Description
Technical Field

[0002] The front bumper beam assembly is an important energy-absorbing device in the car bumper system. It is installed in front of the crossbeam and the longitudinal beam of the frame and connected to the energy-absorbing box. It exists as a low-speed safety protection system. Its main function is to absorb and disperse the impact force when the vehicle is involved in a frontal collision, and protect the occupants from serious injury.
[0003] The front bumper beam, typically installed on the front of the vehicle, prevents the vehicle from flying forward or twisting during a collision, thus protecting the vehicle and its passengers. The welding precision of the front bumper beam directly affects the connection and fit of the energy-absorbing box. Low welding precision results in extremely low strength at the weld between the formed bumper beam and the energy-absorbing box, easily leading to positional deviations and posing a significant safety hazard. Therefore, high precision requirements are placed on the overall forming tolerance of the welded front bumper beam. Furthermore, automotive energy-absorbing boxes come in various shapes, requiring different welding fixtures to ensure welding precision with the bumper beam. Currently, welding positioning of automotive energy-absorbing boxes during the prototyping stage is mostly manual, which involves cumbersome operations and risks such as welding misalignment.

[0028] To achieve the above objectives, this utility model proposes a welding fixture for anti-collision beams, used for welding anti-collision beams and energy-absorbing boxes.

[0030] like Figure 1-6 As shown, the anti-collision beam welding fixture includes: a base plate 1 and a base 2 mounted on the base plate 1. In this invention, the base plate 1 serves as the welding reference, ensuring the accuracy of the installation and relative positions of each part during the entire welding process. The base 2 is positioned above the base plate 1. In this invention, the base plate 1 and the base 2 are detachably connected. The position of the base 2 on the base plate 1 can be changed according to the shape of the energy-absorbing box to be welded. Preferably, the base 2 is connected to the base plate 1 by bolts. In practical applications, the base plate 1 of the energy-absorbing box is placed on the base 2 and positioned by a positioning pin connected to the base 2. In this invention, preferably, two positioning pins are used to position the base plate 1 of the energy-absorbing box on the base 2. Of course, the position of the base 2 on the base plate 1 can be changed as the size of the energy-absorbing box changes.
[0031] The first support mechanism 3 is disposed on one side of the base 2, and the second support mechanism 4 is disposed on the other side of the base 2; the first support mechanism 3 is provided with a first opening mechanism 5; the second support mechanism 4 is provided with a second opening mechanism 6; for example Figure 1 As shown, the first opening mechanism 5 and the second opening mechanism 6 are on the same horizontal plane in the horizontal direction, and the horizontal planes in the vertical direction of the first opening mechanism 5 and the second opening mechanism 6 are perpendicular to each other; the positioning plate 7 is set on the base 2, and the positioning plate 7 is connected to one end of the connecting rod 8, and the other end of the connecting rod 8 is provided with the third opening mechanism 9; the horizontal plane in the vertical direction of the third opening mechanism 9 after installation through the positioning plate 7 and the connecting rod 8 is perpendicular to the horizontal plane in the horizontal direction of the first opening mechanism 5 and the second opening mechanism 6; the support rod 10 is set on the base 2, and the support rod 10, the first opening mechanism 5, the second opening mechanism 6 and the third opening mechanism 9 form an installation space; during the use stage, the vertical plates of the energy absorption box are restricted to the installation space for welding operations.
[0032] During the usage phase, the positions of the first opening mechanism 5, the second opening mechanism 6, and the third opening mechanism 9 are changed. The first and second upright plates of the energy-absorbing box are placed at the positions of the support rod 10, which supports the first and second upright plates. Specifically, the first and second upright plates supported by the support rod 10 are perpendicular to each other. Then, the third and fourth upright plates are placed in positions relative to the first and second upright plates limited by the support rod 10. The positions of the first opening mechanism 5, the second opening mechanism 6, and the third opening mechanism 9 are adjusted so that the first opening mechanism 5 and the second opening mechanism 6 contact the third and fourth upright plates, respectively, to limit their positions. This, in conjunction with the support rod 10, helps to prevent errors in the shape of each upright plate during the welding stage. The third opening mechanism 9 presses the opening direction of the energy-absorbing box to prevent large positional deviations in the vertical direction. After installation, the positions of the first opening mechanism 5, the second opening mechanism 6, and the third opening mechanism 9 can be changed to facilitate the removal of the welded energy-absorbing box.

