Embodiment 1

[0026] like Figure 1 to Figure 5As shown, a pipe flange welding positioning tool according to the present invention includes a square base 1 arranged horizontally, the top of the base 1 is vertically rotatably connected to a column 21 through a bearing, and the top of the column 21 is vertically fixedly connected to a The pipe support plate 22, the top of the pipe support plate 22 is fixed with a pipe support assembly, the number of the pipe support assembly is 3, including a motor 31, a first lead screw 32, a slider 33 and a pipe positioning column 34. The centers of the three motors 31 are always located on the same arc, and a circular liner 35 is fixedly arranged in the space surrounded by the three motors 31, and the centers of the arc and the liner 35 are located at On the extension line of the central axis of the column 21, three sliding slots 36 are opened in the radial direction on the lining plate 35, and the included angle between two adjacent sliding slots 36 is 12...

Abstract

The invention belongs to the technical field of welding clamps, and particularly relates to a pipeline flange welding positioning tool. According to the positioning tool, motors are used for controlling first lead screws synchronously so as to further control the position adjusting of three vertical pipeline positioning columns, so that the tool can adapt to positioning of pipelines with differentdiameters, the center of a flange is adjusted to be overlapped with a central axis of each pipeline positioning column through a flange center adjusting assembly, the flange is placed at the top endof a pipeline through a second lead screw, and the good vertical alignment of the flange and the pipeline is realized; compared with the prior art, the positioning tool can meet the positioning of more pipeline flanges with different sizes, and the use number of the positioning tool is reduced; the flange and the pipeline which are aligned primarily are subjected to three-point fixation by spot welding, then a flange bearing plate is moved away by rotating the second lead screw, a pipeline bearing plate is rotated horizontally to carry out one-circle welding at a joint, a welding device does not need to move in the welding process, the operation is convenient, and time and labor are saved.

Description

technical field [0001] The invention belongs to the technical field of welding fixtures, in particular to a pipeline flange welding positioning tool. Background technique [0002] During the welding process of pipeline flanges, the flange and the pipeline need to be perpendicular to each other, and the central axis of the pipeline needs to be consistent with the center of the flange. If there is no auxiliary device during welding, it is difficult to achieve true alignment. Traditional auxiliary devices generally only Auxiliary fixing of pipe flanges of several sizes can be provided, so when there are more pipe flanges, the number of positioning devices required will also increase, which is costly and inconvenient to use. [0003] China's published patent "A Pipeline Flange Welding Positioning Tool" (publication number: CN205967913U) discloses a positioning device that can satisfy several sets of pipe flanges at the same time. However, each such device can provide Although t...
