Description

Technical Field

[0001] This utility model relates to the field of automotive crossbeam processing technology, and in particular to a support device for riveting automotive crossbeams. Background Technology

[0002] In the automobile manufacturing process, the riveting quality of the crossbeams directly affects the overall structural strength and safety of the vehicle. Traditional crossbeam riveting support devices have revealed numerous problems in practical applications, seriously impacting automobile production quality and efficiency.

[0003] Traditional riveting devices often employ vertical clamping. This method has significant limitations. Due to the complex structure and irregular shape of automotive crossbeams, they are prone to shifting under vertical clamping force. This shift leads to misalignment of the holes during riveting. Inaccurate hole alignment not only hinders the riveting process, increasing difficulty and time costs, but also reduces the quality of the riveting. A weak rivet may cause the crossbeam to loosen during vehicle operation, posing a serious safety hazard. Therefore, we propose a support device for automotive crossbeam riveting to address these issues. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a support device for riveting automotive crossbeams.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A support device for riveting automotive crossbeams includes a support platform. A mounting block is fixed to the lower end of the support platform. A visual recognition device is provided at the lower end of the mounting block. Hydraulic telescopic mechanisms are installed on both sides of the mounting block. One end of each hydraulic telescopic mechanism is connected to a driving structure, which is slidably connected to the upper end of the support platform. A movable plate is connected to the lower end of the driving structure. A pneumatic clamping mechanism is installed at the lower end of the movable plate. The pneumatic clamping mechanisms on both sides correspond to each other. A hydraulic clamping mechanism is installed at the upper end of the support platform. Two support platforms are provided at the lower end of the support platform. The hydraulic clamping mechanisms correspond to the support platforms. An anti-collision pad is fixed to one side of the lower end of the movable plate, and two anti-collision pads on the same side correspond to each other.

[0006] Preferably, the hydraulic telescopic mechanism includes two first hydraulic cylinders fixed on both sides of the mounting block.

[0007] Preferably, the driving structure includes a connecting plate fixed to the end of the piston rod of the first hydraulic cylinder, a T-shaped slider fixed to the upper end of the connecting plate, and four T-shaped grooves provided at the lower end of the bearing platform, with one T-shaped slider on the same side engaging with one T-shaped groove on the same side.

[0008] Preferably, the pneumatic clamping mechanism includes a cylinder fixed to one side of the moving plate, and a first clamping plate is fixed to the end of the piston rod of the cylinder, with two first clamping plates on the same side corresponding to each other.

[0009] Preferably, the hydraulic clamping mechanism includes four second hydraulic cylinders fixed to the upper end of the support platform. The piston rods of the second hydraulic cylinders pass through the side wall of the support platform and extend to the lower end of the support platform. The piston rod ends of two second hydraulic cylinders on the same side are jointly fixed to a second clamping plate.

[0010] Preferably, a fixing frame is fixed on both sides of the upper end of the support platform, and a mounting plate is fixed on one side of the upper end of the fixing frame.

[0011] In this utility model, when riveting the crossbeam: 1. Place the crossbeam The operator places the car crossbeam to be riveted on the support platform, which is equipped with clamps to ensure the accuracy of the crossbeam clamping and to prepare for the subsequent riveting work. 2. Scanning and detection The visual recognition device installed at the lower end of the mounting block starts working, performing a comprehensive scan and inspection of the crossbeam placed on the support platform. The visual recognition device can quickly and accurately acquire data such as the shape, size, and current position information of the crossbeam, and transmit this data to the synchronous control system. 3. Adjustment of hydraulic telescopic mechanism The synchronous control system analyzes the position and status of the crossbeam based on the data transmitted from the vision recognition device, and then controls the first hydraulic cylinders installed on both sides of the mounting block to move. The piston rod of the first hydraulic cylinder extends and retracts, driving the connecting plate connected to it to move. Since the upper end of the connecting plate is fixed with a T-shaped slider, and the T-shaped slider is engaged with the T-shaped groove at the lower end of the support platform, the connecting plate will slide along the T-shaped groove, thereby driving the moving plate to move and realizing the position adjustment of the pneumatic clamping mechanism. 4. Pneumatic clamping After the hydraulic telescopic mechanism is adjusted, the synchronous control system issues a command to control the cylinder fixed on one side of the moving plate to move. The piston rod of the cylinder extends and pushes the first clamping plate closer to the crossbeam. The first clamping plates on both sides correspond to each other and clamp the two sides of the crossbeam together to initially fix the crossbeam. 5. Hydraulic clamping The synchronous control system issues another command to control the second hydraulic cylinder fixed on the upper part of the support platform to move. The piston rod of the second hydraulic cylinder passes through the side wall of the support platform and extends downward, pushing the second clamping plate to move downward and clamp and fix the upper end of the crossbeam to ensure that the crossbeam will not move during the riveting process.

[0012] This utility model has the following advantages: 1. The pneumatic clamping mechanisms on both sides and the hydraulic clamping mechanism at the top work together to firmly clamp the crossbeam from multiple directions, effectively preventing the crossbeam from moving during the riveting process and greatly improving the quality and stability of the riveting. 2. The adoption of visual recognition equipment and synchronous control system has enabled automated detection and adjustment, reduced manual intervention, improved the intelligence level of the production process, reduced labor intensity, and increased production efficiency; 3. High-quality riveting ensures that the car crossbeams are firm and reliable during vehicle operation and will not loosen, thereby improving the overall safety of the vehicle. In summary, this utility model firmly clamps the crossbeam from multiple directions, effectively preventing the crossbeam from moving during the riveting process, greatly improving the quality and stability of the riveting. By adopting visual recognition equipment and a synchronous control system, it achieves automated detection and adjustment, reduces manual intervention, improves the intelligence level of the production process, reduces labor intensity, increases production efficiency, and also improves the overall safety of the vehicle.

