Detailed Implementation

[0038] The present invention will now be described in further detail with reference to the accompanying drawings.

[0039] like Figure 1-5 As shown, this utility model discloses an automatic press-fitting device for a fuel tank isolation valve, comprising:

[0040] Rack 1;

[0041] The press-fitting assembly includes multiple press-fitting heads 2 and a lower presser 3, wherein the lower presser 3 controls the press-fitting heads 2 to move up and down.

[0042] Mounting bracket 4 is used to receive the product;

[0043] The chip removal component 5 is used to remove chips generated during the pressing process.

[0044] The advantages of adopting the above technical solution are that it enables the press-fitting of the bushing 11, sealing ring 12 and guide sleeve 13 of the fuel isolation valve, improves processing efficiency, and cleans up debris during the assembly process to ensure product quality.

[0045] The pressing head 2 includes a bushing pressing head 21, a sealing ring pressing head 22, and a guide sleeve pressing head 23. Movable blocks 24 are connected to the upper sides of the bushing pressing head 21, the sealing ring pressing head 22, and the guide sleeve pressing head 23. A translation plate 25 is installed on the frame 1. The movable blocks 24 are connected to the translation plate 25. There are three movable blocks 24, which are fixedly installed to the bushing pressing head 21, the sealing ring pressing head 22, and the guide sleeve pressing head 23 respectively. They are also fixed to the translation plate 25 with screws. A certain distance is left between the three movable blocks 24. The three pressing heads 2 are set up to achieve individual pressing of a single part, ensuring proper pressing. The movable blocks 24 drive the three pressing heads 2 to move, realizing the switching of the pressing heads 2. The translation plate 25 is equipped with multiple position sensors, such as photoelectric switches, to detect the position of the three pressing heads 2.

[0046] In addition, the frame 1 is provided with a back plate 6, and a transverse moving module 62 is installed on the back plate 6. The transverse moving module 62 drives the translation plate 25 to move. The transverse moving module 62 can be a ball screw module to ensure the positional accuracy of the pressing head movement. The back plate 6 is also provided with a guide rail 61, which is horizontally installed on the back plate 6. A slider is provided on the guide rail 61, and the slider is fixed to the translation plate 25. The translation plate 25 moves along the guide rail 61. The transverse moving module 62 drives the translation plate 25 to move horizontally, so that the corresponding pressing head 2 is located above the position to be pressed, waiting for the pressing part 3 to be pressed down. At the same time, the heights of the three pressing heads 2 are different to ensure that the three parts are pressed into place.

[0047] Furthermore, the bottom of the guide sleeve pressing head 23 is provided with a suction hole, which is connected to an air pipe 26. The suction hole is located at the bottom of the guide sleeve pressing head, and the air pipe 26 is fixed to the side of the guide sleeve pressing head 23 through an air pipe 26 connector. The air pipe 26 is connected to a flow meter, which displays the working status of the suction hole. The air pipe 26 is connected to a vacuum generator, which continuously draws air during the pressing process. When the guide sleeve 13 is sucked onto the guide sleeve pressing head, the flow meter displays a flow rate of zero, indicating that the guide sleeve 13 has been properly adsorbed and the next operation can be carried out.

[0048] The suction hole is used to pre-fix the guide sleeve 13, fix the guide sleeve 13 on the guide sleeve pressing head 23, so that the guide sleeve 13 moves up and down with the guide sleeve pressing head 23, reducing the deformation of the guide sleeve 13 during pressing.

[0049] In some implementations, the chip removal assembly 5 includes: a connecting plate 51, a chip suction head 52, and a moving arm 53. The chip suction head 52 is connected to the connecting plate 51, and the moving arm 53 is connected to the connecting plate 51, driving the connecting plate 51 to move. The chip removal assembly 5 also includes a horizontal cylinder and a vertical cylinder. The horizontal cylinder is mounted on the frame 1, and its output end is connected to the vertical cylinder. The extended end of the vertical cylinder is fixedly connected to the moving arm 53. The connecting plate 51 is fixedly mounted on the end of the moving arm 53, and the chip suction head 52 is fixedly mounted on the bottom of the connecting plate 51. The chip suction head 52 is moved in both horizontal and vertical directions by the horizontal cylinder and the vertical cylinder.

[0050] Furthermore, the chip removal assembly 5 also includes a receiving tray 54. After the moving arm 53 retracts, the chip suction head 52 is located on the upper side of the receiving tray 54. The receiving tray 54 is fixedly installed and used to receive the chips sucked up by the chip suction head 52. When both the horizontal cylinder and the vertical cylinder extend, the chip suction head 52 is located at the pressing point inside the product and sucks out the chips. Then the horizontal cylinder and the vertical cylinder retract, the entire device continues pressing, and the chip suction head 52 returns to its initial position, located on the upper side of the receiving tray 54.

[0051] The shaving head 52 is a cylinder with a diameter of 8-12mm. A coil is wound inside the cylinder, and the coil is connected to an electric wire, which is connected to a power source. When the coil is energized, the entire shaving head 52 becomes magnetic, with a magnetic field strength of ≥800 Gauss. It attracts debris through magnetic force. When the shaving head 52 returns to its position on the upper side of the receiving tray 54, the coil is de-energized. At this time, the shaving head 52 loses its magnetism, and the debris falls onto the receiving tray 54. The shaving head 52 repeats its work, and only the receiving tray 54 needs to be cleaned periodically.

[0052] In some implementations, the mounting base 4 is provided with a base plate 41 and a positioning block 42. The positioning block 42 is connected to the base plate 41 and is provided with a limiting groove 43 for limiting the product. The positioning block 42 is used to position the product, and the base plate 41 serves to support it, preventing the product from shaking during the pressing process and ensuring that the pressing is in place.

[0053] In some implementations, the frame 1 is provided with multiple containers 7, which contain bushings 11, sealing rings 12 and guide sleeves 13 respectively, to facilitate subsequent pressing operations.

[0054] In some implementations, a support column 8 is provided on the frame 1, and a top plate 81 is provided on the top of the support column 8. The pressing component 3 is fixed to the top plate 81. The pressing component 3 drives the translation plate 25 to move up and down along the support column 8. The pressing component 3 is a cylinder, which is fixedly installed on the top plate 81 as a whole. The output end is set downward and passes through the top plate 81 and is fixed to the back plate 6. The back plate 6 is provided with a bushing so that it can move up and down along the support column 8.

[0055] The working process is as follows: First, the operator places the product on the mounting base 4, and positions the bushing 11 and sealing ring 12 in the product's pressing position. The guide sleeve 13 is then attached to the guide sleeve pressing head 23. The control switch is activated, causing the translation plate 25 to move horizontally. The bushing pressing head 21 presses down on the bushing 11, and then, driven by the lower pressing component 3, the bushing pressing head 21 descends, pressing the bushing 11 into place. Then, the moving arm 53 extends, and the chip suction head 52 is energized to collect the generated chips. After collection, the chip suction head 52 returns to its original position and is de-energized, allowing the chips to fall onto the receiving tray 54. Next, the translation plate 25 continues to move horizontally, aligning the sealing ring pressing head 22 with the sealing ring 12. The lower pressing component 3 presses down, pressing the sealing ring 12 into the product. The translation plate 25 continues to move horizontally, with the guide sleeve 13 positioned on top of the product. The lower pressing component 3 presses down, completing the pressing of the guide sleeve 13. The operator then removes the pressed workpiece and continues to the next pressing operation. Figure 6 This is an assembly diagram of bushing 11, sealing ring 12 and guide sleeve 13.

[0056] For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
