Technical Field

[0001] This utility model relates to the field of automotive parts testing technology, specifically a tooling for testing automotive anti-collision beams. Background Technology

[0002] In automotive safety protection systems, anti-collision beams are key components for resisting collision impacts. They are rigidly connected to the vehicle's longitudinal beams through low-speed energy-absorbing boxes at both ends. The low-speed energy-absorbing boxes are made of low-yield strength materials and can absorb collision energy through controlled deformation during low-speed vehicle collisions, thereby reducing the degree of damage to the vehicle's longitudinal beams and reducing maintenance costs.

[0003] Before use, car crash beams need to undergo crash testing. During the testing process, the car crash beams need to be clamped and fixed using tooling. However, the existing tooling for testing car crash beams is cumbersome to operate, which can easily affect the testing efficiency. Furthermore, during the impact test, the crash beams are prone to tilting, which greatly reduces the accuracy of the impact test.

[0004] Therefore, it is necessary to provide a tooling for inspecting automotive anti-collision beams to solve the above-mentioned technical problems. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a tooling for detecting automotive anti-collision beams, comprising a base plate, a fixing plate mounted on the top center of the base plate, fixing seats mounted on the front and rear ends of both sides of the fixing plate, an anti-collision beam body fixedly connected to the inner side of the fixing seats, and adjustment mechanisms provided at the bottom of both sides of the fixing plate to adjust the fixing seats to move synchronously apart or in opposite directions, and support components fixed to both sides of the fixing plate at the bottom of the anti-collision beam body.

[0007] Preferably, the long side of the fixing plate is parallel to the long side of the substrate, and the front and rear ends of both sides of the fixing plate are fixedly connected to the four corners of the top of the substrate.

[0008] Preferably, the anti-collision beam body includes an energy-absorbing plate, one side of which is limited and installed inside the fixed seat, and the other side is connected to a connecting seat, and one side of the connecting seat is connected to the anti-collision plate.

[0009] Preferably, the top front and rear ends of the fixed base are equipped with hydraulic rods installed inside the fixed base, and the top of the telescopic end of the hydraulic rod is connected to a pressure plate.

[0010] Preferably, the adjustment mechanism includes a mounting base installed at the bottom center on both sides of the fixed plate, an adjustment rod rotatably connected inside the mounting base, the adjustment rod extending along the length direction of the fixed plate, a connecting block for the adjustment rod to pass through at the bottom center of the fixed base, and mounting brackets fixed to one side of the fixed plate at both ends of the adjustment rod.

[0011] Preferably, the outer wall of the adjusting rod is provided with threads in opposite directions at both ends, and the two ends of the adjusting rod are rotatably connected to the mounting bracket.

[0015] This invention, through its rational structural design and the coordinated operation of its components, provides multiple beneficial effects for the testing of automotive anti-collision beams. Its stable support and fixing structure ensures the accuracy of the testing. The reinforcing plate enhances the connection stability between the fixing plate and the base plate, while the hydraulic rod drives the pressure plate to achieve vertical limiting, combined with the lateral positioning of the energy-absorbing plate, effectively preventing the anti-collision beam from tilting or shifting during impact testing. This results in more accurate and reliable test data, providing precise evidence for evaluating the quality, strength, and other performance characteristics of the anti-collision beam.

[0016] This utility model tooling possesses excellent versatility and adaptability, improving testing efficiency. The adjustment mechanism, driven by a drive device, rotates an adjusting rod with a reverse thread, allowing for flexible adjustment of the fixing seat spacing to meet the fixing requirements of anti-collision beams of different sizes. The springs in the support components can expand and contract according to the size of the anti-collision beam and the stress conditions, further enhancing the tooling's adaptability. It eliminates the need for separate testing tooling for anti-collision beams of different sizes, reducing equipment investment and shortening tooling changeover time, thus improving the continuity and efficiency of testing.

The embodiments of this utility model will be described below based on its overall structure.

[0024] Please see Figure 1-4A tooling for detecting automotive anti-collision beams includes a base plate 1, a fixing plate 2 mounted on the top center of the base plate 1, fixing seats 3 mounted on the front and rear ends of both sides of the fixing plate 2, an anti-collision beam body 4 fixedly connected to the inner side of the fixing seats 3, and adjustment mechanisms 5 provided on the bottom sides of the fixing plate 2 to adjust the fixing seats 3 to move synchronously apart or in opposite directions. Support components 6 fixed to both sides of the fixing plate 2 are provided at the bottom of the anti-collision beam body 4.

[0025] like Figure 1-4 As shown, the long side of the fixing plate 2 is parallel to the long side of the substrate 1. The front and rear ends of both sides of the fixing plate 2 are fixedly connected with the reinforcing plates 10 fixed at the four corners of the top of the substrate 1. The stability between the fixing plate 2 and the substrate 1 is improved by setting the reinforcing plates 10.

[0026] like Figure 1-4 As shown, the anti-collision beam body 4 includes an energy-absorbing plate 401. One side of the energy-absorbing plate 401 is limited and installed inside the fixed seat 3, and the other side is connected to a connecting seat 402. One side of the connecting seat 402 is connected to an anti-collision plate 403. The energy-absorbing plate 401 is limited and installed inside the fixed seat 3 to fix the anti-collision plate 403. During the test, the impact force of a simulated low-speed vehicle collision is provided to the anti-collision plate 403, and the collision energy is absorbed by the energy-absorbing plate 401. After the test, the mass strength and other capabilities of the anti-collision beam body 4 are tested.

