Description

Technical Field

[0001] This utility model relates to the field of automotive parts manufacturing technology, and in particular to a cylinder self-adjustment device for a car tailgate lower trim panel removal system. Background Technology

[0002] In the manufacturing process of automotive tailgate trim panels, the straightening process is a crucial step to ensure that the product's dimensional accuracy and shape meet design requirements. However, existing cylinder pusher assembly mechanisms have the following prominent problems in practical applications:

[0003] Poor initial fit: The product's straightening surface is often sloping. Due to the limitations of the structure and assembly method of traditional cylinder pushers, the pusher usually cannot fully fit the product's straightening surface. This leads to uneven force on the product during the straightening process, with some areas failing to achieve effective straightening, thus affecting the overall quality of the product.

[0004] Dynamic fit is difficult: During the straightening process, the angle of the product's straightening surface changes. However, the existing cylinder pusher is fixedly installed and cannot automatically adjust with the change in the angle of the product's straightening surface, making it impossible for the product and the pusher to fit completely. This single-line force not only results in poor straightening effect but also easily leads to concentrated stress points, causing product damage, increasing the product defect rate, and raising production costs.

[0025] Please see Figures 1 to 4 In a first aspect, this utility model provides a cylinder self-adjusting device for a car tailgate lower trim panel removal system, including a movable frame 1, a cylinder body 2, and a bonding mechanism. The bonding mechanism includes a base frame 3, a longitudinal adjustment component, a first limiting component, a lateral adjustment component, a second limiting component 4, a rotating component, and an adjusting plate.

[0026] In this embodiment, the limiting component one and the limiting component two 4 have the same structure. The movable frame 1 provides the installation conditions for the bonding mechanism. When it is necessary to adjust the bonding angle of the cylinder body 2, the limiting component one and the limiting component two 4 are activated to release the limiting of the longitudinal adjustment component and the lateral adjustment component, respectively. The longitudinal adjustment component is activated, and the cylinder body 2 on the adjustment plate is moved on the rotating component for longitudinal adjustment. Then, the lateral adjustment component is activated, and the adjustment plate is moved on the rotating component and adjusted to the preset position. The limiting component one and the limiting component two 4 are reset, thus completing the adjustment of the bonding angle of the cylinder body 2. This solves the problem of uneven force caused by the cylinder push block not being able to fully fit with the product's orthopedic surface.

[0027] Furthermore, the longitudinal adjustment assembly includes a motor 5, a transmission shaft 6, an arc-shaped plate 7, and a rotating shaft 8. The arc-shaped plate 7 has a through groove 9. The motor 5 is fixedly connected to the base frame 3 and located on one side of the base frame 3.

[0028] In this embodiment, the operation of the motor 5 can drive the transmission shaft 6 to rotate, the rotation of the transmission shaft 6 can drive the arc plate 7 to rotate on the transmission shaft 6, and the rotation of the arc plate 7 can drive the connecting rod 20 to move within the through groove 14 for longitudinal adjustment.

[0029] Furthermore, the lateral adjustment assembly includes a second motor 10, a second transmission shaft 11, a second arc plate 12, and a second rotating shaft 13. The arc plate has a second through groove 14. The second motor 10 is fixedly connected to the base frame 3 and located on one side of the base frame 3. The second transmission shaft 11 is fixedly connected to the output end of the second motor 10 and rotatably connected to the base frame 3. The second arc plate 12 is fixedly connected to the second transmission shaft 11 and located above the first arc plate 7. The second rotating shaft 13 is fixedly connected to the second arc plate 12 and rotatably connected to the base frame 3.

[0030] In this embodiment, the operation of the second motor 10 can drive the second transmission shaft 11 to rotate. The rotation of the second transmission shaft 11 can drive the second arc plate 12 to rotate on the second transmission shaft 11. The rotation of the second arc plate 12 can drive the connecting rod 20 to move within the through groove 9 for longitudinal adjustment.

[0031] Furthermore, the rotating assembly includes a first slider 15, a rotating ball 16, and a second slider 17. The rotating ball 16 has a first groove 18 and a second groove 19. The first slider 15 is fixedly connected to the base frame 3 and is located in the first groove 18. The rotating ball 16 is slidably connected to the first slider 15 and is located on the first slider 15. The second slider 17 is slidably connected to the rotating ball 16 and is located in the second groove 19.

[0032] In this embodiment, the first slider 15 provides the installation conditions for the rotating ball 16, the rotating ball 16 provides the installation conditions for the second slider 17, the second slider 17 provides the installation conditions for the connecting rod 20. When the connecting rod 20 moves laterally, it causes the rotating ball 16 to slide on the first slider 15. When the connecting rod 20 moves longitudinally, it causes the second slider 17 to move longitudinally within the second groove 19.

[0033] Furthermore, the adjusting plate includes a connecting rod 20 and a plate body 21. The connecting rod 20 is fixedly connected to the second slider 17 and is located in the first through groove 9 and the second through groove 14. The plate body 21 is fixedly connected to the connecting rod 20 and is connected to the cylinder body 2.

[0034] In this embodiment, the connecting rod 20 can connect the plate 21 and the slider 17, and the plate 21 provides installation conditions for the cylinder body 2.

