Automatic gas shielded welding machine

Abstract

The invention discloses an automatic gas shielded welding machine which comprises a machine tool, a vibration screening disc and a welding frame are arranged on the machine tool, a workpiece clamp, a carbon dioxide wire feeding welding head and a pushing mechanism are arranged on the welding frame, a discharging sliding way is arranged on the vibration screening disc, and the discharging sliding way is in butt joint with the workpiece clamp. Workpieces to be welded enter the workpiece clamp along the discharging sliding way in a queuing mode, the carbon dioxide wire feeding welding head is located on one side of the workpiece clamp, when the carbon dioxide wire feeding welding head gets close to and makes contact with the workpieces, welding is completed, and the pushing mechanism acts on the workpiece clamp to push out the welded workpieces for discharging. According to the automatic gas shielded welding machine, a series of actions of automatic feeding, welding and discharging of parts are achieved, a proper workpiece clamp is selected for specific part shapes, the equipment structure is simple, the cost is low, the welding quality is good, and the machining efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of automatic welding machines, in particular to an automatic gas shielded welding machine. Background technique [0002] Carbon dioxide gas shielded welding is a metal arc welding method in which carbon dioxide is used as a protective gas. When working, a gas protective layer is formed around the arc to isolate external oxygen, so that the weld will not be oxidized and carbonized, thereby improving the quality of the weld and making the welding plane more Beautiful and smooth, the carbon dioxide gas shielded welding machine can make the production efficiency several times higher than manual arc welding, save electricity significantly, and produce low cost. [0003] In the welding conditions of small and medium parts, the gas shielded welding machine used is often a manual operation tool. During the welding process, due to factors such as the technical level and physical condition of the operator, there are m...

AI Technical Summary

Problems solved by technology

[0003] In the welding conditions of small and medium parts, the gas shielded welding machine used is often a manual operation tool. During the welding process, due to factors such as the technical level and physical condition of the operator, there are many interference sources, which are prone to poor joints and weld seams. Welding defects such as unattractive shape, deviation of weld straightness, etc., relying on the welder's hand-held welding torch for welding has high strength and low welding efficiency, and there are many joints on one weld

However, the general-purpose gas shielded welding equipment has high cost and large volume, which increases the processing cost.
