Special-shaped die casting tapping machining device

The utility model discloses a special-shaped die casting tapping machining device which comprises a cylindrical machining table, a plurality of supporting legs are fixedly connected to the bottom of the machining table, a cylindrical machining groove is formed in the center of the machining table, and a waste hopper is fixedly connected to the bottom of the machining groove. Three hydraulic cylinders are evenly and fixedly installed on the groove wall of the machining groove, and one end of a telescopic cylinder of each hydraulic cylinder is fixedly connected with a clamping plate. Through the arrangement of the rotatable annular moving plate and the movable moving block, the position of the milling cutter can be rapidly adjusted, compared with an existing mode that the clamping position of a casting is adjusted to be matched with a cutter, the device is simpler and wider in adjusting range, meanwhile, during hole opening machining, the machining efficiency is improved, and the machining cost is reduced.
