[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Refer to Figure 1 - Figure 4 As shown in the figure, an embodiment provided by the present utility model: A PCB riveting fixture includes a carrying body 1. A support seat 2 is fixedly connected to the upper surface of the carrying body 1. A slide block 9 is slidably connected to the outer wall of the support seat 2. A connecting piece 10 is fixedly connected to the lower surface of the slide block 9. A riveting die 5 is fixedly connected to the lower surface of the connecting piece 10. A product ZIF 6 is arranged inside the riveting die 5. A slide rod 11 is fixedly connected to the upper surface of the carrying body 1. A positioning plate 3 is slidably connected to the top of the slide rod 11. A product body 4 is arranged inside the positioning plate 3. A ZIF fixing plate 14 is arranged on the lower surface of the product body 4. An ejecting assembly is arranged on the lower surface of the ZIF fixing plate 14. The ejecting assembly is used to push the ZIF fixing plate 14 to move. The ejecting assembly includes an ejector pin 7. The top of the ejector pin 7 is in contact with the lower surface of the ZIF fixing plate 14. The lower surface of the ejector pin 7 is fixedly connected to an ejector pin seat 13. The lower surface of the ejector pin seat 13 is fixedly connected to the upper surface of the carrying body 1. The ejector pins 7 are arranged in a rectangular array above the carrying body 1. A slide plate 12 is slidably connected inside the carrying body 1. The slide plate 12 is arranged on the outer wall of the ejector pins 7. The slide plate 12 is arranged below the product body 4. The upper surface of the slide plate 12 is fixedly connected to the lower surface of the positioning plate 3. The slide plate 12 is arranged on the outer wall of the ejector pin seat 13;

[0025] Specifically, first place the product ZIF6 inside the riveting die 5 to position the product ZIF6. Then insert the product body 4 into the sliding groove on the inner wall of the positioning plate 3 to position the product body 4. Next, drive the handle 8 to rotate on the outer wall of the support base 2, apply pressure to the slider 9 through the rod body of the handle 8, so that the slider 9 slides on the outer wall of the support base 2. Then drive the connecting piece 10 to move through the movement of the slider 9. Next, drive the riveting die 5 and the product ZIF6 to move downward through the connecting piece 10, so that the product ZIF6 is attached to the product body 4. At the same time, push the product body 4 to move downward. Then drive the positioning plate 3 to move downward through the movement of the product body 4, so that the positioning plate 3 slides on the outer wall of the sliding rod 11. At the same time, the movement of the positioning plate 3 will also drive the sliding plate 12 to slide inside the carrying body 1, so that the ejector pin 7 moves out of the inside of the sliding plate 12. At this time, the ejector pin 7 pushes the ZIF fixing plate 14 to support the product body 4. Due to the support of the ZIF fixing plate 14, the product ZIF6 is inserted into the product body 4, thus realizing riveting.

[0026] Refer to Figure 1 - Figure 3 A handle 8 is rotatably connected to the outer wall of the support base 2. The handle 8 is in contact with and riveted to the slider 9. The riveting die 5 is arranged above the product body 4, and the product ZIF6 is arranged above the product body 4.

[0027] Specifically, during the riveting process, first position the product ZIF6 and the product body 4, and then drive the handle 8 to realize riveting. The operation is convenient and easy to use.

[0028] Working principle: When the PCB riveting fixture is needed, first place the product ZIF6 inside the riveting die 5, insert the product body 4 into the sliding groove of the positioning plate 3 to achieve precise positioning. Then drive the handle 8 to apply pressure to the slider 9, so that the slider 9 slides. The movement of the slider 9 drives the connecting piece 10, and then drives the riveting die 5 and the product ZIF6 to move downward, so that the product ZIF6 is closely attached to the product body 4. While the product ZIF6 is attached to the product body 4, the product body 4 continues to move downward. This movement also drives the positioning plate 3 to move downward. The positioning plate 3 slides on the outer wall of the sliding rod 11. The movement of the positioning plate 3 also drives the sliding plate 12 to slide inside the carrying body 1, so that the ejector pin 7 moves out of the inside of the sliding plate 12. The movement of the ejector pin 7 enables the ZIF fixing plate 14 to support the product body 4, so that the product ZIF6 can be smoothly inserted into the product body 4 to complete the riveting process.

[0029] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
