[0002] The gear shift screw is an important transmission component in automobiles, mainly used in the shifting mechanism of manual transmissions. The machining quality of the gear shift screw directly affects the working accuracy and reliability of the shifting mechanism. Therefore, high-precision gear shift screws have very high requirements in terms of appearance, dimensional tolerances, surface roughness, and geometric tolerances.

[0003] In the traditional machining process of external threads for automotive gear shift screws, conventional machining is mostly carried out using ordinary lathes or CNC lathes, along with manual loading and unloading. This not only consumes a lot of human resources and results in low equipment utilization, but also requires repeated calibration of the workpiece position during machining, ultimately leading to long processing cycles, low production efficiency, and high scrap rates.

Subsequently, the second motor 203 drives the slider 211 to move vertically downward, and the first cylinder 205 pushes the first push plate 212 to move horizontally, preparing for the gripping of the unprocessed lead screw 6. The first finger cylinder 206 drives the first pneumatic manipulator 208 to open and close, steadily gripping the unprocessed lead screw 6. Then, the first motor 202 drives the moving component, carrying the unprocessed lead screw 6 along the horizontal arm 204 to the lead screw processing device 5. At the lead screw processing device 5, the second finger cylinder 207 drives the second pneumatic manipulator 209 to clamp the processed lead screw 7. Then, the third motor drives the three-jaw chuck, which releases the processed lead screw 7. The first pneumatic manipulator 208 then transports the unprocessed lead screw 6 to the three-jaw chuck. The third motor drives the three-jaw chuck to close, firmly clamping the unprocessed lead screw 6. The fourth cylinder then drives the milling base 501 to move horizontally towards the feeding mechanism. One end of the unprocessed lead screw 6 extends into the milling cutter head 503. The milling motor then drives the milling cutter head 503 to rotate, performing precision milling thread processing on the unprocessed lead screw 6 clamped on the three-jaw chuck. Simultaneously, the processed lead screw 7 is conveyed to the receiving conveyor belt. This processing procedure is repeated multiple times.
