Exhaust tail pipe welding tool

Abstract

A welding tool for an exhaust tail pipe comprises a support (1), a press block (2), an air cylinder (3) and a locating and supporting mold (4) arranged on the support (1). The locating and supporting mold (4) comprises a cavity outer mold body (4.1) and an inner support mold body (4.2), wherein the cavity outer mold body (4.1) is provided with a cavity so as to locate an outer pipe (I), and a rear cover (II) is supported by the top of the inner support mold body (4.2). The free end of a piston rod of the air cylinder (3) is connected with a press rod (5) which movably penetrates the inner support mold body (4.2) and a tail pipe body (III) upwards in sequence. The press block (2) is arranged on the press rod (5) in a sleeving manner and pressed at the top of the tail pipe body (III) so that the press block (2) can be forced to compress the top of the tail pipe body (III) to clamp and locate the whole exhaust tail pipe when the press rod (5) moves downwards. The welding tool for the exhaust tail pipe is good in locating effect, it can be effectively guaranteed that the welding positions of the outer pipe and the rear cover are precise, and welding operation is facilitated.

Description

Technical field [0001] The invention relates to the technical field of automobile exhaust tail pipe welding, in particular to an exhaust tail pipe welding tool. Background technique [0002] Such as figure 1 An automobile exhaust tail pipe is shown, which mainly includes an outer pipe I, a rear cover II and a tail pipe III which are welded and connected in sequence. When welding, generally the tail pipe and the back cover are welded and connected first, and then the back cover and the outer pipe are welded and connected. [0003] When welding and connecting the rear cover and the outer tube, manual welding is generally used, that is, the rear cover and the outer tube that are assembled together are directly welded and connected by a welding gun. The cover and the outer tube are welded without positioning tooling. The positioning effect of the outer tube and the back cover is not very satisfactory, which affects the accuracy of the welding position to a certain extent, and the unpo...

AI Technical Summary

Problems solved by technology

[0003] When welding the back cover and the outer tube, it is generally carried out by manual welding at present, that is, the back cover and the outer tube assembled together are directly welded and connected by a welding torch. The cover and the outer tube are welded without positioning tooling, the positioning effect of the outer tube and the back cover is not very ideal, which affects the accuracy of the welding position to a certain extent, and the unpositioned outer tube and the back cover are more difficult to operate during welding trouble
