Abstract:In order to solve the problem of the ring bar on the spinning frame that the malposition of the hole ofφ6.2 mm and the M6 hole of the support block of the ring bar on the lifting cross bar，and the failed to connect or install the malposition of screw and hole，the 8D method is applied.Through the implementation and analysis of the four stages of quick response，temporary corrective measures，root cause determination，and permanent corrective measures， the combined working assembly of the ring bar lifting device is restored，and dimensional accuracy is guaranteed.The straightening process is increased，and the hole of φ6.2 mm on the ring bar is changed to the slotted hole of φ6.2 mm×8.0 mm to solve the installation problem of the ring bar.It is pointed out that using the 8D method can find out the root cause of the problem，prevent the recurrence of the problem，and improve the comprehensive ability of the team to solve the problem.
Key Words:spinning frame；ring bar；8D method；lifting device；bearing；slotted hole；dimension chain
