Abstract
An underwater inner wall grinding device relates to the field of grinding. The underwater inner wall grinding device solves the problem of production machining inconvenience caused by the fact that the grinding effect is poor, and grinding is not conducted in place. The underwater inner wall grinding device comprises an inverted right-angle triangular water tank, a grinding block and a grinding block rotating frame. The grinding block rotating frame comprises an outer rotating shaft, a telescopic support and a movable rod. The telescopic support is 8-shaped. The grinding block is fixed on a column pin on the axis of a non movable rod. A sliding groove for the telescopic support to slide leftwards and rightwards is formed in the side of the outer rotating shaft, and the movable rod stretches out of the outer rotating shaft leftwards to be connected with the cylinder. The underwater inner wall grinding device is simple in structure, convenient to operate, good in grinding effect and free of dead corner. The telescopic support is variable in amplitude and capable of grinding workpieces with different inner diameters. Heat generated during grinding is carried away by water, air is isolated by the water, oxidation caused by grinding is reduced, and the grinding quality is improved.