In this utility model, the first support group 41 and the second support group 42 have the same structure, and the second support group 42 is disposed on the first support group 41, and the support block 43 is installed through the second support group 42. After connection, a bracket structure is formed, so that the support block 43 is placed on a horizontal plane in the horizontal direction, and the second opening mechanism 6 is disposed on the support block 43, so that there is a distance between the second opening mechanism 6 and the base plate 1 after installation. When the fourth upright plate is set, the second opening mechanism 6 can contact the middle of the fourth upright plate to ensure that the fourth upright plate is subjected to uniform force.
[0034] like Figure 2 and 4As shown, the first support group 41 includes a top block 411 and a pressure block 412. One end of the top block 411 is connected to the pressure block 412, and the top block 411 is mounted on the base 2. Specifically, the top block 411 and the pressure block 412 are vertically connected. After the top block 411 is mounted on the base 2, the pressure block 412 is perpendicular to the base 2. Of course, to increase the connection strength between the top block 411 and the pressure block 412, in this invention, a reinforcing block 413 is preferably provided between the top block 411 and the pressure block 412. The reinforcing block 413 increases the fixing strength between the top block 411 and the pressure block 412. It should be noted that the second support group 42 has the same structure as the first support group 41, except that the top block on the second support group 42 is connected to the pressure block 412 on the first support group 41, so that the pressure block on the second support group 42 is in a horizontal state and then connected to the support block 43, so as to ensure that the second opening mechanism 6 can be in the appropriate position.
[0035] It should be further explained that in this utility model, the first support mechanism 3 and the second support mechanism 4 have the same structure, only the position and the plane in the vertical direction are different. To save space, the specific structure of the first support mechanism 3 will not be described in detail in this utility model.
[0036] like Figure 3 As shown, the first opening mechanism 5 includes a first actuating device 51 and a first pressure arm 52. The first actuating device 51 is mounted on the first support mechanism 3; the first pressure arm 52 is mounted on the first actuating device 51. Specifically, the first pressure arm 52 is detachably mounted on the first actuating device 51, so that the model of the first pressure arm 52 can be changed according to the size change of the energy absorption box; wherein, the first pressure arm 52 is an L-shaped pressure arm.
[0037] like Figure 1-3 As shown, the third opening mechanism 9 includes a second actuating device 91 and a second pressure arm 92. The second actuating device 91 is mounted on the connecting rod 8; the second pressure arm 92 is mounted on the second actuating device 91. Specifically, the second pressure arm 92 is detachably mounted on the second actuating device 91, allowing for replacement of the second pressure arm 92 model according to changes in the size of the energy-absorbing box. The second pressure arm 92 is an F-shaped pressure arm. Additionally, as... Figure 1-3 As shown in Figure 6, the second actuating device 91 is mounted on the connecting rod 8. Preferably, the second actuating device 91 is fixed to the connecting rod 8 by bolts. During use, the position of the second actuating device 91 on the connecting rod 8 can be adjusted, thereby adjusting the position of the second actuating device 91 in the vertical and horizontal directions, making the position control of the third opening mechanism 9 more flexible.

The first support arm 101 is mounted on the base 2, and the second support arm 102 is connected to the first support arm 101. In this invention, preferably, both the first support arm 101 and the second support arm 102 are L-shaped support arms. The short side of the first support arm 101 is mounted on the base 2, and the short side of the second support arm 102 is connected to the long side of the first support arm 101, providing support through one end of the long side of the second support arm 102. Of course, in this invention, to increase the support effect, it is preferable to use two support rods 10 to support one upright plate. Two support rods 10 can be defined as a fixed support group. Figure 5 As shown, in this utility model, two fixed support groups are required to support the first or second upright plate.
[0039] In summary, the anti-collision beam welding fixture provided by this utility model fixes the base plate 1 of the energy-absorbing box to the base plate 2 by setting a base 2 on the base plate 1. The side plate and opening position of the energy-absorbing box are limited by the cooperation of the support rod 10, the first opening mechanism 5 on the first support mechanism 3, the second opening mechanism 6 on the second support mechanism 4, the positioning plate 7 and the third opening mechanism 9 on the connecting rod 8, and the support rod 10.

In the subsequent welding process, the welding accuracy can be ensured and the welding precision can be improved. Compared with the prior art, the technical solution of this utility model has a simple structure, good clamping effect, strong applicability, simple operation and low cost. It can ensure that the position of the energy-absorbing box will not shift during welding and improve the welding precision of the product.
