Description

Technical Field

[0001] The invention belongs to the technical field of generator rotor processing, and in particular relates to an auxiliary device for generator rotor processing. Background Art

[0002] A generator is a mechanical device that converts mechanical energy into electrical energy. It is driven by a turbine, steam turbine, diesel engine or other power machinery, and converts the energy generated by water flow, air flow, fuel combustion or nuclear fission into mechanical energy and transmits it to the generator, which then converts it into electrical energy. Generator rotor The rotating part of the generator. It is mainly composed of conductive rotor windings, magnetic core, rotor shaft extension, guard ring, center ring and fan, etc.

[0003] During the generator rotor processing, multiple sets of metal rods need to be inserted into the rotor core. During the generator rotor processing, they need to be manually inserted into the rotor core and measured to ensure that the two ends are the same distance. Then the metal rods are manually knocked to bend them for subsequent welding. However, since the rotor core is relatively heavy, the workers insert the metal rods slowly, which reduces the generator rotor processing efficiency. Summary of the invention
