[0031] Compared with the prior art, the embodiment of the present invention has the following advantages and beneficial effects:

[0032] 1. The embodiment of the present invention provides a riveting tooling for a housing - positioned rectangular connector. By placing the housing - positioned rectangular connector product to be riveted in the product placement space between the connecting plate and the upper support platform, ensuring that the rivet position of the product is aligned with the alignment holes on the upper support platform, starting the hydraulic mechanism, the hydraulic cylinder expands and contracts, pushing the pressing head part downward. The lower end of the pressing head part applies pressure to the rivet to complete the riveting operation.

In the embodiment of the present invention, through the movably - mounted pressing head part, it can be quickly replaced and adjusted according to the rivet shapes and sizes of different connector products, solving the problem in the prior art that the single - threaded hole shape cannot meet the precise connection requirements of imported equipment.

[0033] 2. In the embodiment of the present invention, by setting the bottom of the pressing head part as a planar shape or a convex arc shape, the product can be initially riveted with a pressing head part having a convex arc - shaped bottom, and then replaced with a pressing head part having a planar bottom for further riveting. This can better control the deformation process of the rivet. Because the convex arc - shaped pressing head part can better guide the metal flow during the initial riveting, avoiding stress concentration, and the planar - shaped pressing head part can ensure the tight fit between the rivet head and the connecting part during further riveting, thereby improving the connection strength. This structure and riveting method can adapt to rivets of different shapes and sizes, meeting the diverse requirements of imported equipment and precision instruments.

[0034] 3. In the embodiment of the present invention, by setting a protective sleeve in the alignment holes, the alignment holes can be protected, effectively reducing the wear of the alignment holes and extending the service life of the tooling. At the same time, through the guiding function of the protective sleeve, the pressing head part can act on the rivet more precisely, reducing the error during the riveting process. The protective sleeve can be replaced according to different riveting requirements, improving the flexibility and versatility of the tooling and better meeting the diverse requirements of imported equipment and precision instruments.

[0035] 4. The upper region provided in the embodiment of the present invention is located between the upper support platform and the lower support platform, and is used to place the upper part of the product to ensure the alignment of the rivet and the pressing head part. The lower region is located between the lower support platform and the bottom of the connecting plate and is used to place the lower part of the product. The lower support platform can be adjusted according to the shape of the product and can adapt to a variety of connector products of different sizes and shapes. By dividing the product placement space into an upper region and a lower region, in the upper region, the upper support platform and the lower support platform can clamp the upper part of the product, which can better fix the product and ensure that it does not shake or shift during the riveting process. The combined design of the lower support platform and the support feet provides double - layer support for the product, ensuring the stability of the product during the riveting process.

[0036] 5. The hydraulic mechanism provided by the embodiment of the present invention can limit the riveting mechanism on the lower hydraulic table by setting an installation groove, ensuring its stability during the riveting process. The upper hydraulic table ensures that the pressing head can accurately act on the rivets on the product. During the operation, the hydraulic driving member is started to push the lower hydraulic table to move vertically upward along the connecting rod member. As the lower hydraulic table moves, the riveting mechanism gradually approaches the upper hydraulic table, and the pressing head begins to apply pressure to the rivets on the product. The hydraulic pressure gauge displays the pressure of the pressing head on the rivets in real time, and the operator can adjust the output pressure of the hydraulic driving member as needed to ensure the stability and quality of the riveting process.

[0051] Embodiment

[0052] Embodiment 1:

[0053] As Figure 1As shown in the figure, an embodiment of the present invention provides a riveting tool for a housing-positioning rectangular connector, which includes a riveting mechanism and a hydraulic mechanism. The riveting mechanism includes a connecting plate 1 and a horizontally arranged upper support platform 2. The upper support platform 2 is vertically connected to the connecting plate 1, and there is a product placement space between the bottom of the upper support platform 2 and the horizontal plane where the bottom of the connecting plate 1 is located. A number of alignment holes 3 are provided on the upper support platform 2. A pressing head member 4 is movably arranged in a single alignment hole 3. After passing through the alignment hole 3, the pressing head member 4 can abut against a rivet 5 on the product in the product placement space. The hydraulic mechanism is configured to apply a downward pressure to the pressing head member 4, so that the lower end of the pressing head member 4 presses the rivet 5 on the product for riveting.

