Description

Technical Field

[0001] The utility model relates to the technical field of riveting equipment, in particular to a riveting and clamping device for a side anti-collision reinforcement plate. Background Art

[0002] With the increasing demand for lightweight vehicles, lightweight materials such as aluminum alloys and high-strength steel are increasingly being used in automotive body structures. Because these dissimilar materials are difficult to reliably join using traditional welding processes, self-pierce riveting (SPR) technology has become a key joining process in the automotive industry due to its excellent connection performance, environmental friendliness, and applicability.

[0003] Currently, automotive side impact reinforcements, as critical safety components, typically utilize a composite structure of aluminum alloy and steel to achieve both lightweight and high strength. In actual production, the riveting of these dissimilar composite components primarily relies on manual placement of the workpiece on a fixture, followed by a robot performing self-pierce riveting. This entire process requires ensuring the relative positional accuracy and stability of the workpieces.

[0004] For example, Chinese patent CN220239836U discloses a riveting clamping device, including a workbench, a support column, a force-bearing platform, two clamping assemblies, two buffer assemblies, a riveting assembly and a moving unit, wherein the moving unit includes a threaded rod, a drive motor, a support plate and a moving block, and the moving block has a threaded hole, which can quickly move the support column, thereby reducing the workload of the staff. However, the above-mentioned riveting clamping device has many shortcomings in the process of specific application: the main manifestations are that the positioning stability of the workpiece is difficult to ensure, the clamping process is time-consuming and labor-intensive, the workpiece is prone to deformation, and the riveting space is limited. These problems not only affect product quality and production efficiency, but also increase the labor intensity of the operator; especially when connecting dissimilar materials such as side anti-collision reinforcement plates, due to the large differences in material properties in the composite structure of aluminum alloy and steel, higher requirements are placed on the clamping and positioning of the workpiece.

[0005] Currently, no effective solutions have been proposed for the problems in related technologies. Utility Model Content

[0009] Furthermore, in order to ensure that the first mounting frame and the second mounting frame can firmly support the first riveting clamping assembly and the second riveting clamping assembly, and provide reliable structural strength guarantee during the riveting process, the first mounting frame includes an L-shaped vertical plate arranged on the top of the workbench, a triangular rib is arranged on one side of the L-shaped vertical plate, and a plurality of fixing bolts are arranged at the bottom end of the L-shaped vertical plate through the workbench.

[0010] Furthermore, in order to cooperate with the first riveting clamping assembly to achieve bidirectional positioning and clamping of the side anti-collision reinforcement plate, and provide stable tooling guarantee for the subsequent riveting process, the second riveting clamping assembly includes a second mounting vertical plate arranged at one end of the top of the second mounting frame, a second circular fixed top cover is arranged on one side of the bottom of the second mounting vertical plate, and a second adjusting bolt is arranged on one side of the second circular fixed top cover through the second mounting vertical plate, a second cylinder is arranged at the bottom end of the second circular fixed top cover, a second circular mounting bottom cover is arranged at the bottom end of the second cylinder, a second connecting piece is arranged at the top of the output end of the second cylinder, a zigzag rotating arm is arranged through the middle of the second connecting piece, and second connecting blocks cooperating with the top of the second mounting vertical plate are arranged on both sides of one end of the zigzag rotating arm, and a U-shaped pressing block is fixedly arranged at the other end of the zigzag rotating arm.

[0022] To further illustrate each embodiment, the present invention provides drawings, which are part of the disclosure of the present invention and are mainly used to illustrate the embodiments. They can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. By referring to these contents, ordinary technicians in this field should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0023] According to an embodiment of the present utility model, a riveting and clamping device for a side anti-collision reinforcement plate is provided.

[0024] The present invention will now be further described with reference to the accompanying drawings and specific embodiments. Figure 1-Figure 4 As shown, the side anti-collision reinforcement plate riveting clamping device according to the embodiment of the utility model includes a workbench 1 (in addition, in specific applications, a control panel is provided on one side of the workbench 1, and the first cylinder 504 and the second cylinder 704 are electrically connected in sequence through the control panel. This is the prior art and will not be elaborated on here). A square movable frame 2 is provided at the bottom end of the workbench 1, and movable wheels 3 are provided at both ends of the bottom end of the square movable frame 2. A plurality of equidistantly arranged first mounting frames 4 are provided at the top of the workbench 1, and a first riveting clamping assembly 5 is fixedly provided at one end of the top of the first mounting frame 4. A second mounting frame 6 connected to the workbench 1 is symmetrically provided on one side of the first mounting frame 4, and the first mounting frame 4 has the same structure as the second mounting frame 6. A second riveting clamping assembly 7 that cooperates with the first riveting clamping assembly 5 is fixedly provided at one end of the top of the second mounting frame 6.

