[0002] An industrial robot is a mechatronic automated production device that simulates the functions of a human arm and wrist. As more and more industrial robots enter the production workshop, the maintenance of industrial robots is a key task to ensure the normal operation of the robots. The installation and adjustment of the industrial robot spindle have become difficult pain points. The main manifestations are as follows: The industrial robot spindle bears a large radial load, and the tolerance precision of the fit between the spindle and the hole is high. After being used for a period of time, the load journal of the spindle wears or eccentric crankshaft steps appear, and the tolerance of the fit between the spindle and the main body hole of the industrial robot decreases. It is necessary to install and adjust the spindle. When using traditional maintenance tools (using a small hammer and a pin puller) to install and adjust the spindle, the spindle is installed and adjusted by impact force, which has a high risk factor, difficult operation, uncontrollable maintenance quality, and even irreversible damage to the main body hole of the industrial robot and the load connection end, and even the risk of scrapping the industrial robot main body and the load end.