[0054] Specifically, the connecting plate 1 plays a role in bearing and fixing the upper support platform 2, providing a stable structural foundation for the entire riveting process, ensuring the accuracy and stability of the riveting operation. The upper support platform 2 is vertically connected to the connecting plate 1 to form a "T" - shaped structure. There is a certain space between the bottom of the connecting plate 1 and the horizontal plane where the bottom of the upper support platform 2 is located, which is used to place the connector product to be riveted. The function of the upper support platform 2 is to bear the pressing head member 4 and provide precise positioning and guidance for the pressing head member 4 through the alignment holes 3 on it. The alignment holes 3 are provided on the upper support platform 2 for movably installing the pressing head member 4. The number and layout of the alignment holes 3 can be designed according to the distribution of the rivets 5 of the connector product, ensuring that each rivet 5 can be accurately positioned and riveted by the corresponding pressing head member 4, realizing the simultaneous riveting of multiple rivets 5.

[0055] The pressing head member 4 is movably arranged in the alignment hole 3 and can abut against the rivet 5 on the connector product in the product placement space after passing through the alignment hole 3. The hydraulic mechanism provides a downward pressure for the pressing head member 4, which is the power source of the riveting operation. The hydraulic mechanism ensures the stability and consistency of the riveting process by precisely controlling the magnitude and application speed of the pressure, guaranteeing the uniform distribution of the pressure, thereby improving the riveting quality.

[0056] During use, place the housing - positioning rectangular connector product to be riveted in the product placement space between the connecting plate 1 and the upper support platform 2, ensuring that the position of the rivet 5 on the product is aligned with the alignment holes 3 on the upper support platform 2. According to the shape and size of the rivet 5 of the connector product, select a suitable pressing head member 4 and install it into the alignment hole 3. After the pressing head member 4 passes through the alignment hole 3, its lower end abuts against the rivet 5 on the connector product. Start the hydraulic mechanism, the hydraulic cylinder expands and contracts, pushing the pressing head member 4 to move upward. The hydraulic mechanism precisely controls the magnitude and application speed of the pressure to ensure that the pressing head member 4 can uniformly apply pressure to the rivet 5. After the riveting is completed, operate the hydraulic mechanism to retract, the pressing head member 4 returns to the initial position, and take out the riveted connector product.

[0057] In the embodiment of the present invention, after riveting is completed, the hydraulic mechanism retracts, and the pressing head member 4 returns to its initial position. The riveted connector product is taken out. By the movably installed pressing head member 4, it can be quickly replaced and adjusted according to the shapes and sizes of the rivets 5 of different connector products, solving the problem in the prior art that the single threaded hole shape cannot meet the precise connection of imported equipment. The hydraulic mechanism can provide stable and uniform pressure, ensuring that the rivets 5 are evenly stressed during the riveting process, avoiding deformation or damage of the rivets 5, improving the riveting quality. The structural design of the connecting plate and the upper support platform 2 provides stable support for the riveting process, ensuring the accuracy and stability of the riveting operation, and is applicable to the high-precision connector riveting requirements.

