The control system identifies the state of the gear shaft processing machine tool 11 and controls the automatic loading and unloading device 2 to perform loading and unloading operations on the gear shaft processing machine tool 11. First, the sliding seat 23 drives the linear motor 24 and the pneumatic clamping claw 25 to move along the length direction of the slide rail 22 to the top of the gear shaft raw material tray 12, and the linear motor 24 is started to make the pneumatic clamping claw 25 descend, and the pneumatic clamping claw 25 clamps the gear shaft raw material tray 12 and places it. The linear motor 24 then drives the pneumatic claw 25 to rise, and the sliding seat 23 drives the linear motor 24 and the pneumatic claw 25 to move above the gear shaft processing machine 11, and then the linear motor 24 drives the pneumatic claw 25 to descend, and the pneumatic claw 25 places the gear shaft blank in the gear shaft processing machine 11, and finally, the linear motor 24 drives the pneumatic claw 25 back to the top of the gear shaft processing machine 11, and the gear shaft processing machine 11 clamps the gear shaft blank for processing; after the processing is completed, the pneumatic claw 25 descends again, clamps the processed gear shaft finished product, and moves it to the fixed cavity 14 of the gear shaft finished product tray 13.

[0055] After the processing of the finished gear shaft is completed, the first drive motor 3143 is started, and the first drive motor 3143 drives the drive screw 3141 to rotate, so that the limit support plate 315 moves along the height direction of the drive screw 3141, and the drive screw 3141 drives the limit support plate 315 to rise until it is out of the liquid surface of the cleaning liquid. The control system sends an instruction to the transfer device 4, and the base 43 drives the mechanical arm 42 to slide along the guide rail 44, so that the mechanical arm 42 clamps the finished gear shaft on the gear shaft finished product tray 13 and places it on the limit support plate 315, and then the first drive motor 3143 drives the drive screw 3141 to rotate, so that the limit support plate 315 and the finished gear shaft are immersed in the cleaning liquid, and the ultrasonic generator 312 is started to generate ultrasonic waves to clean the finished gear shaft in the cleaning liquid.

[0056] After cleaning is completed, the first drive motor 3143 drives the limiting support plate 315 to rise, and the limiting support plate 315 drives the finished gear shaft to separate from the liquid surface of the cleaning liquid. The control system controls the robotic arm 42 to clamp the finished gear shaft and place the finished gear shaft between the first support seat 531 and the second support seat 532, and starts the adjusting cylinder 535. The piston rod of the adjusting cylinder 535 pushes the first fixed top 533 to slide on the first support seat 531, so that the first fixed top 533 moves toward the second fixed top 534. The first fixed top 533 and the second fixed top 534 are respectively pressed against the center holes at both ends of the finished gear shaft to support and fix the finished gear shaft. The two-dimensional measuring instrument 51 projects the finished gear shaft in the vertical direction, thereby measuring the dimensional tolerance data of the finished gear shaft, and screens the products with excessive dimensional tolerances. The robotic arm 42 places the products with excessive dimensional tolerances in the waste collection box 55.

[0057] The mechanical arm 42 clamps the finished gear shaft with qualified dimensional tolerance and places it between the first support plate 5411 and the second support plate 5421, adjusts the driving cylinder 545, extends the piston rod of the driving cylinder 545, pushes the first support plate 5411 close to the second support plate 5421, so that the two movable tops 543 respectively abut against the two ends of the finished gear shaft, and supports and fixes the movable tops 543, and then starts the second driving motor 544, the second driving motor 544 drives the movable top 543 on the second supporting plate 5421 to rotate, and the movable top 543 on the second supporting plate 5421 drives the finished gear shaft and the other movable top 543 to rotate together. During the rotation of the finished gear shaft, the measuring head of the three-dimensional coordinate measuring instrument 52 contacts different positions of the finished gear shaft respectively, and measures the shape and position tolerance of the finished gear shaft; the mechanical arm 42 puts the products with unqualified shape and position tolerance into the waste collection box 55, and puts the products with qualified shape and position tolerance into the qualified product tray 56.

[0058] In particular, when the two-dimensional measuring instrument 51 and the three-dimensional coordinate measuring instrument 52 are working, the control system can transmit the measurement data to the gear shaft processing machine tool 11. The gear shaft processing machine tool 11 modifies the tool compensation data according to the dimensional tolerance data and optimizes the processing parameters according to the form and position tolerance data, thereby ensuring the dimensional consistency of the gear shaft product and improving the production quality of the gear shaft.

[0059] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
