[0018] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0019] like Figures 1 to 6 As shown, a multi-point riveting device for a heat insulation cover includes a base plate 1. A positioning seat 2 and several riveting seats 3 are detachably fixed on the base plate 1. The riveting seats 3 are respectively set at corresponding riveting positions. The positioning seat 2 has a first blind hole 200. A first lifting member 21 is slidably installed in the first blind hole 200. A first elastic member 23 is provided between the first blind hole 200 and the first lifting member 21. The first elastic member 23 makes the first lifting member 21 always tend to move away from the base plate 1. The first lifting member 21 is provided with a positioning boss 213. The positioning boss 213 corresponds to and cooperates with the through hole on the heat insulation cover, thereby playing the role of positioning and placing the heat insulation cover. The first elastic member 23 can play a buffering role when the first lifting member 21 is pressed down during riveting.

[0020] Each of the riveting bases 3 is provided with a second blind hole 300. A second lifting member 31 is slidably installed in each of the second blind holes 300. A second elastic member 34 is provided between the second blind hole 300 and the second lifting member 31. The second elastic member 34 makes the second lifting member 31 always tend to move away from the base plate 1. Each of the second lifting members 31 is detachably installed with a riveting block 32. Each of the riveting blocks 32 is provided with a groove 320. The groove 320 is used to place rivets, and the riveting block 32 with different sized grooves 320 can be replaced according to different types of rivets.

[0021] The positioning base 2 is provided with a plurality of positioning holes 201, and a fixing pin 22 is detachably installed in each positioning hole 201. The fixing pin 22 is used to fix the heat insulation cover to the first lifting member 21. The fixing pin 22 has a limiting part 221 and a plugging part 222. The plugging part 222 can be inserted into the positioning hole 201. The limiting part 221 is limited and matched with the connection hole of the heat insulation cover. Further optimized, the plugging part 222 is provided with a first magnet 223, and the bottom of the positioning hole 201 is provided with a second magnet 202. The first magnet 223 and the second magnet 202 are magnetically matched. The magnetic matching can guide the installation of the fixing pin 22 and make the installation faster.

[0022] Each of the riveting blocks 32 is provided with at least two first positioning posts 33. Each first positioning post 33 includes a first columnar surface 332 and a first guide portion 331. The first positioning post 33 is matched with the holes on the heat insulation cover. By matching the first positioning post 33 with the corresponding holes, the heat insulation cover is further positioned. The first guide portion 331 is a conical surface, which makes it easier for the holes on the heat insulation cover to match and connect with the first positioning post 33.

[0023] The first lifting component 21 includes a first connecting plate 211 and a first connecting rod 212. The first connecting plate 211 is installed at one end of the first connecting rod 212. The first connecting rod 212 is slidably fitted in the first blind hole 200. The positioning seat 2 has a first clearance groove 20 that cooperates with the first connecting plate 211. When the first connecting plate 211 is completely located in the first clearance groove 20, the upper surface of the first connecting plate 211 is flush with the upper surface of the positioning seat 2, thereby increasing the stress support surface of the heat insulation cover and making the riveting process more stable. The second lifting component 31 includes a second connecting plate 311 and a second connecting rod 312. The second connecting plate 311 is installed at one end of the second connecting rod 312. The second connecting rod 312 is slidably fitted in the second blind hole 300. The positioning seat 2 has a second clearance groove 30 that cooperates with the second connecting plate 311. When the second connecting plate 311 is completely located in the second clearance groove 30, the upper surface of the second connecting plate 311 is flush with the upper surface of the riveting seat 3, thereby increasing the stress support surface of the heat insulation cover and making the riveting process more stable.

[0024] The first connecting plate 211 is provided with a plurality of second positioning posts 214. Each second positioning post 214 includes a second columnar part 2142 and a second guide part 2141. The second positioning post 214 cooperates with the corresponding hole to further perform the function of positioning the heat insulation cover. The second guide part 2141 is a conical surface, which makes it easier for the hole on the heat insulation cover to cooperate and connect with the second positioning post 214.

[0025] The beneficial effects of this application are as follows: By setting a positioning seat 2 and multiple riveting seats 3 on the base plate 1, precise positioning and simultaneous multi-point riveting of the heat insulation cover are achieved, effectively improving riveting efficiency and consistency. The first lifting component 21 in the positioning seat 2, in conjunction with the first elastic component 23, can both initially position the heat insulation cover through the positioning boss 213 and provide buffering during riveting to prevent damage to the heat insulation cover due to hard contact. The second lifting component 31 and the second elastic component 34 of the riveting seat 3 ensure that the riveting block 32 can adapt to different heights during riveting. Combined with replaceable riveting blocks 32, it can adapt to the riveting requirements of different types of rivets, enhancing the versatility of the device. The fixing pin 22 is quickly installed through magnetic engagement and further secures the heat insulation cover with the positioning hole 201, preventing displacement during riveting. The conical guide design of the first positioning post 33 and the second positioning post 214 makes the positioning and installation of the heat insulation cover more convenient and accurate. The overall structure is compact and reasonable, simple to operate, greatly reducing manual labor intensity and improving production efficiency and product quality.

[0026] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this utility model.
