[0002] Press riveting is a crucial step in achieving a secure connection between sheet metal and nuts, and it is widely used in the production of components in industries such as automobile manufacturing, aerospace, and electronic equipment. In traditional press riveting operations, operators need to hold a single press nut, align it with a pre-drilled hole in the sheet metal, and then use a press to complete the pressing and fixing process.

[0003] This operating mode has significant limitations. When multiple sets of riveting operations are required on the same sheet metal, workers need to frequently grab and position the nuts, which not only increases hand fatigue but also easily leads to nut misalignment due to unstable hand grip, affecting riveting accuracy. Especially in mass production scenarios, production efficiency is difficult to improve. Therefore, we need to provide a sheet metal riveting device for sheet metal processing. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5 This utility model provides a technical solution: a sheet metal riveting device for sheet metal processing, comprising:

[0024] Tooling table 1, punch 2 and placement mechanism 3. The punch 2 is fixed on the top of tooling table 1 and the placement mechanism 3 is installed inside tooling table 1. The placement mechanism 3 is used to position and place multiple press-fit nuts.

[0025] The placement mechanism 3 includes a column 31, a support rod 32, a support cylinder 33, and a positioning component 34. The column 31 is rotatably installed in the tooling table 1, and multiple support rods 32 are evenly distributed on its surface. Support cylinders 33 are fixedly installed at the outer ends of the multiple support rods 32. The positioning component 34 is installed in the tooling table 1 and is located below the stamper 2. It is used to position the support cylinder 33 below the stamper 2 so that the stamper 2 can press the top rivet nut of the support cylinder 33 into the hole in the metal plate.

[0026] Specifically, the placement mechanism 3 can position multiple rivet nuts at once, providing precise positioning during subsequent riveting operations with pre-set holes in the sheet metal. This allows for pre-positioning of multiple nuts, ensuring accurate placement of multiple rivet nuts in one operation, reducing manual intervention and the labor intensity of operators. It also avoids positioning deviations caused by hand operation, improving riveting consistency. Through the cooperation of the positioning component 34 and the support cylinder 33, it ensures that each nut to be riveted is in a preset position when rotated under the stamper 2, achieving high-precision alignment with the holes in the sheet metal, effectively controlling riveting errors, and ensuring connection strength and stability.

[0027] A positioning ring 4, which works in conjunction with the positioning component 34, is fixedly installed on the surface of the support cylinder 33.

[0028] Furthermore, the positioning ring 4 is made of 45 steel, and its lower edge is welded and fixed to the outer wall of the support cylinder 33. When the support cylinder 33 rotates to the bottom of the stamper 2, the lower edge of the positioning ring 4 forms a surface contact with the top of the arc-shaped clamp 341. The radial limit of the support cylinder 33 is achieved through the rigid metal contact, which avoids the support cylinder 33 from swaying during the riveting process, solves the problem of the nut being offset by force during the riveting process, and improves the coaxiality of the riveting.

[0029] The positioning component 34 includes an arc-shaped clamp 341, a pusher 342, and a groove 343. The groove 343 is opened in the tooling table 1, and the pusher 342 is slidably installed inside. The top of the pusher 342 is fixedly installed with an arc-shaped clamp 341 that is compatible with the support cylinder 33, and the arc-shaped clamp 341 is used in conjunction with the positioning ring 4.

[0030] Specifically, the arc-shaped clamp 341 is made of alloy cast iron, and its inner arc surface is in clearance fit with the outer wall of the support cylinder 33; the push seat 342 is fixedly connected to the arc-shaped clamp 341, and the part of the bottom of the push seat 342 embedded in the groove 343 is provided with a wear-resistant liner; when the push seat 342 slides in the groove 343, the arc-shaped clamp 341 axially positions the support cylinder 33, and together with the positioning ring 4, it forms a two-way positioning system, which solves the problem of insufficient stability of the single positioning method.

[0031] It also includes an elastic element 5 for pushing the push seat 342. The elastic element 5 includes a spring 51 and a slide rod 52. The slide rod 52 is fixed in the groove 343 and its surface is slidably installed in the push seat 342. The spring 51 is installed between the groove 343 and the push seat 342 and is movably sleeved on the surface of the slide rod 52.

