The invention relates to an iron core ejector rod welding device, which comprises a rack, a base fixing mechanism, an ejector rod clamping mechanism, an ejection mechanism and a welding mechanism. A worktable is arranged on the rack. The ejector rod clamping mechanism consists of a clamp and a clamp seat, and is arranged on the worktable. The base fixing mechanism consisting of a base fixing seat and a through hole for containing a base is arranged above the ejector rod clamping mechanism. A spring is arranged in the base fixing seat. The welding mechanism consists of an upper electrode, a lower electrode and a cylinder, and is arranged towards the base fixing mechanism. The ejection mechanism comprises an ejection cylinder and jacking structures which are symmetrically arranged on the two sides of the ejection cylinder. The iron core ejector rod welding device additionally comprises a guide and positioning mechanism consisting of a sliding rail and a cylinder, wherein the cylinder drives a movable plate to drive the upper electrode to move up and down along a vertical direction. A pressure sensing device and a limiting device are arranged on a downward pressing path. The iron core ejector rod welding device has the advantages that not only can the labor intensity be reduced, but also the coaxiality and the welding strength between an iron core ejector rod and the base are guaranteed.
Description
technical field [0001] The invention belongs to the field of welding equipment, and relates to a welding device for an iron core ejector. Concentricity. Background technique [0002] At present, the iron core push rod used on the electromagnetic switch of the automobile starter is formed by welding and fixing a base and a push rod. The center of the base is provided with a counterbore for insertion of the ejector rod, and the ejector rod is inserted into the counterbore, and a boss is provided on the end of the insertion end. Usually, after the ejector rod is inserted into the counterbore on the base, the electrode is inserted into the counterbore by hand-held welding torch, and the boss at the end of the ejector rod is melted by electric discharge, so that the ejector rod and the base are welded and fixed. The coaxiality of the welding between the ejector rod and the center of the base is high, and the welding strength requirements are also high. If it is not met, it may ...
