DETAILED DESCRIPTION

[0026] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0027] See also Figure 1 An embodiment of the present application provides a riveting device 100, which includes a supporting component 1, a power component 2, a riveting component 3 and a guiding component 4.

[0028] See also Figure 1 In some embodiments, the main body of the power assembly 2 is connected to the support assembly 1. The main body of the power assembly 2 is connected to the support assembly 1. Figure 2 The riveting assembly 3 includes a lever member 31 and a plurality of riveting heads 32. The middle portion 311 of the lever member 31 is connected to the output end of the power assembly 2. The lever member 31 includes a plurality of ends 312 away from the middle portion 311 thereof. Each end 312 is respectively connected to a riveting head 32. The power assembly 2 is configured to drive the lever member 31 to drive all the riveting heads 32 to simultaneously rivet the workpiece 11, along the riveting direction (such as Figure 1 and Figure 3 R direction), the distance d between each end 312 and the middle 311 is the same (as shown in FIG. Figure 3The distance d shown in the figure). When the power assembly 2 outputs power, the middle part 311 of the lever member 31 is used as the fulcrum, and the power will generate a force on the end 312 of the lever member 31. According to the principle of force decomposition and balance, the power assembly 2 applies the same force component on each end 312 along the riveting direction, so that the riveting force on each riveted joint 32 is equal. The same riveting force acts on the workpiece 11 to be processed, which will produce a consistent connection effect, thereby ensuring the riveting quality. Compared with the current single-point riveting, multi-point riveting is achieved by setting the lever member 31, so that multiple riveted joints 32 can be riveted at the same time, which can save riveting time and improve production and processing efficiency.

[0029] Please note that Figure 3 The P direction and the R direction in the figure, the P direction refers to the oblique direction of the lever member 31 from the middle portion 311 thereof to the end portion 312, and the R direction refers to the riveting direction of the lever member 31. 1 L is the oblique length from one end 312 to the middle 311 along the P direction, 2 θ is the oblique length from the other end 312 to the middle 311 along the P direction. 1 is the angle at which one end portion 312 deviates from the middle portion 311 along the R direction, θ 2 is the angle at which the other end 312 deviates from the middle portion 311 along the R direction. d is the effective distance between each end 312 and the middle portion 311 along the R direction.

[0030] It can be understood that according to the principle of force decomposition and balance, along the riveting direction (R direction), the distance d between each end 312 and the middle part 311 is the same, which can keep the force component of each end 312 along the R direction consistent. The distance d is the effective distance obtained by the combined effect of the oblique length and the angle, satisfying: L 1 • sinθ 1 =L 2 • sinθ 2 =d. Therefore, in some embodiments, L 1 and L 2 Can be equal or unequal, corresponding to, θ 1 and θ 2 Can be equal or unequal. When L 1 Greater than L 2 When θ 1 Less than θ 2 ; When L 1 Less than L 2 When θ 1 Greater than θ 2 In other words, the embodiments of the present application do not specifically limit the oblique length and angle, and any oblique length and angle that can keep the effective spacing d the same are within the protection scope of the embodiments of the present application.

[0031] For example, see Figure 2 In some embodiments, all the ends 312 are symmetrically arranged along the axis of the output end of the power assembly 2, and the shape and size of each end 312 are the same. Since the ends 312 are symmetrically arranged and have the same shape and size, the power of the power assembly 2 will be evenly distributed to each end 312 along the symmetry axis, so that the magnitude and direction of the force received by each end 312 are the same, making the riveting effect more uniform. And because the lever components 31 are symmetrically arranged, the overall stability of the riveting assembly 3 is higher.

[0032] In other embodiments, the direction from the middle portion 311 of the lever member 31 to the end portion 312 (eg Figure 3 In other words, along the P direction, one end 312 of the lever member 31 is farther from the middle part 311, and the angle between the end 312 and the middle part 311 is smaller, and the other end 312 is closer to the middle part 311, and the angle between the end 312 and the middle part 311 is larger. In this way, according to the force decomposition, the force component of each end 312 along the riveting direction can be guaranteed to be the same. In this case, the lever member 31 can better adapt to complex spatial conditions, can bypass obstacles for riveting, and can increase the riveting range of the riveting head 32.

[0033] See also Figure 2 , in order to achieve riveting on planes of different heights. In some embodiments, at least two riveting heads 32 have different lengths along the riveting direction (R direction). In other words, the two riveting heads 32 have a height difference along the riveting direction, so that the uneven workpiece 11 can be riveted. At this time, the riveting force on each riveting head 32 is the same, and the riveting effect of consistent quality can be maintained on surfaces of different heights.

[0034] See also Figure 2 In some embodiments, the power assembly 2 includes a telescopic driver 21 and an adapter plate 22, one side surface of the adapter plate 22 is connected to the output end of the telescopic driver 21, and the other side surface of the adapter plate 22 facing away from the telescopic driver 21 is connected to the middle portion 311 of the lever member 31. The adapter plate 22 can transmit the power of the telescopic driver 21 to the lever member 31. Since the adapter plate 22 has a larger contact area, it can receive and transmit the power of the telescopic driver 21 more evenly, and can increase the stability of the connection, reduce vibration and shaking during the riveting process, and ensure the smooth movement of the riveting head 32 when riveting the workpiece 11 to be processed.

[0035] In some embodiments, the telescopic driver 21 may be a telescopic air cylinder, a telescopic electric cylinder, a telescopic gas-liquid booster cylinder, a telescopic cam or other structures, which is not specifically limited in the embodiments of the present application.

The arrangement of the guide assembly 4 can guide the movement direction and movement path of the lever member 31, reduce the offset and shaking of the lever member 31 during the movement, ensure the accuracy of the riveting position, and improve the riveting accuracy and consistency.
