[0046] In manufacturing, the reliability and stability of product connection are crucial to the quality and performance of products. Among them, riveting as a common connection process is widely used in the manufacturing of various products. Riveting process is a process in which two or more parts are connected together by a riveting device through pressure, and the parts are plastically deformed by applying pressure and firmly connected together. The riveting device usually relies on axial hard connection support to resist the force during riveting, but when riveting some precision parts, the precision parts need to bear the entire riveting force, which is easy to cause damage to the precision parts and affect the quality of the precision parts.

[0047] To solve the above technical problems, as shown in Figure 1 and Figure 2 The riveting device 1 provided by the embodiment of the present application comprises a base 11, a pressing piece 12 and a riveting piece 13. The pressing piece 12 and the riveting piece 13 are both movably connected with the base 11, and the riveting piece 13 is used to connect with the workpiece to be riveted. The riveting device 1 can further comprise a connecting piece 14, which is rotatably connected with the base 11, and the connecting piece 14 is used to connect the pressing piece 12 and the riveting piece 13. When the pressing piece 12 is pressed, it can drive the connecting piece 14 to rotate to drive the riveting piece 13 to move, and the movement direction of the pressing piece 12 is perpendicular to the movement direction of the riveting piece 13.

[0048] In the embodiment, the end of the pressing piece 12 away from the base 11 is connected with an external power equipment, which is used to press the pressing piece 12 to provide driving force to realize the riveting process. By arranging the connecting piece 14 between the pressing piece 12 and the riveting piece 13, the pressing piece 12 can transmit driving force through the connecting piece 14 to drive the riveting piece 13 to move, and the connecting piece 14 can rotate to change the direction of the driving force transmitted by the pressing piece 12 through the rotation of the connecting piece 14 when the pressing piece 12 drives the riveting piece 13 to move, so that the movement direction of the riveting piece 13 is perpendicular to the movement direction of the pressing piece 12.

[0049] Compared with the direct driving of the riveting piece 13 by the pressing piece 12, the way of connecting the pressing piece 12 and the riveting piece 13 through the connecting piece 14 in the embodiment of the present application can change the direction of the driving force provided by the external power equipment through the connecting piece 14 before transmitting it to the riveting piece 13, for example, when the external power equipment transmits driving force along the axial direction of the riveting device 1 to the pressing piece 12, the driving force can be converted into driving force along the radial direction of the riveting device 1 through the connecting piece 14, and directly act on the riveting position 21 of the workpiece to be riveted 2, so that the workpiece to be riveted 2 does not need to bear the entire axial pressure brought by the external power equipment, avoiding damage to the workpiece to be riveted 2 due to excessive axial pressure, thereby improving the reliability and safety of the riveting process.

[0050] In a specific embodiment, asFigure 2 As shown, the pressing member 12, the connecting member 14 and the riveting member 13 can be distributed along the axial direction of the riveting device 1. When the pressing member 12 moves along the axial direction of the riveting device 1, the pressing member 12 drives the riveting member 13 to move along the radial direction of the riveting device 1 through the connecting member 14.

[0051] In the embodiment, the pressing member 12, the connecting member 14 and the riveting member 13 are distributed along the axial direction of the riveting device 1, that is, the connecting member 14 is located between the pressing member 12 and the riveting member 13, so that the connecting member 14 connects the pressing member 12 and the riveting member 13. When the pressing member 12 is driven by the axial driving force provided by the external power equipment, the pressing member 12 can move along the axial direction of the riveting device 1 and drive the connecting member 14 to rotate, so that the connecting member 14 can drive the riveting member 13 to move along the radial direction of the riveting device 1, and then drive the riveting member 13 to perform riveting work on the position to be riveted, so that the workpiece 2 to be riveted does not need to bear excessive axial pressure, the possibility of damage of the workpiece 2 to be riveted is reduced, and the safety and reliability of the riveting process are improved.

[0052] In a specific embodiment, as shown in Figure 2 The end of the pressing member 12 towards the connecting member 14 can be provided with a guide portion 121, and the guide portion 121 has a guide surface 122 which is inclined towards the connecting member 14. When the pressing member 12 moves along the axial direction of the riveting device 1, the guide portion 121 drives the connecting member 14 to rotate relative to the base 11, so that the connecting member 14 drives the riveting member 13 to move along the radial direction of the riveting device 1.