[0032] It is worth noting that the slide bar 52 is made of chrome-plated round steel, and its two ends are welded and fixed to the side wall of the groove 343. The corresponding position of the push seat 342 is provided with a linear bearing that cooperates with the slide bar 52. The spring 51 is made of carbon spring steel. In its natural state, it pushes the push seat 342 to keep the arc-shaped clamp 341 in contact with the support cylinder 33. The elastic element 5 is guided by the slide bar 52 to ensure the linear movement of the push seat 342. The elastic force of the spring 51 ensures that the arc-shaped clamp 341 always has a preload, which solves the problem of the positioning element 34 not resetting in time and ensures the consistency of positioning during continuous operation.

[0033] A protective plate 6 is fixedly installed inside the groove 343. The protective plate 6 is located on top of the spring 51, and the surface of the protective plate 6 is slidably installed inside the push base 342.

[0034] It should be noted that the guard plate 6 is made of stainless steel and is fixed in the middle of the groove 343. There is a gap between the lower surface of the guard plate 6 and the top of the spring 51, and the surface slides in contact with the bottom of the push seat 342. The guard plate 6 can prevent processing debris from falling into the area of ​​the spring 51, and at the same time provide auxiliary support for the push seat 342, which solves the problem that the spring 51 is easily stuck by foreign objects and extends the service life of the elastic element 5.

[0035] The bottom of the tank 343 is sloping and extends through one side of the tooling table 1. The push seat 342 has a hook 8 installed on one side through the baffle 7.

[0036] Specifically, one end of the baffle 7 is fixedly connected to the push base 342, and the other end is hooked by the hook 8; the slope angle of the trough 343 is 15-30 degrees, and a dust collection trough can be provided at the lowest point; the slope structure enables the self-discharge of debris, which solves the problem of difficult cleaning of dust inside the equipment and improves the convenience of maintenance.

[0037] The top of the support cylinder 33 is provided with a positioning groove 9 for placing the rivet nut, and the tooling table 1 is provided with a slot 10 for use with the placement cylinder.

[0038] The inner wall of the positioning groove 9 is provided with a rubber anti-slip layer, and the groove depth is adapted to the height of the rivet nut; the trough 10 corresponds to the movement trajectory of the support cylinder 33. The positioning groove 9 prevents the nut from accidentally falling off through the anti-slip layer. The trough 10 and the support cylinder 33 work together to realize the directional discharge of processing debris, which solves the problems of unstable nut placement and internal equipment cleanliness.

[0039] The stamping device 2 involved in this application is implemented using existing mature technology and is connected to an external PLC controller and power supply. This is a conventional technical means in this field, so its specific circuit connection, control logic and working process will not be described in detail.

[0040] The device first places the rivet nuts to be riveted one by one into the positioning groove 9 at the top of the support cylinder 33, with the embossed surface of the rivet nuts facing upwards. Then, the work hook 8 drives the pusher 342 to move. The pusher 342 slides in the groove 343 and stretches the spring 51. At this time, the column 31 is rotated, rotating the support cylinder 33 to one side of the arc-shaped clamp 341. Then, the pull on the hook 8 is released. Under the action of the spring 51, the arc-shaped clamp 341 positions the support cylinder 33. At the same time, the bottom of the arc-shaped clamp 341 is in contact with the top of the tooling table 1, and the top is in contact with the bottom of the positioning ring 4 on the surface of the support cylinder 33, thus achieving support for the support cylinder 33. Place the hole on the surface of the sheet metal into the embossed surface of the top of the rivet nut. The embossed surface protrusion and the inner hole of the sheet metal are initially positioned. Start the punch 2. The bottom of the contact head of the punch 2 is open, so that the rivet nut is fixed on the sheet metal. At this time, pull the hook 8 again to remove the empty support cylinder 33. The support cylinder 33 with the rivet nut is rotated to the side of the arc clamp 341 for further processing. A guard plate 6 is provided to protect the spring 51, and the baffle 7 can cover the top of the groove 343 to reduce dust falling. The bottom of the groove 343 is inclined to facilitate dust discharge. A drain trough 10 is provided on the tooling table 1 to facilitate the discharge of dust from the support cylinder 33.
