Argon welding device for magnesium base

Abstract

The invention provides an argon welding device for a magnesium base. The argon welding device comprises a working table, a support is arranged on the working table, a guide rod is arranged on the support, guide wheels are arranged at the two ends of the guide rod, a flange fixing device is arranged on the portion, under the guide wheel on the left side, of the working table and comprises a supporting frame and a positioning rod, and the positioning rod is arranged on the supporting frame through a pressure spring; an air cylinder is arranged at the bottom end of the working table, a telescopic rod of the air cylinder is connected with the positioning rod through a steel wire, and the steel wire is guided through the guiding wheels. The positioning rod is driven by the spring to fix a flange, and the magnesium base is attached to the positioning rod to be positioned and can be welded conveniently; as an auxiliary positioning block is arranged and used for positioning the magnesium base from the side face, it is ensured that the magnesium base is placed stably, and the welding firmness of the magnesium base is improved.

Description

technical field [0001] The invention relates to the field of air-conditioning pipe manufacturing, in particular to an argon welding device for a magnesium seat used for welding a magnesium seat on a flange. Background technique [0002] When manufacturing air-conditioning pipes, it is necessary to weld magnesium seats on the flanges on the air-conditioning pipes to fix the flanges. At present, the welding of magnesium seats is usually to manually place the magnesium seats on the flanges and carry out Welding, but due to manual placement, it is easy to cause poor contact between the bottom of the magnesium seat and the flange, and the flange is easy to move, causing the magnesium seat to be skewed and affecting the welding stability of the magnesium seat. And professional welding device is then too expensive, is not suitable for the popular use of small and medium-sized enterprises. Therefore, it is particularly important to solve the problem that the magnesium seat is welde...
