Problems solved by technology

[0002] The motor rotor is generally formed by a plurality of steel sheets connected in series on the rotor shaft. The steel sheet and the rotor shaft are interference fit. In order to facilitate assembly, the existing motor rotor assembly method generally uses the rotor shaft Cool in liquid nitrogen, and insert the rotor shaft into the rotor shaft installation hole of the steel sheet after being cooled and shrunk. At present, the assembly of the extremely low-temperature rotor shaft into the steel sheet is done manually, which is easy to frostbite and extremely dangerous. Big
[0003] Alternatively, put the steel sheet into heating equipment such as an oven to heat it to expand, then take out the steel sheet from the oven, and then insert the rotor shaft into the rotor shaft mounting hole of the steel sheet. When quickly assembling the rotor shaft and the steel sheet, the assembly may not be possible or the assembly effect is not good, which increases the scrap rate. On the other hand, the high temperature steel sheet may burn the workers, which is very dangerous

Abstract

The invention provides an assembly apparatus and an assembly method of a rotor shaft of a motor. the assembly apparatus for motor rotor shafts includes manipulators, silicon steel sheet loading stations, a heating assembly station, and rotor shaft loading stations; a load station of silicon steel sheet comprises a manual assembly station, a pressing device and a jig cooling station. that heatingassembly station comprises a heating device, a heating rod is arranged on the heating device, the heat rod comprises at least one helical conductive member, and at least one metal rod is arranged in each helical conductive member. the electric motor rotor shaft assembly device of the invention combines the heating rod and the silicon steel sheet to form eddy current, and realizes the self-heatingof the silicon steel sheet by utilizing the eddy current induction principle. The heating mode not only has extremely fast heating speed, but also the heating rod itself does not heat, thus improvingthe safety of the operation of the device.
