Description

Technical Field

[0001] This utility model relates to the field of automotive assembly technology, specifically to a multi-functional integrated device for testing, riveting, and marking automotive crossbeams. Background Technology

[0002] Currently, reducing vehicle weight and fuel consumption are key to manufacturers' competitiveness in the automotive industry. As a crucial component, automotive crossbeams are made from low-density, high-ductility aluminum profiles, resulting in significant weight reduction. However, aluminum profiles also have relatively low hardness and strength, necessitating heat treatment processes to improve their properties. After solution hardening, the strength and hardness of aluminum profiles increase significantly over time—a phenomenon known as aging. Aging is a complex process; the electrical conductivity of aluminum profiles changes after aging, and conductivity can be used to assess the aging status. Only after passing aging tests can automotive crossbeams proceed to riveting and marking processes.

[0003] Chinese patent CN110711947A provides a rivet nut inspection device with integrated laser marking. This device integrates a laser marking unit, allowing for simultaneous inspection and marking with a single manual button press, saving time. However, this device lacks aging detection and riveting functions. Existing technologies for aging detection and riveting of automotive crossbeam aluminum profiles require multiple steps. Aging detection involves manually testing the conductivity of the product using a handheld eddy current conductivity meter. This manual inspection requires numerous actions from the operator, is susceptible to various factors, and involves high workload, making it difficult to guarantee accurate results and resulting in low production efficiency. Furthermore, the riveting and marking processes for automotive crossbeams require various processing equipment, leading to numerous assembly steps and a large footprint. Therefore, a multi-functional integrated device for inspecting, riveting, and marking automotive crossbeams is needed. Utility Model Content

[0027] like Figures 1 to 7 The illustrated multi-functional integrated equipment for inspecting, riveting, and marking automotive crossbeams includes a frame 1 and an aging detection mechanism 2, a riveting mechanism 3, and a marking mechanism 4, all controlled by an electronic control system 5. The frame 1 comprises a fixedly connected upper frame 1-1 and a lower frame 1-2. The riveting mechanism 3 is located on top of the lower frame 1-2 and in front of the upper frame 1-1. The electronic control system 5 is located within the upper frame 1-1, allowing the operator to easily view data from the electronic control system 5 while the riveting mechanism 3 is in operation. The riveting mechanism 3 includes a rotatable worktable 3-1 for fixing the riveted workpiece. The detection contacts of the aging detection mechanism 2 and the printing needles of the marking mechanism 4 are integrated onto the worktable 3-1. The worktable 3-1 has three riveting positions that can rotate counterclockwise by 90°, 180°, and 270°, facilitating multi-directional riveting operations on the workpiece. After the operator completes the riveting, the worktable 3-1 is reset clockwise by pressing the start button.

[0028] One end of the worktable 3-1 is equipped with a drive shaft seat 3-2, and the other end is equipped with a support shaft seat 3-3. The drive shaft seat 3-2 and the support shaft seat 3-3 are located on the same axis. The drive shaft seat 3-2 is electrically connected to the electrical control system 5. The electrical control system 5 can drive the worktable 3-1 to rotate circumferentially. The worktable 3-1 has three counterclockwise rotation riveting positions in the working state. When resetting, the worktable 3-1 rotates clockwise to return to a horizontal state. Figure 2As shown, the workbench 3-1 includes a fixed plate 3-1-1. Above the fixed plate 3-1-1 are positioning blocks 3-1-2, clamping devices 3-1-3, and sensors 3-1-4. Multiple positioning blocks 3-1-2 are symmetrically arranged on the fixed plate 3-1-1. The positioning blocks 3-1-2 are arranged to fit the shape of the riveted workpiece for positioning it. Multiple clamping devices 3-1-3 are located on one side of the positioning blocks 3-1-2. The clamping devices 3-1-3 can move vertically to press or release the riveted workpiece onto the fixed plate 3-1-1. The sensor 3-1-4 is located in the middle of the fixed plate 3-1-1 to detect whether the riveted workpiece is properly positioned. Figure 3 and Figure 5 The clamping device 3-1-3 includes a clamping cylinder 3-1-3a, a valve module 3-1-3b, and an air source 3-1-3c. The clamping cylinder 3-1-3a is connected to the air source 3-1-3c through the valve module 3-1-3b. Multiple clamping cylinders 3-1-3a are symmetrically fixed on the fixing plate 3-1-1 to clamp the riveted workpiece. The valve module 3-1-3b and the air source 3-1-3c are fixed in the lower frame 1-2. The valve module 3-1-3b and the sensor 3-1-4 are both electrically connected to the electronic control system 5. The sensor 3-1-4 detects whether the riveted workpiece is in place and feeds back to the electronic control system 5. The electronic control system 5 controls the clamping device 3-1-3 to clamp or release.

[0029] The detection contact of the aging testing mechanism 2 is located on the lower surface of one end of the fixed plate 3-1-1, and the printing needle of the marking mechanism 4 is located on the lower surface of the other end of the fixed plate 3-1-1. The fixed plate 3-1-1 has through holes that pass through the top and bottom surfaces, corresponding to the detection contact and the printing needle. The detection contact and the printing needle can perform aging testing and marking operations on the riveted workpiece through the through holes. Two perpendicular conduits 3-4 are also provided on the lower surface of the workbench 3-1. One conduit 3-4 is arranged horizontally along the edge of the workbench 3-1, and the other conduit 3-4 is arranged vertically. The connecting lines of the aging testing mechanism 2, the riveting mechanism 3, and the marking mechanism 4 are all arranged and connected along the conduit 3-4.

[0030] The upper frame 1-1 has a frame structure. The control cabinet 5-1 and touch screen 5-2 of the electrical control system 5 are located inside the upper frame 1-1. The cabinet door of the control cabinet 5-1 is located on the outer side of the upper frame 1-1 for easy opening and maintenance. The touch screen 5-2 is fixed on the inner side of the upper frame 1-1 for easy operation by the operator at the workstation. The lower frame 1-2 is a box structure with an open side. It contains multiple storage boxes 1-3 of various sizes. The multiple storage boxes 1-3 can be used to store suspicious workpieces and rivet nuts, and are located below the workbench 3-1 for easy access. The workbench 3-1 is above the storage boxes 1-3, and the control drive assembly connected to the workbench 3-1 is on one side. The structure is compact and reasonable. The riveting mechanism 3 also includes rivet guns 3-5 suspended on the upper frame 1-1. The two rivet guns 3-5 are set on the top slide of the upper frame 1-1 by an automatic retractor. The rivet guns 3-5 can slide freely along the slide. The automatic retractor makes it convenient to retract and extend the rivet guns 3-5 and saves the operator's physical strength.

[0031] The marking mechanism 4 in this application uses a scribing marking machine, with its control unit 4-1 housed within the upper frame 1-1 and electrically connected to the printing needle. The scribing marking machine employs specially manufactured titanium alloy needles, completely resolving the printing noise issue and producing a smooth and delicate printing effect, thus improving print quality. The PLC for the electrical control system 5 is a Siemens 1200 series, and the HMI is a Siemens SIMATIC simplified series.

[0032] Workflow Summary: The operator places the car crossbeam and energy-absorbing box on the workbench, presses the start button, and the clamping device presses the riveted parts together. The operator checks the aging test results and, after confirming that the aging is qualified, begins manual riveting. After completing the riveting in the first direction, the operator manually starts the riveting mechanism to flip and perform the riveting in the next direction. After completing the riveting in each direction, the riveting mechanism rotates in the reverse direction to reset, and the riveted parts enter the marking process. After the marking is completed, the clamping device is released, and the operator can remove the riveted parts.
