[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] Example 1

[0020] like Figure 1-4 As shown, it is the first embodiment of the present invention, which provides a hot riveting mechanism for flipping the automobile interior ceiling, including a rotating cylinder 2, the output end of the rotating cylinder 2 is connected to a coupling 3, and the other end of the coupling 3 is connected to a shaft rod 4, the surface of the shaft rod 4 is connected to a connecting arm 5, one end of the connecting arm 5 is provided with a hot riveting assembly, and the hot riveting assembly includes a riveting cylinder 9, the output end of the riveting cylinder 9 is connected to a riveting block 10, and the inner cavity of the riveting block 10 is provided with a dry-burning heater, the bottom of the riveting cylinder 9 is provided with a spring mechanism 11, and the bottom of the spring mechanism 11 is provided with a pre-pressing block 12, a brake latch cylinder 7 and a latch rod 8 are respectively provided on one side of the connecting arm 5, the output end of the brake latch cylinder 7 is connected to the latch rod 8, the latch rod 8 extends to the inner cavity of the connecting arm 5 away from one end of the brake latch cylinder 7, and is movably connected to the inner cavity of the connecting arm 5, and a limiting member 6 is provided on the surface of one end of the shaft rod 4.

[0021] like Figure 1-4As shown, the coupling 3 can be driven to rotate by the operation of the rotating cylinder 2, and the coupling 3 can be driven to rotate while the shaft rod 4 is rotated. Since the shaft rod 4 is connected to the connecting arm 5, the connecting arm 5 can be turned while the shaft rod 4 is rotated, so that the connecting arm 5 can drive the hot riveting assembly to turn over. After the hot riveting assembly is turned into place, the shaft rod 4 is locked and positioned by the limiter 6 to ensure that the shaft rod 4 does not rotate. At the same time, the output end of the brake latch cylinder 7 drives the latch rod 8 to move to one side, so that the latch rod 8 will gradually extend to the inner cavity of the connecting arm 5, thereby realizing the positioning of the connecting arm 5 and ensuring its flipping. The stability after the riveting is completed can be prevented from displacement and the like during the subsequent riveting process. Afterwards, the reset force of the spring mechanism 11 can drive the pre-compression block 12 to press the surrounding area to be riveted, and at the same time, the dry-burning heater inside the riveting block 10 is used to heat the riveting block 10. The heat on the surface of the riveting block 10 will be transferred to the material, so that the material is heated and softened, and the output end of the riveting cylinder 9 drives the riveting block 10 and the softened material to contact with the substrate, thereby realizing the hot riveting operation. The present application can not only ensure the efficiency and quality of hot riveting by flipping the hot riveting assembly, but also meet the hot riveting needs of various interior ceiling products.

[0022] Example 2

[0023] Reference Figure 1 and 3 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0024] In this embodiment, the bottom of the rotating cylinder 2 is fixedly connected to the mounting base 1, the surface of the mounting base 1 is fixedly connected to the shock-absorbing buffer block 14, one side of the connecting arm 5 is in contact with the surface of the shock-absorbing buffer block 14, and the shock-absorbing buffer block 14 is a polyurethane pad.

[0025] The top of the mounting base 1 is fixedly connected to a shaft seat 15, the connecting arm 5 is located in the inner cavity of the shaft seat 15 and is movably connected to the inner cavity of the shaft seat 15, one side of the limiter 6 is connected to the shaft seat 15, the shaft rod 4 passes through the inner cavity of the shaft seat 15, and is movably connected to the inner cavity of the shaft seat 15 through a bearing.

[0026] A support 16 is fixedly connected to the left side of the top of the mounting base 1 , and one side of the brake latch cylinder 7 is fixedly connected to the support 16 .

[0027] like Figure 1 and 3As shown, the device can be stably supported by installing the base 1 to ensure its stability during operation. When the connecting arm 5 contacts the shock-absorbing buffer block 14 during the flipping process, the shock-absorbing buffer block 14 is a polyurethane pad, so the connecting arm 5 can be protected during contact to prevent the connecting arm 5 from being worn. At the same time, the vibration generated by the contact impact can be buffered. The shaft seat 15 can be used to provide limited support for the shaft rod 4 to ensure the stability of the shaft rod 4 during rotation. The support 16 can be used to stably support the brake latch cylinder 7 to prevent the brake latch cylinder 7 from falling off or misaligned during operation.

[0028] Example 3

[0029] Reference Figure 2 and 4 , which is the third embodiment of the present invention, and this embodiment is based on the previous two embodiments.

