[0002] Self-piercing riveting equipment is a widely used joining technology in industrial manufacturing, especially in the fields of automotive manufacturing, aerospace and electronics. This equipment can rivet two or more metal materials together by pressure without pre-punching holes, and has the advantages of high efficiency, environmental protection and high strength.

[0003] The Chinese patent CN217595804U authorized and announced on October 18, 2022 discloses a lightweight self-piercing riveting device for automobiles, which includes a workbench, on the upper end of which is fixedly provided a product fixing mechanism, a coil fixing mechanism, an automatic feeding mechanism and a riveting mechanism.

[0009] Preferably, one end of the chain away from the first sprocket is assembled at the outer side position of the second sprocket. When the first sprocket rotates, the second sprocket can rotate accordingly.

[0010] Preferably, the sliding block is located inside the fixed seat and is in a sliding connection state with the fixed seat. The sliding block can slide relative to the fixed seat.

[0011] Preferably, an auxiliary stabilizing component is arranged on the side of the conveying mechanism. The auxiliary stabilizing component includes a second hydraulic chamber. A ratchet is drivingly connected to the side of the first force-bearing gear. A fixing plate is assembled on the side of the conveying mechanism. The fixing plate is connected to a force-bearing plate. A ratchet pawl is fixedly connected to the side of the force-bearing plate. One end of the second hydraulic chamber is slidably connected to a force-bearing rod. The other end of the second hydraulic chamber is slidably connected to a push rod.

[0012] Preferably, there are two first springs in total, and the two first springs are symmetrically distributed with respect to the ratchet pawl. The force on the ratchet pawl from the first springs is more uniform.

[0013] Preferably, the ratchet pawl is located at the side position of the ratchet and is in an engaged state with the ratchet. The ratchet pawl can limit the rotation direction of the ratchet.

[0014] Preferably, a cleaning component is arranged on the side of the conveying mechanism. The cleaning component includes a third hydraulic chamber. A liquid pump is assembled on the top of the fixed frame. A pipeline is assembled on the side of the liquid pump. One end of the third hydraulic chamber is slidably connected to a connecting rod. The other end of the third hydraulic chamber is slidably connected to an arc-shaped rod. A through rotating shaft is rotatably connected inside the pipeline. A connecting plate is fixedly connected to the side of the rotating shaft. A blocking block is fixedly connected to the bottom of the rotating shaft.

[0015] Preferably, the connecting rod is located at the top position of the force-bearing rod and is in a fixed state with the force-bearing rod. When the force-bearing rod moves, the connecting rod can move accordingly.

[0016] The present invention provides a self-piercing riveting device, which has the following beneficial effects:

[0017] (1) For this self-piercing riveting device, when the micro motor is started, it drives the driving gear to rotate, causing the driving gear to drive the first force-bearing gear to rotate, and the first force-bearing gear drives the power rod to rotate for conveying the material. When the material is transported to the bottom position of the self-piercing riveting seat, the electric push rod is started to drive the self-piercing riveting seat to move downward. The self-piercing riveting seat drives the hydraulic rod to move downward, and in cooperation with the first hydraulic chamber, drives the moving seat to move. When the self-piercing riveting seat moves to the material and is ready for riveting operation, the driving gear drives the second force-bearing gear to rotate, causing the second force-bearing gear to drive the torsion spring rod to rotate. The torsion spring rod drives the first sprocket to rotate, and in cooperation with the chain, causes the second sprocket to rotate. The second sprocket drives the lead screw to rotate, causing the sliding block to drive the limiting plate to approach the auxiliary limiting plate to clamp the material for riveting operation, improving the stability of the device during riveting operation.

[0018] (2) For this self-piercing riveting device, when the first force-bearing gear drives the power rod to rotate clockwise, the power rod drives the ratchet to rotate clockwise. The ratchet squeezes the pawl, causing the pawl to stretch the first spring and move, ensuring that the ratchet can rotate clockwise successfully. When the moving seat moves, that is, when the material needs to be riveted, the moving seat squeezes the force-bearing rod, causing the force-bearing rod to move. In cooperation with the second hydraulic chamber, it drives the push rod to move and squeeze the force-bearing plate, thereby squeezing the pawl and restricting the pawl in a state of being closely attached to the ratchet. In this way, it is difficult for the power rod without power to continue rotating under the action of inertia. At the same time, due to the setting of the ratchet and the pawl, when riveting operation is carried out, the material on the conveying mechanism will not move to the left, making the device more stable during riveting operation.