[0058] Further, as Figure 2 and Figure 3 shown, a protective sleeve 6 is movably arranged in a single alignment hole 3, and a limiting member is arranged at the bottom of the single alignment hole 3. When the protective sleeve 6 abuts against the limiting member, the limiting member can limit the protective sleeve 6 from disengaging from the alignment hole 3, and the pressing head member 4 penetrates through the protective sleeve 6. The function of the protective sleeve 6 is to protect the alignment hole 3 from possible wear, scratches or deformation during the riveting process, which can extend the service life of the alignment hole 3, reduce the accuracy decline caused by wear, and can be customized according to the shape and size of the rivet 5 specifically, providing better adaptability and ensuring the stability and accuracy of the riveting process. The limiting member ensures that the protective sleeve 6 always remains stable during the riveting process and will not shift or fall off due to external forces. It should be noted that the specific structure of the limiting member is not limited here, and only existing baffle structures, the matching structures of protrusions and grooves, etc. can be used to achieve it. It should be noted that the material of the protective sleeve 6 is not limited here, as long as it can achieve sufficient protection strength. In the embodiment of the present invention, the protective sleeve 6 can be set as a copper material.

[0059] As a preferred embodiment of the present invention, it can be set that when the protective sleeve 6 abuts against the limiting member, the top of the protective sleeve 6 is higher than the top of the alignment hole 3, and the bottom of the pressing head member 4 is flat or outwardly convex arc-shaped. Specifically, setting the protective sleeve 6 as a higher structure can facilitate the disassembly, replacement, maintenance and repair of the protective sleeve 6, etc. At the same time, in the embodiment of the present invention, by replacing the pressing head member 4 with different shapes, staged riveting can be realized, optimizing the deformation process of the rivet 5 and ensuring the riveting quality. Exemplarily, the product can be initially riveted with a pressing head member 4 with an outwardly convex arc-shaped bottom first, and then the pressing head member 4 with a flat bottom is replaced for further riveting, which can better control the deformation process of the rivet 5. Because the outwardly convex arc-shaped pressing head member 4 can better guide the metal flow during the initial riveting, avoiding stress concentration, and the flat pressing head member 4 can ensure the tight fit between the head of the rivet 5 and the connecting member during the further riveting, thereby improving the connection strength. It should be noted that the outwardly convex arc is preferably a hemispherical shape. Of course, in other embodiments, it can also be a one-third spherical shape, a two-thirds spherical shape, etc.

[0060] In order to further improve the limiting stability of the riveting mechanism for the connector, the riveting mechanism can also be set to further include a horizontally arranged lower support platform 9, which is perpendicularly connected to the connecting plate 1, and the bottom of the lower support platform 9 is higher than the bottom of the connecting plate 1. Support feet 10 are respectively arranged on both sides of the lower support platform 9, and the bottom of the support feet 10 is flush with the bottom of the connecting plate 1. The product placement space includes an upper area and a lower area. The upper area is located between the upper support platform 2 and the lower support platform 9, and the lower area is located between the lower support platform 9 and the horizontal plane where the bottom of the connecting plate 1 is located. Specifically, as Figure 3 shown, the upper area is located between the upper support platform 2 and the lower support platform 9 and is used to place the upper part 7 of the product to ensure that the rivet 5 is aligned with the pressing head part 4. The lower area is located between the lower support platform 9 and the bottom of the connecting plate 1 and is used to place the lower part 8 of the product. The lower support platform 9 can be adjusted according to the shape of the product and can adapt to various connector products with different sizes and shapes. By dividing the product placement space into an upper area and a lower area, the upper support platform 2 and the lower support platform 9 in the upper area can clamp the upper part 7 of the product, so that the product can be better fixed and ensure that it does not shake or shift during the riveting process. The combined design of the lower support platform 9 and the support feet 10 provides double-layer support for the product and ensures the stability of the product during the riveting process.

[0061] Preferably, a number of sinking holes 11 are arranged on the lower support platform 9. Each single sinking hole 11 is in the same vertical direction as each single alignment hole 3. The function of the sinking holes 11 is to provide additional positioning and supporting functions during the riveting process to ensure that the position of the rivet 5 remains constant during the riveting process. The large hole diameter, small hole diameter and depth of the sinking holes 11 can be customized according to the size of the rivet 5 and the riveting requirements. The cooperation between the sinking holes 11 and the alignment holes 3 ensures the precise alignment of the rivet 5 and the pressing head part 4 during the riveting process, prevents the rivet 5 from slipping during the riveting process, and improves the stability of the tooling.

