Embodiment 1

[0036] like Figures 1 to 2 Shown is an embodiment of a small-diameter branch pipe welding positioning tool of the present invention, including a height adjustment assembly 1 and a stress monitoring assembly 2 arranged on the height adjustment assembly 1 for dynamically monitoring the welding stress of the small-diameter branch pipe 29, the The height adjustment assembly 1 includes a fixed base 3 and a lifting base 4 connected to the fixed base 3 for installing and adjusting the height of the small-diameter branch pipe 29; The threaded seat 6 at the central position, the threaded seat 6 is provided with a threaded hole along the vertical central axis of the threaded seat 6; the lifting seat 4 includes a first flange 7 and is erected on the first method The threaded rod 8 at the center position of the lower end of the blue plate 7 is matched with the threaded hole.

[0037]Preferably, the stress monitoring assembly 2 includes a second flange 9 and a large rectangular frame 10 ...

Embodiment 2

[0049] A positioning method for a small-diameter branch pipe welding positioning tool, comprising the following steps:

[0050] (1) Tool arrangement: according to the relative positional relationship between the small-diameter branch pipe 29 and the main pipe 28 after assembly, the welding positioning tool for positioning the small-diameter branch pipe 29 and a pair of V-shaped irons 30 for positioning the main pipe are arranged on the working platform 31, After confirming that the relative positions of the welding positioning tool and the pair of V-shaped irons 30 are accurate, the welding positioning tool and the pair of V-shaped irons 30 are respectively fixed to the working platform 31;

[0051] (2) tooling adjustment: adjust the height of the welding positioning tooling so that the center height of the inner frame of the first small rectangular frame 11 on the welding positioning tooling is consistent with the center height of the main pipe 28;

[0052] (3) Positioning of...

Abstract

The invention relates to the field of welding technology, in particular to a small-diameter branch pipe welding positioning tool and a positioning method. The welding positioning tool includes a height adjustment assembly and a stress monitoring assembly arranged on the height adjustment assembly for dynamically monitoring the welding stress of the small-diameter branch pipe. The height adjustment assembly includes a fixed seat and is connected to the fixed seat for The lifting seat for installing and adjusting the height of the small-diameter branch pipe; the fixed seat includes a bottom plate and a threaded seat integrally erected at the upper center of the bottom plate, and the threaded seat is provided with threads along the vertical central axis of the threaded seat hole; the lifting seat includes a first flange and a threaded rod erected at the center of the lower end of the first flange, and the threaded rod matches the threaded hole. The invention improves the assembly and positioning efficiency of the branch pipe and the main pipe, and improves the position accuracy of the branch pipe after welding.

Description

technical field [0001] The invention relates to the field of welding technology, in particular to a small-diameter branch pipe welding positioning tool and a positioning method. Background technique [0002] The workload of platform school management on the assembly line has been high, among which small-diameter branch pipes account for a lot. Because there is no positioning tool when carrying out branch pipe assembly, all are to rely on construction personnel to take branch pipe and carry out positioning, and take welding torch spot welding in the other hand, carry out welding after spot welding. The problems caused by this manual positioning welding operation method are: [0003] First, the assembly and positioning operation of branch pipes is labor-intensive and low in production efficiency; [0004] Second, affected by the skills of the operators, the branch pipes will be deformed after welding, resulting in poor position accuracy of the branch pipes, which will affect...
