[0029] Example 1

[0030] Regarding the problem 1 mentioned above: most existing hot riveting devices rely on manual hot riveting, which makes it difficult to ensure the consistency of hot riveting between multiple workpieces when performing hot riveting operations, affecting product quality and resulting in low hot riveting efficiency.

[0031] The solution is as follows: An automated hot riveting device in this embodiment includes a frame 100, a hot riveting lifting plate 200, a hot riveting base plate 300, and a hot riveting head 400.

[0032] A cylinder 110 and a connecting valve 120 are mounted on the top of the frame 100. The cylinder 110 is located at the front end of the top of the frame 100, and the connecting valve 120 is located at the rear end of the top of the frame 100. The connecting valve 120 is connected to an external air compressor. A hot riveting lifting plate 200 is located on the side wall of the frame 100. The cylinder 110 has a movable end 111, the other end of which is connected to the top of the hot riveting lifting plate 200. The hot riveting lifting plate 200 is slidably connected to the side wall of the frame 100. The side wall of the frame 100 is equipped with... There is a first guide rail 130, and a connecting block 210 is installed on the side wall of the hot riveting lifting plate 200. The side wall of the connecting block 210 is slidably connected to the first guide rail 130. An installation plate 140 is installed at the bottom of the symmetrical side wall of the frame 100. The top of the installation plate 140 has bolt holes 141. The moving end 111 is driven to move up and down by the starting cylinder 110. The moving end 111 pushes the hot riveting lifting plate 200 to move up and down. The connecting block 210 slides along the first guide rail 130 to guide the hot riveting lifting plate 200.

[0033] Multiple hot riveting base plates 300 are detachably connected to the bottom of the hot riveting lifting plate 200. An upper bushing mounting plate 310 is installed on the side wall of the hot riveting base plate 300, and a lower bushing mounting plate 320 is installed at the bottom of the side wall of the hot riveting base plate 300. An upper bushing 311 is connected inside the upper bushing mounting plate 310, and a lower bushing 321 is connected inside the lower bushing mounting plate 320. A lifting block 330 is located between the lower bushing mounting plate 320 and the upper bushing mounting plate 310. A second guide rail 340 is installed on the side wall of the hot riveting base plate 300, and the side wall of the lifting block 330 is slidably connected to the second guide rail 340. The upper bushing 311 passes through the lifting block 330. The hot riveting head 400 is located below the lower bushing mounting plate 320, and an insulating seat 410 is installed on the top of the hot riveting head 400. A left conductive block 420 is installed on the left side of the insulating base 410, and a right conductive block 430 is installed on the right side of the insulating base 410. An insulating base fixing plate 440 is installed on the top of the insulating base 410, and a second connecting pipe 441 is installed on the top of the insulating base fixing plate 440. The second connecting pipe 441 passes through the lower bushing 321, the lifting block 330, and the upper bushing 311 in sequence and extends out from the top of the upper bushing mounting plate 310. The lifting block 330 is fixedly connected to the body of the second connecting pipe 441. The top of the second connecting pipe 441 has a connector 442, which is connected to the connecting valve 120 through the connecting pipe 121. A first spring 331 is installed on the top of the lifting block 331, and the top of the first spring 331 abuts against the top of the inner part of the upper bushing 311. When multiple workpieces need to be heated... During riveting, the same number of hot riveting base plates 300 are installed on the bottom of the hot riveting lifting plate 200 according to the number of workpieces. During hot riveting, the cylinder 110 is activated to drive the hot riveting lifting plate 200 to move up and down, realizing the pressing contact and separation between the hot riveting head 400 and the product. When the hot riveting head 400 is pressed into contact with the product, the first spring 331 is compressed. At this time, the cylinder 110 reaches the hard limit. During the hot riveting process, the hot riveting head 400 needs to move downward with the product riveting point. The holding force of the first spring 331 provides the downward power for the lifting block 330, the second connecting pipe 441, and the hot riveting head 400. The hot riveting head 400 is firmly connected to the left conductive block 420 and the right conductive block 430. The left conductive block 420 and the right conductive block 430 are insulated from each other by the insulating seat 410. Conductive block 420 and right conductive block 430 are connected to the hot riveting power supply via wires and are connected to voltage. The cross-section of the structure at the riveting position of the hot riveting head 400 is reduced, resulting in increased resistance. When current passes through, it will quickly raise the temperature of the riveting position of the hot riveting head 400 to the hot riveting temperature. When the hot riveting head 400 is pressed into contact with the product, the product's riveting point is melted by high temperature, and finally hot riveting is achieved. After completion, it needs to be cooled down quickly. The product's riveting point in the melted state is quickly solidified. At this time, compressed air is introduced into the connecting pipe 121 through the connecting valve 120. The bottom of the insulating seat 410 has an air hole, which is connected to the second connecting pipe 441. The compressed air inside the connecting pipe 121 is blown through the second connecting pipe 441 and finally blown out to the insulating seat 410. The air is blown out through the opening at the bottom of the insulating seat 410 to achieve cooling.

[0034] Example 2

[0035] Regarding the second problem to be solved above: most existing hot riveting heads are fixed, and the installation and disassembly operations are cumbersome, making it inconvenient to disassemble, inspect, or replace the hot riveting heads.

[0036] The solution is as follows: An automated hot riveting device in this embodiment also includes a limiting component 500.

[0037] The bottom of the hot riveting lifting plate 200 has a T-slot 220, and the top of the hot riveting base plate 300 has a T-plate 350. The T-plate 350 is slidably connected inside the T-slot 220. The bottom of the hot riveting lifting plate 200 has a miniature dense rack 230. The limiting component 500 includes a housing 510 installed on the side wall of the hot riveting base plate 300, a miniature dense gear 520 rotatably connected to the top of the housing 510 and meshing with the miniature dense rack 230, a slider 530 slidably connected inside the housing 510 and located below the miniature dense gear 520, and a second spring 540 installed at the bottom of the slider 530. The top of the slider 530 has a limiting groove 550 that cooperates with the miniature dense gear 520. The limiting groove 550 has a miniature dense tooth groove inside. When it is necessary to connect the hot riveting base plate 300 and the hot riveting lifting plate 200, the slider 530 is first pulled downward to compress the second spring 540. The miniature dense gear 520 separates from the limiting groove 550. At this time, the hot riveting base plate 300 is pushed to move towards the hot riveting lifting plate 200. The T-shaped plate 350 is embedded in the T-shaped groove 220 and slides along the T-shaped groove 220. When the hot riveting base plate 300 slides, the miniature dense rack 230 drives the miniature dense gear 520 to rotate until the hot riveting base plate 300 and the hot riveting head 400 are moved to the appropriate position. Then, the miniature dense gear 520 is released, and the second spring 540 rebounds to push the slider 530 to move upward. The miniature dense gear 520 is embedded in the limiting groove 550. The outer wall teeth of the miniature dense gear 520 mesh with the inner wall teeth of the limiting groove 550 to limit the miniature dense gear 520, that is, to limit the hot riveting base plate 300 and the hot riveting head 400. At this time, connecting the connecting pipe 121 to the connecting head 442 can quickly complete the installation of the hot riveting base plate 300 and the hot riveting head 400.

[0038] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
