Abstract

The invention discloses a circular tube machining fixing structure. A clamping device comprises a roller, a cavity is formed in the roller, three through holes are formed in the outer round face of the roller and are evenly distributed, and a plane formed by the central lines of the three through holes is perpendicular to the axis of the roller; and a pull rod is arranged in the roller, a triangle column is arranged on the pull rod, a plane, parallel to the axis of the roller, of the triangle column is a slope, and a sliding block matched with the corresponding slope is arranged on each slope, is matched with the corresponding through hole, and penetrates the corresponding through hole. By means of the fixing structure, the working efficiency is improved, and the cost is reduced.

Description

technical field [0001] The invention relates to the field of round pipe processing equipment, in particular to a round pipe processing fixing structure. Background technique [0002] In the prior art, round pipes are often processed in various ways, such as welding flanges, drilling or cutting off, etc., so it is often necessary to fix round pipes. However, round pipes are different from ordinary workpieces and are difficult to fix and process. For example, when welding a flange, the connection between the flange and the round pipe is not firm before welding. It is usually necessary to place the flange flat on the workbench, and then place the round pipe vertically on the flange body to enhance welding. time stability. [0003] When the existing round pipe is processed, it is often due to poor fixing, which leads to disadvantages such as poor processing effect. Contents of the invention [0004] The object of the present invention is to provide a round tube processing an...
