[0002] The front bumper beam assembly, as one of the important protective structures of a car, typically includes components such as the bumper beam body, energy-absorbing boxes, and mounting plates. During the manufacturing of the front bumper beam assembly, the various components need to be welded together. Positioning devices are often used during welding to prevent displacement of the components due to stress, especially in the welding of the energy-absorbing boxes and the bumper beam body. The bumper beam body, as the core structure directly bearing the impact, is usually made of high-strength materials (such as aluminum alloy or high-strength steel) to resist low-speed collisions and transfer high-speed collision energy. The energy-absorbing boxes, located at both ends of the bumper beam, absorb low-speed collision energy through crushing deformation, reducing the impact on the longitudinal beams of the vehicle body. The connection quality between the energy-absorbing boxes and the bumper beam body has a significant impact on the quality of the front bumper beam assembly. However, the welding process of the front bumper beam assembly suffers from problems such as inconvenient clamping and insufficient adjustment flexibility. Utility Model Content

[0016] Please see Figure 1-4 This utility model provides a technical solution: a welding positioning device for a front bumper beam assembly of an automobile, including a base plate 1. Two sets of positioning frames 2 are symmetrically arranged on the upper side of the base plate 1. The two sets of positioning frames 2 are used for supporting and positioning both ends of the bumper beam body, improving the support stability of the front bumper beam during welding. The positioning frames 2 are slidably installed on the upper side of the base plate 1. By adjusting the distance between the two sets of positioning frames 2, positioning is used for welding different models of front bumper beam assemblies, thus improving the applicability. An adjustment component for adjusting the position of the positioning frames 2 is provided on the side of the base plate 1. A support plate 7 is fixed on the side of the positioning frame 2. The support plate 7 is used for supporting and limiting the bumper beam body in the front bumper beam assembly, making it easy to mount the bumper beam body on the positioning frame 2 for welding. A push plate 9 is slidably arranged on the support plate 7. A positioning component for positioning the push plate 9 is provided on the side of the positioning frame 2. The push plate 9 is used for positioning the bumper beam body. A pressure plate 14 is slidably arranged on the side of the positioning frame 2. A lifting component for adjusting the position of the pressure plate 14 is provided on the side of the positioning frame 2. The pressure plate 14 is used for pressing and positioning the energy-absorbing box.

[0017] The adjustment assembly includes an adjustment rod 3 rotatably mounted on the upper side of the base plate 1, with threads of opposite directions at both ends of the adjustment rod 3. A first threaded cylinder 5, which is threadedly connected to the adjustment rod 3, is mounted on the positioning frame 2. During use, the distance between the two sets of positioning frames 2 is adjusted according to the model of the front anti-collision beam assembly or the installation position of the energy absorption box. By rotating the adjustment rod 3, the positioning frames 2 move synchronously under the action of the first threaded cylinder 5, moving closer or further apart from each other, thereby improving the applicability of this positioning device.

[0018] A motor unit 4 is installed on the upper side of the base plate 1. The output shaft of the motor unit 4 is connected and fixed to one end of the adjusting rod 3 to control the operation of the motor unit 4. The motor unit 4 drives the adjusting rod 3 to rotate, which is used to adjust the position of the two sets of positioning frames 2, so as to facilitate the use of this positioning device. Preferably, the positioning frame 2 has an L-shaped structure, and a triangular plate 6 is fixed on the side of the positioning frame 2. The triangular plate 6 is located at the corner of the positioning frame 2 to improve the structural strength of the positioning frame 2. The first threaded cylinder 5 is fixed on the triangular plate 6.

[0019] A movable frame 8 is slidably mounted on the support plate 7, and a push plate 9 is fixed on the movable frame 8. The movable frame 8 is used to improve the stability of the push plate 9 when it moves and the positioning strength during use. The positioning component includes a screw 11, one end of which is rotatably connected to the positioning frame 2, and the other end of which is equipped with a handle 12. A second threaded cylinder 10 that is threadedly connected to the screw 11 is installed on the side of the movable frame 8. After the anti-collision beam body is mounted on the support plate 7, the screw 11 is rotated by the handle 12 to drive the second threaded cylinder 10 to move the movable frame 8, so that the push plate 9 on the side of the movable frame 8 contacts the side of the anti-collision beam body, and the push plate 9 presses the anti-collision beam body to position it on the positioning frame 2, so as to avoid the welding position displacement caused by the movement of the anti-collision beam body during the welding process.

[0020] A positioning frame 13 is slidably sleeved on the positioning frame 2. A pressure plate 14 is fixed on the side of the positioning frame 13 near the push plate 9. The positioning frame 13 is used to improve the stability of the pressure plate 14 when it moves and the positioning strength during use. The lifting assembly includes an electric telescopic cylinder 15. The electric telescopic cylinder 15 is installed on the positioning frame 2, and the telescopic end of the electric telescopic cylinder 15 is connected and fixed to the side of the positioning frame 13. The operation of the electric telescopic cylinder 15 is controlled so that the positioning frame 13 can be moved on the positioning frame 2, which facilitates the adjustment of the height of the pressure plate 14. The pressure plate 14 contacts the side of the energy-absorbing box to position the energy-absorbing box on the anti-collision beam body, preventing the energy-absorbing box from moving under force during the welding process and causing the welding position to shift. The pressure plate 14 presses down on the energy-absorbing box to make effective contact with the side of the anti-collision beam body, which facilitates the welding of the energy-absorbing box to the side of the anti-collision beam body and ensures the welding quality.

This method is a common technical means used by technicians and will not be described in detail here.

[0022] This automotive front bumper beam assembly welding positioning device is suitable for welding and preparing different models of front bumper beam assemblies, especially for connecting the bumper beam body and the energy-absorbing box. During the welding process, by squeezing the bumper beam body and the energy-absorbing box, it can not only play a good positioning role, but also ensure that the two are effectively pressed together, thereby improving the welding quality.
