The lifting drive mechanism 2 is installed at the top of the mechanism, and the driving end of the lifting drive mechanism 2 is connected to the hot riveting mechanism 3, and the hot riveting mechanism 3 is slidably matched with the frame 1.

[0028] like Figure 1As shown, the hot riveting mechanism 3 includes a support plate 31, a fixed plate 32 and two hot riveting devices 33. The driving end of the lifting drive mechanism 2 is connected to the support plate 31, the support plate 31 is slidably matched with the frame 1, the fixed plate 32 is connected to the bottom of the support plate 31, and the two hot riveting devices 33 are symmetrically installed at the bottom of the fixed plate 32. The two hot riveting devices 33 correspond to the two positioning fetal membranes 4 respectively.

[0029] like Figure 1 and Figure 2 As shown, the hot riveting device 33 includes a plurality of adjustable hot riveting components 331, a plurality of pre-pressing components 332 for pre-pressing the door panel armrests, and a plurality of cooling components 333 for cooling the door panel armrests.

[0030] Specifically, the frame 1 includes a top plate, a bottom plate, and four support columns, and the top plate and the bottom plate are connected by the four support columns. The four end corners of the support plate 31 of the hot riveting mechanism 3 are respectively provided with guide sleeves, which are mounted on the four support columns. The support plate 31 slides with the four support columns. The fixed plate 32 is connected to the bottom of the support plate 31. Two hot riveting devices 33 are symmetrically arranged at the bottom of the fixed plate 32. The hot riveting device 33 includes 18 hot riveting components 331, 6 pre-pressing components 332, 18 second air blowing pipes 106, and 12 first air blowing pipes 105. The 18 second air blowing pipes 106 are respectively installed at the side ends of the 18 hot riveting components 331. Among the 12 first air blowing pipes 105, 6 first air blowing pipes 105 are installed on one side of the hot riveting component 331 and the pre-pressing component 332, and the other 6 first air blowing pipes 105 are installed on the other side of the hot riveting component 331 and the pre-pressing component 332.

[0031] First, the two door panel handrails are fixed to two positioning molds. Then, the lifting drive mechanism 2 drives the support plate 31, which drives the fixing plate 32 and two hot riveting devices 33 downward to perform hot riveting operations on the two door panel handrails simultaneously. During the downward pressing process, the six pre-pressing components 332 of the hot riveting device 33 first simultaneously press the door panel handrails. Continuing the downward pressure, the 18 hot riveting components 331 simultaneously perform hot riveting operations on the 18 hot riveting locations of the door panel handrails. After hot riveting, the 18 second air blowing pipes 106 and the 12 first air blowing pipes 105 respectively blow air to cool the hot riveted locations of the door panel handrails, accelerating the curing efficiency of the hot riveted locations.

[0032] In the above structure, the provision of two hot riveting devices 33 and two positioning molds accelerates the hot riveting efficiency of the door panel armrest. The provision of a cooling assembly 333 provides air cooling to the hot riveted door panel armrest, accelerating the curing efficiency of the hot-riveted areas of the door panel armrest. This automotive door panel armrest hot riveting equipment not only improves hot riveting efficiency but also enhances curing efficiency after hot riveting, ensuring a high yield of hot-riveted door panel armrests.

[0034] Specifically, one end of the connecting rod 102 is adjustably connected to the fixing plate 32 via a first bolt assembly, and the position of the connecting rod 102 can be adjusted by adjusting the bolt assembly. One end of the fixing rod 101 extends into the other end of the connecting rod 102 and is then adjustably connected via a second and third bolt assemblies. The height of the fixing rod 101 can be adjusted by adjusting the second and third bolt assemblies. The other end of the fixing rod 101 is provided with a thread, and the hot rivet head 100 is provided with a threaded connection. The hot rivet head 100 and the fixing rod 101 are threadedly connected, and the welding angle of the hot rivet head 100 can be adjusted by rotating the hot rivet head 100.