[0019] (3) For this self-piercing riveting device, after the device is enabled, the liquid pump is synchronously enabled to convey the cleaning liquid into the pipeline assembled on the side of the liquid pump. When the self-piercing riveting seat moves downward, the force-bearing rod moves to the side synchronously, causing the force-bearing rod to drive the connecting rod to move to the side. In cooperation with the third hydraulic chamber, it drives the arc rod to move, causing the arc rod to drive the connecting plate to rotate. The connecting plate drives the rotating shaft to rotate, causing the rotating shaft to drive the blocking block to rotate. After rotation, the blocking block closes the originally open pipeline, and at this time, the cleaning liquid cannot be sprayed out through the pipeline and the nozzle. When the device completes one riveting operation, the force-bearing rod resets. Similarly, the blocking block resets. At this time, the cleaning liquid can be sprayed out to flush the material debris generated during the riveting operation from the conveying mechanism, completing the cleaning of the conveying mechanism and reducing the use of the cleaning liquid, improving the usability of the device.

[0035] Embodiment 1

[0036] Please refer to Figures 1-4 , a self-piercing riveting device, including a conveying mechanism 100 and a fixing frame 200. An electric push rod 300 is assembled on the top of the fixing frame 200. The bottom of the electric push rod 300 is drivingly connected to a self-piercing riveting seat 400. The side of the conveying mechanism 100 is drivingly connected to a power rod 500;

[0037] A stabilizing assembly 600 is assembled between the conveying mechanism 100 and the fixing frame 200. The stabilizing assembly 600 includes a first hydraulic chamber 601. One end of the first hydraulic chamber 601 is slidably connected to a hydraulic rod 602. The hydraulic rod 602 is located on the side of the self-piercing riveting seat 400 and is assembled on the self-piercing riveting seat 400. The other end of the first hydraulic chamber 601 is slidably connected to a moving seat 603. A micro motor 604 is assembled on the top of the moving seat 603. The side of the micro motor 604 is drivingly connected to a power gear 605. A first stress gear 606 is fixedly connected to the side of the power rod 500. Starting the micro motor 604, Figure 3 as shown in the perspective view in

[0038] A torsion spring rod 607 is rotatably connected to the side of the conveying mechanism 100. A second force-bearing gear 608 and a first sprocket 609 are fixedly connected to the outer side of the torsion spring rod 607 respectively. When materials are transported to the bottom position of the self-piercing riveting seat 400, they are detected by the laser detector on the self-piercing riveting seat 400, thereby starting the electric push rod 300, driving the self-piercing riveting seat 400 connected to it in transmission to move downward. The self-piercing riveting seat 400 simultaneously drives the hydraulic rod 602 assembled on it to move downward, cooperating with the first hydraulic chamber 601 slidably connected to the hydraulic rod 602, so that the pressure in the first hydraulic chamber 601 decreases, driving the moving seat 603 slidably connected to the first hydraulic chamber 601 to move towards the side close to the first hydraulic chamber 601. At this time, the micro motor 604 and the driving gear 605 assembled on the moving seat 603 move towards the side close to the second force-bearing gear 608 together.

[0039] A chain 610 is assembled on the outer side of the first sprocket 609. A fixed seat 611 is assembled on the side of the conveying mechanism 100. A through lead screw 612 is rotatably connected inside the fixed seat 611. A second sprocket 613 is fixedly connected to the outer side of the lead screw 612. One end of the chain 610 away from the first sprocket 609 is assembled at the outer side position of the second sprocket 613. A sliding block 614 is connected to the outer side of the lead screw 612 through thread setting. The sliding block 614 is located inside the fixed seat 611 and is in a sliding connection state with the fixed seat 611. A limiting plate 615 is fixedly connected to the top of the sliding block 614. An auxiliary limiting plate 616 is assembled inside the fixed frame 200. When the self-piercing riveting seat 400 moves to the position of the materials and is ready to perform corresponding riveting operations, the driving gear 605 moves to the position of the second force-bearing gear 608 and drives the second force-bearing gear 608 to rotate clockwise, so that the second force-bearing gear 608 drives the torsion spring rod 607 fixedly connected to it to rotate clockwise. The torsion spring rod 607 drives the first sprocket 609 fixedly connected to it to rotate. Cooperating with the chain 610 assembled on the first sprocket 609, the second sprocket 613 driven by the chain 610 in transmission with the first sprocket 609 rotates synchronously clockwise. The second sprocket 613 drives the lead screw 612 fixedly connected to it to rotate. Since the sliding block 614 assembled on the lead screw 612 is restricted by the fixed seat 611 slidably connected to it, the sliding block 614 moves in the horizontal direction, driving the limiting plate 615 fixedly connected to the sliding block 614 to move towards the side close to the auxiliary limiting plate 616 to clamp the materials for riveting operations. In this way, it can be ensured that during the riveting operation, the conveying mechanism 100 is in a stopped state and the materials are in a clamped state, making the entire self-piercing riveting process more stable.

