Abstract:In order to solve the problems of long production cycle and unstable quality of the rocker arm of draft shift gear for cotton ring spinning frame，the present situation of difficult clamping and positioning，high machining accuracy and difficulty in the existing process is analyzed，and the improvement scheme is put forward following the principle of process concentration.The improvement scheme using CNC lathe instead of ordinary processing equipment，once clamping，once positioning to complete the processing content of φ52H7，φ55 mm，φ62H7 and base surface，to improve the position accuracy and perpendicularity of base surface and hole；the outer circle of the blank bottom surface is changed from an arc to an integral circle to ensure the adjustment space and improve the clamping stability.The practical results show that after the improvement of the process，the processing process of the rocker arm of draft shift gear is shortened，the clamping times are reduced，the clamping stability is improved，the black skin problem is solved，and the production efficiency and product quality are improved.
Key Words:rocker arm of draft shift gear；cotton ring spinning frame；process concentration；CNC lathe；accuracy of position
