[0026] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0027] Example:

[0028] As attached Figure 1 To be continued Figure 3 As shown:

[0029] This utility model provides a hot pressing device for automotive door lock components, including a mounting frame 1. The surface of the mounting frame 1 is equipped with a fixing mechanism 2 and a hot riveting welding mechanism 3. The fixing mechanism 2 includes a first mounting plate 201 mounted on the surface of the mounting frame 1. A set of hollow placement racks 202 are mounted on the top of the first mounting plate 201. It also includes a set of first cylinders 203 mounted on the top of the first mounting plate 201. A clamping block 204 is mounted on the output end of the first cylinder 203. The surface of the clamping block 204 is provided with a groove. A feeding mechanism 4 is mounted on the surface of the first mounting plate 201.

[0030] The feeding mechanism 4 includes a connector 401 mounted on the surface of the first mounting plate 201. A second cylinder 402 is mounted on one end of the connector 401. A push plate 403 is mounted on the output end of the second cylinder 402. One side of the push plate 403 is in contact with the placement rack 202.

[0031] By using the mounting frame 1, the first mounting plate 201, the placement frame 202, the first cylinder 203, the clamping block 204, the connector 401, the second cylinder 402, and the push plate 403 in conjunction, the buckle is first placed between the two clamping blocks 204, and then the first cylinder 203 is activated to clamp the buckle. The groove on the surface of the clamping block 204 matches the buckle. Then, the base plate is placed on the placement frame 202, and the hole in the base plate passes through the buckle. Then, the hot riveting welding mechanism 3 is activated to perform hot pressing welding. After the welding is completed, the hot riveting welding mechanism 3 and the fixing mechanism 2 are reset. Then, the second cylinder 402 is activated, which drives the push plate 403 to move, thereby pushing out the part located on the placement frame 202. Through the above design, the hot pressing welded part can be removed without manual handling, which improves practicality.

[0032] The hot riveting welding mechanism 3 includes a second mounting plate 301 mounted on the mounting frame 1. An electric cylinder 302 is mounted on the top of the second mounting plate 301. A connecting plate 303 is mounted through the output end of the electric cylinder 302 through the second mounting plate 301. A hot riveting welding head 304 is mounted on the surface of the connecting plate 303.

[0033] With the coordinated use of the second mounting plate 301, electric cylinder 302, connecting plate 303, and hot riveting welding head 304, when the buckle and base plate are installed, the electric cylinder 302 can be activated. When the electric cylinder 302 is activated, it will drive the connecting plate 303 to move. The movement of the connecting plate 303 will drive the hot riveting welding head 304 to move, thereby welding the buckle and base plate. It should be noted that the hot riveting welding head 304 is matched with the buckle.

[0034] The clamping block 204 is detachably connected to the output end of the first cylinder 203, and the hot riveting welding head 304 is detachably connected to the connecting plate 303.

[0035] The above design allows for quick replacement of the clamping block 204 and the hot riveting welding head 304, enabling hot pressing welding of buckles and base plates of different sizes.

[0036] The first mounting plate 201 has a guide slide 5 installed on its surface, and a collection box 6 is provided below the guide slide 5.

[0037] By using the guide slide 5 and the collection box 6, the parts pushed off by the push plate 403 will fall into the guide slide 5 and then into the collection box 6.

[0038] The mounting bracket 1 has a limiting mechanism 7 installed on its surface.

[0039] The limiting mechanism 7 includes mounting boxes 701 installed on both sides of the mounting frame 1. A straight groove 702 is formed on the surface of the mounting box 701, and the straight groove 702 extends into the mounting box 701. A limiting rod 703 is installed inside the mounting box 701. A protrusion 704 is installed on the surface of the limiting rod 703, and the protrusion 704 extends through the straight groove 702 to the outside.
