Abstract
The invention discloses a positioning, loading and unloading device for an ultra-thin-walled cylinder piece. The positioning, loading and unloading device comprises a stepped mandrel, a positioning regulating ring fixed to the regulation portion of the mandrel through bolts, and a cylindrical core model positioning body with a stepped hole which is matched with the regulation portion of the mandrel in outer diameter and formed in the center. The core model positioning body is arranged outside the regulation portion of the mandrel through threads. A hollow cylindrical sliding body is arranged outside the core model positioning body and matched with the core model positioning body in a threaded mode. A left core model and a right core model are arranged outside a workpiece portion of the mandrel. A regulation cushion is arranged between the left core model and the right core model. A regulation base is arranged outside the press-fitting portion of the mandrel through threads. One end of the regulation base is fixedly connected with the right core model through a pressing plate and a set screw. A press-fitting body with a reducing hole formed in the center is arranged outside the regulation base through threads. The positioning, loading and unloading device solves the process technology problem that the workpiece loading and unloading difficulty is high when an ultra-thin-walled part and the mandrel are matched in a transition mode, ensures machining accuracy and improves loading and unloading efficiency.
