Abstract:In order to ensure the symmetry and dimensional accuracy of thin-walled bearing shell milling flat and improve its production efficiency，the structure and processing difficulties of the bearing shell are analyzed,and its machining method is improved.A new fixture for thin-walled bearing shell milling flat is designed by using tangelan collet.It is pointed out that the new fixture has the advantages of automatic centering and uniform clamping force；it is convenient for adjustment and operation，and it has good versatility;after machining thin-walled bearing shell with new fixture,qualified rate of products is high,and high qualified rate of products，and its processing efficiency has greatly improved.The design can provide a new idea for other fixtures for thin-walled bearing shell.
Key Words:thin-walled bearing；flat；fixture；collet；automatic centering
