AI Technical Summary

⚠Technical Problem

During the precision machining process of the planetary carrier rings for wind turbines, the large datum surface can easily cause the form and position tolerances to exceed the tolerances, making it difficult to meet the requirements of high-precision machining.

⚗Method used

A support device for precision machining of wind turbine planetary carrier rings is adopted. It utilizes a combination structure of fixed support blocks and floating support blocks. The workpiece is stably fixed by magnetic adsorption and spring adjustment. The floating block of the floating support block cooperates with the guide column and spring to compensate for the unevenness of the workpiece reference surface and ensure machining accuracy.

🎯Benefits of technology

The precision machining of the wind turbine planetary carrier rings achieved a flatness of less than 0.05mm, meeting the requirements for geometric tolerances and improving machining accuracy and stability.
