[0002] Riveting technology is widely used in the automation industry. For ordinary riveting, it is generally achieved by combining a moving die and a fixed die. For example, the product is placed on a fixed die and remains stationary, while the moving die applies force to the product, causing deformation and achieving the riveting effect. However, in situations where a fixed die cannot be set up, two moving dies are needed to rivet towards the center simultaneously. Although the riveting mechanisms provided in related technologies can achieve the purpose of riveting two moving dies towards the center, the riveting force is constantly changing during the riveting process, which can easily cause over-stamping of the parts to be riveted, resulting in product deformation.

[0014] As a preferred technical solution of the above-mentioned riveting mechanism, the first mounting hole penetrates through the first end face of the retainer.

[0015] As a preferred technical solution of the above-mentioned riveting mechanism, the retainer is a circular ring structure.

[0016] As a preferred technical solution of the above-mentioned riveting mechanism, the riveting head includes a working part and a moving part.

[0020] This utility model has at least the following beneficial effects:

[0021] The riveting mechanism provided by this utility model has a constant pressure arc wall that contacts the riveting assembly during the rotation of the rotating ring. This allows the riveting assembly to press the workpiece under constant pressure, meaning the pressure applied to the workpiece is constant and does not fluctuate. As a result, the riveting force on the workpiece is constant during the riveting process, preventing impact deformation. When the release wall contacts the riveting assembly, the riveting assembly releases the workpiece, facilitating the picking and placing of the workpiece.

It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0033] The present invention provides a riveting mechanism that can operate under constant pressure during the riveting process, thereby avoiding excessive impact force that could cause deformation of the parts to be riveted.

[0034] like Figures 1 to 4 As shown, the riveting mechanism includes a drive assembly 1 and at least two riveting assemblies 2. The drive assembly 1 includes a drive structure 11 and a rotating ring 12. The drive structure 11 is fixedly connected to the rotating ring 12 and can drive the rotating ring 12 to rotate. The hole wall of the rotating ring 12 includes an even number of constant pressure arc-shaped walls 121 and an even number of release walls 122. The constant pressure arc-shaped walls 121 and the release walls 122 are arranged alternately, that is, the number of constant pressure arc-shaped walls 121 and the number of release walls 122 are the same. The two ends of the constant pressure arc-shaped walls 121 are connected to different release walls 122 respectively. The distance between the constant pressure arc-shaped walls 121 and the part to be riveted 100 is less than the distance between the release walls 122 and the part to be riveted 100. The riveting assembly 2 is disposed within the area enclosed by the rotating ring 12, and part of the riveting assembly 2 is in contact with the hole wall of the rotating ring 12. The riveting assembly 2 is arranged axially symmetrically along the radial central axis of the rotating ring 12. When the rotating ring 12 is rotated, the constant pressure arc wall 121 contacts the riveting assembly 2, and the riveting assembly 2 presses the part to be riveted 100 under constant pressure. When the release wall 122 contacts the riveting assembly 2, the riveting assembly 2 releases the part to be riveted 100.

[0035] The riveting mechanism provided by this utility model, during the rotation of the rotating ring 12, the constant pressure arc wall 121 contacts the riveting assembly 2, which enables the riveting assembly 2 to press the riveted part 100 with constant pressure. That is, the pressing force on the riveted part 100 is constant and will not fluctuate. In this way, the riveting force on the riveted part 100 is constant during the riveting process, and no impact deformation will occur. When the release wall 122 contacts the riveting assembly 2, the riveting assembly 2 releases the riveted part 100, which facilitates the picking and putting away of the riveted part 100. The constant pressure arc wall 121 and the release wall 122 are arranged alternately, which enables the rotating ring 12 to press and then release the riveted part 100 during the rotation, which facilitates the picking and putting away of the riveted part 100.

[0036] In some embodiments, there are two constant-pressure arc-shaped walls 121, and correspondingly, there are also two riveting components 2, with each riveting component 2 corresponding to one of the constant-pressure arc-shaped walls 121. In other embodiments, there are four constant-pressure arc-shaped walls 121, and correspondingly, there are also four riveting components 2. The four riveting components 2 are evenly arranged along the circumference of the rotating ring 12, and the two riveting components 2 arranged opposite each other cooperate to achieve the purpose of riveting. Among them, two riveting components 2 are the main working riveting components, and the other two are used as spare riveting components to prevent downtime maintenance problems caused by damage to the main working riveting components.

