APPARATUS FOR POLISHING INNER SURFACE OF GAS BARREL

摘要

The present invention relates to an apparatus for polishing an inner surface of a gas container, capable of safely and conveniently installing a gas container at a rotation center for barrel polishing, as well as transporting and moving the gas container, cleanly polishing even upper and lower portions of an inner surface of the gas container through a tilting function, and easily installing a gas container having a different size according to a gas storage amount to fit the rotation center. The apparatus for polishing an inner surface of a gas container comprises: a main frame installed to be fixed to a bottom surface; a rotary frame installed to rotate by 90 degrees such that an upper surface thereof faces a front or upper side of the main frame; a rotationally driving unit rotatably driving the rotary frame with respect to the main frame; a tilting frame installed to be rotatable forwards and backwards on an upper portion of the rotary frame; a tilting driving unit tilting-driving the tilting frame with respect to the rotary frame; and a container installation and rotating unit installed in an upper portion of the tilting frame, allowing the gas container with an abrasive injected therein to be rotatably installed therein, and rotating the gas container in a longitudinal direction of the gas container as a rotation center.
