Gantry frames are respectively set up on both sides of the slide where the three workstations stop for processing. On each gantry, there is a workpiece grasping device that is driven up and down and located directly above the support frame. Each gantry is provided with a robotic arm that can be driven up and down and can be driven to move laterally to the middle and left on the left and right sides. A processing tool is provided on the front end of the robotic arm. The workpieces to be processed on the three workstations are processed synchronously in different steps. The workpiece processed at the front workstation is successively taken over by the support frame of the rear workstation for the next round of continuous processing until it is taken away after processing is completed.

[0018] The linear motion mechanism and linear module are equipped with protective covers.

[0019] Equipment operation process: The operator stands at the loading door at the rear end of the equipment. The support frame fixed at the first station on the slide of the linear motion mechanism is close to the loading door. The operator places the blank of the workpiece to be processed on the support frame of the first station. The support frame on the second station is just below the first processing station. The support frame can receive the workpiece to be processed that has been processed at the first processing station. The support frame on the third station is just below the second processing station. The support frame can receive the workpiece to be processed that has been processed at the first processing station.

[0020] The linear motion mechanism starts, and its slide moves forward. The three support frames stay at three processing stations. The linear module 61 is driven downward, and the grabbing head 51 grabs the blank to be processed from the support frame of the first station and moves it upward. The rotating shaft 81 drives the grabbing head 51 to drive the blank to rotate. The mechanical left arm 71, the mechanical left arm 2 72, the mechanical right arm 1 73, and the mechanical right arm 2 74 can move up, down, left, and right with the cooperation of the linear module 2 62 and the linear module 3 63. The tool head and drill bit at the front end of the robotic arm work in coordination to perform special-shaped rough outer circle, stop cutting, and oil hole drilling processes on the blank.

[0021] Simultaneously, at the second processing station, left arms 3 75 and 76, in coordination with linear modules 5 65 and 66, can move up and down, left and right. The cutting heads at the front of the arms perform ring grooving, top surface finishing, profile finishing, and chamfering on the workpiece. Upon completion, linear module 4 64 descends, and gripper head 2 52 picks up the finished semi-finished product.

[0022] Simultaneously, at the third processing station, robotic left arm 4 77, right arm 4 78, and right arm 5 79, coordinated by linear modules 8 68 and 9 69, move up and down, left and right. Tools at the front of the robotic arms perform rough boring, snap ring grooving, internal and external chamfering, and special-shaped finish boring on the workpiece. Upon completion, linear module 7 67 descends, grabs the finished product with gripper head 3 53, and then transfers it to the outside of the machine via linear module 10 60 for unloading by the operator.

[0023] After the processing is completed, the slide of the linear motion mechanism retreats to its original position to the rear end, and the support frame on the second station is just below the first processing station. The linear module 1 61 is driven downward to place the semi-finished workpiece completed at the first processing station on the support frame of the second station. The support frame on the third station is just below the second processing station. The linear module 4 64 is driven downward to place the semi-finished workpiece completed at the second processing station on the support frame of the third station. At the same time, the operator places a new workpiece blank to be processed on the support frame of the first station, and then the slide of the linear motion mechanism repeats its forward movement. The three support frames stay at the three processing stations for the next round of repeated operations.

[0024] During the same period of time, more than a dozen processing operations are carried out simultaneously on the workpieces at three processing stations in a cyclical manner, and products can be output in each cycle.
