Description

Technical Field

[0001] This utility model relates to the field of overflow valve processing technology, and in particular to a novel overflow valve riveting device for CDC vibration dampers. Background Technology

[0002] Electronically controlled suspension systems, as a significant innovation in automotive engineering, have been widely adopted in mainstream models. However, it must be acknowledged that traditional air springs, while optimizing comfort, inevitably compromise vehicle handling stability during motion. Against this backdrop of technical contradiction, the overflow valve assembly in continuously damped controlled (CDC) shock absorbers has become a key breakthrough point. Its precision assembly process directly affects the damping adjustment accuracy and system response speed, making it a core technological element ensuring the dynamic performance of the shock absorber.

[0003] For example, the riveting equipment for the overflow valve of a CDC vibration damper, as disclosed in the public announcement (CN210139171 U), describes in its technical solution that "it includes a control cabinet and a bracket fixed on its top surface, as well as a hydraulic cylinder fixed on the top of the bracket, and also includes a riveting device installed on the top surface of the control cabinet. The riveting device includes an upper die and a lower die. By sequentially placing the overflow valve components on the valve seat fixing column, installing the sealing ring, fixing the overflow valve sleeve at the spring seat, starting the hydraulic cylinder, the upper valve sleeve is pushed downward, the riveting column and the riveting lock tongue contact each other, pushing the riveting lock tongue to move inward, and riveting the outer sleeve inward."

[0004] In summary, the existing technology suffers from the following technical problems: After prolonged high-load operation, key components of the riveting equipment exhibit the following issues: the mating surfaces of the upper and lower dies experience progressive wear due to continuous friction. This mechanical wear leads to positioning deviations when the upper die closes, directly affecting the precision control of the riveting operation. Furthermore, the existing workflow suffers from process interruptions, requiring manual removal of the finished product after each riveting operation. This discontinuous operation mode causes equipment to idle, significantly reducing overall production efficiency. Therefore, we propose a novel overflow valve riveting device for CDC vibration dampers. Utility Model Content

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0026] Example 1

[0027] Reference Figure 1-3 A novel overflow valve riveting device for CDC vibration dampers includes a frame 1 and a riveting platform 2. The riveting platform 2 is fixed to the inner side of the frame 1. An auxiliary mechanism is assembled between the frame 1 and the riveting platform 2. The auxiliary mechanism includes a hydraulic rod 3, a positioning plate 4, auxiliary columns 8, and a riveting assembly. The top of the frame 1 is fixed with the hydraulic rod 3. The output end of the hydraulic rod 3 is fixed with the positioning plate 4. The four corners of the positioning plate 4 are slidably connected with auxiliary columns 8. The auxiliary columns 8 are all fixed to the riveting platform 2. The bottom of the output end of the hydraulic rod 3 is equipped with a riveting assembly.

[0028] The riveting assembly includes an upper mold 5, a lower mold 6, and a riveting device 7. The upper mold 5 is fixed to the bottom of the output end of the hydraulic rod 3, and the lower mold 6, corresponding to the position of the upper mold 5, is fixed to the top of the riveting platform 2. The riveting device 7 is set on the top of the upper mold 5. The working principle of the riveting device 7 is common and has been disclosed in the prior art. It is a conventional method or common knowledge and will not be described in detail here. Those skilled in the art can make any selection according to their needs or convenience.

[0029] A mating mechanism is installed between the positioning plate 4 and the riveting platform 2. The mating mechanism is used to assist in the transmission of the overflow valve after riveting.

[0030] The cooperating mechanism includes an L-shaped fixing frame 9, a force-applying rod 10, a radius-angled bent rod 11, an anti-detachment block 12, a pusher rod 13, a bearing arm 14, an inclined guide rail 15, and a pusher plate 16. An L-shaped fixing frame 9 is fixed to one end of the top of the riveting platform 2. A force-applying rod 10 is fixed to the bottom of the positioning plate 4. A radius-angled bent rod 11 is fixed to the bottom of the force-applying rod 10. An anti-detachment block 12 is fixed to one end of the radius-angled bent rod 11, and the anti-detachment block 12 is slidably connected to the L-shaped fixing frame 9. The other end of the radius-angled bent rod 11 is slidably connected to a pusher plate. The push rod 13 has a sliding connection at one end to an inclined guide rail 15. The top of the inclined guide rail 15 is inclined away from the anti-detachment block 12. A bearing arm 14 is fixed on one side of the inclined guide rail 15. The bearing arm 14 is fixed to the L-shaped fixing frame 9. The other end of the push rod 13 is equipped with a push plate 16. The push plate 16 corresponds to the top position of the riveting equipment 7. When in the initial position, the upper mold 5 is in the ready-to-operate state, and the push plate 16 is located near the vertical extension line of the top of the discharge inclined table 18.

