Specific implementation mode
For a clearer understanding of the technical features, objectives and effects of the utility model, existing control description of the drawings
Specific embodiment of the present utility model.
Structure is protected in a kind of sandblasting of the utility model and the hole of anodic process, for mounted on the hole of surface workpieces processing
In, prevent surrounding environment solution or sand grains access aperture in destroy pore structure；In its preferred embodiment, institute is please referred to Fig.1
Show, the hole protection structure of the sandblasting and anodic process includes plunger 1, and 1 side of the plunger is equipped with annular recess 3, the ring
Sealing ring 4 is installed, the sealing ring 4 protrudes 1 side surface of the plunger in shape groove 3；The plunger 1 is inserted in the hole
In, the sealing ring 4 and the madial wall in the hole are interference fitted.The utility model as described above is in order to avoid needing to process
The hole of workpiece influenced by solution or sand grains, destroy the quality of internal surface of hole, realized in device to hole by " soft " cooperation
The plug that is hermetically sealed and ensureing plunger 1 in portion not defective work piece hole surface structure.It can be with hole table by being arranged on plunger 1
The flexible sealing ring 4 of interference fit is realized in face, is realized the sealing effect on sky surface and plunger 1, will not be leaked, simultaneously
The plug process for also simplifying plunger 1 avoids the damage of " hard " cooperation device to hole.
