Abstract
This utility model relates to a milling cutter head for hydraulic valve bodies, comprising a base disc, a fixed cutter holder, a movable cutter holder, and a cutting tool. The movable cutter holder is connected to a first inclined block via a guide block, and the first inclined block is linked to a ball screw mechanism. The ball screw consists of a fixed shaft, a rotating shaft with worm gear helical teeth, and a screw shaft, which meshes with a sliding nut on the first inclined block. An adjusting bolt is provided at the bottom of the base disc, which drives the worm gear helical teeth to rotate via a connecting rod gear, thereby rotating the screw shaft and causing the first inclined block to move radially, thus precisely adjusting the cutting radius of the cutting tool on the movable cutter holder. After adjustment, tightening the locking bolt pushes the second inclined block to press against the disc spring structure to lock the adjusting bolt.
