[0048] A height adjustment bracket 4, with an external thread provided at one end, and the height adjustment bracket 4 is adapted to be threadedly connected to the second installation hole of the hot riveting bracket 1 through its external thread;

[0049] The other end of the height adjustment bracket 4 is provided with a threaded installation hole;

[0050] The hot riveting welding head 5 is threadedly connected to the threaded mounting hole at the other end of the height adjustment bracket 4;

[0051] The cold air blowing pipe 6 is fixed to the hot riveting bracket 1 by a pipe clamp fixing member 8;

[0052] The cold air blowing pipe 6 is of a hollow structure and the two ends are internally connected. One end of the cold air blowing pipe 6 is adapted to be connected to a gas source, and the other end is provided with cold air blowing holes facing the position where the hot riveting welding head 5 is located.

[0053] In this embodiment, as Figures 1-2 shown, first, the heating rod 2 is installed in the first installation groove of the hot riveting bracket 1 and fixed by the first limit fixing member 3. Then, by rotating the height adjustment bracket 4, precise adjustment of the height of the hot riveting welding head 5 is achieved. Finally, the cold air blowing pipe 6 is fixed to the hot riveting bracket 1 by the pipe clamp fixing member 8, and air is blown through the cold air blowing holes towards the hot riveting welding head 5 to effectively cool the hot riveting welding head 5.

[0054] Specifically, as Figures 1-2 shown, the hot riveting welding device further includes a second limit fixing member 7;

[0055] A radial threaded hole communicating with the second installation hole is provided on the outer surface of the hot riveting bracket 1;

[0056] The second limit fixing member 7 is of a bolt structure, and an external thread matching the radial threaded hole is provided on its outer surface;

[0057] When the height adjustment bracket 4 is installed on the hot riveting bracket 1, the second limit fixing member 7 is adapted to be threadedly connected to the radial threaded hole and pass through the hot riveting bracket 1 to abut against the outer surface of the height adjustment bracket 4 to limit the axial position of the height adjustment bracket 4.

[0058] In this embodiment, as Figures 1-2 shown, the second limit fixing member 7 realizes the fixation of the axial position of the height adjustment bracket 4 by providing a radial threaded hole communicating with the second installation hole on the outer surface of the hot riveting bracket 1 and combining with the second limit fixing member 7 of the bolt structure.

[0059] In addition, an anti-loosening design such as a spring washer or self-locking thread can be considered to be added to the second limit fixing member 7 to ensure stability under long-term use or vibration environment.

[0060] Specifically, as Figures 1-2 shown, the pipe clamp fixing member 8 is provided with a threaded connection end and a clamping end, where:

[0061] The threaded connection end is provided with an external thread, and the clamping end is provided with an annular clamping structure, and the annular clamping structure is provided with an adjustment notch;

[0065] In this embodiment, as Figures 1-2 shown, the pipe clamp fixing member 8 takes into account both installation convenience and adjustment flexibility. The double-end design of the threaded connection end and the clamping end enables the pipe clamp fixing member 8 to simultaneously achieve a firm connection with the hot riveting bracket 1 and a reliable clamping of the cold air blowing pipe 6. The external thread of the threaded connection end matches the mounting hole on the hot riveting bracket 1, ensuring the firmness and stability of the connection, and at the same time facilitating the installation and disassembly operations.

[0070] The hot riveting welding fixing assembly 92 is provided with an electromagnetic adsorption device, and the electromagnetic adsorption device is adapted to generate a magnetic force and magnetically cooperate with the hot riveting bracket connection assembly 91.

[0071] Specifically, as Figures 3-5 shown, the hot riveting bracket connection assembly 91 is further provided with a circumferential rotation limiting guide groove 913, and the hot riveting welding fixing assembly 92 is provided with a circumferential rotation limiting guide protrusion 923 that cooperates with the circumferential rotation limiting guide groove 913.

[0073] Specifically, as Figure 3 and Figure 5 shown, a wire passing hole 912 is further provided on the hot riveting bracket connection assembly 91, and the wire passing hole 912 communicates with the heating rod avoidance groove 911.

[0074] In this embodiment, as Figures 1-5 shown, the composite connection mechanism improves the installation convenience and use flexibility of the hot riveting welding device. The three-section arc-shaped frame design of the hot riveting bracket connection assembly 91 enables it to be stably sleeved outside the hot riveting bracket 1, and at the same time, the abutment of the upper end of the hot riveting bracket 1 against the inner bottom surface of the arc-shaped frame further enhances the connection stability. The electromagnetic adsorption device on the hot riveting welding fixing assembly 92 provides the possibility of quick installation and disassembly. The operator only needs to control the switch of the electromagnetic adsorption device to complete the installation or disassembly of the hot riveting welding device, greatly improving the work efficiency. The three-section arc-shaped frame can be fixed by welding or by screws.

[0075] The design of the circumferential rotation limiting guide groove 913 and the circumferential rotation limiting guide protrusion 923 effectively prevents the hot riveting welding device from rotating during use, ensuring the accuracy of the welding position. The setting of the heating rod avoidance groove 911 takes into account the space requirements of the heating rod 2, avoiding interference problems during installation. The design of the wire passing hole 912 facilitates the arrangement of the temperature sensor cable, making the installation of the temperature sensor cable more concise and orderly.

[0076] Specifically, as Figures 1-2 shown, the hot riveting welding device further includes a controller 10 and a temperature sensor;

[0077] The temperature sensor is disposed in contact with the hot riveting bracket 1 or the hot riveting head 5;

[0078] The controller 10 is respectively connected to the temperature sensor and the heating rod 2. The temperature sensor is adapted to detect the temperature of the hot riveting bracket 1 or the hot riveting head 5 and send a temperature signal to the controller;

[0079] The controller 10 is adapted to control the heating of the heating rod 2 according to the temperature signal.

[0080] In this embodiment, as Figures 1-2As shown, the fitting arrangement of the temperature sensor with the hot riveting bracket 1 ensures the accuracy of temperature detection and provides reliable real-time temperature data for the controller 10. The controller 10 is provided with a maximum set temperature and a minimum set temperature. When the controller 10 detects that the temperature signal of the temperature sensor is higher than the maximum set temperature, the controller 10 controls the heating rod 2 to stop heating. When the temperature is lower than the minimum set temperature, the heating is controlled to start. The controller 10 can be a PLC. The controller 10 controls the heating rod 2 by controlling the switching power supply of the heating rod 2. The temperature sensor can also be arranged in contact with the hot riveting head 5.