[0040] After the self-piercing riveting operation is completed, the self-piercing riveting seat 400 is reset. Similarly, the micro-motor 604 and the power gear 605 are reset. The second force-bearing gear 608 loses the restriction of the power gear 605 and can rotate reversely under the action of the torsion spring rod 607 fixedly connected thereto for reset. Similarly, the limit plate 615 is reset to cancel the clamping of the material. The reset power gear 605 meshes with the first force-bearing gear 606 again, thereby driving the material on the conveying mechanism 100 to perform corresponding transportation operations. At this time, the device returns to the initial transportation state, facilitating the riveting operation of the next piece of material and improving the usability of the device.

[0041] During use, start the micro-motor 604 to Figure 3As shown in the middle perspective, it can drive the power gear 605 connected to it in transmission to rotate counterclockwise, so that the power gear 605 drives the force-bearing gear one 606 engaged with it to rotate clockwise, and the force-bearing gear one 606 drives the power rod 500 fixedly connected to it to rotate clockwise, so that the power rod 500 drives the conveying mechanism 100 connected to it in transmission to perform corresponding conveying operations on the materials located on the conveying mechanism 100; when a material is transported to the bottom position of the self-piercing riveting seat 400, it is detected by the laser detector on the self-piercing riveting seat 400, thereby starting the electric push rod 300 to drive the self-piercing riveting seat 400 connected to it in transmission to move downward. The self-piercing riveting seat 400 simultaneously drives the hydraulic rod 602 assembled on it to move downward, cooperating with the hydraulic chamber one 601 slidably connected to the hydraulic rod 602, so that the pressure in the hydraulic chamber one 601 decreases, driving the moving seat 603 slidably connected to the hydraulic chamber one 601 to move toward the side close to the hydraulic chamber one 601. At this time, the micro motor 604 and the power gear 605 assembled on the moving seat 603 move together toward the side close to the force-bearing gear two 608. When the self-piercing riveting seat 400 moves to the material and is ready to perform corresponding riveting operations, the power gear 605 moves to the force-bearing gear two 608 and drives the force-bearing gear two 608 to rotate clockwise, so that the force-bearing gear two 608 drives the torsion spring rod 607 fixedly connected to it to rotate clockwise, and the torsion spring rod 607 drives the sprocket one 609 fixedly connected to it to rotate. Cooperating with the chain 610 assembled on the sprocket one 609, the sprocket two 613 connected to the sprocket one 609 in transmission through the chain 610 rotates synchronously clockwise. The sprocket two 613 drives the lead screw 612 fixedly connected to it to rotate. Since the sliding block 614 assembled on the lead screw 612 is restricted by the fixed seat 611 slidably connected to it, the sliding block 614 moves in the horizontal direction, driving the limiting plate 615 fixedly connected to the sliding block 614 to move toward the side close to the auxiliary limiting plate 616 to clamp the material for riveting operations; after the self-piercing riveting operation is completed, the self-piercing riveting seat 400 is reset. Similarly, the micro motor 604 and the power gear 605 are reset. The force-bearing gear two 608 loses the restriction of the power gear 605 and can rotate reversely under the action of the torsion spring rod 607 fixedly connected to it for reset. Similarly, the limiting plate 615 is reset to cancel the clamping of the material; and the reset power gear 605 meshes with the force-bearing gear one 606 again, thereby driving the materials on the conveying mechanism 100 to perform corresponding transportation operations.