[0027] like Figure 1-4 As shown, hydraulic rods 7 are installed at both the front and rear ends of the top of the fixed base 3. A pressure plate 8 is connected to the top of the telescopic end of the hydraulic rod 7. The energy-absorbing plate 401 is limited and installed inside the mounting groove opened on the top of the fixed base 3. At this time, the pressure plate 8 is pressed against the top of the energy-absorbing plate 401 by the retraction of the hydraulic rod 7, thereby limiting it in the vertical direction and preventing the anti-collision beam body 4 from tilting during the impact test, thereby reducing the accuracy of the impact detection.

[0028] like Figure 1-4 As shown, the adjustment mechanism 5 includes a mounting base 501 installed at the bottom center of both sides of the fixed plate 2. An adjustment rod 502 is rotatably connected inside the mounting base 501. The adjustment rod 502 extends along the length of the fixed plate 2. A connecting block 503 for the adjustment rod 502 to pass through is connected to the bottom center of the fixed base 3. The two ends of the adjustment rod 502 are connected to mounting brackets 504 fixed to one side of the fixed plate 2. By adjusting the connecting blocks 503 at both ends to move synchronously towards or away from each other on the outer wall of the adjustment rod 502, the distance between the fixed bases 3 can be adjusted, thereby stably fixing the anti-collision beam body 4 of different sizes.

[0029] like Figure 1-4As shown, the two ends of the outer wall of the adjusting rod 502 are provided with threads in opposite directions, and the two ends of the adjusting rod 502 are rotatably connected to the mounting bracket 504. One end of the mounting bracket 504 on one side is connected to a drive device 9 that can drive the adjusting rod 502 to rotate. The drive device 9 is a servo motor. The drive device 9 can drive the adjusting rod 502 to rotate in both directions, thereby driving the connecting block 503 to move towards or away from each other in the threaded area provided on the outer wall of the adjusting rod 502.

[0030] like Figure 1-4 As shown, the support assembly 6 includes a support plate 601 fixed to the bottom of both sides of the fixed plate 2. Springs 602 are equidistantly installed on the top of the support plate 601. A support plate 603 is connected to the top of the springs 602. The support plate 601 supports the anti-collision beam body 4, preventing tilting when it hits the anti-collision plate 403. The springs 602 allow the support plate 601 to move up and down to adapt to anti-collision beam bodies 4 of different sizes.

[0031] Working principle: The base plate 1 serves as the basic load-bearing component of the entire tooling, providing a stable mounting platform for all the structures above. The fixing plate 2 is installed at the top center of the base plate 1, with its long side parallel to the long side of the base plate 1, ensuring the rationality of the structural layout. The reinforcing plates 10 connected to the front and rear ends of the fixed plate 2 are fixed to the top four corners of the base plate 1. With the stability of the triangular structure, the force on the fixed plate 2 is distributed and transferred to the base plate 1, which significantly improves the overall rigidity and deformation resistance of the connection between the fixed plate 2 and the base plate 1, and provides a stable structural foundation for subsequent testing operations. The energy-absorbing plate 401 of the anti-collision beam body 4 is limited and installed in the mounting groove inside the fixed seat 3, realizing the initial lateral positioning. When the hydraulic rods 7 at the front and rear ends of the top of the fixed seat 3 are working, their telescopic ends retract and drive the pressure plate 8 to move downward, so that the pressure plate 8 is tightly pressed against the top of the energy-absorbing plate 401, thereby effectively limiting the anti-collision beam body 4 in the vertical direction. This double fixing method can prevent the anti-collision beam body 4 from tilting or displacing during the impact test, ensuring the accuracy of the impact test. The adjustment mechanism 5 is the key to realizing the versatility of the tooling. Mounting base 501 provides rotational support for adjusting rod 502, which extends along the length of fixed plate 2. Its outer walls have oppositely oriented threads at both ends, which are threadedly connected to connecting blocks 503 at the bottom of fixed base 3. When driving device 9 drives adjusting rod 502 to rotate forward or backward, the connecting blocks 503 at both ends, under the action of the reverse threads, will drive fixed base 3 to move synchronously towards or away from each other, thereby adjusting the distance between fixed bases 3 to accommodate the fixing requirements of anti-collision beam bodies 4 of different sizes. Support assembly 6 provides auxiliary support for anti-collision beam bodies 4. Support plate 601 is fixed to the bottom of both sides of fixed plate 2, providing the mounting base for the entire support structure. The springs 602, which are equidistantly installed on the top of the support plate 601, have elastic telescopic characteristics. The support plate 603 connected to the top of the support plate 601 contacts the bottom of the anti-collision beam body 4. When the anti-collision plate 403 is impacted, the support plate 603 can effectively prevent the anti-collision beam body 4 from tilting. At the same time, the springs 602 can extend and retract according to the size and stress of the anti-collision beam body 4, which not only adapts to the support requirements of anti-collision beams of different sizes, but also plays a certain buffering role in the inspection process, reducing the adverse effects of impact force on the tooling and the anti-collision beam body.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
