat 41 to continuously feed towards the surface of the grinding wheel along the feeding track 432, so that the maximum feeding amount of the feeding track 432 can be accurately controlled to the optimal position for grinding and dressing, and after the maximum feeding amount is reached, the feeding track 432 continuously moves back to leave the grinding wheel, and the dressing action of the grinding wheel is completed.
The above description is intended to be illustrative of the preferred embodiment of the present invention and should not be taken as limiting the invention, but rather, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the invention.