[0042] Embodiment 2

[0043] Please refer to Figures 1-6On the basis of the first embodiment, an auxiliary stabilizing assembly 700 is provided on the side of the conveying mechanism 100. The auxiliary stabilizing assembly 700 includes a hydraulic chamber 2 701. The side of the force-bearing gear 1 606 is connected to a ratchet 702 in a transmission manner. The side of the conveying mechanism 100 is equipped with a fixed plate 703. The side of the fixed plate 703 is connected to a force-bearing plate 705 by setting a spring 1 704. The side of the force-bearing plate 705 is fixedly connected to a pawl 706. There are two springs 1 704 in total. The two springs 1 704 are symmetrically distributed about the pawl 706. The pawl 706 is located on the side of the ratchet 702 and is in a meshing state with the ratchet 702. Figure 3 As shown in the middle perspective, when the force-bearing gear 1 606 drives the power rod 500 to rotate clockwise, the power rod 500 drives the ratchet 702 fixedly connected thereto to rotate clockwise synchronously, and the ratchet 702 rotating clockwise can squeeze the pawl 706, so that the pawl 706 moves to the side away from the ratchet 702 through the force-bearing plate 705 fixedly connected thereto to stretch the spring 1 704, thereby ensuring that the ratchet 702 can successfully rotate clockwise. In this way, it can be ensured that the setting of the ratchet 702 and the pawl 706 will not affect the use of the stabilizing assembly 600.

[0044] One end of the hydraulic chamber 701 is slidably connected to a force rod 707 , and the other end of the hydraulic chamber 701 is slidably connected to a push rod 708 . A spring 709 is mounted on the side of the force rod 707 . When the moving seat 603 moves to the side close to the hydraulic bin 1 601, that is, when the material needs to be riveted, the moving seat 603 squeezes the force rod 707, so that the force rod 707 moves to the side close to the hydraulic bin 2 701, and cooperates with the hydraulic bin 2 701 slidably connected to the force rod 707, so that the pressure in the hydraulic bin 2 701 increases, and drives the push rod 708 slidably connected to the hydraulic bin 2 701 to move. At this time, the push rod 708 moves to the side close to the force plate 705, squeezes the force plate 705, and squeezes the ratchet 706 through the force plate 705 and the spring 1 704, and limits the ratchet 706 to a state of close fit with the ratchet 702. In this way, it is difficult for the power rod 500 that loses power to continue to rotate under the action of inertia. At the same time, due to the setting of the ratchet 702 and the ratchet 706, when the riveting operation is performed, the material on the conveying mechanism 100 will not move to the left. This makes the device more stable when performing riveting operations.

[0045] When the movable seat 603 is reset, the force rod 707 loses its restriction, and the force rod 707 can be reset under the action of the second spring 709, so that the power rod 500 can be restored to a state where it can rotate clockwise. At this time, the auxiliary stabilizing assembly 700 is completely reset to facilitate the next activation of the assembly.

[0046] When used, based on the first embodiment,Figure 3 As shown in the middle view, when the driving gear 606 drives the power rod 500 to rotate clockwise, the power rod 500 drives the ratchet wheel 702 fixedly connected thereto to rotate clockwise synchronously. The ratchet wheel 702 rotating clockwise can squeeze the pawl 706, so that the pawl 706 moves to the side away from the ratchet wheel 702 by stretching the first spring 704 through the force-bearing plate 705 fixedly connected thereto, thus ensuring that the ratchet wheel 702 can rotate clockwise successfully. When the moving seat 603 moves towards the side close to the first hydraulic chamber 601, that is, when riveting operation needs to be performed on the material, the moving seat 603 squeezes the force-bearing rod 707, so that the force-bearing rod 707 moves towards the side close to the second hydraulic chamber 701. Cooperating with the second hydraulic chamber 701 slidably connected to the force-bearing rod 707, the pressure in the second hydraulic chamber 701 increases, driving the push rod 708 slidably connected to the second hydraulic chamber 701 to move. At this time, the push rod 708 moves towards the side close to the force-bearing plate 705, squeezes the force-bearing plate 705, and squeezes the pawl 706 through the force-bearing plate 705 and the first spring 704, restricting the pawl 706 in a state of being in close contact with the ratchet wheel 702. In this way, it is difficult for the power rod 500 without power to continue rotating under the action of inertia. At the same time, due to the setting of the ratchet wheel 702 and the pawl 706, when the riveting operation is performed, the material on the conveying mechanism 100 will not move to the left either; when the moving seat 603 resets, the force-bearing rod 707 loses the restriction, and the force-bearing rod 707 can reset under the action of the second spring 709, so that the power rod 500 returns to the state where it can rotate clockwise again.

