Straight pipeline inner wall weld joint welding slag grinding device

Abstract

The invention discloses a straight pipeline inner wall weld joint welding slag grinding device in the technical field of pipeline welding. The straight pipeline inner wall weld joint welding slag grinding device comprises a base, a roller driving mechanism is arranged on the right side of the top end of the base, a welding pipeline is placed at the top end of the roller driving mechanism, and a sliding groove is formed in the left side of the top end of the base. According to the straight pipeline inner wall weld joint welding slag grinding device, the purpose that a grinding rod abuts againstthe inner wall of a pipeline is achieved by pushing a sliding ring to open a sliding sleeve, the structure is stable, the grinding position is fixed, and the grinding effect of the grinding rod is good; the device can be conveniently installed in the pipeline through an arranged mechanism that a connecting ring is matched with a sliding rod, and a working rod piece can be stably supported; the position of the grinding rod can be adjusted in a limited mode through an arranged telescopic rod, a grinding rod mechanism can be conveniently installed to enter the pipeline through an arranged lead screw structure, and the polishing area can be increased; and pipelines of different weights can be driven to rotate in a limited mode through the arranged roller driving mechanism, and surrounding grinding of a weld joint is achieved.

Description

technical field [0001] The invention relates to the technical field of pipeline welding, in particular to a welding slag grinding device for the inner wall of a straight pipeline. Background technique [0002] Stainless steel pipe is a hollow long round steel, mainly used in petroleum, chemical, medical, food, light industry and other industrial pipelines and mechanical structural components. In addition, when the bending and torsional strength are the same, the weight is lighter, so it is also widely used in the manufacture of mechanical parts and engineering structures. At present, with the rapid development of industry, more and more pipes are used in all walks of life. Among them, straight seam welded pipes are widely used, but due to the natural disadvantages of welding during the processing of straight seam welded pipes, there will be burrs in the welds inside the welded pipes, which will reduce the flatness inside the welded pipes and affect daily use. In many cases...

Problems solved by technology

[0005] The object of the present invention is to provide a welding slag grinding device for the inner wall of a straight pipeline to solve the problem that although the inner line of the pipeline can be polished in the above-mentioned background technology, it is unreliable to make the grinding brush contact the inner wall of the pipeline by stretching and contracting the spring. , when grinding, the position of the grinding brush will change with the force of the spring, the grinding position is not reliable, and the grinding effect is not good. , the position of the device is supported by the grinding device, this structure is unstable, there will be a large swing when grinding, and the expansion mechanism of the device is complicated, which is not easy to manufacture
