[0002] In the automobile manufacturing process, the assembly quality of the front bumper beam and energy-absorbing box has a crucial impact on the safety performance of the vehicle.
[0003] Traditional assembly methods for front bumper beam energy-absorbing boxes largely rely on manual operation, which is not only inefficient but also makes it difficult to guarantee assembly accuracy. Problems such as missing bolts or inconsistent tightening torque can easily occur, leading to unstable assembly quality. Furthermore, the positioning and fixing of components during manual assembly are not precise enough, further affecting the assembly effect and product quality. Therefore, we propose a front bumper beam energy-absorbing box assembly workstation to solve these problems. Summary of the Invention
[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a front bumper beam energy-absorbing box assembly workstation.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A front bumper beam energy-absorbing box assembly workstation includes a movable base, an upper frame mounted on the top of the movable base, and a worktable mounted on the top of the movable base. A front bumper beam, a left energy-absorbing box, and a right energy-absorbing box are placed on the worktable.
[0007] The top of the workbench is provided with two positioning mechanisms 1 for positioning the two ends of the anti-collision beam, and two positioning mechanisms 2 for positioning the middle position of the anti-collision beam. Both positioning mechanisms 2 are located between the two positioning mechanisms 1. The top of the workbench is provided with two box positioning seats for the left energy-absorbing box and the right energy-absorbing box.
[0008] A tightening gun suspension balancer is installed on the top inner wall of the upper frame, and the tightening gun suspension balancer is connected to a tightening gun for tightening bolts via a connecting assembly.
[0009] Preferably, a PLC control box is fixedly installed on one side of the movable base, and a human-machine interface is installed on one side of the upper frame. Both the human-machine interface and the tightening gun are electrically connected to the PLC control box.
[0010] Preferably, the top of the workbench is provided with a clamping assembly, which is used for clamping and fixing the left and right energy-absorbing boxes.
[0011] Preferably, the positioning mechanism includes a fixed base and a front anti-collision beam end positioning base.

[0012] Preferably, a rotating frame is fixedly installed on the positioning seat at the end of the front bumper beam, a rotating shaft is rotatably installed inside the rotating frame, a drive rod is fixedly installed on the rotating shaft, a clamping plate for pressing the front bumper beam is fixedly installed at one end of the drive rod, a hydraulic cylinder is installed on the positioning seat at the end of the front bumper beam, a U-shaped seat is installed on the output shaft of the hydraulic cylinder, and the other end of the drive rod is rotatably installed inside the U-shaped seat.
[0013] Preferably, the second positioning mechanism includes a fixed plate and a positioning plate. The fixed plate is fixedly installed on the workbench, and a positioning plate for positioning the front anti-collision beam is fixedly installed on the fixed plate.

[0016] The beneficial effects of this utility model are:
[0017] 1. By setting up positioning mechanism one, positioning mechanism two, and a box positioning seat, the left energy-absorbing box, right energy-absorbing box, and front bumper beam can be precisely positioned, ensuring the accurate positioning of each component during assembly and improving assembly precision. Simultaneously, the clamping assembly effectively secures the energy-absorbing box, preventing displacement during assembly.

