Description

Technical Field

[0001] The utility model relates to the field of wind power bearing retainer processing, in particular to a special positioning jig for wind power bearing retainer processing. Background Art

[0002] In the wind power generation system, the bearing cage is a key component installed around the bearing to support and fix the bearing. In order to ensure the stability and accuracy of the bearing, as well as the performance and reliability of the wind power generation system, the process of manufacturing the wind power bearing cage requires high-precision processing and positioning. The special positioning jig is a tooling fixture used to position the workpiece, which is designed and manufactured to meet the processing requirements of specific workpieces.

[0003] In the prior art, some wind turbine bearing retainers are usually placed on a positioning jig, and a well-designed positioning interface or fixture is used to ensure that the bearing retainer can be accurately positioned and fixed on the positioning jig. However, during use, although the bearing retainer can be accurately positioned and fixed on the positioning jig, it is unable to clamp wind turbine bearing retainers of different sizes. If the positioning jig cannot clamp wind turbine bearing retainers of different sizes, the processing range will be limited. Wind turbine bearing retainers of different specifications and sizes require different clamping methods and support mechanisms. If the positioning jig does not have this flexibility, it cannot adapt to the processing requirements of bearing retainers of different sizes during the processing. Therefore, in view of the above problem, a special positioning jig for processing wind turbine bearing retainers is proposed. Utility Model Content
