Description

Technical Field

[0001] This utility model relates to the field of riveting technology, and more specifically, to a riveting device for the housing of an automotive connector. Background Technology

[0002] In the automotive manufacturing industry, connectors are crucial components ensuring the stable operation of the vehicle's electrical system, and their production quality directly impacts the vehicle's safety and reliability. To ensure a secure connection between the connector housings, a housing riveting process is typically employed. The riveting plate in the riveting device, as a key actuator, is responsible for precisely pressing the connector housings together, ensuring a strong and dimensionally consistent connection. However, in existing technologies, the installation and removal of the riveting plate present significant inconveniences, severely impacting production efficiency and equipment adaptability.

[0003] Existing riveting plates are mostly fixed using bolts, clips, or interference fits. Installation and disassembly are cumbersome, requiring specialized tools and are time-consuming.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, the present invention provides a riveting device for the housing of an automotive connector, which has the following advantages:

[0017] This utility model features a pressure plate mounting mechanism. Through the coordinated design of the riveting plate, longitudinal screw assembly, support plate, and locking rod, the pressure plate mounting mechanism enables rapid connection and separation between the riveting plate and the support structure. This allows the riveting plate to stably withstand riveting pressure, improving riveting accuracy. It also facilitates the replacement of riveting plates of different specifications.

[0029] Please see Figures 1-5A riveting device for the housing of an automotive connector includes a base plate 1, a pressure plate mounting mechanism, a snap-fit ​​mechanism, and a snap-fit ​​auxiliary mechanism. The pressure plate mounting mechanism includes a riveting plate 2 and a longitudinal screw assembly 3. A support plate 4 is mounted on the longitudinal screw assembly 3, and a snap-fit ​​tube 5 is mounted on the support plate 4. A mounting plate 6 is mounted on the riveting plate 2, and a snap-fit ​​rod 7 is mounted on the mounting plate 6. One end of the snap-fit ​​rod 7 can extend into the snap-fit ​​tube 5 to engage and snap-fit, connecting the support plate 4 and the mounting plate 6. The structure includes a rotating plate 8 and a longitudinal sliding sleeve 9. A slot 10 is provided on the side wall of the locking rod 7. The longitudinal sliding sleeve 9 is longitudinally slidably installed on the outer wall of the locking tube 5. The rotating plate 8 is rotatably installed on the side wall of the locking tube 5. An embedded block 11 and a pressure pry block 12 are installed at both ends of the rotating plate 8. The inner wall of the longitudinal sliding sleeve 9 can press against the rotating plate 8, so that the embedded block 11 at one end of the rotating plate 8 extends into the slot 10. The inner wall of the longitudinal sliding sleeve 9 presses against the pressure pry block 12, so that the embedded block 11 moves away from the slot 10.

[0030] In this embodiment, the pressure plate mounting mechanism achieves a quick connection between the riveting plate 2 and the support structure through the cooperation of the locking rod 7 and the locking tube 5. During the riveting process, the locking rod 7 extends into the locking tube 5 to firmly connect the support plate 4 and the mounting plate 6, ensuring that the riveting plate 2 remains stable under pressure and providing basic support for precise riveting. The locking mechanism uses the rocker principle of the rotating plate 8 to achieve locking and unlocking functions. When the longitudinal sleeve 9 moves down, the inner wall presses against the rotating plate 8, causing the embedded block 11 to extend into the slot 10 to complete the locking. When the longitudinal sleeve 9 moves up, the inner wall presses against the pry block 12, causing the embedded block 11 to move away from the slot 10 to complete the unlocking. This allows the riveting plate 2 to be firmly locked when needed and to be quickly released after riveting is completed.

[0031] The clamping auxiliary mechanism includes a screw frame 101 and a tightening block 102. The screw frame 101 is rotatably mounted on the outer wall of the clamping tube 5. The inner wall of the screw frame 101 is threadedly connected to the longitudinal sleeve 9. A turntable 13 is mounted on the top end of the screw frame 101. A fixing block 14 is fixedly mounted on the outer wall of the clamping tube 5. Multiple sets of tightening blocks 102 are slidably mounted on the turntable 13. A tightening spring 15 is installed between adjacent tightening blocks 102. The tightening blocks 102 sequentially fit the fixing blocks 14, so that the screw frame 101 rotates stably.

[0032] In this embodiment, the snap-fit ​​auxiliary mechanism controls the up-and-down movement of the longitudinal sleeve 9 by rotating the screw frame 101. When the turntable 13 is rotated, the tightening block 102 is fitted into the fixing block 14 to ensure that the screw frame 101 rotates stably. The threaded connection between the screw frame 101 and the longitudinal sleeve 9 converts the rotational motion into longitudinal motion, accurately controls the position of the longitudinal sleeve 9, thereby achieving reliable operation of the snap-fit ​​mechanism.

