Novel welding roller carrier electrode mounting structure

Abstract

The invention relates to a novel welding roller carrier electrode mounting structure. The novel welding roller carrier electrode mounting structure comprises a roller carrier and a roller, the roller is rotatably mounted on the roller carrier, an insulating guide sleeve is mounted at one side of the roller and on the roller carrier, a copper electrode is sleeved with the insulating guide sleeve, and a compression spring is clamped between the copper electrode and the insulating guide sleeve. The head end of the copper electrode abuts against the flat tail end of the roller under the action of restoring force of the compression spring, a wire nose is installed at the tail of the copper electrode, and the wire nose is connected with the negative electrode of a welding power source through a cable. The novel welding roller carrier electrode mounting structure has the beneficial effects that the copper electrode electrically connected with the negative electrode of the welding power supply is directly in contact with the roller of the roller carrier, and a workpiece is directly in contact with the roller, so that the current can be well conducted.

Description

technical field [0001] The invention relates to the field of welding roller frames, in particular to an electrode installation structure of a novel welding roller frame. Background technique [0002] Welding roller frame is a common welding auxiliary equipment for welding cylindrical workpieces. Because of its simple structure and convenient operation, it is put into welding production lines in large quantities. In the process of field operation, poor welding is often caused by poor electrode contact. Generally speaking, the negative electrode of the welding power supply will be directly connected to the workpiece to be welded. Since the cylindrical workpiece needs to be rotated during welding, the welding roller frame is in the process of welding. In the process, the electrode is generally connected to the bottom frame. Due to the structural characteristics of the welding roller frame, the rolling bearing and other structures that need to be lubricated will be used, which w...

In the process of field operation, poor welding is often caused by poor electrode contact. Generally speaking, the negative electrode of the welding power supply will be directly connected to the workpiece to be welded. Since the cylindrical workpiece needs to be rotated during welding, the welding roller frame is in the process of welding. In the process, the electrodes are generally connected to the bottom frame. Due to the structural characteristics of the welding roller frame, rolling bearings and other structures that need to be lubricated will be used, which will hinder the current conduction process, resulting in welding burn-through, large welding spatter and other welding defects.