[0027] The present application will be further described in detail below with reference to Figures 1-6.
[0028] This application discloses a front anti-collision beam energy-absorbing box assembly workstation.
[0029] Referring to Figures 1-6, the front bumper beam energy-absorbing box assembly workstation includes a movable base 101. An upper frame 102 is mounted on the top of the movable base 101. A workbench 103 is mounted on the top of the movable base 101. The front bumper beam 301, the left energy-absorbing box 304, and the right energy-absorbing box 305 are placed on the workbench 103. Two positioning mechanisms 1 for positioning the ends of the bumper beam are provided on the top of the workbench 103. Two positioning mechanisms 2 for positioning the middle position of the bumper beam are provided on the top of the workbench 103, and both positioning mechanisms 2 are located between the two positioning mechanisms 1. Two box positioning seats for the left energy-absorbing box 304 and the right energy-absorbing box 305 are provided on the top of the workbench 103. A tightening gun suspension balancer 201 is installed on the top inner wall of the upper frame 102. The tightening gun suspension balancer 201 is connected to a tightening gun 202 for tightening bolts through a connecting assembly.
[0030] In this embodiment, a PLC control box 203 is fixedly installed on one side of the movable base 101, and a human-machine interface 204 is installed on one side of the upper frame 102. Both the human-machine interface 204 and the tightening gun 202 are electrically connected to the PLC control box 203. The PLC control box 203 enables centralized control and data interaction between the human-machine interface 204 and the tightening gun 202. Operators can conveniently set tightening parameters and monitor assembly data in real time through the human-machine interface 204, which greatly improves the intelligence and automation of the assembly process and effectively reduces errors caused by manual intervention.
[0031] In this embodiment, a clamping assembly 303 is provided on the top of the workbench 103, and the clamping assembly 303 is used to clamp and fix the left energy-absorbing box 304 and the right energy-absorbing box 305. The clamping assembly 303 can firmly fix the energy-absorbing box on the box positioning seat before assembly, and prevent the energy-absorbing box from shifting due to external force during subsequent tightening operations, so as to ensure the accurate relative position of the energy-absorbing box and the front anti-collision beam 301, laying the foundation for high-quality assembly.
[0032] In this embodiment, the positioning mechanism includes a fixed base 401 and a front bumper beam end positioning seat 402. The fixed base 401 is fixedly installed on the top of the workbench 103, and the front bumper beam end positioning seat 402 for positioning the end of the front bumper beam 301 is installed on the top of the fixed base 401. This structural design achieves precise positioning of the end of the front bumper beam 301, ensuring that the installation reference of the front bumper beam 301 on the workbench 103 is accurate, effectively preventing the overall assembly effect from being affected by the end position deviation, and improving assembly consistency.
[0033] In this embodiment, a rotating frame 403 is fixedly installed on the front bumper beam end positioning seat 402. A rotating shaft 404 is rotatably installed inside the rotating frame 403. A drive rod 405 is fixedly installed on the rotating shaft 404. A clamping plate 406 for pressing the front bumper beam 301 is fixedly installed at one end of the drive rod 405. A hydraulic cylinder 407 is installed on the front bumper beam end positioning seat 402. A U-shaped seat 408 is installed on the output shaft of the hydraulic cylinder 407. The other end of the drive rod 405 is rotatably installed inside the U-shaped seat 408. The hydraulic cylinder 407 drives the clamping plate 406 to rotate and press the end of the front bumper beam 301. Compared with the manual pressing method, the operation is simpler and less labor-intensive, and the clamping force is stable and controllable. It can quickly and reliably fix the front bumper beam 301 and improve assembly efficiency.
[0034] In this embodiment, the second positioning mechanism includes a fixed plate 501 and a positioning plate 502. The fixed plate 501 is fixedly installed on the workbench 103, and the positioning plate 502 for positioning the front bumper beam 301 is fixedly installed on the fixed plate 501. The second positioning mechanism cooperates with the first positioning mechanism to simultaneously position the bumper beam from both ends and the middle, forming a multi-point positioning system. This comprehensively restricts the degree of freedom of movement of the front bumper beam 301 on the workbench 103, further improving the positioning accuracy and stability of the front bumper beam 301.
[0035] In this embodiment, a hydraulic cylinder 506 is mounted on the fixed plate 501, and a rotating shaft 503 is rotatably mounted on the positioning plate 502. Rotating plates 504 are fixedly mounted on both ends of the rotating shaft 503, and a single clamping plate 505 is fixedly mounted between the two rotating plates 504. A U-shaped seat 507 is mounted on the output shaft of the hydraulic cylinder 506, and one end of the clamping plate 505 is rotatably mounted within the U-shaped seat 507. The hydraulic cylinder 506 drives the clamping plate 505 to rotate and clamp the middle of the front bumper beam 301. This, combined with the clamping action of the clamping plate 406 on the ends of the bumper beam, ensures that the front bumper beam 301 is subjected to uniform force during assembly, preventing deformation due to uneven local force and guaranteeing the assembly quality of the front bumper beam 301.
[0036] In this embodiment, pins are rotatably mounted on the inner walls of both sides of U-shaped seat 2 507 and U-shaped seat 1 408. Pressure plate 2 505 is fixedly fitted onto the pins inside U-shaped seat 2 507, and pressure plate 1 406 is fixedly fitted onto the pins inside U-shaped seat 1 408. The pin configuration provides stable support and a rotating shaft 404 for the rotation of the pressure plates, reducing friction and wear during rotation, ensuring the flexibility and reliability of the pressure plate rotation, extending the service life of the pressure mechanism, and reducing equipment maintenance costs.
[0037] In this invention, the left energy-absorbing box 304 and the right energy-absorbing box 305 are placed on their corresponding energy-absorbing box positioning seats 302. The boxes are fixed by the clamping assembly 303. The front anti-collision beam 301 is placed on the front anti-collision beam end positioning seat 402 and the positioning plate 502, thus achieving the positioning of the left energy-absorbing box 304, the right energy-absorbing box 305, and the front anti-collision beam 301. By activating hydraulic cylinder 407, the hydraulic cylinder 407 drives the drive rod 405 to rotate around the rotating shaft 404 via the U-shaped seat 408. The rotation of the drive rod 405 causes the clamping plate 406 to rotate towards the anti-collision beam and clamp it in place. Activating hydraulic cylinder 506... 06 is moved via the output shaft to the U-shaped seat 507. The U-shaped seat can rotate the clamping plate 505 around the rotating shaft 503, so that the clamping plate 505 can clamp and fix the front anti-collision beam 301. The tightening gun 202 can tighten the connecting bolts on the anti-collision beam, the left energy-absorbing box 304 and the right energy-absorbing box 305. Through the tightening counting and torque monitoring and setting system and the PLC main control system, the number of assembly bolts in the assembly process is prevented from being missed and the tightening torque is stable and consistent. If there is a missing assembly part or bolt or the tightening force does not reach the set value, the system will display the corresponding alarm prompt on the human-machine interface 204, and the workpiece cannot be removed without being clamped.
[0038] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
