DETAILED DESCRIPTION

[0021] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention.

[0022] like Figure 1-3 As shown, a breeze hot riveting device is characterized in that it includes:

[0023] A base 1, wherein the base 1 has a sliding seat 101;

[0024] The carrier 104 is fixed on the sliding seat 101 of the base 1 and the carrier 104 can move in the Y-axis direction on the sliding seat 101;

[0025] A gantry mechanism, on which a hot and cold riveting assembly is installed, and the hot and cold riveting assembly can move in the X and Z axes on the gantry mechanism;

[0026] The product 2 is mounted on the carrier 104 , and a carrier plate 102 connected to the sliding seat 101 is provided below the carrier 104 .

[0027] Furthermore, the gantry mechanism includes a column 3 vertically fixed on the base 1, an X-axis movable seat 302 fixed above the column 3, and a Z-axis movable seat 303 installed on the X-axis movable seat 302, and a mounting seat 305 for installing hot and cold riveting components is installed on one side of the Z-axis movable seat 303.

[0028] Furthermore, the cold and hot riveting assembly includes a cold riveting head 306 , a hot riveting head 307 and a nozzle 308 . The cold riveting head 306 is parallel to the hot riveting head 307 and is installed on the mounting base 305 with the output end facing downward. The nozzle 308 is installed at the output end of the hot riveting head 307 .

[0029] Furthermore, the lowermost end of the cold rivet head 306 is slightly lower than the lowermost end of the hot rivet head 307 .
