[0037] like Figure 6As shown, the transplanting mechanism 4 also includes a transplanting assembly, which includes a second mounting bracket 45, a second linear module 46, a transplanting seat 47, and a lifting cylinder 48. The second mounting bracket 45 is fixed above the workbench 1, and the second linear module 46 is provided on its front side. The output end of the second linear module 46 is provided with the transplanting seat 47 for driving the transplanting seat 47 to move horizontally. The lifting cylinder 48 is provided above the transplanting seat 47, and the output end of the lifting cylinder 48 is provided with a positioning seat 49. The upper end of the positioning seat 49 is provided with a positioning hole 491 for placing a gear.

The round hole is a stepped hole, including a small round hole at the lower end and a large round hole at the upper end, which better positions the gear and can accommodate the positioning of two sizes of gears. In this embodiment, linear module 1 42 and linear module 2 46 are translational components consisting of a telescopic cylinder or a lead screw and slide rail combination, and both are equipped with sensors to control the translational stroke to ensure accurate docking positions between the material picking component and the transfer component, as well as between the transfer component and the pressure head.

[0038] The working principle of this utility model is as follows: Initially, the storage bins 32 on the turntable 31 are full of material. The material picking component moves to the gear picking position to pick up the gear, and then drives the gripper cylinder 44 to move above the positioning seat 49 and place it into the positioning hole 491 on the positioning seat 49. Then, the positioning seat 49 moves directly below the pressure head 21 through the linear module 2 46. At the same time, material is picked up from the roller conveyor (drive shaft) and placed on the tooling. The lifting cylinder 48 drives the positioning seat 49 to rise and approach the pressure head 21. The centering component is activated to insert the positioning rod 23 into the gear inner hole, centering the gear and the pressure head 21. Then, the pressure head 21 magnetically attracts the gear on the positioning seat 49. Pressing begins. When the gear approaches the tooling 5, the centering component resets, so that the gear remains aligned with the pressure head during the feeding to the pressure head and the pressing descent stroke. Finally, the pressing mechanism 2 presses the gear onto the drive shaft, automatically completing the gear pressing.

[0039] In summary, this utility model can automatically press-fit gears, improving production efficiency. Furthermore, by centering the press head and gear before the press head picks up the gear, the press head and gear are always aligned, ensuring the accuracy of pressing and improving production quality.
