Shape righting tool and method for nonmetallic thin-walled part

The invention discloses a shape righting tool and method for a nonmetallic thin-walled part and belongs to the field of machining. The shape righting tool for the nonmetallic thin-walled part comprises a base, an inner core and an outer cylinder, an inner core groove and an outer cylinder groove are formed in the base, the inner core is mounted in the inner core groove, the outer cylinder is mounted in the outer cylinder groove, thus the inner core and the outer cylinder are detachably fixed to the base, the outer cylinder sleeves the periphery of the inner core, and a shape righting space isformed between the inner wall of the outer cylinder and the outer wall of the inner core. The shape righting tool and method for the nonmetallic thin-walled part aim at solving the technical problem of deformation of the nonmetallic thin-walled part, through the shape righting space between the inner core and the outer cylinder, the nonmetallic thin-walled part can be subjected to shape righting automatically under the he
