AI Technical Summary

Technical Problem

In the prior art, due to the initial placement of the wind power main flange during drilling, the clamping block is inactive and the part is then abutted, causing the flange to slide on the workbench, causing wear and affecting the passing rate of the flange.

Method used

A special machine for drilling and milling of the wind power main flange outer diameter drilling and milling CNC is designed, adopting structures such as support seats, processing parts, clamping blocks, winding components and auxiliary positioning components. Through the winding components, the clamping blocks are driven to slide, and the flange is automatically centered and clamped and positioned, and an elastic abutment block is set on the clamping block to reduce the initial impact force and avoid wear.

Benefits of technology

Automatic centering and clamping positioning of the wind power main flange is realized, avoiding wear caused by flange and work surface, extending the service life of the clamping block and flange, and improving the processing quality and pass rate of flange.

Abstract

The invention discloses a CNC machine for drilling and milling the outer diameter of a wind turbine main engine flange and a method for using the machine, and belongs to the technical field of CNC machines for drilling and milling. The CNC machine for drilling and milling the outer diameter of a wind turbine main engine flange comprises a processing table, and also comprises: a support seat, the support seat is fixedly arranged on the processing table, and is used to support the flange of the wind turbine main engine, and a plurality of balls are arranged on the top of the support seat; a processing part, the processing part is arranged on the upper side of the processing table through a connecting plate, and is used to process the flange of the wind turbine main engine placed on the support seat; a clamping block, the clamping block is slidably connected to the processing table, and a plurality of clamping blocks are arranged and are evenly arranged on the processing table in a circle; the invention facilitates automatic centering and clamping of the flange, and when the flange is pushed during the clamping period, wear of the flange and the work table surface is effectively avoided, and after the pushing is completed, the contact surface with the bottom wall of the flange is automatically increased, thereby increasing the friction between the clamping block and the flange, improving the stability of the flange clamping, and ensuring the flange processing quality.
