[0002] The integration of electronic products is getting higher and higher, and the dimensions of modular electronic products are getting smaller and smaller. In order to facilitate the production, processing and assembly of modular products, their main structure is generally designed into a cavity or frame shape. In order to facilitate the installation of modular products in chassis equipment, the positioning pins will be installed on the main body of the module using the riveting process. The conventional pin riveting method is to install the pin into the reserved hole of the riveted part and then press it against the lower die.

The column 34 is used to support the pad column spring 33, and the pad column spring 33 presses against the pad column boss 32 so that it can move up and down synchronously during the riveting process. The upper end of the pad column boss 32 is the workpiece support surface, where the pad column boss 32 is slightly higher than the lower die boss 22, and directly presses against the workpiece to be riveted. The riveting lower die 2 and the balance pad column 3 are respectively located on both sides of the support platform device 5 to keep the workpiece balanced during the riveting process.

[0046] The clamping device 4 includes a clamping block 41, a clamping plate 42, a clamping spring 43, a clamping slider 44 and a clamping column 45. The other parts other than the clamping block 41 constitute the clamping mechanism. Two clamping blocks 41 are located at the front and rear, and a clamping plate 42 is located in the middle. The clamping block 41 is connected to the clamping slider 44 through the clamping column 45. The clamping slider 44 is located in the front and rear slide grooves of the clamping plate 42. A clamping spring 43 is provided between the clamping slider 44 and the clamping plate 42 to support inward.

[0047] First, place the clamping slider 44 and the clamping spring 43 in the front and rear slide grooves (square grooves) reserved in the clamping plate 42. The threaded end of the clamping column 45 passes through the clamping spring 43 and is fastened to the threaded hole reserved in the clamping slider 44. The threaded hole end passes through the clamping plate 42 and the corresponding reserved holes of the clamping block 41, and the clamping column 45 is fastened to the clamping block 41 with screws. The clamping block 41 is divided into left and right, and the fastening hole positions are slightly different. During the riveting process, the clamping block 41 contacts the front and back of the workpiece to be riveted to limit its forward and backward movement. The spring not only facilitates the adjustment of the front and rear installation positions of the workpiece to be riveted before riveting, but also enables the riveting of modular products of different thicknesses through this device.

[0048] The inner clamping surface of the clamping block 41 is provided with an isosceles trapezoidal protrusion, and the outer clamping surface of the clamping plate 42 is provided with an isosceles trapezoidal groove matching with the protrusion to meet the clamping matching of a workpiece to be riveted with a specific shape.

The fastening column 53 is fastened to the clamping plate 42 with screws. The clamping plate 42 is also divided into left and right, and the fastening hole positions are different. Before riveting, the riveting lower die 2 and the balance pad column 3 need to be placed in the corresponding reserved holes of the support platform. During the riveting process, the spring here makes the clamping plate 42 contact with the two sides of the workpiece to be riveted to limit the left and right movement of the workpiece. Similarly, the spring is convenient for adjusting the left and right installation positions of the workpiece to be riveted before riveting, and it can also realize riveting of module products of different widths through this device.

[0058] Place the pin washer on the washer support surface of the lower die boss 22 of the flip riveting lower die 2, pass the conical top of the flip riveting punch 24 of the flip riveting lower die 2 through the middle hole of the pin washer, and pass the bottom of the pin through the reserved hole of the workpiece to be flip riveted. Pull open the clamping device 4 and the clamping mechanism, clamp the workpiece to be flip riveted above the flip riveting lower die 2, the clamping device 4 and the clamping plate 42 of the clamping mechanism limit the left and right sides of the workpiece, and the clamping block 41 limits the front and back of the workpiece, so that the workpiece to be flip riveted is placed on the flip riveting device and the pin is kept in a vertical state.

[0059] The conical top of the riveting punch 24 contacts the pin, and the lower die boss 22 makes the pin washer close to the inner surface of the workpiece to be riveted under the action of the lower die spring 23. The pad boss 32 of the balancing pad column 3 directly presses against the inner surface of the workpiece to be riveted under the action of the pad column spring 33.

[0060] Press the switch of the electronic press, the upper die 1 of the riveting presses down the pin, and the conical top impact of the riveting punch 24 causes the pin to deform, and the deformed part simultaneously rivets the pin washer to the inner surface of the workpiece to be riveted, completing the pin riveting. When riveting for the first time, the pressure value of the electronic press can be adjusted to a suitable parameter according to the riveting effect.

[0061] Pull open the clamping device and the clamping mechanism, remove the workpiece (frame) that has been riveted, replace the unriveted workpiece to be riveted according to the above steps, and complete the riveting again.
