[0003] The fuel tank isolation valve requires the installation of bushings, which need to be press-fitted. In the existing technology, manual press-fitting is generally used, which can only install one at a time, resulting in low efficiency and unreliable installation quality. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides an integrated press-fitting device for fuel tank isolation valve bushings, which can complete the press-fitting of multiple bushings at one time, ensuring accurate installation and improving installation efficiency.

[0005] Specifically, this utility model discloses an integrated press-fitting device for fuel tank isolation valve bushings, comprising:

[0006] frame;

[0007] The receiving component includes a receiving base, wherein the receiving base is provided with a positioning post for fixing the product;

[0009] The advantages of adopting the above technical solution are that it enables automatic pressing of bearing bushings, completes the pressing of multiple bushings at one time, has high efficiency, and ensures installation quality.

[0010] Furthermore, the receiving seat has two supporting legs, which are mounted to a base plate. The supporting legs have cavities inside, and the positioning post passes through the cavity and is fitted with a spring.

[0011] The advantage of adopting the above technical solution is that the support feet provide support, the positioning posts provide positioning, and the positioning posts can extend and retract without affecting the bushing pressing.

[0012] Furthermore, the top of the positioning post has a cylindrical head that extends into the product mounting hole for positioning the bushing before press-fitting.

[0013] The advantage of adopting the above technical solution is that the cylindrical head is used to position the bushing, so that the bushing is kept in a vertical position before pressing, ensuring accurate pressing position.

[0014] Furthermore, the pressing assembly includes a connecting plate, with receiving plates on both sides of the connecting plate, forming a receiving groove between the receiving plates, and a fixing plate connected to the top of the pressing head, the fixing plate being installed in the receiving groove.

[0015] The advantage of adopting the above technical solution is that the receiving groove is used to position the fixing plate, which facilitates the installation of the pressure head, and the fixing plate can be replaced when producing different models of products.

[0016] Furthermore, the receiving plate is provided with an adjusting rod for adjusting the position of the fixing plate.

[0017] The advantage of adopting the above technical solution is that the adjusting rod is used to fine-tune the position of the fixed plate so that the pressure head is aligned with the bushing to complete the pressing.

[0018] Furthermore, a support frame is installed on the frame, and a sensor is installed on the support frame for detecting the position of the bushing.

[0019] The advantage of adopting the above technical solution is that the sensor is set to sense the position of the bushing. After the bushing is in place, the pressing device presses down again to avoid the situation of empty pressure.

[0020] Furthermore, a second sensor is provided at the bottom of the receiving seat to sense whether the product is in place.

[0021] The advantage of adopting the above technical solution is that the sensor is used to sense whether the product is placed in place. If the product is not in place, the pressing device will not press down.

[0022] Furthermore, the pressing assembly also includes a mounting plate, which is provided with support columns and mounted on the frame. The mounting plate is provided with a driving component, the output end of which is connected to the connecting plate. The connecting plate and the mounting plate are connected via a guide shaft.

[0023] The advantage of adopting the above technical solution is that the connecting plate is pressed down by the driving component, and the mounting plate plays a role in installation and fixation.

[0024] Furthermore, a proximity sensor is also provided on the side of the positioning post.

[0025] The advantage of adopting the above technical solution is that the proximity sensor can detect whether the positioning column has moved to the correct position, so as to determine whether the bushing is properly pressed in place.

[0026] Furthermore, the bushing has a notch and a chamfer at the end.

[0027] The advantage of adopting the above technical solution is that the notch design prevents the bushing from breaking due to compression when it is pressed into the product, thus ensuring the quality of the bushing. Attached Figure Description

Detailed Implementation

[0037] The present invention will now be described in further detail with reference to the accompanying drawings.

[0038] like Figure 1-3 As shown, this utility model discloses an integrated press-fitting device for fuel tank isolation valve bushings, comprising:

[0039] Rack 1;

[0040] The receiving component includes a receiving base 2, wherein the receiving base 2 is provided with a positioning post 3 for fixing the product;

[0041] The pressing assembly includes a pressing head 4 that can move up and down, used to press down and press the bushing 11 into the product.

[0042] The advantage of adopting the above technical solution is that it realizes automatic pressing of bearing bushing 11, completes the pressing of multiple bushings 11 at one time, which is highly efficient and ensures the installation quality.

