Machining treatment equipment for mechanical parts

The invention belongs to the field of machining, and particularly relates to mechanical part machining treatment equipment which comprises a workbench and a support, a containing groove used for containing parts is formed in the workbench, a surrounding plate is installed on the inner bottom wall of the containing groove, an air spraying opening is formed in the inner wall of the surrounding plate, and a plurality of inflators are installed on the support. A piston piece is arranged in the inflator, and a plurality of movable rods are movably connected to the outwards-extending plate in an inserted mode and connected with the piston piece. In the part machining process, the machining device can drive the workbench to generate rapid vibration, then the movable rod is driven to continuously shake up and down, the movable rod drives the piston piece to move, the piston piece conducts inflating work in the inflator, generated air flow is sprayed out towards the interior of the surrounding plate through the air sp