[0053] In the embodiment, the guide portion 121 is provided, and the guide surface 122 of the guide portion 121 is inclined towards the connecting member 14, so that when the pressing member 12 moves along the axial direction of the riveting device 1, the guide surface 122 of the guide portion 121 can guide the connecting member 14 to rotate, so that the driving force conducted to the connecting member 14 through the pressing member 12 can change direction through the rotation of the connecting member 14 and then be transmitted to the riveting member 13.

[0054] The end of the connecting member 14 in contact with the guide portion 121 can be provided with a rounded corner, so that the guide portion 121 and the connecting member 14 can move relative to each other, which can avoid affecting the normal work of the riveting device 1, reduce wear and tear, and prolong the service life of the above-mentioned components.

[0055] In a specific embodiment, as shown in Figure 2 The connecting member 14 can include a connecting rod 141 and a bracket 142, the bracket 142 is fixedly connected with the base 11, and the connecting member 14 can further include a rotating shaft 143, the connecting rod 141 is rotatably connected with the bracket 142 through the rotating shaft 143. The two ends of the connecting rod 141 are respectively abutted with the pressing member 12 and the riveting member 13.

[0056] In the embodiment, the connecting member 14 comprises a connecting rod 141 and a support 142 connected by a rotating shaft 143, and the support 142 is fixedly connected with the base 11, so that the connecting rod 141 can rotate relative to the base 11. Meanwhile, the two ends of the connecting rod 141 are respectively abutted with the pressing member 12 and the riveting member 13, so that the connecting rod 141 can transmit the acting force between the pressing member 12 and the riveting member 13, and the axial driving force of the pressing member 12 can be converted into the radial driving force of the riveting member 13 through the rotation of the connecting rod 141 relative to the base 11.

[0057] In the above embodiment, as shown in Figure 2 , the distance between the support 142 and the pressing member 12 can be greater than the distance between the support 142 and the riveting member 13. Specifically, the connecting rod 141 of the connecting member 14 rotates around the support 142 through the rotating shaft 143, so as to form a lever structure. In the lever structure, the connecting member 14 between the pressing member 12 and the support 142 is a power arm, and the connecting member 14 between the riveting member 13 and the support 142 is a resistance arm, so that the distance between the pressing member 12 and the support 142 is greater than the distance between the riveting member 13 and the support 142, thereby the length of the power arm in the lever structure is greater than the length of the resistance arm, so that it is a force-saving lever structure, thereby the axial driving force applied to the pressing member 12 can be reduced in the riveting process, so as to further reduce the axial pressure on the workpiece 2 to be riveted, and meanwhile, the radial driving force conducted to the riveting member 13 can meet the use requirement, thereby avoiding affecting the normal riveting work.

[0058] In a specific embodiment, as shown in Figure 2 and Figure 3 , the riveting member 13 can be installed on the side wall of the base 11, and the riveting device 1 can further comprise an elastic member 132, and the two ends of the elastic member 132 along the radial direction of the riveting device 1 are respectively abutted with the riveting member 13 and the side wall of the base 11.

[0059] In the embodiment, the elastic member 132 is arranged, and the two ends of the elastic member 132 along the radial direction of the riveting device 1 are respectively abutted with the riveting member 13 and the side wall of the base 11, when the pressing member 12 drives the riveting member 13 to move towards the workpiece 2 to be riveted through the connecting member 14, the elastic member 132 is compressed under the force, and when the pressing member 12 stops driving the riveting member 13 to move, the riveting member 13 can move away from the workpiece 2 to be riveted to the initial position under the action of the elastic force of the elastic member 132, thereby facilitating the subsequent use. In the embodiment, the riveting member 13 can automatically rebound to the initial position under the action of the elastic force of the elastic member 132, which has the advantages of simple structure and easy implementation, and can simplify the operation steps in the riveting process.

