Steel pipe polishing robot

Abstract

The invention relates to the field of steel pipe production, in particular to a steel pipe polishing robot. The polishing robot comprises an operation table, a protective cover, a fixing mechanism, apolishing mechanism, a cleaning mechanism and a pushing mechanism. The fixing mechanism is fixed to the operation table, the pushing mechanism is fixed to the protective cover, through cooperative useof the fixing mechanism and the pushing mechanism, a steel pipe is convenient to move, rust removal and polishing are conveniently conducted on all positions of the steel pipe, dirt remaining on thesteel pipe on the fixing mechanism is cleaned through the pushing mechanism, and continuous use of the fixing mechanism is facilitated. The polishing mechanism is fixed to the protective cover, polishing stones in the polishing mechanism are annularly distributed, and therefore when the polishing stones are used for derusting and polishing the steel pipe, the polishing stones can evenly extrude and polish the side wall of the steel pipe, the side wall of the steel pipe can be kept smooth, and the thickness of the pipe wall of the steel pipe cannot be changed.

Description

technical field [0001] The invention relates to the field of steel pipe production, in particular to a steel pipe grinding robot. Background technique [0002] Steel pipe, a hollow cylindrical steel. Steel with a hollow section whose length is much greater than its diameter or circumference. According to the cross-sectional shape, it can be divided into circular, square, rectangular and special-shaped steel pipes; according to the material, it can be divided into carbon structural steel pipes, low alloy structural steel pipes, alloy steel pipes and composite steel pipes; Steel pipes for thermal equipment, petrochemical industry, machinery manufacturing, geological drilling, high-pressure equipment, etc.; according to the production process, they are divided into seamless steel pipes and welded steel pipes, among which seamless steel pipes are divided into hot-rolled and cold-rolled (drawn) Two kinds, welded steel pipe is divided into straight seam welded steel pipe and spi...

Problems solved by technology

[0003] However, when the steel pipe is preserved, due to improper preservation, the surface of the steel pipe will be rusted, so it is necessary to remove the rust on the surface of the steel pipe before use, so as to facilitate the use of the steel pipe; When removing rust, due to the long length of the steel pipe, the steel pipe cannot be moved after the steel pipe is fixed, and the place where the steel pipe is fixed cannot be polished to remove rust; when the steel pipe is polished, generally a disc-shaped The grinding wheel derusts the surface of the steel pipe, but due to the circular structure on the surface of the steel pipe, when the arc-shaped surface of the steel pipe is used for grinding with the grinding wheel, the surface of the steel pipe will be deformed, the wall thickness of the steel pipe surface will be changed, and the impact will be affected. The use of steel pipes
