Abstract:In order to meet the mass production requirements of the main machine and improve the processing efficiency and quality of the JWF1579 middle wallboard for cotton ring spinning frame，the structural characteristics and processing requirements of the side hole of spindle rail bracket of the middle wallboard are analyzed，and the processing technology of the new middle wallboard is improved from the aspects of processing equipment，parts structure and cutter.It is pointed out that the φ10.2 mm coring bit of the middle wallboard side face is replaced by φ10.2/φ15H10 special integrated cutter，so as to solve the shortage of working position and realize the processing of all holes of spindle rail bracket and collective doffing bracket on middle wallboard with the existing special machine in one process.The process time is saved by 28 min.The complex engineering step is used to realize multi-cutter piece processing and improve the processing efficiency.The cost of single piece processing is saved by 73.33 yuan.M12/φ15H10 countersunk pin screw hole is processed at one time，the coaxiality of the two is improved，and the machining quality is improved.The hydraulic clamping device is used to reduce deformation and ensure the consistency of the parts.
Key Words:ring spinning frame；middle wallboard；spindle rail bracket；collective doffing bracket；countersunk pin screw hole；special integrated cutter
