The invention discloses a novel tool apron for preventing eccentric wear of a hobbing cutter. The novel tool apron comprises bases symmetrically arranged onthe two sides of the hobbing cutter, U-shaped mounting grooves opened upwards are formed in the bases, sliding guide slots are formed in the bottoms of the mounting grooves in the direction vertical to the axis direction of the hobbing cutter,fixed blocks sliding along with the sliding guide slots are mounted on the sliding guide slots, joint bearings connected witha cutter shaft of the hobbing cutter are mounted on the fixed blocks, and elastic elements are separately arranged between the mounting grooves and the fixed blocks. By adjusting the hobbing cutter and the axis angle of the hobbing cutter, eccentric wear and abrasion of thehobbing cutter are avoided, the problem that the conventional hobbing cutter is easy to wear, wear eccentrically and flake is solved, the service life of the hobbing cutter is prolonged, the replacingand maintenance numbers of times of the hobbing cutter are reduced, and the cost is saved.
