Welding device for special-shaped bent pipe

Abstract

The invention discloses a welding device for a special-shaped bent pipe. The special-shaped bent pipe is installed on a working platform. The special-shaped bent pipe comprises a plurality of horizontal sections and a plurality of oblique sections. The horizontal sections are parallel to the working platform. An included angle is formed between each oblique section and the working platform. The welding device for the special-shaped bent pipe comprises at least one first supporting mechanism used for supporting the horizontal sections, at least one second supporting mechanism for supporting the oblique sections, a limiting mechanism used for limiting the movable end of the special-shaped bent pipe, at least one first clamping mechanism for clamping the special-shaped bent pipe, and a second clamping mechanism for clamping the middle portion of the special-shaped bent pipe. The welding device is simple in structure, the special-shaped bent pipe is clamped and positioned, looseness and displacement are not likely to happen, the welding precision of the special-shaped bent pipe is effectively guaranteed, welding application of a welding machine is facilitated, the welding and assembling efficiency is improved, welding errors are reduced, and the welding quality of products is improved.

Description

technical field [0001] The invention relates to an auxiliary equipment for auto parts welding, in particular to a welding device for special-shaped bent pipes. Background technique [0002] The shape of the special-shaped elbow in auto parts is indeterminate, and the welding is generally carried out by manual welding, that is, the welding torch is used to directly weld the assembled pipe fittings. When welding, the assembled pipe fittings are directly welded. Welding, without positioning tooling, the positioning effect of the special-shaped elbow is not very ideal, which affects the accuracy of the welding position to a certain extent, resulting in errors, thus affecting the welding quality of the product, and the unpositioned pipe fittings are more difficult to operate when welding. trouble. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the above-mentioned prior art and provide a welding device for special-shap...
