摘要（英）：

The utility model relates to a welding arm lifting mechanism for a rod piece welding machine. The welding arm lifting mechanism comprises a column and is characterized in that a first speed reducer is installed at the top of the column, two chain wheels are installed on double output shafts of the first speed reducer and are matched with a chain, a first connecting block and a second connecting block are installed at the two ends of the chain, a counterweight is installed below the first connecting block, a shoulder pole is installed below the second connecting block, a pawl is installed on the shoulder pole and connected with a connecting seat, the connecting seat is connected with a guide seat, first sliding rails are installed on two sides of the column, and a first sliding block is installed on the guide seat and matched with the first sliding rails. A cross arm is horizontally arranged on the guide seat, a second sliding rail is installed on the cross arm, a second sliding block is installed on the guide seat and matched with the second sliding rail, a second speed reducer is installed on the guide seat, an output shaft of the second speed reducer is connected with a gear shaft, and the gear shaft is meshed with a rack on the cross arm. A large box beam rod piece can be welded through the welding arm lifting mechanism, and the welding arm lifting mechanism is high in efficiency and low in cost.