[0047] Embodiment 3

[0048] Please refer to Figures 1-8 , on the basis of Embodiment 1 and Embodiment 2, a cleaning assembly 800 is arranged on the side of the conveying mechanism 100. The cleaning assembly 800 includes a third hydraulic chamber 801. A liquid pump 802 is assembled on the top of the fixing frame 200. A pipeline 803 is assembled on the side of the liquid pump 802. One end of the third hydraulic chamber 801 is slidably connected with a connecting rod 804. The connecting rod 804 is located at the top of the force-bearing rod 707 and is fixed with the force-bearing rod 707. After the device is enabled, the liquid pump 802 is synchronously enabled to convey the cleaning liquid into the pipeline 803 assembled on the side of the liquid pump 802. When the piercing riveting seat 400 moves downward, the force-bearing rod 707 moves sideways synchronously, so that the force-bearing rod 707 drives the connecting rod 804 fixedly connected thereto to move towards the side close to the third hydraulic chamber 801. Cooperating with the third hydraulic chamber 801 slidably connected to the connecting rod 804, the pressure in the third hydraulic chamber 801 increases.

[0049] At the other end of the third hydraulic chamber 801, an arc-shaped rod 805 is slidably connected. Inside the pipe 803, a penetrating rotating shaft 806 is rotatably connected. On the side surface of the rotating shaft 806, a connecting plate 807 is fixedly connected. At the bottom of the rotating shaft 806, a blocking block 808 is fixedly connected. A spray head 809 is assembled on the side surface of the pipe 803. When the pressure in the third hydraulic chamber 801 increases, it can drive the movement of the arc-shaped rod 805 slidably connected to the third hydraulic chamber 801, causing the arc-shaped rod 805 to drive the connecting plate 807 fixedly connected thereto to rotate. The connecting plate 807 drives the rotating shaft 806 fixedly connected thereto to rotate, causing the rotating shaft 806 to drive the blocking block 808 fixedly connected thereto to rotate. After the rotation of the blocking block 808, the originally open pipe 803 is closed. At this time, the cleaning liquid cannot be sprayed out through the pipe 803 and the spray head 809, further maintaining the stability of the device during the riveting operation. When the device completes a riveting operation, the force-bearing rod 707 resets. Similarly, the blocking block 808 resets. At this time, the cleaning liquid can be sprayed out, flushing the material debris generated during the riveting operation from the conveying mechanism 100. That is, the cleaning of the conveying mechanism 100 is completed, and the use of the cleaning liquid is reduced, improving the usability of the device.

[0050] During use, on the basis of Embodiment 1 and Embodiment 2, after the device is enabled, the liquid pump 802 is synchronously enabled to convey the cleaning liquid into the pipe 803 assembled on the side surface of the liquid pump 802. When the self-piercing riveting seat 400 moves downward, the force-bearing rod 707 moves synchronously to the side, causing the force-bearing rod 707 to drive the connecting rod 804 fixedly connected thereto to move toward the side close to the third hydraulic chamber 801. Cooperating with the third hydraulic chamber 801 slidably connected to the connecting rod 804, the pressure in the third hydraulic chamber 801 increases, driving the movement of the arc-shaped rod 805 slidably connected to the third hydraulic chamber 801, causing the arc-shaped rod 805 to drive the connecting plate 807 fixedly connected thereto to rotate. The connecting plate 807 drives the rotating shaft 806 fixedly connected thereto to rotate, causing the rotating shaft 806 to drive the blocking block 808 fixedly connected thereto to rotate. After the rotation of the blocking block 808, the originally open pipe 803 is closed. At this time, the cleaning liquid cannot be sprayed out through the pipe 803 and the spray head 809. When the device completes a riveting operation, the force-bearing rod 707 resets. Similarly, the blocking block 808 resets. At this time, the cleaning liquid can be sprayed out, flushing the material debris generated during the riveting operation from the conveying mechanism 100.
