Problems solved by technology
The traditional sandblasting machine mostly uses a single plane feed for the fixture or nozzle. When the single plane feed is used for sandblasting the curved shell parts with complex shapes, the surface of the curved shell parts will be unevenly blasted, and the sandblasting is uneven. In place, resulting in problems such as surface deformation of curved shell parts

The invention discloses a precise numerical control sand blasting machine for curved-surface shell parts. The precise numerical control sand blasting machine comprises a sand blasting device located at the upper portion, a clamping adjustment device which is located at the lower portion and used for the curved-surface shell parts and a computer control system; the sand blasting device is composedof a driving displacement mechanism and a spraying gun assembly; the sand blasting device comprises a double-arm supporting frame, a lateral guide rail, a longitudinal guide rail, a first sliding block and a second sliding block; the clamping adjustment device comprises a flexible clamp, a pan / tilt, a worktable and a guide rail; the computer control system adopts numerical control programming software for inputting a three-dimensional numerical model of the sand blasting machine according to the process requirements of the curved-surface shell parts, and a numerical control program outputs rotation and movement trajectories of nozzles and the curved-surface shell parts. The precise numerical control sand blasting machine can complete sand blasting treatment on various curved-surface shellparts with complex shapes by changing the position of the flexible clamp.
Description
technical field [0001] The invention relates to the field of precision manufacturing, in particular to a multi-directional, freely adjustable box-type numerical control sand blasting machine. Background technique [0002] Sandblasting is widely used in industrial production and manufacturing, especially in the precision manufacturing industry, where sandblasting plays an important role in the service life and surface roughness of parts. When sandblasting curved shell parts with complex shapes, it is usually done by manual sandblasting, and manual sandblasting depends on the production experience of workers and also affects the health of workers. The traditional sandblasting machine mostly uses a single plane feed for the fixture or nozzle. When the single plane feed is used for sandblasting the curved shell parts with complex shapes, the surface of the curved shell parts will be unevenly blasted, and the sandblasting is uneven. In place, resulting in problems such as surfac...
