Therefore, the terms describing the positional relationship in the drawings are only for exemplary illustration and cannot be understood as a limitation of this patent. For those of ordinary skill in the art, the specific meanings of the above terms can be understood according to specific circumstances.

[0027] Here, it should also be noted that in order to avoid obscuring the present utility model with unnecessary details, only the structures and / or processing steps closely related to the solution of the present utility model are shown in the drawings, and other details less related to the present utility model are omitted.

[0028] The embodiments of the present utility model provide a multi-riveting head hot riveting assembly with adjustable riveting head spacing and a hot riveting device including the multi-riveting head hot riveting assembly.

[0029] As Figure 1 shown, the hot riveting device includes a multi-riveting head hot riveting assembly 1 and a driving assembly 2 for driving the movement of the multi-riveting head hot riveting assembly 1. The driving assembly 2 can be a lifting driving assembly, such as a Z-axis linear driving module, and can be an electric cylinder or a cylinder, etc. When performing riveting, the driving assembly 2 drives the multi-riveting head hot riveting assembly 1 to descend and press against the workpiece to be processed for riveting. After the riveting is completed, the driving assembly 2 drives the multi-riveting head hot riveting assembly 1 to rise away from the workpiece to be processed.

[0030] In the embodiments of the present utility model, referring to Figure 2 and Figure 3 , the multi-riveting head hot riveting assembly 1 mainly includes a support plate 11, a first mounting plate 12, a second mounting plate 13, a riveting head module 14, a spacing adjusting mechanism 15, and a vision positioning module 16. Among them, the multi-riveting head hot riveting assembly 1 is connected to the driving assembly 2 through the support plate 11.

[0031] Among them, a first slide rail 111 is provided on the support plate 11. The first mounting plate 12 and the second mounting plate 13 are respectively slidably connected to the first slide rail 111, and the first mounting plate 12 is fixedly connected to the support plate 11 through a detachable fastener 112 (such as a screw). The number of the riveting head modules 14 is at least two, which are respectively connected to the first mounting plate 12 and the second mounting plate 13. The spacing adjusting mechanism 15 is connected to the support plate 11 and connected to the second mounting plate 13. The spacing adjusting mechanism 15 is used to drive the second mounting plate 13 to slide relative to the first mounting plate 12 on the first slide rail 111, so as to adjust the spacing between the first mounting plate 12 and the second mounting plate 13, and further adjust the spacing between the riveting head modules 14 connected to the first mounting plate 12 and the second mounting plate 13. The vision positioning module 16 is connected to the support plate 11 and is located on the side of the riveting head module 14. The vision positioning module 16 is mainly used to obtain the position information of the riveting point.

[0032] Specifically, as Figure 3 shown, the spacing adjusting mechanism 15 includes a support base 151, an adjusting screw 152 and a connecting block 153. The support base 151 is connected to the support plate 11. The first end of the adjusting screw 152 is rotatably installed on the support base 151 and is provided with a rotating part 154. A screw hole 155 adapted to the adjusting screw 152 is provided in the connecting block 153. The connecting block 153 is threadedly connected to the second end of the adjusting screw 152 through the screw hole 155. The second mounting plate 13 is connected to the connecting block 153. By rotating the adjusting screw 152, the connecting block 153 moves on the adjusting screw 152, and then drives the second mounting plate 13 to slide on the first slide rail 111. Thus, the spacing between the first mounting plate 12 and the second mounting plate 13 is continuously adjustable.

[0033] Furthermore, a locking block 156 is provided on the support base 151. The locking block 156 is used to lock the adjusting screw 152 after the connecting block 153 moves to a predetermined position, so as to prevent the connecting block 153 from moving after the position is adjusted. Even further, a stop portion 157 is provided on the adjusting screw 152. The stop portion 157 is located between the support base 151 and the connecting block 153.

[0034] In this embodiment, as a preferred solution, as Figure 3As shown, two first slide rails 111 are provided on the support plate 11. The two first slide rails 111 are spaced apart from each other and arranged in parallel on the support plate 11. The first mounting plate 12 and the second mounting plate 13 are respectively slidably connected to the two first slide rails 111. This can make the sliding of the first mounting plate 12 and the second mounting plate 13 more stable.

[0035] Further, as Figure 3 shown, the second mounting plate 13 is connected to the two first slide rails 111 through a first slider 113. The first slider 113 supports the second mounting plate 13 on the support plate 11 and makes a gap between the second mounting plate 13 and the support plate 11. Thus, it can be avoided that the second mounting plate 13 rubs against the support plate 11 when sliding on the first slide rail 111, and the driving of the second mounting plate 13 by the pitch adjusting mechanism 15 can be made smoother.

