Description

Technical Field

[0001] This utility model relates to the field of automotive parts testing technology, and in particular to an impact device for testing automotive parts. Background Technology

[0002] Impact testing devices generally refer to equipment used to apply impact or collision forces to test the performance and durability of materials, components, or products under impact. Automotive component testing impact testing devices, on the other hand, are used to test and evaluate the impact resistance of components during collisions or accidents. These devices help automakers and suppliers ensure that their components meet safety standards and performance requirements under various conditions.

[0003] Traditional automotive parts testing impact devices consist of a bracket, base, and ball drop system. First, the operator places the part to be tested on the base. Then, according to the requirements, the impact ball is installed and the control system releases the ball drop device, allowing it to fall freely from a predetermined height to simulate specific impact conditions. The ball hits the automotive parts or materials to be tested, applying impact force. Sensors and data acquisition systems record the data generated during the impact to complete the test.

[0004] Traditional impact testing devices for automotive parts fail to effectively secure the parts during impact testing, causing them to shift position or even fly off after impact. To address this issue, a new impact testing device for automotive parts is proposed. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides an impact device for testing automotive parts, which aims to improve the problem in the prior art where the parts are not effectively fixed during impact testing, causing them to shift in position or even fly off after being impacted.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An impact device for testing automotive parts includes a base, an upper mounting plate fixedly connected to the upper surface of the base, a fixed plate on the upper surface of the mounting plate, a sliding assembly on the upper surface of the mounting plate for sliding the fixed plate, a clamping plate fixedly connected to the upper surface of the fixed plate, a rack fixedly connected to the lower surface of the fixed plate, a fixing column fixedly connected to the upper surface of the mounting plate, a gear rotatably connected to the side wall of the fixing column, the gear meshing with the rack, a hydraulic rod fixedly connected to the bottom of the mounting plate, a fixing block fixedly connected to the output end of the hydraulic rod, the upper surface of the fixing block fixedly connected to the lower surface of one side of the fixed plate, and a testing plate on the upper surface of the mounting plate.

[0008] As a further description of the above technical solution:

[0009] The upper surface of the base is fixedly connected to the second mounting plate. The second mounting plate has a sliding groove inside. A sliding plate is slidably connected inside the second mounting plate. The side wall of the sliding plate is slidably connected inside the sliding groove. The side wall of the sliding plate is fixedly connected to the second fixing plate. A magnetic attraction device is fixedly connected to the lower surface of the second fixing plate. An impact ball is provided on the lower surface of the magnetic attraction device.

[0010] As a further description of the above technical solution:

[0011] The sliding assembly includes a sliding bar, the lower surface of which is fixedly connected to the upper surface of the mounting plate, and a slider is slidably connected to the side wall of the sliding bar, the upper surface of which is fixedly connected to the lower surface of the mounting plate.

[0012] As a further description of the above technical solution:

[0013] The sliding plate is provided with a rack 2 on its side wall, and a rotating column is rotatably connected inside the mounting plate 2;

[0014] As a further description of the above technical solution:

[0015] A second gear is fixedly connected to the side wall of the rotating column, and the second gear meshes with the second rack.

[0016] As a further description of the above technical solution:

[0017] The mounting plate 2 is rotatably connected to a connecting column, and a worm gear is fixedly connected to the side wall of the connecting column;

[0018] As a further description of the above technical solution:

[0019] A worm gear is fixedly connected to the side wall of the rotating column, and the worm gear meshes with the worm.

[0020] As a further description of the above technical solution:

[0021] One end of the connecting column is fixedly connected to a rotating rocker arm, and the side wall of the rotating rocker arm is rotatably connected inside the second mounting plate.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, by activating the hydraulic rod, the fixing block is pushed. The pushing of the fixing block causes the slider to slide along the side wall of the sliding strip, causing the rack to rotate and the gear meshing with it to rotate, thereby driving the rack on the other side to rotate, thus causing the fixing plate on the other side to slide, thereby causing the position of the clamping plate to shift, achieving the effect of fixing the automotive parts. This solves the problem that some impact devices used for testing automotive parts do not effectively fix the parts during impact testing, causing the parts to shift in position or even fly off after being impacted. The above structure improves the stability of the equipment.

[0024] 2. In this utility model, by rotating the rocker arm, the connecting column is rotated, which in turn drives the worm gear to rotate, thereby causing the rotating column to rotate. The gear on its side wall meshes with the rack and pinion, causing the sliding plate to slide inside the mounting plate, thus achieving the effect of adjusting the height of the sliding plate. This solves the problem that some impact devices for testing automotive parts cannot adjust the impact force of the impact ball according to different needs. The above structure improves the practicality of the equipment. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1 and Figure 2 An embodiment of this utility model provides an impact device for testing automotive parts, comprising a base 1, an mounting plate 2 fixedly connected to the upper surface of the base 1, a fixing plate 5 provided on the upper surface of the mounting plate 2, a sliding assembly for sliding the fixing plate 5 on the upper surface of the mounting plate 2, a clamping plate 6 fixedly connected to the upper surface of the fixing plate 5, a rack 11 fixedly connected to the lower surface of the fixing plate 5, a fixing column 9 fixedly connected to the upper surface of the mounting plate 2, a gear 10 rotatably connected to the side wall of the fixing column 9, the gear 10 meshing with the rack 11, a hydraulic rod 7 fixedly connected to the bottom of the mounting plate 2, a fixing block 8 fixedly connected to the output end of the hydraulic rod 7, the upper surface of the fixing block 8 fixedly connected to the lower surface of one side of the fixing plate 5, a testing plate 12 provided on the upper surface of the mounting plate 2, and a sliding component including a sliding strip 3, the lower surface of the sliding strip 3 fixedly connected to the upper surface of the mounting plate 2, a slider 4 slidably connected to the side wall of the sliding strip 3, and the upper surface of the slider 4 fixedly connected to the lower surface of the fixing plate 5.

