Problems solved by technology

Machine hoisting of motor rotor components is not possible due to space limitations of the hydraulic press
And because the self-weight of the motor rotor is relatively large, it will cause a large manpower consumption during the press-fitting process of the motor rotor.
Stacking the components on the operating table of the hydraulic press before press-fitting, and manually adjusting the positioning accuracy may also easily lead to insufficient positioning accuracy, which may cause damage to the motor rotor parts during the press-fitting process, so that failures and failures may occur during the later use of the motor. Problems such as high scrap rate

Description

Technical field [0001] The present invention involves the field of motor workmade technology, and specially involves a motor rotor pressure worker. Background technique [0002] Electric rotor pressure is an important step in the process of motor production assembly.The traditional pressure method is to place the motor rotor to the operating countertop of the hydraulic press and adjust the positioning of the hydraulic press, and then use the hydraulic pressure department to run the rotor of the rotor through all components of the rotor of the rotor.Due to the space limitations of the hydraulic press, the machine crane for the motor rotor component cannot be achieved.Because the self -weight of the motor rotor is large, it will cause greater human consumption during the pressure of the motor rotor.Before the pressure, stack each component on the operating table of the hydraulic press. The manual adjustment of the positioning accuracy can easily lead to insufficient positioning acc...
