Description

Technical Field

[0002] In recent years, with the rise of the wind power industry, the power of wind turbines has continued to increase, and the speed of motor model replacement has continued to accelerate, resulting in an increase in tooling investment costs. In this environment, higher requirements are placed on the versatility and convenience of tooling. Improving tooling versatility and work efficiency through mechatronic methods has become a better solution.

[0003] In order to advance the electromechanical level of tooling, the stator vertical wire embedding and head-joining tooling used in wind turbine manufacturing needs to be redesigned to meet the requirements of versatility and efficiency improvement.

[0004] Existing technical solutions:

[0005] The existing large-scale generator stator vertical wire embedding and head-joining platform is made of multiple wooden pedals. Different types of motors require customized special wooden pedals. When in use, the pedals and stator supports need to be manually carried and placed, which causes repetitive production and repetitive operation of tooling, and requires occupation of factory land to store the pedal tooling.

[0006] Defects of the existing technology:

[0007] The prior art wire embedding and header station is a wooden pedal, which has a fixed structure and poor adaptability to stators with different diameters. It is necessary to use pedals of different sizes for different stator outer diameters, and each use requires manual handling.

[0008] The stator support in the prior art wire embedding and header station is a steel structure. When supporting stators of different structures, manual handling and position adjustment are required, and the position adjustment is required during the stator hoisting process, which poses certain safety hazards.

[0009] The existing wire embedding and header merging station has a fixed size of wooden pedal structure, so it is impossible to complete the wire embedding and header merging work on one station, and multiple lifting is required. Summary of the invention