[0036] Among them, the number of the first mounting plates 12 is more than two, and at least one of the first mounting plates 12 is connected with the riveting head module 14. As a specific case, in this embodiment, as Figure 2 shown, the number of the first mounting plates 12 is three, and two of the first mounting plates 12 are connected with the riveting head module 14.

[0037] In this embodiment, refer to Figure 4, the riveting head module 14 includes a first connecting plate 141, a second connecting plate 142, a third connecting plate 143, a lifting drive mechanism 144, a heat insulation plate 145, a heating block 146, a riveting head 147, and a blowing copper pipe 148. A second slide rail 141a is provided on the first connecting plate 141. The second connecting plate 142 is slidably connected to the second slide rail 141a through a second slider 142a. The third connecting plate 143 is connected to the top of the first connecting plate 141. The lifting drive mechanism 144 is connected to the third connecting plate 143. The power output end of the lifting drive mechanism 144 is connected to the upper end of the second connecting plate 142. The heat insulation plate 145 is connected to the lower end of the second connecting plate 142. The heating block 146 is connected to the lower end of the heat insulation plate 145. The riveting head 147 is connected to the heating block 146. The blowing copper pipe 148 sequentially passes through the third connecting plate 143, the second connecting plate 142, and the heat insulation plate 145 and extends above the riveting head 147. Among them, the riveting head module 14 is connected to the first mounting plate 12 or the second mounting plate 13 through the first connecting plate 141. Among them, the heating block 146 is connected to an external heat source (not shown in the figure) and is used to heat the riveting head 147 during riveting, so that the riveting components are connected to each other in a hot melting manner at the riveting point. The blowing copper pipe 148 is connected to an external cooling air source (not shown in the figure). After the riveting head 147 is hot melted to connect the riveting components to each other, cooling gas is sprayed onto the riveting head 147 for cooling, so that the hot melted connected riveting components are cooled and solidified. The lifting drive mechanism 144 is mainly used to drive the second connecting plate 142 to slide upward after riveting is completed, driving the riveting head 147 to be demolded from the riveting components, and an electric cylinder or a cylinder can be used.

[0038] For the multi-riveting head hot riveting assembly and its corresponding hot riveting device provided in the above embodiment, according to the spacing of the riveting points on the workpiece to be processed, combined with the spacing of the first mounting plate 12 fixedly connected to the support plate 11 and the second mounting plate 13 with continuously adjustable spacing, determine the number of riveting points that can be riveted simultaneously, and assemble the corresponding number of riveting head modules 14 onto the first mounting plate 12 and the second mounting plate 13. Take Figure 2 the shown hot riveting assembly as an example:

[0039] (1) If the spacings between the three first mounting plates 12 can all match the spacing of the riveting points, adjust the spacing of the second mounting plate 13 to match the spacing of another riveting point. A total of four riveting points can be matched. At this time, four first mounting plates 12 and the second mounting plate 13 are all assembled with riveting head modules 14, and the four riveting points can be riveted simultaneously.

[0040] (2) If the spacing between two of the three first mounting plates 12 (for example, the first and the third from left to right in the figure) can match the spacing of the riveting points, adjust the spacing of the second mounting plate 13 to match the spacing of the other riveting point. In total, three riveting points can be matched. At this time, the two first mounting plates 12 and the second mounting plate 13 are assembled with the riveting head module 14, and the three riveting points can be riveted simultaneously.

[0041] (3) If the spacing between any two first mounting plates 12 cannot match the spacing of the riveting points, select one of the first mounting plates 12 and adjust the spacing between the second mounting plate 13 and this second mounting plate 12 to match two riveting points. At this time, the riveting head module 14 is assembled on the second mounting plate 13 and the corresponding first mounting plate 12, and the two riveting points can be riveted simultaneously. In addition, since any one of the first mounting plates 12 can be selected to be adjusted and matched with the second mounting plate 13, the range of its spacing adjustment is relatively large, with high flexibility, which improves the versatility of the equipment.

[0042] Therefore, the hot riveting assembly provided in this embodiment can perform hot riveting operations on at least two or more riveting points simultaneously, improving the production efficiency compared with the existing single-point riveting method one by one. At the same time, the spacing of the riveting head modules in the hot riveting assembly is adjustable, which can be applied to multiple different specifications of products with different spacing of riveting points, with high versatility of the equipment, reducing the use cost and production cost of the equipment.

[0043] Furthermore, when the number of riveting points of the product to be processed is large and the distribution range is wide, multiple such hot riveting assemblies (which can be independently driven respectively) can be assembled in the hot riveting device to perform hot riveting operations simultaneously, further improving the operation efficiency and taking into account the problems of improving production efficiency and equipment versatility.

[0044] The above are only the specific embodiments of the present application. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present application, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present application.