[0062] Exemplarily, the upper support platform 2 includes a left upper platform 12, a middle upper platform 13 and a right upper platform 14 which are arranged at intervals in sequence. The lower support platform 9 includes a left lower platform 15, a middle lower platform 16 and a right lower platform 17 which are arranged at intervals in sequence. The left lower platform 15 is located directly below the upper support platform 2, the middle lower platform 16 is located directly below the middle upper platform 13, and the right lower platform 17 is located directly below the right upper platform 14. One alignment hole 3 is arranged on the left upper platform 12, and one sinking hole 11 is arranged on the left lower platform 15. One alignment hole 3 is respectively arranged at both ends of the middle upper platform 13, and one sinking hole 11 is respectively arranged at both ends of the middle lower platform 16. One alignment hole 3 is arranged on the right upper platform 14, and one sinking hole 11 is arranged on the right lower platform 17.

[0063] In the embodiments of the present invention, by dividing the upper support platform 2 and the lower support platform 9 into multiple partitions and arranging alignment holes 3 and sinking holes 11 in each partition, multiple riveting points of a product or the riveting points of multiple products can be riveted simultaneously, improving the riveting efficiency of the riveting tooling. At the same time, the installation and disassembly efficiency of the product can also be improved. Exemplarily, Figure 4 is a schematic diagram of the product splitting structure provided by the embodiments of the present invention, Figure 5 is a schematic diagram of the state structure of the product after riveting provided by the embodiments of the present invention. The product includes a first component 28, a second component 29, and a third component 30. It is necessary to connect the first component 28 and the second component 29, and the second component 29 and the third component 30 by means of riveting. Figure 3 is a state structure diagram of riveting the first component 28 and the second component 29. There are two riveting points, and the two riveting points can be operated simultaneously. After the first component 28 and the second component 29 are riveted, the product is taken off, and the product is flipped and reinstalled in the riveting mechanism to rivet the second component 29 and the third component 30 in the same way. There are also two riveting points for the second component 29 and the third component 30, and both can be riveted simultaneously.

[0064] It should be noted that in other embodiments, the structure of the product is not limited to Figure 4 and Figure 5 structures, and the shape of the riveting mechanism can also be adjusted according to the shape of the product. The number of products accommodated by the riveting mechanism at one time is not limited either, and can be specifically set according to actual needs.

[0065] Furthermore, as Figure 6 shown, the hydraulic mechanism of the embodiments of the present invention includes a connecting rod member 18, an upper hydraulic platform 19, an upper hydraulic platform 20, a hydraulic driving member 21, and a hydraulic pressure gauge 22. The upper hydraulic platform 19 is fixedly arranged at the upper end of the connecting rod member 18. The upper hydraulic platform 20 is sleeved on the connecting rod member 18. The hydraulic driving member 21 is arranged to drive the upper hydraulic platform 20 to move vertically along the connecting rod member 18. The upper hydraulic platform 20 is located below the upper hydraulic platform 19. An installation groove 23 for installing the riveting mechanism is provided at the top of the upper hydraulic platform 20. The installation groove 23 is used to limit the displacement of the riveting mechanism. The hydraulic driving member 21 can drive the riveting mechanism on the upper hydraulic platform 20 to move away from or close to the upper hydraulic platform 19. The hydraulic pressure gauge 22 is arranged to display the pressure of the pressing head member 4 on the product rivet 5.

