When the workpiece 10 is placed between the first pin 2312 and the second pin 2323, the workpiece 10 blocks the light emitted by the transmitter 2331. At this time, the receiver 2332 cannot receive the light emitted by the transmitter 2331. The pushing cylinder 2322 pushes the second pin 2323 to move to a position close to the first pin 2312 to cooperate with the first pin 2312 to clamp the workpiece 10. The controller 6 issues a command to start the motor 2321 to drive the second pin 2323 to rotate, thereby causing the workpiece 10 to rotate accordingly.

In this way, when the power member 52 is started, the press head 53 moves along the slide rail 54 in a direction close to the positioning seat 6 and contacts the assembly until the press head 53 completely presses the assembly and the workpiece 10 into place; under the action of the power member 52, the press head 53 moves along the slide rail 54 in a direction away from the positioning seat 6 until it moves to its original position.

[0033] Furthermore, the automatic pressing mechanism also includes a second barcode scanning gun 8, which is installed on the frame 1 and located on a side away from the workpiece clamping device 2, and the second barcode scanning gun 8 is used to scan the laser label on the turbine assembly.

[0034] Furthermore, the automatic press-fitting mechanism also includes a defective product storage box 9 , which is installed at the bottom of the frame 1 and is adjacent to the positioning seat 6 .

[0035] When in use, the workpiece is placed between the first pin 2312 and the second pin 2323. The first barcode scanner 22 is used to scan the laser label of the workpiece 10 and upload the scanning information to the controller 7. The workpiece 10 blocks the light emitted by the transmitter 2331. At this time, the receiver 2332 cannot receive the light emitted by the transmitter 2331. The pushing cylinder 2322 pushes the second pin 2323 to move to a position close to the first pin 2312 and cooperates with the first pin 2312 to clamp the workpiece 10. The controller 6 issues a command to start the motor 2321 to drive the second pin 2323 to rotate, thereby causing the workpiece 10 to rotate accordingly. The nozzle 33 applies grease so that the grease can be evenly applied to one end of the workpiece 10. At the same time, the indicator light 4 lights up and shows green.

[0036] When the indicator light 4 lights up and shows green, remove the workpiece 10 and place it on the positioning hole 62 of the positioning seat 6, and place the end of the workpiece 10 coated with grease in the direction away from the positioning seat 6, put the assembly part on the workpiece 10, and the controller 7 sends a command to start the power member 52, and the pressure head 53 moves along the slide rail 54 in the direction close to the positioning seat 6 to contact the assembly part until the pressure head 53 completely presses the assembly part and the workpiece 10 into place; when the pressure head 53 completely presses the assembly part and the workpiece 10 into place, the indicator light 4 lights up again and shows green, and the pressure head 53, under the action of the power member 52, moves along the slide rail 54 in the direction away from the positioning seat 6 until it moves to its original position.

[0038] The beneficial effect is that during the press-fitting process, there is no contact between the tool (drill) and the workpiece, which eliminates the noise generated during the tool drilling and pinning process. In addition, through the use of an industrial computer and a barcode scanner, the press-fitting mechanism can control the quality of the press-fitted finished product according to the batch number of the workpiece and the turbine assembly during the production process, greatly improving the traceability of the press-fitted finished product and facilitating the control of technical personnel.
