The speed reducer is controlled by a second motor, the rotation direction of the first grinding wheel is opposite to that of the second grinding wheel, the rotation speed of the second grinding wheel is smaller than the rotation speed of the first grinding wheel, and the rotation speed of the first grinding wheel is A blade for supporting the workpiece is arranged below, the cutter head part of the blade has a slope inclined downward, the blade is connected with the machine platform through a tool seat, and the bottom of the sliding frame is fixedly provided with a rack, so A driving shaft is rotatably arranged on the machine table, a gear matched with the rack is arranged at one end of the driving shaft, and an operating rod is fixedly connected to the other end of the driving shaft.

Preferably, two optical axes are arranged on the machine table, and a guide sleeve is arranged at the bottom of the sliding frame, and the guide sleeve is matched with the optical axes.

Preferably, the knife seat is provided with a vertical slot, the blade is arranged in the slot, the blade is positioned by the first locking bolt, and the knife seat is also provided with a horizontal long slot, so The tool seat and the machine table are positioned through the second locking bolt in the horizontal slot.

Preferably, the grinding wheel shaft of the first grinding wheel and the motor shaft of the first motor are driven by a belt and a pulley, and the reducer and the second motor are driven by a belt and a pulley.

The advantages and beneficial effects of the utility model are: manually place the workpiece on the blade, control the operating lever, and move the sliding frame so that the second grinding wheel moves closer to the first grinding wheel to clamp the workpiece, and then the first motor and the second motor drive The first grinding wheel and the second grinding wheel rotate to polish the workpiece, with high efficiency and good polishing effect.
