Description

Technical Field

[0001] This utility model relates to the technical field of instrument panel crossbeam strength testing equipment, specifically an instrument panel crossbeam strength testing device. Background Technology

[0002] The dashboard crossbeam, also known in the industry as the "dashboard frame," is a structural component that provides installation and support for the dashboard assembly and other system parts. It is an important supporting structure for the interior components of the car's cockpit, directly connected to the vehicle body. It bears, absorbs, and transmits energy and loads during a vehicle collision, and is a crucial structure related to occupant protection performance. Dashboard crossbeams produced in the factory require strength testing equipment, such as tensile testing devices and compressive testing devices, to measure parameters such as maximum load and degree of deformation, ensuring that the manufactured dashboard crossbeams are qualified and improving vehicle safety.

[0003] Most instrument panel crossbeam pressure strength testing devices currently use a fixing fixture to fix the instrument panel crossbeam to the worktable, and then activate the hydraulic cylinder to perform a pressure test on the instrument panel crossbeam. However, vehicles produced in the factory have various specifications, resulting in different sizes of instrument panel crossbeams. The existing fixing fixtures are relatively simple and cannot fix instrument panel crossbeams of different sizes, thus limiting the testing equipment. Utility Model Content

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] This utility model provides a technical solution: such as Figure 1 - Figure 4 As shown, in this embodiment, a dashboard crossbeam strength testing device includes a base 1. A fixed platform 2 is fixedly connected to the upper center of the base 1. An electric cylinder 11 is fixedly installed on one side of the fixed platform 2. A push rack 3 is fixedly connected to the output end of the electric cylinder 11. A gear 10 meshes with one side of the push rack 3. A bidirectional screw 4 is fixedly connected to the inner wall of the gear 10. The two ends of the bidirectional screw 4 are rotatably connected to the middle of the inner wall of the fixed platform 2. Moving plates 5 are threadedly connected to both sides of the outer surface of the bidirectional screw 4. A connecting frame 6 is fixedly connected to one side of each of the two moving plates 5. A connecting plate 9 is fixedly connected to one side of each of the two connecting frames 6. One side of the instrument panel is threaded with a fixed threaded rod 7. One end of each fixed threaded rod 7 is rotatably connected to a clamping plate 8. By activating the electric cylinder 11, the push rack 3 slides in the guide rail 21, pushing the rack 3 to drive the bidirectional screw 4 to rotate, causing the two moving plates 5 to move closer and further apart, adjusting the length of the instrument panel crossbeam on the connecting frame 6. After adjustment, the two ends of the instrument panel crossbeam are placed on the two connecting frames 6 respectively, and then the two fixed threaded rods 7 are rotated so that the two clamping plates 8 clamp the two ends of the instrument panel crossbeam, thus fixing instrument panel crossbeams of different sizes. This structure is simple, easy to operate, and improves the versatility of the equipment.

[0021] like Figure 2 As shown, a slide groove 19 is provided on one side of the upper end of the fixed platform 2. A support frame 20 is slidably connected to the inner wall of the slide groove 19. Through the structural design of the slide groove 19 and the support frame 20, the protruding position of the instrument panel beam is supported.

[0022] like Figure 2 and Figure 3 As shown, a guide rail 21 is slidably connected to the outer surface of the push rack 3. The lower end of the guide rail 21 is fixedly connected to the inner bottom of the fixed platform 2. The guide rail 21 guides the push rack 3 through its structural design.

[0023] like Figure 1 As shown, a protective cover 18 is fixedly connected to the upper end of the base 1. A protective door 12 is rotatably connected to one side of the protective cover 18. A handle 14 is fixedly connected to one side of the protective door 12. A transparent glass 13 is fixedly installed on the inner wall of the protective door 12. Through the structural design of the protective cover 18 and the protective door 12, it is possible to prevent the hydraulic cylinder 16 from being too high and crushing the instrument panel beam. Some of its fragments will jump out and accidentally injure the staff. When the equipment is under pressure testing, the situation inside the protective cover 18 can be observed through the transparent glass 13.

[0024] like Figure 1 and Figure 4 As shown, a hydraulic cylinder 16 is installed inside the protective cover 18. The output end of the hydraulic cylinder 16 is fixedly connected to a strength detection plate 17. Through the structural design of the hydraulic cylinder 16 and the strength detection plate 17, the pressure strength of the instrument panel beam can be tested.

[0025] like Figure 4 As shown, a movable slide 15 is fixedly connected to one side of the inner wall of the protective cover 18. A drive device 24 is fixedly installed on one side of the movable slide 15. The output end of the drive device 24 is connected to a drive threaded rod 22. A movable frame 23 is threadedly connected to the outer surface of the drive threaded rod 22. One side of the movable frame 23 is fixedly connected to one side of the hydraulic cylinder 16. By turning on the drive device 24, the drive threaded rod 22 rotates inside the movable slide 15, causing the hydraulic cylinder 16 to slide along the movable slide 15. This adjusts the position of the strength detection plate 17 on the instrument panel crossbeam, enabling pressure strength detection at different positions on the instrument panel crossbeam and improving the detection efficiency of the equipment.

[0026] This utility model provides a device for testing the strength of a dashboard crossbeam, the specific working principle of which is as follows:

[0027] When performing pressure strength testing on the instrument panel crossbeam, first place both ends of the instrument panel crossbeam on the two connecting brackets 6 respectively, then rotate the two fixed threaded rods 7 to clamp the two ends of the instrument panel crossbeam with the two clamping plates 8. Then, activate the hydraulic cylinder 16, and the strength testing pressure plate 17 applies pressure to the instrument panel crossbeam. Observe the deformation of the instrument panel crossbeam under different pressures. When performing pressure testing on different positions of the instrument panel crossbeam, activate the drive device 24 to drive the threaded rod 22 to rotate in the movable slide 15, so that the hydraulic cylinder 16 slides along the movable slide 15. Adjust the position of the strength testing pressure plate 17 on the instrument panel crossbeam, and then activate the hydraulic cylinder 16 to perform pressure testing on the instrument panel crossbeam. When performing pressure strength testing on instrument panel crossbeams of different specifications, activate the electric cylinder 11 to push the rack 3 to slide in the guide rail 21. Push the rack 3 to drive the bidirectional screw 4 to rotate, so that the two movable plates 5 move closer and further apart, adjusting the length of the instrument panel crossbeam on the connecting bracket 6. After adjustment, repeat the above operation for testing.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