[0060] In a specific embodiment, as shown inFigure 2 , Figure 3 and Figure 5 As shown, the riveting component 13 may be provided with mounting holes 131, and the elastic component 132 is installed in the mounting holes 131. Arc-shaped protrusions 111 may be provided on both sides of the mounting holes 131 along the axial direction of the riveting device 1, and along the radial direction of the riveting device 1, there is a preset distance between the arc-shaped protrusions 111 and the connecting component 14.

[0061] In this embodiment, by providing mounting holes 131 on the riveting member 13, the elastic member 132 is installed in the mounting holes 131, which improves the connection reliability between the elastic member 132 and the riveting member 13, and also improves the stability when the elastic member 132 drives the riveting member 13 away from the base 11. Simultaneously, by providing arc-shaped protrusions 111 on both sides of the mounting holes 131 along the axial direction of the riveting device 1, the stability of the riveting member 13 during movement is further improved, and the arc shape of the protrusions avoids the installation position of the elastic member 132, preventing interference with the elastic member 132.

[0062] In addition, a preset distance is provided between the arc-shaped protrusion 111 and the connecting member 14 along the radial direction of the riveting device 1, so as to avoid interference between the riveting member 13 and the arc-shaped protrusion 111 when the riveting member 13 moves. Furthermore, by setting the arc-shaped protrusion 111, the maximum distance of the riveting member 13 can be limited, thereby improving the safety and reliability of the riveting device 1.

[0063] In one specific embodiment, such as Figure 2 , Figure 4 and Figure 5 As shown, a limiting part 112 may be provided on the inner wall of the base 11, which is used to limit the workpiece 2 to be riveted.

[0064] In this embodiment, by providing a limiting part 112 on the inner wall of the base 11, when the base 11 is connected to the workpiece 2 to be riveted, the limiting part 112 can cooperate with the limiting mating part on the workpiece 2 to be riveted to fix the workpiece 2 to be riveted and the base 11, so as to avoid relative movement between the workpiece 2 to be riveted and the base 11 during the riveting process, which would affect the normal progress of the riveting work.

[0065] Among them, such as 2 and Figure 5 As shown, in this embodiment, the limiting part 112 can be a protrusion, and the limiting mating part on the workpiece 2 to be riveted can be a recess. In other embodiments, the limiting part can also be a recess, and the limiting mating part can be a protrusion (not shown in the figure). The specific structure of the limiting part 112 and the limiting mating part is not limited in this application and can be adjusted according to the actual use.

[0066] In one specific embodiment, such as Figure 2 and Figure 4As shown, the top of the base 11 can be provided with a support end 113, and the cross-sectional area of the support end 113 is larger than that of the base 11 along the radial direction of the riveting device 1.

[0067] In this embodiment, the top of the base 11 is provided with a support end 113 for bearing the external power equipment, and the pressing member 12 is installed on the support end 113, and the support end 113 can provide support for the external power equipment when the external power equipment transmits an axial force to the pressing member 12. Therefore, the cross-sectional area of the support end 113 along the radial direction of the riveting device 1 is larger, which can reduce the axial pressure generated when the external power equipment provides an axial driving force to the pressing member 12, and can improve the connection stability and reliability of the two.

[0068] In a specific embodiment, as shown in Figure 2 and Figure 4 The base 11 can also be provided with a receiving cavity 114, and the receiving cavity 114 has an opening 115, and part of the structure of the connecting member 14 can extend out of the receiving cavity 114 through the opening 115.

[0069] In this embodiment, by providing the receiving cavity 114 in the base 11, at least part of the structure of the pressing member 12, the riveting member 13 and the connecting member 14 can be accommodated in the receiving cavity 114, which can protect them from direct contact with the external environment, and can prolong the service life of the riveting device 1. And the receiving cavity 114 has an opening 115, and part of the structure of the connecting member 14 can extend out of the receiving cavity 114 through the opening 115, which can reduce the overall volume of the base 11, thereby reducing the space occupied by the riveting device 1 when installed, and can avoid the movement of the connecting member 14, and facilitate the rotation of the connecting member 14 to transmit and change the direction of the driving force.

[0070] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Those skilled in the art can make various changes and modifications to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
