Four sets of mechanical valves, namely the first roller mechanical valve 11, the second roller mechanical valve 12, the third roller mechanical valve 13, and the fourth roller mechanical valve 14, are correspondingly installed on the upper surface of the cam control mechanism base plate 1. Each set of cam plates controls one set of mechanical valves.

[0033] The assembly mechanism base plate 19 is equipped with four sets of cylinders: a first cylinder 15, a second cylinder 16, a third cylinder 17, and a fourth cylinder 18. Each set of cylinders is connected to a mechanical valve, which controls the operation of the cylinder. The first cylinder 15 and the third cylinder 17 are horizontal drive cylinders, while the second cylinder 16 and the fourth cylinder 18 are vertical drive cylinders.

[0034] The first cylinder 15 is located on the right side of the assembly mechanism base plate 19. The first cylinder 15 is fixedly connected to the assembly mechanism base plate 19 via the cylinder bracket 20. The telescopic end of the first cylinder 15 is fixedly connected to the connecting plate 21. The connecting plate 21 is fixedly connected to the sliding plate 22. The sliding plate 22 is slidably connected to the guide rail 23. The guide rail 23 is fixedly installed on the surface of the assembly mechanism base plate 19. The second cylinder 16 and the fourth cylinder 18 are installed on the sliding plate 22. The first cylinder 15 drives the connecting plate 21 to move the sliding plate 22 linearly along the guide rail 23, thereby driving the second cylinder 16 and the fourth cylinder 18 to move linearly.

[0035] A fixed frame 29 is provided on the sliding plate 22. The telescopic end of the second cylinder 16 is rotatably connected to the second lever 31. The front end of the second lever 31 is fixedly installed with the part pressure head 33. The middle part of the second lever 31 is rotatably connected to the fixed frame 29.

[0036] The telescopic end of the fourth cylinder 18 is rotatably connected to the first lever 30. The first lever 30 is rotatably connected to the fixing frame 29. The bushing pressure head 32 is fixedly installed at the front end of the first lever 30. The telescopic end of the fourth cylinder 18 drives the first lever 30 to make lever movements, so that the bushing pressure head 32 at its front end presses down on the assembly 37, pressing the bushing 36 into the rubber ring 35.

The pre-assembled assembly 37, consisting of bushing 36 and rubber ring 35, is placed in the assembly placement station 27. The motor 2 is started, and the motor 2 drives the belt 38 to rotate the cam spindle 5. The four sets of cam plates sequentially activate the four sets of mechanical valves, which in turn activate the four sets of cylinders. The first cylinder 15 is activated, and the sliding plate 22 drives the second cylinder 16 and the fourth cylinder 18 to move towards the square base 24. Subsequently, the second cylinder 16 is activated, driving the zero through the second lever 31. The pressure head 33 moves downward, pressing the bracket part 34 to further fix it. Then the third cylinder 17 is activated, driving the positioning block 26 and the slider 25 to move towards the square base 24. The positioning block 26 pushes the assembly 37 into the bracket part 34. Then the fourth cylinder 18 is activated, driving the first lever 30 to move the bushing pressure head 32 downward, pressing the bushing 36 to ensure that the bushing 36 is pressed to the bottom of the rubber ring 35. After the above actions are completed, the four sets of cam plates continue to rotate and close the four sets of mechanical valves in sequence. The mechanical valves close the corresponding cylinders in sequence, and the tooling returns to the initial state.

[0040] Using the aforementioned semi-automatic tooling to assemble bracket parts 34 and assembly parts 37 can solve the problem of not being able to press all the way down, greatly improve the yield rate, and significantly increase production efficiency to meet customer needs.
