When the magnesium alloy sacrificial anode rod main body 4 is positioned, one end of the magnesium alloy sacrificial anode rod main body 4 is inserted into the limiting sleeve 37, the fourth motor 40 is controlled to complete torque output to the closed driving rod, the closed driving rod is used for driving the shifting shaft sleeve 41 to complete rotation, so that the shifting shaft sleeve 41 is deduced to form bilateral displacement clamping on the magnesium alloy sacrificial anode rod main body 4, the limiting contact piece 45 is attached to the magnesium alloy sacrificial anode rod main body 4 to form clamping limiting, the swinging stress generated in the machining process is led to the third spring 44 by using the limiting contact piece 45, the elastic potential energy generated by stress compression of the third spring 44 is used for counteracting the swinging generated in the machining of the magnesium alloy sacrificial anode rod main body 4, the magnesium alloy sacrificial anode rod main body 4 is stabilized, the magnesium alloy sacrificial anode rod main body 4 is prevented from swinging and falling due to stress, and the driving gear shaft 35 is driven by the third motor 34 to complete rotation, the driving gear shaft 35 is used for driving the linkage rack column 36 to push the magnesium alloy sacrificial anode rod main body 4 to be close to the screw cap 3 under the guiding and limiting of the supporting load column 32, and the feeding before friction processing is completed.

Example two:

the processing method of the processing device of the magnesium alloy sacrificial anode rod is used for the above embodiment and comprises the following steps:

the first step is as follows: fixing the magnesium alloy sacrificial anode rod main body through an automatic clamping anti-shake falling feeding device;

secondly, the following steps: one end of the nut is clamped and fixed through a three-jaw chuck;

the third step: inserting one end of the magnesium alloy sacrificial anode rod main body into the nut by controlling the automatic clamping anti-shake falling feeding device;

the fourth step: starting a first motor to drive the three-jaw chuck, so that the three-jaw chuck can drive the nut at a high speed, and the nut and the magnesium alloy sacrificial anode rod body are rubbed to form friction welding;

the fifth step: and stably hammering the friction welding joint of the screw cap and the magnesium alloy sacrificial anode rod main body in a reciprocating manner through the auxiliary friction welding device to complete the connection of the magnesium alloy sacrificial anode rod main body and the screw cap.