[0037] Furthermore, such as Figure 3As shown, the release wall 122 is an arc-shaped wall, and the center of the release wall 122 is not overlapping with the center of the rotating ring 12. The constant pressure arc-shaped wall 121 is the hole wall of the rotating ring 12. This arrangement ensures that during the rotation of the rotating ring 12, the release wall 122 can slowly release the riveted parts that have been riveted.

[0038] In some other embodiments, the release wall 122 is a V-shaped wall, which also allows for the release of the riveted parts that have already been riveted. Furthermore, this structure ensures that once the rotating ring 12 has rotated to its position, the release wall 122 no longer applies compressive force to the riveted parts.

[0039] In some embodiments, combined with Figures 2 to 3 As shown, the riveting assembly 2 includes a rotating part 21, a restoring part 22, a retainer 23, and a riveting head 24. The rotating part 21 is connected to the riveting head 24 and can rotate relative to the riveting head 24. With this configuration, the rotating part 21 can rotate around its own axial central axis as the rotating ring 12 rotates, so that the friction between the rotating part 21 and the rotating ring 12 is rotational friction. This makes the rotation of the rotating ring 12 smoother and reduces the wear between the rotating part 21 and the rotating ring 12. The outer peripheral wall of the rotating member 21 contacts the hole wall of the rotating ring 12. The retainer 23 has a first mounting hole. The length extension direction of the first mounting hole is in the same direction as the length extension direction of the rivet head 24. The rivet head 24 is partially disposed in the first mounting hole. The part of the rivet head 24 that contacts the part to be riveted 100 is located in the area enclosed by the retainer 23. The rivet head 24 can slide along the length direction of the first mounting hole. The first mounting hole can provide support, guidance and limit for the rivet head 24, so that the rivet head 24 always moves in a straight line and avoids the rivet head 24 from being displaced. The two ends of the restorer 22 are fixedly connected to the retainer 23 and the rivet head 24 respectively. The restorer 22 is disposed outside the retainer 23. The restorer 22 can keep the hole wall of the rotating ring 12 and the outer peripheral wall of the rotating member 21 always in contact. When the release wall 122 of the rotating ring 12 rotates to the position of the rotating member 21, the restorer 22 can push the rivet head 24 to move in the direction of the rotating ring 12.

[0040] In order to secure the recovery component 22, in some embodiments, the retainer 23 is provided with a second mounting hole, and the rotating component 21 is provided with a third mounting hole. The third mounting hole is opposite to the second mounting hole, and the third mounting hole corresponds to the second mounting hole one-to-one. The two ends of the recovery component 22 are respectively fixed to the second mounting hole and the third mounting hole. The recovery component 22 always has a tendency to push the rotating component 21 away from the rivet joint 24, so as to ensure that when the release wall 122 of the rotating ring 12 rotates to the position of the rotating component 21, the rotating component 21 and the release wall 122 are always in close contact.

[0041] To make the riveting assembly 2 more compact and reduce the space occupied by the riveting assembly 2, a receiving groove is provided at the end of the riveting head 24 away from the part to be riveted 100. The rotating part 21 is rotatably disposed in the receiving groove. Part of the rotating part 21 extends out of the receiving groove and abuts against the hole wall of the rotating ring 12. That is, the transfer part is located outside the receiving groove. This arrangement can ensure that the rotating part 21 can abut against the hole wall of the rotating ring 12, and ensure that the riveting head 24 can move according to the position when the rotating ring 12 rotates.

[0042] In some embodiments, a first mounting hole extends through the first end face 231 of the retainer 23. This arrangement facilitates the machining of the first mounting hole and also facilitates the installation of the rivet 24. A retaining ring 25 is also installed on the first end face 231 of the retainer 23. The retaining ring 25 is used to cover the first mounting hole to prevent the rivet 24 from coming out of the first mounting hole during operation.

[0043] In some embodiments, the retainer 23 is a circular ring structure. The circular ring structure facilitates the arrangement of the riveting components 2, which are in even numbers. When the first mounting holes are opened, there is no need to limit the position of the retainer 23; it is sufficient that the first mounting holes are axially evenly distributed on the retainer 23. Furthermore, the circular ring structure of the retainer 23 reduces the internal space requirements of the rotating ring 12, further contributing to the compact structure of the riveting mechanism.