[0032] In the process of performing impact testing on automotive parts, the stability of the part to be tested is crucial. First, the operator accurately places the part to be tested on the top of the test plate 12. Then, the operator needs to activate the hydraulic rod 7. Through the pushing action of the hydraulic rod 7, the fixing block 8 begins to move. As the slider 4 is subjected to the force from the fixing block 8, it will start to drive the fixing plate 5 and the clamping plate 6 to slide towards the center along the side wall of the sliding strip 3. As the fixing plate 5 begins to slide, the rack 11 at its bottom also moves, which in turn causes the gear 10 meshing with it to rotate. The rotation of the gear 10 drives the rack 11 on the other side to slide. This interaction eventually causes the fixing plate 5 and the clamping plate 6 on the other side to slide towards the center as well. When the clamping block is completely attached to the side wall of the part to be tested, it means that the part has been successfully fixed. The completion of this process provides a solid foundation for the subsequent impact test, ensuring the accuracy of the test and the safety of the part.

[0033] Reference Figure 1 and Figure 3A mounting plate 15 is fixedly connected to the upper surface of the base 1. A groove 25 is provided inside the mounting plate 15. A sliding plate 16 is slidably connected inside the mounting plate 15. The side wall of the sliding plate 16 is slidably connected inside the groove 25. A fixing plate 17 is fixedly connected to the side wall of the sliding plate 16. A magnetic suction device 13 is fixedly connected to the lower surface of the fixing plate 17. An impact ball 14 is provided on the lower surface of the magnetic suction device 13. A rack 18 is provided on the side wall of the sliding plate 16. A rotating column 19 is rotatably connected inside the mounting plate 15. A gear 20 is fixedly connected to the side wall of the rotating column 19. The gear 20 meshes with the rack 18. A connecting column 23 is rotatably connected inside the mounting plate 15. A worm 22 is fixedly connected to the side wall of the connecting column 23. A worm wheel 21 is fixedly connected to the side wall of the rotating column 19. The worm wheel 21 meshes with the worm 22. A rocker arm 24 is fixedly connected to one end of the connecting column 23. The side wall of the rocker arm 24 is rotatably connected inside the mounting plate 15.

[0034] When the height of the sliding plate 16 needs to be adjusted to conduct pressure impact tests at different heights, the operator first needs to manually rotate the rocker arm 24. This action causes the connecting column 23 to rotate, which in turn drives the worm gear 22 to rotate. As the worm gear 22 rotates, the worm wheel 21 meshing with it also begins to rotate. The rotation of the worm wheel 21 is transmitted to the rotating column 19 through a mechanical linkage mechanism. The rotation of the rotating column 19 further drives the rotation of the gear 20. Since the gear 20 meshes with the rack 18, the rotation of the gear 20 indirectly drives the rack 18 to move upward. The upward movement of the rack 18 indirectly drives the sliding plate 16 to move upward in the groove 25, ultimately raising the height of the impact ball 14 to conduct impact tests at different heights. Once the sliding plate 16 has moved to the predetermined height position, the operator stops rotating the rocker arm 24, and the impact test can then begin.

[0035] Working Principle: When using this equipment for impact testing of automotive parts, to fix the part to be tested, first place the part on the testing plate 12. Then, the operator activates the hydraulic rod 7. The hydraulic rod 7 pushes the fixing block 8, causing the slider 4 to be subjected to force, which drives the fixing plate 5 and the clamping plate 6 to slide towards the center on the side wall of the sliding strip 3. Due to the sliding of the fixing plate 5, the rack 11 below it moves, which drives the gear 10 meshing with it to rotate, thereby causing the rack 11 on the other side to slide, which in turn drives the fixing plate 5 and the clamping plate 6 on the other side to slide towards the center. When the clamping block is in contact with the side wall of the part to be tested, the part is fixed. Once the height of the sliding plate 16 is adjusted for different pressure impacts, the operator first rotates the rocker arm 24 to rotate the connecting column 23, which in turn rotates the worm gear 22, causing the meshing worm wheel 21 to rotate. The rotation of the worm wheel 21 causes the rotating column 19 to rotate, which in turn causes the gear 20 to rotate. Since the gear 20 meshes with the rack 18, the rotation of the gear 20 causes the rack 18 to move upward, which in turn causes the sliding plate 16 to slide upward inside the groove 25, thereby raising the height of the impact ball 14. When the required height is reached, the rocker arm 24 is stopped, and the impact test is performed again.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
