Pipe welding jig and welding method

Abstract

The invention discloses a pipe welding jig which is used for welding of a pipe and sheet metal. The welding jig comprises a jig bottom plate and further comprises at least one set of pipe welding unit connected with the jig bottom plate. Each pipe welding unit comprises a pipe positioning mechanism which is used for positioning the pipe, a pipe rotation preventing mechanism which is used for preventing rotation during pipe welding, a sheet metal positioning mechanism which is used for positioning the sheet metal, and a sheet metal pressing mechanism which is used for tightly pressing the sheet metal. The pipe welding jig has the beneficial effects that the pipe positioning mechanism is arranged and used for positioning the pipe; the pipe rotation preventing mechanism is used for preventing rotation during pipe welding; the sheet metal positioning mechanism is used for positioning the sheet metal; the sheet metal pressing mechanism is used for tightly pressing the sheet metal; in the welding process, the pipe and the sheet metal can be positioned simultaneously, relative displacement between the pipe and the sheet metal is avoided, and the welding precision is high; and meanwhile, rotation is avoided during welding, and the welding efficiency is greatly improved.

Description

technical field [0001] The invention relates to the field of welding, in particular to a pipe fitting welding jig and a welding method. Background technique [0002] When welding pipe fittings, because the pipe fittings are easy to roll or rotate, relative displacement is likely to occur when welding with sheet metal parts, and the welding accuracy is poor. Moreover, when pipe fittings are welded, it is easy to cause reverse welding of pipe fittings or sheet metal parts, resulting in a high scrap rate. Contents of the invention [0003] In order to overcome the deficiencies of the above-mentioned prior art, the present invention provides a pipe fitting welding jig. [0004] In order to achieve the above object, the technical solution adopted by the present invention to solve the technical problems is: [0005] The pipe fitting welding jig is used for welding pipe fittings and sheet metal parts, including a jig bottom plate, and is characterized in that it also includes at...
