[0022] In order to better understand the purpose, structure and function of the present invention, the following is a further detailed description of the automatic riveting mechanism for hollow rivets of the present invention in conjunction with the accompanying drawings.

[0023] like Figure 1As shown, the hollow rivet automatic riveting mechanism of the present invention includes a riveting platform 2, the bottom of the riveting platform 2 is movably connected to a rotating motor 21, the bottom of the riveting platform 2 is fixedly connected to a first bracket 8, the top of the riveting platform 2 is movably connected to a stepping motor 22, the top of the stepping motor 22 is fixedly connected to a guide shaft 18, a downward pressure cylinder 3 is provided on the top of the guide shaft 18, a pressure block 4 is provided at the bottom of the downward pressure cylinder 3, one end of a slide 19 is provided on the side of the downward pressure cylinder 3, and the other end of the slide 19 is fixedly connected to one end of a vibration plate 20. The product is placed in the fixture of the rotating platform manually, and then the rotating motor is rotated. 21 transfers the jig to the riveting position of the automatic riveting machine. There is a stepper motor 22 under the product. Through high-precision rotation, the rivets of the product are aligned with the rivet position. The riveting machine automatically sends the rivets through the vibration plate. The rivets pass through the slide 19 and are transferred to the top of the product. The downward pressure cylinder 3 automatically presses the rivet into the product. After completing one riveting, the product stepper motor 22 automatically rotates ninety degrees to rivet the next one. Repeat the action four times in sequence. The product riveting is completed, and the rotating platform transfers the second product to the riveting position. This cycle automatically completes the four riveting points of the product, greatly improving efficiency and saving manpower.

[0024] The bottom of the riveting platform 2 is provided with an outer plate 16, and the bottom of the outer plate 16 is fixedly connected with a fixed foot support 17. By providing the outer plate 16 and the fixed foot support 17 at the bottom of the riveting platform 2, the platform can be stably fixed on the plane to prevent position deviation during operation, which may cause problems in the riveting of hollow rivets, and the stabilization effect is better.

[0025] A second bracket 9 is provided on the back of the outer plate 16, and an auxiliary fixing block 12 is fixedly connected to the side of the second bracket 9. By cooperating with the second bracket 9 and the auxiliary fixing block 12, the riveter can be fixed to prevent the riveter from being unable to accurately transport rivets due to vibration, and the temperature effect is better.

[0026] A longitudinal base plate 5 is provided on the top of the second bracket 9, a pad 15 is fixedly connected to the top of the longitudinal base plate 5, a first adjustment plate 10 is movably connected to the back of the longitudinal base plate 5, and a second adjustment plate 11 is fixedly connected to the front of the first adjustment plate 10. The initial position of the riveting machine can be adjusted by the first adjustment plate 10 and the second adjustment plate 11. In this way, when the riveting machine is put into use for the first time or when the equipment is replaced, the adjustment plate can be used to adjust so that the downward pressure cylinder 3 can be completely aligned with the equipment on the top of the riveting platform 2, and the adjustment is more convenient.

[0027] The top of the downward-pressing cylinder 3 is movably connected to a cylinder mounting plate 6, and a combination plate 1 is provided on the top of the cylinder mounting plate 6. A guard plate 13 is fixedly connected to the side of the combination plate 1, and an induction lamp bracket 14 is fixedly connected to the bottom of the guard plate 13. Since the top of the downward-pressing cylinder 3 is fixedly connected to the cylinder mounting plate 6, when the cylinder needs to be replaced, the cylinder mounting plate 6 can be removed and replaced with a new downward-pressing cylinder 3, and the replacement is relatively convenient.

[0028] A lower die assembly 7 is provided on the back of the outer plate 16. By providing the lower die assembly 7 on the outer plate 16, the riveted parts can be removed from the cylinder surface when the riveting process is completed, so that they can be returned to the equipment of the riveting platform 2, and the removal process is relatively simple.

[0029] The working principle of the automatic riveting mechanism for hollow rivets: When using this automatic riveting mechanism for hollow rivets, first, it is necessary to use the outer plate 16 and the fixed foot support 17 provided at the bottom of the riveting platform 2 to stably fix the platform on the plane to prevent position deviation during operation, which causes problems in the riveting of hollow rivets. The stability effect is good. Then, the riveting machine can be fixed by cooperating with the second bracket 9 and the auxiliary fixing block 12 to prevent the riveting machine from being unable to accurately transport rivets due to vibration. The temperature effect is good. After the assembly is completed, it can be put into use. The initial position of the riveting machine can be adjusted by the first adjusting plate 10 and the second adjusting plate 11. In this way, when the riveting machine is put into use for the first time or when the equipment is replaced, the adjusting plate can be used to adjust so that the downward pressure cylinder 3 can be completely aligned with the equipment on the top of the riveting platform 2. The adjustment is relatively convenient. The product is manually placed in the jig of the rotating platform, and then the rotating motor 21 transmits the jig to the automatic riveting machine. At the riveting position of the machine, there is a stepper motor 22 under the product. Through high-precision rotation, the rivets of the product are aligned with the rivet position. The riveting machine automatically feeds the rivets through the vibration plate. The rivets pass through the slide 19 and are transmitted to the top of the product. The pressing cylinder 3 automatically presses the rivet into the product. After completing a riveting, the product stepper motor 22 automatically rotates ninety degrees and rivets the next one. Repeat the action and rivet four times in sequence. The product riveting is completed, and the rotating platform transmits the second product to the riveting position. In this way, the four riveting points of the product are automatically completed, which greatly improves efficiency and saves manpower. At the same time, the cylinder mounting plate 6 is fixedly connected to the top of the pressing cylinder 3. When the cylinder needs to be replaced, the cylinder mounting plate 6 can be removed and replaced with a new pressing cylinder 3. The replacement is more convenient. Then, through the lower die assembly 7 provided on the peripheral plate 16, the riveted parts can be removed from the cylinder surface when the riveting process is completed so that they can be returned to the equipment of the riveting platform 2. The unloading process is relatively simple.
