AI Technical Summary
Existing thin-walled external gear rings are prone to microscopic elastic concave deformation and end face springback twisting during turning due to clamping force, which affects machining accuracy.
A magnetic attraction unit is used for initial adsorption, combined with an axial pushing unit and a radial expansion unit to provide uniform internal support around the thin-walled external gear ring. A negative pressure unit is used to achieve axial contraction and radial expansion, ensuring the coaxiality of the workpiece and the rotating sleeve and avoiding stress concentration.
It effectively improves the flatness and runout accuracy of end face turning, protects the tooth profile and thin-walled structure from damage, and avoids the microscopic elastic concave deformation caused by traditional clamping methods.
