The controller then sends a signal to the rotary mechanism 5, and the rotary mechanism 5 receives the signal and drives the rotary table 6 to rotate by one hundred twenty degrees so that the second feed mechanism 8 rotates to the radial position of the electric rotary table 3. The controller then sends a signal to the linear motion mechanism 2 to drive the rotary table 6 and the second feed mechanism 8 to close and cut the gear sleeve along the radial direction of the electric rotary table 3. When the tool point of the tool of the second feeding mechanism 8 moves to a set point, namely the distance between the tool point and the bottom of the shifting fork groove and the distance between the tool point and the inner wall of the upper side of the shifting fork groove are equal, the controller sends a signal to the linear motion mechanism 2 and the second feeding mechanism 8, the linear motion mechanism 2 and the second feeding mechanism 8 move at a constant speed after receiving the signal, the linear motion mechanism 2 controls the rotating mechanism 5, the rotary worktable 6 and the second feeding mechanism 8 to continue to move along the radial direction of the electric rotating platform 3, and the first feeding mechanism 7 drives the tool to move vertically and downwards. The lower end face of the cutter of the second feed mechanism 8 is always parallel to the end face of the gear sleeve in the moving process. And when the tool nose of the second tool feeding mechanism 8 moves to the bottom of the shifting fork groove, the second step of turning operation is completed. Then the controller sends a signal to the linear motion mechanism 2 and the second feed mechanism 8, the linear motion mechanism 2 drives the rotary mechanism 5 and the rotary worktable 6 to drive the second feed mechanism 8 to radially retract along the electric rotary table 3 after receiving the signal, the second feed mechanism 8 drives the cutter to reset along the vertical direction after receiving the signal, and the accurate positioning can be realized through the induction assembly on the second feed mechanism 8. The controller then sends a signal to the rotating mechanism 5, and the rotating mechanism 5 receives the signal and drives the rotating table 6 to rotate by one hundred twenty degrees again so as to move the flattening mechanism 9 to the radial position of the electric rotating table 3. And then the controller sends a signal to the linear motion mechanism 2, and the linear motion mechanism 2 drives the rotary wheel mechanism 5, the rotary worktable 6 and the flat cutting mechanism 9 to radially approach the gear sleeve and cut the gear sleeve along the electric rotary table 3 after receiving the signal until the tool tip of the flat cutting mechanism 9 moves to the bottom of the shifting fork groove, so that the whole processing of the shifting fork groove is completed. Then the controller drives each component to reset and enables the electric rotating platform 3 to stop rotating, and the working personnel take down the gear sleeve which is finished to be processed to continue subsequent operation.
