The device's grinding base 1 can realize the rotation and the horizontal linear motion of grinding machanism 2, can make grinding wheel 29 be close the part of polishing with different angles and polish, drives angle adjustment wheel 53 and rotates the inclination that can finely tune the part of treating to polish simultaneously at the in-process of polishing. When the belt 24 of the grinding mechanism 2 is loosened, the motor mounting plate 26 can be rotated upwards by driving the adjusting hydraulic cylinder 27, so that the belt 24 is tensioned again, and the designed limiting groove 2711 is matched with the limiting block 272, so that the position stability of the adjusted motor 25 can be ensured. Because the distance between the belt pulleys of the belt is adjusted in a rotating mode, the belt 24 can be tensioned again by rotating a larger angle along with the increase of the rotating angle, so that the distance between the limiting grooves 2711 is gradually increased from top to bottom, and the increase of the distance between the belt pulleys at each time is ensured not to have larger deviation. First anti-slip groove 2611 and second anti-slip groove 2622 may prevent sliding support block 262 from wobbling after the pulley spacing has been adjusted.

The beneficial effects are as follows:

the grinding base 1, the feeding mechanism 3 and the servo lifting mechanism 4 designed by the device are matched, so that the grinding wheel 29 can be ground at different angles and directions.

The grinding mechanism 2 that the device designed adjusts the interval between the belt pulley through the pivoted mode, and the design has spacing groove 2711 that the interval is different on the telescopic link 271 of adjusting, error when can effectual reduction adjust the belt pulley interval at every turn. The first anti-slip groove 2611 and the second anti-slip groove 2622 have different angles, so that the motor 25 can be prevented from shaking caused by the shaking of the sliding support block 262 during the operation of the device.

The fixing mechanism 5 that the device designed is fixed through electro-magnet 531 and is treated the part of polishing, compares with traditional fixing mechanism, and the fixed box of being convenient for polishes the part of various shapes, reduces the influence that fixing mechanism caused the process of polishing, and can drive angle adjustment wheel 53 and rotate in the process of polishing, and the inclination of treating the part of polishing is finely tuned, improves the effect of polishing.
