In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a special mechanism of whetting a knife of numerical control cutter, includes base and sharpedge grinding machine body, sharpedge grinding machine body both sides all are provided with balancing unit, balancing unit includes solid fixed ring, and gu fixed ring's outer wall has seted up the ring channel, gu fixed ring is close to the lateral wall of ring channel and has seted up the groove of stepping down, the inside balancing weight that is provided with of ring channel, and the upper surface of balancing weight set up threaded hole, threaded hole inside is provided with supporting screw, gu fixed ring keeps away from one side of ring channel and is provided with a plurality of balancing weight rings.
Preferably, the section of the annular groove is trapezoidal, and the balancing weight is frustum-shaped.
Preferably, a plurality of the counterweight rings are provided with a backing plate on the side wall far away from the fixing ring, and the backing plate is made of rubber.
Preferably, the counterweight ring is made of cast iron.
Preferably, the lower surface of the base is fixedly connected with a ground anchor.
Compared with the prior art, the beneficial effects of the utility model are that:
1. the utility model has the advantages that by arranging the counterweight ring, the grinding wheel on one side of the knife sharpener body is used less, so that the grinding wheel on one side of the knife sharpener body becomes lighter, the quality of the grinding wheel is balanced by increasing or decreasing the counterweight, and the dynamic balance of the grinding wheel is adjusted by the counterweight, so that the vibration of the knife sharpener is reduced, the difficulty of sharpening is reduced, and the service life of the knife sharpener is prolonged;
2. the utility model discloses, be trapezoidal ring channel and balancing weight cooperation through setting up the section, the dynamic balance's of being convenient for regulation through setting up the backing plate, avoids the direct emery wheel that collides with the emery wheel contact of counter weight ring, and through the counter weight ring that sets up cast iron material, increases the life of counter weight ring, through setting up the earth anchor, increases the fixed of sharpedge grinding machine body and ground to reduce the vibrations of sharpedge grinding machine body.
