Sole roughing machine with stable roughing effect

The utility model discloses a sole roughing machine with a stable roughing effect, and relates to the technical field of sole processing, the sole roughing machine with the stable roughing effect comprises an operation table and a shoe groove formed in the top of the operation table, and the height of a roughing mechanism can be adjusted according to soles with different thicknesses by arranging a first lead screw; compared with manual polishing, the shoe sole roughing machine has the advantages that the height of the roughing mechanism can be stably kept, and the effect of stable roughing is achieved. When the supporting arm moves downwards for grinding, the clamping assembly and the driving assembly form linkage, a second wedge-shaped block at the bottom end of the driving assembly is used for pushing a first wedge-shaped block to move, therefore, the two clamping blocks can move in the opposite directions to stably clamp the shoe sole, the sponge is a hard sponge material, it is guaranteed that the sponge
