[0035] Working principle: On the rotating table 6, the motor rotor positioning cylinder 9 is used to place the rotor 10, and the motor outer frame base 8 is used to place the motor housing 11. Before the shaft is inserted, it is necessary to push the fixing seat 42 downward on the electric push rod 3 41 so that the top of the rotor 10 is embedded in the rotor positioning hole 47, and then push the piston 46 to move by inflating the air chamber 43, thereby driving the clamping claw 45 to approach the rotor 10, so as to realize the vertical clamping of the rotor 10.
