Pipeline rapid welding auxiliary device

Abstract

The invention discloses a pipeline rapid welding auxiliary device. The device comprises a supporting assembly, polish rods installed on the supporting assembly, two positioning assemblies and a supporting piece, wherein the positioning assemblies and the supporting piece are connected to the polish rod in a sliding and sleeving mode, and the supporting piece is located between the two positioningassemblies; each positioning assembly comprises a motor and a limiting piece connected with the output end of the motor; and the to-be-welded butt joint ends of two to-be-welded pipelines abut againsteach other and are in lap joint with the supporting piece, the opposite ends of the two pipelines are inserted into the limiting pieces at the respective ends, and the motors can drive the two to-be-welded pipelines to rotate synchronously for welding. By means of the device adopting the design, rapid butt joint of the to-be-welded pipelines can be achieved, and the pipelines can synchronously rotate in the same direction while coaxiality of the pipelines is guaranteed; and rapid clamping and positioning of various pipelines with different diameters can be achieved, and the production efficiency is improved.

Description

technical field [0001] The invention belongs to the field of welding technology, and in particular relates to a quick welding auxiliary device for pipelines. Background technique [0002] Pipe welding technology is a commonly used technology in industrial production. In actual pipe welding process, it is easy to cause excessive deviation of coaxiality and affect the quality of subsequent products. It needs precise positioning tooling to complete. The production of water purifiers will involve the welding of stainless steel pipes. However, they are all welded manually by welders. This kind of production speed is very slow and the welding quality is not high. There are often large deviations in the concentricity of welded pipes. Contents of the invention [0003] The object of the present invention is to provide an auxiliary device for rapid welding of pipelines to solve the problems in the background technology. [0004] In order to achieve the above purpose, the specific ...
