Detailed Implementation

[0027] Please see Figure 1 In this embodiment of the invention, an automated hot riveting device for automotive air conditioning intake duct pipes includes a bracket 1. Two upper rotating frames 2 are symmetrically arranged on the bracket 1, and two lower rotating frames 3 are symmetrically arranged below the upper rotating frames 2. Riveting components 4 are provided in the upper rotating frames 2, and support plates 5 are provided in the lower rotating frames 3. The support plates 5 are C-shaped sheet metal. The support plates 5 on both sides can be fitted around the air duct pipe.

[0028] In this embodiment, a rotating rod 6 is fixed in the upper rotating frame 2, and the rotating rods 6 of the two upper rotating frames 2 are in opposite directions (up and down). The rotating rods 6 of the two upper rotating frames 2 are connected together by a telescopic cylinder 7. That is to say, the telescopic cylinder 7 can drive the two upper rotating frames 2 to rotate synchronously up and down by a certain angle.

[0029] In this embodiment, the rotating shafts of the upper rotating frame 2 and the lower rotating frame 3 on the same side are connected together by a pair of gears. That is, the rotation of the upper rotating frame 2 will drive the lower rotating frame 3 to rotate in the opposite direction. When the riveting component is between the two upper rotating frames 2 and the two lower rotating frames 3, by rotating the upper rotating frame 2 and the lower rotating frame 3, the riveting assembly 4 and the support plate 5 can clamp the riveting component from the top and bottom respectively, so that the riveting assembly 4 can rivet the riveting component tightly.

[0030] Please see Figure 2 In this embodiment, the support plate 5 has multiple connection holes 51 on the side near the riveting assembly 4, and each connection hole 51 contains a magnet. Inserting the rivet head into the connection hole 51 will fix the rivet in the support plate 5.

[0031] In this embodiment, a rotating plate 8 is rotatably provided in the support 1 below each of the lower rotating frames 3. A nozzle 9 is provided in the rotating plate 8 corresponding to the position of each connecting hole 51. A hot air blower 10 is provided on the back of the rotating plate 8.

[0032] In this embodiment, the rotating plate 8 is connected to the bracket 1 via a torsion spring. The torsion spring provides the elastic force that causes the rotating plate 8 to rotate downward. A guide plate 11 is fixed in the rotating plate 8. When the support plate 5 rotates downward, it pushes the guide plate 11 to rotate the rotating plate 8 upward, so that the rotating plate 8 is aligned with the support plate 5. At this time, the nozzle 9 is aligned with the rivet in the connecting hole 51 so as to heat and soften the rivet.

[0033] Please see Figures 3-5 In this embodiment, the riveting assembly 4 includes a fixing plate 41 and a pressure plate 42. The fixing plate 41 and the pressure plate 42 have the same shape as the support plate 5. The fixing plate 41 and the pressure plate 42 are movably connected to the upper rotating frame 2. A plurality of pressure rollers 43 are rotatably connected to the fixing plate 41, passing through its upper and lower surfaces. The pressure rollers 43 are eccentrically connected to the fixing plate 41. The pressure plate 42 has a plurality of vertically penetrating slots 45 corresponding to the position of each pressure roller 43. Each pressure plate 42 corresponds to a rivet in the connecting hole 51.

[0034] In this embodiment, a downwardly inclined push rod 44 is fixed at the pivot of the pressure roller 43. That is, when the fixing plate 41 and the pressure plate 42 are squeezed and brought close together, the push rod 44 rotates upward, causing the pressure roller 43 to rotate to the side away from the pivot and facing downward, so that the pressure roller 43 passes through the through groove 45 and squeezes the rivet downward, so that the tail of the rivet is flattened and fixed.

[0035] In this embodiment, the side of the pressure roller 43 is a concave arc-shaped surface. This allows the pressure roller 43 to compress the tail of the rivet into an arc shape. Furthermore, since the pressure roller 43 and the rivet are in rolling contact, the efficiency of rivet compression deformation is improved, and the rivet is prevented from being fixed to the pressure roller 43.

[0036] In this embodiment, a top bar 46 is provided above the pressure plate 42, corresponding to the position of the push rod 44, and the bottom of the top bar 46 is provided with multiple adjusting bolts 47 to adjust its height. When the fixed plate 41 and the pressure plate 42 are squeezed and brought close together, the top bar 46 pushes the push rod 44 upward, and the top bar 46 can be embedded in the fixed plate 41. By adjusting the height of the top bar 46 by adjusting the bolts 47, the angle of upward rotation of the push rod 44 when the fixed plate 41 and the pressure plate 42 are fully attached can be changed, thereby adjusting the depth of the pressure roller 43 pressing down on the rivet, so that the deformed rivet tail can be embedded in the riveted part to different depths.

[0037] In practice, the car air conditioning intake duct that needs to be hot-riveted is placed in the working area of ​​the equipment, ensuring that the duct is aligned with the riveting components of the equipment. The upper and lower rotating frames of the equipment are opened, and the duct is placed on the C-shaped plates on both sides of the support plate, ensuring that the duct is securely clamped in the support plate. The rivets are placed in the connecting holes on the support plate, and the hot air is turned on so that the hot air is directed through the nozzles to the rivets in the connecting holes on the support plate. The hot air softens the rivets, preparing them for the subsequent extrusion riveting process.

[0038] Then, by controlling the telescopic cylinder, the two upper rotating frames rotate synchronously up and down. The rotation of the upper rotating frames drives the lower rotating frame to rotate in the opposite direction, clamping the riveting assembly and the support plate into the air duct from the top and bottom respectively. At this time, the pressure roller in the riveting assembly squeezes the rivet in the connection hole to form a solid connection. The pressure roller flattens the rivet tail through rolling contact, ensuring the strength and stability of the connection. After the pressing is completed, wait for the connection to cool and solidify to ensure the stability and durability of the connection.

[0039] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
