Description

Technical Field

[0001] This utility model relates to the field of stamping strength testing technology, and in particular to a strength testing device for stamping parts of new energy vehicles. Background Technology

[0002] With the rapid development of the new energy vehicle industry, the requirements for lightweighting and safety of vehicle bodies and components are constantly increasing. Stamped parts, as an important component of the vehicle body structure, need to possess good strength and impact resistance. During the production process of new energy vehicles, the strength of stamped parts needs to be tested to verify their impact resistance and structural reliability during use. Current strength testing methods for stamped parts mostly employ impact testing, which involves applying external force to the stamped parts using an impact device to assess their impact resistance and deformation.

[0003] A Chinese patent has been published: an impact testing device, patent announcement number: CN221465151U. This patent "includes a bottom box, in which a perforated plate for supporting building material test blocks is fixedly connected to the middle position of the bottom box. A rectangular opening is provided on one side of the bottom box, and a drawer box for collecting building material debris is inserted into the rectangular opening. Vertical plates are installed on the two sides of the bottom box adjacent to the rectangular opening. A horizontal plate is provided on the top of the bottom box, and the two ends of the horizontal plate are respectively connected to the upper ends of the two vertical plates. A first strip groove is provided on the upper surface of the horizontal plate along the length direction of the horizontal plate."

[0004] Although the device uses an impact head to perform impact testing on the object, thereby collecting the debris after impact testing and preventing it from scattering randomly, the existing impact testing equipment usually only relies on the testing platform for simple placement or limiting when using new energy vehicle stamping parts for strength testing. It does not have a dedicated clamping mechanism to fix the object to be tested. As a result, during the actual impact testing process, due to the large instantaneous impact force, the stamping parts often shift or are even directly knocked away after being subjected to force. This not only affects the accuracy and repeatability of the test data, but may also cause equipment damage or safety hazards during the testing process, making it difficult to meet the stability requirements of strength testing for new energy vehicle stamping parts. Utility Model Content

[0005] In view of this, the purpose of this utility model is to propose a strength testing device for stamped parts of new energy vehicles, so as to solve the problem that the lack of a dedicated clamping mechanism to fix the object to be tested often causes the stamped parts to shift or even be directly knocked away after being subjected to force, affecting the accuracy and repeatability of the test data.

[0006] To achieve the above objectives, this utility model provides a strength testing device for stamped parts of new energy vehicles, including a support base, a sliding frame fixedly connected to the top of the support base, a placement box for placing stamped parts slidably connected to the bottom of the sliding frame, a sliding plate slidably connected to the outer wall of the sliding frame, an impact hammer fixedly connected to the bottom of the sliding plate, a hydraulic rod fixedly connected between the top of the sliding plate and the top of the inner wall of the sliding frame, and a clamping mechanism for automatically clamping the stamped parts is provided inside the placement box.

[0007] Preferably, the clamping mechanism includes two sets of slide rails fixedly connected to the bottom of the inner wall of the placement box. The top of each set of slide rails is slidably connected to a clamping plate via a slider. The clamping plates are arranged opposite to each other and are L-shaped. A linkage plate is slidably connected to the bottom of the inner wall of the placement box. The top of the linkage plate has two moving slots, which are inclined. The bottom of each clamping plate is fixedly connected to a sliding column, the bottom end of which is slidably connected inside the moving slot. A reciprocating spring is fixedly connected between the opposing surfaces of the linkage plate and the slide rail. A guide wheel is fixedly connected to the inner wall of the placement box. A pull rope is fixedly connected between the side wall of the linkage plate and the bottom of the sliding plate. The outer wall of the guide wheel is in contact with the outer wall of the pull rope.

[0008] Preferably, the side wall of the placement box has a through groove, and the side wall of the linkage plate is fixedly connected to a limiting plate. The limiting plate passes through the through groove, which is L-shaped. The side wall of the limiting plate is provided with a limiting post for limiting the linkage plate when clamping it. The outer wall of the limiting post is fitted with a compression spring. The two ends of the compression spring are fixedly connected to the side wall of the limiting plate and the outer wall of the limiting post, respectively. The side wall of the placement box has multiple slots that are evenly distributed at equal intervals. The end of the limiting post near the placement box is adapted to the inner wall of the slot.

