The positioning fixture 2 is displaced along the front and rear directions on the workbench 1 through a first driving member 3, and the feeding mechanism 6 includes a first feeding component 601 and a second feeding component 602. The first feeding component 601 and the second feeding component 602 are installed in the mounting frame 4 and above the positioning fixture 2 through a support plate 5. The first feeding component 601 and the second feeding component 602 have the same structure, and the first feeding component 601 and the second feeding component 602 are both used to extend and convey the nuts to the corresponding riveting stations.

[0017] The first feeding assembly 601 includes a first cylinder 601-1 and a first feeding plate 601-2. The first cylinder 601-1 is fixed on the support plate 5. A first slide rail 601-4 is provided below the first feeding plate. A first slider 501 is correspondingly installed above the support plate 5. The first slider 501 slides in the first slide rail 601-4. The first cylinder 601-1 drives the first feeding plate 601-2 to move back and forth. The first feeding plate 601-2 is provided with a plurality of placement grooves 601-2-1 for placing nuts. In the standby state, the first feeding assembly 601 and the second feeding assembly 602 extend to the outside of the riveting punch to facilitate the operator to place the nuts in the placement grooves 601-2-1. The placement grooves 601-2-1 are provided with guide columns 601-3 for positioning the placed nuts.

[0018] The riveting mechanism 7 includes a second cylinder 701, a first riveting assembly 703, a second riveting assembly 704 and an elastic pressing rod 706. The second cylinder 701 is fixed above the mounting frame 4. The first riveting assembly 703 and the second riveting assembly 704 have the same structure and are both installed on the driving plate 702. The first riveting assembly 703 and the second riveting assembly 704 are arranged side by side. The second cylinder 701 is driven and installed with the driving plate 702. The first riveting assembly 703 includes a first mounting block 703-1 and several first riveting punches 703-2. The first riveting punch 703-2 is vertically installed below the first mounting block 703-1 and perpendicular to the positioning fixture 2. The first mounting block 703-1 is fixed on the driving plate 702. A vacuum adsorption hole is provided at the bottom end of the first riveting punch 703-2. The second riveting assembly 704 includes a second mounting block and a second riveting punch. The length of the second riveting punch is less than that of the first riveting punch 703-2.

[0019] The elastic pressing rod 706 is between the first riveting assembly 703 and the second riveting assembly 704 and is fixed to the driving plate 702 through the limit block 705. The elastic pressing rod 706 and the first riveting punch 703-2 are parallel to each other.

[0020] The elastic pressing rod 706 includes a main rod body 706-1, the top end of the main rod body 706-1 is vertically fixed on the limit block 705, and the bottom end of the main rod body 706-1 is installed with a limit ring 706-2. The main rod body 706-1 is also provided with a compression spring 706-3. The compression spring 706-3 is squeezed between the limit ring 706-2 and the limit block 705. The limit ring 706-2 is below the first riveting punch 703-2. When the riveting operation is performed, the limit ring 706-2 first contacts the product to press and position it.

[0021] The positioning fixture 2 includes a positioning base plate 201 and several positioning platforms 202 and positioning pins 203 installed on the positioning base plate 201.

The first driving member 3 is fixed on the workbench 1 and driven by the positioning base plate 201. A second slider 204 is installed under the positioning base plate 201, and a second slide rail 101 is installed on the workbench 1 to match the position of the second slider 204.

[0022] Operation process: The injection molded part to be riveted is positioned on the positioning plate through the positioning table 202 and the positioning pin 203, and then the nuts are placed in the first feeding assembly 601 and the second feeding assembly 602 respectively. The start button of the equipment is activated, and the first feeding assembly 601 and the second feeding assembly 602 are moved to the set position. At the same time, the positioning fixture 2 is also moved to the bottom of the riveting mechanism 7. After the first riveting assembly 703 and the second riveting assembly 704 correspondingly adsorb the nuts, the first feeding assembly 601 and the second feeding assembly 602 retreat away from the first riveting assembly 703, and the second cylinder 701 drives the first riveting assembly 703 and the second riveting assembly 704 to press down synchronously. At the same time, the elastic positioning rod contacts the product before the nut is squeezed to press and position the product, ensuring that the first riveting assembly 703 and the second riveting assembly 704 can operate accurately and stably. After the riveting is completed, the first riveting assembly 703 and the second riveting assembly 704 are reset, and the positioning fixture 2 is pushed to the outside. The processed product is taken out and a new product is placed, and the operation is repeated in this cycle.