[0066] Specifically, the connecting rod member 18 is used to connect the upper hydraulic platform 19 and the upper hydraulic platform 20, and at the same time provide stable guidance for the vertical movement of the upper hydraulic platform 20 to ensure the accuracy and stability of the movement. The upper hydraulic platform 19 is fixedly arranged at the upper end of the connecting rod member 18 and serves as the fixed part of the hydraulic mechanism. The upper hydraulic platform 19 ensures that the pressing head member 4 can accurately act on the rivet 5 on the product. The upper hydraulic platform 20 is sleeved on the connecting rod member 18 and is located below the upper hydraulic platform 19 and can move vertically along the connecting rod member 18. An installation groove 23 is provided at the top of the upper hydraulic platform 20 for installing the riveting mechanism and restricting the displacement of the riveting mechanism to ensure its stability during the riveting process. The hydraulic driving member 21 is the power source of the hydraulic mechanism and is used to drive the upper hydraulic platform 20 to move vertically along the connecting rod member 18, and can accurately control the moving speed and stroke of the upper hydraulic platform 20, thereby realizing the precise driving of the riveting mechanism. The hydraulic driving member 21 can drive the riveting mechanism on the upper hydraulic platform 20 to move away from or close to the upper hydraulic platform 19 to complete the riveting action. The hydraulic pressure gauge 22 is used to display the pressure of the pressing head member 4 on the product rivet 5 in real time. Through the hydraulic pressure gauge 22, the operator can intuitively monitor the pressure change during the riveting process to ensure the accuracy and consistency of the riveting pressure.

[0067] During the use process, the hydraulic driving member 21 is started to push the upper hydraulic platform 20 to move vertically upward along the connecting rod member 18. As the upper hydraulic platform 20 moves, the riveting mechanism gradually approaches the upper hydraulic platform 19, and the pressing head member 4 begins to apply pressure to the rivet 5 on the product. The hydraulic pressure gauge 22 displays the pressure of the pressing head member 4 on the rivet 5 in real time. The operator can adjust the output pressure of the hydraulic driving member 21 according to needs to ensure the stability and quality of the riveting process. When the riveting is completed, the hydraulic driving member 21 drives the upper hydraulic platform 20 to move downward in the reverse direction to make the riveting mechanism move away from the upper hydraulic platform 19, completing one riveting operation.

[0068] Exemplarily, the connecting rod member 18 includes a vertically arranged first connecting rod 24 and a second connecting rod 25. The hydraulic mechanism further includes a support placement platform 27. The bottom parts of the first connecting rod 24 and the second connecting rod 25 are respectively installed on both sides of the support placement platform 27. Two through holes are respectively provided at both ends of the upper hydraulic platform 19 and the upper hydraulic platform 20. The through holes at both ends of the upper hydraulic platform 19 are respectively sleeved on the first connecting rod 24 and the second connecting rod 25, and bolts 26 are respectively arranged on the first connecting rod 24 and the second connecting rod 25 to fix the upper hydraulic platform 19. The through holes on both sides of the upper hydraulic platform 20 are respectively sleeved on the first connecting rod 24 and the second connecting rod 25. The hydraulic driving member 21 is installed on the support placement platform 27 and is located between the first connecting rod 24 and the second connecting rod 25. The driving rod of the hydraulic driving member 21 abuts against the bottom of the upper hydraulic platform 20.

