Height can be adjusted by the rotation of leading screw 27, two mechanism's synchronization liftings can eliminate longer endoporus jet pipe 2 due to deadweight generation
Natural torsion, the deeper endoporus of part can be goed deep into and carry out sandblasting.
Before sandblasting, vehicle frame 10 is moved to the rearmost part of guide rail 101, adjusts the height of spout bracket and hoistable platform 14,
Endoporus shower nozzle 23 is made to be directed at the center of sprayed inner bore of part mouth.Vehicle frame 10 is made to move forward according to bore depth, to close to endoporus
Terminal position stops.Then allow endoporus shower nozzle 23 rotate, start sandblasting, vehicle frame 10 is displaced outwardly simultaneously, make sandblasting track be in spiral shell
Rotation shape advances to outside hole, when endoporus shower nozzle 23 exits from inner bore of part completely, that is, completes endoporus sandblasting operation.
The foregoing is only the preferred embodiment of the invention, not in order to limit the invention, all this
Within the spirit of innovation and creation and principle, any modification, equivalent substitution and improvement made etc., should be included in the invention
Protection domain within.
