Description

Technical Field

[0001] The present invention relates to the technical field of combined processing equipment, and in particular to an assembly device used for assembling a main rotor and a connecting piece of a generator. 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.

[0003] Structurally, a generator typically consists of a stator, rotor, end caps, and bearings. Specifically, the stator consists of the stator core, coil windings, a frame, and other structural components that secure these components; while the rotor consists of the rotor shaft, rotor core, windings, locating rings, and bearings.

[0004] In terms of working principle, the stator and rotor of the generator are connected and assembled by bearings and end covers, so that the rotor can rotate in the stator and cut the magnetic lines of force, thereby generating an induced electromotive force, which is led out through the terminal and connected to the circuit to generate current.

[0005] In terms of the production process, the various components that make up the generator stator, rotor, end cover, and bearings are first mass-produced and then assembled on specific equipment to obtain semi-finished or finished generators. Specifically, when assembling the generator rotor, due to the large number of components that make up the rotor, including the rotor shaft, locating ring, rotor core, and bearings, and the rotor core is composed of several connected laminations stacked together, the diversity of the assembled components and the specificity of the individual components increase the complexity of the assembly to varying degrees. As a result, when using existing equipment for generator assembly, the following problems often arise: 1. There are many assembly parts, which results in a single clamping method being unable to be applied to the clamping of different assembly parts, affecting the overall assembly accuracy.

[0006] 2. The problem of poor coordination and assembly continuity of multiple assembly mechanisms during the combined assembly process.

[0007] 3. Since the rotor core is composed of multiple connected laminations, it is difficult to accurately position and clamp each connected lamination during the loading process, and it is also impossible to ensure that the connected laminations will not shift during the assembly process.

[0008] In summary, the existing technology has obvious inconveniences and defects in actual use, so it is necessary to improve it. Summary of the Invention