[0044] In some embodiments, the riveting joint 24 includes a working part 241 and a moving part 242, which are fixedly connected. For example, the working part 241 and the moving part 242 are fixedly connected by screws. A rotating member 21 and the working part 241 are respectively disposed at both ends of the moving part 242, and the rotating member 21 is rotatably connected to the working part 241. The working part 241 is located within the area formed by the retainer 23. This arrangement ensures that the working part 241 can contact the part 100 to be riveted, and that the working part 241 does not detach from the retainer 23, thus ensuring proper operation during actual work. Furthermore, the riveting joint 24 includes a working part 241 and a moving part 242, and the riveting joint 24 has a split structure, which reduces the manufacturing difficulty of the riveting joint 24.

[0045] Furthermore, the movable part 242 is provided with a T-shaped mounting groove, and the working part 241 has a T-shaped structure. The large end of the working part 241 is located in the T-shaped mounting groove, and the small end of the working part 241 extends out of the T-shaped mounting groove. The large end of the working part 241 abuts against the groove wall of the T-shaped mounting groove. The T-shaped mounting groove facilitates the installation of the working part 241 and reduces the installation height of the working part 241, thereby reducing the processing requirements of the working part 241. In addition, the T-shaped mounting groove can also be used for pre-positioning the working part 241 before connection, improving the installation efficiency and accuracy of both the movable part 242 and the working part 241.

[0046] In order to limit the rotation ring 12, combined with Figure 1 and Figure 4 The riveting mechanism also includes a frame 3, a drive assembly 1 is mounted on the frame 3, and a rotating ring 12 is rotatably mounted on the frame 3 so that the rotating ring 12 will not shift position, thus ensuring that the rotating ring 12 can rotate around its own central axis and that the riveting is carried out normally.

[0047] It should be noted that the drive component 112 is also fixed on the frame 3, and the frame 3 provides support for the drive component 112.

[0048] The frame 3 includes a support plate 31 and a bracket 32, with the support plate 31 slidably connected to the bracket 32. The riveting mechanism also includes a height adjustment component 5 and a level adjustment component. The height adjustment component 5 includes a height cylinder 51 and a first slide rail slider structure 52, while the level adjustment component includes a second slide rail slider structure 6. The support plate 31 is slidably connected to the bracket 32 ​​via the first slide rail slider structure 52, and the cylinder is fixedly connected to the support plate 31 to push or pull the support plate 31 to adjust its height.

[0049] In some embodiments, the drive structure 11 includes a swing arm 111 and a drive member 112. The two ends of the swing arm 111 are fixedly connected to the rotating ring 12 and the output end of the drive member 112, respectively. The output end of the drive member 112 is hinged to the swing arm 111. For example, the drive member 112 is a cylinder or a hydraulic cylinder. The output end of the drive member 112 moves linearly. Since the output end of the drive member 112 is hinged to the swing arm 111, the swing arm 111 can swing to rotate the rotating ring 12 during the linear movement of the drive member 112. The rotation angle is positively correlated with the stroke of the output end of the drive member 112, thereby providing power to the rotating ring 12.

[0050] More specifically, the drive structure 11 also includes a connecting frame 114, the swing arm 111 and the connecting frame 114 are rotatably connected by a pin, and the connecting frame 114 is connected to the output end of the drive component 112. The connecting frame 114 can serve as an intermediate connection.

[0051] The drive structure 11 also includes a movable plate 113, which is slidably connected to the bracket 32 ​​via a second slide rail slider structure 6. A connecting frame 114 is fixedly connected to the movable plate 113. The movable plate 113 is connected to the drive member 112. When the drive member 112 drives the movable plate 113 to move linearly, the connecting frame 114 moves along with the movable plate 113, allowing the swing arm 111 to swing. The bracket 32 ​​has clearance holes to facilitate the connection between the swing arm 111 and the movable plate 113. Placing the first slide rail slider structure 52 and the second slide rail slider structure 6 on both sides of the bracket 32 ​​improves the overall compactness of the riveting mechanism and reduces its overall volume.

[0052] The frame 3 is also provided with a limiting structure 4, which is located on both sides of the bearing plate 31, along with the cylinder, to prevent the bearing plate 31 from moving excessively.

[0053] Furthermore, the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments, and may include many other equivalent embodiments without departing from the concept of the present invention, the scope of which is determined by the scope of the appended claims.
