The clamping plate 5 is connected to the wheel hub, and the wheel hub is tightened by the middle clamping bolt. The connection structure between the turntable 9 and the inclined block 6 includes: a cylindrical helical compression spring 12 extending in the radial direction is provided on the turntable 9, a groove body is provided on the outer side of the inclined block 6, the cylindrical helical compression spring 12 presses into the groove body, and the inner wall of one side of the groove body is an inclined surface.

A plurality of tightening seats 10 are provided at the upper edge of the fine turning tooling base 1.

[0018] Technical principle: 1. This device is used for fine turning of the stop surface of wind turbine end cover.

[0019] 2. Use two positioning blocks 3 to initially position from the diameter direction, and tighten with diagonal tightening bolts to ensure that the positioning surface is reliably positioned.

[0020] 3. The middle clamping plate 5 is connected to the wheel hub, and the wheel hub is tightened by the middle clamping bolt to ensure that the positioning surface is reliably positioned.

[0021] 4. 20 lifting columns 8 are evenly distributed around the periphery to support the rough surface of the workpiece during semi-finishing turning to facilitate turning.

[0022] The lifting function is realized by rotating the inclined block 6: the handle 11 rotates, driving the turntable 9 to rotate, and the turntable 9 drives the inclined block 6 to rotate through the cylindrical helical compression spring 12, and the inclined block 6 pushes the lifting column 8 to support the workpiece.
