The beneficial effects of the utility model are：
First, a kind of towed flexible polishing column for steel tube inner hole of the utility model, due to cylindrical rubber item
The elasticity of flexible and elastic polished circle, thus even if steel pipe has the curvature of certain angle, can also realize the high-quality of steel tube inner hole
Amount polishing.
Second, a kind of towed flexible polishing column for steel tube inner hole of the utility model, in cylindrical rubber during work
A certain amount of compressed air is filled in air source through-hole so that cylindrical rubber item is radially expanded, so as to which the polishing for obtaining required is squeezed
Pressure is conducive to improve quality of finish；In addition compressed air to rise outside cylindrical rubber item, can compensate for the mill of elastic polished circle
Damage is conducive to improve the service life of elastic polished circle.
Third, a kind of towed flexible polishing column for steel tube inner hole of the utility model, liquid polishing agent are closed
Between steel pipe and flexible polishing column and form certain hydraulic coupling so that polishing agent can uniformly and stably enter elastic polished circle
Between steel tube inner hole, the surface quality of polishing is good.
