Welding contact tip clamping device

Abstract

The invention provides a welding contact tip clamping device. It solves the problems of the existing guide hole of the contact tip that the welding wire is loosened due to the increase of the wire feeding wear, which causes the current to be unstable and affects the quality of the weld seam formation. The welding contact tip clamping device includes a hoop assembly and a main body. The main body is equipped with a conductive tip. The hoop assembly fixes the nose part of the contact tip. The lower part of the main body is V-shaped and has first oblique holes respectively. and the second slanted hole, the first slanted hole is equipped with a first clamping piece, the second slanted hole is equipped with a second clamping piece, the first clamping piece and the second clamping piece form a V-shaped Gripping head for holding welding wire. The invention has the advantages of being able to effectively protect the welding contact tip, avoid the influence of welding high temperature and spatter, and prevent poor contact, unstable current fluctuation, and arc welding position deviation caused by the welding contact tip due to wear, thereby ensuring welding quality.

Description

technical field [0001] The invention relates to welding equipment components, in particular to a welding contact tip clamping device. Background technique [0002] Welding contact tip is a commonly used welding equipment work piece made of conductive material with welding wire guide hole. It is generally made of conductive material copper and copper alloy. Its strength and melting point are lower than steel welding wire. There is a welding wire in the middle of the contact tip. Guide hole. During work, the welding wire will pass through the guide hole of the contact tip and enter the working surface. The current and voltage required for the ignition and combustion of the arc between the welding wire and the workpiece are transmitted through the contact tip and generated between the welding wire and the workpiece. The arc melts the welding wire. However, during the working process, due to the high temperature and spatter generated by welding, it is extremely vulnerable to da...

AI Technical Summary

Problems solved by technology

However, during the working process, due to the high temperature and spatter generated by welding, it is extremely vulnerable to damage. The diameter of the guide hole of the contact tip becomes larger due to the wear of the wire feeding, which makes the welding wire loose, resulting in unstable current, large and small, and uneven weld width. Affects the quality of weld formation

Moreover, because it is directly connected to the wire feeder head of the welding machine trolley, it is inconvenient to replace. After disassembly, the welding position is prone to deviation, which seriously affects the welding quality, and frequent replacement of the contact tip also reduces the work efficiency.