A visual recognition device 7 is provided at the lower end of the mounting block 2. The visual recognition device 7 uses an advanced high-definition camera and a high-precision image recognition algorithm, which can accurately capture various feature information of the crossbeam in complex industrial environments for scanning and detecting automotive crossbeams. During the scanning process, the visual recognition device 7 will take pictures and analyze the crossbeam from multiple angles to ensure that the information obtained is comprehensive and accurate, and transmit these data to the synchronous control system. After receiving the data, the synchronous control system will further process and analyze the data to provide accurate basis for subsequent operations. Hydraulic telescopic mechanisms are installed on both sides of mounting block 2. One end of the hydraulic telescopic mechanism is connected to a driving structure, which is slidably connected to the upper end of the bearing platform 13. The lower end of the driving structure is connected to a movable plate 5, and a pneumatic clamping mechanism is installed at the lower end of the movable plate 5. The pneumatic clamping mechanisms on both sides correspond to each other. A hydraulic clamping mechanism is installed at the upper end of the bearing platform 13, and two support platforms 4 are provided at the lower end of the bearing platform 13. The hydraulic clamping mechanism and the support platforms 4 correspond to each other. An anti-collision pad 8 is fixed on one side of the lower end of the movable plate 5. The two anti-collision pads 8 on the same side correspond to each other. The anti-collision pads 8 are made of highly elastic rubber material, which has good buffering performance and can effectively avoid damage to the surface of the crossbeam during clamping. The two anti-collision pads 8 on the same side correspond to each other and play a role in protecting the crossbeam. The hydraulic telescopic mechanism includes two first hydraulic cylinders 3 fixed on both sides of the mounting block 2. The driving structure includes a connecting plate 10 fixed to the end of the piston rod of the first hydraulic cylinder 3. A T-shaped slider 1 is fixed at the upper end of the connecting plate 10. Four T-shaped grooves 15 are provided at the lower end of the bearing platform 13. A T-shaped slider 1 on the same side is engaged with a T-shaped groove 15 on the same side. The first hydraulic cylinder 3 has the characteristics of large output force and smooth movement, and can accurately control the movement of the driving structure. The pneumatic clamping mechanism includes a cylinder 6 fixed on one side of the movable plate 5. The piston rod end of the cylinder 6 is fixed with a first clamping plate 9. The two first clamping plates 9 on the same side correspond to each other. The cylinder 6 moves quickly and can quickly clamp the crossbeam. Its clamping force is relatively small and mainly plays the role of initial fixation. The hydraulic clamping mechanism includes four second hydraulic cylinders 12 fixed to the upper end of the support platform 13. The piston rod of the second hydraulic cylinder 12 passes through the side wall of the support platform 13 and extends to the lower end of the support platform 13. The piston rod ends of two second hydraulic cylinders 12 on the same side are jointly fixed with a second clamping plate 14. Fixing frames 11 are fixed on both sides of the upper end of the support platform 13. A mounting plate 16 is fixed on one side of the upper end of the fixing frame 11. The second hydraulic cylinders 12 can provide a large clamping force to ensure that the crossbeam will not move during the riveting process. In this utility model, when riveting the crossbeam: 1. Place the crossbeam The operator places the car crossbeam to be riveted on the support platform 4, which is equipped with clamps to ensure the accuracy of the crossbeam snapping and to prepare for the subsequent riveting work. 2. Scanning and detection The visual recognition device 7 installed at the lower end of the mounting block 2 starts to work, and performs a comprehensive scan and inspection of the crossbeam placed on the support platform. The visual recognition device can quickly and accurately acquire data such as the shape, size and current position information of the crossbeam, and transmit this data to the synchronous control system. 3. Adjustment of hydraulic telescopic mechanism The synchronous control system analyzes the position and state of the crossbeam based on the data transmitted from the visual recognition device, and then controls the first hydraulic cylinder 3 installed on both sides of the mounting block 2 to move. The piston rod of the first hydraulic cylinder 3 extends and retracts, driving the connecting plate 10 connected to it to move. Since the upper end of the connecting plate 10 is fixed with a T-shaped slider 1, and the T-shaped slider 1 is engaged with the T-shaped slide groove 15 at the lower end of the support platform 13, the connecting plate 10 will slide along the T-shaped slide groove 15, thereby driving the moving plate 5 to move and realizing the position adjustment of the pneumatic clamping mechanism. 4. Pneumatic clamping After the hydraulic telescopic mechanism is adjusted, the synchronous control system issues a command to control the cylinder 6 fixed on one side of the moving plate 5 to move. The piston rod of the cylinder 6 extends and pushes the first clamping plate 9 closer to the crossbeam. The first clamping plates 9 on both sides correspond to each other and clamp the two sides of the crossbeam together to initially fix the crossbeam. 5. Hydraulic clamping The synchronous control system issues another command to control the second hydraulic cylinder 12 fixed on the upper end of the support platform 13 to move. The piston rod of the second hydraulic cylinder 12 passes through the side wall of the support platform 13 and extends downward, pushing the second clamping plate 14 to move downward, clamping and fixing the upper end of the crossbeam, ensuring that the crossbeam will not move during the riveting process.