[0043] The receiving seat 2 has two supporting feet 21, which are installed on a base plate 7. The supporting feet 21 have cavities inside, through which the positioning post 3 passes. A spring 22 is sleeved on the spring 22, which is sleeved on the bottom of the positioning post 3. The bottom of the spring 22 abuts against the base plate 7. A limit step 33 is provided in the middle of the positioning post 3 to limit the position of the spring 22. A proximity sensor 32 is also provided on the side of the positioning post 3. The proximity sensor 32 can be an inductive proximity sensor. During the pressing process, the positioning post 3 will descend and the spring 22 will be compressed. At this time, the proximity sensor 32 will sense the position of the limit step 33, indicating that the positioning post has descended normally and reached the correct position, and the bushing 11 is pressed normally.

[0044] Furthermore, such as Figure 4-5 As shown, the top of the positioning column 3 has a cylindrical head 31, which extends into the product mounting hole and is used to position the bushing 11 before pressing. The product mounting holes are symmetrically arranged, and the top of the cylindrical head 31 extends out of the mounting hole. Before pressing, the bushing 11 is put on the cylindrical head 31 for pre-fixation, so that the bushing 11 is kept in a vertical position to ensure the pressing effect.

[0045] Bushing 11 has a notch, such as Figure 6 As shown, the bushing 11 is cylindrical in shape with a chamfer at the end. The notch extends through the entire bushing 11, giving it a certain compressibility when it enters the mounting hole, thus preventing breakage.

[0046] In some implementations, the pressing assembly includes a connecting plate 5, with receiving plates 51 on both sides of the connecting plate 5, forming a receiving groove between the receiving plates 51. The receiving plates 51 are locked and fixed to the connecting plate 5. The receiving plate 51 has an L-shaped cross-section and threaded holes on both sides. A fixing plate 41 is connected to the top of the pressing head 4, and the fixing plate 41 is inserted into the receiving groove. Threaded holes are also provided on the fixing plate 41 at corresponding positions to the receiving plates 51. The fixing plate 41 and the pressing head 4 can be fixed by welding, screw fastening, etc.

[0047] Furthermore, the receiving plate 51 is provided with an adjusting rod 52 for adjusting the position of the fixing plate 41. The adjusting rod 52 is a screw. When the fixing plate 41 is placed into the receiving groove, the screw passes through the receiving plate 51 and locks with the fixing plate 41. The screw has a rotating head. The position of the screw extending into the connecting plate 5 is adjusted by rotating the head. By adjusting the screws on both sides, the position of the fixing plate 41 is horizontally fine-tuned so that the position of the lower pressure head 4 is aligned with the press-fit bushing 11. At the same time, when producing different models of products, each model of product has a different spacing. Installation can be achieved by replacing the lower pressure head 4 with different spacing. After installation, the position can be adjusted by adjusting the adjusting rod 52. Installation is convenient. At the same time, the base plate 7 has a handle, which can be used to set different receiving seats according to different product needs, and disassembly is convenient.

[0048] In some implementations, a support frame 12 is mounted on the frame 1. The top of the support frame 12 has a horizontal guard. A sensor 13 is mounted on the support frame 12. The sensor 13 is mounted on the lower side of the horizontal guard and fixed by screws. It is positioned towards the receiving seat 2. The sensor 13 can be a laser sensor and is used to detect the placement position of the bushing 11.

[0049] Furthermore, a second sensor 14 is provided at the bottom of the receiving base 2 to sense whether the product is in place. A through hole is provided in the middle of the receiving base 2, and the second sensor 14 is installed on the lower side of the through hole. The second sensor 14 can be a capacitive proximity sensor to sense whether the product is placed in place. If the product is not placed in place, the pressing device will not press down.

[0050] Furthermore, the pressing assembly also includes a mounting plate 6, which is fixedly mounted to the frame 1 with a support column. A driving component 62 is provided on the mounting plate 6, which can be a cylinder. The output end of the driving component 62 is connected to the connecting plate 5, driving the connecting plate 5 to move up and down. The connecting plate 5 and the mounting plate 6 are connected by a guide shaft 61, the bottom of which is fixedly mounted to the connecting plate 5. Guide sleeves are provided at the four corners of the mounting plate 6, which slide up and down along the guide sleeves via the guide shaft 61.

[0051] In operation, firstly, install the corresponding fixing plate 41 according to the processing requirements, and adjust its left and right positions using the adjusting rod 52. Then, place the fuel tank isolation valve to be processed on the receiving seat 2 and position it using the positioning column 3. Next, place the two bushings 11 in the position to be pressed, and fit them onto the cylindrical head 31 at the top of the positioning column 3. At this time, both sensor 13 and sensor 2 14 detect the position of the product and the bushings 11. Then, the pressing assembly presses down, and the pressing head 4 descends. The pressing head 4 can also be manually controlled by a button to press the bushings 11 into place. After pressing, remove the completed bushing and insert the new one to continue processing. Pressing two bushings 11 simultaneously at one time ensures the pressing effect and improves pressing efficiency.

[0052] 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.
