Automatic welding rod replacing device for rotor spot welding machine

Abstract

The invention provides an automatic welding rod replacing device for a rotor spot welding machine. The automatic welding rod replacing device comprises a new welding rod storage clamp, a welding rod push rod mechanism, a used welding rod receiving device, a welding rod positioning device, a welding rod clamping seat and a tightening device. The new welding rod storage clamp is used for storing standby welding rods; the welding rod push rod mechanism is used for pushing welding rods to a welding required position; the used welding rod receiving device is used for collecting incompletely used welding rods; the welding rod positioning device is used for positioning welding rods; the welding rod clamping seat is used for clamping the welding rods during welding to prevent the welding rods from slipping; the tightening device is used for tightening or loosening a fixing device on the welding rod clamping seat. By the automatic welding rod replacing device, the problems of demounting of the used welding rods, storage and discharging of new welding rods, positioning and clamping of the new welding rods, spot welding count setting and automatic control of the whole process are solved, automatic replacing and clamping of the welding rods can be realized without manual intervention, automation degree is greatly improved, labor intensity is relieved, uniformity in clamping of the welding rods can be guaranteed, and production efficiency is improved.
