Abstract

The invention relates to a safety protection device for a special iron core ejector rod welding machine. The safety protection device comprises a safety light curtain and two light curtain supports. The two light curtain supports are symmetrically arranged on the two sides of the front of the worktable of the rack of the welding machine. The safety light curtain consists of a light transmitter and a light receiver, wherein the light transmitter and the light receiver are arranged on the light curtain supports and face each other. The safety light curtain is connected with the welding head of the welding machine. The light transmitter comprises an elongated plate body and a plurality of infrared transmitters. The light receiver comprises an elongated plate body and a plurality of infrared receivers. By arranging the safety light curtain on the two sides of the rack of the welding machine, when an operator stretches a hand into a movement area, the safety light curtain can automatically sense the hand, the welding head goes back to the original position, the safety performance is improved, and the safety of the operator and equipment is fully protected.

Description

technical field [0001] The invention belongs to the field of welding equipment and relates to a safety protection device for a special welding machine for iron core push rods. Background technique [0002] At present, the moving 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 hi...