[0033] Please see Figures 1-5As a supplementary embodiment of a riveting device for an automotive connector housing, which includes a pressure plate mounting mechanism, a snap-fit ​​mechanism, and a snap-fit ​​auxiliary mechanism: A support column 16 is mounted on the top end of the base plate 1, and a transverse lead screw assembly 301 is mounted on the support column 16. A transverse plate 17 is mounted on the transverse lead screw assembly 301, and a longitudinal lead screw assembly 3 is mounted on the transverse plate 17. A material box 18 is mounted on the side of the base plate 1, and two sets of longitudinal lead screw assemblies 3 are provided. The material in the material box 18 can be fixed on the riveting plate 2. The top end of the turntable 13 is equipped with a module frame 19 and a positioning component 20. Multiple positioning components 20 are provided. The module frame 19 can be positioned opposite to the riveting plate 2. One end of the positioning component 20 can push against the material inside the module frame 19. The top end of the turntable 13 is equipped with a centripetal rail 21. The tightening block 102 is slidably set on the centripetal rail 21. One end of the snap-fit ​​rod 7 is equipped with a limiting block 22. The bottom end of the side wall of the snap-fit ​​pipe 5 is equipped with a connecting plate 23. The connecting plate 23 is fixedly installed on the support plate 4.

[0034] More specifically, the entire riveting process first positions the riveting plate 2 using the transverse and longitudinal screw assembly 3. Then, the material is taken out from the material box 18 and placed in the module frame 19. The positioning assembly 20 ensures accurate material positioning. After the riveting plate 2 is connected to the support structure through the snap-fit ​​system, it is pressed down under the drive of the longitudinal screw assembly 3 to perform the riveting operation. After the riveting is completed, the riveting plate 2 rises, completing one riveting cycle. The snap-fit ​​system can be unlocked or reinstalled, facilitating the replacement of different riveting plates 2. This device achieves efficient riveting of automotive connector housings through precise three-dimensional positioning and a reliable snap-fit ​​system.

[0035] In summary, during the use or operation of the overall equipment: when the pressure plate mounting mechanism is required to operate, the pressure plate mounting mechanism achieves a quick connection between the riveting pressure plate 2 and the support structure through the cooperation of the snap-fit ​​rod 7 and the snap-fit ​​tube 5. During the riveting process, the snap-fit ​​rod 7 extends into the snap-fit ​​tube 5 to firmly connect the support plate 4 and the mounting plate 6, ensuring that the riveting pressure plate 2 remains stable under pressure and providing basic support for precise riveting.

[0036] When the locking mechanism is in operation, it uses the rocker principle of the rotating plate 8 to achieve locking and unlocking functions. When the longitudinal sleeve 9 moves down, the inner wall presses against the rotating plate 8, causing the embedded block 11 to extend into the slot 10 to complete the locking. When the longitudinal sleeve 9 moves up, the inner wall presses against the pry block 12, causing the embedded block 11 to move away from the slot 10 to complete the unlocking. This allows the riveting plate 2 to be firmly locked when needed and to be quickly released after riveting is completed.

[0037] When the snap-fit ​​auxiliary mechanism is in operation, the snap-fit ​​auxiliary mechanism controls the up and down movement of the longitudinal sleeve 9 by rotating the screw frame 101. When the turntable 13 is rotated, the tightening block 102 is fitted into the fixing block 14 to ensure that the screw frame 101 rotates stably. The threaded connection between the screw frame 101 and the longitudinal sleeve 9 converts the rotational motion into longitudinal motion, accurately controls the position of the longitudinal sleeve 9, and thus realizes reliable operation of the snap-fit ​​mechanism.

[0038] The entire riveting process begins by positioning the riveting plate 2 using the transverse and longitudinal screw assembly 3. Then, the material is taken out from the material box 18 and placed in the module frame 19. The positioning assembly 20 ensures accurate material positioning. After the riveting plate 2 is connected to the support structure through the snap-fit ​​system, it is pressed down under the drive of the longitudinal screw assembly 3 to perform the riveting operation. After the riveting is completed, the riveting plate 2 rises, completing one riveting cycle. The snap-fit ​​system can be unlocked or reinstalled, facilitating the replacement of different riveting plates 2. This device achieves efficient riveting of automotive connector housings through precise three-dimensional positioning and a reliable snap-fit ​​system.
