Abstract

The invention discloses a grinding device for the inner wall and the outer wall of the pipe opening of a steel pipe. The grinding device comprises a base, steel pipe supports fixed to the base and used for supporting and rotating the steel pipe, a grinding assembly and a rotating assembly, wherein the grinding assembly and the rotating assembly are arranged on one side of the steel pipe supports. The grinding assembly comprises a machine frame, a drive device arranged in the machine frame, a transmission mechanism arranged in the machine frame, and two grinding wheels arranged on the outer side wall of the machine frame and driven by the drive device and the transmission mechanism to rotate. The rotating assembly extends into the machine frame. The whole machine frame is driven by the drive device to rotate. The two grinding wheels are fed to the steel pipe placed on the steel pipe supports to grind the pipe opening of the steel pipe. The two grinding wheels are arranged, and therefore the inner wall and the outer wall of the steel pipe can be ground at the same time, and the work efficiency is greatly improved; and in addition, the rotating assembly is arranged, and therefore the two grinding wheels can make contact with the inner wall and the outer wall of the steel pipe at the same time, and the grinding quality can be ensured.

Description

Technical field [0001] The present invention is the field of equipment manufacturing, and it is specifically a steel pipe port polishing device. Background technique [0002] Nowadays, the pre -welding industry of petroleum pipelines mostly use automated welding. According to the pipe welding process, in order to make the welding interface better, the iron oxide, dirt, and dander of the steel pipe port must be cleaned.Welding is performed, so the inside and outside walls of the tube need to be polished. [0003] At present, the polishing machine on the market is mainly polished outside or inner wall, which is difficult to improve the efficiency of integrated work.In order to reduce labor intensity, improve work efficiency, and target the current market gaps, it is necessary to develop a automatic pipe port polishing machine to achieve the inner and outer wall at the same time and improve efficiency. Invention content [0004] The purpose of invention: The purpose of the present ...
