Embodiment Construction

[0033] The technical solution of the present invention is further described below in conjunction with specific embodiments:

[0034] A pipe butt welding positioning tool, such as Figure 1-9 Shown, comprise two arc-shaped half-shells 3, the two half-shells 3 have the same structure, and are provided with welding holes 17 on the side walls of the half-shells 3, so that welding rods can be inserted into the welding holes 17 for welding; One end of the housing 3 is provided with a first pin hole 15, and the other end of the half shell 3 is provided with a second pin hole 16. When the two half shells 3 are spliced ​​together, it is always the first pin hole of one half shell. The pin hole 15 is dislocated to match the second pin hole 16 of the other half shell, wherein the first pin hole 15 of one half shell is connected with the second pin hole 16 of the other half shell with the revolving pin 7, Respin 7 is made up of respin rod 20 and resell cap 21, after being connected by re...

Abstract

The invention relates to a pipe butt welding positioning tool. The pipe butt welding positioning tool comprises two movably-mounted half shells, wherein welding holes are formed in the side walls of the half shells; fastening adjusting pieces are further arranged on the side walls of the half shells; each fastening adjusting piece comprises a screw rod and a top strip; the screw rods are in threaded connection with the side walls of the half shells; and one ends of the screw rods are movably connected with the top strips. By means of the pipe butt welding positioning tool, positioning of buttwelding of two pipes can be achieved, the pipe butt welding accuracy is improved, and then the butt welding quality is improved. The positions of the top strips relative to the half shells can be changed by adjusting the fastening adjusting pieces, so that the pipe butt welding positioning tool can be wider in specification range suitable for pipes.

Description

technical field [0001] The invention relates to the technical field of shipbuilding, in particular to a pipe butt welding positioning tool and a butt welding positioning method. Background technique [0002] A large number of piping systems are involved in ship construction, many of which need to be installed on site by butt welding. During the butt welding construction, the ports of the two pipes are first aligned for positioning welding, and then the overall welding is performed. [0003] But there are following problems in prior art welding process: [0004] (1) Butt welding is performed directly based on experience, and the welding quality is difficult to guarantee; [0005] (2) Use Haval pipe clamp tooling, but different specifications of Haval pipe clamp tooling are required for pipe systems with different pipe diameters; [0006] (3) The traditional tooling is fixed by butt bolts, which is inconvenient to use. [0007] The prior art, such as the utility model paten...
