Worm processing apparatus

The utility model relates to a worm processing apparatus which belongs to a processing apparatus in the field of machine processing and is especially suitable for processing worms. The worm processing apparatus comprises a drive shaft, an adjusting apparatus and a bracket. An included angle is formed between a rotating shaft of a tool and a rotating shaft of the bracket; the bracket can drive the tool to rotate together around the rotating shaft of the bracket. Two sets of pulley structure are arranged between the bracket and a worktable. When a worm is processed, the adjustment of the worm processing apparatus is favorable for the accuracy of the shape of the teeth on the worm; the accuracy can achieve theoretically calculated value. The defects of the prior art during processing which can create sharp teeth and undercut on the surface of the teeth are avoided. The utility model has the advantages of convenient operation and high productive efficiency. The worm processing apparatus is suitable to be used on milling machine, grinding machine or common hobbing machine.