[0035] Furthermore, the limiting component includes a fixing head 22, an electric actuator 23, a connecting frame 24, a limiting block 25, and a guide rod 26. The fixing head 22 has a fixing hole 27. The fixing head 22 is fixedly connected to the rotating shaft 8 and rotatably connected to the base frame 3. The electric actuator 23 is fixedly connected to the base frame 3 and is located on one side of the base frame 3. The connecting frame 24 is fixedly connected to the output end of the electric actuator 23. The limiting block 25 is fixedly connected to the connecting frame 24 and is located in the fixing hole 27. The guide rod 26 is fixedly connected to the connecting frame 24, passes through the base frame 3, and is slidably connected to the base frame 3.

[0036] In this embodiment, the fixing head 22, in conjunction with the limiting block 25, can limit the rotation shaft 8. The operation of the electric push rod 23 can drive the connecting frame 24 to move. The movement of the connecting frame 24 can drive the limiting block 25 to move. When the connecting frame 24 moves, it drives the guide rod 26 to slide on the base frame 3. The guide rod 26 guides and limits the connecting frame 24, thereby improving the stability of the connecting frame 24 when it moves.

[0037] When it is necessary to adjust the contact angle of the cylinder body 2, the electric actuator 23 is activated to drive the connecting frame 24 to move away from the base frame 3. The connecting frame 24 drives the limiting block 25 to move away from the fixing head 22 until the fixing head 22 is completely removed from the fixing hole 27, thus releasing the restriction on the transmission shaft 6. At the same time, the limiting component releases the restriction on the rotating shaft 13, and the motor 5 is activated. The motor 5 drives the transmission shaft 6 to rotate. The drive shaft 6 drives the arc-shaped plate 7 to rotate on the rotating shaft 8. The arc-shaped plate 7 drives the connecting rod 20 to move within the through groove 14. The connecting rod 20 drives the slider 17 to slide within the sliding groove 19 on the rotating ball 16. Simultaneously, the connecting rod 20 drives the cylinder body 2 on the plate 21 to move longitudinally until the push block on the cylinder body 2 moves to a preset position. At this point, the motor 5 stops working, and the motor 10 is started. The motor 10 then begins to operate. The second transmission shaft 11 is driven to rotate, which in turn drives the second arc-shaped plate 12 to rotate on the second rotation shaft 13. The second arc-shaped plate 12, through the second slider 17 on the connecting rod 20, drives the rotating ball 16 to slide on the first slider 15, and simultaneously drives the connecting rod 20 to move within the first slide groove 18. The connecting rod 20 drives the cylinder body 2 on the plate 21 to move laterally until the push block on the cylinder body 2 moves to a preset angle, at which point the second motor 10 stops working. The electric push rod 23 drives the connecting frame 24 to move closer to the base frame 3. The connecting frame 24 drives the limiting block 25 to move closer to the fixing head 22 until the limiting block 25 moves into the fixing hole 27, limiting the rotation shaft 13. At the same time, the limiting component 4 resets to limit the rotation shaft 13, thus completing the adjustment of the fitting angle of the cylinder body 2. This solves the problem of uneven force caused by the cylinder push block not being able to fully fit with the product straightening surface.

[0038] Please see Figure 5 Secondly, a cylinder self-adjustment method for an automotive tailgate lower trim panel removal system, used in the cylinder self-adjustment device of the automotive tailgate lower trim panel removal system described in the first aspect, includes the following steps:

[0039] S1 activates limit component one and limit component two 4 to release the limits on the longitudinal adjustment component and the lateral adjustment component respectively;

[0040] Specifically, when it is necessary to adjust the contact angle of the cylinder body 2, the electric actuator 23 is activated to drive the connecting frame 24 to move away from the base frame 3. The connecting frame 24 drives the limiting block 25 to move away from the fixing head 22 until the fixing head 22 is completely removed from the fixing hole 27, thereby releasing the restriction on the transmission shaft 6. At the same time, the limiting component works to release the restriction on the rotating shaft 13.

[0041] S2 starts the longitudinal adjustment component. After the cylinder body 2 on the adjustment plate moves on the rotating component to make longitudinal adjustment, the transverse adjustment component drives the adjustment plate to move on the rotating component and adjusts it to the preset position.

[0042] Specifically, the motor 5 is started, which drives the transmission shaft 6 to rotate. The transmission shaft 6 drives the arc plate 7 to rotate on the rotating shaft 8. The arc plate 7 drives the connecting rod 20 to move within the through groove 14. The connecting rod 20 drives the slider 17 to slide within the groove 19 on the rotating ball 16. Simultaneously, the connecting rod 20 drives the cylinder body 2 on the plate 21 to move longitudinally until the push block on the cylinder body 2 moves to the preset position. The motor 5 then stops working, and the circuit is started. The second motor 10 drives the second transmission shaft 11 to rotate. The second transmission shaft 11 drives the second arc plate 12 to rotate on the second rotation shaft 13. The second arc plate 12 drives the second rotating ball 16 to slide on the first slider 15 through the second slider 17 on the connecting rod 20. At the same time, it drives the connecting rod 20 to move in the first slide groove 18. The connecting rod 20 drives the cylinder body 2 on the plate 21 to move laterally until the push block on the cylinder body 2 moves to a preset angle, and then the second motor 10 stops working.

[0043] S3 limit component one and limit component two 4 reset to complete the adjustment of the contact angle of the cylinder body 2.

[0044] Specifically, the electric actuator 23 drives the connecting frame 24 to move closer to the base frame 3. The connecting frame 24 drives the limiting block 25 to move closer to the fixing head 22 until the limiting block 25 moves into the fixing hole 27 to limit the rotation shaft 13. At the same time, the limiting component 4 resets to limit the rotation shaft 13, thus completing the adjustment of the fitting angle of the cylinder body 2.