[0030] In this embodiment, stroke adjustment screws 13 are connected to both sides of the riveting cylinder 9, and the bottom of the stroke adjustment screw 13 is connected to the spring mechanism 11. A guide rail 17 is provided on one side of the connecting arm 5. The spring mechanism 11 includes a spring and a connecting frame. One side of the connecting frame extends to the inner cavity of the guide rail 17 and is slidably connected to the inner cavity of the guide rail 17. The bottom of the spring is connected to the top of the pre-load block 12.

[0031] The limit member 6 includes a limit block, a bolt and a nut, and the limit block is sleeved on the surface of one end of the shaft rod 4. A connecting hole is opened on the top of the limit block, and a screw is fixedly connected to the inner cavity of the connecting hole. The surface of the screw is threadedly connected to the nut, and the bottom of the nut is in contact with the limit member 6.

[0032] like Figure 2 and 4 As shown, the upper or lower limit of the working range of the spring mechanism 11, the pre-pressing block 12 and the riveting cylinder 9 can be adjusted and set by the stroke adjustment screw 13 to ensure that the predetermined stroke or position will not be exceeded during operation, and during the adjustment process, the connecting frame will slide along the inner cavity of the guide rail 17, thereby realizing the limit guide to prevent misalignment during the adjustment process. The pre-pressing block 12 can be driven to move by the reset elastic force of the spring, so that the pre-pressing block 12 can be pressed around the area to be riveted, and the limit of the shaft rod 4 can be realized by the limit piece 6. In actual operation, The nut can be rotated in the forward direction. Due to the threaded connection between the nut and the screw, the nut will gradually move downward and contact the limit block while rotating, thereby applying pressure to the limit block, causing its inner cavity to gradually shrink until it contacts the shaft 4, thereby limiting the shaft 4. Conversely, by rotating the nut in the reverse direction, due to the threaded connection between the nut and the screw, the nut will gradually move upward and lose contact with the limit block while rotating, thereby causing the limit block to lose pressure, and its inner cavity gradually expands, giving the shaft 4 sufficient room for movement, thereby releasing the limit on the shaft 4.

[0033] When in use: first, install the mounting base 1 on the automotive interior ceiling bonding machine to achieve preliminary installation. After the installation is completed, when the hot riveting assembly needs to be turned over, first turn on the rotating cylinder 2. The operation of the rotating cylinder 2 can drive the coupling 3 to rotate. The coupling 3 can also drive the shaft 4 to rotate. Since the shaft 4 is connected to the connecting arm 5, the shaft 4 can drive the connecting arm 5 to turn while rotating, so that the connecting arm 5 can drive the hot riveting assembly to turn over. After the hot riveting assembly is turned into place, the shaft 4 is locked and positioned by the limiter 6 to ensure that the shaft 4 will not drive the connecting arm 5 to rotate. The output end of the movable latch cylinder 7 drives the latch rod 8 to move to one side, so that the latch rod 8 will gradually extend to the inner cavity of the connecting arm 5, thereby realizing the positioning of the connecting arm 5, ensuring its stability after flipping, and preventing displacement and the like during the later riveting process, so as to realize the flipping operation. When hot riveting operation is required, the movement range of the spring mechanism 11 and the pre-pressing block 12 is adjusted by the stroke adjustment screw 13 according to the actual situation. During the adjustment process, the spring mechanism 11 and the pre-pressing block 12 will slide along the guide rail 17, and then the spring mechanism 11 and the pre-pressing block 12 can be adjusted by the guide rail 17. The position is limited to prevent misalignment, and then the reset force of the spring mechanism 11 can drive the pre-pressing block 12 to press the surrounding area that needs to be riveted. After the pressing is completed, the riveting block 10 is heated by the dry-burning heater inside the riveting block 10, so that the riveting block 10 gradually heats up. While heating up, the heat on the surface of the riveting block 10 will be transferred to the material, so that the material is heated and softened, and the output end of the riveting cylinder 9 drives the riveting block 10 and the softened material to contact with the base material, thereby realizing the hot riveting operation. After the hot riveting operation is completed, the output end of the brake latch cylinder 7 drives the latch rod 8 to gradually separate from the inner cavity of the connecting arm 5, and by rotating The nut, due to the threaded connection between the nut and the screw, will gradually move upward while rotating and disengage from the limit block, thereby causing the limit block to lose pressure and its inner cavity to gradually expand, giving the shaft rod 4 sufficient space for movement, thereby releasing the limit on the shaft rod 4. After that, the coupling 3 and the shaft rod 4 are driven to rotate by rotating the cylinder 2, and the shaft rod 4 drives the connecting arm 5 and the hot riveting assembly to flip, so that the hot riveting assembly can be flipped and reset to the initial position for the next use. This application can not only ensure the efficiency and quality of hot riveting by flipping the hot riveting assembly, but also meet the hot riveting needs of various interior ceiling products.