[0025] In addition, in specific applications, a rivet gun is provided between the first mounting frame 4 and the second mounting frame 6, and the side anti-collision reinforcement plate 8 to be riveted is placed between the Z-shaped supporting block 509 and the U-shaped pressing block 709. The Z-shaped supporting block 509 and the U-shaped pressing block 709 can be replaced according to the different surface shapes of the side anti-collision reinforcement plate 8.

[0026] In one embodiment, for the above-mentioned first mounting frame 4 and second mounting frame 6, the first mounting frame 4 includes an L-shaped vertical plate 401 arranged at the top of the workbench 1, and a triangular rib 402 is fixedly provided on one side of the L-shaped vertical plate 401, and a plurality of fixing bolts 403 are provided at the bottom end of the L-shaped vertical plate 401 passing through the workbench 1, so that the first mounting frame 4 and the second mounting frame 6 can firmly support the first riveting clamping assembly 5 and the second riveting clamping assembly 7, and provide reliable structural strength guarantee during the riveting process.

[0027] The operating principle of the first and second mounting brackets 4 and 6 is as follows: an L-shaped vertical plate 401 is secured to the workbench 1 via several fixing bolts 403 at its bottom, ensuring a secure connection between the entire mounting bracket structure and the workbench 1. Triangular ribs 402 on one side of the L-shaped vertical plate 401 provide reinforcement and support, effectively preventing deformation or shaking of the L-shaped vertical plate 401 caused by the pressure generated by the first riveting clamping assembly 5 during the riveting process, thereby ensuring the accuracy and stability of the riveting process. This structural design ensures the mounting bracket's robustness while facilitating disassembly and maintenance when necessary.

[0028] The first mounting frame 4 and the second mounting frame 6 have the same structure and operate in the same principle. Because the first mounting frame 4 and the second mounting frame 6 are symmetrically arranged, this design ensures that the first riveting clamping assembly 5 and the second riveting clamping assembly 7 on either side can cooperate with each other. At the same time, the symmetrical design of the first mounting frame 4 and the second mounting frame 6 reserves sufficient operating space for the riveting gun, which can operate between the first mounting frame 4 and the second mounting frame 6, facilitating the loading and unloading and riveting operations of the side anti-collision reinforcement plate 8. The supporting role of the triangular rib 402 is particularly important because the actual riveting process generates large forces, requiring sufficient structural strength to ensure the stability of the entire device.

[0029] In one embodiment, for the above-mentioned first riveting clamping assembly 5, the first riveting clamping assembly 5 includes a first mounting vertical plate 501 arranged at one end of the top of the first mounting frame 4 (in addition, in specific applications, the first mounting frame 4 and the first mounting vertical plate 501 are fixedly connected by a plurality of bolts), a first circular fixed top cover 502 is provided on one side of the bottom of the first mounting vertical plate 501, and a first adjusting bolt 503 is provided on one side of the first circular fixed top cover 502 passing through the first mounting vertical plate 501, a first cylinder 504 is provided at the bottom end of the first circular fixed top cover 502, a first circular mounting bottom cover 505 is provided at the bottom end of the first cylinder 504, a first connecting member 506 is provided at the top of the output end of the first cylinder 504 (in addition, in specific applications, the first connecting member 506 is connected to the X-shaped rotating arm 507 by a pin shaft), and the center of the first connecting member 506 The part is provided with an I-shaped rotating arm 507, and both sides of one end of the I-shaped rotating arm 507 are provided with a first connecting block 508 that cooperates with the top of the first mounting vertical plate 501 (in addition, in specific applications, the first connecting block 508, the first mounting vertical plate 501 and the I-shaped rotating arm 507 are connected by a pin shaft), and a Z-shaped supporting block 509 is fixedly provided on one side of the other end of the I-shaped rotating arm 507 (in addition, in specific applications, the Z-shaped supporting block 509 is made of elastic material, and the Z-shaped supporting block 509 and the I-shaped rotating arm 507 are connected by a number of bolts), and the cross-section of the Z-shaped supporting block 509 is a right-angle bending structure, so that the linear motion of the first cylinder 504 can be converted into a swinging motion with a larger stroke of the I-shaped rotating arm 507 by utilizing the lever principle, and cooperate with the second riveting clamping assembly 7 to achieve stable clamping of the side anti-collision reinforcement plate 8.

