[0020] When the device is not in use, the pressure plate 6 and the table 4 are in a separated state, and the rocker arm 8 is equipped with a grinding mechanism which is once away from the table 4. When the device is in use, the circular part to be ground is placed on the upper side of the table 4, and the auxiliary positioning component makes the part centered. At this time, the first electric telescopic rod 5 is extended to make the pressure plate 6 press the part, and the second electric telescopic rod 10 controls the control rod 9 to make the grinding mechanism abut against the edge of the part. The power of the motor 14 is transmitted to the grinding mechanism through the cooperation of the first pulley 11, the second pulley 12 and the belt 13.

The push-pull rod 29 is slidably connected to the inclined grooves 31, and a control handle 32 is fixed on the side of the control disk 30.
[0025] The cooperation between the control disk 30, the inclined groove 31 and the control push-pull rod 29 enables the three limit rods 28 to move synchronously toward the center by turning the control handle 32 left and right, so that the part is concentric with the round table 4, achieving precise positioning of the part, further improving the accuracy of grinding, and at the same time making the structure and operation of the auxiliary positioning component simple, thereby improving the convenience of use of the device.