[0035] This arrangement facilitates adjustment of the welding points of the hot rivet head 100 according to the welding parts of the product, thereby improving the welding versatility of the equipment.

[0036] like Figure 3 As shown, in one embodiment, the pressing assembly of the automobile door panel armrest hot riveting equipment includes a pre-pressing head 103 and an elastic component 104, one end of the elastic component 104 is connected to the fixing plate 32, and the other end of the elastic component 104 is connected to the pre-pressing head 103.

[0037] Specifically, the elastic component 104 includes a sleeve, a spring, and a guide post. The sleeve is connected to the fixed plate 32, and the sleeve is mounted on the guide post and the spring. One end of the guide post is located in the sleeve, and the other end of the guide post is connected to the pre-pressing head 103. One end of the spring rests on the fixed plate 32, and the other end of the spring rests on the guide post. When the pre-pressing head 103 presses the door panel handrail, the pre-pressing head 103 drives the guide post to move upward, and the spring provides a reverse pressing force to the guide post and the pre-pressing head 103. When the pre-pressing head 103 releases the door panel handrail, the pre-pressing head 103 resets under the action of the spring force. This arrangement facilitates continuous compression of the pre-pressing head 103 and also acts as a buffer.

[0038] like Figure 1 and Figure 4 As shown, in one embodiment, the cooling component 333 of the automobile door panel armrest hot riveting equipment includes a plurality of first air blowing pipes 105 and a plurality of second air blowing pipes 106, the plurality of first air blowing pipes 105 are respectively connected to the fixing plate 32, and the plurality of second air blowing pipes 106 are respectively connected to the plurality of hot riveting components 331, and the first air blowing pipes 105 and the second air blowing pipes 106 are respectively used for blowing cooling to the door panel armrest after hot riveting.

[0039] Specifically, 18 first air blowing pipes 105 and 12 second air blowing pipes 106 are provided. The 12 second air blowing pipes 106 cool the door panel armrest from both sides, while the 18 first air blowing pipes 105 cool the door panel after hot riveting. This configuration greatly improves the cooling efficiency of the door panel armrest, thereby improving the fixing efficiency after hot riveting and ensuring product quality.

[0040] like Figure 5 As shown, in one embodiment, the positioning mold of the automobile door panel armrest hot riveting equipment includes a contour carrier 41, a plurality of positioning platforms 42 and a plurality of baffles 43, the plurality of positioning platforms 42 are located on one side of the contour carrier 41, the contour carrier 41 and the plurality of positioning platforms 42 are used to position the door panel armrest, the plurality of baffles 43 are respectively located on the side ends of the contour carrier 41 and the positioning platform 42, and the plurality of baffles 43 are used to position the side ends of the door panel armrest.

[0041] Specifically, a contouring platform 41, two positioning platforms 42, and five baffles 43 are mounted on the bottom plate of the frame 1. The two positioning platforms 42 are positioned correspondingly and located at one end of the contouring platform 41. The five baffles 43 are respectively arranged around the side ends of the contouring platform 41 and the two positioning platforms 42. The door panel handrail is placed on the contouring platform 41 and the two positioning platforms 42, and the five baffles 43 respectively position the side ends of the door panel handrail.

The motor 21 is used to drive the transmission mechanism 22 to drive the lifting rod 23 to move up and down.

[0044] Specifically, the motor 21 drives the transmission mechanism 22 to rotate, and the transmission mechanism drives the lifting rod 23 to move up and down. This arrangement facilitates driving the lifting rod 23 to drive the support plate 31 and the hot riveting device 33 to move and fix and hot rivet the door panel handrail on the positioning mold.

[0045] like Figure 1 As shown, in one embodiment, a limit assembly 5 is installed on the frame 1 of the automotive door panel armrest hot riveting equipment. The limit assembly 5 includes a cylinder and a limit head for limiting the position of the lifting rod 23.