[0069] In the embodiment of the present invention, the double-link design provides more stable support and guiding functions. The bottoms of the first link 24 and the second link 25 are respectively installed on both sides of the support placement table 27 to ensure the stability of the entire hydraulic mechanism. The support placement table 27 is used to install and support the first link 24 and the second link 25, and at the same time provides an installation position for the hydraulic driving member 21. The support placement table 27 enhances the structural stability of the entire hydraulic mechanism and reduces the shaking caused by external forces. Two through holes are respectively provided at both ends of the upper hydraulic table 19 and the upper hydraulic table 20 for sleeving on the first link 24 and the second link 25 to ensure the stable movement of the upper hydraulic table 19 and the upper hydraulic table 20 in the vertical direction and reduce the lateral shaking at the same time. Bolts 26 are respectively provided on the first link 24 and the second link 25 for fixing the upper hydraulic table 19 on the link to ensure the stability of the upper hydraulic table 19 during the riveting process and facilitate installation and disassembly. The hydraulic driving member 21 is installed on the support placement table 27 and is located between the first link 24 and the second link 25, so that the hydraulic driving member 21 can efficiently drive the upper hydraulic table 20 to move vertically along the link. The driving rod of the hydraulic driving member 21 abuts against the bottom of the upper hydraulic table 20. Through the telescopic movement of the hydraulic driving member 21, the upper hydraulic table 20 is pushed to move vertically along the link, ensuring the precise movement of the upper hydraulic table 20 and thus realizing the precise control of the riveting mechanism.

[0070] It should be noted that the structure of the hydraulic driving member 21 can be realized by using the existing technology and is not limited here. An automatically controlled hydraulic driving structure can be adopted, or a manual driving structure can be adopted, as long as it can provide sufficient driving power for the upper hydraulic table 20. Of course, in other embodiments, a hydraulic driving structure may not be adopted, and a driving structure such as a motor can also be adopted. In the embodiment of the present invention, for the convenience of understanding, the hydraulic driving member 21 adopts a manual driving structure. When it is necessary to remove the product, only need to turn the handle and manually open the pressure relief valve, and the upper hydraulic table 20 will move downward due to its own gravity to move away from the upper hydraulic table 19, and the product can be taken out smoothly.

[0071] Embodiment 2:

[0072] The embodiment of the present invention provides a method for riveting a housing-positioned rectangular connector, which uses the housing-positioned rectangular connector riveting tooling of Embodiment 1 and specifically includes the following steps:

[0073] 1. Place the housing-positioned rectangular electrical connector into the riveting mechanism with the rivet 5 facing upward to ensure that the rivet 5 faces upward, which is convenient for the subsequent precise alignment and riveting operation of the pressing head member 4;

[0074] 2. Place the convex arc-shaped pressing head part 4 into the alignment hole 3. The convex arc-shaped pressing head part 4 can better guide the deformation of the rivet 5 during the preliminary riveting stage, reduce stress concentration, and avoid excessive deformation of the head of the rivet 5.

[0075] 3. Place the riveting mechanism for the oil-filled product on the upper hydraulic table 20. The installation groove 23 restricts the displacement of the riveting mechanism to ensure its stability during the riveting process.

[0076] 4. Raise the upper hydraulic table 20. After reaching the pressure value, press and hold it statically. Open the pressure relief valve, and take out the convex arc-shaped pressing head part 4. The convex arc-shaped pressing head part 4 performs preliminary forming on the rivet 5, causing the head of the rivet 5 to be preliminarily deformed.

[0077] 5. Place the flat-shaped pressing head part 4 into the alignment hole 3 of the riveting mechanism. After completing the preliminary riveting, replace the pressing head part 4 to perform further riveting.

[0078] 6. Then raise the upper hydraulic table 20. After reaching the pressure value, press and hold it statically. Open the pressure relief valve, and remove the product. The flat-shaped pressing head part 4 is used for further riveting to ensure the tight fit between the head of the rivet 5 and the connector housing; the entire process completes the final forming of the rivet 5, ensuring the tight fit between the head of the rivet 5 and the connector housing. After completing the riveting operation, take out the product for subsequent inspection or assembly.

[0079] In the embodiment of the present invention, the riveting process is divided into two stages, using the convex arc-shaped pressing head part 4 and the flat-shaped pressing head part 4 respectively to optimize the deformation process of the rivet 5.

[0080] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention. It should be noted that the structures or components illustrated in the drawings are not necessarily drawn to scale, and the present invention omits the description of well-known components and processing technologies and processes to avoid unnecessarily limiting the present invention.