[0031] The cooperating mechanism also includes an extension rod 17. The end of the push rod 13 away from the inclined guide rail 15 is slidably connected to the extension rod 17. The extension rod 17 is fixed to the push plate 16. A bolt is threaded on one side of the push rod 13. The push rod 13 is tightly fitted to the extension rod 17 through the bolt. By loosening the screw, the extension rod 17 can be moved and adjusted inside the push rod 13, which facilitates the adjustment of the position of the push plate 16 to adapt to different specifications of the upper mold 5 and lower mold 6. Ultimately, through adjustment, the side of the push plate 16 and the side of the lower mold 6 can always be vertically aligned, preventing the push plate 16 from interfering with the vertical movement of the upper mold 5 when the upper mold 5 and lower mold 6 are closed.

[0032] A discharge ramp 18 is fixed on the inner side of the riveting platform 2. A conveyor belt 19 is provided at the bottom of the discharge ramp 18. The conveyor belt 19 facilitates the conveying of the overflow valve after riveting.

[0033] Example 2

[0034] Further optimizations to Example 1, specifically, such as... Figure 4As shown, an adjustment mechanism is assembled between the frame 1 and the hydraulic rod 3. The adjustment mechanism includes a motor 20, a lead screw 21, a movable frame 22, and a vertical rod 23. A mounting bracket is fixed at the top of the frame 1, offset from the hydraulic rod 3. The motor 20 is fixed at the top of the mounting bracket. The top and bottom of the inner side of the mounting bracket are rotatably connected to the lead screw 21. The output end of the motor 20 passes through the mounting bracket and is fixed to the lead screw 21. The outer side of the lead screw 21 is threadedly connected to the movable frame 22. The inner side of the movable frame 22 is fixed to the hydraulic rod 3. Vertical rods 23 are slidably connected to both ends of the movable frame 22. Both ends are fixed to the mounting bracket. When the bottom of the upper mold 5 is worn, the height of the upper mold 5 needs to be lowered in order to close it better with the lower mold 6. When the bottom of the upper mold 5 is worn to a certain extent, the motor 20 is started, so that the output end of the motor 20 drives the lead screw 21 to rotate, which in turn causes the movable frame 22 to drive the hydraulic rod 3 to move downward along the vertical rod 23. This allows the upper mold 5 to be adjusted to a suitable height without changing the original set stroke of the hydraulic rod 3, so that the distance between the upper mold 5 and the lower mold 6 remains consistent and to prevent positioning deviation when the upper mold 5 is closed.

[0035] In summary:

[0036] This utility model addresses the following technical problem: After prolonged high-load operation, key components of existing riveting equipment exhibit the following issues: the mating surfaces of the upper and lower dies experience progressive wear due to continuous friction. This mechanical wear leads to positioning deviations when the upper die closes, directly affecting the precision control of the riveting operation. Furthermore, the existing workflow suffers from process interruptions, requiring manual removal of the finished product after each riveting operation. This discontinuous operation mode causes equipment to idle, significantly reducing overall production efficiency. The present invention employs the technical solutions described in the above embodiments. The implementation process of the above technical solutions is as follows:

[0037] Move the device to the designated area, then connect it to an external power source. Place the overflow valve assembly to be riveted on the riveting equipment 7. Then start the hydraulic rod 3 and the conveyor belt 19. The output end of the hydraulic rod 3 pushes the positioning plate 4 and the upper mold 5 downward. At the same time, the positioning plate 4 pushes the R-angle bent rod 11 downward through the force rod 10. Because the R-angle bent rod 11 is slidably connected to the push rod 13, one end of the push rod 13 is slidably connected to the inner side of the inclined guide rail 15, and the push rod 13 is fixed to the push plate 16 through the extension rod 17, the push plate 16 can move from the riveting equipment 7 toward the R-angle bent rod 11 during the descent of the positioning plate 4, so that the upper mold 5 and the lower mold 6 close. The overflow valve assembly is riveted by the riveting equipment 7.

[0038] After riveting is completed, the output end of the control hydraulic rod 3 retracts and resets, while the upper mold 5 gradually moves upward, and the R-angle bent rod 11 pulls the push rod 13 upward. Under the guidance of the inclined guide rail 15, the push rod 13 pushes the extension rod 17 and the push plate 16 until the push plate 16 pushes the overflow valve on the riveting equipment 7 onto the discharge inclined platform 18. Under the guidance of the discharge inclined platform 18, the material is transported and conveyed through the conveyor belt 19.

[0039] With the above-mentioned settings, this application will certainly solve the above-mentioned technical problems, and at the same time achieve the following technical effects:

[0040] 1. Through the structural design of the auxiliary mechanism and the cooperating mechanism, this utility model makes it easy to push the overflow valve after riveting onto the discharge ramp 18 during the separation of the upper mold 5 and the lower mold 6 after each riveting is completed. This eliminates the need for manual removal of the finished product, enables continuous riveting operations, prevents equipment from running idle and waiting, and significantly improves overall production efficiency.

[0041] 2. Through the structural design of the adjustment mechanism, this utility model enables the device to adjust the height of the hydraulic rod 3 as a whole when the upper mold 5 is worn in the later stage, thereby adjusting the distance between the upper mold 5 and the lower mold 6, which is beneficial to use.