[0009] Preferably, a pressure sensor for monitoring the impact force of the stamped part is fixedly connected to the top of the support base, and a spring damping rod is fixedly connected to the top of the pressure sensor. The top of the spring damping rod is fixedly connected to the bottom of the placement box.

[0010] Preferably, each of the two clamping plates has a plurality of equally spaced and uniformly distributed placement rods fixedly connected to its opposite side, and the placement rods on the opposite side of the two clamping plates are staggered.

[0011] Preferably, the end of the limiting post near the slot has an arc-shaped structure.

[0012] Preferably, when the top of the sliding plate moves upward, it pulls the pull rope, which in turn pulls the linkage plate to slide and compresses the reciprocating spring. When the linkage plate moves, it drives the moving groove to move. When the moving groove moves, it drives the clamping plates to move closer to each other and clamp the stamping part through the sliding column.

[0013] The beneficial effects of this utility model are: This strength testing equipment for new energy vehicle stamped parts uses a hydraulic rod to drive a sliding plate upwards. Pulling a rope causes a guide wheel to guide a linkage plate to slide along the inner wall of the placement box, compressing a reciprocating spring. The linkage plate then moves a moving groove and a sliding column, pushing two clamping plates closer together, thus clamping the stamped parts inside the placement box and achieving automatic clamping and fixing. Simultaneously, a limit plate moves a limit post, which is positioned by inserting a compression spring into a slot, ensuring reliable and stable clamping. This clamping mechanism effectively prevents the stamped parts from shifting or being thrown away during the impact of the falling hammer, ensuring the accuracy and repeatability of the test data and reducing equipment damage and safety risks. This solves the problem of unstable impact testing caused by the lack of clamping and fixing in existing technologies. Attached Figure Description

[0019] like Figures 1 to 5 As shown, a strength testing device for stamped parts of new energy vehicles includes a support base 1, a sliding frame 2 fixedly connected to the top of the support base 1, a placement box 3 for placing stamped parts slidably connected to the bottom of the sliding frame 2, a sliding plate 4 slidably connected to the outer wall of the sliding frame 2, an impact hammer 5 fixedly connected to the bottom of the sliding plate 4, a hydraulic rod 6 fixedly connected between the top of the sliding plate 4 and the top of the inner wall of the sliding frame 2, and a clamping mechanism for automatically clamping the stamped parts is provided inside the placement box 3.

