High-efficiency automatic welding device for pin shaft sleeve

The invention belongs to the technical field of welding devices, particularly relates to a high-efficiency automatic welding device for a pin shaft sleeve. The following scheme aiming at the problems that an existing pin shaft sleeve is generally welded manually, so that the skill levels of welders are different, the quality of welding beads is different, the welding efficiency is low and the welding effect is not ideal is provided. The high-efficiency automatic welding device for the pin shaft sleeve comprises a machining table, a fixing plate is fixedly mounted at the top of the machining table, a driving motor is fixedly mounted on one side of the fixing plate, a rotating rod is fixedly mounted on an output shaft of the driving motor, a sliding groove is formed in the top of the machining table, a threaded seat is slidably mounted in the sliding groove, the top of the threaded seat extends to the outer side of the machining table and is fixedly provided with a sliding plate, and a rotating shaft is rotatio
