Multi-degree of freedom grinding robot

The invention relates to a grinding robot, in particular to a multi-degree of freedom grinding robot. The multi-degree of freedom grinding robot comprises an underframe, movable mechanisms, a drivingmechanism, holding mechanisms I, a holding mechanism II, a lifting mechanism, a translation mechanism, a swing mechanism and a grinding mechanism. The movable mechanism can drive a device to move, sothat the device moves to be near a large object, and the driving mechanism drives the two holding mechanisms I two clamp the two sides of the large object. The two sides of the large object are further clamped through the holding mechanism II, the height of the translation mechanism can be adjusted through the lifting mechanism, and the translation position of the swing mechanism in the horizontalplane can be adjusted through the translation mechanism; and the swing mechanism can drive the grinding angle of the grinding mechanism to change, and the grinding mechanism carries out multi-angle grinding on the large object