[0030] The working principle of the first riveting clamping assembly 5 is as follows: when riveting operation is required, the first cylinder 504 moves telescopically under the control of the control panel, and the output end of the first cylinder 504 drives the "X"-shaped rotating arm 507 to rotate around the pin connected to the first connecting block 508 through the first connecting member 506. The "X"-shaped rotating arm 507 forms a lever structure. The lever principle can be used to convert the linear motion of the cylinder into a swinging motion with a larger stroke, thereby driving the Z-shaped supporting block 509 at the other end to move up and down, cooperating with the U-shaped pressing block of the second riveting clamping assembly 7. Block 709 precisely clamps the side anti-collision reinforcement plate 8. This lever structure design not only increases the clamping stroke, but also provides a greater clamping torque. At the same time, the first circular fixed top cover 502 and the first circular mounting bottom cover 505 constitute a stable support structure of the cylinder. The installation angle of the first cylinder 504 can be precisely adjusted through the first adjusting bolt 503 to ensure that the Z-shaped support block 509 can achieve the best fit with the surface of the side anti-collision reinforcement plate 8. In addition, the Z-shaped support block 509 made of elastic material can prevent damage to the workpiece surface during the clamping process.

[0031] In one embodiment, for the above-mentioned second riveting clamping assembly 7, the second riveting clamping assembly 7 includes a second mounting plate 701 arranged at one end of the top of the second mounting frame 6 (in addition, in specific applications, the second mounting frame 6 and the second mounting plate 701 are fixedly connected by a plurality of bolts), a second circular fixed top cover 702 is provided on one side of the bottom of the second mounting plate 701, and a second adjusting bolt 703 is provided on one side of the second circular fixed top cover 702 passing through the second mounting plate 701, a second cylinder 704 is provided at the bottom end of the second circular fixed top cover 702, a second circular mounting bottom cover 705 is provided at the bottom end of the second cylinder 704, and a second connecting member 706 is provided at the top of the output end of the second cylinder 704 (in addition, in specific applications, the second connecting member 706 is in a zigzag pattern with the second connecting member 706). The rotating arm 707 is connected by a pin shaft), a zigzag rotating arm 707 is provided through the middle of the second connecting member 706, and both sides of one end of the zigzag rotating arm 707 are provided with a second connecting block 708 that cooperates with the top of the second mounting vertical plate 701 (in addition, in specific applications, the second connecting block 708, the second mounting vertical plate 701 and the zigzag rotating arm 707 are connected by a pin shaft), and a U-shaped pressing block 709 is fixedly provided at the other end of the zigzag rotating arm 707 (in addition, in specific applications, the U-shaped pressing block 709 is made of elastic material, and the U-shaped pressing block 709 is connected to the zigzag rotating arm 707 by a number of bolts), thereby cooperating with the first riveting clamping assembly 5 to realize bidirectional positioning and clamping of the side anti-collision reinforcement plate 8, providing stable tooling guarantee for the subsequent riveting process.

[0032] When the second connecting member 706 is pushed upward by the second cylinder 704, the zigzag rotating arm 707 is connected with the second connecting block 708 as a fulcrum, and the linear motion of the second cylinder 704 is converted into the pressing action of the U-shaped pressing block 709 by the lever principle, thereby forming a complementary fit with the first riveting clamping assembly 5. When the U-shaped pressing block 709 moves downward, it forms a clamping force with the Z-shaped supporting block 509 to ensure that the side anti-collision reinforcement plate 8 is firmly positioned. At the same time, the U-shaped pressing block 709 is designed with elastic material, which can avoid scratching the surface of the side anti-collision reinforcement plate 8 while ensuring the clamping force.

[0033] In order to facilitate understanding of the above technical solutions of the present invention, the working principle or operation method of the present invention in actual process is described in detail below.

[0034] In actual application, first place the side anti-collision reinforcement plate 8 to be riveted on the Z-shaped supporting block 509, start the first cylinder 504 and the second cylinder 704 through the control panel, the first cylinder 504 drives the "X"-shaped rotating arm 507 to swing upward, so that the Z-shaped supporting block 509 holds up the workpiece, and at the same time the second cylinder 704 pushes the zigzag rotating arm 707 to move downward, so that the U-shaped pressing block 709 presses the workpiece; the riveting clamping assemblies on both sides firmly position the side anti-collision reinforcement plate 8 through the clamping force generated by the lever principle, and the riveting gun can now perform riveting operations in the space between the first mounting bracket 4 and the second mounting bracket 6; after the riveting is completed, the first cylinder 504 and the second cylinder 704 are reset to release the workpiece, and the operator can take out the riveted side anti-collision reinforcement plate 8, and put in the next side anti-collision reinforcement plate 8 to be riveted, and repeat the above operation.
