Embodiment 2

[0029] Embodiment 2 of the pipe joint welding jig of the present invention differs from Embodiment 1 in that: in Embodiment 1, the stop structure between the second positioning rod and the second pipe joint is an outer shoulder. In this embodiment, the stop The structure can also be a boss arranged on the outer peripheral surface of the second positioning rod.

Embodiment 3

[0030] Embodiment 3 of the pipe joint welding jig of the present invention differs from Embodiment 1 in that: in Embodiment 1, the connection hole and the plug joint are connected by threads. In this embodiment, the thread on the connection hole and the plug joint can also be omitted. , the plug joint is guided and assembled in the connection hole, and the operator can push the second positioning rod to move axially to connect with the connection hole when in use.

[0031] Embodiment 4 of the pipe joint welding jig of the present invention differs from Embodiment 1 in that in Embodiment 1, the first positioning rod and the second positioning rod are detachably connected through the connection hole. In this embodiment, the first positioning rod U-shaped card slot or cross-shaped card slot can also be set at the first extending end of the second positioning rod. When pushing the second positioning rod, the plug connector of the second positioning rod is inserted into the slot of...

Abstract

The invention relates to a welding fixture for pipe joints. The welding fixture for the pipe joints comprises a first positioning rod and a second positioning rod; the first positioning rod allows thefirst pipe joint to be sleeved and is positioned in the radial direction, and the second positioning rod allows the second pipe joint to be sleeved and is positioned in the radial direction; the first positioning rod and the second positioning rod are provided with a corresponding first extending end and second extending end for penetrating into a transition joint correspondingly; and the first extending end and the second extending end are provided with mutually-matched and detachable positioning structures. The first pipe joint and the second pipe joint are positioned through the first positioning rod and the second positioning rod correspondingly, so that the first pipe joint and the second pipe joint are coaxial with the first positioning rod and the second positioning rod correspondingly, meanwhile, the first extending end of the first positioning rod is detachably connected with the second extending end of the second positioning rod, thus the second positioning rod and the firstpositioning rod keep the fixed positions, the first pipe joint and the second pipe joint are accurately positioned, the welding difficulty of the pipe joints is reduced, the welding efficiency of thepipe joints is improved, and the welding quality of the pipe joints is guaranteed.

Description

technical field [0001] The invention relates to a pipe joint welding jig. Background technique [0002] Joints are commonly used mechanical parts in daily life. Existing right-angle pipe joints of metal materials usually include a first pipe joint with a transition joint and a second pipe joint connected to the first pipe joint through a transition joint. The transition joint has The welding hole is used for welding with the second pipe joint, and the transition joint of the first pipe joint is connected with the second pipe joint through welding. [0003] In the prior art, the first pipe joint and the second pipe joint are usually welded by manual observation and positioning. However, during the welding process, the right-angle pipe joint is difficult to support manually, and the second pipe joint covers the welding hole of the transition joint. The operator cannot determine the coaxiality between the welding hole of the transition joint and the second pipe joint, which ma...