[0020] Further, see attached document. Figures 3 to 5As shown, the clamping mechanism includes two sets of slide rails 7 fixedly connected to the bottom of the inner wall of the placement box 3. Each set of slide rails 7 has a clamping plate 8 slidably connected to its top via a slider. The clamping plates 8 are arranged opposite each other and are L-shaped. A linkage plate 9 is slidably connected to the bottom of the inner wall of the placement box 3. Two moving slots 10 are formed on the top of the linkage plate 9, and the two moving slots 10 are inclined. A sliding column 11 is fixedly connected to the bottom of each clamping plate 8, and the bottom end of the sliding column 11 is slidably connected inside the moving slot 10. A reciprocating spring 12 is fixedly connected between the opposing surfaces of the linkage plate 9 and the slide rails 7. A guide wheel 13 is fixedly connected to the inner wall of the placement box 3. A pull rope 14 is fixedly connected between the side wall of the linkage plate 9 and the bottom of the sliding plate 4. The outer wall of the guide wheel 13 contacts the outer wall of the pull rope 14. The side wall of the placement box 3 is provided with a through groove 15. The side wall of the linkage plate 9 is fixedly connected to a limiting plate 16. The limiting plate 16 passes through the through groove 15. The through groove 15 is L-shaped. The side wall of the limiting plate 16 is provided with a limiting post 17 for limiting the linkage plate 9 when clamping. The outer wall of the limiting post 17 is fitted with a compression spring 18. The two ends of the compression spring 18 are fixedly connected to the side wall of the limiting plate 16 and the outer wall of the limiting post 17, respectively. The side wall of the placement box 3 is provided with multiple slots 19 that are evenly distributed at equal intervals. The end of the limiting post 17 near the placement box 3 is adapted to the inner wall of the slot 19. The end of the limiting post 17 near the slot 19 is arc-shaped. When the sliding plate 4 moves upward under the drive of the hydraulic rod 6, it will drive the pull rope 14 connected to its bottom to move. Under the action of the guide wheel 13, the pull rope 14 pulls the linkage plate 9 to slide along the inner wall of the placement box 3, thereby compressing the reciprocating spring 12 between the linkage plate 9 and the slide rail 7. The pull rope 14 is an elastic rope made of rubber core and multiple layers of nylon. During the movement of the linkage plate 9, the top moving groove 10 moves together with it. The moving groove 10 has an inclined structure, and the sliding column 11 located in it slides accordingly, thereby pushing the two clamping plates 8 closer to each other. Multiple staggered placement rods 22 are provided on the opposite surfaces of the two clamping plates 8. During the closing process, the stamping parts placed in the placement box 3 are gradually clamped. The L-shaped clamping plates 8 facilitate the placement and clamping of the stamping parts, thereby realizing the automatic clamping and fixing of the stamping parts. When the linkage plate 9 moves, the limiting plate 16 slides synchronously in the through groove 15, and then drives the limiting post 17 to move. When it moves to the appropriate position, the limiting post 17 enters the slot 19 through the elastic force of the compression spring 18 to limit it, so that it can only move in one direction. This can then position the linkage plate 9, ensuring the reliability and stability of the clamping position, and preventing the stamped part from being displaced or knocked away during the impact of the impact hammer 5. This effectively solves the problem of inaccurate detection results and safety hazards caused by the lack of a clamping mechanism in the prior art.

[0021] Further, see attached document. Figure 2 As shown, a pressure sensor 20 for monitoring the impact force of the stamped part is fixedly connected to the top of the support base 1, and a spring damping rod 21 is fixedly connected to the top of the pressure sensor 20. The top of the spring damping rod 21 is fixedly connected to the bottom of the placement box 3. By installing a pressure sensor 20 on the top of the support base 1 and connecting it to a spring damping rod 21 at the bottom of the placement box 3, the magnitude of the impact force on the stamped part can be monitored in real time during the impact detection process when the hydraulic rod 6 drives the impact hammer 5 to smash the object downwards. At the same time, the spring damping rod 21 is used to buffer and reduce the impact force, effectively avoiding damage to the placement box 3 and the pressure sensor 20 body during the impact process, thus improving the accuracy of the detection data and the reliability of the equipment.

[0022] Further, see attached document. Figure 4 As shown, multiple equally spaced and evenly distributed placement rods 22 are fixedly connected to the opposite sides of the two clamping plates 8, and the placement rods 22 on the opposite sides of the two clamping plates 8 are staggered. When clamping stamped parts, it can form multi-point support and uniform force, avoiding local damage to the surface of stamped parts caused by single-point clamping. At the same time, it improves the stability and anti-displacement ability of clamping, thereby ensuring the fixation effect of stamped parts during impact testing.

[0023] Further, see attached document. Figure 3 and Figure 4 As shown, when the top of the sliding plate 4 moves upward, it will pull the pull rope 14. The pull rope 14 will pull the linkage plate 9 to slide and compress the reciprocating spring 12. When the linkage plate 9 moves, it will drive the moving groove 10 to move. When the moving groove 10 moves, it will drive the clamping plates 8 to move closer to each other and clamp the stamping part through the sliding column 11. When the sliding plate 4 moves upward, the pull rope 14 drives the linkage plate 9 to slide and compress the reciprocating spring 12. The movement of the linkage plate 9, through the cooperation of the inclined moving groove 10 and the sliding column 11, drives the clamping plates 8 to move closer to each other and realize the automatic clamping of the stamping part. It can achieve fast and reliable fixation before impact testing. After the test is completed, the clamping plate 8 is automatically reset under the action of the spring, forming a convenient automatic clamping and release process, which improves the efficiency and automation of the testing operation.
